Ib: Dab tsi yog qhov tseem ceeb ntawm cov xim niam?
Lub hauv paus ntawm cov xim niam yog:
1.Pigment lossis zas xim
Pigments kuj tau muab faib ua cov organic pigments thiab inorganic pigments
Feem ntau siv cov organic pigments yog: phthalocyanine liab, phthalocyanine xiav, phthalocyanine ntsuab, hnub-resistant kaj liab, macromolecular liab, macromolecular daj, ruaj khov daj, ruaj khov ntshav, azo liab thiab lwm yam.
Feem ntau siv inorganic pigments yog: cadmium liab, cadmium daj, titanium dioxide, carbon dub, hlau oxide liab, hlau oxide daj thiab hais txog.
2. cab cab
Lub vector yog lub matrix ntawm chromomasterpiece. Cov xim tshwj xeeb feem ntau xaiv cov khoom siv tib yam li cov khoom siv cob raws li cov cab kuj, kev sib raug zoo ntawm ob, tab sis kev txav mus los ntawm cov cab kuj yuav tsum tau txiav txim siab.
3. dispersant
Txhawb cov pigment uniform dispersion thiab tsis condensed lawm, lub melting point ntawm dispersant yuav tsum qis dua li resin, thiab resin muaj ib tug zoo compatibility, thiab cov xim muaj ib tug zoo affinity. Feem ntau siv dispersants yog: polyethylene low molecular wax, stearate.
4. additive
Xws li nplaim retardant, brightening, antibacterial, antistatic, antioxidant thiab lwm yam, tshwj tsis yog cov neeg yuav tsum tau, feem ntau nyob rau hauv cov xim niam tsis muaj cov saum toj no additives.
2: Cov ntau yam thiab qib twg muab faib ua cov xim niam?
Txoj kev faib cov xim niam feem ntau yog siv raws li hauv qab no:
Kev faib tawm los ntawm cov cab kuj: xws li PE xim, PP xim, ABS xim, PVC xim, EVA xim, thiab lwm yam
Kev faib tawm los ntawm kev siv: xws li txhaj tshuaj niam, tshuab yas xim niam, spinning xim niam, thiab lwm yam
Txhua yam tuaj yeem muab faib ua ntau qib, xws li:
1.Advanced txhaj tshuaj ntawm cov xim niam
Rau cov thawv ntim tshuaj pleev ib ce, cov khoom ua si, lub plhaub hluav taws xob thiab lwm yam khoom siv siab heev
2.Ordinary txhaj xim niam
Siv rau cov khoom yas niaj hnub, cov thawv ntim khoom, thiab lwm yam
3.Advanced tshuab zaj duab xis xim niam
Tshuab tshuab thiab cov xim yas siv rau cov khoom siv ultra-nyias.
4.Ordinary tshuab zaj duab xis xim niam
Siv rau cov hnab ntim dav dav, cov hnab woven tshuab tshuab xim xim.
5.Spinning xim niam
Siv rau textile fiber spinning dyeing, xim niam pigment zoo hais, siab concentration, muaj zog xim quab yuam, tshav kub tsis kam, zoo lub teeb.
6. Niam xim
Siv los tsim cov khoom lag luam uas tsis tshua muaj xim tsis zoo, xws li cov thoob khib nyiab, cov thawv ntim qis, thiab lwm yam.
7.Txiv xim niam
Raws li cov yas ntau yam tau teev tseg los ntawm tus neeg siv, tib cov yas raug xaiv raws li tus neeg nqa khoom. Piv txwv li, PP xim niam thiab ABS xim niam feem xaiv PP thiab ABS ua tus nqa khoom.
Cov xim dav dav: kuj tseem siv tau qee yam resin (feem ntau PE nrog cov ntsiab lus melting tsawg) ua cov cab kuj, tab sis nws tuaj yeem tsim nyog rau cov xim ntawm lwm yam uas tsis yog nws cov cab kuj.
8.Ntau xim niam
Cov xim dav yog qhov yooj yim thiab yooj yim, tab sis muaj ntau qhov tsis zoo, nws pom zoo kom cov neeg siv xaiv xim tshwj xeeb yog.
Cov qib kub tsis kam ntawm cov niam xim tshwj xeeb yog feem ntau yoog rau cov yas siv hauv cov khoom, thiab tuaj yeem siv rau qhov kub thiab txias. Tsuas yog nyob rau hauv cov xwm txheej hauv qab no yuav ua rau muaj qhov sib txawv ntawm cov xim tsis sib xws, ib qho yog qhov kub thiab txias tshaj qhov qub, ib qho yog lub sijhawm downtime ntev dhau.
