Ngaba uyazi dispersant?Yeyiphi eyona dispersant ilungileyo?

I-Dispersant, njengoko igama libonisa, kukusasaza ngokufanelekileyo umgubo ohlukeneyo kwisinyibilikisi, kwaye wenze izinto eziqinileyo ezahlukeneyo zinqunyanyiswe kwisinyibilikisi (okanye ukusasazwa) ngomgaqo othile wokuchasa intlawulo okanye isiphumo se-polymer steric.
Ukuhlelwa kwemveliso:
1. I-wax ye-molecular ephantsi
I-wax ye-molecular ephantsi iluhlu lwee-oligomers ezineempawu ezahlukeneyo, ezenziwe nge-polyethylene eyahlukeneyo (i-homopolymer okanye i-copolymer), i-polypropylene, i-polystyrene okanye ezinye izinto eziguqulwayo ze-polymer ngokuqhekeka kunye ne-oxidation.
Iimveliso zayo eziphambili ziquka i-homopolymer, i-homopolymer ene-oxidized, i-ethylene acrylic acid copolymer, i-ethylene vinyl acetate copolymer kunye ne-ionomer ye-molecular ephantsi.Polyethylene waxyeyona isetyenziswa kakhulu.

2. I-fatty acids, i-aliphatic amides kunye ne-esters
Indibaniselwano ye-stearamide kunye notywala obuphezulu kunokuphucula ukuthambisa kunye nokuzinza kwe-thermal.I-dosage (iqhezu lobuninzi, efanayo ngezantsi) yi-0.3% - 0.8%.Isenokusetyenziswa njenge-lubricant ye-polyolefins;I-Hexenyl distearamide, ekwabizwa ngokuba yi-ethylene distearamide, yindawo ephezulu yokunyibilika ye-lubricant enomthamo we-0.5% ~ 2%;I-Monoglyceride stearate, iGlyceryl tristearate;Umthamo we-oleoyl ngu-0.2% ~ 0.5%;I-Hydrocarbon iparafini eqinileyo, indawo yokunyibilika engama-57 ~ 70 ℃, ayinyibiliki emanzini, inyibilika kwizinyibilikisi zendalo, ukusasazwa okulambathayo, ukuhambelana kunye nozinzo lwe-thermal kwi-resin, kwaye ithamo lingaphantsi kwe-0.5%.
3. Iwax yeparafini
Nangona iparafini sisithambisi sangaphandle, yi-hydrocarbon ye-non-polar straight chain, engakwazi ukumanzisa umphezulu wesinyithi, oko kukuthi, ayikwazi ukuthintela i-PVC kunye nezinye ii-resin ukuba zibambelele eludongeni lwesinyithi.Iyakwazi ukudlala umphumo we-synergistic kuphela xa isetyenziswe ngokudibanisa ne-stearic acid kunye ne-calcium stearate.
Iparafini elulwelo: indawo yomkhenkce ngu – 15-35 ℃.Ngexesha lokukhutshwa kunye nokubunjwa kwenaliti, inokungahambelani kakuhle kunye ne-resin, kwaye inani elongezelelweyo lihlala li-0.3% - 0.5%.Ukuba ininzi kakhulu, iya kuphazamisa ukusebenza kokucubungula.
Iparafini yeMicrocrystalline: ifumaneka kwinkqubo yokusulungekiswa kwepetroleum.Ubunzima bayo bemolekyuli bukhulu kwaye kukho isomers ezininzi.Indawo yokunyibilika yi-65-90 ℃.Ine-lubricity elungileyo kunye nokuzinza kwe-thermal, kodwa ukusasazwa kakubi.Idosi ngokubanzi yi-0.1% - 0.2%.Kungcono ukuba isetyenziswe kunye ne-butyl stearate kunye ne-fatty acids ephezulu.op wax

4. Iisepha zentsimbi
Iityuwa zesinyithi ze-fatty acids eziphezulu, ezibizwa ngokuba ziisepha zetsimbi, ezifana ne-barium stearate, zifanelekile kwiindidi zeplastiki ezinomlinganiselo we-0.5%;I-Zinc stearate ifanelekile kwi-polyolefin, i-ABS, njl., kunye ne-dosage ye-0.3%;I-calcium stearate ifanelekile kwiiplastiki eziqhelekileyo kunye ne-lubrication yangaphandle, kunye ne-dosage ye-0.2% - 1.5%;Ezinye iisepha ze-stearic acid ezifana ne-cadmium stearate, i-magnesium stearate kunye ne-copper stearate.
Umsebenzi weMveliso:
1. Ukuphucula ukukhanya;
2. Thintela umbala odadayo kunye neentyatyambo;
3. Ukuphucula amandla okufaka imibala;
4. Ukunciphisa i-viscosity kunye nokwandisa ukulayishwa kwe-pigment;
5. Ukwandisa uzinzo lokugcina;
6. Ukwandisa ukuphuhliswa kombala kunye nokuzaliswa kombala
7. Ukwandisa ukukhanya (i-organic pigments) okanye amandla okufihla (ii-pigments ze-inorganic).
Umgaqo wemveliso:
Kwinkqubo yokuvelisa i-Color Masterbatch, i-pigment dispersion ibaluleke kakhulu ikhonkco yokuvelisa, ehambelana ngqo nokugcinwa, ukusetyenziswa, ukubonakala kunye nokusebenza kwe-masterbatch.Ke ngoko, ukhetho olufanelekileyo lwe-dispersant lubaluleke kakhulu ikhonkco lokuvelisa.
Iimfuno zokuthenga:
1. Ukusebenza kakuhle kokusasazwa kokuthintela ukudityaniswa kwamasuntswana okugcwalisa;
2. Inokuhambelana okufanelekileyo kunye ne-resin kunye ne-filler kunye nokuzinza okuhle kwe-thermal;
3. I-fluidity elungileyo ngexesha lokwenziwa kunye nokucubungula, ngaphandle kokubangela ukukhukuliseka kombala;
4. Ayichaphazeli ukusebenza kweemveliso, ezingenayo ityhefu kunye nexabiso eliphantsi;
5. Umthamo we-dispersant ngokubanzi yi-5% yobunzima be-masterbatch.
