Raws li hom tshiab ntawm tus neeg sawv cev muaj zog thaum ntxov, calcium formateTsis tsuas yog ua kom lub zog ntawm cov cement, tab sis kuj zam qhov kev teeb tsa qeeb dhau ntawm kev tsim kho lub caij ntuj no lossis qis qis thiab cov av noo, nws ua rau muaj txiaj ntsig zoo rau lub zog thaum ntxov ntawm cov khoom cement yuav tsum tau muab tso rau hauv kev siv sai li sai tau. Tau ntev, calcium chloride tau siv dav hauv engineering, tab sis nws tuaj yeem corrode steel bar, chlorine-dawb coagulant tau tsim nyob rau hauv tsev thiab txawv teb chaws, thiab calcium formate yog ib yam tshiab ntawm cov khoom siv thaum ntxov, nws tuaj yeem ua tau zoo. hydration ntawm tricalcium silicate C3s nyob rau hauv cov cement thiab nce lub zog thaum ntxov ntawm cov cement mortar, tab sis nws yuav tsis ua rau corrosion rau steel tuav thiab yuav tsis ua rau ib puag ncig muaj kuab paug, yog li ntawd, nws kuj yog lug siv nyob rau hauv roj teb drilling thiab cementing. Cov yam ntxwv ntawm cov khoom: ua kom lub zog ntawm cov cement, ua kom lub sijhawm tsim kho. Shorten lub sij hawm teem, thaum ntxov molding. Txhim kho lub zog thaum ntxov ntawm mortar ntawm qhov kub thiab txias. Antifreeze thiab antirust. Cov ntaub ntawv tshuaj muaj zog thiab cov yam ntxwv calcium formate yog cov hmoov dawb lossis greyish dawb crystalline hmoov. Raws li tus qauv kev kho mob, cov khoom no tuaj yeem ua qhov kev teeb tsa zaum kawg hauv 4 teev. Lub zog ntawm cam khwb cia-hauv-qhov chaw pob zeb tuaj yeem ncav cuag 5MPA tom qab 8 teev, thiab cov pob zeb cam khwb cia hauv qhov chaw tuaj yeem ua tiav demoulded. Thaum ua kom ntseeg tau lub zog thaum ntxov ntawm mortar thiab pob zeb, nws tuaj yeem ua rau lub zog lig ntawm mortar thiab pob zeb nce ib txwm thiab tsis muaj kev puas tsuaj rau lwm yam khoom ntawm mortar thiab pob zeb.

Yav dhau los: Dab tsi yog kev siv ntawm formic acid

Tom ntej: Formic acid, tseem hu ua formic acid, yog ib hom carboxylic acid, tab sis kuj nyob rau hauv cov xwm ntawm cov yooj yim carboxylic acid, formic acid yog dav siv nyob rau hauv cov tshuaj, textile, dyeing, tawv, luam ntawv thiab lwm yam lag luam, nrog rau txoj kev loj hlob ntawm cov tshuaj. lub sij hawm, formic acid kuj tau siv dav dua. Kev siv cov formic acid: 1, nyob rau hauv kev lag luam kws tshuaj, formic acid muaj * rau ntau yam kev siv, peb zus tau tej cov formic acid 50% yog siv rau kev tsim tshuaj. 2. Hauv kev lag luam tshuaj, formic acid tuaj yeem ncav cuag yuav luag 70% ntawm cov khoom siv tshuaj lom neeg thiab cov khoom siv pabcuam, xws li formate, hnyav-raws li kev lag luam tshuaj. Kev lag luam tshuaj tua kab kuj xav tau ntau cov formic acid, feem ntau yog siv los tsim tshuaj tua kab thiab tshuaj tua kab. 4. Siv los ua tanning tus neeg sawv cev hauv kev lag luam tawv
