Hydroxypropyl methylcellulose e na le li-viscosity tse tharo tsa 100,000, 150,000, le 200,000. Viscosity ke tšobotsi ea phallo ea mokelikeli oa enke.
Sesupo sa bongata ba khanyetso (kapa khohlano ea ka hare) ho sisinyeha. Nakong ea khatiso ea offset, ho hlokahala hore ho be le viscosity e itseng ho boloka phetiso ea enke ka tloaelo.
Ke boemo bo ka sehloohong ba ho pepa le ho fetisoa, hape ke boemo ba bohlokoa ba ho khetholla ho potlaka, ho hlaka le ho khanya ha khatiso. Viscosity ea enke
Haeba e le khōlō haholo, ho tla ba thata ho fetisetsa le ho fetisetsa, e le hore palo ea enke ka moralo e be e sa lekaneng, e leng se etsang hore ho be le bofeela ba litšoantšo le mongolo ho theha mohlala. Ka ho tšoanang, viscosity
Haeba e le khōlō haholo, ho boetse ho bonolo ho etsa hore pampiri e be le phofshoana le phofshoana, kapa ho baka ho peeling ea pampiri e hatisitsoeng. Empa haeba viscosity e nyane haholo, ho bonolo ho e hlahisa
E phaphametseng le e litšila, e tla baka emulsification ea enke maemong a boima, haeba e sitoa ho boloka phetiso e tloaelehileng le phetiso, 'me butle-butle ka enke.
Likaroloana tsa pigment li bokellana holim'a lirolara, lipoleiti tsa khatiso le likobo, 'me ha ho bokellana ho fihla boemong bo itseng, ho tla baka smudging.

Hydroxypropyl methylcellulosee na le mokelikeli o motle haholo, enke ea mokelikeli o loketseng, le ho lekana selibeng sa enke
E na le bokhoni bo botle ba ho kenya le bokhoni bo botle ba ho kenya; phetisetso le phetiso lipakeng tsa lirolara tsa enke kapa lipakeng tsa poleiti ea khatiso le kobo le tsona li ntle;
Lera la enke le tšoana; filimi ea enke e hatisitsoeng e bataletse ebile e boreleli. Haeba mokelikeli o le monyenyane haholo, ho bonolo ho baka ho tsoa ha enke e futsanehileng; kabo e sa lekaneng ea lera la enke, joalo-joalo.
