Cov xim zas yog cov organic sib xyaw uas muaj xim uas tuaj yeem zas cov fibers lossis lwm cov substrates rau hauv ib qho xim. Lawv feem ntau yog siv rau hauv kev zas luam ntawv ntawm cov xov paj thiab cov ntaub, zas tawv, zas ntawv, cov khoom noj khoom haus ntxiv thiab cov xim yas. Raws li lawv cov khoom thiab cov txheej txheem siv, cov xim zas tuaj yeem muab faib ua cov xim zas disperse, cov xim zas reactive, cov xim zas sulfide, cov xim zas VAT, cov xim zas acid, cov xim zas ncaj qha thiab lwm pawg.
Lub lag luam loj hauv keeb kwm feem ntau yog cuam tshuam nrog tus nqi zas xim, thiab tus nqi zas xim feem ntau nce thiab poob nrog tus nqi khoom siv raw nrog rau kev sib raug zoo ntawm kev muab khoom thiab kev thov txiav txim siab, muaj lub caij nyoog muaj zog tsis muaj zog.

Kev lag luam sab saud ntawm kev lag luam tsim cov xim yog kev lag luam petrochemical, kev lag luam tshuaj lom neeg yooj yim thiab kev lag luam tshuaj lom neeg thee. Cov khoom siv tseem ceeb ntawm cov xim yog benzene, naphthalene, anthracene, heterocycles thiab inorganic acid thiab alkali thiab lwm yam khoom siv tshuaj lom neeg. Kev lag luam sab saud yog kev lag luam luam ntawv thiab zas xim hauv kev lag luam textile.

Cov xim nruab nrab tuaj yeem muab faib ua benzene series, naphthalene series thiab anthracene series raws li lawv cov qauv, ntawm cov benzene series intermediates yog siv dav. Ntawm cov benzene intermediates, m-phenylenediamine thiab reductants yog cov khoom siv tseem ceeb rau kev tsim cov xim disperse, thiab para-ester yog cov intermediates tseem ceeb ntawm cov xim reactive. Ntawm lawv, m-phenylenediamine kuj tseem tuaj yeem tsim ntxiv rau hauv m-phenylenediamine (feem ntau yog siv ua binder rau cov log tsheb impregnation) thiab m-aminophenol (xim kub / siab rhiab heev

cov khoom siv nruab nrab). Cov khoom siv nruab nrab Naphthalene, suav nrog H acids, yog cov khoom siv tseem ceeb rau kev tsim cov xim reactive, suav txog 30-50% ntawm tag nrho cov nqi. Tsis tas li ntawd, cov khoom siv nruab nrab rau kev tsim cov xim anthraquinone feem ntau yog 1-amino-anthraquinone, uas yog los ntawm lub kaw lus anthraquinone.

Kev tshuaj xyuas tsib lub zog ntawm Porter ntawm kev lag luam zas xim 1. Lub zog sib tham ntawm cov neeg muag khoom sab saud tsis muaj zog. Cov neeg muag khoom sab saud ntawm kev lag luam zas xim yog benzene, naphthalene thiab lwm yam khoom siv roj av thiab petrochemical. Kev thov ntawm kev lag luam zas xim rau cov khoom siv roj av thiab petrochemical yog yuav luag tsis muaj dab tsi piv rau lwm yam kev lag luam. Yog li ntawd, kev lag luam zas xim yog tus tau txais tus nqi ntawm cov khoom siv roj av thiab petrochemical sab saud.

2. Muaj zog sib tham rau cov neeg siv khoom tom qab. Cov neeg siv khoom tom qab ntawm kev lag luam zas xim feem ntau yog cov lag luam luam ntawv thiab zas xim. Lub zog sib tham ntawm kev lag luam zas xim rau cov neeg siv khoom tom qab yog vim ob qho laj thawj. Ua ntej, qhov kev sib sau ua ke ntawm kev lag luam zas xim tsawg heev. Qhov thib ob, tus nqi luam ntawv thiab zas xim zas xim me me, cov lag luam luam ntawv thiab zas xim rau cov nqi zas xim nce siab yooj yim lees txais.

