Iingubo zokwaleka ze-HPMC ziya zithandeka ngakumbi kwindawo yokugquma ngenxa yobuhlobo bazo bokusingqongileyo, ukusetyenzwa lula, ukuncamathela okulungileyo, kunye neempawu ezibalaseleyo zokwenza ifilim. Nangona kunjalo, njengakuyo nayiphi na into yokugquma, ukusetyenziswa kwee-coatings ze-HPMC kufuna izongezo ezithile ukunceda ukufezekisa iipropathi ezinqwenelekayo, kubandakanya i-dipersants kunye ne-thickeners.
I-Dispersants izongezo ezibalulekileyo kwiingubo ze-HPMC kuba zithintela i-particle okanye i-pigment agglomeration, enokuthi ibeka phantsi umgangatho wefilimu, iphazamise inkqubo yokugqoka, kunye nokunciphisa ukusebenza kwengubo. Umsebenzi we-dispersant ku-adsorb kumphezulu wamasuntswana ukwenza umaleko okhuselayo ogxotha i-electrostatically amanye amasuntswana kwaye uwathintele ekubeni aglomerating. Iingubo ze-HPMC zihlala zisebenzisa ii-polymer dispersants, ezinenzuzo yokuthintela ukuhlaliswa kwamasuntswana kuphela, kodwa kunye nokunciphisa i-viscosity ye-slurry, ukuphucula ukuguquguquka kwayo kunye nokufana kwengubo.
I-Thickeners, kwelinye icala, idlala indima ephambili ekuphuculeni i-viscosity kunye neempawu ze-rheological zeengubo ze-HPMC. I-thickener efanelekileyo kufuneka ibe nobunzima obuphezulu be-molecular kunye ne-solubility efanelekileyo yamanzi ukuqinisekisa ukufakwa lula kunye nokusabalalisa kwi-matrix yepeyinti. I-Thickeners yandisa i-viscosity kunye noxinzelelo lwesivuno se-coating, ivumela ukuba ibambelele bhetele kwiindawo kwaye yenze ifilimu egudileyo, efanayo. Ukongeza, i-thickeners iphucula ulawulo lwe-rheology yokwambathisa, ikwenza kube lula ukuyifaka kunye nokusebenzisa iindlela ezahlukeneyo zokusebenzisa.
Ukudityaniswa kwe-dispersants kunye ne-thickeners kunokuphucula kakhulu ukusebenza kunye nomgangatho weengubo ze-HPMC ngokwandisa ukusabalalisa kunye ne-viscosity yabo. Ukongeza, ukuqulunqwa okwenziwe ngononophelo kunokunyusa ukuzinza, ukuphuhliswa kombala kunye nokumelana nemozulu yeengubo. I-dispersers ezifanelekileyo kunye ne-thickeners kufuneka zikhethwe ngokusekelwe kwiimfuno ezithile zesicelo sokugquma, njengomgangatho we-substrate, ubukhulu bengubo, indlela yokufaka isicelo kunye nokuphela kokusetyenziswa kwendawo.
Phakathi kwe-dispersants kunye ne-thickeners enokusetyenziswa kwiingubo ze-HPMC, i-cellulose derivatives ifumene ingqwalasela ebanzi ngenxa yokuhambelana kwabo kakuhle kunye ne-HPMC kunye nemimiselo yokusingqongileyo kwishishini lokugqoka. Ngokomzekelo, i-carboxymethyl cellulose (CMC) inokusasaza ngokufanelekileyo kwaye imise ii-pigments kwiingubo ze-HPMC ngelixa iphucula i-rheology kunye nokusabalalisa ubungakanani besuntswana. Ngokufanayo, i-methylcellulose (MC) yinto esetyenziswa ngokuqhelekileyo kwiingubo ze-HPMC ngenxa yokukwazi ukwenza inethiwekhi yejel eyomeleleyo kunye nokugcina i-viscosity ezinzileyo phezu kwe-pH ebanzi kunye noluhlu lobushushu.
Enye inzuzo yokusebenzisa i-cellulose derivatives njenge-dispersants kunye ne-thickeners kwi-coatings ye-HPMC kukuba ayinayo ityhefu, i-biodegradable kwaye ihlaziywa, inciphisa impembelelo yazo yokusingqongileyo ngexesha lemveliso, ukusetyenziswa kunye nokulahlwa. Ukongeza, iipropathi ezikhethekileyo zomzimba kunye neekhemikhali zezinto eziphuma kwi-cellulose zinokunikezela ngeempawu ezithile kwiingubo ze-HPMC, ezifana nokugcinwa kwamanzi, ukuthambisa kunye nokukwazi ukwenza ifilimu.
I-Dispersants kunye ne-thickeners izongezo ezibalulekileyo kwiingubo ze-HPMC zokuqinisekisa ukusasazeka, i-viscosity kunye nokusebenza. Ngokukhetha ngononophelo kunye nokuqulunqwa kwee-dispersants ezifanelekileyo kunye ne-thickeners, ukusebenza kunye nomgangatho weengubo ze-HPMC zinokuphuculwa, okukhokelela ekusebenzeni kakuhle kokwambathisa, ukubambelela kunye nokuqina. Ukongeza, ukusetyenziswa kwezinto eziphuma kwi-cellulose ezihambelana nokusingqongileyo kunye ne-cellulose ezihlaziywayo njenge-dispersants kunye ne-thickeners kunceda ukunciphisa impembelelo yokusingqongileyo yeengubo ze-HPMC ngelixa ziphucula ukusebenza kunye nokusebenza kwazo.
