Amapulasitiki obunjiniyela be-PBT, (i-polybutylene terephthalate), anokusebenza okuhle kakhulu okubanzi, inani eliphansi uma kuqhathaniswa, futhi anokucubungula okuhle kokubumba.Kwezinto zikagesi, izinto zikagesi, ezomshini, amathuluzi ezimoto nezinembayo neminye imikhakha, isetshenziswe kabanzi.
Izici ze-PBT eguquliwe
(1) Izakhiwo ezinhle kakhulu zemishini, amandla aphezulu kanye nokumelana nokukhathala, ukuzinza okuhle kwe-dimensional kanye nokukhasa okuncane.Ngaphansi kwezimo zokushisa eziphezulu, ukusebenza kushintsha kancane.
(2) I-retardant elula yomlilo, kanye ne-flame retardant inobudlelwane obuhle, kulula ukuthuthukisa uhlobo olungeziwe kanye nebanga lokuphendula lohlobo lwe-flame retardant, ingahlangabezana nezidingo zebanga le-UL94 V-0.Isetshenziswe kabanzi embonini kagesi kanye nekagesi.
(3) Ukumelana nokushisa, ukumelana nokuguga, ukumelana ne-organic solvent.Inkomba yokushisa ye-UL ethuthukisiwe igcinwa kububanzi obungu-120 ° C kuya ku-140 ° C, futhi bonke banokuguga okuhle kwangaphandle kwesikhathi eside.
(4) Ukusebenza kahle kokucubungula.Ukucubungula okulula kuya kwesibili nokucubungula ukubumba, ngosizo lwemishini evamile kungaba ukubunjwa kwe-extrusion noma ukubunjwa komjovo;Inezinga le-crystallization esheshayo kanye ne-fluidity enhle, futhi izinga lokushisa lesikhunta liphansi kakhulu
Ukuguqulwa kwesiqondiso se-PBT
1. Ukulungiswa okuthuthukisiwe
Ku-PBT yengeze i-glass fiber, i-glass fiber kanye ne-PBT resin bonding force kuhle, ku-resin ye-PBT yengeze inani elithile le-glass fiber, hhayi kuphela ingakwazi ukugcina i-PBT resin ukumelana kwamakhemikhali, ukucubungula nezinye izinzuzo zangempela, kodwa futhi ingaba ukwanda okulinganiselwe kwezakhiwo zayo zemishini, futhi kunqobe ukuzwela kwenotshi ye-PBT resin.
2. Ukuguqulwa kwe-flame retardant
I-PBT iyi-crystalline i-polyester enamakha, engenawo ukunqanda ilangabi, i-flame retardant yayo i-UL94HB, kuphela ngemva kokwengezwa kwe-flame retardant, ingafinyelela ku-UL94V0.
Amalangabi asetshenziswa ngokuvamile ane-bromide, i-Sb2O3, i-phosphide ne-chloride halogen retardants, njenge-bromine biphenyl ether eyishumi, bekuyi-PBT enkulu, i-flame retardant, kodwa ngenxa yokuvikelwa kwemvelo, amazwe aseYurophu asenesikhathi eside evimbela ukusetshenziswa, amaqembu afuna ukumiselela, kodwa angenayo inzuzo yokusebenza kube ngaphezu kwe-bromine biphenyl ether esikhundleni esingaphezu kweshumi.
3. Ukuguqulwa kwe-alloy yokuhlanganisa
Inhloso eyinhloko yokuhlanganisa i-PBT namanye ama-polymers ukuthuthukisa amandla omthelela angabonakali, ukuthuthukisa ukuwohloka kwe-warping okubangelwa ukuncipha kokubumba, nokuthuthukisa ukumelana nokushisa.
Ukuhlanganisa kusetshenziswa kabanzi ukuyiguqula ekhaya naphesheya.Ama-polymer ayinhloko ashintshiwe asetshenziselwa ukuhlanganisa i-PBT yi-PC, i-PET, njll. Lolu hlobo lwemikhiqizo lusetshenziswa kakhulu ezimotweni, ku-electronics namathuluzi kagesi.Ingxenye ye-fiber yengilazi ihlukile, futhi insimu yesicelo sayo nayo ihlukile.
Ukusetshenziswa okuyinhloko kwezinto ze-PBT
1. Imishini kagesi
Ayikho i-fuse breaker, i-electromagnetic switch, i-drive back transformer, isibambo sezinto zikagesi zasekhaya, isixhumi, njll. I-PBT ivamise ukungezwa ngo-30% we-glass fiber mixing njengesixhumi, i-PBT isetshenziswa kabanzi ngenxa yezakhiwo zemishini, ukumelana ne-solvent, ukwakha ukucubungula kanye nenani eliphansi.
2. Ifeni yokushisa ukushisa
I-Glass fiber eqinisiwe i-PBT isetshenziswa ikakhulukazi ku-fan yokushisa ukushisa, isiphephelo sokushisa ukushisa sibekwe emshinini isikhathi eside ukusiza ukuchithwa kokushisa, izakhiwo ezibonakalayo zezidingo zepulasitiki zinokumelana nokushisa, ukuvutha, ukufakwa kwe-insulation namandla omshini, i-PBT ngokuvamile kusimo se-fiber engu-30% esetshenziswa njengesiphephetha-moya esikhipha ukushisa ngaphandle kohlaka kanye neshafi yekhoyili ye-blade fan.
3. Izingxenye zikagesi
I-PBT ye-Glass fiber reinforced iphinde isetshenziswe njenge-transformer, idluliselwe ngaphakathi kwe-coil shaft, ngokuvamile i-PBT kanye nokwakhiwa komjovo we-fiber 30%.Izinto ezibonakalayo ezidingekayo ze-coil shaft zihlanganisa ukufakwa, ukumelana nokushisa, ukumelana ne-welding, fluidity namandla, njll. Izinto ezifanele ziyi-GLASS fiber reinforced PBT, i-GLASS FIBER eqinisiwe i-PA6, i-GLASS FIBER eqiniswe i-PA66, njll.
4. Aokwenzayoizingxenye
A. Izingxenye zangaphandle: ikakhulukazi ubhampa wemoto (i-PC/PBT), isibambo somnyango, ulethisi lwekhona, ikhava yembobo yokukhishwa kokushisa kwenjini, igobolondo lemoto yewindi lemoto, i-fender, ikhava yocingo, ibhokisi legiya lekhava yamasondo yemoto, njll.
B. Izingxenye zangaphakathi: ikakhulukazi zihlanganisa i-endoscope brace, i-wiper bracket kanye ne-valve yesistimu yokulawula;
C, izingxenye zikagesi zezimoto: ithubhu yekhoyili yokuthungela yezimoto nezixhumi ezihlukene zikagesi, njll.
Ngesikhathi esifanayo, ingasetshenziswa futhi kugobolondo lesibhamu sokushaja sezimoto ezintsha zamandla.
5. Imishini kagesi
Izinto ze-PBT zibuye zisetshenziswe kabanzi kushafti ye-video ye-tape recorder belt drive shaft, ikhava yekhompiyutha, i-mercury lampshade, isembozo sensimbi, izingxenye zomshini wokubhaka kanye nenani elikhulu lamagiya, i-CAM, inkinobho, izindlu zewashi le-elekthronikhi, izingxenye zekhamera (ezinokushisa, izidingo ze-flame retardant. )
I-SIKOPOLYMERS' Amabanga Ayinhloko e-PBT kanye nencazelo yawo, njengokulandelayo:
