Qhov Tseem Ceeb thiab Kev Ua Haujlwm Zoo Ntawm Daim Ntawv Preheathing Kho Hauv Ntawv Khob Tshuab Ntau Lawm

1. Tus txheej txheem yooj yim thiab ua haujlwm ntawm kev kho reheating
Hauv cov txheej txheem ntau lawm ntawm cov ntawv khob tshuab, thawj kauj ruam yog mus rau preheat daim ntawv. Cov kauj ruam no zoo li yooj yim, tab sis nws yeej muaj cov ntsiab cai scient incology. Daim ntawv, cov ntawv tshwj xeeb siv los ua khob khob, feem ntau qhia txog qee qhov brittleness thiab qis dua ua ntej preheating, uas tsis muaj txiaj ntsig zoo rau kev molding tom ntej. Preheat kho cov kev hloov pauv kub rau saum npoo thiab sab hauv daim ntawv, tsis muaj zog ntawm cov ntawv lwg me me, ua rau cov fibers mos, thiab yog li txhim kho nws cov khoom siv yooj yim thiab vacuity.

Lub luag haujlwm tseem ceeb ntawm kev kho ua ntej yog xav txog hauv cov hauv qab no:

Txhim kho cov ntawv molding zoo: preheated ntawv yog yooj yim dua yuav tsum tau ua los ntawm pwm, txo cov teeb meem xws li cov khoom tawg, ua rau lub khob khob du thiab hauv qab.

Txhim kho ntau dua: preheating ceev nce cov moulding ceev ntawm daim ntawv hauv pwm, ua kom zoo sib zog ua ke, thiab kev txhim kho txhua yam tag nrho.

Txuag hluav taws: tsim nyog preheating yuav txo tau lub zog uas yuav tsum tau muaj nyob rau hauv cov txheej txheem ua kom moulding tom qab, ua tiav cov nyhuv ntawm lub zog txuag thiab emission txo.

Xyuas kom meej cov khoom sib xws: preheating kom ntseeg tau tias txhua lub pob ntawv yog nyob rau hauv tib lub xeev ua ntej nkag mus rau hauv lub moulding theem, yog li ua kom muaj qhov loj thiab cov duab ntawm cov khob ntawv.
2. Txhim kho cov tswv yim ua ntej preheating
Txhawm rau kom ntseeg tau tias daim ntawv preheating ua tiav cov nyhuv zoo tshaj plaws, nws yog qhov tsim nyog los ua kom zoo los ntawm ntau cov huab cua kub tswj, lub sijhawm preheating, thiab cov ntawv hloov tau.

Yog tswj cov huab cua kub kub: tsim nyog nce qib cua kub yog tus yuam sij kom ntseeg tau tias daim ntawv yog tag nrho preheated. Txawm li cas los xij, kev kub dhau heev yuav ua rau daim ntawv kom qhuav dhau-qhuav, cuam tshuam nws lub zog thiab kev khi; Qhov ntsuas kub tsawg dhau yuav ua rau tsis muaj txiaj ntsig zoo thiab ua tsis tiav cov nyhuv xav tau. Yog li ntawd, cov cua kub kub yuav tsum tau tswj cov tshuab hluav taws xob kom raug raws li cov hom ntawv cua sov raws li cov hom ntawv, tuab, thiab ntau lawm ceev kom pom cov kev pom kub zoo tshaj plaws.
Txhim kho lub sijhawm preheating: qhov ntev ntawm lub sijhawm preheating ncaj qha cuam tshuam cov nyhuv preheating. Yog tias lub sijhawm preheating yog luv heev, daim ntawv yuav tsis muaj tag nrho preheated, thaum yog tias lub sijhawm preheating ntev heev, nws yuav khib nyiab thiab txo cov khoom siv tau. Los ntawm kev sim thiab cov ntaub ntawv tsom xam, lub sijhawm tsim nyog tshaj plaws yog txiav txim siab kom ntseeg tau tias daim ntawv tsis nkim lub zog thaum tswj cov kev ua kom zoo.
Haum rau cov ntawv sau sib txawv: cov ntaub ntawv ntawm cov ntaub ntawv sib txawv ntawm cov huab cua sib txawv, thiab qee cov ntawv yuav tsum muaj qhov kub thiab txias dua rau lub xeev zoo tshaj plaws. Yog li ntawd, cov ntawv khob tshuab yuav tsum muaj ntau hom preheating kom yoog raws li qhov xav tau ntawm cov ntawv sib txawv thiab ua tiav prehishing preheating.
Ntxiv rau kev saib xyuas ntawm cov cuab yeej preheating xws li cov pa dej kub uas yuav tsum tau tu ncua thiab kev ua haujlwm tsis zoo thiab zam kev ua tsis tiav.
