Nyob rau hauv cov txheej txheem gluing ntawm cov thawv ntim khoom, kev xaiv thiab siv cov kua nplaum kom raug cuam tshuam rau kev ua haujlwm ntawm kev ua haujlwm, kev sib khi lub zog, thiab cov khoom tsim nyog ntawm Semi Automatic Folder Gluer Tshuab. Mastering scientific kua nplaum xaiv thiab siv cov tswv yim yog qhov tseem ceeb rau kev txhim kho gluing stability.
Kev xaiv cov kua nplaum yuav tsum ua kom raug raws li cov yam ntxwv ntawm daim duab los qhia thiab daim ntawv thov scenario. Rau kev sib koom ua ke ntawm cov thawv ntawv corrugated, dej-raws li cov kua nplaum dawb thiab ceev- dej qhuav-raws li cov kua nplaum yog cov kev xaiv tseem ceeb: lub qub muaj nruab nrab pib tack thiab siab bonding lub zog, haum rau cov pa sib txuas ntawm peb- txheej thiab tsib- txheej corrugated phooj ywg, thiab thiab tsis muaj ntxhiab tsw, ua tau raws li qhov xav tau ntawm ib puag ncig ntawm kev ntim khoom noj thiab lwm yam xwm txheej; tom kawg muaj kev kho ceev ceev, yoog raws qhov kev xav tau ceev ceev ntawm cov khoom loj, thiab txo lub sijhawm tos rau cov ntawv xovxwm. Nws yog ib qho tsim nyog yuav tsum tsis txhob siv cov kua nplaum tsis zoo nrog cov viscosity ntau dhau lossis cov ntsiab lus tsis txaus. Tsawg- cov kua nplaum nplaum yog qhov ua rau cov kua nplaum tsis zoo thiab tsis muaj zog, thaum siab - cov kua nplaum nplaum ua rau muaj kev nyuaj ntawm gluing, ua rau tsis sib xws gluing thiab tshuab jamming.
Kev siv cov nplaum nplaum yuav tsum "tswj viscosity, ntau npaum li cas, thiab ib puag ncig." Adhesive viscosity yuav tsum tau dynamically hloov raws li cov av noo thiab kub ntawm cardboard. Raws li ib txwm muaj, nws yuav tsum tau tswj ntawm 15,000-25,000 mPa·s. Nyob rau hauv high humidity, lub viscosity tuaj yeem tsim nyog kom tsis txhob muaj cov nplaum nplaum ntau dhau. Tus nqi ntawm cov nplaum siv yuav tsum tau tswj nruj me ntsis. Los ntawm kev kho qhov sib txawv ntawm lub applicator rollers nyob rau hauv Semi Automatic Folder Glue Tshuab, xyuas kom meej tias cov nplaum sib npaug npog qhov sib txuas ntawm qhov chaw, tsis muaj qhov chaw ploj lossis dhau mus. Nyob rau tib lub sijhawm, cov nplaum nplaum yuav tsum tau npaj thiab siv tam sim ntawd kom tsis txhob muaj kev sib cais thiab sedimentation vim kev cia ntev ntev. Nws yuav tsum tau nplawm kom huv si ua ntej siv. Yog tias tsim nyog, ib qho tshwj xeeb nyias tuaj yeem ntxiv los kho cov viscosity. Ntxiv dej arbitrarily yog nruj me ntsis txwv tsis pub, raws li nws tej zaum yuav ua rau puas cov nplaum Cheebtsam.
Environmental yam muaj feem cuam tshuam rau cov nplaum nplaum. Qhov kub ntawm lub rooj cob qhia yuav tsum tswj ntawm 18-28 degree, thiab cov av noo tswj ntawm 45% -65%. Tsis tshua muaj kub yuav ua rau qeeb ntawm cov nplaum curing ceev thiab ntev lub sij hawm nias; high humidity yuav txo cov nplaum kom qhuav efficiency thiab ua rau muaj kev pheej hmoo ntawm delamination. Tsis tas li ntawd, cov ntawv nplaum nplaum yuav tsum tau nias thiab zoo li tus. Los ntawm kev kho lub siab ntawm cov nias rau ntawm Semi Automatic Folder Gluer Tshuab, nws tau ua kom ntseeg tau tias cov nplaum nplaum yog nruj nruj. Lub sijhawm nias tau pom zoo kom tsis pub tsawg tshaj 3 feeb kom tsis txhob muaj kev sib raug zoo lossis delamination ntawm cov pob qij txha vim kev tuav ua ntej.
