Ntawm no yog lub chaw xov xwm ntawm Baiyear txoj kev txhaj tshuaj molding kev lag luam.Tom ntej no, Baiyear yuav faib cov txheej txheem txhaj tshuaj molding rau hauv ob peb nqe lus los qhia txog kev txheeb xyuas cov ntaub ntawv raw ntawm cov txheej txheem txhaj tshuaj molding, vim tias muaj ntau cov ntsiab lus.Tom ntej no yog tsab xov xwm thib rau.
(14).PPO (polyphenylene ether)
1. Kev ua haujlwm ntawm PPO
Polyphenylene oxide yog poly-2,6-dimethyl-1,4-phenylene oxide, tseem hu ua polyphenylene oxide, English npe Polyphenyleneoxiole (hu ua PPO), hloov polyphenylene ether yog hloov nrog polystyrene lossis lwm yam polymers.Kev sib deev polyphenylene ether, hu ua MPPO.
PPO (NORLY) yog ib qho yas engineering nrog cov khoom zoo heev.Nws muaj hardness siab dua PA, POM thiab PC, siab mechanical zog, zoo rigidity, zoo tshav kub kuj (thermal deformation kub yog 126 ℃), thiab siab seem stability (shrinkage kub).tus nqi ntawm 0.6%), tsis tshua muaj dej nqus (tsawg dua 0.1%).Qhov tsis zoo yog tias nws tsis ruaj khov rau ultraviolet rays, tus nqi yog siab, thiab ntau npaum li cas me me.
PPO yog non-toxic, pob tshab, tsis tshua muaj txheeb ze ceev, thiab muaj zoo heev mechanical zog, kev nyuaj siab so, creep resistance, kub tsis kam, dej tsis kam, thiab dej vapor kuj.Cov khoom siv hluav taws xob zoo hauv ntau qhov kub thiab qhov sib txawv, tsis muaj hydrolysis, me me molding shrinkage, nplaim retardant thiab self-extinguishing, tsis zoo tiv thaiv inorganic acids, alkalis, aromatic hydrocarbons, halogenated hydrocarbons, roj, thiab lwm yam., yooj yim rau swell los yog Kev ntxhov siab tawg, qhov tsis zoo tseem ceeb yog cov dej tsis zoo, kev ua haujlwm nyuaj thiab kev tsim, feem ntau ntawm cov kev siv tau zoo yog MPPO (PPO blends lossis alloys), xws li PS hloov kho ntawm PPO, tuaj yeem txhim kho kev ua haujlwm zoo, txhim kho kev ntxhov siab tawg thiab cuam tshuam. kev ua haujlwm tsis kam, txo nqi, tsuas yog txo qis me ntsis hauv cov cua sov ua haujlwm thiab gloss.
Hloov cov polymers muaj xws li PS (xws li HIPS), PA, PTFE, PBT, PPS thiab ntau yam elastomers, polysiloxane, PS hloov PPO paraffin, cov khoom loj tshaj plaws, MPPO yog cov khoom siv dav siv dav siv ntau yam yas.Cov hom MPPO loj dua yog PPO / PS, PPO / PA / elastomers thiab PPO / PBT elastomer alloys.
2. Txheej txheem yam ntxwv ntawm PPO:
PPO muaj cov viscosity siab, cov dej tsis zoo, thiab cov txheej txheem ua haujlwm siab.Ua ntej ua, nws yuav tsum tau qhuav ntawm qhov kub ntawm 100-120 ° C rau 1-2 teev, molding kub yog 270-320 ° C, thiab pwm kub yog zoo dua tswj ntawm 75-95 ° C.ua.Nyob rau hauv cov txheej txheem ntawm cov yas npias yas, dav hlau ntws qauv (serpentine qauv) yog ib qho yooj yim uas yuav tsum tau ua nyob rau hauv pem hauv ntej ntawm lub nozzle, thiab cov ntws channel ntawm lub nozzle yog nyiam dua loj dua.
