Nws kuj yog siv nyob rau hauv kev tsim cov tshuaj, ntawv, xab npum thiab xab npum, rayon thiab cellophane, ua bauxite ua alumina, thiab kuj siv nyob rau hauv mercerizing textiles, dej kho, thiab lwm yam.
Khoom siv
1. Rau papermaking thiab cellulose pulp ntau lawm;
2. Nws yog siv rau hauv kev tsim cov xab npum, cov khoom siv hluavtaws, hluavtaws fatty acids thiab kev ua kom zoo ntawm cov tsiaj thiab zaub roj.
3. Textile printing thiab dyeing kev lag luam yog siv los ua paj rwb desizing tus neeg saib xyuas, scouring tus neeg saib xyuas thiab mercerizing tus neeg saib xyuas.
4. Kev lag luam tshuaj yog siv los tsim borax, oxalic acid, phenol, thiab lwm yam.
5. Kev lag luam roj av yog siv los kho cov khoom siv roj av thiab hauv cov roj av drilling av nkos. Nws kuj tseem siv rau hauv kev tsim cov txhuas oxide, hlau zinc thiab hlau tooj liab nto kho thiab iav, enamel, tanning, tshuaj, dyes thiab tshuaj tua kab.
6. Cov khoom noj khoom haus qib yog siv los ua cov kua qaub nruab nrab hauv kev lag luam khoom noj, cov tshuaj tua kab mob rau citrus, txiv duaj, thiab lwm yam, nrog rau cov tshuaj detergents rau ntim xws li lub raj mis khoob thiab cov kaus poom, nrog rau decolorizers thiab deodorizers.
7. Nws kuj tseem siv tau los ua ib qho alkaline desiccant. Caustic soda yog dav siv nyob rau hauv lub teb chaws kev lag luam, thiab ntau lub lag luam sector xav tau caustic soda. Cov chaw uas siv cov dej qab zib caustic yog cov tshuaj tsim khoom, ua raws li ntawv, txhuas, tungsten, rayon, rayon, thiab xab npum tsim. Nyob rau hauv tas li ntawd, nyob rau hauv zus tau tej cov dyes, plastics, tshuaj thiab organic intermediates, lub regeneration ntawm qub roj hmab, zus tau tej cov sodium hlau, electrolysis ntawm dej thiab zus tau tej cov inorganic ntsev, zus tau tej cov borax, chromium ntsev, manganates, phosphates. , thiab lwm yam, yuav tsum tau siv. Muaj ntau ntau caustic soda.
Kev tiv thaiv tshuaj lom
Nws yog corrosive heev, thiab nws cov tshuaj los yog plua plav splashes ntawm daim tawv nqaij, tshwj xeeb tshaj yog cov mucous daim nyias nyias, uas yuav ua tau mos mos thiab nkag mus rau hauv cov ntaub so ntswg sib sib zog nqus. Hniav tom qab hlawv. Splashed rau hauv lub qhov muag, tsis tsuas yog ua rau lub cornea, tab sis kuj yuav ua rau lub qhov muag sib sib zog nqus cov ntaub so ntswg. Yog hais tias ua txhaum ntawm daim tawv nqaij, yaug nrog dej tam sim ntawd rau 10 feeb; Yog hais tias txaws rau hauv lub qhov muag, tam sim ntawd yaug nrog dej los yog ib txwm saline rau 15 feeb, thiab ces ntxiv 2 feem pua novocaine. Cov mob hnyav yuav tsum raug xa mus rau tsev kho mob tam sim ntawd. Lub siab tso cai siab ntawm caustic soda hmoov av hauv huab cua yog 0.5mg / m3. Cov neeg ua haujlwm yuav tsum hnav khaub ncaws ua haujlwm, qhov ncauj qhov ntswg, tsom iav tiv thaiv, hnab looj tes roj hmab, hnab looj tes roj hmab, khau looj plab ntev thiab lwm yam khoom siv tiv thaiv kev ua haujlwm thaum ua haujlwm. Ib qho tshuaj nruab nrab thiab hydrophobic yuav tsum tau siv rau ntawm daim tawv nqaij. Rhiav ntau lawm yuav tsum tau zoo ventilated.
