Gluconic acid thiab sodium gluconate: Siv nyob rau hauv kev lag luam

Gluconic acid yog tsim thaum lub sij hawm oxidation aldegidogruppy monosaccharides (glucose). Acid sawv cev los ntawm reacting alkali hlau salts ntawm carboxylic acids ntaub ntawv - gluconates. Gluconic acid yog ib qho tseem ceeb ntawm tshuaj pleev ib ce, uas yog siv rau cov nti. Hais tias tivthaiv tau yooj yim kov yeej ntawm daim tawv nqaij barrier, permeates ntawm daim tawv nqaij thiab tsis ua phiv. Uas yog vim li cas gluconic acid - ib tug indispensable lub cuab tam rau hypersensitive thiab kev laus rau daim tawv nqaij saib xyuas khoom. Tshwv nrog acid tsub kom cov tawv nqaij elasticity, pab txoj kev ntawm lub ntsej muag nkhaus, thiaj li muaj cov heev ntawm wrinkles, restores cov teeb meem muaj nuj nqi ntawm daim tawv nqaij. Nws yuav tsum tau muab sau tseg hais tias qhov no acid yog tseem siv tau raws li ib tug acidulant, antioxidant synergist, ib tug acidity regulator.

sodium gluconate (C6H11O7Na mis) - ib tug complexing neeg sawv cev rau hlau ions (calcium, iron, txhuas, manganese) nyob rau hauv industrial alkaline xab npum daws teeb meem. Qhov no feem yog siv nyob rau hauv cov kua formulations, nyob rau hauv ua ke nrog nrog rau lwm cov ingridentami xws li phosphorus thiab sodium silicate, nto active neeg thiab sodium hydroxide. Gluconic acid (sodium gluconate) ntxiv mus rau qhov kev daws teeb meem reacted uas muaj calcium, li no txoj kev ua ib chelate compound. Surfactants yog feem ntau zoo nyob rau hauv cov mos mos dej los yog demineralized. Txij li thaum lub demineralization txheej txheem nws tus kheej yog kim heev thiab qho kev ntau zoo tshuaj no yog ntxiv rau ib tug formulation ntawm detergents sodium gluconate. Qhov kev txiav txim ntawm sodium hydroxide complement silicates, lawv nce lub alkalinity ntawm cov tshuaj tiv thaiv thiab hlau corrosion. Sodium gluconate - qhov zoo tshaj plaws ib tug complexing neeg sawv cev los ua ib tug sib tov ntawm alkali. Nws yog siv nyob rau hauv lub formulation ntawm xab npum fwj. Qhov no yog vim high school kuj mus hydrolysis thiab biodegradability.

Gluconic acid yog ntxiv rau lub ntsiab rau lub tshuab ntxhua khaub iav khoom. Raws li ib tug dav dav txoj cai, nyob tus yeees ntawm cov formulation nyob rau hauv lub loj ntawm lub deposits thiab cov dej hardness. Sodium gluconate yog ntxiv rau lub pob zeb sib tov. Nws yog pom tias ntxiv no tivthaiv slows qhov chaw txheej txheem ntawm vaj tse, nws pab cov ductility. Sodium gluconate yog nkag adsorbed rau ntawm qhov chaw ntawm MAAs hais, nyob rau hauv kev sib cuag nrog dej tiv thaiv lawv kev sib cuag nrog nws, li no tseg lub pob zeb ruaj khov txheej txheem. Nyob rau hauv cov tshuaj tiv thaiv ntawm hais tias tshuaj uas muaj calcium ions tsim insoluble complex calcium gluconate rau ntawm qhov chaw ntawm MAAs hais. Raws li ib tug tshwm sim ntawm no synergy nws slows cov co txheej txheem, ua nyob rau hauv ib qho kev nce nyob rau hauv hardening lub sij hawm. Cov tsim ntawm ntev fibers microcrystalline pab rau kom tus neeg kho tshuab zog ntawm mortars.

Los ntawm kev siv ntawm complexing agents yog raug rho tawm calcium ions, uas nyob rau hauv lem tiv thaiv lub tsim ntawm muaju. Los ntawm kev siv ntawm sodium gluconate pab txoj kev dispersion ntawm lub MAAs hais nyob rau hauv lub ntoos sib xyaw pab txoj kev tso zis. Cov dab yuav txo tau cov dej concentration. Nws yog muaj pov thawj hais tias muaj cov microcrystalline ntev fibers ho tsub kom lub dag lub zog ntawm qhob tom qab 28 hnub. Siv complexing cov neeg ua hauj thiaj li muaj cov concentration ntawm cov dej nyob hauv lub mixtures, uas zoo influences lub dag lub zog, hardness thiab ductility ntawm qhob.

Nyob rau hauv lub metallurgical kev lag luam C6H11O7Na siv raws li ib tug chelating neeg sawv cev uas binds hlau ions, tiv thaiv lub deposition ntawm hydroxide ntawm txhuas nyob rau hauv tej chaw. Thaum pickling steel sawv cev biosoedinenie tiv thaiv deposition ntawm hlau salts nyob rau hauv cov deposition los xij los yog da. Qhov no zoo heev pab txoj kev nto lub xeev ntawm cov hlau.
