Dispersant, raws li lub npe qhia, yog tsim nyog disperse ntau yam hmoov nyob rau hauv cov kuab tshuaj, thiab ua rau ntau yam khib nyiab stably raug tshem tawm nyob rau hauv cov kuab tshuaj (los yog dispersion) los ntawm ib tug tej yam nqi repulsion txoj cai los yog polymer steric nyhuv.
Kev faib khoom:
1. Tsawg molecular ciab
Tsawg molecular wax yog cov oligomers uas muaj cov khoom sib txawv, uas yog ua los ntawm ntau yam polyethylene (homopolymer lossis copolymer), polypropylene, polystyrene lossis lwm yam khoom siv polymer hloov kho los ntawm kev tawg thiab oxidation.
Nws cov khoom tseem ceeb suav nrog homopolymer, oxidized homopolymer, ethylene acrylic acid copolymer, ethylene vinyl acetate copolymer thiab qis molecular ionomer.Polyethylene waxyog feem ntau siv.

2. Fatty acids, aliphatic amides thiab esters
Kev sib xyaw ntawm stearamide thiab cawv ntau dua tuaj yeem txhim kho lubricity thiab thermal stability.Qhov ntau npaum li cas (feem ntau, tib yam hauv qab no) yog 0.3% - 0.8%.Nws kuj tseem siv tau los ua cov roj nplua nyeem rau polyolefins;Hexenyl distearamide, tseem hu ua ethylene distearamide, yog lub siab melting point lubricant nrog ntau npaum li cas ntawm 0.5% ~ 2%;Monoglyceride stearate, Glyceryl tristearate;Qhov ntau npaum ntawm oleoyl yog 0.2% ~ 0.5%;Hydrocarbon paraffin khoom, melting point 57 ~ 70 ℃, insoluble nyob rau hauv dej, soluble nyob rau hauv cov organic solvents, tsis zoo dispersion, compatibility thiab thermal stability nyob rau hauv lub resin, thiab qhov ntau npaum yog feem ntau tsawg tshaj li 0.5%.
3. Paraffin ciab
Txawm hais tias paraffin yog cov roj nplua nyeem sab nraud, nws yog cov tsis muaj polar ncaj saw hydrocarbon, uas tsis tuaj yeem ntub cov hlau nto, uas yog, nws tsis tuaj yeem tiv thaiv PVC thiab lwm yam resins los ntawm adhering rau hlau phab ntsa.Nws tuaj yeem ua kom muaj kev sib koom ua ke tsuas yog thaum nws siv nrog stearic acid thiab calcium stearate.
Kua paraffin: qhov chaw khov yog -15-35 ℃.Thaum lub sij hawm extrusion thiab txhaj tshuaj molding, nws muaj qhov tsis zoo sib xws nrog cov resin, thiab qhov sib ntxiv yog feem ntau 0.3% - 0.5%.Yog tias nws ntau dhau, nws yuav ua rau kev ua haujlwm tsis zoo.
Microcrystalline paraffin: nws tau txais los ntawm cov txheej txheem roj av refining.Nws cov txheeb ze molecular hnyav yog loj thiab muaj ntau isomers.Lub melting point yog 65-90 ℃.Nws muaj zoo lubrication thiab thermal stability, tab sis tsis zoo dispersion.Qhov ntau npaum yog 0.1% - 0.2%.Nws yog qhov zoo tshaj plaws los siv ua ke nrog butyl stearate thiab ntau dua fatty acids.ope ua 

4. Hlau xab npum
Hlau ntsev ntawm cov roj fatty acids ntau dua, hu ua hlau soaps, xws li barium stearate, yog haum rau ntau yam plastics nrog ntau npaum li 0.5%;Zinc stearate yog tsim rau polyolefin, ABS, thiab lwm yam., nrog rau qhov ntau npaum li cas ntawm 0.3%;Calcium stearate yog tsim rau cov yas dav dav thiab lubrication sab nraud, nrog rau qhov ntau npaum li cas ntawm 0.2% - 1.5%;Lwm yam stearic acid xab npum xws li cadmium stearate, magnesium stearate thiab tooj liab stearate.
Khoom ua haujlwm:
1. Txhim kho luster;
2. Tiv thaiv cov xim ntab thiab paj;
3. Txhim kho xim muaj zog;
4. Txo viscosity thiab nce pigment loading;
5. Ua kom ruaj khov;
6. Txhim kho xim thiab xim saturation
7. Ua kom pob tshab (organic pigments) lossis zais lub zog (inorganic pigments).
Khoom ntsiab lus:
Nyob rau hauv cov txheej txheem ntau lawm ntawm Xim Masterbatch, pigment dispersion yog ib qho tseem ceeb ntawm cov khoom txuas, uas yog ncaj qha ntsig txog kev khaws cia, daim ntawv thov, tsos thiab kev ua tau zoo ntawm masterbatch.Yog li ntawd, kev xaiv tsim nyog ntawm dispersant yog ib qho tseem ceeb ntawm kev tsim khoom txuas.
Kev yuav khoom:
1. Kev ua tau zoo dispersion los tiv thaiv kev sib sau ua ke ntawm cov khoom muab tub lim;
2. Nws muaj kev sib raug zoo nrog cov resin thiab muab tub lim thiab zoo thermal stability;
3. Zoo fluidity thaum lub sij hawm tsim thiab ua, tsis ua rau xim drift;
4. Nws tsis cuam tshuam rau kev ua haujlwm ntawm cov khoom, tsis muaj tshuaj lom thiab pheej yig;
5. Qhov ntau npaum ntawm dispersant feem ntau yog 5% ntawm qhov loj ntawm masterbatch.
