1.Caustic soda qhia
Caustic soda (Sodium hydroxide, NaOH) yog lub hauv paus muaj zog siv hauv kev lag luam. Nws yog ib qho tseem ceeb raw khoom rau kev tsim xab npum, hluavtaws fibers (xws li nylon), ntawv, iav, thiab lwm yam. Nws ua hauj lwm raws li ib tug flux nyob rau hauv ore smelting thiab hlau extraction, thiab kuj yog siv nyob rau hauv cov hlau nto kho. Hauv kev lag luam khoom noj khoom haus, caustic soda yog siv rau kev hloov pH, tshem tawm cov tev, impurities, thiab lwm yam. Nws yog ib qho tseem ceeb hauv ntau cov tshuaj ntxuav, siv rau tshem cov roj stains, av, thiab lwm yam., feem ntau pom muaj nyob rau hauv cov ntxhua khaub ncaws detergents, lim dej huv. , thiab lwm yam. Nyob rau hauv 2022, tag nrho lub ntiaj teb no caustic soda muaj peev xwm nyob ze rau 87million ton.
2.Kev piav qhia ntawm Chlor Alkali Cog
Tam sim no, ion-exchange membrane electrolysis txheej txheem yog dav siv los tsim caustic soda. Tag nrho cov nroj tsuag caustic soda tuaj yeem muab faib ua brine seem, seem electrolysis, by-product (H2, Cl2) seem kev kho mob, seem concentration. Nyob rau hauv lub brine seem, cov ntsev nyoos yog yaj, tshuaj purified, lim, thiab undergoes txheej txheem xws li ion txauv los xyuas kom meej tias ntau yam indicators as ntawm lub brine raws li qhov yuav tsum tau ntawm cov electrolyzer. Cov brine tsim nyog raug xa mus rau electrolyzer rau electrolysis. Ntawm lub cathode, caustic soda thiab hydrogen gas yog tsim, thaum nyob rau ntawm anode, chlorine gas yog tsim. Lub dilute caustic soda yuav raug xa mus rau seem concentration los tsim cov khoom caustic soda. Cov khoom caustic soda feem ntau yog muag li flakes, tshuaj thiab cam khwb cia blocks. Cov by-product chlorine gas thiab hydrogen gas tom qab txias yuav raug xa mus rau graphite rauv rau hluavtaws hydrochloric acid. Cov roj chlorine tshaj tawm tom qab ziab, compressing los ua kua chlorine. Cov roj chlorine kuj tuaj yeem siv los tsim PVC, chlorinated paraffin, sodium hypo... Lub brine depleted yuav rov qab brine seem tom qab dichlorination.
3. Qhov zoo ntawm peb lub tuam txhab
Chongqing Biogreen Engineering Thiab Technology Co., Ltd.(tom qab no hu ua CBETC), yog lub tuam txhab kev lag luam ntawm kev tsim, kev yuav khoom, kev teeb tsa thiab kev ua haujlwm ntawm cov nroj tsuag caustic soda. Peb tuaj yeem muab cov neeg siv khoom nrog kev tshaj lij kev daws teeb meem tag nrho.
Raws li peb tus kheej R & D lub zog thiab kev tswj hwm zoo, CBETC koom tes nrog ntau lub tsev kawm ntawv qib siab thiab cov koom haum, txhawb kom sib koom ua ke kev xav nrog kev xyaum, mob siab rau peb tus kheej rau kev txhim kho thiab siv cov tshuab ua kua dej qab zib ntau lawm.
Peb tau cog lus rau ntau lub teb chaws thiab cheeb tsam xws li Kaus Lim Qab Teb, Jordan, Bangladesh, Indonesia, Nyab Laj, Tim lyiv teb chaws, Myanmar, Kazakhstan, thiab Sri Lanka thiab lwm yam.
