Sodium dichloroisocyanurate(Sab ntawv SDIC) yog ib homchlorine tshuaj tua kab mob Feem ntau siv los ua cov tshuaj tua kab mob kom tsis muaj menyuam, nws yog siv dav hauv kev siv tshuaj tua kab mob, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj tua kab mob hauv cov dej phwj tuaj lossis cov dej tso dej. Ntxiv nrog rau kev siv los ua tshuaj tua kab mob hauv kev lag luam deodorant, SDIC kuj tseem siv rau hauv cov ntaub plaub los tiv thaiv kev kho mob thiab tshuaj dawb hauv kev lag luam textile.
Muaj ntau cov nplai ntawm cov ntaub plaub fibers, thiab thaum lub sij hawm ntxuav lossis ziab, cov fibers yuav kaw ua ke los ntawm cov nplais no. Raws li cov nplai tsuas tuaj yeem txav mus rau hauv ib qho kev taw qhia, cov ntaub tau shrunk irreversibly. Qhov no yog vim li cas wool fabrics yuav tsum tau shrink-proof. Muaj ntau ntau hom shrink-proofing, tab sis lub hauv paus ntsiab lus yog tib yam: tshem tawm cov nplai ntawm cov ntaub plaub.
SDICyog ib tug muaj zog oxidizer nyob rau hauv dej thiab nws aqueous tov yuav uniformly tso hypochlorous acid, uas interacts nrog protein molecules nyob rau hauv cov ntaub plaub cuticle txheej, rhuav ib co bonds nyob rau hauv cov ntaub plaub protein molecules. Vim tias cov nplais protruding muaj lub zog ua haujlwm ntau dua, lawv nyiam ua rau SDIC thiab raug tshem tawm. Wool fibers tsis muaj nplai tuaj yeem swb dawb thiab tsis kaw ua ke, yog li cov ntaub tsis shrinks ntau. Tsis tas li ntawd, siv SDIC kev daws teeb meem los kho cov khoom siv ntaub plaub kuj tuaj yeem tiv thaiv adhesion thaum ntxuav ntaub plaub, xws li qhov tshwm sim ntawm "pilling" tshwm sim. Cov ntaub plaub uas tau txais kev kho mob los tiv thaiv shrink qhia yuav luag tsis muaj shrinkage thiab yog tshuab ntxhua thiab pab dyeing. Thiab tam sim no kho cov ntaub plaub muaj lub siab dawb thiab zoo txhais tes (mos, du, elastic) thiab muag muag thiab ci ntsa iab. Cov nyhuv yog hu ua mercerization.
Feem ntau, siv 2% mus rau 3% kev daws teeb meem ntawm SDIC thiab ntxiv lwm cov tshuaj ntxiv rau impregnate wool lossis wool blended fibers thiab fabrics tuaj yeem tiv thaiv pilling thiab felting ntawm ntaub plaub thiab nws cov khoom.
Kev ua haujlwm feem ntau yog ua raws li hauv qab no:
(1) pub cov ntaub plaub strips;
(2) Kev kho chlorination los ntawm kev siv SDIC thiab sulfuric acid;
(3) Kev kho dechlorination: kho nrog sodium metabisulfite;
(4) Kev kho descaling: siv cov tshuaj descaling rau kev kho mob, cov khoom tseem ceeb ntawm cov tshuaj descaling yog dej qab zib tshauv thiab hydrolytic protease;
(5) Kev tu;
(6) Resin kev kho mob: siv cov tshuaj kho resin rau kev kho mob, nyob rau hauv cov tshuaj kho resin yog ib qho kev kho cov tshuaj resin tsim los ntawm cov khoom sib xyaw;
(7) softening thiab ziab.
Cov txheej txheem no yooj yim los tswj, yuav tsis ua rau muaj fiber ntau puas, ua kom lub sijhawm ua haujlwm luv.
Cov kev ua haujlwm li niaj zaus yog:
pH ntawm da dej yog 3.5 txog 5.5;
Lub sijhawm tshuaj tiv thaiv yog 30 mus rau 90 min;
Lwm cov tshuaj tua kab mob chlorine, xws li trichloroisocyanuric acid, sodium hypochlorite tov thiab chlorosulfuric acid, kuj siv tau rau cov ntaub plaub, tab sis:
Trichloroisocyanuric acidmuaj solubility tsawg heev, npaj cov kev ua hauj lwm kev daws teeb meem thiab siv yog heev teeb meem.
Sodium hypochlorite tov yog ib qho yooj yim mus use, tab sis muaj ib tug luv luv txee lub neej. Qhov no txhais tau hais tias yog khaws cia rau ib lub sijhawm, nws cov ntsiab lus chlorine zoo yuav poob qis, ua rau cov nqi nce ntxiv. Rau cov tshuaj sodium hypochlorite uas tau khaws cia rau ib lub sijhawm, cov ntsiab lus chlorine zoo yuav tsum tau ntsuas ua ntej siv, txwv tsis pub cov kev daws teeb meem ntawm qee qhov concentration tsis tuaj yeem npaj tau. Qhov no nce nqi zog. Tsis muaj teeb meem zoo li no thaum muag nws rau kev siv tam sim, tab sis nws txwv nws daim ntawv thov heev.
Chlorosulfonic acid yog heev reactive, txaus ntshai, lom, emission fumes nyob rau hauv cov huab cua, thiab yog tsis yooj yim rau thauj, khaws cia, thiab siv.
