Nyob rau hauv lub xyoo dhau los, Precise tau koom nrog hauv kev tshawb fawb thiab tsim cov xim xim, suav nrogorganic pigments, kuab tshuaj dyes, masterbatchthiabpigment npaj. Kev huv thiab yooj yim-rau-siv yog ib txwm cov neeg siv kev cia siab hauv kev lag luam no. Nrog rau kev nce qib ntawm kev tiv thaiv ib puag ncig thoob ntiaj teb, nrog rau ntau thiab ntau cov tub ntxhais hluas cov kev xav tau rau ib puag ncig kev ua haujlwm zoo, peb tuaj yeem kwv yees tias cov neeg tsim khoom txaus siab siv cov xim zoo nkauj ib puag ncig yuav nce ntxiv. Peb lub tuam txhab kuj muab tso rau pem hauv ntej lub hom phiaj lub tswv yim, uas yog muab xws li huv si thiab yooj yim rau siv colorant, thiaj li mus siv zog rau thawj txoj hauj lwm ntawm Suav.pigment npajneeg tsim khoom. Nyob rau tib lub sijhawm, peb xav rov kho cov duab ntawm "Made in China".
Raws li peb paub, Tuam Tshoj yog ib lub teb chaws loj tshaj plaws ntawm pigments thiab dyes. Tag nrho cov txiaj ntsig txhua xyoo ntawm Tuam Tshoj cov xim pigments yog kwv yees li 170,000 txog 190,000 tons, suav txog li 45% ntawm lub ntiaj teb pigment ntau lawm. Ntxiv mus, Tuam Tshoj kuj tseem muaj peev xwm tshiab tuaj nyob rau hauv 3-5 xyoo tom ntej, uas yuav ncav cuag 280,000 txog 290,000 tons raws li ib xyoos twg. Hais txog xim masterbatch hauv Suav teb, qhov ntawd tseem nce nrog kev loj hlob txhua xyoo txog 12%. Tam sim no lub peev xwm txhua xyoo ntawm cov xim masterbatch hauv Suav teb yog tshaj 1.7 lab tons. Txawm li cas los xij, nws tu siab heev uas Tuam Tshoj cov xim masterbatch tsis nyob hauv kev sib koom ua lag luam hauv kev lag luam xa tawm, vim tias cov tuam txhab masterbatch tsis tshua tawm mus txawm tias qee qhov ntawm lawv muaj peev xwm ntau lawm. Ob tus nqi thiab qhov zoo ntawm lawv cov masterbatch txwv.
Raws li kev siv kev lig kev cai thiab tus nqi, peb paub tias feem ntau ntawm covmasterbatchmanufacturers tseem siv cov hmoov pigments, yog li dab tsi yog qhov zoo thiab qhov tsis xws ntawmhmoov pigments? Peb tuaj yeem pom hauv daim duab hauv qab no.

Rau daim ntawv thov uas xav tau siab dispersion, nws yog ib qhov tsim nyog yuav tau pre-disperse cov hmoov pigment ua ntej, piv txwv li, 'squeezing dej theem' yog lub npe hu ua ib qho ntawm cov tsoos pre-disperse paths ntawm organic pigment. Siv cov txheej txheem no, manufacturers pib los ntawm cov xim lim ncuav mog qab zib theem, ua raws li kev sib tsoo, theem hloov dua siab tshiab, kev kho hnyav, ziab thiab cov txheej txheem ua kom tiav cov txheej txheem ua ntej dispersion. Polyolefin cov khoom siv xws li Polyethylene wax yog siv los ua tus neeg sawv cev dispersing, yog li lub sijhawm sib tsoo pob kuj ntev heev. Tab sis qhov tseem ceeb yog ntxiv tus neeg sawv cev fluidization hauv cov txheej txheem ntawm kev hloov hluav taws xob. Cov khoom sib txawv yuav tsum tau ntxiv tus neeg sawv cev fluidization raws li lawv cov qauv tshuaj. Piv txwv li, ob chav azo pigment yuav tsum tau siv quaternary ammonium ntsev los yog hlau (txhuas ntsev) thiab Salt Lake-pigments siv rau acetyl amino benzene sulfuric acid, sodium hydroxide, thiab lwm yam. Kuj kho pH thiab do txhua lub sijhawm. Cov txheej txheem yog cumbersome, thiab cov zis tau cuam tshuam loj heev. Rau cov tuam txhab tsim khoom, qhov no yog qhov tuag taus, yuav cuam tshuam rau lub sijhawm ntawm kev xa khoom thiab cov khoom lag luam nce qib thiab nthuav dav.
