Indima yeIarhente yokusasaza iMFkukunciphisa ixesha kunye namandla afunekayo ukugqiba inkqubo yokusabalalisa, ukuzinzisa ukusabalalisa kwe-pigment, ukuguqula iipropati ze-pigment particles, ukulungelelanisa ukuhamba kweengqungquthela ze-pigment, njl.
Ifakwe kule miba ilandelayo:
Nciphisa ixesha namandla eIarhente yokusasaza iMFinkqubo
Ngokudibana, umphezulu wamasuntswana e-pigment unokuguqulwa ngokukhawuleza ukusuka kwi-"gas-solid interface" ukuya kwi-"liquid-solid interface". Ngaloo ndlela ukunciphisa ixesha kunye namandla afunekayo ekusileni.
Nciphisa i-viscosity
Ukusetyenziswa kwe-dispersant kunokunciphisa i-viscosity kunye nokwandisa umthamo wokulayisha we-pigment.
Thintela i-flocculation kwaye ubuyele kwindawo erhabaxa
I-Disperant kumphezulu we-pigment, nge-electrostatic repulsion okanye isithintelo se-steric ukunqanda umtsalane kunye nokuvala, ukuze kwandiswe uzinzo lwenkqubo.
Kufanelekile ukukhankanya ukuba i-pigment particles icolekileyo, ubukhulu bendawo ethile, ukuphakama kwamandla omhlaba, imfuno yamandla aphezulu e-adsorption.Iarhente yokusasaza iMF, ngoko ke inani le-dispersant likwahambelana nomgangatho wokuncamathisela.
Thintela iinwele ezidadayo
Ngokufana nomgaqo ongasentla, undoqo wozinzo lwe-dispersant.
Phucula ukusebenza kombala
Phucula amandla okuthambisa, ukwandisa umboniso wombala. Ukuphucula ukugcwala kunye nokungafihli kwee-pigments eziphilayo, kunye nokwandisa amandla okufihla ii-pigments ze-inorganic.
Impembelelo ekusebenzeni kwefilimu yepeyinti
I-Dispersant ayiyi kushiya ifilimu yepeyinti emva kokwenza ifilimu, kodwa njengenxalenye esisigxina yefilimu yepeyinti ikhona kwifilimu yepeyinti, ayinayo impembelelo encinci ekusebenzeni kwefilimu yepeyinti.
Impembelelo ekuxhathiseni amanzi:
Ukusuka kumgaqo-nkqubo we-dispersant, i-essential of dispersant i-surfactant, kunye neempawu ze-amphiphilic. Ngoko ke, i-dispersant ngokuqinisekileyo iya kuba ne-hydrophilic ethile, kwifilimu yepeyinti inempembelelo enkulu ekuchaseni amanzi.
I-Sv-246h i-superdispersant yamanzi esekelwe kumanzi yimveliso eguquliweyo ye-hydrophobic, ifilimu eyomileyo, ayiyi kuchaphazela ifilimu ngokwayo ukumelana namanzi.
Ifuthe kwiglosi:
Iglosi yefilimu yepeyinti yepeyinti iphuma ngokuyinhloko ekubonakalisweni kokukhanya kwifilimu yepeyinti, kwaye umgangatho womhlaba uxhomekeke kubukhulu becala lecandelo ngalinye, kunye nokuhambelana nokusabalalisa.
I-Dispersant dispersion, ukuzinza ngokungathandabuzekiyo luncedo olukhulu kwi-gloss yefilimu yepeyinti. Kodwa kwakhona kufuneka uqwalasele i-dispersant ngokwayo kunye ne-resin ngokwayo ukuhambelana. Ngokomzekelo, i-SV-246H i-superdispersant esekelwe emanzini inokuhambelana kakuhle kwiinkqubo ze-acrylic ezisekelwe emanzini, kwaye inokunyusa i-gloss nge-2-3% xa kuthelekiswa ne-dispersants eqhelekileyo njenge-755W kunye ne-190.
isiphelo
I-Dispersant iyongezo ebaluleke kakhulu ekugqumeni.
Ayifani kuphela nefilimu eyenza abancedisi, umlawuli we-pH uya kuguquguquka kwinkqubo yokomisa; Ikwahluke kwi-agent yokumanzisa, i-agent ekhupha amagwebu kunye ne-ejenti yokuqina.
Ngenxa yokuba ihlala ikhona kwifilimu yepeyinti kwaye inomxholo ophezulu, inempembelelo enkulu ekusebenzeni kwefilimu yepeyinti. Ngoko ke, ukukhethwa kunye nokusetyenziswa kwe-dispersant kunceda kakhulu ekusebenzeni kwengubo.
