PET ndi chidule cha Chingerezi cha Polyethylene terephthalate. Amatanthauza mapulasitiki a polyethylene terephthalate, makamaka kuphatikiza polyethylene terephthalate PET ndi polybutylene terephthalate PBT. Polyethylene terephthalate imadziwikanso kuti polyester resin. Kapangidwe ka pulasitiki ya PET Kapangidwe ka molekyulu

Kodi kusiyana kwa kusindikiza kwa offset ndi kusindikiza kwa digito ndi kotani? Kusindikiza kwa offset kumapangidwa pa chosindikizira pogwiritsa ntchito mbale zosindikizira ndi inki yonyowa. Mtundu uwu wa kusindikiza umatenga nthawi yayitali kuti upangidwe chifukwa pamakhala nthawi yokwanira yokonzekera ndipo chinthu chomaliza chiyenera kuumitsidwa chisanathe. Nthawi yomweyo, o

CPET ndi chinthu choteteza chilengedwe cha polyethylene terephthalate, chomwe chilibe fungo, kukoma, mtundu, kuwonongeka, komanso chosakhala ndi poizoni. Zinthu za CPET zimadziwika kuti ndi zinthu zabwino kwambiri zosungira chakudya padziko lonse lapansi masiku ano. Zinthu za CPET zimadutsa munjira zina zapadera zopangira - Blister pr

Kodi zinthu za pulasitiki za PVC kwenikweni ndi chiyani? PVC, dzina lake lonse ndi Polyvinylchloride, gawo lalikulu ndi polyvinyl chloride, ndipo zinthu zina zimawonjezedwa kuti ziwonjezere kukana kutentha, kulimba, kusinthasintha, ndi zina zotero. Zigawo zitatu za pepala la PVC Gawo lapamwamba la PVC ndi lacquer, gawo lalikulu pakati

Monga gawo lofunika kwambiri la zinthu zosinthasintha za PVC, pulasitiki imakhudza kwambiri magwiridwe antchito a zinthu zosinthasintha za PVC. Ngati zinthu zofewa za PVC (makatani a zitseko zosungiramo zozizira za PVC) zikufunika kugwiritsidwa ntchito kutentha kochepa, mapulasitiki omwe ali ndi kukana kutentha bwino ayenera kusankhidwa.

Bolodi la thovu la PVC ndi pulasitiki yatsopano yopepuka, ndipo PVC ndiye chinthu chachikulu chopangira. Bolodi la thovu la PVC limapangidwa ndi njira zapadera zopangira thovu, monga thovu lopanda madzi kapena celuka. Bolodi la thovu la PVC ndi lolimba, losagwira chinyezi (lodzizimitsa lokha), losasinthasintha, lopanda poizoni, komanso loletsa kukalamba. Pakadali pano, lili ndi e

DOP ndi DOTP ndi mapulasitiki omwe amagwiritsidwa ntchito popanga PVC kukhala yofewa, yosinthasintha komanso yosavuta kuikonza. Kusiyana kwakukulu ndi kapangidwe ka mamolekyu awo: DOP, yomwe nthawi zambiri imatanthauza DEHP, ndi orthophthalate, pomwe DOTP, yomwe imatchedwanso DEHT, ndi terephthalate ndipo nthawi zambiri imasankhidwa ngati njira ina yopanda orthophthalate.

Mitundu yambiri ya zipangizo zapulasitiki imapezeka mumakampani opanga ma paketi. Mukafuna kulongedza zinthu zanu, posachedwa mutha kupeza zipangizo ziwiri zapulasitiki zomwe zimagwiritsidwa ntchito kwambiri: zipangizo zapulasitiki za PET ndi PVC. Ku Huisuqinye Plastics Group, makasitomala nthawi zambiri amatifunsa kuti ndi zipangizo ziti zapulasitiki zomwe zatsimikizika kuti ndi zabwino kwambiri.
