Ua ntej, cov txheej txheem ua kua nplaum tshwm sim los ntawm "thaiv phom"
Yog vim li cas tsom xam:
1, kua nplaum muaj ntau dhau impurities;
2, kev siv cov phom tsis zoo;
3, cov kua nplaum ntub dej, leveling tsis zoo.
Txoj kev daws teeb meem:
1, lim impurities;
2, xaiv cov phom phom zoo;
3, ntxiv cov additives tsim nyog los txhim kho nws cov wetting, leveling tus neeg sawv cev.
Ob, ntug tsis tuaj yeem nqus lossis ntsws
Yog vim li cas tsom xam:
1, blister, sab kub yog qis los yog lub tshuab nqus tsev kawm ntawv tsis txaus;
2, qhov kub tsis kam ntawm cov kua nplaum tsis txaus;
3, tom qab lub hlwv moulding, nyob rau hauv rooj plaub uas qhov kub tsis tau poob, lub siab yog rho.
Txoj kev daws teeb meem:
1, nce qhov kub thiab txias;
2, kev siv cov tshuaj tua kab mob;
3. Tom qab blister molding, qhov kub thiab txias yog txias rau hauv chav tsev kub los yog siab dua me ntsis ua ntej lub tshuab nqus tsev rho tawm.
3. Local foaming
Yog vim li cas tsom xam:
1, cov kua nplaum tsis sib xws, ua rau cov kua nplaum hauv zos tsawg, kom lub zog ntawm daim ntawv cog lus txo;
2, qhov teeb meem ntawm PVC zaj duab xis, PVC zaj duab xis muaj plasticizer, nyob rau hauv cov ntaub ntawv ntawm kev laus los yog tshav kub, plasticizer yog ib qho yooj yim rau migrate rau saum npoo, cuam tshuam rau lub zog ntawm daim ntawv cog lus;
3. Muaj teeb meem ntawm lub raj cua sov hauv lub tshuab blister, ua rau qhov kub tsis sib xws.
Txoj kev daws teeb meem:
1, kom deb li deb tau tshuaj tsuag tus nqi sib xws;
2, siv zoo PVC zaj duab xis;
3, kev tu lub sijhawm ntawm cov khoom siv.
4. Loj cheeb tsam foaming
Yog vim li cas tsom xam:
1, qhov kub los yog siab tsis ua raws li qhov yuav tsum tau ua, ua rau muaj kev nqus tsis raug;
2, tus nqi ntawm cov kua nplaum tsis txaus, cov tshuaj tsuag yog tsawg dua lossis cov phaj permeated;
3, lub sij hawm preheating tsis txaus (softening PVC zaj duab xis) los yog blister lub sij hawm (lub sij hawm molding) tsis txaus;
4, tom qab lub hlwv moulding, nyob rau hauv rooj plaub uas qhov kub tsis tau poob, lub siab yog rho.
5, lub tshav kub tsis kam ntawm cov kua nplaum nws tus kheej tsis txaus.
Txoj kev daws teeb meem:
1, nce qhov kub thiab txias;
2, nce tus nqi ntawm qhov loj me, xaiv cov phaj zoo;
3, nce lub sij hawm preheating los yog lub sij hawm blister;
4. Tom qab blister molding, qhov kub thiab txias yog txias rau hauv chav tsev kub los yog siab dua me ntsis thiab ces tshem tawm ntawm lub tshuab nqus tsev.
5. Siv 3-5 feem pua curing agent.
Tsib, tsis txaus stickiness
Yog vim li cas tsom xam:
1, qhov kev faib ua feem ntawm kev xa tawm ntawm cov yas nqus dej tsis sib xws;
2, sib txawv additives tshwm sim los ntawm.
Txoj kev daws teeb meem:
1. Tsim nyog kho lossis nce cov ntsiab lus lossis cov ntsiab lus ntawm PUD;
2, xyuas seb cov additives lossis additives ntxiv muaj cov tshuaj tiv thaiv tshwj xeeb, thiab ua cov kev sim ntau ntxiv kom ua tiav cov qauv zoo tshaj plaws ntawm cov yas nqus.
Rau, muaj pockmarks ntawm qhov chaw ntawm cov khoom
Yog vim li cas tsom xam:
1, qhov loj ntawm cov kua nplaum yog qhov loj, kev siv cov yeeb yaj kiab PVC nyias, yooj yim los tsim pitting, xws li pitting yog tus cwj pwm los ntawm kev tsis sib xws;
2, thaum siv cov tshuaj tua kab mob, cov tshuaj tua kab mob tsis tawg tag nrho;
3, qhov saum npoo ntawm lub phaj tsis raug kho kom huv si, lossis tom qab txau cov kua nplaum, lub rhiav plua plav yog loj, glued rau, qhov pitting point dispersion yog heev uneven, thiab qhov loj yog txawv;
4, viscosity ntawm cov kua nplaum yog loj heev, dispersion tsis sib xws;
5, lub viscosity ntawm cov kua nplaum yog me me dhau los yog cov ntsiab lus ntawm cov khoom tsis tshua muaj, ua rau lub phaj fuzz, cov ntsiab lus pitting feem ntau tshwm nyob rau hauv lub ces kaum ntawm qhov zawj, qhov thaiv tshwm;
6, huab cua siab ntawm rab phom tsis txaus, lub atomization tsis zoo;
7, cov kua nplaum tsis lim (qhov xwm txheej no yog hais txog: lub thoob ntawm cov kua nplaum siv thaum kawg, yog tias nws poob rau hauv cov khoom raug nyiag lossis cov khoom sib txuas, kom lim nrog lub lim).
Txoj kev daws teeb meem:
1, xaiv cov kua nplaum nrog cov khoom me me;
2, nrog tus neeg sawv cev kho, txuas ntxiv lub sijhawm sib xyaw, kom tus neeg saib xyuas tuaj yeem tawg tag nrho;
3. Ntxuav lub ntsej muag ntawm lub phaj ua ntej tshuaj tsuag, thiab lub rhiav kev txau yuav tsum tau muab cais tawm;
4, xaiv txoj cai viscosity ntawm cov kua nplaum los yog cov ntsiab lus siab ntawm cov kua nplaum;
5. Tom qab cov kua nplaum qhuav, nws tuaj yeem polished nrog cov ntawv xuab zeb zoo.
6, nce lub tshuab nqus tsev kawm ntawv, kho cov nyhuv atomization;
7, thaum siv, lim nrog lub lim.
