1, Dab tsi yog colorant?
Xim Masterbatch, tseem hu ua colorants, yog ib hom tshiab ntawm cov xim tshwj xeeb rau cov ntaub ntawv polymer, tseem hu ua pigment npaj.
Nws yog tsim los ntawm peb lub hauv paus ntsiab lus: pigments los yog dyes, nqa, thiab additives. Nws yog ib qho aggregate tau los ntawm uniformly txuas ib tug super tas li tus nqi ntawm cov xim los yog dyes rau ib resin, uas yuav hu ua pigment concentration. Yog li ntawd, nws lub zog xim yog siab dua li cov xim nws tus kheej.
Nyob rau hauv luv luv, ib tug colorant yog ib tug aggregate ua los ntawm uniformly txuas ib tug super tas li pigment los yog dye rau ib resin.
2, Dab tsi yog cov yam ntxwv ntawm cov xim?
Lub hauv paus ntsiab lus ntawm colorants yog:
1. Pigments lossis dyes
Pigments tau muab faib ua cov organic pigments thiab inorganic pigments.
Cov organic pigments muaj xws li phthalocyanine liab, phthalocyanine xiav, phthalocyanine ntsuab, hnub resistant kaj liab, macromolecular liab, macromolecular daj, perpetual daj, perpetual ntshav, azo liab, thiab lwm yam.
Cov xim tsis muaj xim muaj xws li cadmium liab, cadmium daj, titanium dioxide, carbon dub, hlau oxide liab, hlau oxide daj, thiab lwm yam.
2. Cov Cab Khoom
Cov cab kuj yog cov matrix ntawm cov xim masterbatch. Cov xim tshwj xeeb feem ntau xaiv cov khoom siv tib yam li cov khoom siv ua cov khoom thauj, uas muaj qhov zoo tshaj plaws kev sib raug zoo ntawm ob, tab sis tib lub sij hawm, qhov flowability ntawm cov cab kuj yuav tsum tau txiav txim siab.
3. Dispersant
Txhawm rau txhawb kev sib cais ntawm cov xim thiab tiv thaiv agglomeration, lub melting point ntawm dispersants yuav tsum qis dua li cov resins, muaj zoo compatibility nrog resins, thiab muaj affinity zoo nrog pigments. Feem ntau siv dispersants yog polyethylene low molecular wax thiab stearic acid ntsev.
4. Cov tshuaj ntxiv
Ntau yam xws li nplaim retardant, brightening, antibacterial, anti-static, antioxidant, thiab lwm yam yog feem ntau tsis suav nrog cov xim masterbatch tshwj tsis yog thov los ntawm cov neeg siv khoom.
3, Dab tsi yog hom thiab qib ntawm colorants?
Feem ntau siv cov kev faib cov xim rau cov xim yog raws li nram no:
Muab faib los ntawm cov cab kuj: xws li PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, thiab lwm yam;
Muab faib los ntawm lub hom phiaj: xws li tshuaj pleev xim, tshuab moulding colorants, spinning colorants, thiab lwm yam.
Txhua yam tuaj yeem muab faib ua qib sib txawv, xws li:
1. Cov tshuaj pleev xim zoo tshaj plaws: siv rau cov thawv ntim khoom kom zoo nkauj, cov khoom ua si, cov khoom siv hluav taws xob, thiab lwm yam khoom siv high-end.
2. Ordinary txhaj tshuaj xim: siv rau cov khoom yas niaj hnub, cov thawv ntim khoom, thiab lwm yam.
3. Advanced blown film colorant: siv rau tshuab moulding coloring ntawm ultra-nyias cov khoom.
4. Ordinary blown film colorant: siv rau tshuab moulding coloring ntawm lub hnab ntim dav dav thiab cov hnab woven.
5. Spinning colorants: siv rau coloring textile fibers thaum spinning. Cov xim muaj cov xim zoo nkauj, siab concentration, muaj zog xim muaj zog, thiab zoo cua sov thiab lub teeb.
6. Tsawg qib xim masterbatch: siv los tsim cov khoom lag luam qib qis uas tsis tas yuav tsum muaj xim zoo, xws li cov thoob khib nyiab, ntim qis, thiab lwm yam.
7. Tshwj xeeb xim masterbatch:
Nws yog xim masterbatch tsim siv tib lub yas raws li cov cab kuj raws li cov yas ntau yam teev los ntawm tus neeg siv rau cov khoom. Piv txwv li, PP masterbatch thiab ABS masterbatch feem ntau yog siv los ua cov nqa khoom.
8. Universal colorant: Nws kuj siv ib co resin (feem ntau tsis tshua muaj melting point PE) raws li ib tug cab kuj, tab sis nws yuav siv tau rau coloring lwm resins dua li nws cov cab kuj resin.
Universal colorants yog qhov yooj yim thiab yooj yim, tab sis lawv muaj ntau yam tsis zoo. Cov qib kub tsis kam ntawm cov xim tshwj xeeb yog feem ntau haum rau cov yas siv hauv cov khoom, thiab tuaj yeem siv nrog kev ntseeg siab ntawm qhov kub thiab txias. Tsuas yog nyob rau hauv cov xwm txheej hauv qab no tuaj yeem ua rau muaj qhov sib txawv ntawm cov xim: ib qho yog thaum qhov kub siab tshaj qhov qub, thiab lwm qhov yog thaum lub sijhawm kaw ntev dhau.
9. Piv nrog granulation coloring, masterbatch coloring muaj cov nram qab no zoo:
9.1 Xim thiab cov khoom ua tiav tuaj yeem ua tiav hauv ib qho, zam cov txheej txheem cua sov ntawm granulation xim ntawm cov yas, uas yog qhov zoo rau kev tiv thaiv cov khoom yas zoo.
9.2 Yooj yim rau kev tsim cov khoom yas.
9.3 tuaj yeem txuag hluav taws xob ntau.
4, Vim li cas siv cov xim pleev xim?
Kev siv cov tshuaj pleev xim muaj qhov zoo hauv qab no:
1. Txhim kho qhov dispersibility ntawm pigments hauv cov khoom
Masterbatch yog ib qho kev sib sau ua ke los ntawm kev sib koom ua ke ntawm cov xim tsis tu ncua mus rau ib qho resin.
Thaum lub sij hawm tsim cov txheej txheem ntawm cov xim, nws yog ib qho tsim nyog yuav tsum ua kom zoo dua cov pigments los txhim kho lawv cov dispersibility thiab xim zog. Cov cab kuj ntawm cov xim tshwj xeeb masterbatch yog tib yam li cov yas ntau yam ntawm cov khoom, nrog rau kev sib raug zoo. Tom qab cua sov thiab yaj, cov xim xim tuaj yeem ua kom zoo dispersed hauv cov yas ntawm cov khoom.
2. Muaj txiaj ntsig zoo rau kev tswj cov tshuaj lom neeg ruaj khov ntawm cov pigments
Yog tias cov pigments siv ncaj qha, lawv yuav nqus dej thiab oxidize vim kev sib cuag ncaj qha nrog huab cua thaum khaws cia thiab siv. Txawm li cas los xij, tom qab siv los ua cov xim xim, cov cab kuj tuaj yeem cais cov pigments los ntawm huab cua thiab noo noo, uas tuaj yeem tswj tau lawv qhov zoo rau lub sijhawm ntev.
3. Xyuas kom ruaj khov ntawm cov khoom xim
Xim masterbatch hais zoo ib yam li resin hais, ua rau kev ntsuas yooj yim dua thiab raug. Thaum sib tov, lawv tsis ua raws li lub thawv thiab sib tov sib npaug nrog cov resin. Yog li ntawd, kev ruaj ntseg ntawm cov nyiaj ntxiv tuaj yeem ua kom ntseeg tau, yog li ua kom muaj kev ruaj ntseg ntawm cov khoom xim.
4. Tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm
Pigments feem ntau yog nyob rau hauv hmoov daim ntawv thiab yog nquag ya thaum ntxiv thiab sib tov. Kev nqus tau los ntawm tib neeg lub cev tuaj yeem cuam tshuam kev noj qab haus huv ntawm cov neeg ua haujlwm.
5. Khaws ib puag ncig kom huv si thiab tsis txhob kis cov tais diav
6. Cov txheej txheem yooj yim, hloov xim yooj yim, txuag lub sijhawm thiab cov khoom siv raw
Vim yog kev sib cuag ncaj qha ntawm cov pigments nrog huab cua thaum lub sij hawm cia thiab siv, phenomena xws li noo noo nqus, oxidation, thiab agglomeration yuav tshwm sim. Kev siv ncaj qha tuaj yeem ua rau cov xim me me ntawm cov khoom yas, ua rau cov xim tsaus thiab fading, thiab ua rau cov plua plav ya thaum sib tov, cuam tshuam rau kev noj qab haus huv ntawm cov neeg ua haujlwm.
Thaum lub sij hawm tsim cov txheej txheem, cov xim masterbatch undergoes mechanical processing los refine cov pigments. Cov pigments yog sib xyaw kom huv si nrog cov cab cab thiab cov dispersants kom cais lawv ntawm huab cua thiab noo noo, yog li txhim kho lawv cov huab cua tiv thaiv, txhim kho lawv cov dispersibility thiab xim zog, thiab ua rau cov xim ci. Vim qhov zoo sib xws ntawm cov xim masterbatch thiab resin particles, nws yooj yim dua thiab raug nyob rau hauv kev ntsuas, thiab yuav tsis ua raws li lub thawv thaum sib tov, yog li txuag lub sij hawm rau tu lub thawv thiab tshuab, nrog rau cov ntaub ntawv raw siv los ntxuav cov cav tov.
