PVC VS PTFE

Ptfe yog dab tsi?

Polytetrafluoroethylene (PTFE) yog ib qho hluavtaws fluoropolymer ntawm tetrafluoroethylene thiab yog PFAS uas muaj ntau daim ntawv thov.PTFE cov tshuaj tseem ceeb, qhov kub thiab txias, noo noo, thiab hluav taws xob tiv thaiv ua rau nws yog ib qho khoom siv zoo tshaj plaws thaum twg cov khoom, cov cuab yeej, thiab cov khoom yuav tsum tau ua kom ruaj thiab txhim khu kev qha txawm tias cov ntawv siv zog tshaj plaws.Nyob rau saum toj no, PTFE boasts tshwj xeeb uas tsis muaj-kub durability thiab hluav taws kub tsis kam uas ua rau nws ib tug zoo xaiv rau ib tug tas li loj hlob daim ntawv teev cov khoom, Cheebtsam, thiab daim ntaub ntawv.

PVC yog dab tsi?

PVCyog lub ntiaj teb thib peb-feem ntau cov khoom siv hluavtaws polymer ntawm cov yas (tom qab polyethylene thiab polypropylene). Kwv yees li 40 lab tons ntawm PVC yog tsim txhua xyoo.

PVC tuaj nyob rau hauv nruj (qee zaum abbreviated li RPVC) thiab hloov tau cov ntaub ntawv.Rigid PVC yog siv los tsim cov yeeb nkab, qhov rooj thiab qhov rais.Nws kuj yog siv los ua lub raj mis yas, ntim khoom, thiab cov txhab nyiaj lossis daim npav ua tswv cuab.Ntxiv plasticizers ua rau PVC softer thiab saj zawg zog.Nws yog siv nyob rau hauv cov kav dej, hluav taws xob cable rwb thaiv tsev, flooring, signage, phonograph records, inflatable products, thiab nyob rau hauv cov roj hmab hloov.Nrog paj rwb los yog linen, nws yog siv nyob rau hauv zus tau tej cov canvas.
