Formaldehyde-dawb kho tus neeg saib xyuas HS-2

1. Lub cev thiab tshuaj muaj zog
Colorless los yog yellowish pob tshab kua
Ionic cation
PH 4-6 (1% aqueous tov)
Solubility Yooj yim soluble hauv dej
2. Cov khoom siv tshuaj
1. Ib qho zoo tshaj plaws tom qab dyeing kho tus neeg saib xyuas, uas feem ntau yog siv rau ntau yam txheej txheem los txhim kho cov ntub dej nrawm ntawm cov dyes reactive thiab ncaj dyes ntawm cellulose fibers.
2. Nws tuaj yeem siv nrog cov khoom tsis-ionic thiab cationic.
3. Flocculation thiab sedimentation yuav tshwm sim tib lub sijhawm nrog cov khoom anionic.
3. Kev siv ntau npaum
Nws yog ib qho tsim nyog sau cia tias cov xim kho tus neeg sawv cev HS-2 tsis tuaj yeem sib haum nrog cov khoom anionic, yog li nws tsuas yog siv tau rau cov txheej txheem kho tom qab cov ntaub tag nrho ntxuav.
1. Txoj kev immersion:
Cov ntaub yog kho nrog cov nram qab no fixative HS-2 concentration rau 20 feeb ntawm 25-30 ℃ thiab PH-5.0.0.5-1.5% rau lub teeb rau nruab nrab xim;
1.5-2.5% rau cov xim tsaus.Tom qab ntawd ntxuav nws nrog dej thiab qhuav nws.
2. Dip dov txoj kev:
Raus cov ntaub hauv HS-2 tov ntawm 20-30 ℃, thiab ces yob nws.Kev daws teeb meem ntawm kev kho tus neeg sawv cev HS-2.
7-15 g / L rau lub teeb rau nruab nrab xim;15-30 g / L yog haum rau cov xim tsaus.
Cov ntaub yog qhuav tom qab dipped nyob rau hauv HS-2 tov.
Kev kho tus neeg sawv cev HS-2 tuaj yeem siv los txhim kho qhov ntub nrawm ntawm cov xim ncaj qha.Nws qhov zoo yog tias nws tsis muaj formaldehyde thiab muaj kev cuam tshuam me ntsis ntawm lub teeb xim thiab lub teeb nrawm.
4. stripping
Nws tuaj yeem siv los tev tus neeg saib xyuas kho HS-2 los ntawm cov ntaub nrog cov xim ruaj khov los ntawm cov txheej txheem hauv qab no;
2.0 g / L formic acid yog kho ntawm 90 ℃ rau 20 feeb, thiab tom qab ntawd ntxuav kom huv nrog dej sov.
Ntxiv 1-4 g / L JFC tib lub sijhawm los txhim kho cov nyhuv stripping.
5. Ntim thiab khaws cia
125kg yas nruas, txias thiab qhuav qhov chaw, cia lub sij hawm ntawm ib xyoos.
