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 ob.
(3).SA (SAN-styrene-acrylonitrile copolymer / Dali kua nplaum)
1. Kev ua haujlwm ntawm SA:
Chemical thiab Physical Properties: SA yog cov khoom siv tawv, pob tshab uas tsis yooj yim rau kev ntxhov siab sab hauv.Cov pob tshab siab, nws qhov kub thiab qhov cuam tshuam lub zog yog siab dua PS.Lub styrene tivthaiv ua rau SA nyuaj, pob tshab thiab yooj yim rau txheej txheem;acrylonitrile tivthaiv ua rau SA tshuaj thiab thermally ruaj khov.SA muaj zog load bearing muaj peev xwm, tshuaj lom neeg cov tshuaj tiv thaiv, thermal deformation kuj thiab geometric stability.
Ntxiv cov iav fiber ntau ntxiv rau SA tuaj yeem ua kom lub zog thiab thermal deformation tsis kam, thiab txo cov thermal expansion coefficient.Vicat softening kub ntawm SA yog li 110 ° C.Lub deflection kub nyob rau hauv load yog hais txog 100C, thiab lub shrinkage ntawm SA yog hais txog 0.3 ~ 0.7%.
2. Cov txheej txheem ntawm SA:
Kev ua haujlwm kub ntawm SA feem ntau yog 200-250 ° C.Cov khoom siv tau yooj yim nqus dej thiab yuav tsum tau qhuav rau ntau tshaj ib teev ua ntej ua.Nws fluidity yog me ntsis phem dua li ntawm PS, yog li qhov kev txhaj tshuaj siab kuj tseem me ntsis siab dua (txhaj tshuaj siab: 350 ~ 1300bar).Kev txhaj tshuaj ceev: kev txhaj tshuaj ceev yog pom zoo.Nws yog qhov zoo dua los tswj cov pwm kub ntawm 45-75 ℃.Kev ziab kom qhuav: SA muaj qee qhov hygroscopic yog tias khaws cia tsis raug.
Kev pom zoo kom qhuav yog 80 ° C, 2 ~ 4 teev.Melting kub: 200 ~ 270 ℃.Yog tias cov khoom tuab-walled tau ua tiav, cov khoom siv melting kub hauv qab qis qis tuaj yeem siv tau.Rau cov khoom siv ntxiv, pwm kub yuav tsum tsis pub tshaj 60 ° C.Lub tshuab cua txias yuav tsum tau tsim kom zoo, vim tias pwm kub yuav cuam tshuam ncaj qha rau cov tsos, shrinkage thiab khoov ntawm qhov.Khiav thiab rooj vag: Txhua lub rooj vag zoo tuaj yeem siv tau.Qhov loj ntawm lub rooj vag yuav tsum yog kom tsis txhob muaj streaks, me ntsis thiab voids.
3. Hom kev thov ntau yam:
Hluav taws xob (sockets, vaj tse, thiab lwm yam), cov khoom siv niaj hnub (cov khoom siv hauv chav ua noj, chav ua tub yees, TV hauv paus, lub thawv ntawv, thiab lwm yam), automotive kev lag luam (lub teeb lub thawv, lub teeb pom kev zoo, lub ntsuas hluav taws xob, thiab lwm yam), cov khoom siv hauv tsev (tableware, zaub mov. riam, thiab lwm yam.) thiab lwm yam), cov khoom siv tshuaj pleev ib ce ntim cov iav, cov dej lim dej thiab cov qhov rooj faucet.
Cov khoom siv kho mob (syringes, ntshav aspiration tubes, raum infiltration devices thiab reactors).Cov ntaub ntawv ntim khoom (cov khoom siv tshuaj pleev ib ce, lub tes tsho mem pleev di ncauj, lub raj mis mascara, lub kaus mom, lub kaus mom thiab lub taub hau, thiab lwm yam), cov khoom tshwj xeeb (cov khoom siv hluav taws xob pov tseg, txhuam cov hauv paus thiab txhuam hniav, nuv ntses iav, hniav hniav, txhuam hniav tuav, cwj mem tuav, cov twj paj nruag nozzles. thiab directional monofilaments), thiab lwm yam.
(4).ABS (super non-shredding kua nplaum)
1. ABS kev ua tau zoo:
ABS yog tsim los ntawm peb cov tshuaj monomers, acrylonitrile, butadiene thiab styrene.(Txhua lub monomer muaj cov khoom sib txawv: acrylonitrile muaj lub zog siab, thermal stability thiab tshuaj stability; butadiene muaj toughness thiab cuam tshuam tsis kam; styrene tau yooj yim ua, siab tiav thiab siab zog. nruam styrene-acrylonitrile theem thiab polybutadiene roj hmab dispersed theem.)
Los ntawm qhov pom ntawm morphological, ABS yog cov khoom siv amorphous nrog lub zog txhua yam thiab cov khoom zoo ntawm "tughness, toughness thiab steel".Nws yog amorphous polymer.ABS yog lub hom phiaj dav dav engineering yas nrog ntau hom thiab ntau yam kev siv.Nws tseem yog hu ua "general-purpose plastic" (MBS hu ua pob tshab ABS).Dej yog me ntsis hnyav dua), qis shrinkage (0.60%), dimensionally ruaj khov, thiab yooj yim rau cov duab thiab txheej txheem.
