Caustic soda, lwm yam hu ua sodium hydroxide, caustic soda los yog caustic, yog paub rau chemists li NaOH. Yuav luag 57 tons ntawm caustic tau noj txhua xyoo hauv ntiaj teb. Nws yog tsis yooj yim sua xav txog tej yam niaj hnub lub neej tsis muaj caustic soda, txij li thaum caustic soda yog tsim nyog rau ntau manufacturing industries.
Kev tsim cov dej qab zib thiab nws ntau yam
Tam sim no, caustic soda yog tsim los ntawm cov txheej txheem electrochemical hauv kev tsim cov tshuaj chlorine thiab hydrogen thiab los ntawm electrolysis ntawm cov tshuaj halite.
Caustic soda yog tsim nyob rau hauv cov khoom thiab ua kua. Cov khoom yog cov khoom scaly dawb, thiab cov kua yog cov xim dawb lossis xim tsis muaj xim.
Caustic soda daim ntawv thov
Lub luag haujlwm tseem ceeb ntawm kev siv sodium hydroxide suav nrog:
- tshuaj lom neeg kev lag luam;
- pulp thiab ntawv kev lag luam;
- chaw tiv thaiv pej xeem;
- tsim khoom ntawm biodiesel;
- ntxuav cov kav dej;
- tsim tshuaj ntxuav thiab tshuaj ntxuav tes;
- khoom noj khoom haus;
- kev lag luam tshuaj.
Caustic soda, kev siv uas yog dav thiab ntau yam, yog siv los ntawm chemists los ua catalyst lossis reagent nyob rau hauv ntau yam tshuaj tiv thaiv rau neutralize acids, rau titration hauv tshuaj ntsuam xyuas, roj refining, rau zus tau tej cov hlau., thiab lwm yam. Cov neeg paub zoo tshuaj tua kab mob chloramine tsim, kuj siv sodium hydroxide.
Caustic soda muaj nyob rau hauv lub neej niaj hnub ntawm peb txhua tus, txawm tias tsis pom tseeb. Cov tshuaj ntxuav tes yog tsim los siv cov dej qab zib caustic, uas kuj pab kom tshem tawm cov blockages hauv cov kav dej.
Kev thauj mus los
Caustic soda yog thauj los ntawm txoj kev, nrog rau dej thiab tsheb ciav hlau. Cov kua dej qab zib yog thauj mus rau hauv cov thawv tshwj xeeb thiab tso tsheb hlau luam, thiab cov khoom siv sodium hydroxide tau ntim rau hauv hnab. Thaum lub sij hawm kev thauj mus los, nws yuav tsum tau khaws cia kom deb ntawm cov dej noo thiab cua sov.
Soda cia
Lub neej txee ntawm sodium hydroxide yog ib xyoos txij li hnub tsim khoom. Cov khoom lag luam tau muab khaws cia rau hauv qhov chaw tsis muaj cua sov kaw, ntim khoom. Cov khoom ua kua yog muab tso rau hauv lub thawv kaw uas tiv taus alkali.
Nco ntsoov tias cov dej qab zib caustic yog corrosive thiab caustic. Nws tau raug xaiv rau chav kawm txaus ntshai thib ob. Thaum ua haujlwm nrog cov tshuaj no, kev saib xyuas tshwj xeeb raug pom zoo. Thaum pib ua hauj lwm nrog cov khoom los yog kua caustic soda, nws yog advisable los npogob lub qhov muag nrog tshuaj txhuam tsom iav. Ob txhais tes yog npog nrog hnab looj tes nrog ib tug rubberized nto los yog roj hmab. Txhawm rau tiv thaiv lub cev, cov khoom siv roj hmab tshwj xeeb lossis cov khaub ncaws uas tsis muaj tshuaj lom neeg uas muaj cov yas raug siv.
Nyob rau tib neeg lub cev
Thaum caustic soda nkag mus rau hauv cov mucous daim nyias nyias thiab daim tawv nqaij, tshuaj kub nyhiab tuaj yeem tshwm sim. Txhawm rau kom tsis txhob kub hnyiab, qhov chaw cuam tshuam raug pom zoo kom ntxuav tam sim hauv qab dej ntws. Yog hais tias caustic sodium tau rau ntawm daim tawv nqaij, ces nws yuav tsum tau kho nrog ib tug qaug zog tov ntawm vinegar.
