Kev sib xyaw thiab teeb meem ntawm cov txheej txheem tsim tawm ntawm daim ntawv coater

Dab tsi yog cov khoom thiab cov teeb meem ntawm cov txheej txheem tsim tawm ntawm daim ntawv coater?
Cov txheej txheem tsim khoom ntawm cov tawv tawv tso tawm cov ntawv feem ntau yog tsim los ntawm kev tso tawm txheej ntawm cov ntawv hauv paus thiab embossing.
Daim ntawv tso tawm muaj cov kev xav tau siab rau cov ntawv hauv paus, uas yog, daim ntawv hauv paus, tsuas yog yuav tsum muaj lub zog siab thiab nruj raws li qhov yuav tsum tau ua rau kub tsis kam, xoob thickness thiab noo noo cov ntsiab lus. Nyob rau hauv cov nqe lus ntawm cov ntawv hauv paus kom muaj nuj nqis, daim ntawv uas muaj ntau tshaj 125g / m2 feem ntau xaiv. Cov txheej txheem nyuaj hauv kev tsim cov ntawv hauv paus los ntawm txheej tshuab yog tswj cov xoob tuab thiab kub tsis kam ntawm cov ntawv hauv paus. Nyob rau hauv nam ntawm xoob thickness, coniferous ntoo pulp thiab hardwood pulp feem ntau yog xaiv los tswj qhov xav tau ntawm tshav kub tsis kam. Thaum tshav kub kub resistant tus neeg sawv cev yog ntxiv rau lub pulp los txhim khu lub tshav kub tsis kam ntawm daim ntawv.
Ntau hom kev tso tawm txheej muaj cov yam ntxwv sib txawv. Piv txwv li, silicone resin txheej muaj kev ua haujlwm zoo heev thiab ua haujlwm kub, chromium complex txheej muaj cov kuab tshuaj tsis zoo, thiab polypropylene txheej muaj gloss siab tab sis tsis zoo cua sov.
Feem ntau, cov txheej txheej tso tawm tuaj yeem muab faib ua ob hom, uas yog, silicon tso txheej txheej thiab tsis-silicon tso txheej txheej. Silicone tso cov ntaub ntawv muaj xws li silicone resin thiab alkyd resin acrylic resin rau hloov silicone resin. Cov ntaub ntawv tsis muaj silicon muaj xws li chromium complex, methacrylic acid hom lossis fatty acid hom polypropylene resin, polymethylpentene resin tpx thiab lwm yam tshwj xeeb resins, aminoalkyd resin, epoxy resin, thiab lwm yam.
Yuav ua li cas ntxuav lub coater:
Kev ntxuav ntawm txheej txheej cutter taub hau: so nrog cov ntaub qhwv qhuav tom qab cov khoom cua sov. Ntxuav cov menyuam ncej: siv cov ntaub qhwv qhuav qhuav dipped hauv 75 feem pua ​​​​ntawm cawv los so cov hlau stainless cov menyuam ncej. Yog tias muaj cov kua nplaum rau ntawm qhov chaw, siv cov ntaub qhwv qhuav dipped hauv 1620 hnyav / ethyl acetate hnyav los so; Cov kua nplaum rau ntawm qhov chaw ntawm cov roj hmab rau cov menyuam ncej yuav tsum tsis txhob raug kho nrog cov kuab tshuaj organic kom tsis txhob ua rau cov roj hmab cov menyuam ncej puas. Nws yuav tsum tau muab tshem tawm nrog muaj zog adhesive curing nplaum. Sab nraud ntawm cov khoom siv; Txoj kev ntxuav: so nrog cov ntaub qhwv qhuav qhuav dipped hauv 75 feem pua ​​​​ntawm cawv. Batch hloov tu: tu lub thawv kua nplaum thiab hose ntawm cov kua nplaum kub yaj nplaum (tseem siv tau los hloov cov qauv kua nplaum thiab txheej txheej): tom qab tshem cov kua nplaum qub, ntxiv 2 ~ 3Kg ntawm cov kua nplaum tshiab, kub kom txog thaum nws yaj tag. , thiab ces tag nrho nws, thiab ces ntxiv cov kua nplaum tshiab. Tom qab nws tau yaj tag, yam tsawg kawg 1Kg ntawm cov kua nplaum tshiab yuav raug tso tawm kom pib tsim khoom.
Kev ntxuav ntawm txheej txheej cutter lub taub hau (tseem siv tau rau kev hloov cov qauv kua nplaum thiab txheej txheej): so nrog cov ntaub qhwv qhuav tom qab cov khoom cua sov. Roller ncej ntawm txheej txheej txoj hauj lwm; So cov plua plav saum npoo nrog cov ntaub qhwv qhuav qhuav; Yog tias pom cov kua nplaum rau ntawm qhov chaw, nws yuav tsum tsis txhob raug kho nrog cov kuab tshuaj organic kom tsis txhob ua rau cov roj hmab cov menyuam ua haujlwm. Nws yuav tsum tau muab tshem tawm nrog muaj zog adhesive curing nplaum.
Kev tu cov cuab yeej corona: Tom qab paub meej tias lub hwj chim raug tua, so nws nrog cov ntaub qhwv huv huv qhuav dipped hauv 75 feem pua ​​​​ntawm cawv. Kev tu lub sijhawm tsis tu ncua ntawm lub tshuab kub yaj nplaum nplaum txheej tshuab: thaum txheej txheej txheej thiab qib ntawm cov kua nplaum hloov, lub taub hau ntawm lub tshuab kub yaj nplaum nplaum yuav tsum tau ntxuav. Thaum lub sij hawm ntxuav, lub taub hau txheej yuav tsum tau muab tshem tawm ua ntej cov kua nplaum yog solidified, thiab lub taub hau txheej yuav tsum tau wiped huv si nrog qhuav gauze dipped nyob rau hauv 1620 hnyav. Thaum lub sij hawm tsim cov txheej txheem, cov ntaub qhwv huv huv yuav tsum tau siv los so cov kua nplaum uas nchuav thaum cov khoom siv nres thiab pib. Ntxuav cov ntxaij lim dej ntawm cov roj hmab lub thawv ntawm cov nplaum nplaum kub yaj hauv ib nrab ib hlis. Ntxuav cov ntxaij lim dej ntawm lub taub hau txheej ntawm cov kub yaj nplaum txheej tshuab. Yog tias qhov kev tsim khoom raug tso tseg ntau tshaj li ib hlis, tag nrho cov khoom siv txheej txheej yuav tsum tau muab ntxuav ib zaug raws li cov ntsiab lus saum toj no thiab cov kev xav tau ntawm kev tu txhua hnub, ua ntej thiab tom qab kev hloov pauv, ib nrab lub hlis thiab lub voj voog tsis tas ua ntej muab tso rau hauv kev siv; Rau lub thawv kua nplaum ntawm cov nplaum nplaum kub, tom qab tshem tawm cov kua nplaum qub, kwv yees li 30Kg dawb pob zeb hauv av yuav tsum tau ntxiv kom yaj cov kua nplaum seem, thiab tom qab tshem tawm, txog 30Kg dawb ntxhia roj yuav tsum tau ntxiv kom yaj dua, thiab tom qab ntawd yuav tsum tau muab ntxiv rau cov kua nplaum. siv tom qab ua tiav tas.
