Kev siv caustic soda hauv kev lag luam tshuaj tua kab.

Cov tshuaj tua kab

Cov tshuaj tua kab yog cov tshuaj siv hauv kev ua liaj ua teb los tiv thaiv thiab tswj cov kab mob ntawm cov nroj tsuag thiab cov kab tsuag thiab tswj kev loj hlob ntawm cov nroj tsuag. Siv dav hauv kev ua liaj ua teb, kev cog ntoo thiab kev yug tsiaj, kev tu ib puag ncig thiab hauv tsev neeg, kev tswj kab tsuag thiab kev tiv thaiv kab mob sib kis, kev tiv thaiv kab mob pwm thiab npauj npaim hauv cov khoom lag luam, thiab lwm yam.

Muaj ntau hom tshuaj tua kab, uas tuaj yeem muab faib ua cov tshuaj tua kab, cov tshuaj tua kab acaricides, cov tshuaj tua nas, cov tshuaj tua nematicides, cov tshuaj tua molluscicides, fungicides, herbicides, cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag, thiab lwm yam raws li lawv siv; lawv tuaj yeem muab faib ua cov zaub mov raws li qhov chaw ntawm cov khoom siv raw. Cov tshuaj tua kab (cov tshuaj tua kab inorganic), cov tshuaj tua kab biological (cov organic matter ntuj, cov kab mob me me, cov tshuaj tua kab mob, thiab lwm yam) thiab cov tshuaj tua kab synthesized, thiab lwm yam.

01 Cov dej qab zib causticua tus neeg sawv cev khi kua qaub

Cov tshuaj acidic yuav raug tsim tawm thaum lub sijhawm ua cov tshuaj tua kab, thiab cov kua qaub ntawm cov khoom yuav raug tshem tawm ntawm lub kaw lus ua cov tshuaj los ntawm kev ua kom cov caustic soda tsis muaj zog los txhawb cov tshuaj zoo. Txawm li cas los xij, cov caustic soda muaj qhov tshwm sim dai ntawm phab ntsa thaum siv, uas cuam tshuam rau qhov nrawm ntawm kev yaj.

Binhua granular sodium hydroxide siv lub tshuab granulation tshwj xeeb los hloov caustic soda los ntawm flakes mus rau granules, uas ua rau thaj chaw ntawm qhov chaw nce ntxiv, tiv thaiv cov khoom los ntawm agglomerating, thiab muab ib puag ncig alkaline ruaj khov dua.

02 Caustic soda muab ib puag ncig alkaline

Cov tshuaj lom neeg ntawm kev npaj tshuaj tua kab tsis ua tiav ib zaug, tab sis muaj ntau kauj ruam nruab nrab, qee qhov xav tau cov xwm txheej alkaline, uas xav tau kev yaj sai ntawm cov caustic soda khov kho kom ntseeg tau tias muaj cov caustic soda sib xws hauv lub kaw lus.

03 Kev ua kom tsis muaj zog nrog caustic soda

Caustic soda yog lub hauv paus muaj zog, thiab cov ionized hydroxide ions (OH-) hauv cov kua dej sib xyaw ua ke wnrog cov hydrogen ions (H+) ionized los ntawm cov kua qaub los ua dej (H2O), yog li ua rau pH ntawm cov tshuaj tsis muaj zog.