Yam tsawg kawg nkaus thicknesses li ntawm 0.060 mus rau 0.125 nti rau cov qauv moldings thiab 0.125 mus rau 0.250 nti rau cov qauv ua npuas ncauj, thiab flammability li ntawm UL94 HB rau VO.
3.Kev siv ntau yam:
PPO thiab MPPO tuaj yeem ua tiav los ntawm ntau txoj kev ua haujlwm xws li kev txhaj tshuaj molding, extrusion, tshuab moulding, molding, foaming thiab electroplating, nqus txheej, tshuab luam ntawv, thiab lwm yam., vim lub siab yaj viscosity thiab ua haujlwm kub.
PPO thiab MPPO feem ntau yog siv rau hauv cov khoom siv hluav taws xob, tsheb, khoom siv hauv tsev, cov khoom siv hauv chaw ua haujlwm thiab cov tshuab ua haujlwm, thiab lwm yam, siv MPPO rau kev tiv thaiv tshav kub, kev cuam tshuam, kev ruaj ntseg, khawb tsis kam, thiab tev tawm;
Paintability thiab hluav taws xob khoom: siv los ua lub tsheb dashboards, radiator grid, hais lus grilles, consoles, fuse thawv, relay thawv, connectors, log npog;dav siv nyob rau hauv hluav taws xob thiab hluav taws xob kev lag luam los tsim connectors, coil windings Spools, switching relays, tuning khoom, loj hluav taws xob qhia, txawv txawv capacitors, roj teeb accessories, microphones thiab lwm yam khoom.
Cov khoom siv hauv tsev yog siv rau TV, koob yees duab, video tapes, tape recorders, air conditioners, heaters, rice cookers and other parts.Nws tuaj yeem siv los ua cov khoom siv sab nraud thiab cov khoom siv rau cov tshuab luam ntawv, tshuab computer, tshuab luam ntawv, fax tshuab, thiab lwm yam. Tsis tas li ntawd, nws tuaj yeem siv los ua lub koob yees duab, timer, twj tso kua mis, blower plhaub thiab qhov chaw, twj tso kua mis, twj tso kua mis, valve lub cev, cov cuab yeej phais, sterilizer thiab lwm yam khoom siv kho mob.
Lub tshuab tshuab loj loj tuaj yeem siv rau cov khoom loj hauv tsheb xws li spoiler, bumpers, thiab low-foaming molding.Nws yog qhov tsim nyog rau kev tsim cov khoom lag luam loj nrog lub siab rigidity, qhov ntev stability, zoo heev lub suab nqus, thiab cov txheej txheem sab hauv, xws li ntau yam tshuab plhaub, hauv paus, sab hauv lub bracket thiab tsim muaj kev ywj pheej zoo, thiab cov khoom yog lub teeb yuag.
(15).PBT polybutylene terephthalate hmoov
1. Kev ua haujlwm ntawm PBT:
PBT yog ib qho nyuaj tshaj plaws engineering thermoplastics.Nws yog cov khoom siv semi-crystalline nrog cov tshuaj lom neeg zoo heev, cov khoom siv dag zog, hluav taws xob insulating zog thiab thermal stability.Cov ntaub ntawv no muaj kev ruaj ntseg zoo nyob rau hauv ntau yam ntawm ib puag ncig, thiab PBT muaj zog hygroscopic heev.Lub zog tensile ntawm unreinforced PBT yog 50MPa, thiab lub zog tensile ntawm iav additive hom PBT yog 170MPa.Ntau dhau iav additive yuav ua rau cov khoom ua nkig.
PBT;crystallization yog ceev heev, uas yuav ua rau khoov deformation vim tsis txias txias.Rau cov ntaub ntawv nrog iav additives, lub shrinkage nyob rau hauv tus txheej txheem kev taw qhia yuav txo tau, tab sis lub shrinkage nyob rau hauv cov kev taw qhia perpendicular rau cov txheej txheem yog yeej ib yam li cov ntaub ntawv zoo tib yam.
