Intshayelelo kwi-UHMWPE ifayibha iinkqubo ezomileyo nezimanzi

I-solvent esetyenziselwa ijeli eyomileyo ijikeleza ngokubanzi i-decalin kunye neqondo eliphantsi lokubila, ukuguquguquka okuphezulu kunye nokunyibilika okulungileyo kwe-UHMWPE.I-UHMWPE kunye ne-decalin zixutywe kwisisombululo kunye nogxininiso olungekho ngaphezu kwe-10% kwi-twin-screw extruder, kwaye emva koko ikhutshwe nge-spinneret yokungena kwi-nitrogen passage evuthayo yokususa i-solvents.Emva kokupholisa, imicu yejeli eyomileyo iye yenziwa, emva koko iintsinga ze-UHMWPE zenziwe ngamanqanaba amaninzi aphezulu ashushu asolula.Inkqubo eyomileyo yokusonta ijeli inzima ngokobuchwephesha kwaye ifuna ukutywinwa okuphezulu kwenkqubo yokubuyisela, kodwa izibonelelo zayo ikakhulu zilele koku:

1. Inkqubo emfutshane, imveliso ephezulu kunye neendleko eziphantsi.

2. I-solvent inokuthi ihlaziywe ngokuthe ngqo, eyenza ngakumbi ukukhuselwa kwendalo.

3. Ngaphantsi kwezinye iimeko ezifanayo, iifayili ezilungiselelwe ngendlela eyomileyo zinekristallini ephezulu, iipropathi zomatshini, ubuninzi be-fiber kunye nokuzinza okungcono kwe-thermal.

4. Inokukhanya okulungileyo, imvakalelo ethambileyo kunye nentsalela ye-solvent ephantsi, kwaye ifanelekile kwimihlaba yonyango kunye nempahla yasekhaya.Okwangoku, abavelisi abaphambili yiNkampani yeDSM yaseNetherlands, iTOYOBO Inkampani yaseJapan, kunye neYizheng Chemical Fiber Company yaseSinopec.

Kwinkqubo yokuvelisa ukujikeleza okumanzi, ioli emhlophe enendawo yokubilisa ephezulu kunye nokuguquguquka okuphantsi kusetyenziswa njenge-solvent.I-Ultrahigh powder inyibilika kwioli emhlophe ukwenza isisombululo sesitokhwe esijikelezayo.Emva koko, ikhutshelwa kwi-filament engamanzi ngamacandelo ajikelezayo.Emva koko, ipholiswe kwindawo yokuhlambela amanzi ukuze yenze i-gel filament.I-gel filament ikhutshwe, yomiswe kwaye ihlanjululwe ukuze yenze i-precursor engabonakaliyo, kwaye ishushu yolulwe amaxesha amaninzi ukwenza i-fiber egqityiweyo.Iteknoloji yenkqubo emanzi ayinzima kakhulu kwaye idinga izixhobo ezincinci.Okwangoku, uninzi lwamashishini asekhaya amkela inkqubo yokusonta emanzi, enokuvelisa iimveliso zomkhosi kunye nezoluntu ezinamanani ahlukeneyo okuphika kunye namandla.Nangona kunjalo, ugxininiso lophando lwendlela yenkqubo emanzi yangoku kukuphucula indlela yenkqubo ekhoyo, ukuphucula ngakumbi iimpawu zemishini, ukuzinza kunye nokusebenza kwefiber, kugxininise kwimveliso ephakathi kunye nesezantsi.Okwangoku, abavelisi abaphambili yiNkampani yeHoneywell eMelika, iBeijing Tongyizhong Company eTshayina, kunye neNantong Jiujiujiu Company.
