iarhente yokuxuba i-M30/A-102W

inkcazo emfutshane:

I-Emulsifier luhlobo lwento enokwenza umxube wezinto ezimbini okanye ngaphezulu ezingadibaniyo zenze i-emulsion ezinzileyo. Umgaqo wayo wesenzo ukwinkqubo ye-emulsion, isigaba esisasazekileyo ngendlela yamaconsi (ii-microns) asasazekileyo kwisigaba esiqhubekayo, sinciphisa uxinzelelo lwe-interfacial yecandelo ngalinye kwinkqubo exutyiweyo, kwaye umphezulu we-droplet wenze ifilimu eqinileyo okanye ngenxa yokutshaja kwe-emulsifier kunikwa ekwakhiweni komphezulu we-droplet we-electric double layer, ukuthintela amaconsi ukuba ahlangane, kunye nokugcina i-emulsion efanayo. Ukusuka kwimbono yesigaba, i-emulsion isenokwahluka. Isigaba esisasazekileyo kwi-emulsion sinokuba yi-water phase okanye i-oil phase, uninzi lwazo luyi-oyile. Isigaba esiqhubekayo sinokuba yi-oyile okanye amanzi, kwaye uninzi lwazo ngamanzi. I-emulsifier yi-surfactant eneqela le-hydrophilic kunye neqela le-lipophilic kwi-molecule. Ukuze kuvezwe iimpawu ze-hydrophilic okanye ze-lipophilic ze-emulsifier, "ixabiso le-hydrophilic lipophilic equilibrium (ixabiso le-HLB)" lidla ngokusetyenziswa. Okukhona ixabiso le-HLB liphantsi, kokukhona iimpawu ze-lipophilic ze-emulsifier ziqina. Ngokwahlukileyo koko, okukhona ixabiso le-HLB liphezulu, kokukhona i-hydrophilicity iqina. Ii-emulsifier ezahlukeneyo zinamaxabiso ahlukeneyo e-HLB. Ukuze kufunyanwe ii-emulsions ezizinzileyo, kufuneka kukhethwe ii-emulsifiers ezifanelekileyo.

Izicelo

A: Intsimi ye-polymerization: ifanelekile ukulungiselela ubungakanani obuphakathi bee-vinyl acetate, i-acrylic acetate kunye ne-pure acrylic emulsion. Ukwabelana nge-N-hydroxyl ngaphandle kokunciphisa ukusebenza kwe-crosslinking. Xa isetyenziswa nee-emulsifiers ezifana ne-MA-80 kunye ne-IB-45, inokuphucula ngempumelelo ubungakanani bee-particle kwaye ivelise ukunamathela okungcono.

B: Amasimi angengo-polymeric: izinto zokucoca, iimveliso zeekhemikhali kunye neeshampu ezinamandla okubulala iintsholongwane; Isamente enefoam, iiphaneli zodonga kunye nezincamathelisi; Inamandla okuthwala ii-cationic surfactants kunye nee-polyvalent cations. Yinto elungileyo yokwandisa isinyibilikisi kunye ne-dispersant kwiinkqubo ze-resin kunye ne-pigment ezinexabiso eliphakathi le-HLB.

Ukusebenza
Izinzile kakuhle nge-electrolyte kunye nozinzo loomatshini

1. Chaza
I-M30 luhlobo lwe-emulsifier ephambili ebalaseleyo, engenazo i-APEO, i-propylene ecocekileyo, i-acetate propylene, i-styrene propylene kunye ne-EVA emulsion polymerization system. I-M30 idibanisa amaqela e-polar anionic kunye namaqela angengo-polar non-ionic, kwaye olu lwakhiwo lwe-molecular olulodwa lwenza i-emulsion ibe nokuzinza okuhle kwe-electrolyte kunye nokuzinza koomatshini.

2. Imisebenzi ephambili kunye neenzuzo
Ngaphandle kwe-APEO

3. Amasimi esicelo
A. Intsimi ye-polymerization: ifanelekile ukulungiselela ubungakanani obuphakathi bee-vinyl acetate, i-acrylic acetate kunye ne-pure acrylic emulsion. Ukwabelana nge-N-hydroxyl ngaphandle kokunciphisa ukusebenza kwe-crosslinking. Xa isetyenziswa nee-emulsifiers ezifana ne-MA-80 kunye ne-IB-45, inokuphucula ngempumelelo ubungakanani bee-particle kwaye ivelise ukunamathela okungcono.

B. Amasimi angengo-polymeric: izinto zokucoca, iimveliso zeekhemikhali kunye neeshampu ezinamandla okubulala iintsholongwane; Isamente enefoam, iiphaneli zodonga kunye nezincamathelisi; Inamandla okuthwala ii-cationic surfactants kunye nee-polyvalent cations. Yinto elungileyo ekhulisa isinyibilikisi kwaye isasaza iinkqubo ze-resin kunye ne-pigment ezinexabiso eliphakathi le-HLB.

4. Ukusetyenziswa
Ukuze isebenze kakuhle, kuyacetyiswa ukuba kuncitshiswe kwaye kongezwe, kwaye ukusetyenziswa kuxhomekeke kakhulu kwinkqubo yesicelo. Umsebenzisi kufuneka amisele ubungakanani bokongeza obufanelekileyo ngokuvavanya ngaphambi kokuba asebenzise.
