Feem ntau cov teeb meem luam ntawv ntawm cov tshuab luam ntawv
Thaum ua haujlwm ntawm lub tshuab luam ntawv, yog tias pom tias cov ntaub yuav raug dawb, tawg, tsis meej pem, luam ntawv smear, xim stains, thiab lwm yam, feem ntau yog tshwm sim los ntawm kev ua haujlwm tsis zoo lossis kev ua haujlwm, thiab kuj tuaj yeem tshwm sim los ntawm ntaub kho mob. Cov khoom siv tsis raug lossis tsis zoo nws tus kheej. Cov hauv qab no yuav qhia rau koj paubluam ntawv ntaubteeb meem ntawm cov tshuab luam ntawv:
1. Xim xim luam ntawv tsis sib xws (spots):Ib feem ntawmluam ntawvtau ua mottled zoo li daim tawv nqaij ntawm cov xuab zeb ntses. Qhov kev tsis zoo no feem ntau tshwm sim thaum lub viscosity ntawm cov xim muab tshuaj tsis tsim nyog, lub mesh ntawm lub vijtsam tsis raug xaiv, lossis thaj tsis sib xws.
2. Los ntshav (dissolving):Cov xim ntawm cov qauv luam tawm los ntshav tawm, cov qauv ntawm cov qauv tsis meej, thiab xim yog qhov muag plooj. Nws yog tshwm sim los ntawm qhov tsawg viscosity ntawm cov xim muab tshuaj, tsis tshua muaj tuab dye concentration, ntau npaum li cas ntawmluam ntawvmuab tshuaj txhuam los yog ntau dhau ntawm tus neeg sawv cev hygroscopic.
3. Xim-muab stains (xim-xim):stains tshwm sim los ntawm cov xim ntawm cov qauv luam tawm kis mus rau lwm qhov chaw. Feem ntau ntawm lawv tshwm sim thaum lub tshuab luam ntawv tsis huv, ziab tom qab luam ntawv tsis txaus los sib tshooj, lossis cov ntaub sib txuas nrog ib leeg hauv cov txheej txheem steaming. Hauv Nyij Pooj, qee lub tsev tsim khoom ua kom huv si hauv cov hlua khi siv txoj kev tswj hwm ntawm kev kho qhov nro ntawm cov ntaub.
4. Xim tsis txaus (desizing):uas yog, xim ntawm cov qauv ib feem yog tsis muaj. Nws feem ntau tshwm sim thaum cov xim muab tshuaj tsis tau ntxiv rau lub sijhawm, lub siab ntawm lub squeegee yog qhov tsis sib xws, qhov nyuaj ntawm lub squeegee yog qhov tsis tsim nyog, lub relay ntawm lub squeegee yog faulty, qhov saum npoo ntawm cov ntawv luam ntawv yog tsis sib xws, thiab cov viscosity ntawm lub squeegee. cov xim muab tshuaj txhuam thiab cov slurry tsis tsim nyog.
5. Cov qauv tsis zoo sib koom ua ke (sib koom luam ntawv):tus qauv overlaps los yog tsis phim (disengages) ntawm qhov sib koom ntawm tus qauv. Nws feem ntau tshwm sim los ntawm kev hloov kho tsis zoo ntawm txoj siv conveyor lossis kev hloov kho tsis raug ntawm lub rooj version, uas cuam tshuam rau qhov tseeb ntawm txoj haujlwm paj.
6. Misalignment ntawm tus qauv (crooked set, inaccurate set):Nws yog cov khoom luam tawm nrog cov qauv misaligned. Feem ntau ntawm lawv tshwm sim nyob rau hauv cov ntaub ntawv ntawm cov paj tsis raug, carving tsis zoo, thiab tsis zoo patching.
7. Ib nrab embrittlement:Ntawm cov ntaub ntawv luam tawm, cov chaw luam tawm nrog ib lossis ntau xim yog feem ntau puas, feem ntau yog vim kev siv cov tshuaj phem ntau hauv cov tshuaj pleev xim. Qhov teeb meem no kuj tuaj yeem pom nyob rau hauv qhov chaw tawm ntawm cov ntaub ntawv luam tawm.
