Kutheni usenzaI-Disperant NNOumsebenzi?
I-Disperant NNOiimolekyuli ziqulethe amaqela e-anchoring kunye neenxalenye zokuzinzisa. Indima yeqela le-anchoring kukubonelela ngamandla anamandla aneleyo okubopha kwiinqununu ze-pigment filler. Iimolekyuli ezisasazwayo aziwi kumphezulu wamasuntswana, nto leyo eyimfuneko ukuze i-dispersant isebenze. Umsebenzi wenxalenye yokuzinzisa kukuzinzisa amasuntswana e-pigment aggregate ahlakazwe ngamandla omatshini ngokugxothwa kwe-electrostatic kunye nokumelana nendawo kwisigaba solwelo ukuthintela amasuntswana ukuba adityaniswe.
Kwizinyibilikisi eziphilayo, xa inxalenye ezinzileyo yeI-Disperant NNOuzinzisa iinqununu ze-pigment ezihlakaziweyo ngokuchasana kwendawo, xa i-spacing ye-disperant particles incinci kunobukhulu be-solvent chain, i-solvent chain chain chain kwaye i-entropy iyancipha. Emanzini, i-ionization yenzeka malunga namaqela e-ionic ukwenza umaleko ophindwe kabini, kunye ne-electrostatic repulsion ithintela ukuhlangana kwamasuntswana. Ukuba i-polyether engeyiyo i-ionized izinzile, i-polyether izinzisa amasuntswana e-pigment ahlakaziweyo ngokumelana nendawo.
Kwinkqubo yokwenza i-pulp kunye nephepha, inani elikhulu le-dispersants yeekhemikhali zephepha liyadingeka ukuxazulula iingxaki zokusabalalisa, ukugcinwa, ukuhluzwa kunye nokunye. Ukongeza izisasazi zeekhemikhali kwi-pulp kunokunciphisa ukujikeleza kwefayibha kwaye lenze iphepha ligudiswe kwaye lisebenze kakuhle. Ngokuqhelekileyo, izongezo zemichiza zisetyenziselwa ukuhluza i-pulp, ezifana nokugeleza kwe-AIDS, izihluzi, i-dispersants, i-ejenti ezomelezayo, i-agent ekhupha amagwebu, i-preservatives, i-enzymes ye-biological, njl. Kolu luhlu lwamalungiselelo, abanye babodwa, abanye baxutywe, basebenzisane. ukuphucula umgangatho wephepha, ukuphucula ngokufanelekileyo ukusebenza kakuhle kwemveliso, ukunciphisa iindleko zokuvelisa.
I-Fiber yinto ephambili echaphazela umgangatho wephepha kwinkqubo yokwenza iphepha. Njengolunye uhlobo lwefiber olude aluhambelani kakuhle, ukwenza izongezo, izihluzi kunye nokunye kude enye kwenye, kwaye ke kunzima ukufumana ukusebenza okufanayo, amandla afanelekileyo ephepha. Nangona kunjalo, ngokongezwa kwe-dispersant efanelekileyo, umphezulu weengqungquthela eziqinileyo unokwenza isakhiwo se-bimolecular, kunye neqondo lokufuma kwamasuntswana aqinileyo anokuphuculwa. Ezinye i-fiber dispersants ezilungileyo zifuna iipropathi ezithile zepyrolytic, ezinokuphucula ukusebenza kakuhle kokusasazwa ngokunyuka kwamaqondo obushushu. Emva koko unciphise i-viscosity ye-pulp, uphucule umgangatho wephepha kunye nokuthamba.
