Cov tshuaj lom neeg lub npe ntawm cov dej caw nplij cov dej qab zib, cov khoom siv benyustic dej qab zib thiab sodium dej qab zib, caustic dej qab zib thiab caustic dej qab zib. Nws yog ib qho kev sib xyaw ua ke nrog tshuaj lom neeg Naoh. Nws yog cov corrosive heev thiab yooj yim soluble hauv dej. Nws cov kua aqueous yog cov alkaline muaj tseeb thiab tuaj yeem tig phenolphatalein liab. Sodium hydroxide yog ib feem ntau siv alkali thiab ib qho ntawm cov tshuaj num tseem ceeb hauv tshuaj lom neeg siv tshuaj. Nws cov kev daws teeb meem yuav siv tau ua cov kua ntxuav. Khoom sodium hydroxide feem ntau muab faib ua peb daim ntawv, uas yog flake caustic dej qab zib, granular caustic qab zib thiab khoom caustic dej qab zib. Lawv qhov sib txawv tseem ceeb nyob rau hauv daim ntawv, cov txheej txheem ntau lawm, ntim khoom thiab siv.
01: Zoo sib xws 1. Cov ntaub ntawv raw siv nyob rau hauv kev tsim khoom yog tib yam, ob leeg yog ua los ntawm kua alkali; 2. Cov qauv molecular zoo ib yam, ob leeg yog Naoh, tib cov tshuaj; Lub ntsiab lus melting (318.4 degrees) thiab boiling point (1390 degrees) yog tib yam. 3. Ob leeg yog corrosive heev, tuaj yeem hlawv cov tawv nqaij sai, thiab yaj hauv dej.
02: Qhov sib txawv 1. Cov khoom siv siv hauv cov txheej txheem ntau lawm yog txawv. Fleustic dej qab zib yog seem los ntawm caustic dej qab zib tshuab thiab tom qab ntawd txias thiab ntim rau hauv lub hnab. Granular Caus Soda yog tsim los ntawm cov khoom siv tshuaj tsuag granulation, thiab cov khoom siv caustic yog thauj mus rau cov khoom siv caustic sodle siv lub raj xa dej. 2. Cov tsos sab nraud ntawm cov khoom yog txawv. Fleustic dej qab zib yog cov nplaim hluavtaws, granular caustic dej qab zib yog lub ntsej muag ci ntsa iab, thiab cov khoom noj qab zib thiab khoom noj tag nrho.
3. Cov ntim tau txawv: ①. Caustic Soda Flakes Andilic Dej Nplog Granules: Feem ntau siv 25kg yas woven hnab, uas yog lub luag haujlwm hauv lub luag haujlwm hauv kev ua pov thawj noo noo. Nws yuav tsum muab khaws cia rau hauv qhov cua thiab qhuav warehouse lossis los. Cov ntim ntim yuav tsum ua kom tiav thiab ntim khoom. Nws yuav tsum tsis txhob khaws cia lossis thauj ua ke nrog cov khoom siv hluav taws xob thiab cov acids.
②. Khoom Noj Capustic Khoom Noj: Muaj cov khoom noj khoom haus caustic dej qab zib yuav tsum tau muab khi thiab ntim rau hauv cov ntoo hlau. Lub thoob thaiv phab ntsa tuab yuav tsum muaj ntau dua 0.5 hli thiab lub siab tsis kam yuav tsum muaj ntau tshaj 0.5pa. Lub hau kev yuav tsum tau muab khi. Qhov nyhav ntawm txhua lub barrel yog 200kg. Yuav tsum muaj ib qho "corrosive yam khoom" cim ntawm pob. 4. Sib txawv siv: Flake Caus Caustic Soda feem ntau yog siv hauv kev lag luam tshuaj, luam ntawv thiab dowage kho, tshuaj tua kab, khoom siv hluav taws xob, thiab lwm yam .; Granular Caus Soda yog tsuas yog siv hauv kev lag luam tshuaj xws li tshuaj thiab cov tshuaj pleev ib ce. Nws yog qhov yooj yim dua los siv cov dej qab zib caustic ntawm cov dej qab zib hauv chav kuaj mov dua li nplaim hluav taws. Khoom noj muaj zog caustic yog feem ntau siv hauv kev lag luam tshuaj;
03: Kev Taw Qhia Taw Qhia
1. Flake caustic dej qab zib yog dawb, translucent, flaky khoom. Nws yog cov khoom siv tshuaj lom neeg yooj yim. Nws tuaj yeem raug siv los ua cov kua qaub neutralization, tus neeg sawv cev ua ntej, tus neeg tsav tsheb los nag, ib qho tshuaj ntxuav, thiab lwm yam nws muaj ntau yam kev siv. 2. Granular caustic dej qab zib yog granular caustic qab zib dej qab zib, tseem hu ua raws li cov roj hlaws caustic dej qab zib. Granular Caus Soda tuaj yeem muab faib ua cov ntxhib cov khoom noj qab zib thiab cov khoom noj zoo nkauj raws li qhov loj me. Lub particle me me ntawm cov nqaij mos zoo nkauj heev yog li 0.7mm, thiab nws cov duab zoo heev rau kev ntxuav hmoov. Ntawm cov khoom noj khoom haus kom meej, ua kom muaj cov dej qab zib thiab cov dej qab zib zoo nkauj tshaj plaws thiab siv cov khoom noj tau zoo tshaj plaws. Granular Caus Soda yog yooj yim siv dua li flake caustic dej qab zib, tab sis cov txheej txheem ntau lawm ntawm cov khoom noj qab zib grantic yog qhov nyuaj dua li ntawm flake caustic dej qab zib. Yog li ntawd, tus nqi ntawm Granular Caus Soda yog ib txwm muaj siab tshaj li ntawm Flake Caus Soda. Nyob rau hauv feem ntau muaj kev muaj cov khoom noj qab zib, granular Caus Soda yog zoo dua rau lwm lub sijhawm, yog li nws yog cov txheej txheem sib xyaw los ntawm cov khoom qab zib Grantlic caustics xws li flake caustic dej qab zib.
