Cov txheej txheem nyob rau hauv uas txheej saum npoo ntawm txheej hloov pauv los ntawm cov kua los yog hmoov lub xeev rau amorphous khoom zaj duab xis yog hu ua txheej txheem tsim txheej txheem ntawm acrylic cob, lossis cov khoom ua si propionic acid cob. Acrylic cob feem ntau cuam tshuam txog qhov kev hloov kho, kev kub yaj, kev ua kom tsis haum, polymerization thiab lwm yam ntawm lub cev lossis tshuaj ntawm cov kuab tshuaj los ua cov zaj duab xis. Raws li cov txheej txheem sib txawv ntawm cov zaj duab xis, cov acrylic ntxig yuav tau muab faib ua cov yeeb yaj kiab tsis huv-ua hom thiab hla-txuas zaj duab xis-ua hom.
Muaj ntau txoj hauv kev kho kom zoo rau acrylic cob, feem ntau muab faib ua peb hom, uas yog ntuj tua, qhov kub kho thiab hluav taws xob tua.
Ua ntej: Ntuj tua (los yog kom qhuav ntuj) tsuas yog haum rau cov neeg tsis mloog lus acrylic cob, qhov kho tus kheej acrylic cob thiab catalyst polymerization acrylic cob. Kev kho qhov ceev ntawm cov zaj duab xis txheej yog ntsig txog huab cua kub, av noo thiab cua ceev. Feem ntau, qhov kub dua, qhov qis dua ntawm cov av noo. Qhov zoo dua ntawm cov cua hauv cua, qhov kho dua sai. Cov duab hluav taws xob ultraviolet nyob rau hauv lub hnub tuaj yeem txhawb txoj kev kho kom haum ntawm oxidative polymerization hom acrylic cob. Kev tua kab tas mus li kuj muaj qhov yuav tsum tau ua kom huv ntawm huab cua thiab yuav tsum ua raws li kev tiv thaiv ib puag ncig.
Thib ob: Cov cua kub kho yog muab faib rau hauv kev yuam kom qhuav thiab ziab. Kev yuam ziab yog hais txog txheej txheej uas ziab kom qhuav los ntawm cua sov. Lub sijhawm shrinkage curing feem ntau yog qis dua, thaum 60-100 * C; ziab yog hais txog cua sov tsuas yog nyob ntawm qhov kub thiab txias Under-curing acrylic resin ua kom nws zoo rau hauv zaj duab xis, qhov kub feem ntau siab tshaj 120 ° C. Qhov kub cua kub hais txog qhov kub ntawm cov xim coated saum npoo lossis txheej txheej hauv qab, tsis yog qhov kub ntawm qhov chaw kom qhuav.
Nws muaj peb txoj kev cua sov: convection, hluav taws xob thiab hluav taws xob induction. Convection cua sov siv cua kub ua qhov nruab nrab. Nws muaj qhov zoo ntawm cov khaub ncaws cua sov thiab tswj qhov kub thiab txias. Nws yog qhov tsim nyog rau ziab cov khoom coated nrog zoo txheej zoo thiab ua kom pom tseeb. Qhov tsis zoo yog qhov ua kom sov li qeeb. Cov hluav taws xob cua sov feem ntau siv infrared thiab deb infrared, hluav taws xob tau ncaj qha rau ntawm qhov khoom thiab hloov mus rau lub zog cua sov, kom lub substrate thiab txheej tau kho nyob rau tib lub sijhawm, cim tau ceev ceev cua sov, siab ceev thermal, thiab cua sov tsis ncaj Cov. Kev siv hluav taws xob induction cua sov siv hluav taws xob ua hluav taws xob ua kom sov cov hlau qhov chaw. Nws yog tsiag ntawv los ntawm kev ua haujlwm siab thiab ua kom haum rau cov haujlwm me me hlau.
Thib peb: Hluav taws xob tua hluav taws xob yog qhov thev naus laus zis uas siv ultraviolet teeb thiab hluav taws xob kab teeb los kho cov xim.
