Daim ntawv, Wikipedia txhais tau tias nws yog cov ntaub tsis-woven ua los ntawm cov nroj tsuag fibers uas tuaj yeem muab tais rau ntawm lub siab nyiam 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 sab hnub poob Han Dynasty, mus rau kev txhim kho ntawm papermaking los ntawm Cai Lun 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.
Hauv qhov teeb meem no, cia peb saib cov kev soj ntsuam dav dav / kev soj ntsuam cov ntsiab lus tseem ceeb thiab cov kev txiav txim siab tsis zoo ntawm cov khoom siv ntawv.
Scope ntawm daim ntawv thov
Cov khoom lag luam uas cov lus qhia no siv suav nrog: daim ntawv kab lis kev cai, ntawv kev lag luam thiab kev ua liaj ua teb, ntawv ntim thiab ntawv hauv tsev. Kuv lub teb chaws cov ntawv tuaj txawv teb chaws yog cov ntawv xov xwm (cov ntawv xov xwm, cov ntawv coated, ntawv offset, ntawv sau) thiab cov ntawv ntim khoom (kraft cardboard, dawb cardboard, corrugated base paper, white cardboard, cellophane, thiab lwm yam).
02 Kev soj ntsuam tsom
| Qhov tshwm sim
Cov tsos ntawm daim ntawv yog ib qho tseem ceeb hauv kev txiav txim siab zoo ntawm daim ntawv. Nws tsis tsuas yog cuam tshuam rau cov tsos ntawm daim ntawv, tab sis qee qhov tsos mob kuj cuam tshuam rau kev siv ntawm daim ntawv.
General Inspection Guide for Paper Products
Kev soj ntsuam zoo ntawm daim ntawv feem ntau yog siv cov txheej txheem ntawm kev tshuaj xyuas lub ntsej muag, kev tshuaj xyuas tiaj tus, kev tshuaj xyuas squint thiab kev tshuaj xyuas tes. Qhov saum npoo ntawm daim ntawv yuav tsum tiaj tus thiab huv si, thiab tsis muaj folds, wrinkles, puas, nyuaj blocks, lub teeb kis me ntsis, ntses nplai me ntsis, chromatic aberration, ntau yam me ntsis thiab pom tseeb ntaub plaub raug tso cai. Nco tseg: Kev tshuaj xyuas zoo ntawm cov ntawv xa tawm yog ua raws li cov cai ntawm ZBY32033-90.

Cov ntsiab lus tseem ceeb: Cov ntawv xav tau sib txawv txawv raws li kev faib tawm
Cov ntawv luam tawm: Cov ntawv xov xwm yuav tsum tau ntawv kom mos thiab compressible, thiab daim ntawv saum npoo yuav tsum muaj ntau dua absorbency. Txhawm rau kom ntseeg tau tias tus number case luam ntawv tuaj yeem qhuav sai thaum lub sijhawm luam ntawv. Nws yuav tsum tau hais tias ob sab ntawm daim ntawv yog du, lub thickness yog zoo ib yam, lub opacity yog zoo, lub luam ntawv yog dawb lint, tsis paste rau lub phaj, tus qauv yog meej, thiab tsis muaj kev xav tsis zoo. Rau cov ntawv yob, ob qhov kawg ntawm cov yob yuav tsum muaj tib qhov nruj, ob peb pob qij txha, thiab lub zog tensile zoo, thiaj li ua tau raws li cov kev cai luam ntawv ntawm cov tshuab luam ntawv high-speed rotary.
Cov kev cai zoo rau cov ntawv coated: smoothness. Daim ntawv saum npoo yuav tsum du heev, yog li nws tuaj yeem ua rau tag nrho ntawm qhov screen tooj liab phaj thaum luam ntawv, thiaj li kom tau txais cov qauv zoo thiab meej nyias, uas yog qhov tseeb ntawm cov duab thiab ua rau lub qhov muag zoo.
Daim ntawv Whiteboard: Daim ntawv Whiteboard feem ntau yuav tsum nruj kev ntxhib los mos, du nto, tuab tuab, tsis muaj lint ntawm daim ntawv saum npoo, zoo absorbency thiab stretch npaum li cas kom tau 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 duab los qhia: Kraft duab los qhia yog ib daim duab los qhia tshwj xeeb uas siv rau cov khoom ntim sab nrauv, yog li qhov kev ntxhib los mos ntawm daim ntawv yuav tsum tawv, thiab lub zog tawg, lub nplhaib compressive zog thiab tearing degree yuav tsum siab. Tsis tas li ntawd, nws yuav tsum muaj kev tiv thaiv dej siab, yog li lub zog yuav tsis txo qis vim qhov nqus dej ntau, ua rau muaj kev puas tsuaj rau lub thawv thaum thauj dej hiav txwv lossis cia txias. Nws kuj yuav tsum muaj qee yam smoothness rau kraft cardboard uas yuav tsum tau siv rau kev luam ntawv.
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 yuav tsum tau ua kom muaj kev poob siab-pov thawj thiab siab-resistant peev ntawm lub thawv tsim. Yog li ntawd, bursting zog thiab lub nplhaib compressive zog (los yog tiaj tus compressive 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 tawg yuav tshwm sim thaum lub sij hawm corrugating. Cov dej ntau dhau yuav ua rau muaj teeb meem rau 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 daim ntawv saum npoo, sib xws hauv tuab, mos thiab ncab. Nws yuav o thiab ua softer tom qab soaked nyob rau hauv dej, thiab shrink ib txwm tom qab ziab. Tsis tas li ntawd, vim yog kev sib xyaw ua ke ntawm cellulose microcrystals nyob rau hauv cov kev taw qhia longitudinal, lub longitudinal zog ntawm daim ntawv yog loj, thiab transverse kev taw qhia yog me me, thiab yog hais tias muaj ib tug tawg, nws yuav tawg los ntawm ib tug heev me me quab yuam. Cellophane muaj cov yam ntxwv ntawm impermeability, roj impermeability thiab dej impermeability.
Offset printing ntawv: Offset ntawv yog siv rau ntau xim overprinting. Ntxiv nrog rau qhov yuav tsum tau ua kom zoo dawb thiab tsis muaj plua plav, nws muaj qhov xav tau ntau dua rau daim ntawv nruj, lub zog tensile thiab folding endurance. Thaum lub sij hawm luam ntawv, qhov saum npoo ntawm daim ntawv tsis tso lint, hmoov, los yog luam tawm. Nws muaj cov kev cai zoo ib yam li cov ntawv coated.
