Txhais thiab cov ntaub ntawv ntawmntawv xuab zebthiabdaim ntaub xuab zeb
Sandpaper yog cov cuab yeej sib tsoo nto, haum rau kev sib tsoo thiab sib tsoo ntawm cov ntoo, hlau, yas thiab lwm yam ntaub ntawv. Nws feem ntau yog siv cov khoom abrasive glued rau cov ntaub ntawv raws li daim ntawv, thiab feem ntau yog siv rau kev sib tsoo thiab tshuab sib tsoo.
xuab zeb daim ntaub yog ib yam ntawm abrasive cuab yeej ua los ntawm woven daim ntaub puag cov ntaub ntawv, nws substrate yog kuj tawv, haum rau sib tsoo complex nto, xws li nkhaus nto, convex nto, concave thiab lwm qhov chaw. Nws tsis yooj yim rau deform thiab muaj kev hnav zoo.
Qhov thib ob, qhov sib txawv ntawm cov ntawv xuab zeb thiab cov ntaub xuab zeb
1. Cov khoom sib txawv
Sandpaper yog siv los ua raws li cov ntawv hauv paus, thiab cov ntaub xuab zeb yog siv los ua cov ntaub ntawv hauv paus. Qhov sib txawv tseem ceeb tshaj plaws los ntawm qhov sib txawv ntawm cov substrate no yog qhov sib txawv ntawm lub zog: cov ntawv xuab zeb ua los ntawm cov ntawv raws li cov khoom siv hauv paus tsis muaj zog, thiab cov ntaub emery siv cov ntaub braided raws li cov khoom siv hauv paus, uas muaj lub zog siab.
2. Kev siv sib txawv
Sandpaper yog tsim rau kev sib tsoo thiab sib tsoo, thaum cov ntaub xuab zeb tsim nyog rau kev ua haujlwm nyuaj, xws li nkhaus, concave thiab lwm yam.
3. Sib txawv qhov tseeb
Qhov loj me me ntawm cov ntawv xuab zeb yog qhov sib xws thiab qhov tseeb yog qhov siab, tab sis vim tias lub zog ntawm lub substrate tsis txaus, cov khoom ntxhib ntawm cov xuab zeb tsis tuaj yeem siv, thiab kev ua haujlwm yuav raug txo qis, uas feem ntau haum rau precision. tshuab. xuab zeb daim ntaub substrate lub zog, tuaj yeem siv cov xuab zeb ntxhib, kev ua haujlwm zoo dua, tab sis nws qhov tseeb yog me ntsis qis dua rau cov ntawv xuab zeb.
Thib peb, yuav ua li cas xaiv lawv tus kheej cov ntawv xuab zeb lossis cov ntaub xuab zeb
1. Yuav xaiv cov ntawv xuab zeb li cas
Thaum xaiv cov ntawv xuab zeb, qhov loj me me thiab cov khoom siv abrasive ntawm cov ntawv xuab zeb yuav tsum tau txiav txim siab ua ntej. Qhov loj me me yuav tsum raug xaiv raws li qhov hardness thiab roughness ntawm cov khoom ua tiav, thiab yuav tsum tau hloov kho raws li qhov sib txawv ntawm cov txheej txheem yuav tsum tau ua. Feem ntau siv rau cov rooj tog zaum rooj sib tsoo, acrylic, PU khoom sib tsoo sandpaper granularity yog finer, particle loj xaiv ntawm 200-600, rau hlau sib tsoo yuav xaiv cov grit ntawm 80-120 sandpaper.
2. Yuav xaiv cov ntaub emery li cas
Thaum xaiv cov ntaub xuab zeb, txoj kev weaving thiab nruj ntawm daim ntaub yuav tsum raug xaiv raws li cov duab thiab qhov chaw ntawm cov khoom ua haujlwm. Rau cov txheej txheem saum npoo, koj tuaj yeem xaiv cov ntaub ntub dej fiber ntau emery, cov nyhuv kho tau zoo dua.
Hauv luv luv, xaiv cov ntawv xuab zeb thiab cov ntaub xuab zeb yuav tsum hloov pauv raws li lawv cov kev xav tau tiag tiag, kev xaiv cov abrasive tsim nyog tuaj yeem txhim kho kev sib tsoo, thiab tuaj yeem tau txais txiaj ntsig zoo dua.
