中国石化新闻网讯 据ICIS-MRC网站9月25日莫斯科报道，根据MRC的DataScope报告显示，今年前八个月，俄罗斯悬浮聚氯乙烯（SPVC）进口总量约为3.2万吨，同比下降13％。 同时，出口增长3％。 上月俄罗斯的SPVC进口从7月份的1.09万吨降至7,400吨。国内生产商的供应增加和国外市场的高价是进口减少的主要原因。因此，今年1 - 8月的总进口为32,000吨，而去年同期为36,900吨，其中来自中国和美国的树脂占进口总量的主要下降。 与此同时，俄罗斯生产商设法增加了出口，尽管生产商通常会在夏季减少出口销售。 由于国内市场需求强劲，俄罗斯生产商上月减少了SPVC出口。8月份的暂停出口未超过7000吨，而一个月前为14000吨。因此，2020年1 - 8月PVC出口总量总计为13.99万吨，而去年同期为13.58万吨。 郝芬 译自 ICIS-MRC 原文如下： PVC imports into Russia down by 13% in Jan-Aug 2020, exports up by 3% Imports of suspension polyvinyl chloride (SPVC) into Russia totalled about 32,000 tonnes in the first eight months of 2020, down by 13% year on year. At the same time, exports rose by 3%, according to MRC"s DataScope report. Last month"s SPVC imports to Russia dropped to 7,400 tonnes from 10,900 tonnes in July. The increased supply from domestic producers and high prices in foreign markets were the main reasons for lower imports. Thus, overall imports were 32,000 tonnes in January-August 2020, compared to 36,900 tonnes a year earlier, with resin from China and the United States accounting for the main decreased in imports. At the same time, Russian producers managed to increase their exports, although producers traditionally reduce their export sales in the summer months. Russian producers reduced their SPVC exports last month because of stronger demand from the domestic market. August exports of suspension did not exceed 7,000 tonnes, compared to 14,000 tonnes a month earlier. Thus, overall PVC exports totalled 139,900 tonnes in January-August 2020 versus 135,800 tonnes a year earlier.
中国石化新闻网讯 据ICIS网站8月5日消息 ICIS-MRC价格报告显示，由于卢布走软以及亚洲和欧洲的价格上涨，俄罗斯聚氯乙烯（PVC）生产商计划在8月份进一步提价。 关于8月份向国内市场供应悬浮聚氯乙烯（SPVC）的谈判于周三开始，计划将价格上调1500-2000卢布/吨（21-27美元/吨）。 7月，由于国外市场价格上涨，以及定期维修停运造成的供应大幅下降，俄罗斯生产商实现了6000卢布/吨以上的涨幅。 俄罗斯市场对悬浮聚氯乙烯的需求在4-5月大幅下降后，6-7月开始出现动态复苏。7月，由于SayanskKhimPlast和Rusvynold计划停产进行维护，一些转换装置无法积累足够的聚合物库存。 随着俄罗斯乙烯本周初恢复生产，转机已经结束。 SayanskKhimPlast将在一周内开始生产聚乙烯，这将增加需求旺盛的市场树脂供应。国内生产商增加的供应可能很容易被转换装置的延迟需求所抵消。 过去几个月进口有所增长，但同比仍大幅下降。国外市场的高价格，尤其是中国和欧洲，卢布对美元的不断贬值以及某些地区的长期交货也对进口产生了负面影响。 商家并不急于就8月份俄罗斯聚氯乙烯的出货量达成协议，希望将价格上涨降到最低。 消费者明白他们将无法避免8月份价格的上涨，但将新的材料价格转移到成品上正变得越来越困难。 8月份俄罗斯树脂（K=64/67）的交易在80000-83500卢布/吨（运费付至莫斯科）的范围内进行了谈判（含增值税），从7月份起增加了1000-2000卢布/吨，数量最多为500吨。 王磊 摘译自 ICIS 原文如下： Russian PVC producers target further price hikes in August Russian polyvinyl chloride (PVC) producers are targeting further price hikes in August because of a weakening rouble and higher prices in Asia and Europe, according to the ICIS-MRC Price report. Negotiations over August shipments of suspension PVC (SPVC) to the domestic market began on Wednesday, with intentions of raising prices by roubles (Rb) 1,500-2,000/tonne ($21-27/tonne). In July, Russian producers achieved an increase of Rb6,000/tonne and more due to higher prices in foreign markets and a significant drop in supply from scheduled maintenance outages. Demand for SPVC in the Russian market began to recover dynamically in June-July after a major decrease in April-May. In July, due to scheduled shutdowns for maintenance at SayanskKhimPlast and RusVinyl, some converters were unable to build up sufficient stocks of polymer. Turnarounds have been coming to an end with RusVinyl resuming production at the beginning of the week. SayanskKhimPlast will begin producing PVC in a week, which should increase supply of resin in the market where demand is strong. Increased supply from domestic producers may be easily offset by deferred demand from converters. Imports have grown in the past few months but remain significantly lower year on year. High prices in foreign markets - particularly China and Europe - the incessant devaluation of the rouble against the dollar and long-term deliveries in certain regions also negatively affected imports. Converters were in no hurry to agree deals for August shipments of Russian PVC, hoping to minimise price increases. Consumers understand they will be unable to avoid a rise in August prices but it is becoming increasingly difficult to transfer new prices of material to finished products. Overall, August deals for Russian resin with K=64/67 were negotiated in the range of Rb80,000-83,500/tonne CPT (carriage paid to) Moscow, including VAT, up by Rb1,000-2,000/tonne from July, for quantities of up to 500 tonnes.
