Balaastigga injineernimada PBT, (polybutylene terephthalate), waxay leedahay waxqabad dhammaystiran oo heersare ah, qiimo jaban, waxayna leedahay habayn wanaagsan.Qalabka elektiroonigga ah, qalabka korantada, qalabka farsamada, baabuurta iyo qalabka saxda ah iyo goobaha kale, ayaa si weyn loo isticmaalay.
Astaamaha PBT ee wax laga beddelay
(1) Sifooyin farsamo oo aad u wanaagsan, xoog sare iyo iska caabin daal, xasillooni cabbir wanaagsan iyo gurguurta yaryar.Xaaladaha heerkulka sare, waxqabadku wuu yareeyaa.
(2) Dab-dejinta fudud ee ololka, iyo ololka retardant waxa uu leeyahay xidhiidh wanaagsan, fududahay in la horumariyo nooca lagu daray iyo nooca falcelinta darajada ololka, waxa ay buuxin kartaa shuruudaha darajada UL94 V-0.Waxaa si weyn loogu isticmaalay qalabka elektiroonigga ah iyo warshadaha korontada.
(3) Iska caabbinta kulaylka, caabbinta gabowga, caabbinta dareeraha organic.Tilmaanta heerkulka UL ee la xoojiyay waxaa lagu hayaa inta u dhaxaysa 120 ° C ilaa 140 ° C, dhammaantoodna waxay leeyihiin gabow wanaagsan oo dibadda ah.
(4) Waxqabadka habaynta wanaagsan.Si fudud u habaynta heerka labaad iyo farsamaynta qaabaynta, iyadoo la kaashanayo qalabka caadiga ah waxay noqon kartaa qaabaynta extrusion ama qaabaynta duritaanka;Waxay leedahay heerka crystallization degdeg ah iyo dheecaan wanaagsan, iyo heerkulka caaryada waa yar yahay
Jihada wax ka beddelka ee PBT
1. Wax ka beddelka hagaajinta
In PBT-ga lagu daray fiber galaas ah, fiber galaas iyo PBT resin bonding xoog waa wanaagsan yahay, in xabagta PBT ku daray qadar gaar ah oo fiber galaas ah, ma aha oo kaliya in ay sii wadi karaan PBT resin caabbinta kiimikada, processing iyo faa'iidooyinka kale ee asalka ah, laakiin sidoo kale waxay yeelan kartaa a koror aad u weyn oo ku yimid sifooyinkiisa makaanikada, oo ay ka adkaadaan dareen-celinta resin-ka ee PBT.
2. Wax ka beddelka ololka
PBT waa polyester caraf udgoon, oo aan lahayn olol dib u celin, ololkiisu waa UL94HB, kaliya ka dib marka lagu daro ololka celiska, wuxuu gaari karaa UL94V0.
Dib-u-celinta ololka sida caadiga ah loo isticmaalo waxay leeyihiin bromide, Sb2O3, fosfide iyo chloride halogen flame retardants, sida ugu badan waa toban bromine biphenyl ether, ayaa PBT ugu weyn, ololka dib u celisa, laakiin ilaalinta deegaanka awgeed, wadamada Yurub waxay muddo dheer mamnuuceen isticmaalka, Xisbiyadu waxay raadinayaan beddelka, laakiin ma laha faa'iido waxqabad ayaa ka badan toban beddelka bromine biphenyl ether.
3. Wax ka beddelka daawaha isku dhafka ah
Ujeedada ugu weyn ee PBT ay ku dhex milmay polymers kale waa in la wanaajiyo awoodda saamaynta muuqata, wanaajinta qallafsanaanta ay sababto yaraynta qaabaynta, iyo hagaajinta caabbinta kulaylka.
Isku darka ayaa si weyn loo isticmaalaa in wax laga beddelo gudaha iyo dibaddaba.polymers-ka ugu muhiimsan ee loo isticmaalo isku-darka PBT waa PC, PET, iwm. Alaabta noocan ah waxaa inta badan loo adeegsadaa baabuurta, elektiroonigga iyo qalabka korontada.Saamiga fiber-ka galaasku wuu ka duwan yahay, goobtiisa codsiguna sidoo kale wuu ka duwan yahay.
Codsiyada ugu muhiimsan ee alaabta PBT
1. Qalabka elegtarooniga ah
Ma jiro fiyuuska fiyuuska, beddelka elektiroonigga ah, beddelka dib-u-celinta, qalabka guriga, isku-xirka, iwm.
2. marawaxada kulaylka
Fiilada muraayadda ee la xoojiyay PBT waxaa inta badan loo isticmaalaa marawaxadaha kulaylka, marawaxada kuleylka ayaa lagu dhejiyaa mashiinka wakhti dheer si ay u caawiso kuleylka kulaylka, sifooyinka jireed ee shuruudaha caaggu waxay leeyihiin caabbinta kulaylka, ololka, xakamaynta iyo xoogga farsamada, PBT waa Caadi ahaan qaab 30% fiber ah ayaa lagu dabaqaa marawaxada kulaylka ee ka baxsan fareeshka iyo shafka gariiradda daabka marawaxad.
3. Qaybaha korantada
Fibre-glaas ee lagu xoojiyay PBT waxa kale oo loo istcimaalaa beddelka, isu-gudbida gudaha usha gariiradda, guud ahaan PBT oo lagu daray fiber 30% irbad samaynta.Qalabka jireed ee loo baahan yahay ee shafka gariiradda waxaa ka mid ah dahaarka, caabbinta kulaylka, caabbinta alxanka, dareeraha iyo xoogga, iwm. Qalabka ku habboon waa fiber GLASS oo lagu xoojiyay PBT, GLASS FIBER la xoojiyay PA6, GLASS FIBER xoojiyay PA66, iwm.
4. Ashaqootiveqaybo
A. Qaybaha dibadda: inta badan bamper baabuurka (PC/PBT), gacanta albaabka, shabag geeska, engine kulaylinta sii daayo cover daloolka, qolof daaqadda baabuur, fayras, cover silig, cover wheel sanduuqa qalabka gudbinta baabuurta, iwm.
B. Qaybaha gudaha: inta badan waxaa ka mid ah brace endoscope, bracket masar iyo nidaamka xakamaynta;
C, qaybaha korantada ee baabuurta: tuubada gariiradda gariiradda shideysa baabuurta iyo xirayaasha korantada ee kala duwan, iwm.
Isla mar ahaantaana, waxaa sidoo kale lagu dabaqi karaa dallacaadda qoryaha baabuurta tamarta cusub.
5. Qalabka makaanikada
Qalabka PBT waxaa sidoo kale si ballaaran loogu isticmaalaa cajalad duubista suunka suunka, daboolka kombiyuutarka, meerkuriga lampshade, daboolka birta, qaybaha mashiinka dubista iyo tiro badan oo qalab ah, CAM, badhanka, guryaha saacadaha elektaroonigga ah, qaybaha kamaradaha (oo leh kulayl, shuruudaha dib u dhigista dabka )
