Yuav Ua Li Cas Tiv Thaiv Cov Tshuaj Sulfur Dub Tender Ntawm Paj Rwb Fiber?

Cov xim sulfur feem ntau yog siv rau kev zas xim paj rwb, thiab rau cov ntaub paj rwb/vinyl sib xyaw. Nws yaj hauv sodium sulfide thiab yog qhov kev xaiv zoo tshaj plaws rau cov khoom tsaus ntawm cov cellulose fibers, tshwj xeeb tshaj yog rau Sulphur Black 240% thiab Sulphur Blue 7 dyeing. Tus niam txiv ntawm cov xim sulfur tsis muaj kev sib raug zoo rau cov fibers, thiab nws cov qauv muaj cov sulfur bonds (-S-), disulfide bonds (-SS) lossis polysulfide bonds (-Sx-), uas raug txo kom sulfhydryl pawg (-SNa) nyob rau hauv qhov kev ua ntawm sodium sulfide reductant. Ua ib qho dej-soluble leuco sodium ntsev. Leuco muaj kev sib raug zoo rau cov cellulose fibers vim yog cov molecules loj ntawm cov xim, uas tsim cov Van der Waals loj thiab hydrogen bonding forces nrog cov fibers. Txawm hais tias cov xim ntawm cov xim sulfur tsis tiav, feem ntau yog xiav thiab dub, xim tsis ci, tab sis nws cov khoom tsim tau yooj yim, tus nqi qis, cov txheej txheem dyeing yooj yim, kev sib phim xim yooj yim, thiab cov xim ceev ceev zoo. Txawm li cas los xij, yuav tsum nco ntsoov tias qee cov xim sulfur, xws li sulfur dub, yuav ua rau cov paj rwb fiber mos.

Qhov kev sib tw ntawm cov fiber yuav tsum tau them sai sai tom qab lubSulfur Dub 240%Cov xim siv rau kev zas xim. Qee yam yuav ua rau muaj kev pheej hmoo ntawm cov fiber brittleness, xws li kev siv cov xim ntau dhau, uas tsis yog tsuas yog ua rau muaj kev pheej hmoo ntawm brittleness, tab sis kuj txo qhov xim ceev thiab ua rau kev ntxuav nyuaj dua. Tsis tas li ntawd, tom qab zas xim, nws yuav tsum tau ntxuav tag nrho kom tiv thaiv kev ntxuav tsis huv, thiab cov xim ntab ntawm cov xov paj yooj yim rau decompose rau hauv sulfuric acid thaum khaws cia, uas ua rau cov fiber brittle.

Yuav kom txo lossis tiv thaiv kev mob ntawm cov fiber, cov kev ntsuas hauv qab no tuaj yeem ua tau:

1. Txwv cov tshuaj zas dub sulfur: cov tshuaj zas xim tshwj xeeb mercerizing yuav tsum tsis pub tshaj 700 G / pob.

2. Tom qab zas xim lawm, ntxuav kom huv si nrog dej kom tiv thaiv cov xim uas ntab tsis lwj mus ua sulfur acid thaum lub sijhawm khaws cia.

3. Siv cov tshuaj kho mob uas tiv thaiv kev mob, xws li urea, soda ash, sodium acetate, thiab lwm yam.

4. Qhov degree ntawm kev sib tw ntawm cov xov paj uas tau ntxuav dej tsawg dua li ntawm cov xov paj uas tau ntxuav alkali.

5. Qhuav cov xov paj dyed raws sijhawm kom tsis txhob muaj cua sov ntawm cov xov paj ntub hauv cov txheej txheem stacking, ua rau cov ntsiab lus tiv thaiv kev tawg thiab pH txo qis.
