Yuav ua li cas thiaj ua rau tus kheej-nplaum daim ntawv ntau lawm hla lub caij ntuj no Smoothly?

Feem ntau ntawm cov nplaum nyob rau hauv cov kua nplaum txheej ntawmself-adhesive daim ntawv loyog cov organic polymers, uas muaj kev vam khom siab ntawm qhov kub thiab txias. Hauv lwm lo lus, lawv cov khoom siv kho tshuab thiab viscoelasticity yuav cuam tshuam rau qee yam raws li qhov kub ntawm qhov chaw sab nraud hloov pauv. Raws li qhov xwm txheej, tus kheej-nplaum daim ntawv lo cov khoom lag luam yuav xaiv los teeb tsa cov nplaum nrog qhov sib txawv pib viscosity thiab viscosity tsis tu ncua raws li daim ntawv thov tiag tiag ntawm qhov ntsuas kub thiab qhov kub ntawm cov khoom cia ib puag ncig kom hloov mus rau qhov sib txawv siv ib puag ncig thiab ntxiv rau cov neeg siv khoom txaus siab. . cov khoom xav tau.

Ambient kub kuj muaj txiaj ntsig zoo rau kev luam ntawv. Tshwj xeeb tshaj yog nyob rau lub caij ntuj no, nyob rau hauv ib qho chaw uas tsis muaj cua sov thiab cua txias, sab nraud kub yog tsawg, uas ua rau tsis tshua muaj kub nyob rau hauv machinery, khoom, inks thiab luam ntawv cov ntaub ntawv. Noj offset luam ntawv ua piv txwv, lub hauv paus ntsiab lus luam ntawv yog ua kom tiav tus lej hloov pauv los ntawm qhov sib npaug ntawm cov dej thiab tus cwj mem, uas yog, lub tshuab luam ntawv phaj lub tog raj kheej ua ntej kev sib cuag nrog cov dej rau cov menyuam, yog li ntawd cov tsis-graphic hydrophilic feem ntawm cov ntawv luam ntawv phaj. yog thawj zaug watered, thiab ces hu rau tus number case roller, kom cov duab kos yog inked, thiab tom qab ntawd tus number case ntawm daim duab ntawm lub phaj luam ntawv yog thawj zaug xa mus rau daim pam, thiab daim pam cov menyuam hloov cov duab number case rau cov khoom luam ntawv. nyob rau hauv qhov kev txiav txim ntawm lub siab roller. Yog hais tias qhov kub ntawm cov khoom siv lub tshuab yog tsawg, nws yuav ua rau muaj kev cuam tshuam loj rau kev hloov pauv. Nyob rau tib lub sijhawm, tus number case kub yog qhov tsawg, uas yuav ua rau muaj viscosity siab thiab fluidity tsawg ntawm tus number case, yog li tus number case tsis tuaj yeem ntws zoo ntawm tus number case rollers, ua rau tsis zoo ntawm cov number case hloov. , unevenness, ua rau cov xim tsis sib xws ntawm cov ntawv luam tawm, uas ua rau muaj kev cuam tshuam cov duab ntawm cov khoom luam ntawv thiab txo cov nqi luam tawm.

Ua ntej tshaj plaws, peb yuav tsum nkag siab tag nrho cov khoom uas tau tshaj tawm. Paub seb cov khoom ntawm daim nplaum yog ntawv, yas, hlau, lossis iav, thiab lwm yam; paub seb qhov saum npoo ntawm daim nplaum yog tiaj tus lossis nkhaus; paub seb qhov chaw nyob qhov twg cov ntawv nplaum muab tso rau qhov kub siab lossis qis, txawm tias yuav muaj lub hnub ntev ntev lossis los nag Drenching, thiab lwm yam ... Cov yam ntxwv no yuav tsis tsuas yog cuam tshuam rau kev xaiv ntawm tus kheej-nplaum daim ntawv lo cov ntaub ntawv, tab sis kuj cuam ​​tshuam qhov sib txuam ntawm cov nplaum. Piv txwv li, tej yam khoom noj, dej haus los yog kws tshuaj tau sau thiab sau npe ntawm qhov kub thiab txias. Feem ntau, cov nplaum yuav harden ntawm qhov kub thiab txias thiab txo cov viscosity. Txhawm rau kom tsis txhob yaim thiab poob cov cim vim qhov tsis zoo ntawm cov nplaum nplaum tom qab pasting, nws yog ib qho tsim nyog yuav tsum siv daim ntawv nplaum rau tus kheej uas ua tau raws li qhov xav tau ntawm qhov ntsuas kub qis thiab muaj cov viscosity siab pib. Khoom siv.

Qhov thib ob, ua ntej luam ntawv, nws yog ib qho tsim nyog yuav tsum tau thauj thiab khaws cov ntaub ntawv tus kheej nplaum rau hauv lub tshuab luam ntawv ntau lawm 24 teev ua ntej, kom qhov kub thiab av noo ntawm cov ntaub ntawv nplaum rau tus kheej thiab lub tshuab luam ntawv tuaj yeem ncav cuag qhov sib npaug, thiab Qhov kub ntawm lub tshuab luam ntawv tuaj yeem khaws cia ntawm 18 degree txog 25 degree. Cov av noo tuaj yeem khaws cia ntawm 50 feem pua ​​​​rau 65 feem pua..

Ib qho yog muab tso rau ntawm lub rhaub dej ntawm ib sab ntawm cov khoom siv, uas tuaj yeem muab tso ua ntej kev txiav tuag thiab ntawm qhov chaw pov tseg kom sov rau saum npoo ntawm cov khoom; lwm qhov yog ntxiv cov phaj cua sov lossis cov cua sov rau cov khoom siv tuag kom nce qhov kub ntawm cov khoom; Cov khoom lag luam ib nrab tau muab tso rau hauv qhov chaw sov so rau ib lub sijhawm, kom qhov kub thiab txias ntawm daim ntawv lo rau nws tus kheej nce siab kom txo tau qhov tshwm sim ntawm daim ntawv lo poob; Qhov thib plaub yog ua kom tag nrho cov txheej txheem dhau los, xws li cov khoom uas yuav tsum tau coated, ua kom sov lub pre-coated zaj duab xis thiab Adhesive daim ntawv lo nto daim ntawv lo, muab qhov tseem ceeb rau tuag-txiav semi-tiav khoom tom qab lamination, ua tag nrho. siv qhov seem kub ntawm qhov chaw ntawm cov ntaub ntawv semi-tiav los txhim kho qhov teeb meem ntawm daim ntawv lo poob thiab pov tseg pov tseg tshwm sim los ntawm qhov kub thiab txias ntawm kev txiav tuag.
