Iiplastiki zobunjineli bePBT, (i-polybutylene terephthalate), inomsebenzi ogqwesileyo obanzi, ixabiso eliphantsi ngokwentelekiso, kwaye inomsebenzi olungileyo wokubumba.Kwi-electronics, izixhobo zombane, izixhobo zoomatshini, izixhobo zemoto kunye nezichanekileyo kunye nezinye iindawo, zisetyenziswe ngokubanzi.
Iimpawu zePBT elungisiweyo
(1) Iipropathi ezigqwesileyo zomatshini, amandla aphezulu kunye nokumelana nokudinwa, ukuzinza okuhle komgangatho kunye nokunyuka okuncinci.Ngaphantsi kweemeko eziphezulu zokushisa, ukusebenza kutshintsha kancinci.
(2) I-retardant elula yomlilo, kunye ne-flame retardant inobudlelwane obuhle, kulula ukuphuhlisa uhlobo olongezelelweyo kunye nebakala lokuphendula i-flame retardant, inokuhlangabezana neemfuno zebakala le-UL94 V-0.Isetyenziswe ngokubanzi kumashishini ombane kunye nombane.
(3) Ukumelana nobushushu, ukumelana nokuguga, ukuxhathisa kwe-solvent ye-organic.Isalathiso sobushushu se-UL esiphuculweyo sigcinwa kuluhlu lwe-120 ° C ukuya kwi-140 ° C, kwaye zonke zinokwaluphala okuhle kwangaphandle kwexesha elide.
(4) Ukusebenza kakuhle kokusebenza.Easy ukuya yesibini processing kunye nokubumba processing, ngoncedo lwezixhobo eziqhelekileyo inokuba extrusion ukubumba okanye naliti ukubumba;Inesantya secrystallization ekhawulezayo kunye ne-fluidity elungileyo, kwaye iqondo lobushushu lokungunda liphantsi
Umkhombandlela wokuguqulwa kwePBT
1. Uphuculo lokuphucula
Kwi-PBT yongezelela i-fiber yeglasi, i-glass fiber kunye ne-PBT resin bonding force ilungile, kwi-resin ye-PBT yongeza inani elithile le-fiber yeglasi, kungekhona nje ukugcina i-PBT i-resin ukumelana nemichiza, ukuqhutyelwa phambili kunye nezinye iingenelo zangaphambili, kodwa nazo zinokuba nazo. ukwanda ngokwentelekiso kwiipropati zayo mechanical, kwaye boyise PBT resin inotshi uvakalelo.
2. Ukuguqulwa kwe-Flame retardant
I-PBT yi-crystalline i-polyester enevumba elimnandi, ngaphandle kwe-flame retardant, i-flame retardant yayo yi-UL94HB, kuphela emva kokongezwa kwe-flame retardant, inokufikelela kwi-UL94V0.
Iiretardants zomlilo ezisetyenziswa ngokuqhelekileyo zine-bromide, i-Sb2O3, i-phosphide kunye ne-chloride halogen retardants ye-flame retardants, njengeyona nto ininzi ishumi le-bromine biphenyl ether, ibe yeyona PBT enkulu, i-flame retardant, kodwa ngenxa yokhuseleko lokusingqongileyo, amazwe aseYurophu aye avala ixesha elide ukusetyenziswa, amaqela afuna ukutshintshwa, kodwa akukho nzuzo yokusebenza ibe ngaphezu kwe-bromine biphenyl ether substitutes engaphezu kweshumi.
3. Ukuguqulwa kwe-alloy yokudibanisa
Eyona njongo iphambili yokudityaniswa kwe-PBT kunye nezinye iipholima kukuphucula amandla efuthe elinotshini, ukuphucula i-warping deformation ebangelwa kukuncipha kokubumba, kunye nokuphucula ukumelana nobushushu.
Ukudibanisa kusetyenziswa ngokubanzi ukuyiguqula ekhaya nakwamanye amazwe.Iipolymers eziphambili ezilungisiweyo ezisetyenziselwa ukudibanisa i-PBT yi-PC, i-PET, njl njl. Olu hlobo lweemveliso lusetyenziswa kakhulu kwiimoto, i-electronics kunye nezixhobo zamandla.Umlinganiselo wefiber yeglasi uhlukile, kwaye insimu yesicelo sayo ihluke.
Usetyenziso oluphambili lwezixhobo zePBT
1. Izixhobo zombane
Akukho qhekeza i-fuse, i-electromagnetic switch, i-transformer ye-back back, i-handle appliance, i-connector, njl.
2. Ifeni yokukhupha ubushushu
Ifayibha yeglasi eyomeleziweyo ye-PBT isetyenziswa ikakhulu kwifeni yokutshatyalaliswa kobushushu, i-fan yokuchitha ubushushu ibekwe kumatshini ixesha elide ukunceda ukutshabalalisa ubushushu, iipropati ezibonakalayo zeemfuno zeplastiki zinokumelana nobushushu, ukutsha, ukugquma kunye namandla omatshini, i-PBT ngokwesiqhelo ikwimo ye-30% yefiber esetyenziswa njengefeni yokuchitha ubushushu ngaphandle kwesakhelo kunye ne-fan blade coil shaft.
3. Amacandelo ombane
Ifayibha yeglasi eyomeleziweyo yePBT ikwasetyenziswa njengesiguquli, ukulayishwa kwakhona ngaphakathi kwe-coil shaft, ngokubanzi i-PBT kunye ne-fiber 30% yokwenza inaliti.Iimpawu ezibonakalayo ezifunekayo ze-coil shaft ziquka ukugquma, ukuchasana nokushisa, ukuchasana kwe-welding, u-fluidity kunye namandla, njl. Izinto ezifanelekileyo zi-GLASS fiber reinforced PBT, i-GLASS FIBER iqiniswe i-PA6, i-GLASS FIBER iqiniswe i-PA66, njl.
4. Automotiveiinxalenye
A. Amalungu angaphandle: ubukhulu becala i-bumper yemoto (i-PC / PBT), isibambo somnyango, i-lattice yekona, i-injini yokukhutshwa kobushushu be-injini, i-shell yemoto yefestile yemoto, i-fender, i-wire cover, i-wheel cover car box gear transmission, njl.
B. Amalungu angaphakathi: ikakhulu abandakanya i-endoscope brace, i-wiper bracket kunye nevalve yenkqubo yokulawula;
C, iinxalenye zombane zeemoto: i-automotive ignition coil twist tube kunye nezihlanganisi zombane ezahlukeneyo, njl.
Kwangaxeshanye, inokuthi isetyenziswe kwiqokobhe lemipu yokutshaja yezithuthi zamandla amatsha.
5. Izixhobo zoomatshini
Izinto ze-PBT zikwasetyenziswa ngokubanzi kwi-video ye-tape rekhoda ibhanti yokuqhuba i-shaft, i-computer cover, i-mercury lampshade, i-iron cover, iinxalenye zoomatshini bokubhaka kunye nenani elikhulu lezixhobo, i-CAM, iqhosha, izindlu zokubukela i-elektroniki, iinxalenye zekhamera (ngobushushu, iimfuno ze-flame retardant. )
Amanqaku aphambili e-SIKOPOLYMERS e-PBT kunye nenkcazo yawo, ngolu hlobo lulandelayo:
