PBT yog lub npe luv ntawm Polybutylene terephthalate. Nws yog cais nyob rau hauv polyester series. Nws yog tsim los ntawm 1.4-Butylene glycol thiab terephthalic acid (TPA) lossis terephthalate (DMT). Nws yog ib qho milky translucent rau opaque, crystalline thermoplastic polyester resin ua los ntawm kev sib xyaw ua ke. Ua ke nrog PET, nws yog hu ua thermoplastic polyester, lossis saturated polyester.
Cov yam ntxwv ntawm PBT Plastics
1. Qhov yooj ywm ntawm PBT yas zoo heev thiab nws kuj tiv taus kev poob, thiab nws qhov kev tiv taus brittle yog qhov muaj zog heev.
2. PBT tsis yooj yim hlawv li cov yas ib txwm muaj. Tsis tas li ntawd xwb, nws lub zog tua hluav taws thiab cov khoom siv hluav taws xob kuj siab heev hauv cov yas thermoplastic no, yog li tus nqi kim heev ntawm cov yas.
3. PBT qhov kev nqus dej tsis tshua muaj zog. Cov yas ib txwm yooj yim deformed hauv dej nrog qhov kub siab dua. PBT tsis muaj teeb meem no. Nws tuaj yeem siv tau ntev thiab tswj tau qhov kev ua tau zoo heev.
4. Qhov saum npoo ntawm PBT du heev thiab qhov sib txhuam coefficient me me, ua rau nws yooj yim dua rau siv. Nws kuj yog vim nws qhov sib txhuam coefficient me me, yog li nws feem ntau siv rau lub sijhawm uas qhov kev poob sib txhuam loj heev.
5. Yas PBT muaj kev ruaj khov zoo heev tsuav yog nws tsim los, thiab nws tshwj xeeb dua txog qhov tseeb ntawm qhov ntev, yog li nws yog cov khoom siv yas zoo heev. Txawm tias nyob rau hauv cov tshuaj lom neeg mus sij hawm ntev, nws tuaj yeem tswj nws lub xeev qub zoo, tshwj tsis yog qee yam tshuaj xws li cov kua qaub muaj zog thiab cov hauv paus muaj zog.
6. Muaj ntau yam yas uas siv cov khoom siv kho kom zoo, tab sis cov khoom siv PBT tsis zoo. Nws cov yam ntxwv ntws zoo heev, thiab nws cov yam ntxwv ua haujlwm yuav zoo dua tom qab molding. Vim tias nws siv cov thev naus laus zis polymer fusion, nws ua tau raws li qee yam khoom siv alloy uas xav tau polymer.
Cov kev siv tseem ceeb ntawm PBT
1. Vim nws cov khoom siv lub cev thiab tshuaj zoo, PBT feem ntau yog siv los ua cov khoom siv extrusion rau txheej txheej thib ob ntawm cov fibers optical hauv sab nraum zoov fiber cable.
2. Cov ntawv thov hluav taws xob thiab hluav taws xob: cov khoom sib txuas, cov khoom hloov pauv, cov khoom siv hauv tsev lossis cov khoom siv ntxiv (ua kom sov, tiv taus hluav taws, rwb thaiv hluav taws xob, yooj yim molding thiab ua tiav).
3. Cov teb siv rau cov khoom siv hauv tsheb: cov khoom sab hauv xws li cov wiper brackets, cov valve tswj system, thiab lwm yam; cov khoom siv hluav taws xob thiab hluav taws xob xws li cov kav dej sib ntswg ntawm lub tsheb thiab cov khoom siv hluav taws xob cuam tshuam.
4. Cov khoom siv dav dav rau cov tshuab siv: lub hau khoos phis tawj, lub hau teeb mercury, lub hau hlau hluav taws xob, cov khoom siv ci thiab ntau lub iav, cams, khawm, lub plhaub moos hluav taws xob, lub tshuab hluav taws xob thiab lwm yam plhaub kho tshuab.