Cov khoom ntawm ABS feem ntau yog nyob ntawm qhov piv ntawm peb lub monomers thiab cov qauv molecular hauv ob theem.Qhov no tso cai rau qhov yooj yim ntawm cov khoom tsim, thiab tau ua rau ntau pua ntawm cov khoom zoo ABS sib txawv ntawm lub khw.Cov ntaub ntawv zoo sib txawv no muaj cov khoom sib txawv xws li nruab nrab mus rau qhov ua haujlwm siab, qis mus rau qhov kawg thiab siab kub ntswj, thiab lwm yam ABS cov khoom muaj kev ua tau zoo dua, cov yam ntxwv zoo li, tsis tshua nkag siab thiab ruaj khov zoo thiab muaj zog muaj zog.
ABS yog lub teeb daj granular lossis beaded opaque resin, tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis muaj dej nqus, nrog cov khoom zoo ntawm lub cev thiab cov khoom siv, xws li cov khoom siv hluav taws xob zoo, hnav tsis kam, qhov ruaj khov, tshuaj tiv thaiv thiab gloss, thiab lwm yam. mus ua thiab zoo li.Qhov tsis zoo yog huab cua tsis kam, tsis zoo cua sov, thiab flammability.
2.Cov yam ntxwv ntawm ABS
2.1 ABS muaj siab hygroscopicity thiab noo noo rhiab heev.Nws yuav tsum tau qhuav tag thiab preheated ua ntej molding (tsawg kawg 2 teev ntawm 80 ~ 90C), thiab cov ntsiab lus noo noo yuav tsum tau tswj hauv qab no 0.03%.
2.2 Lub yaj viscosity ntawm ABS resin tsis tshua muaj siab rau qhov kub thiab txias (sib txawv ntawm lwm cov amorphous resins).
Txawm hais tias qhov kev txhaj tshuaj kub ntawm ABS yog siab dua li ntawm PS, nws tsis tuaj yeem muaj cov cua sov xoob xws li PS, thiab tsis tuaj yeem siv qhov muag tsis pom cua sov los txo nws cov viscosity.Nws tuaj yeem nce ntxiv los ntawm kev ua kom cov ntsia hlau nrawm lossis txhaj tshuaj kom txhim kho nws cov fluidity.Qhov kev ua haujlwm dav dav yog 190-235 ℃.
2.3 Lub yaj viscosity ntawm ABS yog nruab nrab, uas yog siab dua li ntawm PS, HIPS, thiab AS, thiab yuav tsum tau txhaj tshuaj ntau dua (500 ~ 1000bar).
2.4 ABS cov khoom siv nruab nrab thiab kev kub ceev thiab lwm yam kev txhaj tshuaj kom ua tiav cov txiaj ntsig zoo.(Tshwj tsis yog tias cov duab yog qhov nyuaj thiab nyias-walled qhov yuav tsum tau txhaj tshuaj ntau dua), cov khoom nozzle txoj hauj lwm yog ua rau huab cua streaks.
2.5 ABS molding kub yog siab, thiab nws cov pwm kub feem ntau yog kho ntawm 25-70 ° C.
Thaum tsim cov khoom loj, qhov kub ntawm cov pwm ruaj khov (pem hauv ntej pwm) feem ntau yog li 5 ° C siab dua li cov pwm txav tau (rov qab pwm).(Pwm kub yuav cuam tshuam rau qhov kawg ntawm cov khoom yas, qhov kub thiab txias yuav ua rau qis dua)
2.6 ABS yuav tsum tsis txhob nyob twj ywm hauv qhov kub siab ntev ntev (yuav tsum tsawg dua 30 feeb), txwv tsis pub nws yuav yooj yim decompose thiab tig daj.
3. Cov ntawv thov ntau yam: tsheb (dashboards, cuab tam hatches, log npog, daim iav thawv, thiab lwm yam), tub yees, cov cuab yeej muaj zog (lub tshuab ziab plaub hau, tshuab ntxhua khaub ncaws, khoom noj khoom haus, tshuab txiav nyom, thiab lwm yam), xov tooj Case, ntaus ntawv ntaus ntawv , tsheb ua si xws li tsheb golf thiab dav hlau skis.
Txhawm rau txuas ntxiv, yog tias koj xav paub ntau ntxiv, thov koj xav tiv tauj peb.Baiyear yog lub koom haum loj loj ua ke nrog cov yas pwm tsim, txhaj tshuaj molding thiab cov ntawv hlau ua.Lossis koj tuaj yeem ua tib zoo mloog mus rau lub chaw xov xwm ntawm peb lub vev xaib official: www.baidasy.com , peb tseem yuav hloov kho cov xov xwm kev paub txog kev txhaj tshuaj molding kev lag luam.
