Hydmer Polymer PydroxypropyLe Methylcellll

Hydroxypropypropypropinyl Methylcelll. E ka sebelisoa e le moemeli oa metsi a phomolo, thickener le ho tlama ho ntlafatsa ts'ebetso ea li-plakhasi tse thehiloeng tsa nakoana.

HPMC ke semina sa maiketsetso, polymer-polymer e qhibilihileng e entsoeng ka cellulose. E nkiloe ho contleluble ea tlhaho ka ts'ebetso ea ho fetola lik'hemik'hale e kenyelletsang kenyelletso ea hydroxypropyl le lihlopha tsa methyl. Phetoho ena e baka koluoa ​​e nang le qubu e ntlafalitsoeng, botsitso ba ho futhumatsa le ho hanyetsa ka lik'hemik'hale.

Ts'ebeliso ea HPMC ka liforomo tsa polasetiki e fanang ka melemo e mengata joalo ka:

  1. Ho ntlafatsoa ho ntlafalitsoeng: HPMC e sebetsa e le mosebeletsi oa Rheology e ntlafatsang ho ba le matla le thepa ea pokello ea li-parter. Ho eketsa ho tšeha, ho bokolla le ho jala ha lehlaka, ho le lumella ho sebelisoa habonolo ho substrate.
  2. Hloekisa Metsi: HPMC e ka monya le metsi a mangata, a thusang ho thibela lebone ho tsoa kapele haholo. Sebaka sena se boetse se etsa bonnete ba hore setter se boloka se feto-fetohe le ho ntlafatsa nako e telele, esita le maemong a chesang le a omileng.
  3. Ho eketseha hoa ho eketseha le hodhesion: HPMC e theha filimi e potolohileng mokokotlo, e ntlafatsang tšebelisano ea bona le ho tšoarella ho substrate. Sebaka sena se tiisa hore samente e lula e tiile ebile e se ke ea senya kapa e arohaneng le substrate.
  4. Ho fokotsoa: HPMC e ntlafatsa matla le ho feto-fetoha ha ntoa ea lehlaka, ho fokotsa menyetla ea ho hlapela ka lebaka la ho thefula kapa ho holisa.
  5. Ho Lokela ho Leba: HPMC e fana ka polasetiki ka khanyetso e ntlafalitsoeng ea metsi le lik'hemik'hale tse ntlafalitsoeng le lik'hemik'hale, li etsa hore e tšoarelle le ho loants'oa ke ho ikhetholla le ho tsofala.

Ntle le melemo ena, HPMC le eona e kenyelelitsoe ka mokhoa o tsitsitseng le ea tikoloho e ka u thusang ho fokotsa phello ea li-plaster tse thehiloeng tikoloho e thehiloeng. Ha se chefo e nang le chefo, e tsamaisoang hantle, ebile ha e lokolle lintho tse kotsi tikolohong.

Ho sebelisa HPMC ho li-plats tse thehiloeng ho saense, hangata ke ho ekelletsa moeli o omileng oa samente le lehlabathe pele ho tlatsetso. Tekanyetso e khothalelitsoeng ea HPMC e fapana ho latela kopo e khethehileng le thepa eo e neng e se e lakatseha ea Plaster. Ka kakaretso, litekanyetso tsa 0.2% ho isa ho 0.5% ea HPMC ho ipapisitse le boima ba samente le lehlabatheng li khothalelitsoe.

HPMC ke e fapaneng le ea sebetsang e ka ntlafatsang haholo ts'ebetso ea li-plalls tse thehiloeng ho saense. Boemong ba eona ba tlhaho, ho tsitsa, le botsoalle le eco bo etsa hore ke khetho e ntle bakeng sa likonteraka tsa meralo ea litloaelo tsa 'mele.
