1) PVC content
PVC含量
1.
It is difficult to get the readout of the content of each ingredient directly from the TG curve due to the complication of PVC material, it needs to calculate and translate the measured results into PVC content through the linear regression equation.
详细介绍对于未知PVC样品先用裂解法制样进行红外光谱分析初步定性,再用溶解法制样进行红外光谱分析验证;PVC材料热分解过程较复杂,不能直接从热重检测结果(TG曲线)读出各组分含量,需将检测结果通过线性回归方程计算得出PVC的含量,PVC含量在30%~80%范围内具有较好的线性关系(R=0。
2) the quality of PVC
PVC质量
3) PVC dosage
PVC用量
1.

本文主要论述了在ABS/PVC共混体系中PVC用量对共混体系性能的影响，同时发现，所研究开发的Z117合金性能上达到PA766指标。
5) polyvinyl chloride
PVC
1.
Application of high - purity hydrogen chloride-byproduct from potassium sulfate production in polyvinyl chloride production;
K_2SO_4装置副产高纯度HCl在PVC生产中的应用
2.
The effect of CaCO3 nanoparticle and acrylic rubber content on the mechanical properties of polyvinyl chloride(PVC) was studied.
研究了纳米碳酸钙和丙烯酸酯橡胶(ACR)二元增韧聚氯乙烯(PVC)材料,主要考察了丙烯酸酯橡胶以及纳米碳酸钙用量对PVC力学性能的影响,并采用扫描电镜、透射电镜对复合材料的结构进行了观察。
3.
Sealing strip using in automobile door or window was produced by using the polyvinyl chloride(PVC) elastomerics of high polymerization degree as host resin which was modified by blending with nitrile-butadiene rubber(NBR).
以高聚合度PVC弹性体为主体树脂,用丁腈橡胶进行共混改性制备了汽车门窗密封条;对试样进行了硬度、拉伸强度、断裂伸长率、热老化等性能试验;对老化后的试样表面进行了SEM表征。
6) Poly(vinyl chloride)
PVC
1.
Study on Properties and Preparation of Ultrafiltration Membrane from Polyurethane/Poly(vinyl chloride) Blends;
PU/PVC共混超滤膜的制备及性能
2.
Poly(vinyl chloride) was aminated by ethanolamine in DMF and aminated polymers with different content of nitrogen were made under the optimum reaction conditions : the reaction temperature 80℃, molar rate of amine to poly(vinyl chloride) 11, the reaction time within 36h ,and the reaction pressure 2.
确定了最佳反应条件:温度80℃,PVC结构单元与乙醇胺的摩尔比1/1,反应时间小于36 h,反应压力2。
3.
The comprehensive information in both gas phase and condensed phase can be acquired by using cone calorimeter which was used to investigate the synergistic effect of Cu 2O and MoO 3 on flame retardance and smoke suppression of poly(vinyl chloride)(PVC) in this paper.
用锥形量热仪 (CONE)研究Cu2 O/MoO3 体系对PVC的阻燃和抑烟协同效应可以同时获得气相和凝聚相的综合信息。

FangZhiPin Xian明1 Honliong de BiaOZhi《纺织品纤维含t的标识》(万刀T 01053一1998)(爪荡￡幼郎.加匆刁以勿nof踢。。几饱瓜)纤维种类及其含量是纺织品品质标志的重要内容之一。根据纺织制品形式和结构，提出了标注纤维含t的具体要求，解决了不同产品标识的统一问题，如带里料的产品应对里和面分别标注;带填充物的产品应把填充物和套分别标注;二种以上的不同织物拼接或镶嵌的产品应分别标注不同织物;只起装饰作用而不作为产品主体的可以不标。规定统一采用国家标准规定的纤维名称，避免了任意标注商品名称、外来语名称等造成的纤维名称混乱问题;规定了以成品中某种纤维的量占纤维总量的百分数表示，而不以生产实际的投料比例标注，解决了纤维含t概念(即基数不清)的问题。明确规定了各种纺织品的纤维含量允差，既与原有的纺织品标准衔接，又明确了各种单一纤维纯纺、二组分或多组分纤维混纺或交织产品的明示含t值与实际值可允许的差值，使标准具有可操作性，解决了含t偏差判定的根本问题，使市场抽查有据可依。对统一纤维成分及其含量的标识起到了积极的指导作用，对保护消费者的利益，维护生产者的合法权益有着重要意义。(郑宇英)
