Thaum lub sijhawm ua haujlwm ntawm cov hlau extrusion hydraulic xovxwm, bolts qee zaum poob thiab poob rau hauv lub tog raj kheej hydraulic, ua rau khawb loj ntawm lub plunger phab ntsa. Tom qab teeb meem tshwm sim, txoj hauv kev ib txwm tsis tuaj yeem ua tiav kev kho ntawm qhov chaw txhua. Nws tsuas tuaj yeem raug tshem tawm thiab xa mus rau cov chaw tsim khoom los kho cov vuam lossis hloov pauv. Raws li tsis muaj kev hloov pauv cov khoom seem, lub sijhawm rov tsim cov khoom lossis rov qab mus rau lub Hoobkas kho yog tsis tuaj yeem tswj tau. Kev ncua sijhawm ntev yuav ua rau muaj kev lag luam poob nyiaj ntau rau lub tuam txhab, thiab tib lub sijhawm, nws tseem yuav them tus nqi ua tiav lossis kho tus nqi. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev tsim khoom txuas ntxiv ntawm cov tuam txhab, nws yog qhov tsim nyog los nrhiav kev yooj yim, nrawm, yooj yim thiab muaj txiaj ntsig kev kho kom zoo los daws teeb meem cov cuab yeej siv, txo qis kev ua haujlwm ntawm lub tuam txhab thiab txo nqi kev saib xyuas. Muaj peev xwm siv cov khoom sib xyaw polymer rau kev kho ntawm qhov chaw
Cov kauj ruam:
1. Ci cov khoom uas tau khawb nrog cov pa oxygen-acetylene nplaim hluav taws (tswj qhov kub thiab zam qhov nplaim nplaim taws), thiab ci cov roj uas tau nkag rau saum cov hlau txhua xyoo puag ncig kom txog thaum tsis muaj lub txim taws.
2. Nto ntu ntu nrog lub kaum ntse ntse sib tsoo, thiab zom nws mus rau qhov tob ntawm 1 hli lossis ntau dua, thiab zom zawj raws cov phab ntsa sab nrauv ntawm lub tog raj kheej, nyiam dua qhov dovetail zawj. Laum qhov ntawm ob qho kawg ntawm qhov khawb kom tob dua thiab hloov pauv lub zog.
3. Siv cov paj rwb nqus hauv cov acetone lossis cov tshuaj ethanol kom huv si.
4. Siv cov khoom kho kom haum thiab zoo ib yam rau qhov khawb qhov chaw; thawj txheej yuav tsum yog nyias, tusyees thiab npog tag nrho qhov khawb kom ntseeg tau tias qhov ua tau zoo tshaj plaws ntawm cov khoom thiab cov hlau, thiab tom qab ntawd siv cov khoom siv rau tag nrho qhov chaw kho thiab nias dua. Ua kom ntseeg tau tias cov khoom tau ntim thiab mus txog qhov xav tau tuab kom nws siab dua me ntsis saum npoo ntawm cov phab ntsa sab nrauv ntawm lub tog raj kheej.
5. Nws siv sijhawm 24 teev rau cov khoom siv kom ua tiav ntau yam khoom ntawm 24 ° C. Txhawm rau txuag sijhawm, qhov kub tuaj yeem nce los ntawm lub teeb halogen. Txhua txhua 11 ° C qhov kub nce ntxiv yuav txo lub sijhawm kho ib nrab. Qhov ntsuas kub zoo tshaj yog 70 ° C.
6. Tom qab cov khoom siv tau khov kho, siv cov pob zeb zoo los yog cov nplais los kho thiab qib cov khoom uas siab dua li cov phab ntsa sab nrauv ntawm lub tog raj kheej, thiab kev tsim kho tiav.
