HydroxyPropyl methylcellose (HPMC) ndeyekuchinja kwakawanda kunoshandiswa zvakanyanya mukuvaka, mishonga, chikafu uye imwe minda. Iyo ine yakanaka yakanaka, firimu-inogadzira, inosimbisa uye inoisa zvivakwa. Iyo chaiyo yekusanganisa nzira yakakosha kuve nechokwadi chekuita kwayo uye zvigadzirwa zvechigadzirwa.
1. Kugadzirira
Kugadzirira kwezvinhu: Ita shuwa yekushandisa yakakwira-mhando HPMC poda. Sarudza iyo yakakodzera viscosity uye yakatarwa zvichienderana nekunyorwa chaiko.
Zvigadzirwa zvekugadzirira: Yakakwira-kumhanya Mixer, kupararira kana kujairika mijama inowanzo kushandiswa. Midziyo inofanirwa kuve yakachena uye isina kusvibiswa.
Solvent Sarudzo: HPMC inowanzo kuvezwa mumvura inotonhora, asi organic sol solvent kana imwe midhiya inogona zvakare kushandiswa mune zvimwe zviitiko. Kusarudza iyo chaiyo solvent yakakosha pakusanganisa mhedzisiro uye kuita kwechigadzirwa chekupedzisira.
2. Kusanganisa matanho
Kufungisisa: HPMC Powder inofanira kunge iri pre-yakaongororwa kuti ibvise mapundu uye kusvibiswa kuve nechokwadi chekupararira yunifomu.
Solvent Everent:
Yakatonhora Mvura Kupararira nzira: Dururira iyo inodiwa huwandu hwemvura inotonhora mumuunzi, tanga kusimudzira, uye zvishoma nezvishoma wedzera hpmc poda. Dzivisa kuwedzera zvakawandisa panguva imwe chete kuti udzivise Agglomeration. Ramba uchimutsa kusvikira hupfu hwakazara zvachose.
Mvura inopisa yekuparadzira nzira: Sanganisa HPMC poda nemvura inotonhora kuti iite kumiswa, uye wozodururira mumvura inopisa yakanangana ne 70-90 ° C. Simbisa kumusoro kwekumhanyisa kunyungudika, wobva wawedzera mvura inotonhorera kuti itonhore kumhepo tembiricha kuti uwane mhinduro yekupedzisira.
Kupaza uye kwakasimba:
HpMC yanyungudutswa mumvura, kumiswa kunotangwa. Sezvo nguva yekukurudzira inowedzera uye tembiricha inoderera, iyo visikoka zvishoma nezvishoma inowedzera kusvikira yanyungudika zvachose. Nguva yekunyungudika inowanzoita maminitsi makumi matatu kusvika maawa akati wandei, zvichienderana neiyo viscosity uye kusunganidzwa kweHPMC.
Kuve nechokwadi chekupazwa kwakazara, mhinduro yacho inogona kubvumidzwa kumira kwenguva yakati (yakadai seyomarara) kuti uwane iyo yakakwana viscosity.
Kugadziriswa uye kugadzirisa:
Kana zvichidikanwa, zvivakwa zvemhinduro zvinogona kugadziridzwa nekuwedzera zvimwe zvinoshandiswa (zvakadai seanochengetedza, thickeners, nezvimwewo). Kuwedzera kunofanirwa kuitwa zvishoma nezvishoma uye kuve nechokwadi chekuparadzirwa kwounifomu.
Filt uye defoaming:
Kubvisa zvimedu zvisina musoro uye nemhepo mabhuru, firita kana degasser inogona kushandiswa. Filtoration inogona kubvisa tsvina, nepo deglowing inobatsira kuwana mhinduro yakagadzikana.
3. Kuchera
Hunhu hwemvura uye tembiricha Zvinokurudzirwa kushandisa mvura nyoro kana kuti yakadhindwa mvura kuti dzidzivise Greencium uye maganium ions mumvura yakaoma. Yakanyanya kukwirira kana yakanyanya kuderera tembiricha inokanganisa iyo solubility uye yakakora mhedzisiro yeHPMC uye inofanirwa kudzorwa mukati meiyo yakakodzera mhando.
Kukurudzira kumhanya uye nguva: yakanyanya kukwirisa kumhanya kunomhanyisa kunogona kuunza huwandu hwakawanda hwemhepo uye fomu mabhuru; Kunyanya kuderera kumhanya kunomhanyisa kunogona kukonzera kusanganisa kusingaenzaniswi. Iyo inomutsa paramita inofanira kugadziriswa zvinoenderana nemidziyo chaiyo uye formula.
Dzivirira Agglomeration: Kana uchiwedzera HPMC poda, inofanirwa kuwedzerwa zvishoma nezvishoma uye zvakaringana, uye zvichichengetwa zvichimutsa kudzivirira kuumbwa kwegglomerates. Iyo hupfu inogona kuve yakavezwa nemvura inotonhora kana iyo anti-caking agent inogona kushandiswa.
Kuchengetera uye Shandisa: Iyo yakagadzirirwa HPMC mhinduro inofanira kuchengetwa mumudziyo wakavharwa kuti udzivise mwenje uye kupisa kwakanyanya. Kana yakachengetwa kwenguva yakareba, iyo mhinduro yenyika inofanira kutariswa nguva zhinji kuti udzivise kufungidzira kana kuora.
Kusanganisa hydroxypropyl methylcellose inoda nzira yakasimba yekudzora uye mashandiro ekushandisa kuti ave nechokwadi chekuita kwayo uye mhedzisiro mune yekupedzisira chigadzirwa. Kuburikidza neiyo sarudzo yekushandisa, solvent kushandiswa, nzira yekusanganisa uye nzira dzekudzivirira, yakakwirira-mhando HPMC mhinduro inogona kugadzirira kuzadzisa zvinodiwa munzvimbo dzakasiyana dzekushandisa. Mukushanda chaiko, kugadzirisa uye fungidziro kunofanirwa kuitwa maererano nemamiriro ezvinhu chaiwo kuti awane mukana wakanakisa.
