Daim ntawv, Wikipedia txhais tias nws yog cov khoom siv tsis-woven ua los ntawm cov nroj tsuag fibers uas tuaj yeem muab tais rau ntawm lub siab nyiam thiab siv rau kev sau ntawv.
Keeb kwm ntawm ntawv yog keeb kwm ntawm tib neeg kev vam meej. Los ntawm qhov tshwm sim ntawm daim ntawv nyob rau hauv Western Han Dynasty mus rau Cai Lun txoj kev txhim kho papermaking technology nyob rau hauv Eastern Han Dynasty, thiab tam sim no, ntawv tsis yog ib tug cab kuj rau sau ntawv, tab sis kuj yuav siv tau rau lwm yam hom phiaj xws li luam ntawv, ntim, kev lag luam. , thiab lub neej txhua hnub.
01 Scope ntawm daim ntawv thov
Cov khoom siv muaj xws li: daim ntawv kab lis kev cai, cov ntawv muaj thiab kev ua liaj ua teb, cov ntawv ntim khoom thiab cov ntawv hauv tsev.
Kuv lub teb chaws cov ntawv tuaj txawv teb chaws feem ntau suav nrog cov ntawv kab lis kev cai (cov ntawv xov xwm, ntawv coated, ntawv offset, ntawv sau) thiab cov ntawv ntim (kraft ntawv, ntawv dawb, ntawv corrugated, ntawv dawb, cellophane, thiab lwm yam).
02 Kev soj ntsuam cov ntsiab lus tseem ceeb
Qhov tshwm sim
Ua kom pom tseeb: tshwm sim
Smooth, huv si, thiab lwm yam.
Qhov zoo ntawm daim ntawv yog qhov tseem ceeb hauv kev txiav txim siab ntawm daim ntawv zoo. Nws tsis tsuas yog cuam tshuam rau kev zoo nkauj ntawm daim ntawv, tab sis qee qhov tsos mob yuav cuam tshuam rau kev siv ntawm daim ntawv.
Kev soj ntsuam zoo ntawm daim ntawv feem ntau yog siv lub teeb tshuaj xyuas, kev tshuaj xyuas lub teeb tiaj tus, kev tshuaj xyuas squint thiab tshuaj xyuas tes. Daim ntawv saum npoo yuav tsum tau du thiab huv si, thiab tsis muaj folds, wrinkles, puas, nyuaj blocks, lub teeb kis me ntsis, ntses nplai me ntsis, xim sib txawv, ntau yam me ntsis thiab pom tseeb muaj cov cim tau tso cai.
Nco tseg: Kev tshuaj xyuas zoo ntawm cov ntawv xa tawm yog ua raws li ZBY32033-90.
Lub cev muaj zog
Ua kom pom tseeb: los ntawm kev faib tawm
Cov ntawv sib txawv muaj qhov sib txawv
Cov ntawv luam tawm: Cov ntawv xov xwm yuav tsum muaj cov ntawv mos thiab compressible, thiab daim ntawv saum npoo yuav tsum tau nqus tau zoo heev. Txhawm rau kom ntseeg tau tias tus number case luam ntawv tuaj yeem qhuav sai thaum lub sijhawm luam ntawv. Daim ntawv yuav tsum tau ua kom du ntawm ob sab, zoo ib yam nyob rau hauv thickness, nrog zoo opacity, tsis muaj lint los yog smear thaum lub sij hawm luam ntawv, meej qauv, thiab tsis muaj perspective defects. Daim ntawv yob yuav tsum nruj nruj ntawm ob qho kawg ntawm yob, ob peb lub pob qij txha, thiab lub zog tensile zoo kom haum rau kev luam ntawv ntawm cov tshuab luam ntawv siab ceev.
Cov kev cai zoo rau cov ntawv coated: smoothness. Daim ntawv saum npoo yuav tsum du heev kom nws tuaj yeem ua tiav kev sib cuag nrog lub ntsej muag ntawm lub vijtsam tooj liab phaj thaum luam ntawv, yog li tau txais cov qauv zoo nkauj thiab meej meej nrog cov duab tiag tiag thiab ua kom pom tseeb.
Daim ntawv dawb: Daim ntawv dawb feem ntau yuav tsum muaj kev ntxhib los mos, du nto, tuab tuab, tsis muaj lint-dawb daim ntawv nto, zoo absorbency thiab me me expansion tus nqi kom haum raws li cov kev cai ntawm ntau xim overprinting. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm lub thawv tsim, daim ntawv whiteboard yuav tsum muaj cov yam ntxwv ntawm qhov siab tawv thiab muaj zog folding tsis kam.
Kraft daim ntawv: Kraft daim ntawv yog ib daim duab los qhia tshwj xeeb uas siv rau cov khoom ntim, yog li qhov kev ntxhib los mos ntawm daim ntawv yuav tsum tawv, muaj zog tawg, lub nplhaib crush lub zog thiab lub zog tearing. Tsis tas li ntawd, nws yuav tsum muaj kev tiv thaiv dej siab kom thaum lub sij hawm thauj dej hiav txwv los yog cia txias, lub zog yuav tsis txo qis vim qhov nqus dej ntau, ua rau lub thawv puas tsuaj. Cov ntawv kraft uas yuav tsum tau siv rau kev luam ntawv yuav tsum muaj qee yam smoothness.
Corrugated puag daim ntawv: Corrugated puag ntawv yuav tsum muaj fiber ntau zoo zog, du daim ntawv nto, thiab siab nruj thiab nruj. Ib qho degree ntawm elasticity yog yuav tsum tau los tuav lub shock-proof thiab siab-resistant peev xwm ntawm cartons ua. Yog li ntawd, bursting lub zog thiab lub nplhaib crush lub zog (los yog tiaj tus crush lub zog) yog lub ntsiab lus qhia txog lub zog ntawm corrugated puag ntawv. Tsis tas li ntawd, qhov ntsuas dej noo yuav tsum tau tswj hwm. Yog tias cov dej noo tsawg dhau, daim ntawv yuav nkig thiab tuaj yeem tawg thaum lub sij hawm ua corrugate. Cov dej noo ntau dhau yuav ua rau muaj teeb meem hauv kev ua haujlwm. Feem ntau, cov dej noo yuav tsum nyob ib ncig ntawm 10%.
Cellophane: Cellophane yog pob tshab hauv cov xim, ci hauv qhov chaw, sib xws hauv tuab, mos thiab stretchable. Nws yuav o thiab ua softer tom qab muab tso rau hauv dej, thiab nws yuav poob qis tom qab ziab. Nws muaj qhov nqus dej siab thiab ua rau cov tawv nqaij thiab txawm tias nplaum thaum raug dej. Tsis tas li ntawd, vim yog kev sib xyaw ua ke ntawm cellulose microcrystals nyob rau hauv cov kev taw qhia longitudinal, longitudinal lub zog ntawm daim ntawv yog loj thiab transverse kev taw qhia me me. Yog tias muaj cov kab nrib pleb, nws yuav tawg nyob rau hauv qhov tsawg kawg nkaus quab yuam. Cellophane yog airtight, oil-tight thiab water-tight.
Offset printing ntawv: Offset ntawv yog siv rau ntau xim overprinting. Ntxiv nrog rau qhov zoo dawb thiab tsis muaj plua plav, nws tseem muaj qhov yuav tsum tau ua rau daim ntawv nruj, lub zog tensile, thiab folding kuj. Thaum lub sij hawm luam ntawv, qhov saum npoo ntawm daim ntawv tsis tso lint, hmoov, los yog luam tawm. Cov kev xav tau yog tib yam li cov ntawv coated.
