Yuav Ua Li Cas Xaiv Sandpaper BACTIC ntawv

Cov khoom siv hauv paus, cov abrasive thiab binder yog peb qhov tseem ceeb ntawm coated abrasives. Ntawm lawv, lub hauv paus ntawv yog cov siv ntau tshaj plaws thiab cov khoom siv ntau tshaj plaws. Cov ntawv hauv paus tsuas yog siv los tsim dej- Rawing sandpapers, qhov zoo} Raws li cov khoom ua haujlwm ncaj qha cuam tshuam cov khoom lag luam zoo. Vim muaj qhov sib txawv tseem ceeb hauv kev tsim khoom thiab cov txheej txheem ntawm ntau yam khoom lag luam tsim nyog muaj txiaj ntsig zoo hauv cov khoom lag luam ruaj khov.

 

I. Cov xwm txheej tam sim no ntawm cov ntawv nyoos tsim kev lag luam

Raws li kev muaj tshwj xeeb muaj, cov ntawv sau muaj abrasive ntawv tau ntev tau txwv los ntawm kev ua lag luam tsawg dua los ntawm nws daim ntawv thov tshwj xeeb. Txawm li cas los xij, nrog kev hloov pauv nrawm ntawm Tuam Tshoj txoj kev lag luam tsim kev lag luam rau high-}}} Pressor tau qhia txog kev loj hlob tseem ceeb hauv xyoo tas los. Txawm li cas los xij, vim muaj kev cuam tshuam zoo thiab tus nqi tswj cov khoom lag luam uas yuav tsum tau muaj ntawm cov khoom, cov nyiaj tau los ntawm kev lag luam tseem tsawg. Tam sim no, cov kev lag luam muaj kev lag luam hauv tsev tau tsim cov txheej txheem xa khoom raw ua tau raws li cov ntaub ntawv muaj abrasive ua lag luam. Tshwj xeeb nyob rau hauv cov liaj teb hnyav - futtic latrasged siv, nrog qee qhov kev ua yeeb yam mus cuag cov qauv rau kev hloov chaw. Txawm li cas los xij, nyob rau hauv kev tsim cov siab - kev lag luam cov ntawv sau ua ke thiab kev tsim khoom loj}}} tab kaum kev ua hauv lub siab ntawm high-}} cov khoom. Txhawm rau los ntawm cov thev naus laus zis thev naus laus zis, kev txhim kho kev sib koom tes hauv kev lag luam ntawm cov khoom siv tsis zoo los ntawm cov cuab yeej tseem ceeb thiab tsim kho cov txheej txheem tseem ceeb.

 

 

