Cov xim lim dej kom pom tseeb tsim los ntawm cov lag luam zeb textile muaj kuab paug ntau rau cov ib puag ncig. Yog li, cov dej khib nyiab yuav tsum tau kho ua ntej nws tuaj yeem tawm los yog rov ua dua tshiab. Ozone yog oxidant muaj zog heev thiab ua lub luag haujlwm tseem ceeb hauv kev kho cov dej khib nyiab.
Kev luam ntawv thiab zas xim tsis muaj dej khib nyiab yog cov dej xev pov tseg nrog cov kua dej loj, muaj cov organic siab thiab muaj pes tsawg leeg. Cov dej kuj tseem muaj qhov ntau ntawm cov qias neeg tso tseg, alkalis, diazo, azo, thiab lwm yam, uas nyuaj rau kev daws. Textile dej khib nyiab feem ntau kho tau hauv peb theem:
Ua ntej: kev kho mob lub cev, sib cais los ntawm kev ziab thiab xaim hluav taws xob;
Thib ob: kev siv tshuaj kho mob, ntxiv cov neeg sawv cev rau tshuaj kom txhim kho cov dej kom zoo;
Thib peb: kev kho siab heev, siv cov txheej txheem oov oxidation , zoo txo COD, BOD qhov tseem ceeb, thiab zoo heev txhim kho kev siv dej rov qab siv dua los yog ua raws.
Nws daim ntawv thov ozone:
Ozone yog ib qho muaj zog oxidant, thiab nws lub peev xwm redox hauv dej yog thib ob rau fluorine. Nws yog feem ntau siv rau hauv kev tiv thaiv ua ntej thiab kev kho kom zoo ntawm kev ua dej khib nyiab. Nws muaj ntau txoj haujlwm hauv kev kho dej, kom tsis muaj menyuam, decolorization, deodorization, deodorization thiab oxidative decomposition. Ozone feem ntau yog siv los ua kev tsis zoo thiab ua rau cov teeb meem organic thiab txo COD thiab BOD qhov tseem ceeb hauv kev kho luam ntawv thiab zas xim tsis huv.
Hauv kev cuam tshuam nrog lub chromaticity ntawm luam ntawv thiab dyeing dej khib nyiab, ozone oxidation tuaj yeem ua txhaum qhov sib txawv ntawm cov zas xim los yog chromogenic gene ntawm cov xim, thiab tib lub sijhawm rhuav tshem cov cyclic compound tsim cov chromophore pab pawg, yog li txiav txim siab cov dej tsis huv.
Ozone reacts nrog nyuaj-rau-degrade organic teeb meem, uas hloov pauv kev ua kom tsis muaj kuab paug ntawm cov pa phem thiab biochemically degrades. Tib lub sijhawm, txo cov COD thiab BOD, txuas ntxiv txhim kho cov dej kom zoo. Ozone tuaj yeem oxidize feem ntau cov teeb meem organic thiab kab mob me me hauv cov dej khib nyiab, thiab txo nws cov COD thiab BOD qhov tseem ceeb yam tsis muaj kev ua qias tuaj thiab kev ua kom yooj yim. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txiav txim siab, sterilize thiab deodorize. Nws tau dav siv hauv kev kho tshiab ntawm kev kho cov dej khib nyiab.