Cov duab ntawm Preperse series
Raws li lwm txoj kev ntawm powdery pigment, pigment npaj muaj qhov zoo. Nws cov dispersibility siab thiab cov yam ntxwv tsis muaj plua plav ua tau raws li cov qauv ntawm cov tshuab tsim khoom & kev tiv thaiv ib puag ncig rau cov lag luam niaj hnub.
Txawm li cas los, cov tsoospigmentkev npajtsis tau muaj kev vam meej hauv lub xyoo dhau los. Dab tsi yog vim li cas rau qhov kev tsis txaus siab no?
Thawj yog vim li cas, txawm tias cov tsoospigment npajtxhim kho lub peev xwm ntawm dispersibility, tus nqi siab tab sis tsis zoo nqi-kev ua tau zoo. Tsis tas li ntawd, muaj ntau tshaj 50% dispersing tus neeg sawv cev (piv txwv li, siv quav ciab) hauv cov tsoospigment npaj, uas txhais tau hais tias lawv daim ntawv thov nyob rau hauv cov kev cai hnyav yog txwv. Ntxiv mus, qee cov khoom raug txwv los ntawm lawv cov cim caj ces, yog li lawv lub peev xwm ntawm dispersibility tau txhim kho me ntsis thiab kev ua yeeb yam ntawm cov xim tsis tshua txaus siab.
Nrog qhov tshwm sim ntawm'Preperse' seriespigment npajslos ntawm PNM, peb nrhiav ib txoj hauv kev los daws peb qhov teeb meem saum toj no. Muaj ntau dua 70% cov ntsiab lus pigment hauv tag nrho'Preperse' series. Tsis tas li ntawd, lub'Preperse-S'series muaj ntau zoo dispersibility uas launched rau polypropylene, polyester, nylon thiab lwm yam tshwj xeeb daim ntaub ntawv.
Kev txhim kho cov ntsiab lus pigment txhais tau hais tias qhov nce ntawm cov khoom siv tau zoo, thiab qhov feem pua ntawm cov dispersants xws li siv quav ciab hauv cov khoom raug txo qis. Nrog rau cov khoom muaj txiaj ntsig zoo dua sab hauv, peb tus nqi yog ze rau cov xim pigment. Yog li ntawd, tus nqi yog pob tshab thiab ua rau lub ntsiab tsis zoo rau peb cov nqi ua.
Meanwhile, tsawg siv quav ciab txhais tau tias tsawg dua tsiv teb tsaws thiab txo qis dua ntawm cov qauv & cov cuab yeej cuab tam hloov. Hauv lwm lo lus, peb cov 'Preperse' series txhim kho cov dispersibility nrog tsawg tus nqi.
Raws li peb paub, dispersibility zoo dua coj cov txiaj ntsig ntau dua, zoo li pom cov txiaj ntsig zoo nrog kev ci ntsa iab zoo dua, lub zog muaj zog thiab lwm yam. Cov neeg siv tuaj yeem tau txais txiaj ntsig ntxiv los ntawm kev siv cov xim tsawg dua tab sis lub zog zoo tagnrho.
