Qhov cuam tshuam ntawm Iron Free Aluminium Sulfate Ntawm Kev Lag Luam Ntawv

Hauv kev lag luam papermaking, kev siv cov hlau tsis muaj txhuas sulfate feem ntau tuaj yeem muab faib ua ntau hom, thiab feem ntau nws tuaj yeem siv los ua papermaking additive, tuav thiab pom kev pab, daim ntawv reinforcement agent, dej kho tus neeg saib xyuas, thiab lwm yam. Thiab thaum peb siv. nws, aluminium sulfate tsis muaj hlau tsis muaj hlau, yog li nws yuav tsis muaj kev cuam tshuam tsis zoo rau cov ntawv dawb thaum siv hauv cov ntawv dawb.
1. Cov ntaub ntawv khaws cia thiab pom kev pab: Hlau tsis muaj txhuas sulfate muaj kev tuav zoo heev thiab pom cov nyhuv ntawm daim ntawv.
2. Paper enhancer: Tom qab siv cov khoom no, nws yuav tsis muaj kev phiv los ntawm cov xim ntawm cov ntawv dawb, thiab nws kuj tau txhim kho ntau yam khoom ntawm daim ntawv dawb. Yog li ntawd, nws yog heev haum rau siv nyob rau hauv zoo heev daim ntawv ntau lawm.
3. Qhov sib ntxiv ntawm cov hlau tsis muaj txhuas sulfate rau papermaking pulp feem ntau txo nws txoj kev cuam tshuam rau pH tus nqi ntawm cov pulp.
4. Cov khoom no tsim nyog rau qhov dav pH ntau dua thaum lub sij hawm papermaking sizing txheej txheem. Ntxiv mus, hlau tsis muaj txhuas sulfate yog ib tug sizing tus neeg sawv cev haum rau acidic thiab nruab nrab ib puag ncig, nrog qis corrosiveness rau papermaking systems thiab yooj yim kho cov dej khib nyiab generated; Hlau uas muaj txhuas sulfate tsuas yog haum rau sizing nyob rau hauv acidic ib puag ncig, thiab hlau uas muaj txhuas sulfate feem ntau muaj tej yam cuam tshuam rau daim ntawv zoo thiab khoom siv.
5. Feem ntau hais lus, hlau tsis muaj txhuas sulfate tuaj yeem ua rau kom tawv tawv ntawm daim ntawv.
Cov saum toj no yog ua tiav cov lus qhia txog kev siv hlau tsis muaj txhuas sulfate hauv kev lag luam papermaking. Nws yog tsuas yog siv los ua tus neeg sawv cev sizing rau papermaking, nrog rau flocculant rau cov dej haus, dej haus, thiab kev kho dej khib nyiab. Nws tseem yog cov khoom siv raw rau kev tsim cov gemstones thiab lwm yam txhuas ntsev xws li ammonium alum, potassium alum, thiab refined aluminium sulfate. Tsis tas li ntawd, aluminium sulfate kuj tau siv dav hauv kev tsim cov khoom lag luam zoo tshaj plaws, cov roj av deodorizing thiab decolorizing cov neeg ua haujlwm, cov khoom siv dej tsis zoo, cov ntawv forging whitening, titanium dioxide post zaj duab xis kev kho mob, thiab catalyst nqa.
