Pankhani yodzimatira, aliyense ayenera kuganizira za PET ndi PVC, koma mumadziwa bwanji za zilembo zopangidwa ndi PET ndi PVC? Lero, ndiroleni ndikuwonetseni:
Kusiyana 1
The raw material mawonekedwe ndi osiyana:
PVC, ndiko kuti, polyvinyl chloride, mtundu woyambirira ndi wonyezimira pang'ono komanso wonyezimira.
PET, ndiye kuti, polyethylene terephthalate, imamveka bwino kwambiri.
Mphamvu ya zopangira ndizosiyana:
PVC, ndiko kuti, polyvinyl chloride, imamveka bwino kuposa polyethylene ndi polystyrene, koma yoyipa kuposa polyethylene. Imagawidwa kukhala yofewa komanso yolimba ya polyvinyl chloride malinga ndi kuchuluka kwa zosintha zomwe zimagwiritsidwa ntchito. Chofewacho ndi chofewa komanso cholimba, ndipo chimamveka chomata. Mphamvu ya chinthu cholimba ndi yapamwamba kuposa ya polyethylene yotsika kwambiri, koma yotsika kuposa ya polypropylene, ndipo kuyera kudzachitika popindika.
PET, ndiko kuti, polyethylene terephthalate, ili ndi mphamvu zopondereza bwino komanso ductility kuposa polyethylene ndi polyvinyl chloride, ndipo sizovuta kusweka.
Magwiridwe azinthu zopangira ndizosiyana:
PVC, ndiko kuti, zinthu wamba wa polyvinyl kolorayidi: matabwa, mapaipi, nsapato nsapato, zidole, mazenera ndi zitseko, zikopa chingwe, stationery, etc.
PET, ndiko kuti, kugwiritsa ntchito wamba kwa polyethylene terephthalate: nthawi zambiri imawoneka m'malemba azinthu omwe amafunikira madzi ambiri, osamva alkali, osamva mankhwala, osagwira kutentha ndi zinthu zina, zomwe zimagwiritsidwa ntchito pazida za bafa, zosamalira khungu, zosiyanasiyana zapakhomo. zida, makina opanga, etc.

1. PVC sichitha kugwiritsidwanso ntchito, koma PET ndi yobwezerezedwanso;
2. Ngati mugwiritsa ntchito mabotolo a PET ndi zilembo za PVC, muyenera kuchotsa zilembo za PVC pokonzanso mabotolowo; pomwe zolemba za PET siziyenera kuchotsedwa;
3. PET ili ndi zida zabwino kwambiri za dielectric, zokhala ndi anti-fouling, anti-scratch, kukana kutentha kwakukulu ndi zina;
4. PVC ndi PET ali ndi katundu wofanana. Ili ndi kusinthasintha kwabwinoko komanso kumva kofewa kuposa PET, koma PVC ili ndi kuwonongeka kocheperako ndipo imakhala ndi zotsatira zoyipa pakuteteza chilengedwe.
5. PET nthawi zambiri imakhala ndi PET yoyera kapena PET yowonekera, ndipo imatha kupangidwanso kukhala golide kapena siliva pamwamba, yomwe imawoneka yokongola kwambiri.
6. Zolemba za PET zimakhala ndi makina abwino, kukana kwamphamvu, kukana mafuta komanso kukana mafuta. Kukana kutentha kwambiri komanso kutsika kumakhalanso kolimba kuposa mapulasitiki ambiri, kotero zomata zakukhitchini zomwe timaziwona nthawi zambiri zimapangidwa ndi zojambulazo za PET + aluminiyamu.
7. Zinthu za PET zimakhala zowonekera bwino komanso zofewa zabwino pansi pa 25u. Amagwiritsidwa ntchito kwambiri popangira njinga zamoto ndi njinga zamoto komanso zolemba zina zamagetsi. White PET imagwiritsidwa ntchito makamaka pama batire a foni yam'manja, ndi zina zambiri.
8. Kusiyanitsa kwakukulu ndi PVC ndikuti ili ndi kukhazikika kosasunthika kwa kutentha ndipo imakalamba mosavuta ndi kuwala, kutentha ndi mpweya. Kuphatikiza apo, zowonjezera zambiri zapoizoni nthawi zambiri zimawonjezeredwa panthawi yopanga PVC.

PET: yolimba, yolimba, yolimba kwambiri, yowala pamwamba, yogwirizana ndi chilengedwe, ma sheet owonekera komanso amitundu yambiri. Choyipa ndichakuti kulumikiza kutentha kwapafupipafupi kwa PET ndikovuta kwambiri ndipo mtengo wake ndi wokwera mtengo kwambiri kuposa PVC. Izi nthawi zambiri zimasinthidwa ndi PVC ndi ogwiritsa ntchito omwe amafunikira zinthu zabwino komanso kuteteza chilengedwe. Zida za PET nthawi zambiri zimagwiritsidwa ntchito popanga mabotolo apulasitiki, mabokosi oyika zakudya, ndi zina.
PVC: Chithuza chomwe chimagwiritsidwa ntchito kwambiri chomwe ndi chofewa, cholimba, komanso pulasitiki. Ikhoza kupangidwa mowonekera komanso mumitundu yosiyanasiyana. Transparent PVC nthawi zambiri imagwiritsidwa ntchito kuyika zida zamagetsi, zodzoladzola, zoseweretsa, mphatso, ndi zinthu zina.
