1、PET离型膜上一般应用二甲基硅油,起绝缘感化。
2、PET硅油膜别名PET离型膜 ,就是在PET薄膜的名义涂上一层硅油,以下降PET薄膜名义的附出力,达离型的后果。能够分为单面离型膜跟双面离型膜。按离型力可分为轻离型膜,中离型膜,重离型膜。
3、硅油平日指的是在室温下坚持液体状况的线型聚硅氧烷产物。一般分为甲基硅油跟改性硅油两类。最常用的硅油一甲基硅油,也称为一般硅油,其无机基团全体为甲基,甲基硅油存在精良的化学稳固性、绝缘性,疏水机能好。它是由二甲基二氯硅烷加水水解制得初缩聚环体,环体经裂解、精馏制得低环体,而后把环体、封头剂、催化剂放在一同调聚就可得到种种差别聚合度的混杂物,经减压蒸馏撤除低沸物就可制得硅油。

1, PET off the membrane generally used dimethyl Silicon oil, insulation effect.
2, PET Silicon film alias PET off-film, is the name of PET film coated with a layer of Silicon oil, in order to reduce the PET film name of the auxiliary force, to reach the consequences of off-type. Can be divided into single-sided off-film and double-sided off-film. According to the dissociation force can be divided into light film, medium film, heavy film.
3, Silicon oil refers to linear polysiloxane products that adhere to liquid conditions at room temperature. It is generally divided into methyl Silicon oil and modified Silicon oil. The most commonly used Silicon oil monomethyl Silicon oil, also known as general Silicon oil, its inorganic group is all methyl, methyl Silicon oil has excellent chemical stability, insulation, and hydrophobic function. It is prepared by water hydrolysis of dimethyl dichlorosilane to obtain a initial condensation ring body. The ring body is cracked and distilled to a low ring body, and then the ring body, the sealing agent, and the catalyst are put together to obtain a variety of different polymerization. Mixtures, Silicone oil can be prepared by removing low zeolite by vacuum distillation.