Dhau li ntawd, zoo dispersibility kuj qhia tau hais tias tus nqi tshwj xeeb thaum lub sij hawm tsim khoom. Piv txwv li,Pigment Yellow 180, qhov ua tau zoo ntawm cov xim no tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm PP fiber ntau, txawm li cas los xij nws yuav tsum tau rov ua cov pelletizing kom ua tiav cov kev sib txuam sib luag rau cov kev xav tau hnyav. Raws li txoj cai, pigments dispersibility nyob ntawm lawv 'gene' —— txawm peb paub tias qhov txwv sab sauv ntawmPigment Yellow 180tuaj yeem ua tiav peb qhov kev thov rau daim ntawv thov, tab sis peb yuav tsum muab tso rau hauv ntau shear force thiab dispersing tus neeg sawv cev kom ua tiav lub hom phiaj.

Yog li, peb paub tias qhov kev faib tawm sab saum toj tsis yog yooj yim rau txoj kev tab sis thov kev siv zog ntxiv thiab tus nqi. Ntxiv cov tswv yim xws li rov ua pelletizing, yog khib nyiab rau cov neeg tsim khoom ntawm kev tsim khoom thiab lub sijhawm.
Peb'Ua ntej'series yog tag nrho xav txog cov teeb meem siv tswv yim saum toj no. Txhawm rau txhim kho qhov sib txawv, peb siv 'ceev thiab yooj yim dispersing' raws li cov ntsiab lus tseem ceeb ntawm cov khoom tsim. Nrog rau lub hom phiaj rau tag nrho dispersibility los ntawm ib lub sij hawm pelletizing, peb ua nruj tswj Performance index: Tag nrho'Preperse-S'series yog ua raws li cov kev cai filament los ntawm ib lub sij hawm pelletizing thiab FPV yuav tsum qis dua 1, nyob rau hauv cov xwm txheej ntawm 1400 meshes, 60g xim los ntawm lub tshuab FPV (40% pigment loading masterbatch dilute mus rau 8%).
Feem ntau, ua masterbatch los ntawm ib lub sij hawm pelletizing tsis txaus los mus rau ib qho kev ua tau zoo FPV rau kev siv nruj, xws li filament, nyias zaj duab xis thiab lwm yam. Cov 'Preperse' series yog ib qho kev daws teeb meem zoo tshaj plaws rau qhov kev txwv no. Tau txais txiaj ntsig los ntawm kev ua haujlwm ua ntej disperse thiab zoo heev dispersibility, 'Preperse' pigment npaj pab ua kom muaj xim xim cov ntsiab lus mono masterbatch uas tau txais cov xim feem pua ntawm 40% mus rau 50%. Txawm tias qee qhov 'ungifted' pigments uas tsis tuaj yeem cuam tshuam cov caj ces kuj ua haujlwm tawm cov ntsiab lus siab xim mono masterbatch. Piv txwv li,Pigment Violet 23, paub tias yog qhov nyuaj tshaj plaws-dispersible pigment, pebtsimPreperse Violet RL uas muaj70% pigment tus nqi thiab ua kom tiav 40% mono masterbatch, nrog FPV ntawm 0.146 bar / g (saib hauv daim duab hauv qab).
Tsis tas li ntawd, peb'Ua ntej'series tuaj yeem tau txais cov xim zoo nkauj yam tsis muaj cov cuab yeej siv siab shear quab yuam. Piv txwv li,'Preperse' pigment npajtuaj yeem siv los hloov covximthiabmono masterbatchthaum ua masterbatch los yog davhlau ya nyob twg cov khoom uas ncaj qha los ntawm ib tug ntsia hlau extruder.
Rau cov neeg tsim khoom masterbatch, lawv tuaj yeem tshem tawm cov txheej txheem tam sim no ntawm kev ua mono masterbatch lossis SPC tab sis ua ntej ua cov xim sib xws. Los ntawm txoj kev no, cov neeg siv txuag sijhawm ntau dua thiab tau txais txiaj ntsig los ntawm kev ua haujlwm siab dua.
