Thaum nws los txog rau tus kheej-nplaum cov ntawv cim, txhua tus yuav tsum xub xav ntawm tus tsiaj thiab PVC, tab sis koj paub ntau npaum li cas txog cov tsiaj thiab PVC? Niaj hnub no, cia kuv qhia koj:
Qhov txawv 1
Lub raw khoom puab yog txawv:
PVC, uas yog, polyvinyl chloride, cov xim qub yog cov nyom me ntsis thiab ci ntsa iab.
Tus tsiaj, uas yog, polyethylene terephthalate, muaj kev pom tseeb zoo heev.
Lub zog ntawm cov ntaub ntawv raw yog txawv:
PVC, uas yog, polyvinyl chloride, muaj cov clarity zoo dua li highSetylene siab thiab polystyrene, tab sis phem tshaj polyethylene, tab sis phem tshaj polyethylene. Nws tau muab faib ua cov mos mos thiab tawv polyvinyl chloride raws li qhov sib txawv ntawm cov hloov kho. Cov khoom muag muag muag yog mos thiab tawv, thiab hnov zoo li nplaum. Lub zog ntawm cov khoom tawv yog siab dua li ntawm cov qes qis-siab polyethylene, tab sis qis dua li cov polypropylene, thiab cov ris tsho ntxuav hniav yuav tshwm sim ntawm khoov.
Tus tsiaj, uas yog, polyethylene terephthalate, muaj zoo dua compressive compressive zog thiab ductility tshaj polyethylene thiab polyvinyl chloride, thiab tsis yooj yim tawg.
Lub USES ntawm cov khoom siv raw sib txawv:
PVC, uas yog, cov khoom lag luam ntawm polyvinyl chloride: Cov laug cam, cov khoom siv khau, cov khoom ua si, cov tawv nqaij, cov khoom sib xyaw, thiab lwm yam, thiab lwm yam.
Tus Tsiaj, Uas Yog, Cov Ntawv Siv Ntawm Polyethylene Terephthalate: Nws feem ntau tau txais cov khoom siv dej kub, siv rau cov khoom siv hauv chav dej, cov khoom lag luam tawv nqaij, khoom siv rau cov tawv nqaij Khoom siv, khoom siv txhua yam, thiab lwm yam.
Qhov txawv 2
1. PVC tsis yog siv tau, tab sis tus tsiaj siv rov ua dua tshiab;
2. Yog tias koj siv tus tsiaj fwj thiab pvc lo lus, koj yuav tsum tau tshem tawm cov ntawv PVC recycling lub fwj; Thaum cov tsiaj cov ntawv tsis tas yuav raug tshem tawm;
3. Tus tsiaj muaj cov khoom Dielectric zoo heev, nrog kev tawm tsam zoo, tiv thaiv kev kos, kub tsis kam thiab lwm yam khoom;
4. PVC thiab tus tsiaj muaj cov khoom zoo sib xws. Nws muaj qhov hloov tau zoo dua thiab softer zoo dua li tus tsiaj, tab sis PVC muaj cov tsis zoo thiab muaj kev tiv thaiv tsis zoo rau kev tiv thaiv ib puag ncig.
5. Tsiaj feem ntau muaj tus tsiaj dawb lossis pob tshab tooj, thiab tseem tuaj yeem ua rau hauv ib qho kub lossis nyiaj zoo nkauj heev.
6. Tsiaj ntawv sau muaj cov khoom siv zoo, muaj zog cuam tshuam, cov roj tsis kam thiab rog tsis kam. Cov ntawv nplaum kub thiab qis dua yog tseem muaj zog dua ntau cov plastics, yog li chav ua mov phaj peb feem ntau pom yog cov tsiaj + txhuas ntawv ci.
7. Cov khoom tsiaj muaj cov khoom zoo transparency thiab kev softness hauv qab no 25u. Nws yog tsuas yog siv rau lub tsheb kauj vab thiab maus taus txiav txim siab thiab qee cov khoom lag luam hluav taws xob cov khoom lag luam. Dawb Tsiaj yog tsuas yog siv nyob rau hauv xov tooj ntawm tes xov tooj roj teeb, thiab lwm yam.
8. Lub ntsiab sib txawv ntawm PVC yog tias nws muaj tsis zoo thermal stability thiab yog yooj yim laus los ntawm lub teeb, kub thiab oxygen. Tsis tas li ntawd, ntau cov tshuaj lom neeg ntxiv feem ntau ntxiv rau hauv PVC tsim kev lag luam.
Qhov txawv 3
Tus tsiaj: nyuaj, tawv, siab lub zog, ci saum npoo av, ib puag ncig zoo, pob tshab thiab cov xim muaj xim. Qhov tsis zoo yog tias tus tsiaj high-zaus ua kom sov kub yog qhov nyuaj dua thiab tus nqi yog qhov kim dua pvc. Cov ntaub ntawv no feem ntau hloov los ntawm PVC los ntawm cov neeg siv uas xav tau cov khoom lag luam zoo thiab kev tiv thaiv ib puag ncig. Cov ntaub ntawv tsiaj feem ntau siv los ua cov hwj yas, ntim cov thawv ntim khoom, thiab lwm yam.
PVC: Cov khoom siv sib xyaw ua ke uas yog muag muag, tawv, thiab yas. Nws tuaj yeem ua pob tshab thiab hauv ntau yam xim. Pob tshab PVC feem ntau siv rau pob hluav taws xob, cov tshuaj pleev ib ce, cov khoom ua si, khoom plig, thiab lwm yam khoom.
