Chii chinonzi Ptfe?
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer ye tetrafluoroethylene uye iri PFAS ine akawanda maapplication.PTFE's yakakosha kemikari, tembiricha, mwando, uye magetsi kuramba anoita kuti ive chinhu chakakodzera pese apo zvigadzirwa, maturusi, uye zvikamu zvinoda kugara uye kuvimbika mune kunyangwe zvikumbiro zvinonetsa.Pamusoro peizvi, PTFE inozvirumbidza yakasarudzika yakadzika-tembiricha kusimba uye kuramba moto izvo zvinoita kuti ive sarudzo yakanaka kune inogara ichikura runyorwa rwezvigadzirwa, zvikamu, uye maapplication.
Chii chinonzi PVC?
PVCndiyo yechitatu-inonyanya kugadzirwa pasirese polima yepurasitiki (mushure me polyethylene uye polypropylene) .Angangoita mamiriyoni makumi mana ematani ePVC anogadzirwa gore rega rega.
PVC inouya yakasimba (dzimwe nguva yakapfupikiswa seRPVC) uye inochinjika mafomu.Rigid PVC inoshandiswa pakuvaka pombi, magonhi nemahwindo.Inoshandiswawo mukugadzira mabhodhoro epurasitiki, kurongedza, uye makadhi ekubhengi kana enhengo.Kuwedzera mapurasitiki anoita kuti PVC ipfave uye iwedzere kushanduka.Inoshandiswa mukugadzira pombi dzemvura, magetsi ekudzivirira tambo, pasi, zvikwangwani, marekodhi egiramufomu, zvigadzirwa zvinoputika, uye mune zvinotsiva rabha.Nekotoni kana yerineni, inoshandiswa mukugadzira canvas.
