Kev siv cov dyes ua rau tib neeg lub neej muaj yeeb yuj.

Los ntawm cov khaub ncaws ntawm lub cev, lub tsev kawm ntawv lub hnab nyob rau sab nraub qaum, ua ib txoj phuam qhwv caj dab, khi, feem ntau yog siv rau hauv knitted fabrics, woven fabrics thiab fiber ntau cov khoom, zas lawv nrog xim liab, daj, ntshav thiab xiav.
Nyob rau hauv txoj cai, raws li ib tug organic compound, dye, nyob rau hauv nws cov molecular los yog dispersed lub xeev, muab lwm yam khoom ib tug kaj thiab ruaj xim.

Nyob rau hauv qhov tseeb, disperse dyes yog ib yam uas tsis yog-ionic dyes nrog tsawg dej solubility.

Nws cov qauv molecular yog yooj yim, solubility yog tsawg, nyob rau hauv thiaj li yuav tau disperse zoo nyob rau hauv cov tshuaj, ntxiv rau kev sib tsoo nws tsawg tshaj li 2 microns, kuj yuav tsum tau ntxiv ntau dispersants, thiaj li hais tias nws muaj peev xwm disperse. nyob rau hauv cov tshuaj tsis tu ncua.Yog li ntawd, hom dye no dav hu ua "disperse dye".

Nws tuaj yeem muab faib ua cov txiv kab ntxwv disperse, disperse daj, disperse xiav, disperse liab thiab hais txog, ob peb xim raws li sib txawv proportions, kuj tau ntau xim.Piv nrog rau lwm yam dyes, disperse dyes yog cov feem ntau lug siv thiab ib tug ntawm qhov tseem ceeb tshaj plaws dyes.

Vim yog kev siv ntau ntawm disperse dyes, tus nqi hloov pauv ntawm nws cov khoom siv raw thiab cov khoom tseem cuam tshuam rau kev hloov pauv sai ntawm cov nqi sib koom ntawm cov tuam txhab teev npe.

Thaum Lub Peb Hlis 21, 2019, qhov tawg tau tshwm sim ntawm xiangshui Chenjiagang Tianjiayi Chemical Factory hauv Yancheng. Pawg CPC Central Committee thiab Xeev Pawg Neeg Saib Xyuas tau muab qhov tseem ceeb rau qhov kev tawg. Lub xeev Jiangsu thiab cov tuam haujlwm cuam tshuam tau ua qhov zoo tshaj plaws los cawm thiab cawm tib neeg los ntawm txhua qhov chaw ntawm lub neej thov Vajtswv rau Xiangshui.

Tom qab tawg, cov chaw ua haujlwm tshuaj lom neeg hauv lub tebchaws tau pib ua haujlwm tshuaj xyuas kev nyab xeeb thaum muaj xwm txheej ceev. Shaoxing Shangyu, lub nroog loj dyestuff ntau lawm, kuj tau pib tshawb xyuas kev nyab xeeb thoob plaws hauv cheeb tsam, uas yuav ua rau cov tuam txhab tshuaj lom neeg thoob plaws lub tebchaws kom suab nrov thiab yuav tsum ua haujlwm nyab xeeb.

Cov khoom tseem ceeb ntawm cov nroj tsuag tshuaj muaj xws li disperse dyes thiab lwm yam reactive dyes, ncaj dyes intermediates - m-phenylenediamine.

Tom qab tawg, ntau yam disperse dye tuam txhab thiab cov tuam txhab nruab nrab tau tso tseg tsis lees txais kev txiav txim, ncaj qha ua rau cov khoom lag luam tsis txaus ntawm m-phenylenediamine, uas yog khi rau thawb tus nqi nce siab ntawm downstream disperse dye khoom.

Kev lag luam tus nqi ntawm m-phenylenediamine tau ntau dua ob npaug txij li lub Peb Hlis 24, thiab kev sib xyaw ua ke ntawm qhov tsis txaus ntawm cov khoom lag luam thiab kev cuam tshuam rau lub peev xwm ntau lawm yuav thawb cov tshuaj tua kab mob ntau dua.
Thiab ob peb lub teb chaws disperse dye npe tuam txhab lag luam qhia cov nqi tau nce thiab poob qis, nws tsis yooj yim rau kev nkag siab.Tab sis qhov volatility ntawm disperse dyes tsis yog ib qho kev tshwm sim random nyob rau hauv xyoo tas los no, thiab tib neeg tau ntev paub txog volatility ntawm nws cov nqi Tshuag. .

➤ Los ntawm qhov kev xav ntawm kev sib tw ua lag luam, kev lag luam disperse dye lag luam tau maj mam tsim ib qho kev sib tw ua lag luam oligopoly, thaum qhov kev thov rau cov xim disperse yog qhov ruaj khov. Qhov nce ntawm qhov concentration ntawm disperse dye lag luam yuav cuam tshuam rau cov khoom lag luam thiab kev thov, txhim kho lub zog sib tham ntawm cov neeg muag khoom, thiab tom qab ntawd txhawb tus nqi nce ntawm kev lag luam dyeing.

Hauv xyoo 2018, kev ua haujlwm ntawm cov tuam txhab teev npe nrog cov tshuaj tua kab mob tau zoo dua, thiab hauv 2019, yog tias qhov kev ua tau zoo txuas ntxiv mus, cov khoom lag luam nce siab yog qhov kev ntsuas ncaj qha thiab zoo tshaj plaws.

Ntawm qhov tod tes, vim muaj kev tiv thaiv ib puag ncig ua ntej, qhov no tseem yuav ua rau cov khoom tawg ntawm cov xim zas cov nqi yuav ua rau siab ua haujlwm.Tsis tsuas yog kev tiv thaiv ib puag ncig kev tswj cov nqi nce, xws li kev hloov pauv raws sij hawm ntawm kev txwv ntau lawm yuav cuam tshuam rau cov khoom lag luam disperse dye. .

Txawm hais tias qee lub tuam txhab disperse dye lag luam uas ib zaug tso tseg yuav maj mam rov pib tsim khoom, nws yog qhov ntau dua tias cov khoom tsim tawm ntawm cov lag luam luam tawm deb tsawg dua li ua ntej kev tsim khoom raug tso tseg.

Kev sib ntaus sib tua hnyav tiv thaiv kev ua qias tuaj yuav thawb ntau qhov kev lag luam nrog ntau lub peev xwm los tshem tawm, thiab kev lag luam dyeing tseem muaj txoj hauv kev mus ntev.