中国石化新闻网讯 据ICIS网站7月30日消息 分析人士称，2020年的第一个季度，莫斯科的聚氯乙烯进口量增加到2400吨。 在季节性因素的压力下，5月份本地企业对聚氯乙烯的需求增加，5月份未混合聚氯乙烯的进口量为5400吨，上月为4200吨。 2020年1-5月，聚氯乙烯总进口量达到2.4万吨，而去年同期为1.93万吨，增加的原因是进一步向俄罗斯转售聚氯乙烯。 1-5月，中国生产商在当地市场占有约94%的份额，是哈萨克斯坦的主要聚氯乙烯供应商。 俄罗斯是第二大聚氯乙烯供应商，1-5月俄罗斯聚氯乙烯的出货量达到3900吨。 王磊 摘译自 ICIS 原文如下： PVC imports to Kazakhstan up by 25% in Jan-May 2020 Imports of unmixed polyvinyl chloride (PVC) into Kazakhstan rose in the first five months of 2020 by a quarter year on year to 24,000 tonnes, reported MRC analysts. Demand for PVC increased from local companies in May under the pressure of seasonal factors, and May imports of unmixed PVC were 5,400 tonnes versus 4,200 tonnes a month earlier. Overall imports of resin reached 24,000 tonnes in January-May 2020, compared to 19,300 tonnes a year earlier, with the increase caused by a further resale of resin to Russia. Chinese producers with the share of about 94% of the local market over the stated period were the main PVC suppliers to Kazakhstan. Russia was the second largest PVC supplier, shipments of Russian resin reached 3,900 tonnes over the stated period.
中国石化新闻网讯 据ICIS网站7月13日消息 MRC的ScanPlast报告显示，2020年1-6月，俄罗斯未混合聚氯乙烯（PVC）总产量为50.93万吨，同比增长1%。 俄罗斯6月未混合聚氯乙烯的产量为7.72万吨，之前一个月为8.11万吨，原因是Kaustik Volgograd关闭了生产能力，进行了一次计划外的检修，同时Bashkir Soda公司也将生产线下线。2020年上半年，聚合物总产量从上年同期的50.26万吨增至50.93万吨，共有三家生产商增加了产量，Bashkir Soda公司减少了聚氯乙烯产量。 今年6月，RusVinyl生产了2.85万吨聚氯乙烯，其中乳液聚氯乙烯（EPVC）产量为2300吨，之前一个月产量为2.99万吨。在2020年的前六个月，RusVinyl的SPVC总产量达到17.71万吨，而去年同期为16.68万吨。 SayanskKhimPlast上个月生产的悬浮聚氯乙烯（SPVC）略高于2.7万吨，而5月份这一数字为2.77万吨。Sayansk工厂在2020年1-6月生产了16.5万吨聚氯乙烯，去年同期为16.25万吨。 Bashkir Soda公司6月中旬因乙烯发货中断而停产5天，最终6月产量从上月的2.2万吨降至1.58万吨。Baskhir工厂的树脂总产量在2020年1-6月达到13.07万吨，同比下降5%。 Kaustik Volgograd在5-6月关闭了生产能力进行维护，因此工厂的PVC总产量分别为1500吨和5900吨。该工厂的树脂总产量在2020年上半年超过3.65万吨，而去年同期为3.6万吨。 王磊 摘译自 ICIS 原文如下： Russia PVC production up 1% in H1 Russia’s overall production of unmixed polyvinyl chloride (PVC) totalled 509,300 tonnes in January-June 2020, up by 1% year on year, according to MRC’s ScanPlast report. June production of unmixed PVC in Russia was 77,200 tonnes versus 81,100 tonnes a month earlier, as Kaustik Volgograd shut its production capacities for an unscheduled turnaround, and Bashkir Soda Company also took production offline for an unplanned maintenance. Overall output of polymer rose to 509,300 tonnes in the first half of 2020 from 502,600 tonnes a year earlier, only three producers increased their production, whereas Bashkir Soda Company reduced its PVC production. RusVinyl produced 28,500 tonnes of PVC in June, with emulsion polyvinyl chloride (EPVC) accounting for 2,300 tonnes, compared to 29,900 tonnes a month earlier. RusVinyl’s overall SPVC output reached 177,100 tonnes in the first six months of 2020, compared to 166,800 tonnes a year earlier. SayanskKhimPlast produced slightly over 27,000 tonnes of suspension PVC (SPVC) last month, whereas this figure was 27,700 tonnes in May. The Sayansk plant managed to produce 165,000 tonnes of PVC in January-June 2020, compared to 162,500 tonnes a year earlier. Bashkir Soda Company shut its PVC production for 5 days in mid-June because of disruptions in ethylene shipments, and as a result, the final June output fell to 15,800 tonnes from 22,000 tonnes a month earlier. The Baskhir plant’s overall production of resin reached 130,700 tonnes in January-June 2020, down by 5% year on year. Kaustik Volgograd shut its production capacities for maintenance in May-June, as a result, the plant’s total PVC output was 1,500 tonnes and 5,900 tonnes, respectively. The plant’s overall production of resin exceeded 36,500 tonnes in the first half of 2020 versus 36,000 tonnes a year earlier.