Cov khoom siv dav dav shrinkage yog nruab nrab ntawm 1.5% thiab 2.8%.Cov khoom uas muaj 30% iav additives poob ntawm 0.3% thiab 1.6%.Melting point (225% ℃) thiab kub deformation kub yog qis dua cov khoom siv PET.Vicat softening kub yog li 170 ° C.Cov iav hloov pauv kub (iav trasitiotemperature) yog nruab nrab ntawm 22 ° C thiab 43 ° C.
Vim lub siab crystallization tus nqi ntawm PBT, nws viscosity tsawg heev, thiab lub sij hawm voj voog ntawm cov khoom yas ua feem ntau yog tsawg.
2. Cov yam ntxwv ntawm PBT:
Kev ziab: Cov khoom no yooj yim hydrolyzed ntawm qhov kub thiab txias, yog li ziab ua ntej ua haujlwm yog qhov tseem ceeb.Pom zoo kom qhuav huab cua yog 120C rau 6 ~ 8 teev, lossis 150C rau 2 ~ 4 teev.
Cov av noo yuav tsum tsawg dua 0.03%.Yog tias ziab nrog hygroscopic desiccator, cov kev pom zoo yog 150 ° C rau 2.5 teev.Kev ua haujlwm kub yog 225 ~ 275 ℃, thiab pom zoo kub yog 250 ℃.Rau cov khoom siv tsis muaj zog, pwm kub yog 40 ~ 60 ℃.Cov cua txias channel ntawm cov pwm yuav tsum tau tsim kom zoo kom txo tau qhov khoov ntawm cov yas.Lub tshav kub dissipation yuav tsum ceev thiab txawm.
Qhov pom zoo txoj kab uas hla ntawm pwm txias channel yog 12mm.Kev txhaj tshuaj siab yog nruab nrab (txog 1500bar), thiab kev txhaj tshuaj yuav tsum ceev li sai tau (vim tias PBT solidifies sai heev).Khiav thiab rooj vag: Nws raug nquahu kom siv lub voj voog khiav kom nce kev sib kis ntawm lub siab (kev paub txog cov qauv: khiav txoj kab uas hla = yas ntu thickness + 1.5mm).
Ntau hom rooj vag siv tau.Cov neeg khiav dej kub kuj tuaj yeem siv tau, tab sis yuav tsum tau saib xyuas kom tsis txhob xau thiab degradation ntawm cov khoom.Lub rooj vag txoj kab uas hla yuav tsum nyob nruab nrab ntawm 0.8 ~ 1.0 * t, qhov twg t yog lub thickness ntawm cov yas.Yog tias nws yog lub qhov rooj nkag, qhov tsawg kawg nkaus txoj kab uas hla ntawm 0.75mm raug pom zoo.
3.Kev siv ntau yam:
Cov khoom siv hauv tsev (cov khoom siv ua zaub mov, cov khoom siv lub tshuab nqus tsev, cov kiv cua hluav taws xob, lub tshuab ziab plaub hau, cov khoom siv kas fes, thiab lwm yam), cov khoom siv hluav taws xob (switches, lub cev muaj zog, lub thawv fuse, lub computer keyboards, thiab lwm yam), automotive Industrial (radiator grilles, lub cev panels, log npog, qhov rooj thiab qhov rais Cheebtsam, thiab lwm yam.
Muaj kev paub ntau yam tau qhia hauv cheeb tsam no.Yog xav paub ntxiv, Baiyear yuav hloov kho nws sai li sai tau.Peb yuav ib txwm hloov kho cov ntaub ntawv yas, kev txhaj tshuaj molding ua, kev txhaj tshuaj molding cov cuab yeej qhia, pwm tsim, pwm carving, pwm ua cov cuab yeej taw qhia, ntawv hlau ua, Kev paub xov xwm ntawm kev faib lub thawv ntau lawm, hlau thawv ntau lawm, cov ntawv hlau ua cov cuab yeej taw qhia, waterproof junction box, waterproof qhov rais cover, thiab lwm yam Yog hais tias koj xav nyob rau hauv cov kev paub saum toj no, koj tuaj yeem tiv tauj kuv txhua lub sijhawm, kuv yuav zoo siab los pab koj thiab tos ntsoov rau koj tuaj txog.
