Basa re hydroxyprupyl methylcellose mune putty

HydroxyPropyl methylcellose (HPMC) ishandai yenhengo uye inopesana polymer inoita basa rakasiyana siyana mune dzakasiyana siyana dzekushandisa, kusanganisira putty mafomu. Putty chinhu chinowanzoshandiswa pakuvaka uye dzakasiyana-siyana maindasitiri ekuzadza, kuisimbisa uye zvinonyadzisa.

1. Kuongorora kwehydroxyprupyl methylcellose (HPMC):

Hydroxypropylmethylcylsellose is a cellulose derivative synthesised kubva kuCellulose, polymer yakasikwa inowanikwa mumasero emasero. Maitiro ekugadzira anosanganisira kurapa cellulose neAlkalis uye eraliting vamiririri. Iyo inokonzeresa HPMC ndeyechena kana kubva pane chena-chena poda iyo inonyudza mumvura uye inoumba iyo yeTranspent Viscous Solution.

2. Zvivakwa zve hydroxyprupyl methylcellose:

Usati waongorora basa reHPMC muPutty, zvinodikanwa kuti unzwisise zvakakosha zvivakwa zveHPMC:

Solubl Solubility: HPMC iri svutugadzike uye inoumba mhinduro yakajeka uye yakagadzikana kana ikasanganiswa nemvura. Ichi chivakwa chinobata chinozadzisa iyo yaunoda kusawirirana muPutty mafomu.

Thermal Gelation: HPMC inoenda kune inochinja-chinja ermal gelation maitiro, zvinoreva kuti viscoity yayo inowedzera kana ichipiswa uye kuderera kana ichidonha. Iyi pfuma yakakosha muPutty application iyo shanduko tembiricha inogona kuitika panguva yekusanganisa uye kushandisa.

Film Fomu: HPMC inoumba firimu rakatetepa, rinochinjika kana rakaiswa kune pasi. Ichi chivakwa chinopa kudenhana kwe putty uye kubatana, kusimudzira mashandiro ayo seyakagadzirirwa kurapwa.

Thickener: HPMC zviito seanoshanda samaki, ichipa iyo inodiwa viscosity uye kuwirirana kune putty mafomu. Inodzorwa inoshungurudza simba rinopararira nyore nyore uye smoothes nzvimbo.

3. Basa re hydroxyprupyl methylcellose muPutty:

Yakavandudzwa Workability: HPMC inosimudzira kushanda kweiyo putty nekuisa chimiro chakanyorova uye chine plappia. Kudzora kwakasimba uye kwemvura kuchengetwa kwemvura kunofambisa chikumbiro uye kupararira kweiyo putty pane dzakasiyana siyana nzvimbo.

Kuchengetwa kwemvura: imwe yemabasa akakosha eHPMC muPutty mafomu ndeye kugona kwayo kuchengetedza mvura. Iyi ficha inodzivirira iyo putty kubva pakuomesa zvachose, ichivimbisa nguva yakakwana yekushandisa, kuumba uye kupedzisa. Kugadziridzwa kwemvura kunobatsirawo kununura kushamisika uye kusungira zvinhu.

ADHESION uye kubatana: HPMC inosimudzira kusimudzira nekuumba firimu rakatetepa pamusoro peiyo substrate, inosimudzira chisungo pakati peiyo putty uye zvinhu zviri pasi pechinhu. Uye zvakare, iyo midziyo yekubatira yeHPMC inobatsira kuvandudza simba rose uye kujaira kwekutyisa mushure mekushandisa.

Deredza Shrinkage: Shrinkage idambudziko rakajairika mune putty mafomu uye rinogona kukonzera marara uye kusakwana mumusoro. HPMC inobatsira kuderedza kuderedza nekudzora kwemvura kubuda kwemvura panguva yekuomesa maitiro, zvichikonzera kuwanda kwakasimba kunonyanya kuramba kupokana.

Yakavandudzwa nguva yakatarwa: Iyo yekukanda majecha yeHPMC inogona kudzora iyo nguva yakatarwa mune zvekupfeka mafomu. Izvi zvakakosha kune zvekushandisa uko imwe nguva yenguva inodiwa kuti utya hwakatisa uye kurapa.

4. Zvakanakira kushandisa hydroxyprupyl methylcellose muPutty:

Kuedza: HPMC inogona kuiswa mune dzakasiyana siyana dzekutyisa mafomu, zvichiita kuti zviite kuti zviite zvakasiyana-siyana zvikumbiro zvakasiyana semadziro putty, huni

Kuvandudzwa Durability: HPMC's Zvinonamatira zvivakwa zvinopa kujaira kwenguva refu uye kuita kwekutyisa, kuderedza mukana wekupwanya uye kuremara nekufamba kwenguva.

Kuenderana nedzimwe zvinowedzera: HPMC inoenderana nehuwandu hwekuwedzera uye mafirita anowanzoshandiswa mune putty mafomu, achibvumira kugadziriswa kune chaiyo maitiro ekuita.

Kufunga nezvemamiriro ekunze: Semutengo weCellulose Desivative, HPMC inowanzoonekwa seyakaishamwaridzana. Iyo biodegradable uye haina kukonzera kusvibiswa kwakakosha kune zvakatipoteredza.

5. Zvikumbiro kunze kwekutya:

Indasitiri yekuvaka: Kuwedzera kuPutty, HPMC inoshandiswa zvakanyanya mumidziyo yekuvaka dzakasiyana siyana, kusanganisira motokari, inonamira kuomerera, kubatsira kuvandudza basa, kudzivirirwa kwemvura uye kusimba kwemvura.

Pharmaceuticals: HPMC inoshandiswa seyekuchinjika, kuparadzaniswa uye firimu kuunganidza mumiririri mune mishonga yemishonga nekuda kwezvinhu zvaro uye zvakadzorwa kuburitswa.

Indasitiri yeChikafu: Muindasitiri yekudya, HPMC inoshandiswa sedhizimusi, stabilizer uye emulsifier mune zvigadzirwa senge sosi, zveshuwa uye zvakabikwa zvinhu.

6. Mhedziso:

Hydroxyprospropyl methylcellose inzvimbo inoverengeka polymer iyo inoita basa rinokosha mukuumbwa. Zvivakwa zvaro zvakasarudzika, kusanganisira zvemvura solubility, mafuta ekunyora uye mafirimu-ekugadzira mafirimu ekugadzira, batsira kuvandudza basa, kuderedza uye kusimba kwekutyisa. Sechikamu chakakosha chezvinhu zvekuvakisa, HPMC inoenderera mberi nekutsvaga zvikumbiro zvakazara mumatambudziko akasiyana-siyana, kuratidza kuwanda kukuru uye kukosha mukuita kwemazuva ano uye zvekuvakisa maitiro. Kuenderera mberi kwekutsvaga uye kusimudzira mumunda wePolymer Science kunogona kutungamira kune dzimwe nzvimbo dzinozowedzera huwandu hwenzvimbo dzemberi dze hydroxyproproplulose.
