Sampling and testing carbon black for use in the rubber industry - preparation of samples for determination of dibutyl phthalate absorption number compressed sample 橡胶工业用炭黑的取样和试验方法.用于测定邻苯二甲酸二丁酯吸收数的样品制备
Toluene is a colorless liquid used as a solvent , formaldehyde helps harden nails and dibutyl phthalate is a plasticizer that makes nail polish flexible 甲苯是一种无色液体，用做溶媒；甲醛帮助硬化指甲；而邻苯二甲酸二丁酯是一种增塑剂，增强指甲油的柔韧性。
A quantitative analytical method of 5 % diethylmethylbenzamide in drive - worms floral - water by gc was introduced , dibutyl phthalate was selected as internal standard 摘要本文介绍了以邻苯二甲酸二丁脂为内标物，对5 %避蚊胺驱虫花露水进行有效成份测定的气相色谱分析法。
California law requires the government to list products containing chemicals that cause cancer or birth defects , and three compounds long used in nail salons ? toluene , formaldehyde and dibutyl phthalate ? are on the list 加州法律要求政府列出含有致癌或致畸化学品的产品，而该清单中有三种长期应用于美甲行业- - -甲苯、甲醛和邻苯二甲酸二丁酯。

This article is about the polymer separator full of holes , we research the performance of the separator , including making two kinds separters that produce wth complete different methods : spreading the separator , pvdf as the basic material , dbp as the plasticizing agent , nm sio2 as the inorganic addition and acetone as the solvent , and make separator on the special machine ; dipping in the separator so that intensify the seprater , its dip liquor is as the liqure as the spreading separator , and dip the base material pp / pe / pp into the liquor for more than 2 hours 本文对多孔聚合物电解质隔膜进行了综合研究。以聚偏氟乙烯( pvdf )为基体,邻苯二甲酸二丁酯( dbp )为增塑剂,纳米sio2为无机添加剂,丙酮为溶剂,在流延机上涂布得到了聚合物电解质隔膜。以流延法制备隔膜的浆料为处理液,将基体材料pp / pe / pp浸泡在处理液中2h以上,制备出强化电解质隔膜。
Making spreading separator , and research the influence of dbp ’ s percentum and the dry tempareture . in order to find the influence of the succedent disposal , i have reseached the water disposal , the ultraviolet radiation disposal and the water disposal with the ultraviolet radiation disposal . making separator by dipping method , and research the influence of dbp ’ s and inorganic additive nm sio2 ’ s percentum mainly 探讨了增塑剂邻苯二甲酸二丁酯( dbp )含量以及干燥温度对隔膜性能的影响;研究了紫外照射、水浴后处理对隔膜机械强度及其他性能的影响;考察了增塑剂含量以及无机添加剂纳米sio2含量对强化电解质隔膜性能的影响。
Abstract : in the paper the deterrent content and the concentration of diphenylamine dibuty l phthalate and centralite in finished product manufactured by two different methods were analyzed by high performance liquid chromatography , which can provi dereference for adjusting the technology of the propellant manufacture 文摘:利用高效液相色谱仪分别测定了发射药在两种制备工艺中的钝感剂邻苯二甲酸二丁酯和二号中定剂的含量及邻苯二甲酸二丁酸在其中的浓度梯度分布，为调整发射药制备工艺提供了参考。
