Polybutylene terephthalate (PBT), polyester ua los ntawm polycondensation ntawm terephthalic acid thiab 1,4-butanediol, yog ib qho tseem ceeb thermoplastic polyester thiab ib qho ntawm tsib loj engineering yas.
Properties ntawm PBT
- Mechanical zog: Lub zog muaj zog, qaug zog ua haujlwm, qhov ruaj khov, thiab qis qis (txawm tias nyob rau hauv qhov kub thiab txias).
- Thaum tshav kub kub aging kuj: Txhim kho UL qhov ntsuas kub ntawm 120-140 ℃ (zoo rau sab nraum zoov kev laus ua haujlwm ntev).
- Solvent resistance: Tsis muaj kev ntxhov siab tawg.
- Dej stability: PBT yog nquag decomposition thaum sib cuag nrog dej (siv ceev faj nyob rau hauv high-temperature, high humidity ib puag ncig).
Feem ntau PBT resin tau ua tiav rau hauv kev sib xyaw, hloov kho nrog ntau yam khoom ntxiv, thiab sib xyaw nrog lwm cov resins kom tau txais cov cua sov zoo, nplaim hluav taws xob, hluav taws xob rwb thaiv tsev, thiab lwm yam kev ua tau zoo, nrog rau kev ua haujlwm zoo. Nws yog dav siv hauv cov khoom siv hluav taws xob, tsheb, tsheb tsim, kev sib txuas lus, khoom siv hauv tsev, tsheb thauj mus los, thiab lwm yam lag luam.
Cov ntawv thov PBT
- Electronics thiab Cov Khoom Siv Hluav Taws Xob: Tsis muaj fuse disconnectors, electromagnetic switches, transformers, appliance handles, connectors, and housings.
- Automotive: Qhov rooj kov, bumpers, distributor disc npog, fenders, log npog, thiab lwm yam.
- Cov khoom lag luam: Ntxuam, keyboards, nuv ntses reels, qhov chaw, lampshades, thiab lwm yam.
PBT yog ib qho yooj yim rau txheej txheem thiab tuaj yeem txhaj tshuaj molded lossis extruded. PBT cov khoom lag luam muaj cov kev cai tshwj xeeb rau kev ua kom tiav thiab khawb tsis kam. Muaj ntau txoj hauv kev los txhim kho qhov smoothness ntawm PBT txhaj tshuaj molded cov khoom, xws li ntxiv cov pa qis molecular hnyav silicone / siloxane additives zoo li silicone roj, silicone kua, los yogUltra-siab molecular hnyav silicone masterbatch (siloxane masterbatch).
Txawm li cas los xij, Hauv kev tsim khoom thiab kev ua tiav tiag tiag, ntau lub tuam txhab tau pom tias siv cov khoom siv qis molecular hnyav silicone tuaj yeem ua rau PBT cov khoom tsis xws luag, yog li cuam tshuam rau qhov zoo. Cov hauv qab no yog cov teeb meem tshwm sim uas cuam tshuam nrog kev siv qis molecular hnyav silicone additives:
- PBT cov khoomTsis txaus Nto Smoothness:
Tsawg molecular hnyav silicone additives muaj cov resin feem ntau thiab cov ntsiab lus silicone tsawg. Txawm hais tias cov additives no pheej yig, lawv feem ntau ua tsis tau raws li qhov yuav tsum tau ua rau saum npoo thiab feem ntau yuav tsum tau ntxiv rau hauv cov proportions siab heev kom ua tau zoo. Nws raug pom zoo kom xaivultra-siab molecular hnyav silicone additiveskom ua tiav qhov zoo tshaj plaws nrog qhov sib ntxiv me me.
- PBT cov khoomCov nplaum nplaum thiab nag lossis daus:
Ntxiv ntau qhov hnyav molecular hnyav silicone additives tuaj yeem ua rau lawv tsiv mus rau qhov chaw dhau sijhawm, ua rau nag lossis daus. Nws raug nquahu kom sivultra-siab molecular hnyav silicone additives. Piv nrog rau cov pa qis molecular hnyav silicone / siloxane additives xws li roj silicone, silicone kua, los yog lwm yam kev pab cuam,ultra-siab molecular hnyav silicone masterbatchmuab cov txiaj ntsig zoo dua, Cov tuam txhab zoo li SILIKE kevSILIKE LYSI series Ultra-High Molecular Nyhav Silicone Masterbatch.
Txhim kho Nto Smoothness hauv PBT Cov Khoom Txhaum Cai nrogSILIKELYSI SeriesUltra-High Molecular Nyhav Silicone Masterbatch
SILIKE LYSI series ultra-siab molecular hnyav silicone masterbatch (siloxane masterbatch)yog pelletized formulation nrogultra-siab molecular hnyav siloxane polymerdispersed nyob rau hauv ntau yam resin carriers. Nws yog dav siv los ua cov khoom siv tau zoo hauv cov khoom siv sib xws los txhim kho cov khoom ua haujlwm thiab hloov kho qhov zoo.
TSEEM CEEB-408ultra-high molecular hnyav silicone masterbatch yog pelletized formulation nrog 30% ultra-siab molecular hnyav siloxane polymer dispersed nyob rau hauv polyester (PET). Nws yog dav siv los ua cov khoom siv tau zoo rau PET thiab PBT-tshaj cov tshuab ua haujlwm txhawm rau txhim kho cov khoom ua haujlwm thiab qhov zoo.
NtxivSILIKE ultra-siab molecular hnyav silicone masterbatch (siloxane masterbatch) LYSI-408rau PBT ntawm 0.2 ~ 1% tuaj yeem muab cov txiaj ntsig hauv qab no:
- Txhim kho kev ua haujlwm thiab ntws ntawm cov resin yuav tsum..
- Zoo pwm filling.
- Tsawg extruder torque thiab lubricants sab hauv.
- Cov pwm tso tawm yooj yim dua thiab nrawm dua.
Nyob rau theem siab ntxiv (2 ~ 5%)ntawmSILIKE ultra-siab molecular hnyav silicone masterbatch, cov txiaj ntsig hauv qab no tuaj yeem ua tiav:
- Txhim kho cov khoom nto.
- Txhim kho lubricity, plam, thiab qis coefficient ntawm kev sib txhuam.
- Zoo hnav thiab khawb kuj.
Qhov tseeb, muaj lus nug ntxiv txog PBT txhaj tshuaj molding khoom uas tsis tau teev nyob rau ntawm no.
