Description

(54) СПОСОБ УПРОЧНЕНИЯ ЗАКАЛЕННЫХ СТЕКЛЯННЫХ ИЗДЕЛИЙ(54) METHOD OF STRENGTHENING TEMPERED GLASS PRODUCTS

Изобретение относитс  к производству изделий из стекла, преимущественно изол торов, и может найти применение при производстве высоковольт ных изол торов. В св зи с использованием высоковольтных стекл нных изол торов в районах с тропическим влажным климатом важным фактором  вл етс  устойчивость поверхности стек лодетали- к воздействию, влажной атмосферы и загр знени м, котора  может быть обеспечена путем ее гидрофобизации . Известен способ упрочнени  поверх ности стекла путем нанесени  гидрофобной пленки полиэтилсилоксановых и полиметилсилоксановых жидкостей 1. Наиболее близким по технической сущности и достигаемому результату к изобретению  вл етс  способ упрочнени  закаленных стекл нных изделий, преимущественно изол торов, путем нанесени  гидрофобной пленки из раст вора кремнийорганических жидкостей, органических масел, воды при 80150°С в течение 2-4 мин 2. Цель изобретени  - повышение качества пленки. Это достигаетс  тем, что пленку нанос т из смеси полиэтилсилоксановой и полиметилсилоксановой жидкостей в соотношении от 1:1 до 1:1,04, а термообработку ведут при 125-135 С, Нагретое до 720-800 С изделие устанавливают в закалочную машину, где его подвергают резкому охлаждению. По истечении 3-5 мин изделие устангшливаетс  на с.етку печи термоиспытаний , где происходит релаксаци  закалочных напр жений. После этого изделие , охлажденное до 140°С, поступает в ванну отрицательного термоудара, заполненную водой при 25±5°С, где изделие выдерживают 3-5 мин. Затем изделие поступает в ванну положительного термоудара, заполненную смесью полиэтилсилоксановой (ПЭС-4) и полиметилсилоксановой (ПМС-200) жидкост ми в соотношении 1:1, и нагреваетс  до 130С в течение 3-5 мин. В результате перемещени  издели  (изол тора ) по ванне положительного термоудара его поверхность покрываетс  гидрофобной пленкой, повышающей прочность и срок службы изол тора. Использование предлагаемого способа обеспечивает устойчивость СТРК- .. ,The invention relates to the manufacture of glass products, mainly insulators, and may find application in the manufacture of high voltage insulators. In connection with the use of high-voltage glass insulators in areas with tropical humid climates, an important factor is the stability of the surface of the glass to the details of exposure, the humid atmosphere and pollution that can be provided by its hydrophobization. The known method of hardening the glass surface by applying a hydrophobic film of polyethylsiloxane and polymethylsiloxane liquids 1. The closest to the technical essence and the achieved result of the invention is a method of hardening hardened glass products, mainly insulators, by applying a hydrophobic film from a solution of silicone fluids, organic oils, water at 80150 ° C for 2-4 min. 2. The purpose of the invention is to improve the quality of the film. This is achieved by the fact that the film is applied from a mixture of polyethylsiloxane and polymethylsiloxane liquids in a ratio of from 1: 1 to 1: 1.04, and the heat treatment is carried out at 125-135 ° C. The product heated to 720-800 ° C is installed in a quenching machine, where its subjected to rapid cooling. After 3-5 minutes, the product is installed on the grid of the heat-test furnace, where the quenching stresses relax. After this, the product, cooled to 140 ° C, enters the negative thermal shock bath filled with water at 25 ± 5 ° C, where the product is held for 3-5 minutes. The product then enters a positive thermal shock bath filled with a mixture of polyethylsiloxane (PES-4) and polymethylsiloxane (PMS-200) liquids in a 1: 1 ratio, and is heated to 130 ° C for 3-5 minutes. As a result of the movement of the product (insulator) in a bath of positive thermal shock, its surface is covered with a hydrophobic film, which increases the strength and service life of the insulator. The use of the proposed method ensures the stability of the system.,
