Lapho wenza upende, i-viscosity ye-HPMC (Hydroxypropyl Methylcellulose) idlala indima ebalulekile ekuzuzeni ukuvumelana okufiselekayo, ukusabalala, kanye nokusebenza kukonke.Lesi sihloko sihlose ukuhlinzeka ngendlela yesayensi yokunquma i-viscosity ye-HPMC ephelele yokwakhiwa kopende, kucatshangelwa izici ezifana nohlobo lwe-pigment, indlela yokufaka isicelo, nezici zopende ezifiswayo.
Qonda Iqhaza Le-HPMC Ekwakhiweni Kwepende:
I-HPMC isebenza njengesengezo esisebenza ngezindlela eziningi ekwenziweni kopende, okunikela ekulawulweni kwe-viscosity, ukugcinwa kwamanzi, kanye nezakhiwo zefilimu.I-viscosity yayo ithonya ngokuqondile ukugeleza nezici zokulinganisa zopende, kanye nekhono layo lokunamathela ezindaweni ezihlukahlukene.
Cabangela uhlobo lwe-Pigment nokugxila:
Imibala ehlukahlukene idinga amazinga ahlukahlukene e-viscosity ye-HPMC ukuze kuzuzwe ukuhlakazeka okuphelele nokuzinza ekwakhekeni kopende.Ngokuvamile, izingulube ezigxilile kakhulu noma ezisindayo, njenge-titanium dioxide noma i-iron oxide, zingadinga i-viscosity ephakeme ye-HPMC ukuze kugcinwe ukumiswa okufanayo nokuvimbela ukuzinza.Imibala ekhanyayo, efana nodayi bendalo noma obala, ingadinga i-viscosity ephansi ye-HPMC ukuze kuqinisekiswe ukuhlakazeka okufanele ngaphandle kokuthikameze ukubonakala.
Nquma Indlela Yokufaka Isicelo kanye Nezimpawu Zopende:
Indlela yokufaka isicelo kanye nezici zopende ezifiselekayo nazo zinomthelela ekubonakaleni kwe-HPMC okuphelele.Ngokwesibonelo:
a.Isicelo Sebhulashi/I-Roller: I-viscosity ephakeme i-HPMC ivamise ukuncanyelwa ukusebenzisa ibhulashi noma i-roller ukuze kuqinisekiswe ukulawulwa okungcono kopende, ukuchelela okuncishisiwe, nokugcinwa kwebhulashi/irola okuthuthukisiwe.
b.I-spray application: I-HPMC ye-viscosity ephansi ijwayele ukusetshenziselwa isifutho ukuze kube lula ukwenziwa kwe-atom futhi kufinyelele ukumboza ngisho.
c.I-Sag Resistance: Ukuze uthuthukise ukumelana nokuntenga futhi uvimbele upende ukuthi ungaconsi noma uhlehle endaweni eqondile, i-viscosity ephakeme i-HPMC ingase idingeke.
Yenza ukuhlolwa kwe-Rheological:
Ukuze unqume ngokwesayensi i-viscosity ye-HPMC ephelele yokwakhiwa kopende, ukuhlolwa kwe-rheological kungenziwa.Lezi zivivinyo zikala ukugeleza nokuziphatha kokuguqulwa kopende ngaphansi kwezimo ezilawulwayo.Imiphumela ingaqondisa ukukhethwa kwe-viscosity ye-HPMC ngokucabangela izici ezifana nesilinganiso sokugunda, ukucindezeleka kwe-shear, namaphrofayili e-viscosity.
Hlola futhi Ulungise:
Ngokusekelwe emiphumeleni yokuhlolwa kwe-rheological, uhla lwama-viscosity we-HPMC lungakhonjwa njengabangase bangenele ekwakhiweni kopende.Yenza izivivinyo ezincane ngokwenza amasampula opende anama-viscosity e-HPMC ahlukahlukene ngaphakathi kwebanga elihlonziwe.Linganisa amapharamitha abalulekile njengezakhiwo zohlelo lokusebenza, izinga, ukumelana ne-sag, nezici zokomisa.Lungisa i-viscosity ye-HPMC njengoba kudingeka ukuze uzuze ukusebenza kopende okufunayo.
Ukunquma i-viscosity ye-HPMC ephelele yokwakhiwa kopende kudinga indlela yesayensi ecabangela izici ezifana nohlobo lwe-pigment, indlela yokufaka isicelo, nezici zopende ezifiswayo.Ngokuqonda indima ye-HPMC, ukwenza izivivinyo ze-rheological, nokuhlola nokulungisa amasampula okwakheka, abakhiqizi bakapende bangafinyelela i-viscosity efanelekile yokuthuthukisa ukugeleza kukapende, ukulevelisa, ukunamathela, kanye nokusebenza kukonke.Kubalulekile ukushaya ibhalansi efanele ukuze uzuze izici zopende ozifunayo kuyilapho ugcina izidingo ezingokoqobo zendlela yokufaka isicelo.
