PBT engineering plastics, (polybutylene terephthalate), muaj kev ua tau zoo heev, tus nqi qis, thiab muaj kev ua haujlwm zoo.Hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov cuab yeej siv tshuab, tsheb thiab cov cuab yeej precision thiab lwm yam, nws tau siv dav.
Cov yam ntxwv ntawm kev hloov kho PBT
(1) Cov khoom siv kho tshuab zoo heev, siab zog thiab qaug zog ua haujlwm, zoo qhov ruaj khov thiab me me nkag.Nyob rau hauv qhov kub thiab txias, kev ua haujlwm hloov tsawg dua.
(2) Ib qho yooj yim nplaim taws retardant, thiab nplaim retardant muaj ib tug zoo affinity, yooj yim rau tsim ntxiv hom thiab cov tshuaj tiv thaiv hom nplaim retardant qib, muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm UL94 V-0 qib.Nws tau siv dav hauv kev lag luam hluav taws xob thiab hluav taws xob.
(3) Thaum tshav kub kub ua hauj, laus kuj, organic hnyav kuj.Kev txhim kho UL ntsuas qhov ntsuas kub yog khaws cia nyob rau hauv thaj tsam ntawm 120 ° C txog 140 ° C, thiab tag nrho lawv muaj qhov zoo sab nraum zoov mus sij hawm ntev.
(4) Kev ua haujlwm zoo.Ib qho yooj yim mus rau theem nrab ua thiab molding ua, nrog kev pab los ntawm cov cuab yeej zoo tib yam tuaj yeem yog extrusion molding lossis txhaj tshuaj molding;Nws muaj qhov ceev ceev crystallization thiab fluidity zoo, thiab pwm kub yog qhov tsawg
Hloov cov kev taw qhia ntawm PBT
1. Kev hloov kho kom zoo
Hauv PBT ntxiv cov iav fiber ntau, iav fiber ntau thiab PBT resin bonding quab yuam yog qhov zoo, hauv PBT resin ntxiv cov iav fiber ntau, tsis tsuas yog tuaj yeem tswj cov PBT resin tshuaj tiv thaiv, kev ua haujlwm thiab lwm yam tseem ceeb, tab sis kuj tuaj yeem muaj qhov zoo ntawm cov iav fiber ntau. Kev nce ntxiv hauv nws cov khoom siv kho tshuab, thiab kov yeej PBT resin notch rhiab heev.
2. Kev hloov kho nplaim taws
PBT yog crystalline aromatic polyester, tsis muaj nplaim retardant, nws cov nplaim retardant yog UL94HB, tsuas yog tom qab ntxiv cov nplaim retardant, tuaj yeem ncav cuag UL94V0.
Feem ntau siv cov nplaim hluav taws kub hnyiab tau muaj bromide, Sb2O3, phosphide thiab chloride halogen nplaim retardants, xws li feem ntau yog kaum bromine biphenyl ether, tau PBT loj, nplaim hluav taws, tab sis vim yog kev tiv thaiv ib puag ncig, European lub teb chaws tau txwv ntev siv, lub ob tog tab tom nrhiav kev hloov, tab sis tsis muaj kev ua tau zoo tau ntau tshaj kaum bromine biphenyl ether hloov.
3. Kev hloov kho ntawm kev sib xyaw alloy
Lub hom phiaj tseem ceeb ntawm PBT sib xyaw nrog lwm cov polymers yog txhawm rau txhim kho qhov cuam tshuam ntawm lub zog, txhim kho kev sib hloov deformation los ntawm molding shrinkage, thiab txhim kho cov cua sov.
Kev sib xyaw yog dav siv los hloov kho nws hauv tsev thiab txawv teb chaws.Lub ntsiab hloov pauv polymers siv rau PBT sib xyaw yog PC, PET, thiab lwm yam. Cov khoom no yog siv rau hauv tsheb, hluav taws xob thiab cov cuab yeej hluav taws xob.Qhov feem ntawm cov iav fiber ntau txawv, thiab nws daim ntawv thov teb kuj txawv.
Kev siv tseem ceeb ntawm cov ntaub ntawv PBT
1. Cov khoom siv hluav taws xob
Tsis muaj fuse breaker, electromagnetic hloov, tsav rov qab transformer, cov khoom siv hauv tsev kov, connector, thiab lwm yam. PBT feem ntau yog ntxiv 30% iav fiber ntau sib xyaw ua cov khoom sib txuas, PBT tau siv dav vim cov khoom siv kho tshuab, hnyav ua haujlwm, tsim ua thiab tus nqi qis.
2. Thaum tshav kub kub dissipation kiv cua
Iav fiber reinforced PBT feem ntau yog siv rau hauv cov cua kub dissipation kiv cua, cov cua kub dissipation kiv cua tau muab tso rau hauv lub tshuab kom ntev ntev los pab cov cua sov dissipation, cov khoom ntawm lub cev ntawm cov yas yuav tsum muaj cua sov, flammability, rwb thaiv tsev thiab txhua yam muaj zog, PBT yog feem ntau nyob rau hauv daim ntawv ntawm 30% fiber ntau thov raws li lub tshav kub dissipation ntxuam sab nraum lub thav duab thiab kiv cua hniav coil ncej.
3. Cov khoom siv hluav taws xob
Iav fiber reinforced PBT kuj yog siv los ua ib qho kev hloov pauv, relay hauv lub kauj ncej, feem ntau PBT ntxiv rau fiber ntau 30% kev txhaj tshuaj.Cov khoom siv lub cev uas xav tau ntawm lub kauj ncej muaj xws li rwb thaiv tsev, kub tsis kam, vuam tsis kam, fluidity thiab lub zog, thiab lwm yam. Cov ntaub ntawv tsim nyog yog GLASS fiber reinforced PBT, GLASS FIBER reinforced PA6, GLASS FIBER reinforced PA66, thiab lwm yam.
4. Automotiventu
A. Cov khoom siv sab nrauv: feem ntau yog lub tsheb bumper (PC / PBT), qhov rooj kov, lub kaum ntse ntse, lub cav cua sov tso lub qhov npog, lub qhov rais tsheb lub plhaub, fender, hlau npog, lub log npog lub tsheb kis iav lub thawv, thiab lwm yam.
B. Sab hauv: feem ntau suav nrog endoscope brace, wiper bracket thiab tswj qhov system valve;
C, automotive hluav taws xob qhov chaw: automotive ignition coil twist tube thiab ntau yam hluav taws xob connectors, thiab lwm yam.
Nyob rau tib lub sijhawm, nws tseem tuaj yeem siv rau lub plhaub phom ntawm lub zog tshiab.
5. Cov cuab yeej siv tshuab
Cov khoom siv PBT kuj tau siv dav hauv daim kab xev kaw lus siv lub tshuab tsav tsheb, lub khoos phis tawj npog, mercury lampshade, hlau npog, ci tshuab qhov chaw thiab ntau lub iav, CAM, khawm, hluav taws xob saib vaj tse, lub koob yees duab qhov chaw (nrog rau cov cua sov, nplaim taws retardant yuav tsum. )
