Potassium Humate Tus Cawv Ntawm Kev Ncauj Loj

1, qhov kev sib tw ntawm kev ua vaj tse. Mixed nrog potassium hydroxide pob zeb, Potassium Humate nyob rau hauv chav tsev txuag kev txuag, thawj ob lub hlis ntawm contraction yuav me ntsis loj, peb lub hlis tom qab lub admixture ntawm qhob shrinkage me tshaj li nws ntxiv.

2, tiv thaiv-thaw. Potassium hydroxide tov nrog lub pob zeb, lub siab ceev tshaj lub sij hawm tsis loj, qhia tias nws cov compactness, thiab yog li zoo dua anti-freeze-thaw kev ua tau zoo.

3, cov khoom siv sib xyaw ua ke. Potassium hydroxide nrog ua vaj tse, Potassium Humate nws cov ntawv cog lus impermeability tshaj qhov ntxiv ntawm coagulation ntawm lub impermeability ntawm daim ntawv lo yog siab dua.

4, lub creep ntawm qhob. Lub degree ntawm creep ntawm qhob tov nrog potassium hydroxide yog me dua li ntawm cov pob zeb uas tsis yog-pob zeb, thiab cov coefficient ntawm creep yog me me, Potassium Humate kom nws tuav tau qhov kev tsim nyog ua thaum siv hauv prestressed melee av.

5, lwm yam khoom, ntxiv rau potassium hydroxide qhob carbonation thiab corrosion, Potassium Humate thiab lwm yam. Feem ntau, tsis siv li, tsis pom muaj teebmeem phiv.

Nrog potassium hydroxide tov ua ntej thawj coj tsis tau ncaj qha rau potassium hydroxide khoom rau hauv lub volumetric hwj, vim hais tias cov potassium hydroxide yaj hauv dej yuav tsum exothermic, Potassium Humate nws yuav tsum tau weighed ib yam nqi ntawm potassium hydroxide mus rau hauv lub me beaker Tus

Siv 5.8 mus rau 6 gram ntawm potassium hydroxide mus rau 1000 ml ntawm dej distilled, Potassium Humate distilled dej ua ntej siv rau carbon dioxide evaporation, noj 3 grams potassium hydroxide mus rau hauv lub me me lub raj mis thiab ces mus rau hauv 100 ml ntawm dej distilled.

Thiab ces maj mam txhaj rau hauv lub rhaub kom tshem tawm cov CO2 thiab tau txias cov dej / cov dej deionized, thiab tas li stirring nrog iav qws kom potassium hydroxide khoom kiag li yaj, Potassium Humate thiab ces mus rau nws lub ntuj txias, nrog ib khob qws rau hauv lub volumetric hwj.

Thiab tom qab ntawd tau raug rhaub kom tshem tawm cov CO2 thiab tau txias dej / dej deionized kom ntxuav lub khob thiab beaker 3 mus rau 4 zaug thiab cov tshuaj pleev rau hauv lub khob dej volumetric, thiab ces lub cev muaj peev xwm ntawm lub raj mis.

Txog li ib nrab ib teev tom qab, kev daws ntawm potassium hydroxide yog qhov ua tau zoo.

Yog vim li cas rau cov nyhuv ntawm cov khoom potassium hydroxide turbidity yog tias cov potassium hydroxide reagent muaj carbonate. Thaum lub poov tshuaj hydroxide reagent ntxiv rau cawv, Potassium Humate lub potassium carbonate thiab sodium carbonate uas yog insoluble nyob rau hauv dej cawv yog tshem tawm hauv cawv, ua rau turbidity ntawm kev daws. Lub ntsiab ntawm kev tiv thaiv lub turbidity ntawm kev daws yog los tshem tawm cov carbonate.

Yog hais tias koj xav kom tshem tawm cov potassium carbonate nyob rau hauv tus qauv tov potassium carbonate, cia li siv cov concentration ntawm potassium hydroxide reagents, Potassium Humate thiab tom qab ntxiv methanol, co, muab nws ib sab rau ib lub lim tiam kom txog thaum cov tshuaj kom meej meej, pov tseg maj mam.

Tab sis qhov tshem tawm ntawm carbonates nyob rau hauv cov khoom potassium hydroxide, Potassium Humate siv tsis tau cov txuj ci saum toj no, vim hais tias 95% ntawm ethanol dej cov ntsiab lus siab, yuav muaj ib feem ntawm carbonate yaj hauv dej, nws yog qhov nyuaj cais, ces yuav tsum cov kua tshuaj kua tshuaj khej hydroxide ntxiv 10% ntawm barium chloride kua (1L txog 3 5mL barium chloride kua), sawv ntsug rau li ob lub lis piam, Potassium Humate kom txog thaum cov tshuaj muaj tseeb, lim, muab pov tseg kom sai, noj cov tshuaj.
