Poliamid tolalar \u2014 poli- amidlar eritmasidan tayyorlanadigan sintetik tolalar P.t. olish uchun, odat- da, mol. m. 15000 dan 30000 gacha bo’lgan chi-ziqsimon poliamidlardan foyda- laniladi. P.t. pishiq, juda qayishoq, eyilmaydi, ko’pgina kimyoviy moddalar ta’siriga chidamli, o’ziga bo’yoq oladi. Kontsentrlangan mineral kislotalarda (ayniqsa, qaynatilganda), fenol, krezol va b.da eriydi. Bir xil tolalar termo- oksidlanishga, yorug’lik-ka, ayniqsa, ul- trabinafsha nurlarga chidamsiz; bu kam- chiliklarni bartaraf qilish maqsadida poliamidga turli mikroqo’shimchalar (turli metall tuzlari, aromatik amin- lar va h.k.) qo’shiladi. P.t.ni tayyorlash texnologik ja-rayoni 3 bosqichdan: po- limerii sintez qilish, tolani shakllan- tirish va ishlov berishdan iborat. P.t. ning quyidagi turlari bor: Poligek- sameti-lenadipinamid tolasi \u2014 anid (MDH mamlakatlari), naylon (AQSh), perlon, dederon (GFR), maranil, luron (Angliya). Poli \u2014e\u2014kaproa-Mid tolasi \u2014 kapron (MDH mamlakatlari), neylon, kaprolon (AQSh), perlon (GFR), Silon (Chexiya), Amilan (Yaponiya), akulon (gol- landiya), grilon (Shveytsariya), Pol i – w – ena ntoa-Mid tolasi \u2014 enant (MDH mamlakatlari), naylon (AQSh). Poli-sh- undekanamid tolasi \u2014 undekan (MDH mamlakatlari), naylon (AQSh), rolsin (Angliya), rilsan (Frantsiya, Italiya). P.t. uzluksiz ip va shtapel tola xrlida chiqariladi.<\/p>\n","protected":false},"excerpt":{"rendered":"
