Cov Tswv Yim Tseem Ceeb Ntawm Cov Khoom Uas Tsom Khoom Tej Khoom Siv Nrog Lub Khaws Ntawv

Cov ntsiab lus tseem ceeb ntawm kev tsim khoom noj khoom ntawv nrog ntawv pov tseg
Ib puag ncig-phooj ywg Hnab
Ib puag ncig-phooj ywg Hnab
1. Rau cov cuab yeej qhuav, nws tau pom tias tag nrho cov neeg Asmeskas pov tseg los yog European pov tseg yuav tsum raug siv los tswj kev tsim cov ntawv raws li daim ntawv A lossis B daim ntawv pov thawj. Cov txheej txheem npoo npoo yuav tau dai, lossis tsis muaj peev xwm dai noodles, qhov no yuav tsum yog raws li losis tsis sau cov qauv qauv thiab cov ntawv tshaj tawm. Daim ntawv muaj peev xwm nyob ntawm 135 ~ 150 grams / m2. 25 * 20 * 15cm ntawv hnab dais ib qhov hnyav txog 8 ~ 15 kilograms.
2. Cov ntawv pov tseg tag nrho kuj siv tau rau cov khoom siv uas yuav tsum tau dais cov dej. Tsuas yog raws li tus txheej txheem saum toj no, ntxiv ib qho qis qis zog 0.5 ~ 1.0%, lub zog ntub nce mus txog 10 ~ 15%.
3. rau cov nqaij los yog lwm yam ntub, tuaj yeem siv tau thoob plaws hauv cov ntawv pov tseg rau khoom muag. Muaj ib qho yuav tsum tau ntxiv rau hauv cov txheej txheem ntawm slurry papermaking los yog coated nyob rau saum npoo ntawm cov phooj ywg-phooj ywg roj pov thawj. Nws kuj siv tau los tsuag tsuag dej lossis ploj zom me ntsis ob zaug nyob rau hauv lub zog ntawm daim ntawv.
4. Thaum twg daim ntawv luam tau muab luam tawm, ob txheej ntawm slurry raug ntxiv rau cov dej siv cov xuab zeb soluble nrog cov ntsiab lus ntawm textile. Thawj txheej ntawm daim ntawv tuaj yeem ncav lub zog ntawm plaub cov ntaub ntawv ntawm kraft paper, thiab nws muaj peev xwm hloov tau hloov cov ntawv cement zoo tib yam. Ib yam li ntawd, tib daim ntawv yuav siv tau rau ntawm lub hnab ntim khoom.
5. Cov khoom no muaj kev nyab xeeb thiab ib puag ncig tus phooj ywg.
