Dab tsi yog PET khoom?

1.Pet feem ntau hu ua polyester resin, tseem hu ua polyethylene terephthalate, uas yog qhov tseem ceeb tshaj plaws hauv cov thermoplastic polyester. Nws yog polycondensate ntawm terephthalic acid thiab ethylene glycol. Thermoplastic polyester los yog saturated polyester.

2.Pet yog mis nyuj dawb los yog lub teeb * muaj crystalline polymer, nws nto yog du thiab ci, uas muaj kev nkag siab zoo, qaug zog ua haujlwm, kev sib txhuam tsis kam thiab zoo seem stability, thiab lwm yam.

3.Pet muaj qhov toughness zoo tshaj plaws ntawm cov thermoplastics, uas yog, nws muaj cov hluav taws xob rwb thaiv tsev zoo thiab tsis tshua muaj kev cuam tshuam los ntawm qhov kub thiab txias, tab sis tsis zoo corona kuj. Nws yog non-toxic, muaj huab cua tsis kam, tshuaj lom neeg tsis kam, zoo stability, thiab dej nqus. Tus nqi qis, tiv taus cov kua qaub tsis muaj zog thiab cov kuab tshuaj organic, tab sis tsis tiv taus cov dej kub immersion thiab alkali.

4. Lub iav hloov pauv kub ntawm cov tsiaj resin yog qhov siab, lub crystallization ceev qeeb, lub voj voog molding yog ntev, lub voj voog molding ntev, molding shrinkage tus nqi yog loj, qhov seem stability kuj tsis zoo, lub crystallization molding yog nkig. , thiab tshav kub tsis kam yog tsawg.
