Kev siv Chloramine T hauv kev luam ntawv thiab zas xim:

(1) Ua ib tug neeg sawv cev bleaching: Chloramine T feem ntau yog siv los bleach cov nroj tsuag fibers. Nws yooj yim heev rau kev siv. Tsuas yog ntxiv ib qho dej kom tsim nyog kom yaj nws, tom qab ntawd ntxiv dej kom dilute nws mus rau hauv 0.1-0.3% kua. Tom qab cua sov rau 70-80 ° C, cov ntaub tuaj yeem muab tso rau hauv bleaching. Chloramine T kuj tseem siv tau rau bleaching ntaub xws li rayon. Tsuas yog muab cov khoom bleached rau hauv cov kua saum toj no, cua sov rau 70-80 ° C, thiab tom qab tso nws rau 1-2 teev, coj nws tawm thiab ntxuav nws nrog dej, thiab tom qab ntawd ntxuav nws nrog dilute acetic acid lossis dilute hydrochloric acid kua kom neutralize cov alkalinity seem ntawm cov ntaub.

(2) Ua tus neeg sawv cev oxidative desizing: Thaum cov ntaub paj rwb raug desizing nrog oxidant, ntxiv rau sodium hypochlorite, chloramine T kuj tseem siv tau. Thaum chloramine T reacts nrog dej, hypochlorous acid tsim, thiab tom qab ntawd hypochlorous acid decomposes kom tso cov pa oxygen tshiab. Oxidative desizing yog qhov ceev heev, tab sis yuav tsum tau them sai sai rau kev tswj hwm cov xwm txheej engineering, txwv tsis pub cov fiber yuav puas tsuaj.

Sodium sulfonylchloramine (chloramine T) muaj cov txiaj ntsig ntawm kev txhawb nqa kev sib txawv ntawm tes.
