Yuav ua li cas kho tus number case flexo printing txheej txheem nrog txawv thawv ntawv
Cov hom ntawm cov ntawv hauv paus siv rau corrugated lub thawv ntawv saum npoo muaj xws li: thawv board ntawv, liner ntawv, kraft cardboard, tshuaj yej board ntawv, ntawv dawb board thiab ib sab coated dawb board ntawv. Vim qhov sib txawv ntawm cov ntaub ntawv papermaking thiab cov txheej txheem papermaking ntawm txhua hom ntawv hauv paus, cov cim qhia lub cev thiab tshuaj lom neeg, cov khoom nto thiab kev luam tawm ntawm cov ntaub ntawv hauv qab no sib txawv heev. Cov hauv qab no yuav tham txog cov teeb meem tshwm sim los ntawm cov khoom lag luam uas tau hais los saum toj no rau corrugated cardboard number case printing pib txheej txheem.
1. Cov teeb meem tshwm sim los ntawm cov ntawv qis qis chocolate thawv
Thaum cov ntawv qis-gram hauv qab siv los ua cov ntawv saum npoo ntawm corrugated cardboard, cov cim corrugated yuav tshwm rau saum npoo ntawm daim ntawv corrugated. Nws yog ib qho yooj yim los ua flute thiab cov ntsiab lus duab yuav tsum tsis tuaj yeem luam tawm ntawm qhov qis concave ntawm lub tshuab raj. Nyob rau hauv kev pom ntawm qhov tsis sib xws ntawm daim duab los qhia corrugated los ntawm lub raj nplaim, lub phaj hloov tau yooj yim nrog kev ua haujlwm zoo dua yuav tsum tau siv los ua cov ntawv luam ntawv kom kov yeej kev luam ntawv tsis zoo. Clear thiab nthuav tawm flaws. Tshwj xeeb tshaj yog rau A-type corrugated cardboard uas ua los ntawm cov ntawv qis-grammage, lub tiaj tus compressive lub zog ntawm corrugated cardboard yuav zoo heev tom qab luam tawm los ntawm lub tshuab luam ntawv. Muaj kev puas tsuaj loj.hniav nyiaj hniav kublub thawv
Yog hais tias qhov saum npoo ntawm corrugated cardboard txawv ntau dhau, nws yog ib qho yooj yim los ua warping ntawm corrugated cardboard uas ua los ntawm corrugated cardboard kab. Warped cardboard yuav ua rau overprinting tsis raug thiab tawm-ntawm-gauge printing slots rau luam ntawv, yog li cov warped cardboard yuav tsum flattened ua ntej luam ntawv. Yog tias qhov tsis sib xws corrugated cardboard raug yuam luam tawm, nws yooj yim ua rau muaj qhov tsis sib xws. Nws tseem yuav ua rau lub thickness ntawm corrugated cardboard txo.
2. Cov teeb meem tshwm sim los ntawm qhov sib txawv roughness ntawm cov ntawv hauv paus ntawv-khoom plig- ntim
Thaum luam ntawv rau hauv daim ntawv nrog ntxhib nto thiab xoob qauv, tus number case muaj permeability siab thiab cov luam ntawv number case dries sai, thaum luam ntawv ntawm daim ntawv nrog siab nto smoothness, ntom fiber ntau thiab toughness, tus number case qhuav ceev yog qeeb. Yog li ntawd, ntawm daim ntawv rougher, tus lej ntawm daim ntawv thov yuav tsum tau nce, thiab ntawm daim ntawv du, tus lej ntawm daim ntawv thov yuav tsum raug txo. Cov ntawv luam tawm ntawm cov ntawv tsis loj dries sai, thaum cov ntawv luam tawm ntawm cov ntawv loj dries maj mam, tab sis qhov rov ua dua ntawm cov qauv luam tawm yog qhov zoo. Piv txwv li, tus number case nqus ntawm coated whiteboard ntawv yog qis dua li ntawm cov ntawv thawv ntawv thiab cov ntawv teaboard, thiab cov number case dries maj mam, thiab nws smoothness yog siab dua li ntawm cov ntawv boxboard, liner ntawv, thiab teaboard ntawv. Yog li ntawd, qhov kev daws teeb meem ntawm cov ntawv sau rau ntawm nws Tus nqi kuj yog siab, thiab qhov kev tsim tawm ntawm nws cov qauv zoo dua li cov ntawv liner, daim duab los qhia, thiab daim ntawv tshuaj yej.
3. Cov teeb meem tshwm sim los ntawm qhov sib txawv ntawm cov ntaub ntawv nqus hnub box
Vim qhov sib txawv ntawm cov ntaub ntawv raw khoom thiab cov ntawv hauv paus sizing, calendering, thiab txheej sib txawv, lub zog nqus yog txawv. Piv txwv li, thaum overprinting ntawm ib sab coated dawb board ntawv thiab kraft phaib, lub ziab ceev ntawm tus number case yog qeeb vim qhov tsis zoo nqus. qeeb, yog li qhov concentration ntawm tus number case yav dhau los yuav tsum tau txo, thiab viscosity ntawm tus number case overprint tom ntej yuav tsum tau nce. Sau cov kab, cov cim, thiab cov qauv me me hauv thawj xim, thiab luam tag nrho cov phaj hauv cov xim kawg, uas tuaj yeem txhim kho cov nyhuv ntawm overprinting. Tsis tas li ntawd, luam cov xim tsaus nyob rau hauv pem hauv ntej thiab lub teeb xim nyob rau hauv qab. Nws tuaj yeem npog qhov yuam kev overprint, vim tias cov xim tsaus muaj kev tiv thaiv zoo, uas yog qhov zoo rau cov txheej txheem overprint, thaum lub teeb xim muaj qhov tsis muaj zog, thiab nws tsis yooj yim rau kev soj ntsuam txawm tias muaj qhov tshwm sim khiav tawm hauv kev luam ntawv tom qab. hnub box
Cov xwm txheej sib txawv ntawm cov ntawv hauv qab yuav cuam tshuam rau tus cwj mem nqus. Daim ntawv nrog ib tug me me ntawm sizing absorbs number case ntau, thiab daim ntawv nrog ib tug loj npaum li cas ntawm sizing absorbs tsawg number case. Yog li ntawd, qhov sib txawv ntawm tus number case rollers yuav tsum tau kho raws li qhov loj ntawm daim ntawv, uas yog, qhov sib txawv ntawm tus number case rollers yuav tsum raug txo kom tswj tau cov ntawv luam ntawv. ntawm ink. Nws tuaj yeem pom tau tias thaum daim ntawv hauv paus nkag mus rau hauv lub Hoobkas, qhov kev ua tau zoo ntawm cov ntawv hauv paus yuav tsum raug kuaj, thiab qhov ntsuas qhov nqus ntawm cov ntawv hauv paus yuav tsum tau muab rau lub tshuab luam ntawv slotting thiab tus number case dispenser, yog li ntawd. lawv tuaj yeem faib cov cwj mem thiab kho cov khoom siv. Thiab raws li lub xeev nqus ntawm cov ntaub ntawv sib txawv, kho cov viscosity thiab PH tus nqi ntawm tus number case.
