Ishqalanish materiallari uchun yopishtiruvchi moddalar nima?
All media materials that can connect the same or different types of materials together are called adhesives, also known as adhesives. It is an old and young science. The so-called "old" refers to the fact that thousands of years ago, humans began to use natural polymers such as animal glue and vegetable glue to bond products and production tools. Until the beginning of the last century, due to the appearance of various synthetic resins and synthetic rubbers, especially the successful production and commercialization of some representative polymers such as phenolic resin, epoxy resin, chloroprene rubber, nitrile rubber, etc., modern adhesives have The comprehensive properties of high strength, durability, and outstanding heat resistance have developed rapidly.
Ishqalanish materialining yopishtiruvchisi bilan hosil bo'lgan asosiy tizim qatron turi, rezina turi va qatron va kauchukning kompozit turidir. Ko'pgina yopishtiruvchi moddalar polimer materiallardan tayyorlanadi, ularning ba'zilari kimyoviy reaktsiyalar yoki fizik ta'sirlar orqali davolanishni yakunlash uchun ba'zi erituvchilar qo'shilishi kerak va yopishtiruvchi moddalarni saqlash vaqtida qattiqlashuv sekin sodir bo'ladi. Shuning uchun, yopishtiruvchi ma'lum bir saqlash muddatiga ega, bu namlik, harorat, ventilyatsiya va boshqalar kabi saqlash sharoitlari bilan bog'liq. Belgilangan vaqt ichida yopishqoqning ishlashi asosan o'zgarmasligini ta'minlash uchun yopishtiruvchiga yopishish usuliga katta e'tibor berish kerak. Har xil turdagi yopishtiruvchi moddalar turli xil xususiyatlarga ega bo'lganligi sababli turli xil saqlash sharoitlariga ega.