9. Master xim xim muaj qhov zoo hauv qab no piv nrog granulation coloring
9.1 Xim thiab cov khoom ua tiav tiav ib zaug, zam cov txheej txheem cua sov ntawm granand xim, uas yog qhov zoo rau kev tiv thaiv cov khoom yas zoo.
9.2 Ua cov txheej txheem tsim khoom ntawm cov khoom yas kom yooj yim tshaj plaws
9.3 Nws tuaj yeem txuag hluav taws xob ntau
3: Vim li cas thiaj siv cov xim niam
Siv cov xim niam muaj qhov zoo hauv qab no:
1.Ua kom cov xim nyob rau hauv cov khoom muaj ib tug zoo dispersion
Tus tswv yog cov aggregate tsim los ntawm nqa cov xim txawv txawv rau cov resin
Hauv cov txheej txheem tsim khoom, cov xim yuav tsum tau ua kom zoo dua los txhim kho cov dispersion thiab xim quab yuam ntawm cov xim. Cov neeg nqa khoom ntawm niam xim tshwj xeeb yog tib yam li cov yas ntau yam ntawm cov khoom, uas muaj peev xwm sib txuam zoo. Tom qab cua sov thiab yaj, cov xim xim tuaj yeem ua kom zoo nyob hauv cov khoom yas.
2.Txhim kho cov tshuaj stability ntawm cov xim
Hauv kev siv cov xim ncaj qha, vim tias cov xim ncaj qha hu rau huab cua hauv cov txheej txheem ntawm kev khaws cia thiab siv, cov xim yuav tshwm sim dej nqus, oxidation thiab lwm yam tshwm sim, thiab tom qab ua cov xim niam, vim tias cov cab kuj yuav pigment thiab huab cua, kev sib cais dej, tuaj yeem ua rau qhov zoo ntawm cov xim tsis hloov mus ntev.
3.Ua kom ruaj ntseg ntawm cov khoom xim
Cov xim master particle zoo ib yam li cov resin particle, uas yooj yim dua thiab raug rau kev ntsuas. Thaum sib tov, nws yuav tsis ua raws li lub thawv, thiab cov khoom sib xyaw nrog cov khoom sib xyaw ua ke ntau dua, yog li nws tuaj yeem ua kom ruaj khov ntawm cov nyiaj ntxiv, thiaj li ua kom ruaj khov ntawm cov xim ntawm cov khoom.
4. Tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm:
Pigments feem ntau yog hmoov, uas yooj yim ya thaum ntxiv thiab sib xyaw, thiab yuav cuam tshuam rau kev noj qab haus huv ntawm cov neeg ua haujlwm tom qab nqus pa.
5.Ua kom ib puag ncig huv si yam tsis muaj kab mob:
6. Cov txheej txheem yooj yim, yooj yim hloov xim, txuag lub sijhawm thiab cov khoom siv raw
Vim tias cov xim ncaj qha hu rau huab cua hauv cov txheej txheem khaws cia thiab siv, noo noo nqus, oxidation, agglomeration thiab lwm yam tshwm sim yuav tshwm sim, kev siv ncaj qha yuav tshwm sim rau saum npoo ntawm cov khoom yas, xim yog tsaus, xim yog yooj yim rau ploj, thiab ua rau cov plua plav thaum sib tov, cuam tshuam rau kev noj qab haus huv ntawm cov neeg ua haujlwm. Thiab cov xim niam particle nyob rau hauv cov txheej txheem ntawm kev ua txhua yam, cov xim tau ua kom zoo dua qub, cov xim thiab cov khoom siv resin, dispersant siab sib xyaw, kom cov xim thiab huab cua, dej cais tawm, txhawm rau txhim kho huab cua tsis kam ntawm cov xim, txhim kho. lub dispersion ntawm cov xim thiab xim quab yuam, xim theem ci. Vim hais tias cov xim niam particle zoo ib yam li cov duab ntawm cov resin particle, nws yooj yim dua thiab raug nyob rau hauv kev ntsuas, thiab yuav tsis ua raws li lub thawv thaum sib tov, yog li nws txuag lub sij hawm ntawm tu lub thawv thiab lub tshuab thiab cov ntaub ntawv raw. siv nyob rau hauv lub tshuab ntxuav.
