PBT muaj kev ua tau siab zog, qaug zog thiab ruaj ntseg; tsawg zog noj rau kev ua PBT; zoo heev tshav kub kev laus ua hauj; zoo tsis kam mus organic kuab tshuaj; yooj yim ua thiab kev ua tiav theem nrab; Txawm hais tias PBT yog ib qho tsis zoo nyob hauv tus nqi piv nrog tus tsiaj ntawv, nws tseem nce zuj zus ntawm tus nqi ntawm 15% -20%. Lub ntsiab tseem ceeb yog tias nws muaj kev qhia zoo heev, PBT muaj lub siab crystallization npaum li cas, tuaj yeem tsim tau sai, thiab nws yooj yim rau kev loj. Ua; PBT muaj qhov dej tsis haum, cov khoom hluav taws xob zoo thiab hloov me ntsis pauv; PBT muaj huab cua tsis haum zoo, tsim rau kev siv sab nraum zoov, thiab muaj tshuaj lom neeg kuj zoo heev; PBT muaj cov khoom siv zoo heev.
PBT tau sai crystallization zog, polyamide kuj muaj ib tus nqi siab crystallization thiab tus txheeb ze lub ntsiab lus, thiab muaj kev ntseeg zoo rau kev sib hloov thiab cov khoom siv zoo heev. Qhov txawv ntawm ob qhov khoom yog tias qhov hygroscopicity ntawm PBT yog tsawg dua li ntawm polyamide, dej nqus ntawm PBT24h yog 0.08%, thiab hais tias cov polyamide 6 yog 1.6%. Cov khoom ntawm cov tshuaj polyamide pauv nrog cov av noo, lub modulus thiab lub zog raug txo, thiab qhov feem zog zoo tuaj. Txawm tias muaj qee zaum, cov khoom ua rau cov hlauv ntshauv polyamide tuaj yeem tshwm tuaj ntxiv. Yog li no, designers ntawm polyamide cov khoom yuav tsum xav txog tus cawv ntawm ib puag ncig yam tseem ceeb ntawm kev ua tau zoo ntawm cov khoom. Hauv kev sib piv, PBT muaj tsawg hygroscopicity, thiab qhov khoom loj thiab cov khoom sib txuas khoom muaj feem xyuam nrog ib puag ncig yam tsis tshua muaj hloov, uas qhia tau tias huab cua zoo tuaj.
