PVC yog ib qho ntawm cov yas siv ntau tshaj plaws hauv kev lag luam. Plasticol, lub tuam txhab Italian nyob ze Varese tau tsim PVC granules rau ntau tshaj 50 xyoo tam sim no thiab cov kev paub ntau xyoo tau tso cai rau kev lag luam kom tau txais kev paub tob tob uas peb tam sim no siv tau los ua kom txaus siab rau txhua tus neeg siv khoom. ' thov muab cov khoom tshiab thiab txhim khu kev qha.
Qhov tseeb tias PVC yog dav siv rau kev tsim ntau yam khoom sib txawv qhia tau hais tias nws cov yam ntxwv zoo li cas yog qhov tseem ceeb thiab tshwj xeeb. Cia peb pib tham txog qhov rigidity ntawm PVC: cov khoom yog nruj heev yog tias ntshiab tab sis nws yuav hloov tau yog tias tov nrog lwm yam khoom. Qhov kev sib txawv no ua rau PVC haum rau kev tsim cov khoom siv hauv ntau qhov chaw, los ntawm lub tsev mus rau lub tsheb.
Txawm li cas los xij, tsis yog txhua qhov peculiarity ntawm cov khoom yog yooj yim. Lub melting kub ntawm no polymer yog heev tsawg, uas ua rau PVC tsis haum rau cov cheeb tsam uas tsis tshua muaj kub kub mus txog.
Ntxiv mus, kev phom sij tuaj yeem tshwm sim los ntawm qhov tseeb tias, yog tias kub dhau, PVC tso tawm cov tshuaj chlorine li hydrochloric acid lossis dioxin. Kev sib cuag nrog cov khoom no tuaj yeem ua rau muaj teeb meem kev noj qab haus huv uas tsis tuaj yeem kho.
Ua kom cov polymer sib haum nrog nws cov khoom lag luam, nws yog tov nrog stabilizers, plasticisers, colorants, thiab lubricants uas pab nyob rau hauv lub manufacturing txheej txheem raws li zoo raws li nyob rau hauv ua PVC ntau pliable thiab tsis tshua muaj hnav thiab tsim kua muag.
Raws li nws cov yam ntxwv thiab nws qhov txaus ntshai, PVC granules yuav tsum tau tsim nyob rau hauv cov nroj tsuag tshwj xeeb. Plasticol muaj cov kab ntau lawm nkaus xwb rau cov khoom siv yas no.
Thawj theem ntawm kev tsim khoom ntawm PVC granules yog tsim los ntawm cov raj ntev ntawm cov khoom tsim los ntawm cov nroj tsuag tshwj xeeb extrusion. Cov kauj ruam tom ntej yog txiav cov yas hauv cov hlaws me me tiag tiag. Cov txheej txheem yog qhov yooj yim tiag tiag, tab sis nws tseem ceeb heev uas yuav tsum tau siv ceev faj thaum tuav cov khoom, ua tib zoo ceev faj uas yuav ua rau nws nyuaj.
