Nzira yekusiyanisa sei pfungwa yekusava nehutu uye kuchengetedza kwezvakatipoteredza kwePVC plastiki hose

Vatengi vazhinji havana kujeka nezve pfungwa dzekusa-chepfu uye kuchengetedzwa kwezvakatipoteredza kwePVC epurasitiki hoses, uye vanofunga kuti isiri-chepfu inoenderana nenharaunda.Kutaura zvazviri, hazvisizvo.Kuti tinzwisise zvakadzama pfungwa mbiri idzi, tinofanira kutanga tasiyanisa zvinhu zvakasvibiswa uye kushandiswa kwepombi.
Kuiswa kwePVC epurasitiki hose ndeyekushumira veruzhinji uye kuishandisa muhupenyu hwevanhu hwezuva nezuva, asi inongogumira pakutsvaira pasi, maruva, mapindu, michina yemidziyo, sheaths, etc. Pakutanga, vashandi pakuvaka nzvimbo kunyange Kushandiswa mvura yekuendesa.Kubva pane izvi zvikamu, izvo zvinogona kusangana nevanhu kwenguva yakareba zvinofanirwa kutongerwa sezvisina chepfu kana kuti zvisina basa, asi izvi zvinongogumira kune yekutanga mbishi zvinhu.
Pfungwa yekuchengetedzwa kwezvakatipoteredza yakakura, ingobaya paBaidu, pano kuti utaure nezve pfungwa yekuchengetedzwa kwezvakatipoteredza kwePVC epurasitiki hoses, zvinoreva kuti zvinhu zvakanaya mushure mekuparara kwePVC hoses hazvizokonzerese kukuvadza kumuviri wemunhu.PVC inonzi polyethylene, inova resin powder.Izvo zvinogadzira zvinhu zvinokuvadza mupombi zvinobva kune imwe mbishi inoumba hose, butyl ester, chlorinated parafini, (kana octyl ester, p-benzene, TOTM).Mapaipi akajairika anowanzo kugadzirwa nePVC, butyl ester, chlorine Inoumbwa neparafini wax uye zvimwe zvinobatsira.Butyl ester neparafini hazviwanzo konzera benzene kana tembiricha yadzikira pane 45 degrees celsius, saka haina njodzi uye isina chepfu.
Kudzivirirwa kwezvakatipoteredza kunoreva kuti maPVC hoses akapfuura kuongororwa kwenzvimbo dzine chiremera pasina phthalate precipitation inogona kushandiswa papombi dzemvura yekunwa uye inoonekwa seyakanaka nharaunda.Ichi chinodiwa chakanyanya kuomarara, uye chete zvakatipoteredza zvine hushamwari zvigadzirwa zvinoshandiswa.
Nokudaro, pakusarudza hose, edza kushandisa zvisiri zvehupfu kana zvakatipoteredza zvekushandisa pamba.Mutengo wacho hauna kugadzikana panguva yekubhadhara, uye mukugadzirisa kwekushandisa chigadzirwa, kune mufaro unoperekedzwa, uye kushandiswa kwechubhu hakuna kunetseka.
