Masiku ano eni eni magalimoto ochulukirachulukira pakusankha mkati mwagalimoto yamagalimoto awo amasokonezeka momwe angasankhire pakati pa chikopa cha PU ndi PVC, lero tisanthula kuchokera kuzinthu zingapo za PU ndi PVC pamapeto pake kusiyana kwake ndi chiyani.
Chiyambi cha PU Chikopa:
Chikopa cha polyurethane, chomwe chimadziwika kutiPU chikopa,ndichikopa chochita kupanga.Amapangidwa ndi polima ya thermoplastic ndipo amagwiritsidwa ntchito popanga nsapato ndi mipando.PU chikopandi osakaniza osiyanasiyana yokumba mankhwala;chifukwa chake ndi 100% vegan.Ili ndi mawonekedwe ofanana ndi a chikopa chenicheni, koma nthawi zambiri imakhala yopepuka, yosakhazikika, komanso imalimbana ndi kuwala kwa dzuwa.
Chiyambi cha PVC Chikopa:
PVC chikopa, kapena nthawi zina amatchedwa Vinyl, amapangidwa kuchokera ku chikopa cha nsalu, chopangidwa ndi thovu, khungu la khungu ndiyeno pulasitiki yochokera pamwamba.
Zithunzi za PVCndi ufa woyera wokhala ndi mawonekedwe aamorphous, digiri yaing'ono ya nthambi, kachulukidwe kapafupipafupi pafupifupi 1.4, kutentha kwa magalasi 77 ~ 90 ℃, kuwonongeka kumayambira 170 ℃, kusakhazikika kwa kuwala ndi kutentha, pamwamba pa 100 ℃ kapena kukhudzana ndi dzuwa kwa nthawi yaitali. kuwola ndi kutulutsa hydrogen chloride, ndi kuwonongeka kwina kwa auto-catalytic, kuchititsa kusinthika, mawonekedwe akuthupi ndi makina amatsikanso mwachangu, pogwiritsira ntchito kuyenera kuwonjezeredwa Stabilizer iyenera kuwonjezeredwa kuti ipititse patsogolo kukhazikika kwa kutentha ndi kuwala.
PU ChikopaVSChikopa cha PVC:
●Njira Yopangira
✧PVC chikopa: Popanga, ma granules apulasitiki ayenera kusungunuka ndi kutenthedwa kukhala phala, atakulungidwa mofanana pa gawo laling'ono la T / C loluka molingana ndi makulidwe ake, kenako amalowa mu ng'anjo yotulutsa thovu kuti achite thovu, kuti akhale ndi zofewa zomwe zimatha kutengera kupanga zinthu zosiyanasiyana ndi zofunikira zosiyanasiyana, ndipo chithandizo chapamwamba chimachitika nthawi yomweyo pomwe ng'anjo imatulutsidwa.
✧PU chikopa: Popanga zinthu kuposaPVC chikopaNdizovuta pang'ono, chifukwa kuthandizira kwa PU ndi chinsalu cholimba champhamvuPU zinthu, kuwonjezera pamwamba pa chithandizocho chikhoza kuphimbidwa, komanso chothandiziracho chikhoza kukhala pakati, kotero kuti kunja sikungathe kuwona kukhalapo kwa nsalu zapansi.
●Mwakuthupi
✧PU Chikopa: Zowoneka bwino kuposa PVC zikopa, kukana flexural, kusinthasintha kwabwino, kulimba kwamphamvu, kupuma.
✧PVC Chikopa: Kukhazikika kwabwino ndi katundu wa dielectric, wokhazikika komanso wotsutsa kukalamba, wosavuta kuphatikizira komanso wolumikizana.
● Mtengo
Mtengo waPU chikopandi kuposa kuwirikiza kawiriPVC chikopa, ndi mtengo wa chikopa chapadera cha PU, mongamicrofiber chikopa, ndi nthawi 2-3 kuposa chikopa cha PVC.Nthawi zambiri, pepala lachikopa lofunikira pa chikopa cha PU litha kugwiritsidwa ntchito nthawi 4-5, ndipo chodzigudubuza chimakhala ndi moyo wautali, chifukwa chake mtengo wake.PU chikopandi apamwamba kuposa aPVC chikopa.
●Kuchuluka kwa ntchito
Chikopa cha ✧PVC: Chikopa cha PVC chimagwiritsidwa ntchito kwambiri popanga zingwe kapena zida zosalemetsa, monga chivundikiro chapampando wamagalimoto ndi mphasa zamapazi agalimoto.
✧PU Chikopa: Chikopa cha PU chitha kuyikidwa pagawo lolemera lazokongoletsa zamagalimoto, monga chiwongolero chagalimoto, madenga ndi chivundikiro chapampando wamagalimoto.
● Kusagwira kutentha
✧PU chikopa: The pazipita kutentha kukana akhoza kufika 90 ℃.
✧PVC chikopa: The pazipita kutentha kukana 65 ℃.
●Kufewa
Kufewa kwa PU chikopa ndi chofewa kukhudza poyerekeza ndi chikopa cha PVC, chikopa cha PVC chitha kuwonjezera pulasitiki kuti chikhale chofewa, plasticizer ndi chowonjezera kuti PVC ikhale yofewa, koma mfundo za chakudya zimakhala ndi zofunikira zokhwima za plasticizer, kotero PVC yofewa, plasticizer ndi kwenikweni kutali ndi kukwaniritsa zofunikira zachilengedwe.
●Zigawo
✧PU Chikopa: Polyurethane, ndi dzina lophatikizana lazinthu zingapo za polyurethane (polyurethane), chinthu chomwe chikutuluka polima, chomwe chimadziwika kuti "pulasitiki yayikulu yachisanu".Zida zazikulu zopangira polyurethane synthesis ndi organic polyisocyanates ndi end-hydroxy compounds.
✧PVC chikopa: Polyvinyl kolorayidi, kapena polyvinyl kolorayidi, ndi polima wopangidwa ndi polymerization wa vinilu kolorayidi monoma (VCM) pamaso pa intiators monga peroxides ndi mankhwala azo, kapena pamaso pa kuwala kapena kutentha mu free radical polymerization. reaction limagwirira.Vinyl chloride homopolymers ndi vinyl chloride copolymers onse pamodzi amatchedwa vinyl chloride resins (PVC resins).
●Kukoma
✧PU chikopa: Mukawotcha PU ndi moto, fungo lake ndi lopepuka.
✧PVC Chikopa: Mukawotcha PVC ndi moto, imasanduka yakuda ndikutsagana ndi fungo lamphamvu kwambiri.
Bensen paPU chikopandiPVC chikopa, yokhala ndi mphamvu zambiri komanso yokhazikika kwambiri, komanso yosayaka, imatha kukana dzimbiri zomwe zimadza chifukwa cha kusintha kwa nyengo, zomwe zimagwiritsidwa ntchito kwambiri pokongoletsa mkati mwa magalimoto.Mutha kusankha zinthu zomwe mumakonda komanso zoyenera pagalimoto yanu.
Ngati mukufuna, chonde omasuka kulankhula nafe.
