Methyl cellulose yog lub ntsiab lus ntawm sodium carboxymethyl cellulose.Nws yog tsuas yog siv rau hauv cov khoom noj, kev tsim kho, tshuaj, ceramics, roj teeb, mining, coatings, papermaking, ntxuav, tshuaj txhuam hniav txhua hnub, textile printing thiab dyeing, roj drilling, thiab lwm yam nyob rau hauv ib lub teb.Lub luag haujlwm tseem ceeb yog ua kom cov thickener, dej tuav tus neeg sawv cev, khi, roj nplua nyeem, tshem tawm tus neeg sawv cev, emulsifier, cov khoom siv roj ntsha, cov ntsiav tshuaj matrix, thiab lwm yam. Yuav ua li cas methyl cellulose yuav tsum tau faib ua feem thaum siv?
1. Methylcellulose nws tus kheej yog cov hmoov qhuav qhuav, uas tsis tuaj yeem siv ncaj qha rau hauv kev lag luam.Nws yuav tsum tau yaj hauv dej ua ntej los tsim cov kua nplaum pob tshab ua ntej nws tuaj yeem tov nrog tshuaj khib thiab tom qab ntawd siv rau qee qhov kev kho mob, xws li cov vuas pasting.
2. Qhov piv ntawm methyl cellulose yog dab tsi?Hmoov: dej yuav tsum tau ua tiav ib zaug raws li qhov sib piv ntawm 1: 150-200, thiab tom qab ntawd muab cov hmoov sib tov, thaum ntxiv PMC qhuav hmoov thaum nplawm, thiab nws tuaj yeem siv tom qab siv li 1 teev.
3. Yog tias methyl cellulose siv rau kev kho pob zeb sib txuas, cov kua nplaum yuav tsum ua raws → kua nplaum: cement = 1: 2.
4. Yog tias methyl cellulose siv los ua cov cement mortar los tiv thaiv kev tawg, cov kua nplaum yuav tsum tau ua raws → kua nplaum: cement: xuab zeb = 1: 3: 6.
Peb yuav tsum tau xyuam xim rau qee qhov teeb meem thaum siv methyl cellulose:
1. Ua ntej siv cov tshuaj methyl cellulose, koj yuav tsum xub saib cov specifications thiab qauv.Cov qauv sib txawv siv ntau txoj hauv kev: thaum pH> 10 lossis <5, viscosity ntawm cov kua nplaum kuj tsawg.Qhov kev ua tau zoo yog qhov ruaj khov tshaj plaws thaum pH = 7, thiab cov viscosity yuav nce sai heev thaum kub qis dua 20 ° C;Thaum qhov kub siab tshaj 80 ° C, lub colloid yuav denatured tom qab cua sov ntev, tab sis cov viscosity yuav poob qis heev.
2. Methyl cellulose tuaj yeem npaj nrog dej txias lossis dej kub raws li qhov sib piv.Thaum npaj, koj yuav tsum tau ntxiv dej thaum stirring.Nco ntsoov ntxiv tag nrho cov dej thiab PMC qhuav hmoov ib zaug.Nws yog ib qho tsim nyog sau cia tias lub hauv paus txheej uas yuav tsum tau sib koom ua ke yuav tsum tau muab ntxuav ua ntej, thiab qee qhov av, cov roj stains, thiab cov khaubncaws sab nraud povtseg yuav tsum tau ua raws sijhawm.
