PET - Polyethylene terephthalate

PET (mankhwala otchedwa polyethylene terephthalate) ndi poliyesitala yokhala ndi kachulukidwe kakang'ono kwambiri ndipo amapangidwa ndi Ensinger m'mawonekedwe amtundu wamba kuti apange makina.PET imapezeka ngati amorphous kapena semi crystalline thermoplastic.Makhalidwe a mtundu wa amorphous wa PET polima ndiwowonekera kwambiri, koma zinthu zotsika zamakina monga kulimba kwamphamvu, komanso mawonekedwe otsika kwambiri.Komabe, Ensinger samapanga zinthu za PET zomwe nthawi zambiri zimakhala m'mabotolo kapena m'matumba.Zodziwika bwino za semi crystalline terephthalate zomwe Ensinger amapanga ndizolimba, kusasunthika, mphamvu, kutsetsereka kwapadera komanso kuvala kochepa (poyerekeza ndi POM m'malo achinyezi kapena owuma).Izi zakhala zikutchedwa pulasitiki ya PET-P, koma iyi ndi njira yakale yofotokozera za PET masiku ano.

Chifukwa cha mphamvu zake zokwawa bwino, kuyamwa kochepa kwa chinyezi komanso kukhazikika kwapamwamba, zinthu zapulasitiki za PET ndizoyenera kugwiritsa ntchito pomwe magawo ovuta komanso zofunika kwambiri zokhudzana ndi kulondola kwa mawonekedwe ndi mawonekedwe apamwamba zimafunikira.Kutentha kwa PET kumathandizira kukhazikika kwa kutentha komanso kukhazikika kwa mawonekedwe.

ZINTHU ZOFUNIKA KWA ZIFUWE NDI MAFUNSO
Zinthu za PET zimapereka:
● Wamphamvu kwambiri
● Kukhazikika kwakukulu ndi kuuma
● Kuchepa kwambiri kwa chinyezi
● Kukana kukwawa bwino
● Kuthamanga pang'ono ndi zovala zoterera
● Kusamva hydrolysis (mpaka +70 °C)
● Sayenera kulumikizana ndi zofalitsa zomwe zili ndi mowa > 50%.
● Kulimbana bwino ndi ma asidi
● Kumamatira bwino ndi kuwotcherera

ZOPANGIDWA ZINTHU ZA PET
Dzina la malonda la Ensinger la zosintha za PET ndi TECAPET kapena TECADUR PET.Ensinger imapereka zosintha zotsatirazi mu Polyester:
● TECAPET - PET yasinthidwa kuti ikhale ndi makina abwino
● TECAPET TF - PET yosinthidwa ndi PTFE kuti ikhale ndi mavalidwe abwino
● TECADUR PET - kalasi ya PET yosasinthika
Ensinger amapereka PET mu mawonekedwe a:
● Ndodo yapulasitiki ya PET
● mapepala apulasitiki a PET
