Peb txheej ntawm corrugated board ntau lawm kab hauv kev tsim khoom feem ntau yuav tshwm sim qee qhov tshwm sim uas cuam tshuam rau sab nraub qaum ntawm cov khoom thiab cov khoom zoo, cov tub lag luam xav tau cov ntawv corrugated siab heev hauv lub neej, yog li koj yuav tsum paub txog cov teeb meem hauv kev tsim khoom. corrugated board thiab cov tshuaj, cia ChuangLian packing me me ua rau koj cov lus qhia ntxaws:
Paperboard cuav adhesion teeb meem: qhov tshwm sim no yog hais txog thaum daim ntawv tawm ntawm lub tshuab, ntawm daim ntawv saum npoo thiab daim ntawv yuav tam sim ntawd tawg ntawm qhov xwm txheej.
Cov laj thawj tseem ceeb yog raws li nram no:
(1) siv cov nplaum uas tsis muaj viscosity, lossis cov nplaum tau tas sij hawm;
(2) Lub tshuab ceev ntawm cov kab ntau lawm yog ceev heev;
(3) lub siab cov menyuam ntawm lub tshuab corrugated muaj qhov xwm txheej tsis sib xws los yog hnav;
(4) qhov sib txawv ntawm cov cots ntawm lub tshuab gluing composite loj heev;
(5) cov dej noo ntawm corrugated ntawv nws tus kheej yog siab dhau.
Txoj kev daws teeb meem
(1) txhim kho kev sib raug zoo ntawm cov nplaum, cov ntaub ntawv tseem ceeb qhia tau hais tias cov viscosity ntawm cov nplaum feem ntau nyob rau lub caij ntuj no 60S-90s, lub caij ntuj sov viscosity nyob rau hauv 90S-120s, viscosity ntawm xya-txheej corrugated lub thawv tshaj li peb-txheej thawv yog hais txog 305 qeeb;
(2) lub zog siab yog khaws cia ntawm 1.0Mpa thiab 1.2Mpa, qhov kub ntawm cov yob thiab qhov kub ntawm lub tog raj kheej kom qhuav yog li 160 ℃;
(3) Thaum cov khoom siv hauv tsev corrugated yob ncav cuag 3-3.5 lab meters ntev, nws yuav tsum tau hloov.
RUB board tshwm sim teeb meem: yog hais txog lub corrugated board ua tom qab tsis muaj nto ntawm ib txheej ntawm daim ntawv diffraction nyob rau hauv lub radian ntawm lub ncov corrugated uas tsim concave phenomenon, lub nto zoo li zoo li lub rooj tsavxwm hauv tsev, yog li nws yog hu ua phenomenon ntawm rub lub rooj tsavxwm.
Lub hauv paus ua rau cov tsos ntawm corrugated board washboard yog vim tsis tsim nyog cov nplaum, uas yog tshwj xeeb tshaj yog teeb meem rau cov uas tsis muaj hnyav lub thawv board.
Kev daws rau qhov tshwm sim ntawm lub tshuab ntxhua khaub ncaws yog: kho tus nqi ntawm cov ntawv saum npoo thiab ntau dua ntawm cov duab los qhia es tsis txhob ntawm daim ntawv, qhov no yog tshem tawm thiab txo qhov tshwm sim ntawm lub tshuab ntxhua khaub ncaws 朂 ncaj qha txoj kev zoo (tab sis yuav ua rau tus nqi nce ntxiv); Cov nplaum nplaum zoo tuaj yeem txo cov kua nplaum ntawm lub ncov corrugated; Tswj cov cua kub cua kub ntawm daim ntawv saum npoo ntawm lub preheater, vim tias cov duab los qhia qhuav dhau lawm yuav ua rau cov kua nplaum ntau ntxiv, ua rau muaj qhov tshwm sim ntawm lub tshuab ntxhua khaub ncaws.
