ABS cov ntawv, ua tsaug rau lawv cov cuab yeej zoo heev thiab kev tsim qauv, tau siv dav hauv cov txheej txheem thermoforming xws li lub tshuab nqus tsev. Kev tswj xyuas qhov kub thiab txias yog qhov tseem ceeb heev, thiab cov yeeb yaj kiab- pab lub tshuab nqus tsev ua haujlwm twb paub lawm. Kev siv tau zoo siab -kub pob tshab zaj duab xis tuaj yeem txhim kho cov khoom ua tau zoo thiab cov tsos. Cov lus piav qhia ntxaws muaj nyob hauv qab no.
Lub thermoforming kub ntawm ABS nplooj ntawv yuav tsum tau kho raws li daim ntawv thickness thiab hloov hom. Rau cov nplooj ntawv ABS zoo tib yam, qhov kub thiab txias yog feem ntau ntawm 140 thiab 160 degree. Ib daim ntawv tuab 3 hli tuaj yeem ncav cuag lub xeev viscoelastic hauv qhov ntsuas kub no tom qab cua sov li 2 feeb, ua tau raws li qhov yuav tsum tau ua. Txawm li cas los xij, rau cov cua sov-stabilized ABS cov ntawv, vim qhov sib ntxiv ntawm cov stabilizers, qhov kub tuaj yeem nce mus rau 160-180 degree, nrog lub sijhawm cua sov hloov ntawm 10-20 vib nas this ib millimeter tuab. Tsis tshua muaj kub yuav ua rau cov ntawv tsis txaus toughness thiab yooj yim tawg thaum lub sij hawm tsim; Qhov kub thiab txias heev yuav ua rau daim ntawv sag, ua rau cov phab ntsa tsis sib xws, thiab txawm tias thermal degradation, cuam tshuam rau cov khoom ua haujlwm. Rau cov cua sov-resistant qib ABS siv nyob rau hauv complex ib feem, qhov kub thiab txias yuav tsum tau nruj me ntsis tswj nyob rau hauv lub sab sauv txwv, thaum shortening lub cua sov lub sij hawm kom tsis txhob deterioration ntawm cov khoom.
ABS cov ntawv tuaj yeem ua tiav thermoformed nrog zaj duab xis. Zaj duab xis- pab lub tshuab nqus tsev tsim tsis tsuas yog tiv thaiv qhov chaw ntawm ABS daim ntawv thaum lub sij hawm tsim, tiv thaiv khawb thiab kis kab mob, tab sis kuj muab cov khoom nrog ib tug tshwj xeeb tsos thiab muaj nuj nqi tom qab tsim. Piv txwv li, nyob rau hauv kev ua cov tsheb sab hauv thiab lub hnab ntim khoom, zaj duab xis - pab lub tshuab nqus tsev tsim tuaj yeem tsim cov xim hlau txhuam los yog textured, txo cov txheej txheem tha xim tom ntej. Txawm li cas los xij, yuav tsum tau them nyiaj rau qhov adhesion ntawm zaj duab xis thiab daim ntawv, thiab cov plua plav saum npoo yuav tsum tau ntxuav ua ntej kom tsis txhob muaj teeb meem xws li npuas thiab delamination tom qab tsim.
Cov yeeb yaj kiab pob tshab hauv qab no yog qhov tsim nyog rau siab - qhov kub thiab txias ntawm lub tshuab nqus tsev ntawm ABS cov ntawv:
Thawj hom yog PC pob tshab zaj duab xis. Nws muaj qhov kub zoo heev -kub tsis kam, nrog rau qhov kub tsis sib txawv ntawm qhov kub siab tshaj ABS thermoforming kub, thiab tuaj yeem tiv taus qhov kub siab ntawm 140-180 degree, ua rau nws ua tau zoo nrog ntau yam ABS cov txheej txheem thermoforming. Cov yeeb yaj kiab no muaj lub teeb xa hluav taws xob siab thiab muaj zog tiv thaiv, txhim kho lub zog saum npoo ntawm ABS cov khoom, thiab feem ntau yog siv rau hauv cov ntawv thov xws li hluav taws xob tiv thaiv npog thiab tsheb sab hauv vaj huam sib luag. Muaj ntau qhov piv txwv ntawm Douyin (TikTok) ntawm cov khoom tsim los siv ABS cov ntawv ua ke nrog PC zaj duab xis thermoforming, txhawb ntau yam xws li txhuam cov hlau thiab cov teebmeem gradient, muab ob qho tib si practicality thiab zoo nkauj.
Hom ob yog PET pob tshab zaj duab xis. Nws cov cua sov ua haujlwm tuaj yeem ncav cuag li 150 degree, uas zoo kawg nkaus ua rau cov thermoforming kub ntawm cov ntawv ABS zoo tib yam. Cov yeeb yaj kiab no muaj lub teeb xa hluav taws xob zoo, tshuaj lom neeg ua haujlwm zoo, thiab qhov ruaj khov. Nws tsis ntsws los yog deform yooj yim tom qab molding, kom ntseeg tau ib tug du nto rau ABS cov khoom. Nws yog feem ntau siv rau hauv thermoforming ntawm cov zaub mov-hu rau ABS ntim thiab cov khoom siv hluav taws xob, ua tau raws li kev nyiam huv huv thaum txhim kho cov khoom lag luam kom pom cov qauv sab hauv.
Hom thib peb yog PAP co-extruded pob tshab zaj duab xis. Hom zaj duab xis no siv polyolefin elastomers ua tus kheej- txheej nplaum thiab yog tsim los siv co- txheej txheem extrusion. Nws tiv taus cua sov tuaj yeem ncav cuag 160 degree, ua rau nws haum rau siab - kub molding ntawm tshav kub- ruaj khov ABS cov ntawv. Nws qhov txiaj ntsig tseem ceeb yog tias nws tsis muaj qhov seem, ua kom nruj rau ABS daim ntawv tom qab molding, thiab tsis muaj teeb meem delamination. Nws kuj tseem muaj lub teeb xa hluav taws xob zoo heev thiab txhim kho qhov khawb tsis kam ntawm cov khoom, ua rau nws tsim nyog rau cov thermoforming ntau lawm ntawm ABS cov khoom zoo nkauj thiab cov khoom vaj huam sib luag uas xav tau kev sib cuag.
Daim ntawv thov ntawm cov yeeb yaj kiab pob tshab no tso cai rau cov nplooj ntawv ABS los xyuas kom muaj kev ruaj ntseg thaum lub sij hawm thermoforming thaum nthuav cov khoom lag luam hloov mus rau ntau qhov chaw, muab ntau txoj hauv kev rau kev ua haujlwm ntawm ABS cov khoom.
