Dhakhaatiirta suufka ah ee PBT / xayawaanka

Dhakhaatiirta PBT / PET ee Girt ee Cagaha

Sharraxaadda Gaaban:

Qalabka balaastigga ah ee pbt / PET waxay leedahay astaamaha kululaynta kuleylka wanaagsan, nuugista qoyaanka oo yar, iska caabbinta kiimikada wanaagsan, iska caabbinta cimilada wanaagsan, xoogga korantada ee wanaagsan, xoogga korantada wanaagsan, xoogga xasaasiga ah. Waana fududahay in lagu sameeyo fiber galaas lagu xoojiyo ama dib-u-dhigga dib-u-dhigga, oo loo yaqaan 'ultrasonically' oo si fudud loo shaqeyn karo oo si fudud looga baaraandegi karo. Waxaana si weyn loogu isticmaalaa beeraha korantada iyo elektiroonigga, farsamada iyo kiimikada, baabuurta, iwm.

Calaamadaha wax soo saarka

PBT / PET waa polymoplaster polyterlring injineer injineer heersi ah oo loo isticmaalo insula sifeeyaha ee warshadaha korantada iyo elektiroonigga ah. Waa polymer polymplast (semi-) poly polymer, iyo nooc polyester ah. Waxaa jira mid u adkaysta solvents, hoos u dhaca wax aad u yar inta lagu jiro qaabeynta, farsamo ahaan waa mid xoog badan, illaa iyo 200 ° C oo lagu daaweyn karo muraayadaha-fiber-galaas ah oo lagu daadan karo dib-u-soo-nooleynta. Waxaa soo saaray warshadaha kiimikada ee Ingiriiska (ICE).

Pbbt wuxuu si dhaw ula xiriiraa polurests-ka kale ee heerkulka ah. Marka la barbar dhigo xayawaanka (polyetylene), pbt waxay waxyar ka haysaa xoog yar iyo xoog, xoogaa iska caabin saamayn yar oo sifiican u caabbinta, iyo heerkulka ugu yar ee galaaska yar. PBT iyo xayawaanku waxay u nugul yihiin biyaha kulul ee ka sarreeya 60 ° C (140 ° F). PBT iyo PET waxay u baahan yihiin ilaalin UV haddii loo isticmaalo bannaanka haddii ay bannaanka u isticmaalaan, iyo inta badan darajooyinka badan ee polests-kaan waa kuwo ololi kara, in kasta oo lagu daro waxyaabaha lagu daro labadaba ee loo yaqaan 'UV'.