Behold The Potassium & Proton Batteries Of The Future!
Twitter LinkedIn Facebook April 7th, 2020 by Steve Hanley With hundreds of labs around the world working to find cheaper, safer batteries, reports of breakthroughs are common. Here are two that were announced recently. Proton battery. Image credit: Uppsala University The Potassium Battery Potassium is plentiful and cheap. Lithium is fairly plentiful, but it is not evenly distributed around the world and fairly difficult to refine, which makes it rather costly. Scientists have been exploring the possibility of using potassium instead of lithium in batteries as a way to reduce costs. “The uneven distribution and scarcity of lithium in the Earth’s crust make relying on lithium-ion batteries as the sole source of energy storage highly impractical and uneconomical,” Nikhil Koratkar, a professor of mechanical engineering at Rensselaer Polytechnic Institute, tells OneZero. He and his team have published an article with details of their research in the Proceedings of the National Academy of Sciences. The researchers have found that making the cathode and the anode of their experimental batteries from potassium makes them perform about as well as lithium-based batteries except for one thing. Potassium tends to grow dendrites more easily — sharp spikes of material that can pierce the internal layers of battery cells and lead to fires or explosions. The big news from the team is the discovery that the potassium batteries can smooth those dendrites using self-heating techniques. “Historically, battery self-heating has been viewed negatively as an undesirable attribute. However, we report that battery self-heat, if properly controlled, can smoothen dendritic features in potassium metal batteries. This could open the door to high gravimetric and volumetric energy density potassium-ion batteries that could offer a sustainable and low-cost alternative to the incumbent lithium-ion technology,” the researchers write in a summary of their research for PNAS. “The healing is triggered by current-controlled, self-heating at the electrolyte/dendrite interface, which causes migration of surface atoms away from the dendrite tips, thereby smoothening the dendritic surface. We discover that this process is strikingly more efficient for K as compared to Li metal. “We show that the reason for this is the far greater mobility of surface atoms in K relative to Li metal, which enables dendrite healing to take place at an order-of-magnitude lower current density. We demonstrate that the K-metal anode can be coupled with a potassium cobalt oxide cathode to achieve dendrite healing in a practical full-cell device,” the researchers say in the abstract of their report. OneZero describes the self-heating and self-healing process this way. “Self healing is akin to periodically heating sidewalks, in a controlled way, to toast weeds into oblivion. ‘To our surprise, we found that potassium is far more amenable than lithium for such type of healing,” Koratkar says. Now the team has to scale up their experiments to see if their self-heating and self-healing discoveries translate well to larger batteries. The Proton Battery Can you make a functioning battery using nothing but organic materials? Researchers as Uppsala University in Sweden say the answer is “yes” in a report published by Angewante Chemie entitled “An Aqueous Conducting Redox‐Polymer‐Based Proton Battery that Can Withstand Rapid Constant‐Voltage Charging and Sub‐Zero Temperatures.” They say their proton battery can be charged in seconds and can withstand at least 500 charge/discharge cycles. Among other advantages, the proton battery requires no advanced battery