Yini ulwelwesi lwe-pla polyvinyl fiber fiber

February 18, 2024

I-Polyvinyl Alcohol (PVA) ingenye yama-polymers aguquguqukayo ahlukahlukene kakhulu, i-PVA ingancishiswa ngokushesha ngamanzi ukwakha i-colloid ezinzile, ukusebenza phakathi kwamapulasitiki nemikhiqizo . I-Polyvinyl Alcohol Fiber iyinye yezinhlobo ezibalulekile zezinhlobo zokwenziwa, futhi umkhiqizo wawo ojwayelekile uyi-polyvinyl accoholdehyde fiber, okubhekiselwa kuzo njenge-vinylon noma i-vinylon eChina. Imikhiqizo ikakhulukazi imicu emifushane.

I-Polyvinyl Alcohol Fibre isetshenziselwa ngokuxutshwa ngokotini, okufakwe kwizindwangu zekotini ezahlukahlukene. Ngaphezu kwalokho, ingahlanganiswa neminye imicu noma ukuphonswa okumsulwa, ukuluka zonke izinhlobo zezindwangu ezilukiwe noma ezihlanganisiwe. Ukusebenza nokubukeka kwe-polyvinyl alcohol Filament kufana kakhulu nalokho kwama-silkworms emvelo, futhi kungasetshenziswa ukuze kufakwe izindwangu ze-satin. Kodwa-ke, ngenxa yokuqina kwayo okumpofu, akulula ukudaya, ngakho-ke angenziwa ngezingubo ezisezingeni eliphakeme. Eminyakeni yamuva nje, ukuthuthukiswa kwe-polyvinyl alcohole Production Technology, isicelo sayo embonini, ezolimo, ezokudoba, ukuthutha nokunye ukwanda.

Utshwala obujwayelekile be-polyvinyl buneziqu eziphakeme ze-polymerization kanye ne-adforkysis, ku-chain main eyinhloko equkethe inani elikhulu le-hydroxyl, ukwakheka kwenhlangano enkulu, amaphuzu aphakathi nendawo, okuholela ku-polyvinyl fibers ephakeme I-Crystaltaltity, ayilungele ukungena kwama-molecule wamanzi. Uma uthuthukisa i-soubility yamanzi kumele buthaka ubumbano phakathi kwama-macromolecule, kunezindlela ezimbili ezijwayelekile: ukunciphisa okuqukethwe kwe-hydroxy futhi kwandise ibanga phakathi kweqembu le-hydroxyl.

Utshwala be-polyvinyl ngokwanda kwe-degree of polymerization, i-fiber hydrophobicicity inyuka, izinga lokushisa lamanzi le-solubity likhuphuka ngokufanele. Ngakho-ke, ukusetshenziswa kwezinga eliphansi le-polymerization we-polyvinyl alcohol yokuxubha, kungathola izinga lokushisa lamanzi anciphile lefayibha. Kodwa-ke, iziqu ze-polymerization ziyancipha, ukuphothulwa kuba kubi kakhulu. Amalungelo obunikazi aseJapan asebenzisa iziqu ze-polymerization eziphansi (ezingaphansi kwama-800) kanye nezinto eziphakeme ze-polymerization (ezingaphezu kuka-1000) izingxenye zokuxubana, okuholela kwe-fiber spinning kanye ne-soubelity yamanzi kulungile.

Izinga le-adffolcollisn of polyvinyl Alcohol libuye libe nethonya elikhulu ekuhlanzeni kwamanzi kwemicu. Iqembu le-ethylcool elisele lizovimbela ukuhlelwa okusondele kuma-macromolekyuli, ukuze ikristaluna libe mpofu, futhi izinga lokushisa lamanzi lizokwehliswa. Kodwa-ke, ukuba khona kweqembu le-ethylcools asele kuzothinta izakhiwo ezishubile zemicu emikhulu futhi kwandise inani lama-fibula aphukile kanye nemibala yezinwele, ngakho-ke kuzothinta imibala ye-FIBLERS, ngakho-ke, i-degree of adfy soluble alcohol kufanele ibe yi izinga elifanele.
