Ⅰ. Tswv yim
ABS cov khoom, lub npe hu ua -butadiene-styrene copolymer, yog cov khoom siv thermoplastic engineering yas. Nws muaj kev ua tau zoo, suav nrog kev siv tshuab zoo heev, zoo toughness, hnav tsis kam, yooj yim ua thiab molding zog, yog li nws tau siv dav hauv ntau yam kev lag luam.
Ⅱ. Kev ua
Kev ua cov ntawv yas ABS feem ntau suav nrog preheating, yas molding, txias thiab txiav cov kauj ruam. Nyob rau hauv lub preheating theem, ABS yas ntawv yog rhuab mus rau ib tug tej yam kub, thiaj li hais tias nws mus txog ib tug zoo yas lub xeev; nyob rau hauv lub suction molding theem, los ntawm lub tshuab nqus tsev suction molding tshuab yuav preheated ABS daim ntawv adsorption nyob rau hauv pwm, tsim ntawm qhov yuav tsum tau cov duab; nyob rau hauv lub txias theem, los ntawm cov khoom cua txias yuav nqus molding tom qab txias ntawm ABS cov ntaub ntawv curing, thiaj li yuav tswj nws cov duab; thiab thaum kawg, nyob rau theem txiav, yuav tsum txias raws li qhov xav tau loj thiab cov duab ntawm ABS cov khoom txiav. Thaum kawg, nyob rau theem txiav, cov khoom siv ABS txias yog txiav raws li qhov xav tau loj thiab cov duab.
Ⅲ. Kev siv tshuab
ABS yas ntawv ua tshuab feem ntau suav nrog thermoforming thiab txias molding ob yam. Thermoforming yog nyob rau hauv kub kub ABS cov ntaub ntawv rau hauv lub cev xav tau, thiab ces kho tom qab txias; txias molding yog nyob rau hauv chav tsev kub los ntawm cov neeg kho tshuab siab rau ABS cov ntaub ntawv rau hauv qhov yuav tsum tau cov duab. Cov cuab yeej ua haujlwm ntawm ABS cov ntawv yas feem ntau suav nrog cov khoom siv ua ntej, cov khoom siv yas nqus, cov khoom siv txias thiab cov cuab yeej txiav, thiab lwm yam. Preheating cov cuab yeej siv los ua cov khoom siv ABS rau hauv cov duab uas yuav tsum tau ua, thiab tom qab ntawd txiav nws raws li qhov xav tau loj thiab cov duab. Cov khoom siv preheating yog siv los ua kom sov cov khoom ABS rau qee qhov kub, kom nws muaj cov yas zoo; suction molding khoom siv los preheat ABS cov khoom adsorption hauv pwm los ua cov duab xav tau; Cov khoom siv cua txias yog siv los nqus molding tom qab ABS cov khoom txias thiab kho kom nws cov duab; Cov cuab yeej txiav yog siv los ua kom txias ABS cov khoom raws li qhov xav tau loj thiab cov duab ntawm tsib ABS suction molding yas ntawv. Ua cov teeb meem thiab kev daws teeb meem.
Ⅳ. Cov txheej txheem suction molding tuaj yeem tshwm sim
⑴ Warping deformation:
ABS yas nyob rau hauv cov txheej txheem cua sov yog feem ntau ua rau warping deformation, tshwj xeeb tshaj yog nyob rau hauv ntug ib feem. Qhov no yuav yog vim qhov kub tsis sib xws los ntawm qhov tsis txaus. Txoj kev daws teeb meem tuaj yeem hloov kho cov cua sov thiab lub sijhawm, lossis siv cov kev tiv thaiv tshwj xeeb warping.
⑵ Cua npuas thiab qhov
Thaum lub sij hawm blister molding txheej txheem, yog tias muaj huab cua npuas los yog qhov nyob rau hauv cov yas, nws yuav cuam tshuam rau cov tsos thiab zoo ntawm cov khoom. Qhov no tuaj yeem tshwm sim los ntawm impurities hauv cov khoom siv raw lossis roj tso tawm thaum lub sijhawm cua sov. Cov kev daws teeb meem tuaj yeem siv cov ntaub ntawv zoo raw khoom, tswj qhov kub thiab txias thaum lub sij hawm cua sov txheej txheem, nrog rau kev ntsuas kom tsim nyog.
