Hydroxypropyl selulose (HPC) ni polymer ikoreshwa cyane mu nganda zitandukanye, harimo imiti, amavuta yo kwisiga, n’ibicuruzwa byita ku muntu.Bikunze gukoreshwa nkibikoresho byiyongera, stabilisateur, firime yahoze, hamwe na viscosity modifier kubera imiterere yihariye.Ariko, mugihe muganira kuri solve kuri HPC, ni ngombwa kumenya ko ibiranga ibisubizo byayo biterwa nimpamvu nkurwego rwo gusimbuza (DS), uburemere bwa molekile, hamwe na sisitemu yo gukoresha ikoreshwa.Reka twinjire cyane mumiterere ya HPC, imyitwarire yayo yo kwikemurira ibibazo, hamwe numuti utandukanye ukoreshwa nayo.
Intangiriro kuri Hydroxypropyl Cellulose (HPC):
Hydroxypropyl selile ni inkomoko ya selile, aho amatsinda ya hydroxypropyl asimbuzwa umugongo wa selile.Ihinduka rihindura imiterere yaryo, bigatuma irushaho gushonga mumashanyarazi amwe ugereranije na selile kavukire.Urwego rwo gusimbuza rugira ingaruka ku gukemuka, hamwe na DS yo hejuru bigatuma habaho gukemura neza mumashanyarazi adafite inkingi.
Ibiranga ibisubizo:
Ubushobozi bwa HPC buratandukana bitewe na sisitemu ya solvent, ubushyuhe, urugero rwo gusimbuza, hamwe nuburemere bwa molekile.Mubisanzwe, HPC yerekana gukemura neza mumashanyarazi yombi.Hasi hari ibishishwa bisanzwe bikoreshwa mugusenya HPC:
Amazi: HPC yerekana imbaraga nke mumazi bitewe na hydrophobique.Nyamara, amanota mabi ya HPC afite agaciro ka DS yo hasi arashobora gushonga byoroshye mumazi akonje, mugihe amanota yo hejuru ya DS ashobora gusaba ubushyuhe bwo hejuru kugirango asenywe.
Inzoga: Inzoga nka Ethanol na isopropanol zikoreshwa cyane mumashanyarazi ya HPC.Nibishishwa bya polar kandi birashobora gushonga neza HPC, bigatuma bikenerwa mubikorwa bitandukanye.
Chlorine Solvents: Umuti nka chloroform na dichloromethane ufite akamaro mu gushonga HPC bitewe nubushobozi bwabo bwo guhagarika hydrogene ihuza iminyururu ya polymer.
Ketone: Ketone nka acetone na methyl etyl ketone (MEK) nayo ikoreshwa muguhagarika HPC.Zitanga ibisubizo byiza kandi akenshi zikoreshwa mugutwikira no gufatira hamwe.
Esters: Esters nka Ethyl acetate na butyl acetate irashobora gushonga HPC neza, itanga uburinganire bwiza hagati yo gukomera no guhindagurika.
Hydrocarbone ya Aromatic: Umuyoboro wa Aromatic nka toluene na xylene ukoreshwa muguhagarika HPC, cyane cyane mubisabwa aho bikenewe cyane.
Glycols: Ethers ya Glycol nka etylene glycol monobutyl ether (EGBE) na propylene glycol monomethyl ether acetate (PGMEA) irashobora gushonga HPC kandi akenshi ikoreshwa ifatanije nindi mashanyarazi kugirango ihindure ubukonje nibiranga byumye.
Ibintu bigira ingaruka kubikemura:
Impamyabumenyi yo Gusimbuza (DS): Indangagaciro za DS zisanzwe zongera imbaraga zo gukemura nkuko byongera hydrophilicity ya polymer.
Uburemere bwa molekuline: Uburemere buke bwa molekile ya HPC ikunda gushonga byoroshye ugereranije nuburemere buremereye bwa molekile.
Ubushyuhe: Ubushyuhe bwo hejuru burashobora kunoza ubukana bwa HPC, cyane cyane mumazi nandi mashanyarazi.
Porogaramu:
Imiti ya farumasi: HPC ikoreshwa muburyo bwa farumasi nkibihuza, bidahwitse, kandi bikomeza-kurekura.
Ibicuruzwa byawe bwite: Bikoreshwa mubicuruzwa bitandukanye byita kumuntu nka shampo, amavuta yo kwisiga, hamwe na cream nkibyimbye na stabilisateur.
Inganda zikora inganda: HPC ikoreshwa muburyo bwo gutwikira kugirango igabanye ububobere no kunoza imiterere ya firime.
Inganda z’ibiribwa: Mu nganda z’ibiribwa, HPC ikoreshwa nkibintu byiyongera kandi bigahinduka mubicuruzwa nka sosi no kwambara.
Hydroxypropyl selulose ni polymer itandukanye hamwe nurwego runini rwa porogaramu.Ibiranga solubilité ituma bihuza na sisitemu zitandukanye zo gukemura, bigafasha gukoreshwa mubikorwa bitandukanye.Gusobanukirwa imyitwarire yo gukemura ya HPC ningirakamaro mugutegura ibicuruzwa byiza no kunoza uburyo bwo gutunganya.Muguhitamo igisubizo gikwiye no gusuzuma ibintu nka DS nuburemere bwa molekuline, ababikora barashobora gukoresha neza HPC kugirango bagere kubikorwa byifuzwa.
