Hauv kev pom tias qhov dhau ib nrab xyoo dhau los, tib neeg kev vam meej tau nce qib sai thiab siv tsis tau ntawm cov khoom siv ib puag ncig, ua rau muaj kev hloov pauv thiab rhuav tshem ib puag ncig thiab maj mam cuam tshuam rau tib neeg lub neej. Nws tau pom tias tsuas yog cog ntoo loj dav tuaj yeem txo cov txiaj ntsig ntawm kev puas tsuaj puag ncig. Txawm li cas los xij, txij li daim ntawv ntuj xav tau los ntawm tib neeg kev vam meej, cov cartons thiab pallets xav tau rau kev txhim kho kev lag luam, txhua tus siv cov ntoo ntoo ua raw khoom. Yog tias koj tsis sim hloov daim ntawv sau ntuj, txawm hais tias qhov kev siv ntawm Kev Cog Lus Cog Ntoo, Kuv ntseeg tias cov ntoo yuav qis dua qhov tsis txhob nce ntxiv. Nws tsis tuaj yeem ua tiav lub hom phiaj ntawm kev cog ntoo ntau kom txo qis ib puag ncig kev puas tsuaj.
Hauv kev pom txog qhov no, Nanya pib kev tshawb fawb thiab kev tsim kho xyoo 1991, thiab tom qab xya xyoo siv kaum tawm lab nyiaj, thaum kawg nws tau tsim tsa lub Tsib Hlis 1998. Cov ntawv hluavtaws nrog PP ua cov khoom tseem ceeb muaj qis dua kev sib tsoo, zoo dua kev coj nruj, thiab zoo opacity dua li cov ntawv hluavtaws. Nws feem ntau yuav hloov cov ntawv hluavtaws ntawm cov ntawv ntuj thiab tau sau npe ua" Pearl Ntawv" ;. Cov ntawv hluavtaws feem ntau yog hais txog cov ntawv tsis muaj fiber ntau, ntawv yas. Ntxiv rau cov khoom siv tseem ceeb (polypropylene lossis polyolefin), cov ntawv hluavtaws kuj tseem suav nrog cov khoom ua tau zoo thiab cov tshuaj silicon lossis kua qaub.
Cov ntawv muaj pes tsawg leeg ntawm cov ntawv hlaws yog tib yam li cov ntawv dawb dawb, uas yog, nws yog li ntawm peb ntu: cov hauv qab fiber, muab tub lim thiab txheej txheej saum npoo. Qhov sib txawv ntawm cov ntawv sau dawb dua ntawm daim phiaj xim yog tias txheej txheej saum npoo muaj cov nplais uas ua rau cov nyhuv pearlescent. Qhov kev faib tawm yog suav nrog titanium dioxide (lossis lwm cov hlau oxides) thiab mica hais. Cov mica hais yog tsim los ntawm qhwv los ntawm titanium dioxide (lossis lwm yam hlau hlau), thiab tus qauv yog nyob rau hauv daim ntawv ntawm plaub ya ri.
Nta
① Tsis tshua muaj lub zog siv hluav taws xob tsis zoo thiab ua tsis zoo cov xim adsorption
Vim tias qhov saum npoo ntawm cov ntawv teeb tsa ntawm mica thiab titanium dioxide (lossis lwm cov hlau oxides) yog tus, thiab daim ntawv saum npoo yog qhov yuav tsum tau sib luag thaum lub sijhawm papermaking txheej txheem (yog li ntawd cov nyhuv pearlescent tuaj yeem nkag mus zoo dua cov txheej rau hauv tib neeg qhov muag), daim ntawv pearlescent muaj ntau dua li qhov zoo tshaj plaws Cov nplais hluav taws xob hauv cov ntawv dawb yog qhov me dua, thiab tus number case tsis yooj yim los lo thiab nqus thiab tsis yooj yim qhuav thaum luam ntawv.
Cov pearlescent effect nyob rau saum npoo tau yooj yim rhuav tshem.
Hauv ntawv tsis sib thooj, ntawv pearlescent muaj cov nqi ntau dua.
