PBT engineering mapulasitiki, (polybutylene terephthalate), ali ndi ntchito yabwino kwambiri, yotsika mtengo, ndipo ali ndi kukonza kwabwino.Pamagetsi, zida zamagetsi, zida zamakina, zida zamagalimoto ndi zolondola ndi zina, zakhala zikugwiritsidwa ntchito kwambiri.
Makhalidwe a PBT yosinthidwa
(1) Makina abwino kwambiri, mphamvu zambiri komanso kukana kutopa, kukhazikika kwapang'onopang'ono komanso kukwawa pang'ono.Pansi pa kutentha kwakukulu, ntchitoyo imasintha pang'ono.
(2) Easy lawi retardant, ndi lawi retardant ali ndi ubwenzi wabwino, zosavuta kukhala anawonjezera mtundu ndi anachita mtundu wamoto retardant kalasi, akhoza kukwaniritsa zofunika za UL94 V-0 kalasi.Zakhala zikugwiritsidwa ntchito kwambiri mu zamagetsi ndi zamagetsi zamagetsi.
(3) Kukana kutentha, kukana kukalamba, kukana zosungunulira za organic.Mlozera wowonjezera wa kutentha wa UL umasungidwa mumitundu ya 120 ° C mpaka 140 ° C, ndipo onse amakhala ndi kukalamba kwakunja kwanthawi yayitali.
(4) Ntchito yabwino yopangira.Easy kuti yachiwiri processing ndi akamaumba processing, mothandizidwa ndi zida wamba akhoza extrusion akamaumba kapena jekeseni akamaumba;Ili ndi liwiro la crystallization mwachangu komanso madzi abwino, ndipo kutentha kwa nkhungu kumakhala kochepa
Kusintha kwa PBT
1. Kusintha kowonjezera
Mu PBT anawonjezera galasi ulusi, galasi CHIKWANGWANI ndi PBT resin bonding mphamvu ndi zabwino, mu PBT utomoni anawonjezera kuchuluka kwa galasi CHIKWANGWANI, osati kusunga PBT utomoni kukana mankhwala, processing ndi ubwino zina zoyambirira, komanso akhoza kukhala ndi Kuwonjezeka kwakukulu kwamakina ake, ndikugonjetsa kukhudzidwa kwa PBT resin notch.
2. Kusinthidwa kwamoto wamoto
PBT ndi crystalline onunkhira poliyesitala, popanda retardant lawi, moto retardant ndi UL94HB, pokhapokha kuwonjezera lawi retardant, akhoza kufika UL94V0.
Zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ndi bromide, Sb2O3, phosphide ndi chloride halogen retardants, monga momwe zilili ndi bromine biphenyl ether, zakhala PBT yaikulu, yolepheretsa moto, koma chifukwa cha chitetezo cha chilengedwe, mayiko a ku Ulaya akhala akuletsa kugwiritsa ntchito nthawi yaitali. maphwando akufunafuna m'malo, koma alibe ntchito mwayi wakhala oposa bromine biphenyl ether m'malo khumi.
3. Kusintha kwa aloyi osakanikirana
Cholinga chachikulu cha kusakanikirana kwa PBT ndi ma polima ena ndikuwongolera mphamvu zowoneka bwino, kuwongolera kusinthika kwapang'onopang'ono komwe kumadza chifukwa cha shrinkage ndikuwongolera kutentha.
Kusakaniza kumagwiritsidwa ntchito kwambiri kuti asinthe kunyumba ndi kunja.Ma polima osinthidwa omwe amagwiritsidwa ntchito pophatikiza PBT ndi PC, PET, ndi zina zotero. Zinthu zamtunduwu zimagwiritsidwa ntchito kwambiri pamagalimoto, zamagetsi ndi zida zamagetsi.Chigawo cha fiber magalasi ndi chosiyana, ndipo gawo logwiritsira ntchito ndilosiyana.
Ntchito zazikulu za PBT
1. Zida zamagetsi
Palibe chowotcha fuse, chosinthira chamagetsi, chosinthira choyendetsa kumbuyo, chogwirizira chamagetsi kunyumba, cholumikizira, ndi zina zambiri. PBT nthawi zambiri imawonjezeredwa 30% kusanganikirana kwa magalasi monga cholumikizira, PBT imagwiritsidwa ntchito kwambiri chifukwa cha makina, kukana zosungunulira, kupanga kukonza ndi mtengo wotsika.
2. Kuwotcha kutentha fani
Galasi CHIKWANGWANI analimbitsa PBT makamaka ntchito fani kutentha dissipation, zimakupiza kutentha dissipated amaikidwa mu makina kwa nthawi yaitali kuthandiza kutentha kutha, thupi katundu zofunika pulasitiki ndi kukana kutentha, flammability, kutchinjiriza ndi mphamvu makina, PBT ndi kawirikawiri mu mawonekedwe a 30% CHIKWANGWANI ntchito ngati zimakupiza kutentha dispation kunja chimango ndi zimakupiza tsamba koyilo kutsinde.
3. Zida zamagetsi
Glass fiber reinforced PBT imagwiritsidwanso ntchito ngati thiransifoma, relay mkati mwa shaft ya koyilo, nthawi zambiri PBT kuphatikiza ulusi wa 30% kupanga jakisoni.Zofunika zakuthupi za shaft ya koyilo zimaphatikizapo kusungunula, kukana kutentha, kukana kuwotcherera, fluidity ndi mphamvu, ndi zina. Zida zoyenera ndi GLASS CHIKWANGWANI cholimbitsa PBT, GLASS FIBER yolimbikitsidwa PA6, GLASS FIBER yolimbikitsidwa PA66, etc.
4. Azodziwikiratumagawo
A. Zigawo zakunja: makamaka bumper yagalimoto (PC/PBT), chogwirira chitseko, latisi yangodya, chivundikiro cha dzenje lotulutsa kutentha kwa injini, chipolopolo chamoto wazenera lagalimoto, fender, chivundikiro chawaya, bokosi la giya yotumizira galimoto, etc.
B. Zigawo zamkati: makamaka zikuphatikizapo endoscope brace, wiper bracket ndi control system valve;
C, zida zamagetsi zamagalimoto: chubu choyatsira moto ndi zolumikizira zosiyanasiyana zamagetsi, etc.
Panthawi imodzimodziyo, ikhoza kugwiritsidwanso ntchito ku chipolopolo chamfuti chamagetsi chamagetsi atsopano.
5. Zipangizo zamakina
PBT zakuthupi zimagwiritsidwanso ntchito kwambiri mu kanema wa tepi chojambulira lamba woyendetsa shaft, chivundikiro cha kompyuta, mercury lampshade, chivundikiro chachitsulo, zida zamakina ophika ndi zida zambiri, CAM, batani, nyumba zowonera zamagetsi, mbali za kamera (zotentha, zotsalira zamoto. )
