Yuav ua li cas los daws qhov teeb meem ntawm cov pa phem loj thiab tsis ruaj tsis khov dyeing txheej txheem ntawm sulfur dub dye?

Vim li cas qee lub tuam txhab siv ntau npaum li cassulfur dubTxawm li cas los xij, kev siv cov nyhuv tsis zoo heev.Yuav kom daws tau qhov ua paug hnyav thiab tsis ruaj khov dyeing nyob rau hauv cov txheej txheem ntawm sulfur dub dyeing txheej txheem, cov khoom siv txo D tau siv los ua cov sulfur dub BR txo tus neeg sawv cev rau dye paj rwb yarns, thiab dyeing. Kev ua tau zoo thiab kev huv ntawm cov tshuaj alkali sodium tau muab piv. Cov kev cuam tshuam ntawm huab hwm coj ntau ntawm sulfur dub BR, sodium hydroxide, composite txo tus neeg sawv cev D, thiab dyeing kub ntawm cov khoom dyeing tau txheeb xyuas. Cov txiaj ntsig kev sim qhia tau hais tias nyob rau hauv cov xwm txheej loj ntawm cov sulfur dub BR 60 g / L, sodium hydroxide 20 g / L, composite txo tus neeg sawv cev D 19 g / L, thiab dyeing kub 95 ℃, pom meej xim tob (K / S ) tus nqi ntawm cov xov paj yog 46.88, soaping fastness ncav cuag 4-5, lub qhuav rubbing ceev yog 4 thiab ntub ntub ceev ceev yog 2. Cov sib xyaw txo tus neeg sawv cev D raws li tus neeg sawv cev txo yog piv nrog cov tshuaj sodium sulfide, thiab K /S tus nqi ntawm cov xov paj dyed nrog composite txo tus neeg sawv cev D yog zoo dua li cov txheej txheem alkali sulfide. Qhov txo cov piam thaj hauv cov tshuaj dyeing yog txo los ntawm 78.0%, thiab cov tshuaj oxygen xav tau hauv lub tshuab khib nyiab yog txo los ntawm 76.4%.

Yog li ntawd, txhawm rau txhim kho cov nyhuv dyeing thiab txuag cov nqi hauv kev sivsulfur dubdyeing, peb yuav tsum paub yuav ua li cas siv complex txo cov neeg ua haujlwm, ib puag ncig tus phooj ywg txo cov neeg ua haujlwm thiab kev siv cov txheej txheem tuaj yeem hu tau txhua lub sijhawm los tham, peb tuaj yeem muab cov kev pabcuam zoo dua.

Peb lub tuam txhab tsuas yog tsim Sulfur dub, kua Sulfur dub, Perennial export rau Bangladesh. Is Nrias teb. Pakistan. Egypt, thiab Iran. Ob qhov khoom thiab qhov zoo yog qhov ruaj khov. Qhov tseem ceeb tshaj yog tus nqi kom zoo dua.
