CAS No. 7783-6-4 Hydrogen Sulfide Factory. Cov yam ntxwv ntawm Hydrogen Sulfide
Hydrogen sulfide (H₂S) yog ib qho tshuaj lom, tsis muaj xim tsis muaj roj uas paub txog nws lub zog, foul, rotten qe tsw ntawm qhov tsawg. Ntawm qhov siab dua, txawm li cas los xij, qhov tsis hnov tsw yuav tsis hnov qab vim tias nws tuaj yeem ua rau qhov tsis hnov tsw sai sai. H₂S hnyav dua huab cua thiab yog nplaim taws. Nws feem ntau pom muaj nyob rau hauv ntau qhov kev lag luam thiab cov khoom siv ntuj tsim xws li cov roj hluav taws xob hluav taws xob, cov dej kub, thiab roj av.

Lub cev muaj zog:
Hydrogen sulfide yog ib qho roj ntawm chav tsev kub thiab siab.
Nws yog soluble hauv dej thiab yog ib qho tsis muaj zog acid.
Nws hnyav dua li huab cua, uas txhais tau hais tias nws nyiam nyob rau hauv qhov chaw qis qis.
Toxicity:
Hydrogen sulfide yog tshuaj lom heev, ua rau ua pa tuag tes tuag taw thiab tuaj yeem ua rau tuag taus ntawm qhov siab.
Nws tuaj yeem ua rau qhov muag khaus, mob taub hau, kiv taub hau, thiab nyob rau theem siab, tam sim ntawd tawg thiab tuag.
Kev siv:
Hauv kev ua cov ores uas muaj sulfur.
Hauv kev lag luam pulp thiab ntawv.
Nyob rau hauv zus tau tej cov elemental sulfur thiab sulfuric acid.
Raws li ib tug txo tus neeg sawv cev nyob rau hauv chemical synthesis.
Kev tuav thiab khaws cia:
Hydrogen sulfide yuav tsum tau ua tib zoo saib xyuas vim nws toxicity.
Nws yuav tsum tau muab cia rau hauv qhov chaw zoo-ventilated thiab deb ntawm txhua qhov chaw ntawm qhov hluav taws kub.
Cov cuab yeej tiv thaiv yuav tsum hnav thaum tuav H₂S.
Thaum nrhiav tus neeg muag khoom, nws yog ib qho tseem ceeb los xyuas kom meej tias tag nrho cov kev cai hauv zos thiab thoob ntiaj teb tau ua raws, thiab koj lub chaw muaj kev ntsuas kev nyab xeeb kom zoo los tswj cov roj kom zoo. Nco ntsoov sab laj nrog cov kws paub txog kev noj qab haus huv thiab kev nyab xeeb thaum npaj ua haujlwm nrog hydrogen sulfide lossis lwm yam khoom muaj txiaj ntsig.
Shanghai Wechem Chemical Co., Ltd., raws li ib tug enterprise pab cov neeg muas zaub nyob rau hauv semiconductor manufacturing, tshiab tshuaj tshawb fawb thiab kev loj hlob ntau lawm, aerospace, thiab hnub ci zog industries, peb yeej paub zoo txog lawv cov kev xav tau thiab kev lag luam.
