PBT khoom yog crystalline uas muaj ntxhiab polyester uas zoo heev tshuaj corrosion kuj, tsawg hygroscopicity thiab yooj yim ua. Txawm li cas los xij, cov khoom siv ntawm cov khoom siv ntawm cov khoom PBT unmodified feem ntau tsis zoo rau lwm yam xws li tshuab hlau, thiab tseem muaj kev tsis txaus siab xws li kub kub distortion, dimensional stability ntawm kev sov, thiab rhiab heev rau lub zog. Kev hloov ntawm PBT cov ntaub ntawv yog suav nrog iav fiber reinforced PBT thiab hluav taws kub PBT.
Cov nplaim hluav taws ntawm PBT cov ntaub ntawv yog UL94HB qib, thiab UL94V-0 tsuas yog ua tiav tom qab ntxiv nplaim hluav taws. Cov nplaim hluav taws kub ntau yog cov bromide, phosphide, chloride thiab antimony trioxide. Tam sim no, feem ntau ntawm cov nplaim hluav taws kub PBT yog qhov nplaim hluav taws kub uas nyob rau hauv cov decabromodiphenyl ether thiab antimony trioxide ntxiv.
Lub iav fiber reinforced PBT cov khoom muaj kev nplua nuj thiab qaug zog, ua kom sov, ua haujlwm tsis zoo, zoo hluav taws xob thiab dej tsis haum. Qingdao Zhongxin Huamei Lub tuam txhab cov neeg siv khoom muaj kev txhawb zog thiab nplhaib ntawm kev hloov kho raws li tus neeg yuav tsum tau ua. Tom qab hloov kho, qhov kub ntawm lub zog, kev hloov, qhov chaw ruaj khov thiab hluav taws retardancy yuav ua tau zoo dua tuaj, thiab cov nplaim taws PBT khoom siv dav siv hauv tsheb, hluav taws xob thiab hluav taws xob.
Cov ntsiab lus ntawm PBT cov ntaub ntawv tseem ceeb
1. Cov khoom vaj khoom tsev Lub zog tensile yog zoo li lub tensile modulus thiab nylon;
2. Kev sib txhuam coefficient yog me thiab nws tus kheej lub lubricating;
3. Cov dej tsis haum thiab hluav taws xob zoo;
5, ruaj ntseg zoo;
6. Tshuaj tiv thaiv zoo thiab cov roj ua haujlwm.
Lub ntsiab lus ntawm PBT cov ntaub ntawv tseem ceeb
1. Cov khoom siv hauv tshuab hluav taws xob
Tshem tawm kev ua haujlwm tsis muaj teebmeem, kev siv lub tshuab hloov hluav taws xob, kev hloov tsheb, kev siv khoom hauv tsev, kev sib txuas, thiab lwm yam .; PBT feem ntau ntxiv 30% iav fiber ntau blending li connector, PBT vim mechanical zog, hnyav ua haujlwm, zoo formability thiab nqi tsawg Widely saws.
2, kiv cua txias
Cov iav fiber reinforced PBT yog siv hauv cov kiv cua txias. Qhov txias ntxuam yog muab tso rau hauv lub tshuab ntev mus pab dissipate tshav kub. Nws yuav tsum muaj kev kub hnyiab, nplaim hluav taws, qhov hluav taws xob thiab lub zog ua haujlwm rau cov cuab yeej yas. PBT feem ntau yog 30% ntxiv. Siv ua ib lub voj voos txias txias sab nrauv thiab ib lub voj kaub khes taub.
3, cov khoom hluav taws xob
Cov iav fiber reinforced PBT kuj yog siv los ua ib qho kev sib txuas hauv cov twj thiab kev sib txuas, thiab feem ntau yog tsim los ntawm kev txhaj tshuaj molding ntawm 30% PBT. Cov khoom siv muaj xws li iav fiber reinforced PBT, cam fiber reinforced PA6, thiab iav fiber reinforced PA66.
4, lub tsheb teb
Ib qho, sab nraud: tsheb ciav hlau (PC / PBT), qhov rooj kov, kaum dej Geshan, cav kub tawm hood, qhov rai tsheb kas fes, fender, hlau txhaws, npog npog, tsheb kis kab lub npov Lub Hli;
b. Sab Nraud Cheebtsam: qhov kawg ntawm qhov kawg ntawm cov chaw nyob, lub plhaub wiper thiab kev tswj kav;
c. Automotive hluav taws xob qhov chaw: tsheb hluav taws ignition coils thiab ntau yam hluav taws xob connectors.
Nws kuj tuaj yeem siv rau kev them nyiaj phom nyob hauv cov tsheb tshiab.
5, khoom siv kho khoom siv
Cov ntaub ntawv PBT kuj tseem siv tau rau hauv cov ntaub ntawv kaw suab, xws li siv hlua khau, khoos phis tawj, thaiv npog hluav taws, npog tshuab hlau, thiab ntau ntau lub zog, cams, nyees khawm, hluav taws xob chaw nyob, . Tshav kub, hluav taws kub nyhiab)