3. Muaj tsawg tus neeg nkag mus rau hauv kev lag luam. Vim yog cov thev naus laus zis patent, cov khoom siv raw tseem ceeb thiab cov yam ntxwv tiv thaiv ib puag ncig, kev lag luam dyestuff muaj cov teeb meem loj, thiab kev nthuav dav ntawm lub peev xwm tsim khoom raug txwv. Nyob rau hauv xyoo tas los no, lub peev xwm tsim khoom me me rov qab tau raug tshem tawm thaum ob peb tus neeg nkag tshiab tau nkag mus. Yog li ntawd, yav tom ntej kev lag luam zas xim siab qauv yuav muaj peev xwm txuas ntxiv mus.

4. Cov khoom hloov pauv tsis muaj kev hem thawj ntau. Cov tuam txhab xim txawv teb chaws uas muag cov khoom lag luam zoo lossis cov xim tshwj xeeb tsis muaj kev hem thawj rau kev lag luam xim hauv tsev. Tsis tas li ntawd xwb, vim muaj kev cuam tshuam los ntawm cov se thiab kev thauj khoom, cov nqi ntshuam khoom kuj kim heev. Yog li ntawd, cov khoom hloov pauv tsis muaj kev hem thawj ntau.

5. Kev sib tw ua lag luam theem nrab. Tom qab kev koom ua ke loj ntawm kev lag luam txij xyoo 2009 txog 2010, tus lej ntawm cov lag luam tau poob qis mus rau ntau dua 300. Nrog rau kev txhim kho kev lag luam hauv tebchaws, qib kev sib sau ua ke ntawm kev lag luam xim tau zoo dua qub. Lub peev xwm tsim cov xim disperse hauv tsev feem ntau yog nyob hauv Zhejiang Longsheng, Leap Soil Stock thiab Jihua Group, CR3 yog li 70%, lub peev xwm tsim cov xim reactive yog siab dua hauv Zhejiang Longsheng, Leap soil Stock, Hubei Chuyuan, Taixing Caragian thiab Anoki tsib lub tuam txhab, CR3 yog ze li ntawm 50%.
Kev soj ntsuam qhia tau tias kev coj mus rau lub sijhawm ntev ntawm kev ua lag luam khaub ncaws sab nraum lub caij ncaj qha thawb tus nqi ntawm cov xim sib cais. Cov nqi xim dub Disperse ECT300% tau nce 36% hauv ob lub hlis dhau los.

Hais txog kev thov, vim muaj kev cuam tshuam ntawm tus kab mob sib kis, ntau lub tuam txhab lag luam textile xa tawm loj hauv Is Nrias teb tau hloov ntau daim ntawv xaj mus rau kev tsim khoom hauv tsev hauv ob peb lub hlis dhau los vim tsis muaj peev xwm lav qhov kev xa khoom ib txwm vim muaj tus kab mob sib kis. Tsis tas li ntawd, "Double 11" tab tom los txog, cov lag luam e-lag luam hauv kev txiav txim ua ntej, cov khoom lag luam yog qhov tseem ceeb kom yeej kev ua lag luam. Ntxiv rau xyoo no "lub caij ntuj no txias" xav tau, kev lag luam tau hais tias cov lag luam textile tshwj xeeb tshaj yog tam sim no. Kev thov rau cov xim pleev xim sab saud kuj tau nce siab heev.

Hais txog kev muab khoom, qhov xwm txheej hnyav ntawm kev nyab xeeb thiab kev tiv thaiv ib puag ncig hauv Suav teb yuav txuas ntxiv mus ntev rau yav tom ntej vim muaj kev ua qias tuaj ntau los ntawm kev tsim cov xim thiab cov khoom nruab nrab, thiab kev nyab xeeb thiab kev tiv thaiv ib puag ncig uas tsis zoo thiab muaj peev xwm tsim khoom tsis zoo yuav raug tshem tawm maj mam. Guoxin Securities tau hais tias cov tuam txhab tsim cov xim sib cais me me muaj kev tsim khoom tsawg, qhov xwm txheej tam sim no yog qhov zoo rau kev txhim kho cov tuam txhab ua xim.
