PBT Engineering Treastics, (Polybutylene Terephthalate), muaj kev ua tau zoo, tus nqi qis, thiab muaj cov khoom siv zoo moulding. Hauv cov khoom siv hluav taws xob, khoom siv hluav taws xob, khoom siv kho txhua yam, kho tsheb thiab cov chaw ua lag luam thiab lwm daim teb, nws tau siv dav.
Cov yam ntxwv ntawm Hloov PBT
(1) Cov khoom siv zoo heev, muaj zog siab thiab nkees ua kom tsis kam, muaj kev ruaj khov me me thiab nkag mus me me. Nyob rau hauv cov kev mob siab, kev ua tau zoo hloov tsawg dua.
(2) Yooj yim nplaim taws retardant, thiab nplaim retardant muaj ib tug zoo affinity, yooj yim los tsim cov nplaim hluav taws xob, tuaj yeem ua tau raws li qhov yuav tsum tau ua ul94 v-0 qib. Nws tau siv dav hauv electronics thiab kev lag luam hluav taws xob.
(3) Thaum tshav kub kub tiv taus, cov laus tiv taus, organic kuab tshuaj tiv thaiv. Lub txhim kho hloov kho qhov ntsuas kub tau khaws cia hauv thaj tsam ntawm 120 ° C rau 140 ° C, thiab txhua tus ntawm lawv muaj kev laus nyob sab nraud ntev.
(4) kev ua tiav zoo. Yooj yim rau kev ua tau yooj yim thiab kev yoog cov khoom siv, nrog kev pab ntawm cov cuab yeej zoo tib yam tuaj yeem ua rau muaj kev sib dhos lossis kev txhaj tshuaj moulding; Nws tau ceev ceev crystallization tus nqi thiab cov kua zoo, thiab cov pwm kub yog qhov tsawg
Hloov Kho Kev Taw Qhia ntawm PBT
1. Txhim Kho Kev Hloov Kho
Nyob rau hauv lub pbt ntxiv cov fiber ntau, iav fiber thiab PBT resin ntxiv, tsis muaj peev xwm tswj cov khoom cob muaj fiber ntau, tsis muaj peev xwm tswj tau cov txiaj ntsig PBT ntxiv, tsis muaj thiab lwm yam thawj qhov zoo, tab sis kuj tuaj yeem muaj a Qhov loj loj nce nyob rau hauv nws cov khoom siv tshuab, thiab kov yeej lub PBT resin nthuav dav.
2. Hluav taws retardant hloov kho
PBT yog lub crystalline polyester, tsis muaj nplaim retardant yog ul94hb, tsuas yog tom qab ntxiv ntawm nplaim taws retardant, tuaj yeem ncav cuag ul94v0.
Cov nplaim taws uas nquag siv bromide, sb2o3, nplaim taws loj, tab sis yog cov neeg tiv thaiv ib puag ncig, cov teb chaws Europe muaj cov bans ntev, tus Cov tog neeg tab tom nrhiav kev hloov, tab sis tsis muaj qhov txiaj ntsig zoo tau ua ntau dua li kaum bromine biphenyl hloov.
3. Kev Hloov Kho ntawm Blending Alloy
Lub hom phiaj tseem ceeb ntawm PBT uas muaj zog nrog lwm cov noob polymers yog txhawm rau txhim kho qhov tsis tshua muaj zog cuam tshuam, txhim kho kev sib tsoo ntawm kev ua kom pom kev shrinkage.
Kev sib tsoo tau siv dav siv los hloov nws hauv tsev thiab txawv teb chaws. Lub ntsiab hloov polymers siv rau PBT kev ua txhaum yog PC, Tsiaj, thiab lwm yam ntawm cov khoom lag luam yog siv hauv cov cuab yeej siv hluav taws xob. Qhov ntsuas ntawm cov iav fiber ntau txawv, thiab nws daim ntawv thov teb kuj txawv.
Cov ntawv thov tseem ceeb ntawm PBT cov ntaub ntawv
1. Cov Khoom Siv Hluav Taws Xob
Tsis muaj ib lub fuse cov khoom siv, tsav rov qab los ua cov khoom sib txuas hauv tsev, txuas ntxiv vim yog cov khoom siv tshuab, kev ua cov khoom lag luam thiab tus nqi qis.
2. Cua sov dissipation ntxuam
Cov iav fiber ntau ntxiv txhawb nqa PBT feem ntau yog muab tso rau hauv cov yas ua kom sov, cov khoom cua sov, rwb thaiv tsev thiab tshuab zog, PBT yog Feem ntau nyob rau hauv daim ntawv ntawm 30% siv fiber ntau thov raws li cov cua sov dissipation ntxuam sab nraum lub ncej thiab kiv cua hniav chev.
3. Cov Hluav Taws Xob Hluav Taws Xob
Cov iav Fiber ntxiv txhawb PBT kuj tseem siv los ua tus hloov pauv, relay sab hauv lub coil ncej, feem ntau pbt ntxiv fiber 30% txhaj tshuaj. Cov khoom siv lub cev yuav tsum muaj xws li rwb thaiv tsev, kub ua kom muaj zog ntxiv, thiab lwm yam khoom siv hluav taws xob, thiab lwm yam.
4. AUtomotiveqhov chaw
A. Qhov chaw sab nraud: feem ntau tsheb bumper (PC / PBT), lub qhov rooj kov, fender, hlau npog tsheb kis tsheb kis tau, thiab lwm yam.
B. Cov ntu sab hauv: Feem ntau suav nrog endoscope brace, wiper bracket thiab tswj lub zog system;
C, Automotive Qhov Chaw: Automotive Iignition Coil Twist Tube thiab ntau yam hluav taws xob txuas, thiab lwm yam.
Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem siv rau lub plhaub them nqi ntawm cov tsheb hluav taws xob hluav taws xob tshiab.
5. Cov Khoom Siv Txhua Yam
PTBT cov khoom tseem muaj siv dav hauv cov kab xev video kaw lus, lub pob tshuaj ci, tshuab hluav taws xob, tshuab hluav taws xob (nrog kub, nplaim taws retardant )
