Hydroxypropypropinyl Methylcelllulolose (HPMC) ke lisebelisoa tsa bohlokoa indasteri ea kaho, haholo-holo lisebelisoa tse thehiloeng ho meeli. Ke ea lelapa la Ethe ea bo-Cellulo Lathe - e sebelisoang haholo e le moemeli oa tokiso ea metsi, 'me ea tlama. Sistimi ea manyetsi, HPMC e sebetsa merero ea mapheoana, ho ntlafatsa mosebetsi, ho ntlafatsa ho tšeha le ho se hanela thepa e lakatsehang sehlahisoa sa ho qetela.
1.Cherical sebopeho le thepa ea hpmc:
HPMC e nkiloe Chololulose, polymer ea tlhaho e fumaneha ka metsing a Cel Pil. Ka ho feto-fetoha ha lintho tsa khemisisi, lihlopha tsa hydroyl li nkeloa sebaka ka lihlopha tsa lithy le tsa hydroxy Tekanyo ea sebaka (DS) le boima ba limolek'hule (MW) ea HPMC Tšusumetso ea HPMC e susumetsa thepa, joalo ka ha ho na le pono, ho boloka metsi le bokhoni ba ho etsa lifilimi. Mabaka ana a ka tsamaisana le litlhoko tse tobileng ea kopo, ho etsa HPMC Khetlo e feto-fetohang ha litlhahiso tsa kaho.
Melao ea lisebelisoa tsa HPMC ka har'a lisebelisoa tsa samente:
Ho Boloka Mebala: HPMC e theha filimi e tšesaane ho potoloha samente ea sistimi, ho fafatsa metsi ka katleho motsoako. Ts'ebetso ena ea thibelo ea nako e telele e tiisa ho fumaneha mongobo o lekaneng oa samahale, e leng le ebisang ho nts'etsopele ea matla a matla le ho fokotseha ha mmele.
Ntlafatso ea ho ntlafatsa: Thepa ea Rheology ea metsoako e mamelloa e bohlokoa hore e be ea bohlokoa le ho beoa. HPMC e sebetsa e le mokhoa oa viscosity, o kenya boitšoaro bo bobe ba pseudoplassic ho ea ho jare. Sena se ntlafatsa ts'ebetso, ho tsamaisa phallo e betere, le homogeneity ha u ntse li fokotsa ho arola le ho tsoa mali.
Phepelo e ntlafalitsoeng: Ka liforomo tsa seretse le konkreite, HPMC e ntlafatsa ho latela lisebelisoa le li-aggregs. Matloana a etsang lifilimi a ho etsa hpmc a theha maqhama le likarolo tse eketsang, li bakoang ke ho hokahanya le ho tšoarella ha thepa e thata.
Ho fokotsa chelete: Lipekere tsa shrinnkage ke tse ngata lisebelisoa tse thehiloeng ho saense, haholo-holo likopahelong tsa tšebetso e phahameng. Ka ho laola mouoane ea metsi le ho laola li-HINDRATER LIPINTIC, ÉMC e thusa ho hlapela shrinkage, ka ho etsa joalo e ntlafatsang sekhobo ka botlalo.
Taolo ea ho beha: HPMC e susumetsa nako ea ho beha nako ea metsoako e tloaetseng ho ikhula kapa ho potlakisa ts'ebetso ea Hydration. Sebaka sena sa thepa se bohlokoa ka likoko tsa kaho moo matla a ka sehloohong a holang a hlokehang, joalo ka teboho ea leholimo kapa ha a sebelisa lingoloa tsa leholimo.
3.Lona ea HPMC ho ea kaho:
Bothata: HPMC e sebelisitsoe haholo ka bokhoni ba seretse bakeng sa mosebetsi oa borikho, lipapatso tsa tale. Bokhoni ba eona ba ho ntlafatsa boikoetliso, hodhesion, ho boloka metsi ho etsa hore e be le lisebelisoa tse bohlokoa ho lipina le boleng bo sa feleng.
Konkreite: Tlalehong ea konkreite, HPMC e sebetsa ho matlafatsa qofutso, fokotsa ho tsoa mali le ho ntlafatsa thepa e qetang. E fumana likopo ho ea konkreite e tloaelehileng le e phahameng-ts'ebetsong e phahameng, e kenya letsoho phihlelong ea thepa eo u e batlang le li-aesthetics tsa eona.
Likhatiso tsa ho iphahamisa: HPMC e bapala karolo ea bohlokoa metsoako e sa tsebeng ho iphahamisa metsoako e sebelisitsoeng bakeng sa ho iphapanya le ho lokisa. Meruti ea eona ea litsi tsa taolo ea lipolotiki e nolofatsa mokhoa oa ho iphahamisa le ho boloka botenya ba junifomo, ho fela ka bongata.
Hangata mekhoa ea ho hlahella le ho qeta (Eifs) Likopi tsena li sireletsa tšusumetso e mpe ea meaho, 'me li ntlafatsa boipiletso bo botle ba mehaho, ba ba etsa khetho e tsebahalang ho etsa mekhoa ea khale ea kaho.
4.Chollenges le maikutlo a tlang:
Ha HpMC e fana ka melemo e mengata lisebelisoa tse amanang le kamano,, ts'ebetso ea eona e ka susumetsoa ke lintho tsa mocheso, mongobo, mongobo o leng mongobo. Ho feta moo, ho boloka le ho hlophisoa hantle ha mefuta ea HPMCC ho ntse ho na le likhopolo tse bohlokoa mabapi le indasteri ea kaho. Boiteko ba kamoso ba kamoso ba ikemiselitse ho nts'etsapele mekhoa e meng e nang le botsoalle le ho ntlafatsa mathata a HPMC ho sebetsana le liphephetso tsena ha a ntse a boloka maemo a ts'ebetso.
Hydroxypropypropinyl Methylcelllulos Litlatsetso tsa eona tsa letšole, ho kenyelletsa le ho boloka metsi, ntlafatso ea ho ikoetlisa, ho fokotsa taolo, ho iphapanya, ho iphahamisa, metsoako ea teboho. Ha isosi ea kaho e ntse e tsoela pele ho fetoha, ho lebeletsoa ka ho ithuta karolo ea bohlokoa ho fihlela libaka tse tšoarellang, tse tšoarellang, tse tšoarellang tse thata.
