Subject: PVC pipe hostalite tech. собсна сабж.контекста как такового нет. Встретилось в руководстве по техническому обслуживанию дверей на фотоэлементах (Gatemaster GM9)в перечне того, что включено в комплектацию. Есть картинка, на которой изображена полая трубка непонятно какого размера. |
| поливинилхлорид. |

с пластизолем: ---------- the plastic material utilized is a polyvinyl chloride which lends itself particularly well to the formation of mixtures with plasticizers. These mixtures are commonly called "Plastisol". the Plastisol is a liquid characterized by a certain viscosity which is greater when the content of the plasticizers is smaller. When the Plastisol is heated, the viscosity at first decreases (at a temperature of 40.degree.-50.degree. C.) then at about 60.degree. there is a very rapid increase of the viscosity and the mass becomes solid, attaining a stage called "pre-gelatinization". The compact mass thus obtained is friable and has a very low mechanical strength. When the heating is continued to about 180.degree.-200.degree. C. there is abtained a complete "gelatinization" and after cooling it results in a material resembling rubber which is insensible to water, aqueous solutions, acids and alkalies, alcohol and hydrocarbons. This material is characterized by a very high mechanical strength and the Shore hardness of the final product is a function of the type and the quantity of the plasticizer used. For covering wiping cylinders for use with water, there is used a Plastisol, the characteristics of which permit obtaining not only a good coating (for which the viscosity should not be too high) but also the desired qualities of the final product (hardness, mechanical strength, characteristics of the coating, etc.). The products used to obtain this effect are as follows: 1. Polyvinyl Chloride (PVC): "Hostalite P/VP-3475" made by Hoechst AG Frankfort, West Germany. This is a white powder obtained by the polymerization in emulsion of vinyl chloride. The form and size of the molecules are such as to provide very fluid Plastisol. While the powder is not hygrascopic, it is advisable to store it in closed vessels. |

получается тогда: поливинилхлоридная хосталитная трубка? |

Посмотрите: www.proz.com/kudoz/1167527 - 32k получается так: трубка (труба) из поливинилхлоридного материала "Хосталит" (или "Hostalite") |