Ii. Kev tsis nkag siab hauv kev xaiv cov khoom siv

1. Qhov sib txawv hauv daim ntawv rau kev ntxhib thiab zoo khau
Ntxhoo - grit sandpapers yuav tsum tau ntau dua cov ntawv hnyav, thaum nplua- grit sandpapers xav tau cov ntawv hnyav qis dua. Nplua {{3} grit sandpapers, vim lawv cov nplaum abrasive thiab cov nplaum tsis tshua muaj rau cov ntawv smoothness, tshwj xeeb tshaj yog zam cov ntawv fuzz. Qhov yuav tsum tau ua rau ntxhib - grit sandpapers yog cov xoob xoob.
2. Cov hauv paus ntsiab lus rau kev xaiv cov nplaum
Cov nplaum yuav tsum tau xaiv raws li lub hauv paus ntawv: Epoxy Resin rau qib beet beet rau qib kev sib tsoo rau cov ntawv luam yeeb (siv rau cov ntaub qhwv zoo li qub Qee cov lag luam siv alkyd lossis urea - daim ntawv sau cia hauv qib thiab yas yuav tsum tau them rau cov txheej txheem sib xws; Txwv tsis pub, nws yuav ua rau tawg thiab kev txiav txim siab.
3. Nrhiav rau pem hauv ntej thiab rov qab ntawm daim ntawv
Cov ntawv hauv paus muaj sab pem hauv ntej thiab sab nraub qaum: ib sab hauv kev sib cuag nrog lub papermaking hlau yog sab nraub qaum, thiab lwm sab yog sab xub ntiag (smoother). Sab pem hauv ntej thiab nram qab yuav raug txheeb xyuas los ntawm folding kom pom qhov sib txawv hauv cov qauv qauv lossis los ntawm kev ziab khaub ncaws (curling inward qhia sab nraum qab).
4. Kev tswj hwm ntawm tshav kub tiv thaiv kev ua tau zoo
Cov dej dog dig - Cov khoom siv xau tuaj yeem tiv thaiv kub ntawm 70, thaum qib ib daim ntawv kho ntawm 70- Qeb ib daim ntawv kho nrog hloov kho sizing tuaj yeem tiv taus kub txog 120 degree. Kev tswj kom kub nruj yog qhov tsim nyog thaum ntau lawm thaum tsim khoom los tiv thaiv cov khoom siv hluav taws xob.
5. Nkag siab rau kev siv cov tshuaj ntxiv
Cov tshuaj sib ntxiv ntawm cov tshuaj ntau dhau yuav nce cov ntawv tensile muaj zog tab sis tabkaum resin nkag. Kev ntsuam xyuas kev kawm txog qhov ntsuas tau xws li lub hauv paus hnyav, thiab kev nqus dej, yog qhov ua kom muaj txiaj ntsig zoo rau kev ua lub zog.

 

 

III. Yuav tsum muaj rau Sandpaper Base Khoom Siv

 

1. Cov tsos zoo ntawm lub hauv paus ntawv yuav tsum ua kom tau raws li cov ntawv hauv qab no: tshwj xeeb tshaj yog rau cov teeb meem xim, tshwj xeeb yog kom tsis txhob muaj teeb meem hauv cov lag luam luam ntawv; Qhov saum npoo yuav tsum huv tsis muaj wrinkles, lub qhov, lossis lwm yam tsis xws luag, thiab rau daim ntawv xim, cov pob yuav tsum tau zam tag; Daim ntawv saum npoo yuav tsum yog tiaj nrog me ntsis muaj qhov hnyav, thiab cov tuab yuav tsum muaj cov ris tsho sib txawv hauv cov kev taw qhia ntau dua; Lub ntug ntawm cov yob loj yuav tsum yog qhov kev puas tsuaj, cov raj tub tub ntxhais lub raj, thiab qhov hnyav ntawm ib yob yog kev pom zoo kom tswj tau hauv ntau ntawm 300-600kg.
2. Nyob rau hauv cov nqe lus ntawm sab hauv zoo: 100% sulfate softwood pulp yuav tsum siv rau kev tsim khoom, thiab daim ntawv puas yog txwv tsis pub muaj; Cov ntawv ceeb thawj lub hauv paus yuav tsum tau xaiv raws li cov ntawv ntawm cov ntawv, lub teeb yuag, daim ntawv hnyav rau cov ntxhib thiab hnyav} grit Sandpaper; Qhov ceev yuav tsum tau sib npaug kom ob qho tib si muaj zog thiab hloov tau yooj yim; Cov dej nqus dej yuav tsum tau tswj kom tsis txhob muaj dej noo {{}}}} Tus tiv thaiv cov suab paj nruag yuav tsum muaj dej siab tiv thaiv; Kev faib tshuaj fiber ntau yuav tsum tau sib xyaw, thiab kev xav tau kev sib xws, thiab kev xav tau kev cai rau pob tshab ntoo yog qhov siab heev; Txawm hais tias lub hauv paus ntawv rau ultra {{Precision sib tsoo ntawm cov ntawv sib tsoo thiab qis {{{{{{{{{{{{{{{{{{{{{{{{{{{}}}}}}}}}}}}