⑶ Lub ntsej muag tsis zoo nrog qhov tsis xws luag
Tej zaum yuav yog vim cov pwm saum npoo tsis tiaj tus lossis qhov kub tsis sib xws thaum lub sijhawm cua sov, qhov kev daws teeb meem tuaj yeem kho cov pwm saum npoo, kho cov cua sov thiab lub sijhawm, nrog rau kev ntsuas kom tsim nyog txias.
⑷ Qhov loj me tsis raug
Tej zaum nws yuav yog vim qhov tsim tsis tsim nyog ntawm cov pwm los yog lub shrinkage thaum lub sij hawm cua sov txheej txheem.
⑸ Xim txawv
Tej zaum nws yuav tshwm sim los ntawm qhov tsis ruaj tsis khov ntawm cov khoom siv raw lossis kev tswj qhov kub tsis zoo thaum cua sov. Qhov kev daws teeb meem tuaj yeem yog kev siv cov khoom siv ruaj khov, tswj qhov kub thiab txias hauv cov txheej txheem cua sov thiab, nrog rau kev hloov xim.
Nyob rau hauv luv luv, ABS yas absorbing txheej txheem nyob rau hauv cov ntaub ntawv thov tej zaum yuav ntsib warping thiab deformation, npuas thiab qhov, nto tsis du, tsis raug loj thiab xim txawv thiab lwm yam teeb meem. Los ntawm kev txhim kho cov txheej txheem tsis zoo, txhim kho pwm tsim thiab xaiv cov khoom siv zoo, cov teeb meem no tuaj yeem daws tau zoo los txhim kho cov khoom zoo thiab cov khoom zoo.
Ⅴ. Kev siv thaj chaw thiab kev loj hlob zoo
Lub khw muag khoom ntawm ABS blister yas ntawv yog dav heev. Ntawm qhov tod tes, vim qhov ua tau zoo ntawm ABS cov ntaub ntawv thiab cov yam ntxwv ua haujlwm yooj yim, nws daim ntawv thov hauv ntau qhov chaw yuav dhau los ua ntau dua; ntawm qhov tod tes, nrog rau kev txhim kho ntawm ib puag ncig kev paub thiab lub zog tshiab, biomedical, kev tsim khoom ntse thiab lwm qhov chaw tsim tawm ntawm kev txhim kho cov ntawv thov tshiab thiab cov khoom zoo ib puag ncig ntawm ABS cov ntaub ntawv yuav txhim kho ntau dua. Yog li, nws tuaj yeem kwv yees tias kev lag luam zeem muag ntawm ABS yas ntawv yog dav heev.
Tam sim no, kev tshawb fawb ntawm ABS blister yas ntawv feem ntau yog tsom rau nws cov thev naus laus zis ua haujlwm, thaj chaw thov thiab teeb meem ib puag ncig. Hais txog kev siv tshuab, cov kws tshawb fawb tab tom nrhiav kev ua haujlwm tshiab uas muaj txiaj ntsig zoo dua thiab ib puag ncig zoo; nyob rau hauv cov nqe lus ntawm daim ntawv thov, cov kws tshawb fawb tab tom tshawb nrhiav cov ntawv thov tshiab ntawm ABS cov ntaub ntawv hauv lub zog tshiab, biomedical, kev tsim khoom ntse thiab lwm yam haujlwm tshiab; Nyob rau hauv cov nqe lus ntawm ib puag ncig teeb meem, cov kws tshawb fawb tab tom tsim cov ntaub ntawv ABS degradable thiab siv thev naus laus zis kom paub txog kev rov ua dua ntawm cov peev txheej thiab kev tiv thaiv ib puag ncig. Nws tuaj yeem kwv yees tias nrog kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis thiab kev hloov pauv hauv kev xav tau ntawm kev lag luam, kev tshawb fawb ntawm ABS blister yas ntawv yuav tau txais kev txhim kho ntau dua.