management system and functions just as well at -24º C as it does at room temperature. “I’m sure that many people are aware that the performance of standard batteries declines at low temperatures. We have demonstrated that this organic proton battery retains properties such as capacity down to as low as -24°C,” says Christian Strietzel of Uppsala University. A great many of the batteries manufactured today have a major environmental impact due to the mining of the metals used in them. “The point of departure for our research has therefore been to develop a battery built from elements commonly found in nature and that can be used to create organic battery materials,” Strietzel explains. The researchers chose quinones for the active material in their battery. These organic carbon compounds are plentiful in nature and occur naturally during photosynthesis. Quinones absorb and emit hydrogen ions — otherwise known as protons — during charging and discharging. An acidic aqueous solution has been used as an electrolyte — the component that transports ions inside the battery. As well as being environmentally friendly, it also provides a safe battery that will not explode or catch fire. “There remains a great deal of further development to be done on the battery before it becomes a household item. However, the proton battery we have developed is a large stride towards being able to manufacture sustainable organic batteries in future,” Strietzel says. The Takeaway Both of these research studies have proven successful in laboratory conditions. Now the hard work begins to make them commercially viable. The issue is not finding a way to replace lithium-ion batteries. The issue is finding other batteries that can do things lithium-ion batteries cannot so the world has a range of energy storage products to meet every need at an affordable price. Close your eyes and just imagine where battery technology will be in 5 years. The future’s so bright, we gotta wear shades! Follow CleanTechnica on Google News. It will make you happy & help you live in peace for the rest of your life.

中国石化新闻网讯 据ICIS网站3月12日伦敦报道 根据ICIS的分析，欧洲2020年较低的GDP增长可能会减少对聚合物的需求，尽管去库存效应可能不如2008-2009年金融危机时明显。 目前有三个相互关联的因素正在影响欧洲和全球的聚合物需求：原油价格下跌、冠状病毒和总体经济不景气。 显然，这些因素并不相互独立：冠状病毒的需求减弱加剧了经济萎靡和油价疲软。 国内生产总值预测几乎每天都在下调。 冠状病毒的爆发和各国政府的封锁已经导致需求下降。 牛津经济研究院驻伦敦的分析师将欧盟今年的GDP增长预期下调至0.6%，为7年来最低，比一年前的预测低了约1.3个百分点。 理论上，这导致整个欧洲地区对塑料的需求减少。 受冲击最大的是用于服装的聚酯纤维、聚氯乙烯（PVC）和聚丙烯（PP）。 通过回归分析法，对于许多聚合物而言，0.6%的GDP增长率可以转化为2020年树脂需求的下降，其中聚氯乙烯和低密度聚乙烯（LDPE）可能下降约1.5%。 王磊 摘译自 ICIS 原文如下： Europe polymers demand to be hit by slowing GDP growth Europe's lower GDP growth in 2020 could cut demand for polymers, although the destocking effect may be less pronounced than in the 2008-2009 financial crisis, according to analysis by ICIS. Three interlinked factors are currently impacting polymer demand in Europe and globally: lower crude oil prices, coronavirus, and general economic malaise. These factors are not independent of each other, obviously: weaker demand from the coronavirus adds to the economic malaise and weak oil prices. GDP forecasts are being downgraded on an almost daily basis. The coronavirus outbreak and, more importantly, lockdown efforts by national governments have already led to lower demand. London-based analysts at Oxford Economics have cut GDP growth forecasts for the eurozone to 0.6% this year, the weakest in seven years, and around 1.3 percentage points lower than forecasts a year ago. In theory this leads to a cut in demand for plastics across the European region. The most impacted are polyester fibres which are used for clothing, polyvinyl chloride (PVC) and polypropylene (PP). Using regression analysis, we can see that for many polymers the 0.6% GDP growth rate could translate as a fall in demand for resin in 2020, with PVC and low density polyethylene (LDPE) likely to be down around 1.5%.
