硅胶管的低贱 有哪些


有机硅是众多产品 的商业称号 ,但大少数 由聚二甲基硅氧烷(PDMS)制成。这些聚合物的特点是共价键强度高,抗均裂断链(有机硅具有紫外线(UV)动摇 性;也具有热动摇 性和化学动摇 性,以是 容易灭菌)。其极性主链易发作 异裂断链,但链上的甲基基团可提供掩护作用。

硅胶管的低贱
有哪些

Organosilicon is the commercial name of many products, but it is mostly made from poly two methylsiloxane (PDMS). These polymers are characterized by high covalent bond strength, anti split chain fracture chain (organosilicon with UV (UV) stability, thermal stability and chemical stability, so it is easy to sterilize). The main chain of its polar chain is liable to undergo cleavage, but the methyl group on the chain can provide protection.


是以 ,有机硅具有疏水性,水在聚二甲基硅氧烷(PDMS)模子 外貌的接触角较高,为 108°。因为 这种疏水性,在缺少 外貌活性剂的情形 下,有机硅与水介质不发作 反映,仅在强碱或强酸的情形 中才会发作 反映。


Therefore, silicone has hydrophobicity and water contact angle on the surface of poly two methylsiloxane (PDMS) model is 108 degrees. Because of this hydrophobicity, in the absence of surfactants, the organosilicon does not react with the water medium, only in the environment of strong alkali or strong acid.


软管在挤出成型后包装供应 ,一样往常 为 50 英尺线圈型,独自 装在双层密封聚乙烯袋中。值得一提的是,因为 硅氧烷具有热固性,它们不行 被再加工似乎 热塑性塑料。出于异样 的缘故原由 ,它们不行 热密封;是以 ,毗邻 时,硅胶管套在软管倒钩讨论 上,并用两根扎带从相反倾向 系牢,牢靠 好软管。共模压成型是可行的,偶然 用于医疗器械范围 。


The hose is supplied after extrusion, generally 50 feet coil type, and is individually installed in a double sealed polyethylene bag. It is worth mentioning that because siloxane is thermosetting, they can not be reprocessed like thermoplastics. For the same reason, they can't be hot sealed; therefore, the silica gel sleeve is attached to the hose reversal joint and is fastened in the opposite direction with two ligature bands, and the hose is fixed. Co molding is feasible and sometimes used in the field of medical devices.


硅胶管外观和机械功用


Appearance and mechanical properties of silica gel tube


与一些有机热塑性塑料相比,有机硅的透明 度最好形貌 为“半透明 ”。这一效果 是因为 制造 软管的有机硅弹性体由有机硅聚合物和无定形二氧化硅组成。因为 这两种质料具有分别 的折射率,而且没有特定混合理 来使它们相配,是以 一切 硅胶管都是半透明 的。


Compared with some organic thermoplastic, the transparency of silicone is best described as "translucent". The result is that silicone elastomers for making hoses consist of silicone polymers and amorphous silica. Because the two materials have different refractive indices and there is no specific mixing method to match them, all silicone tubes are translucent.


硅胶管固化后,有机硅弹性体表现 出故意 旨 的机械功用 ,这征求 中等硬度和高断裂伸长率,但拉伸强度比聚氨酯(PU)低。与聚四氟乙烯(PTFE)相比,它们具有发粘的外貌和较高的摩擦系数,但刚性要小得多。因为 具有疏水性而且是良好 的电绝缘体,以是 它们会吸引灰尘。它们的事情温度规模比聚氯乙烯(PVC)更大。


After the silicone tube was solidified, the organosilicon elastomer showed significant mechanical properties, which included medium hardness and high elongation at break, but the tensile strength was lower than that of polyurethane (PU). Compared with polytetrafluoroethylene (PTFE), they have visbreaking surfaces and higher friction coefficient, but the rigidity is much smaller. Because they are hydrophobic and are excellent electrical insulators, they attract dust. Their working temperature range is larger than that of PVC (PVC).
