1. Txhim kho kev ua haujlwm ntawm cov khoom siv: Cov khoom siv pab ua cov khoom siv PVC tuaj yeem txhawb kev yaj cov resin zoo dua, txhim kho cov khoom siv rheological ntawm cov khoom yaj, thiab muab cov haujlwm lubrication. Qhov no pab txo cov teeb meem xws li kev tawg ntawm cov khoom yaj thiab qhov roughness ntawm qhov chaw, ua rau cov txheej txheem machining du dua.
2. Txhim kho kev ua haujlwm ntawm cov khoom: Cov khoom siv pab ua PVC tuaj yeem txhim kho cov khoom siv kho tshuab, kev ua haujlwm, thiab kev tiv taus cua sov thiab txias ntawm cov khoom PVC. Piv txwv li, cov khoom ntxiv tshwj xeeb rau kev ua cov ntaub ntawv PVC tuaj yeem txhim kho cov ntsuas xws li lub zog tensile, elongation thaum tawg, lub zog khoov, thiab lub zog cuam tshuam yooj yim, thaum txo qhov kev puas tsuaj ntawm kev cuam tshuam rau rab rauj.
3. Txo nqi: Los ntawm kev hloov qee cov resins, cov khoom siv ua PVC tuaj yeem txo cov nqi khoom siv raw. Piv txwv li, tus nqi ntawm cov khoom siv tshwj xeeb rau kev ua cov ntaub ntawv PVC tuaj yeem txo tau los ntawm 150-260 yuan ib tuj.
4. Txhim kho qhov ci ntsa iab ntawm qhov chaw: Cov tshuaj ntxiv no kuj tseem tuaj yeem txhim kho qhov ci ntsa iab ntawm qhov chaw thiab qhov ci ntawm cov PVC profiles, txhim kho qhov ruaj khov ntawm qhov ntev, thiab ua rau qhov kub ntawm Vicat mos dua.
5. Txhim kho kev sib raug zoo thiab kev sib kis tau zoo: Cov khoom siv ua PVC muaj kev sib raug zoo nrog PVC resin, yooj yim rau kev sib kis, thiab yooj yim rau kev siv. Qhov no pab tswj cov khoom siv zoo dua thaum lub sijhawm ua haujlwm.
6. Cov Haujlwm Tshwj Xeeb: Los ntawm kev ntxiv cov khoom siv tshwj xeeb, cov khoom siv ua tiav PVC tuaj yeem ua rau cov ntaub ntawv PVC muaj cov haujlwm tshwj xeeb xws li hluav taws kub hnyiab, tiv thaiv hluav taws xob, tiv thaiv kab mob, thiab lwm yam, kom tau raws li qhov xav tau ntawm ntau qhov chaw sib txawv.
