Dhalo Cabbitaan Kaarboon-kaarboon ah Heerka PET Resin
Hordhac Product
Cabbitaannada darajada poliester-ka ee kaarboon-kaarboon-ku-salaysan waa kobolymer-ka-beerista polyetylen-ku-saleysan TPA.Waa polymer miisaan sare leh oo loogu talagalay isticmaalka guud ee weelasha wax soo saarka.Waxa loo isticmaali karaa samaynta dhalooyinka wax lagu shubo ee cabitaanka fudud ee kaarboon sida koola iyo 3-gallon, 5-gallon dhalooyin waaweyn.
Astaanta badeecada waxaa ku jira waxyaabo bir ah oo hooseeya, maadada acetaldehyde oo yar, midab wanaagsan.Viscosity deggan oo u fiican habaynta.Iyada oo la karinayo habka gaarka ah iyo tignoolajiyada wax soo saarka sare leh, xoojinta xakamaynta habka iyo maaraynta tayada, badeecada leh hantida go'doominta ee aad u fiican waxay wax ku ool u tahay ilaalinta kaarboon-dioxide ka soo daadinta, wanaagsan ee iska caabinta cadaadiska, ka-hortagga heerkulka hooseeya, baaxadda ballaaran ee processing, heer sare ah daah-furnaanta, heerka sare ee heerka badeecada oo si wax ku ool ah uga hortagi kara dhalooyinka inay jabiyaan cabitaannada kaarboonaysan ee ku jira xilliga kaydinta iyo cadaadiska.

Shuruudaha Habraaca Caadiga ah
Qalajintu waa lagama maarmaan ka hor habaynta dhalaalidda si looga hortago xabagta biyaha.Xaaladaha qalajinta caadiga ah waa heerkulka hawada 165-185 ° C , 4-6 saacadood wakhtiga joogitaanka, heerkulka barta- sayaxa ka hooseeya -40 * C .
Heerkulka foostada caadiga ah waa 280-298 ° C.
