Qhov Sawv Thiab Txhim Kho Ntawm Pvc Yas Profiles
May 20, 2022
Cov qhov rais yas tau siv rau ntau xyoo lawm, tab sis cov yas siv los ua cov yas yas yog yuav luag txhua qhov tawv PVC, thiab cov profiles yuav luag dawb.
Nrog rau kev loj hlob ntawm qhov rais profile PVC yas profiles, cov neeg siv khoom tsis txaus siab rau cov ntaub ntawv dawb yooj yim, tshwj xeeb tshaj yog PVC nws tus kheej muaj qhov kub thiab txias tsis kam, tshwj tsis yog qhov sib ntxiv ntawm titanium dioxide los tiv thaiv ib qho loj ntawm ultraviolet dawb, lwm yam xim profile Nws yog. Nws yooj yim rau fading thiab discoloration. Tib neeg tau tsim cov yas yas tshiab. Txawm hais tias muaj ntau yam yas yas siv tau los tsim cov profiles, tus nqi nyuaj rau kev sib tw.
Lub pvc yas profile yog hloov kho, thiab polypropylene kuj tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm qhov rais profile. Cov khoom siv polypropylene raw khoom siv rau cov khoom siv profile yog ib qho tshiab high-branched block copolymer, uas feem ntau yog formulated nrog ib tug stabilizer, ib tug colorant, ib tug reinforcing neeg sawv cev thiab lwm yam. Lawv tsis tsuas yog ua tau raws li qhov yuav tsum tau ua, tab sis kuj yog cov txheej txheem extrusion profile. Lub hauv paus cob rau qhov rais profiles yog ib tiam tshiab ntawm cov khoom siv polypropylene xws li siab rigidity, siab yaj lub zog, thiab ethylene thaiv copolymer. Cov khoom no muaj kev cuam tshuam lub zog, rigidity thiab kub tsis kam thiab raug hloov kho los ntawm kev siv qee cov khoom ntxiv. Nws tuaj yeem ua kom muaj tshuaj lom neeg ntau dua thiab kev ntxhov siab tawg ua haujlwm.
