Poov tshuaj hydroxide. Tau txais daim ntawv, siv, cov khoom

poov tshuaj hydroxide, kuj hu ua caustic potash, caustic potash, poov tshuaj hydroxide, poov tshuaj hydroxide, thiab ntau poov tshuaj alkali. Latin lub npe suab zoo li Koh poov tshuaj hydroxide. Lawv lwm cov ntaub ntawv thiab lub cev yam ntxwv ntawm no substance muaju tsis muaj xim nrog ib tug high degree ntawm hygroscopicity. Lub aqueous lub ntsiab ntawm Koh exhibits ib tug muaj zog alkaline cov tshuaj tiv thaiv. Los ntawm nqa tawm cov tshuaj tiv thaiv diaphragm electrolysis ntawm poov tshuaj tshuaj dawb tov ua nws npaj. poov tshuaj hydroxide, vim nws cov cim zog, tau pom ntau daim ntawv thov nyob rau hauv ntau yam teb ntawm tib neeg kev ua si.

Nyob rau hauv lub qhov muag ntawm Koh yog nyob rau hauv daim ntawv ntawm cov loj heev blocks tshuaj xws flakes, raws li tau zoo raws li nyob rau hauv daim ntawv ntawm granules, agglomerates los yog medium-qhov loj qhov me 40-50% kev daws teeb meem. Vim hais tias ntawm cov zog cov nqi ntawm cov tshuaj tebchaw muaj poov tshuaj nyob rau hauv lawv cov muaj pes tsawg leeg, yog tsis raws li ntau raws li natriesoderzhaschie. Nqe qhov teeb meem los ua tus yog vim li cas hais tias lawv yog siv nyob rau hauv tus neeg mob qhov twg qhov yuav tsum tau rau lub cev thiab tshuaj zog tsis muab natriesoderzhaschie tshuaj.

Nws yog kev ruaj ntseg kiag, uas tsis yog-flammable thiab tag resistant rau ib qho yooj yim tiv cav tseb, poov tshuaj hydroxide rau los ntawm cov tib neeg lub cev koom sib txuas ntawm lub thib ob chav kawm ntawv. Danger ua ingress caustic tshuaj nyob rau hauv cov txheej week thiab txawm nyob rau hauv tib neeg daim tawv nqaij. Qhov no tej zaum yuav ua rau loj tshuaj kub nyhiab thiab mob daim tawv nqaij kab mob. Ib qho txaus ntshai yog tshuaj yeeb dej caw yuav nkag mus kawm rau hauv lub qhov muag.

Muaj cov poov tshuaj hydroxide tshuaj tshwm sim los ntawm dispensing ib steel tej kas tham los yog tshwj xeeb ntim 100, 200 los yog 275 liters. Nyob rau hauv cov khoom daim ntawv rau poov tshuaj hydroxide yog siv huv si qhuav drums ntawm 50-180 dm. cu. Yuav kom tsim lub flaked khoom tau tso cai rau siv ntim nrog yas hnab twb qhib lawm, raws li tau zoo raws li polyethylene hnab.

Nyob rau hauv Lavxias teb sab Tshuaj Technology poov tshuaj hydroxide satisfies cov uas yuav tsum tau ntawm GOST 9285-78, mus sib ntshiab khoom muab GOST 24363-80. Vim ciam nyoos Koh nkag mus rau hauv cov nruj conformity rau hauv tus txheej txheem CAS 1310-58-3.

Tshuaj neutralization cov tshuaj tiv thaiv nyob rau hauv uas lub sulfuric acid yuav hnov mob, kom tau poov tshuaj hydroxide thiab ntsev dej yog lub npe hu rau sawv daws hauv tsev kawm ntawv. Tab sis muaj lwm yam uas txawv thaj chaw ntawm Koh, uas nyob rau qhov no substance ib tug ntau ntawm cov ntaub ntawv sau npe. Nws yog siv, tsuas yog rau cov neutralization ntawm acids, txawm nyob rau hauv alkaline roj teeb, nrog catalysis, xab npum, drilling kua, dyes, chiv.

Yog tsis muaj kev siv cov poov tshuaj hydroxide los yog tsis tswj zaub mov kev lag luam, tsis muaj roj tu, los yog co los yog refinery los yog pharmaceuticals. Nws yog siv nyob rau hauv qhov siv thiab ua ib tug ntau yam ntawm cov organic thiab inorganic cov ntaub ntawv, daim ntawv, tshuaj tua kab, poov tshuaj carbonate, poov tshuaj tebchaw, soaps, hluavtaws roj hmab.

Ib tug ntawm cov tseem ceeb tshaj plaws teb ntawm kev siv ntawm poov tshuaj hydroxide yog qhov siv thiab ua cov mos mos xab npum. Detergents, zawv plaub hau, shaving cream, bleaches npaj siv Koh. Ib qho tseem ceeb daim ntawv thov ntawm no cov ntaub ntawv uas yog muab ib tug set ntawm kev lag luam uas cog noob poov tshuaj ntsev.

Nyob rau hauv zus tau tej cov poov tshuaj permanganate nteg txheej txheem fusion nrog caustic potash thiab tom ntej manganese dioxide oxidation ntawm lub poov tshuaj manganate tau nyob rau hauv lub chamber ntawm lub electrolysis. Rau poov tshuaj dichromate yuav siv tau ib txoj kev zoo li ntawd piav saum toj no. Tiam sis feem ntau nws yog manufactured los ntawm fusion ntawm finely av chromite ore hydroxide (lwm - carbonate) ntawm poov tshuaj, ua raws li los ntawm raug acid nyob rau hauv lub tau chromate.

Siv Koh caustic peev xwm ua tau teeb meem loj tau nyob rau hauv zus tau tej cov ib tug ntau ntawm cov xim, thiab ib co ntawm cov organic tebchaw. Nws manifests nws tus kheej raws li ib tug zoo adsorbent roj rau dehydrating neeg sawv cev, ib yam khoom uas provoking tsis insoluble hydroxides nyob rau hauv lub ntsha roj teeb alkaline hom.

Thiab qhov no yog cia li ib nyuag daim ntawv teev cov kev qhia txog ntawm kev siv technology tshiab dab, uas siv Koh.