中国石化新闻网讯 据ICIS网站3月4日莫斯科报道 根据MRC价格报告，由于库存低迷和卢布货币走软，俄罗斯国内聚氯乙烯（PVC）生产商打算在3月份提价。 良好的出口销售帮助俄罗斯生产商平衡了国内聚氯乙烯市场。 卢布对美元的贬值降低了出口对当地生产商的吸引力。 俄罗斯生产商表示，打算将3月份的价格上调2000-3000卢布/吨（30-46美元/吨）。 俄罗斯的一些转化装置在2月中旬报告了一些生产商的供应限制，一些公司已经敲定了2月份出货的交易。 因此，生产商进入3月份时库存较低。 过去几个月，欧美聚氯乙烯出口价格有所上涨，这一趋势在3月份不太可能逆转。 过去两周，俄罗斯卢布兑美元和欧元明显走软，这一因素将阻碍俄罗斯生产商获得相对廉价的进口聚氯乙烯。 3月份俄罗斯K64/67聚氯乙烯树脂的交易在7.4-7.6万卢布（运费付至莫斯科，含增值税）的价格范围内进行，交易数量少于500吨。 与2月份相比，1000-2000卢布/吨的K70树脂供应量有所增加。 （1美元=65.83卢比） 王磊 摘译自 ICIS 原文如下： Russia PVC prices rise in March on low stocks, rouble depreciation Russia’s domestic polyvinyl chloride (PVC) producers intend to increase prices in March on the back of low stocks and a weakening rouble, according to an MRC Price Report. Good export sales helped Russian producers balance the domestic PVC market. The weakening of the rouble against the US dollar has reduced the attractiveness of exports for local producers. Russian producers said they intend to increase March prices by Russian roubles (Rb) 2,000-3,000/tonne ($30-46/tonne). Some converters in Russia reported supply restrictions from some producers in mid-February, and some companies have already finalised their deals for February shipments. And as a result, producers entered March with low stocks. PVC export prices in Europe and the US have increased in past months, a trend unlikely to be reversed in March. The Russian rouble weakened noticeably against the dollar and the euro in the past two weeks, a factor which will impede Russian producer accessing unexpansive imported PVC. Overall, deals for March shipments of Russian resin with K64/67 PVC were negotiated in the range of Rb74,000-76,000/tonne CPT (carriage paid to) Moscow, including VAT, for quantities of less than 500 tonnes. Resin with K70 was offered by Rb1,000-2,000/tonnes higher compared to February. ($1 = Rb65.83)
中国石化新闻网讯 据ICIS网站2月12日莫斯科报道 据MRC的ScanPlast报告，俄罗斯1月份的聚氯乙烯（PVC）总产量为9.17万吨，同比增长4%。 1月份的产量也从12月份的8.14万吨强劲增长。 尽管国内市场对树脂的需求相对较弱，但1月份俄罗斯聚氯乙烯工厂的平均产能利用率超过95%。 俄罗斯2019年的聚氯乙烯产量总计为97.5万吨，上年同期为95.86万吨。 王磊 摘译自 ICIS 原文如下： Russia’s PVC January output up 4% Russia’s polyvinyl chloride (PVC) output totalled 91,700 tonnes in January, up 4% year on year, according to MRC’s ScanPlast report. January’s output also rose strongly from December’s 81,400 tonnes. Despite relatively weak demand for resin from the domestic market, the average capacity utilisation exceeded 95% in Russian PVC plants in January. Russia’s PVC production totalled 975,000 tonnes in 2019, compared to 958,600 tonnes a year earlier.
