Mushure mekunge chinhu chinosimbisa muviri chachinjwa kubva pamunyu wemutobvu kuenda pacalcium zinc stabilizer, zviri nyore kuona kuti ruvara rwechigadzirwa runowanzova rwegirini, uye zvakaoma kuchinja ruvara kubva pagirini kuenda patsvuku.
Mushure mekunge chinhu chinosimbisa ganda chezvigadzirwa zvePVC chachinjwa kubva pakuva munyu we lead kuita calcium zinc stabilizer, matambudziko eruvara inyaya yakajairika uye yakasiyana-siyana iyo yakaoma kugadzirisa. Zviratidzo zvayo zvinosanganisira zvinotevera:
1. Kutsiviwa kwezvinodzivirira kunotungamira kuchinjwa kweruvara rwechigadzirwa. Mushure mekunge chinodzivirira chachinjwa kubva pakuva munyu wemutobvu kuenda kucalcium zinc stabilizer, zviri nyore kuona kuti ruvara rwechigadzirwa runowanzova rwegirini, uye zvakaoma kuwana shanduko yeruvara kubva pagirini kuenda kutsvuku.
2. Ruvara rwechigadzirwa mukati nekunze haruna kuenzana mushure mekushandisa calcium zinc stabilizer. Kazhinji, ruvara rwekunze runenge rwakanaka, nepo ruvara rwemukati runowanzova rwebhuruu-girini uye yero. Izvi zvinogona kuitika zviri nyore mumaprofiles nemapaipi.
3. Kuchinja kwemavara ezvigadzirwa panguva yekugadzirisa mushure mekushandisa calcium zinc stabilizers. Mukushandisa lead salt stabilizers kugadzirisa zvigadzirwa, panogona kunge paine kutsauka kwemavara pakati pemichina yakasiyana uye panguva dzakasiyana mukati memuchina mumwe chete, asi huwandu hwekuchinja hushoma. Mushure mekushandisa calcium zinc stabilizers, kuchinja uku kunogona kukura, uye kukanganisa kwekuchinja kudiki kwezvinhu zvakagadzirwa uye maitiro pahunhu kunogonawo kuoneka zvakanyanya. Munyori akasangana nemamiriro ezvinhu apo vatengi vanoshandisa calcium zinc stabilizers kugadzira mapaipi uye fittings, uye kuchinja kwekumanikidzwa hakungokanganisi ruvara rwechigadzirwa chete, asiwo kunokanganisa mashandiro acho. Kuchinja uku kunonyanya kunzwisisika kupfuura pakushandisa lead salt stabilizers.
4. Nyaya yeruvara rwezvigadzirwa panguva yekuchengetera, kutakurwa, uye kushandiswa mushure mekushandisa zvinosimbisa zvakatipoteredza zvine calcium zinc. Zvigadzirwa zvePVC zvakasimba zvinoshandisa zvisimbisa zvakatipoteredza zvine lead salt stabilizers hazvina shanduko huru yeruvara panguva yekuchengetera, kutakurwa, uye kushandiswa. Mushure mekushandurwa kuita zvinosimbisa zvakatipoteredza zvine calcium ne zinc, panogona kunge paine katsika kekuti chigadzirwa chiite yero nebhuruu mushure mekumira. Zvimwe zvinosimbisa zvinogona kukonzera kuti chigadzirwa chiite dzvuku kana chikashandiswa muzvigadzirwa zvine iron ion yakawanda mu calcium powder yakawedzerwa.
