Cov kuab tshuaj siv rau qhuav gel spinning yog feem ntau decalin nrog qis boiling point, siab volatility thiab zoo solubility rau UHMWPE.UHMWPE thiab decalin yog tov rau hauv ib qho kev daws teeb meem uas tsis muaj ntau tshaj 10% nyob rau hauv ib tug ntxaib-ntsia hlau extruder, thiab ces extruded los ntawm ib tug spinneret kom nkag mus rau ib tug rhuab nitrogen passage kom tshem tawm cov kuab tshuaj.Tom qab txias, qhuav gel filaments yog tsim, thiab ces UHMWPE fibers yog tsim los ntawm ntau theem siab zog kub stretching.Cov txheej txheem qhuav gel spinning yog technically nyuaj thiab yuav tsum muaj kev sib khi siab ntawm cov txheej txheem rov qab, tab sis nws qhov zoo feem ntau nyob hauv:
1. Cov txheej txheem luv dua, kev tsim khoom ntau dua thiab tus nqi qis dua.
2. Cov kuab tshuaj tuaj yeem siv ncaj qha, uas yog qhov tsim nyog rau kev tiv thaiv ib puag ncig.
3. Nyob rau tib lub sijhawm, cov fibers npaj los ntawm txoj kev qhuav muaj crystallinity ntau dua, txhua yam khoom, fiber ntau ntom thiab zoo thermal stability.
4. Nws muaj luster zoo, muag muag thiab tsis tshua muaj kuab lom residue, thiab tsim nyog rau kev kho mob thiab tsev textile teb.Tam sim no, cov tuam txhab tseem ceeb yog DSM Lub Tuam Txhab ntawm Netherlands, TOYOBO Lub Tuam Txhab ntawm Nyiv, thiab Yizheng Chemical Fiber Company ntawm Sinopec.
Nyob rau hauv cov txheej txheem ntub dej spinning, cov roj dawb uas muaj qhov kub kub thiab qhov tsis muaj zog yog siv los ua cov kuab tshuaj.Ultrahigh hmoov yog yaj nyob rau hauv cov roj dawb los ua spinning Tshuag tov.Tom qab ntawd, nws yog extruded rau hauv cov kua filament los ntawm spinning Cheebtsam.Tom qab ntawd, nws yog txias nyob rau hauv ib da dej da dej los tsim ib tug gel filament.Cov gel filament yog muab rho tawm, qhuav thiab desolvated los tsim ib qho kev tsis sib haum xeeb ua ntej, thiab tom qab ntawd nws yog kub ncab rau ob peb zaug kom ua tiav fiber ntau.Cov txheej txheem ntub dej tsis yooj yim thiab xav tau cov cuab yeej siv tsawg.Tam sim no, feem ntau cov lag luam hauv tsev tau txais cov txheej txheem ntub dej, uas tuaj yeem tsim cov khoom siv tub rog thiab pej xeem fiber ntau nrog cov lej sib txawv thiab muaj zog.Txawm li cas los xij, lub hom phiaj ntawm cov txheej txheem ntub dej tam sim no txoj kev tshawb fawb yog txhawm rau txhim kho cov txheej txheem uas twb muaj lawm, txuas ntxiv txhim kho cov khoom siv hluav taws xob, kev ruaj ntseg thiab kev ua haujlwm ntawm fiber ntau, tsom rau cov khoom nruab nrab thiab qis kawg.Tam sim no, cov tuam txhab tseem ceeb yog Honeywell Company hauv Tebchaws Meskas, Beijing Tongyizhong Tuam Txhab hauv Suav teb, thiab Nantong Jiujiujiu Company.
