Hydroxypropyl Methylcellulose HPMC E3, E5, E6, E15, E50, E4M

Hydroxypropyl Methylcellulose (HPMC) i cellulose ether ine mamakisi akasiyana-siyana, anoratidzwa nemabhii nenhamba. Magiredhi aya anomiririra zvakasiyana-siyana, kusanganisira kusiyana kwehuremu hwemamorekuru, huwandu hwehydroxypropyl, uye viscosity. Heino kupatsanurwa kwemagiredhi eHPMC awataura:

1. HPMC E3:
   • Chiyero ichi chingangoreva HPMC ine viscosity chaiyo 2.4-3.6CPS. Nhamba 3 inoratidza viscosity ye2% yemvura, uye nhamba dzakakwirira dzinowanzo ratidza viscosity yakakwira.
2. HPMC E5:
   • Kufanana neE3, HPMC E5 inomiririra giredhi rakasiyana re viscosity. Nhamba 5 inoratidza viscosity inenge 4.0-6.0 CPS ye 2% aqueous solution.
3. HPMC E6:
   • HPMC E6 imwe mhando ine chimiro chakasiyana che viscosity. Nhamba 6 inoratidza viscosity 4.8-7.2 CPS ye 2% solution.
4. HPMC E15:
   • HPMC E15 ingangove inomiririra giredhi repamusoro rekupenya kana tichienzanisa neE3, E5, kana E6. Nhamba 15 inoratidza kupenya kwe12.0-18.0CPS kwe2% mvura inoyerera, zvichiratidza kusimba kwayo.
5. HPMC E50:
   • HPMC E50 inoratidza giredhi repamusoro rekupenya, nenhamba 50 ichimiririra giredhi re40.0-60.0 CPS remushonga we2%. Gedhi iri ringangodaro rine giredhi repamusoro zvakanyanya kana tichienzanisa neE3, E5, E6, kana E15.
6. HPMC E4m:
   • "M" muE4m inowanzo ratidza huremu hwepakati hwe3200-4800CPS. HPMC E4m inomiririra giredhi rine huremu hwepakati hwehuremu. Inogona kukodzera kushandiswa kunoda kuenzana pakati pekuyerera nekukora.

Pakusarudza giredhi reHPMC rekushandisa kwaro, zvinhu zvinofungwa nezvazvo zvinosanganisira kusimba kwaunoda, kunyungudika, uye zvimwe zvinhu zvinoshanda. HPMC inowanzoshandiswa mumaindasitiri akadai sekuvaka, mishonga, zvizoro, uye chikafu.

Muchikafu, HPMC inowanzoshandiswa sechinhu chinowedzera muzvigadzirwa zvisiri zvemukaka kuti ivandudze hunhu hwakaita sekuchengetedza mvura, kushanda zvakanaka, uye kunamira. Mumishonga nezvizoro, HPMC inoshandiswa nekuda kwehunhu hwayo hwekuumba firimu uye kukora.

Zvakakosha kubvunza mugadziri kana mutengesi kuti uwane ruzivo rwakadzama rwehunyanzvi, kusanganisira zvirevo uye mashandisirwo anokurudzirwa egiredhi rega rega reHPMC. Vagadziri vanowanzopa mapepa eruzivo rwehunyanzvi uye magwaro ezvigadzirwa kuti atungamirire vashandisi mukusarudza giredhi rakakodzera zvavanoda.
