PBT yububiko bwa plastike, (polybutylene terephthalate), ifite imikorere myiza yuzuye, igiciro gito ugereranije, kandi ifite gutunganya neza. Muri elegitoroniki, ibikoresho by'amashanyarazi, ibikoresho bya mashini, ibikoresho byimodoka nibisobanutse nibindi bice, byakoreshejwe cyane.
Ibiranga PBT yahinduwe
. Mugihe cy'ubushyuhe bwo hejuru, imikorere irahinduka gake.
. Yakoreshejwe cyane mubikoresho bya elegitoroniki ninganda zamashanyarazi.
(3) Kurwanya ubushyuhe, kurwanya gusaza, kurwanya ibinyabuzima. Ubushyuhe bwa UL bwongerewe imbaraga bugumaho hagati ya 120 ° C kugeza 140 ° C, kandi byose bifite ibyiza byo hanze bishaje igihe kirekire.
(4) Imikorere myiza yo gutunganya. Byoroshye gutunganya icyiciro cya kabiri no gutunganya, hifashishijwe ibikoresho bisanzwe birashobora kuba ibishushanyo mbonera cyangwa gutera inshinge; Ifite umuvuduko mwinshi wo gutondeka no gutembera neza, kandi ubushyuhe bwububiko buri hasi
Icyerekezo cyo guhindura PBT
1. Guhindura iterambere
Muri PBT yongeyeho fibre fibre, fibre ibirahuri hamwe na PBT resin ihuza imbaraga nibyiza, muri resin ya PBT yongeyeho umubare munini wibirahure byibirahure, ntibishobora gusa gukomeza imiti ya PBT resin imiti, gutunganya nibindi byiza byumwimerere, ariko kandi irashobora kugira a ugereranije kwiyongera kwinshi mubikoresho byubukanishi, no gutsinda PBT resin notch sensitivite.
2. Guhindura ibirimi by'umuriro
PBT ni kristaline aromatic polyester, idafite flame retardant, flame retardant ni UL94HB, gusa nyuma yo kongeramo flame retardant, irashobora kugera kuri UL94V0.
Ikoreshwa rya flame retardants ifite bromide, Sb2O3, fosifide na chloride halogen flame retardants, nka benshi ni bromine icumi ya biphenyl ether, yabaye PBT ikomeye, irinda umuriro, ariko kubera kurengera ibidukikije, ibihugu byu Burayi bimaze igihe kinini bibuza gukoresha, gukoresha amashyaka arashaka umusimbura, ariko nta nyungu yo gukora yabaye arenze icumi ya bromine biphenyl ether.
3. Guhindura imvange
Intego nyamukuru yo kuvanga PBT nizindi polymers nugutezimbere imbaraga zidasanzwe, kunoza imiterere yintambara iterwa no kugabanuka, no kunoza ubushyuhe.
Kuvanga bikoreshwa cyane kubihindura murugo no mumahanga. Polimeri nyamukuru yahinduwe ikoreshwa muguhuza PBT ni PC, PET, nibindi. Ubu bwoko bwibicuruzwa bikoreshwa cyane cyane mumodoka, ibikoresho bya elegitoroniki nibikoresho byamashanyarazi. Ikigereranyo cya fibre fibre iratandukanye, kandi umurima wacyo uratandukanye.
Ibyingenzi byingenzi byibikoresho bya PBT
1. Ibikoresho bya elegitoroniki
Nta fuse yameneka, electromagnetic switch, gutwara inyuma ya transformateur, ibikoresho byo murugo ibikoresho, umuhuza, nibindi. PBT mubusanzwe yongewemo 30% fibre fibre ivanze nkumuhuza, PBT ikoreshwa cyane kubera imiterere yubukanishi, kurwanya solvent, gukora gutunganya no kugiciro gito.
2. Gushyushya umuyaga
Ikirahuri fibre ishimangirwa PBT ikoreshwa cyane cyane mumashanyarazi yo gukwirakwiza ubushyuhe, umuyaga ukwirakwiza ubushyuhe ushyirwa mumashini igihe kirekire kugirango ufashe gukwirakwiza ubushyuhe, ibintu bifatika byibisabwa bya plastiki bifite ubushyuhe bwo guhangana nubushyuhe, gucana, gukingirwa nimbaraga za mashini, PBT ni mubisanzwe muburyo bwa 30% fibre ikoreshwa nkumuriro wo gukwirakwiza ubushyuhe hanze yikariso na shitingi ya feri.
3. Ibikoresho by'amashanyarazi
Ikirahuri fibre ishimangirwa PBT nayo ikoreshwa nka transformateur, relay imbere muri shitingi, muri rusange PBT wongeyeho fibre 30%. Ibikoresho bisabwa bya shitingi ya coil harimo kubika, kurwanya ubushyuhe, kurwanya gusudira, gutembera n'imbaraga, nibindi. Ibikoresho bikwiye ni GLASS fibre ikomeza PBT, GLASS FIBER ishimangira PA6, GLASS FIBER ishimangira PA66, nibindi.
4. Automotiveibice
A. Ibice byo hanze: cyane cyane bumper yimodoka (PC / PBT), urugi rwumuryango, akazu kegereye inguni, moteri yubushyuhe bwo gusohora moteri, igikonoshwa cyimodoka yimodoka, fender, igifuniko cyinsinga, agasanduku k'ibikoresho byohereza imodoka, nibindi.
B. Ibice by'imbere: cyane cyane harimo endoscope brace, wiper bracket na sisitemu yo kugenzura valve;
C, ibice byamashanyarazi yimodoka: gutwika ibinyabiziga coil twist tube hamwe nu mashanyarazi atandukanye, nibindi.
Muri icyo gihe, irashobora kandi gukoreshwa kumashanyarazi yimbunda yimodoka nshya.
5. Ibikoresho bya mashini
Ibikoresho bya PBT bikoreshwa cyane mumashusho yerekana amashusho umukandara wa shitingi, igifuniko cya mudasobwa, itara rya mercure, igifuniko cyicyuma, ibyuma byo gutekesha hamwe nibikoresho byinshi, CAM, buto, inzu ya elegitoronike, ibikoresho bya kamera (hamwe nubushyuhe, ibisabwa byo kwirinda umuriro )
SIKOPOLYMERS 'Ibyiciro byingenzi bya PBT nibisobanuro byabo, nkibi bikurikira:
