HPMC (HYDROXYPROPYL MetHylcellose) ihimoni uye stabilizer inowanzo shandiswa mune zvekuvaka, majasi, mishonga uye chikafu. HPMC 15 CPS zvinoreva kuti viscosity yayo ndeye gumi neshanu centpoise, iyo iri yakaderera viscosity giredhi.
1. Wedzera HPMC yekushambadzira
Nzira yakatwasuka uye inoshanda yekuwedzera iyo viscosity yeHPMC ndeyekuwedzera kuwanda kwayo mumhinduro. Kana chikamu chikuru cheHPMC chinowedzera, iwo wisiko mhinduro yacho inowedzerawo. Iyo yakakosha yenzira iyi ndeyekuti HPMC inowedzera iyo visikoka yeiyo mhinduro nekugadzira matatu-matatu-dimensional network network. Sezvo huwandu hweHPMC mamorekuru mumhinduro inowedzera, dentity uye simba reiyo network mitekineti inowedzerawo, nekudaro ichiwedzera visikopa yemhinduro. Nekudaro, pane muganho wekuwedzera kusunganidzwa. Kunyanya kukwira kusungirirwa kweHPMC kuchaita kuti manyorero gadziriro yekudzikira, uye inogona kukanganisa mashandiro ayo mune zvakanyatso mafaro, akadai sekuvaka uye kuwanda.
2. Dzora tembiricha yemhinduro
Tembiricha ine pesvedzero huru pane iyo solubility uye viscosity yeHPMC. Pakudziya kwakadzika, iyo visikopa yeHPMC mhinduro yakakwira; Ndichiri pakupisa kwakakwirira, iyo viscosity yeHPMC Soluol mhinduro ichaderera. Naizvozvo, kuderedza tembiricha yemhinduro yakakodzera panguva yekushandisa kunogona kuwedzera viscosity yeHPMC. Inofanira kucherechedzwa kuti iyo solubility yeHPMC mumhinduro yakasiyana pakupisa kwakasiyana. Zvinowanzoitika nyore kuparadzira mumvura inotonhora, asi zvinotora imwe nguva yenguva yekunyungudika. Inopaza nekukurumidza mumvura inodziya, asi viscosity yakaderera.
3. Chinja iyo pH kukosha kweiyo solvent
Iyo viscosity yeHPMC iri zvakare inoteerera kune iyo PH Kukosha kweiyo mhinduro. Mumamiriro ezvinhu asina kwavakarerekera kana zviri pedyo, iyo viscosity yeHPMC mhinduro ndiyo yepamusoro. Kana iyo pH Kukosha kweiyo mhinduro inotsauka kubva kusarerekera, iyo visikoity inogona kuderera. Naizvozvo, visikopa yeHPMC mhinduro inogona kuwedzerwa nekugadzirisa zvakanyatso kugadziriswa iyo pH Kukosha kweiyo mhinduro (semuenzaniso, nekuwedzera buffer kana acid-base reulator). Nekudaro, mukushanda chaiko, kugadziriswa kweiyo ph kukosha kunofanirwa kunge kuchenjera kwazvo, nekuti shanduko huru dzinogona kukonzera hpmc kusvibiswa kana kuita kwekuita.
4. Sarudza yakakodzera solvent
Iyo solubility uye viscosity yeHPMC mune dzakasiyana solvent system dzakasiyana. Kunyangwe HPMC inonyanya kushandiswa mumvura mhinduro, iyo ethanol solvent (isopropanol, etc.) kana akasiyana masango anogona kuchinja mutariri weiyo HPMC Molecule, nokudaro anokanganisa viscosity. Semuenzaniso, chidiki chidiki chesimba solvent inogona kuderedza kupindira kwemamolecules yemvura paHPMC, nekudaro inowedzera iyo visikopa yemhinduro. Mune chaiyo mashandiro, zvinodikanwa kusarudza yakakodzera organic solses zvinoenderana nekunyorwa chaiko.
5. Shandisa AIDHINGING AIDS
Mune zvimwe zviitiko, mamwe marudzi ezvigadzirwa anogona kuwedzerwa kune HPMC kuti izadzise mhedzisiro yekuwedzera viscosity. Kazhinji inoshandiswa wakakora AIDS Semuenzaniso, Xanthan Gum inzvimbo yechisikigo polysaccharari ine yakasimba yakasimba mhedzisiro. Kana ichishandiswa neHPMC, iyo maviri inogona kuumba synergistic mhedzisiro uye inowedzera zvakanyanya kuwedzera zvevisiko yehurongwa.
6. Chinja degree rekutsiva hpmc
Iyo viscosity yeHPMC inoenderana neiyo degree rekutsiva kwenzira yayo uye hydroxyprupoxy mapoka. Dhigirii rekutsiva rinobata iyo solubility uye iyo viscosity yemhinduro. Nekusarudza HPMC ine madhigirii akasiyana ekutsiva, iwo wiscosity mhinduro inogona kugadziriswa. Kana iyo yepamusoro viscosity HPMC inodiwa, chigadzirwa chine nzira yakakwira inogona kusarudzwa, nekuti iyo nzira yepamusoro yezvinhu, iyo yakasimba iyo hydrophobiligity yeHPMC, uye iyo visikophole mushure mekunyungudika.
7. Wedzera nguva yekunyungudika
Iyo nguva panguva iyo HPMC LELSOLVES ichakanganisa zvakare viscosity yayo. Kana HPMC isina kunyungudutswa zvachose, iyo viscosity yemhinduro haisvike iyo yakakodzera mamiriro. Naizvozvo, nenzira yakakodzera kuyamwisa nguva yeHPMC mumvura kuti ive nechokwadi chekuti HPMC yakanyatso nyonganiswa inowedzera zvinowedzera kuwanda kwemhinduro yemhinduro yayo. Kunyanya kana kupera simba pakudziya kwakaderera, iyo HPMC Dissolution yekudzvinyirira inogona kunonoka, uye kutambanudza nguva yakakosha.
8. Chinja Shear Mamiriro ezvinhu
Iyo viscosity yeHPMC inoenderana zvakare neyechivande simba rinoiswa pasi pekushandisa. Pasi pemamiriro ekunze akareba, iwo mavhesi eHPMC mhinduro ichaderera kwenguva pfupi, asi kana Shear riregedza, visikoka ichapora. Zvekuita maficha ayo anowana kuwedzera viscosity, isimba raSearari iro mhinduro yacho inogona kuderedzwa, kana inogona kushanda pasi pemamiriro ezvinhu akaderera ekuchengetedza yakakwirira viscosity.
9. Sarudza iyo yakakodzera molecular uremu
Uremu hwehurume hweHPMC zvakananga zvinobata zvavakaita zvavakaita. HPMC ine yakakura molecular uremu inoumba yakakura network network mamiriro mune mhinduro, zvichikonzera kusimba yepamusoro. Kana iwe uchifanira kuwedzera iyo viscosity yeHPMC, unogona kusarudza HPMC zvigadzirwa zvine uremu hwepamusoro. Kunyangwe HPMC 15 CPS ichi chigadzirwa chakaderera, iyo viscosity inogona kuwedzerwa nekusarudza yakakwira-molecular-suremu-uremu mumhando yakafanana nechigadzirwa chimwe chete.
10. Funga nezvezvakatipoteredza zvinhu
Zvinhu zvemhoteredzo zvakadai sekusimira uye kudzvanywa zvinogona zvakare kuve neyakaoverana kweiyo viscosity yeHPMC Solution. Mune imwe nzvimbo yakakwirira yekuzvininipisa, HPMC inogona kutora nyoro kubva kumhepo, ichikonzera zvavakaita kuti zvideredze. Kuti udzivise izvi, mamiriro ekunze ekugadzira kana kushandisa nzvimbo inogona kudzorwa zvakanaka kuti iite nharaunda yakaoma uye nekumanikidzwa kwakakodzera kuchengetedza iyo yeHPMC solution.
Kune nzira dzakawanda dzekuwedzera iyo viscosity yeHPMC solution yeHPMC, inosanganisira kuwedzera kusungwa, kugadzirisa tembiricha yekutsiva uye kusarudza huremu uye etc. iyo nzira chaiyo kuti isarudzwe zvinoenderana nekunyorera chaiko mamiriro ezvinhu uye kugadzirisa zvinodiwa. Mukushanda chaiko, zvinowanzo kuve wakakodzera kuti uongorore zvinhu zvakawanda uye gadzirisa zvine musoro uye zvakaringana kuti uve nechokwadi chekugadzirisa kweHPMC mune chaiyo application.
