Hydroxyprusyl methyl cellelose ether (HPMC)

Zvimiro:
① Nekuchengetwa kwakanaka kwemvura, kuremedza, rheology uye kuderedza, ndiyo yekutanga sarudzo yezvinyorwa zvekuvandudza kunaka kwezvinhu zvekuvaka uye zvekushongedza zvinhu.
②Pe renji rekushandisa: Nekuda kwekupedzisa mamakisi, inogona kuiswa kune ese eupfu ekuvaka zvinhu. 
③small dosage: 2-3 kg per toni yeupfu hwekuvaka yekuvaka nekuda kwemhando yepamusoro.
④ Yakanaka kupisa kudziya: Iyo mvura yekuchengetwa kwemvura yehuwandu hweHPMC zvigadzirwa zvichaderera nekuwedzera kwekushisa. Mukupesana, zvigadzirwa zvedu zvinogona kuita kuti dondo rive nemvura yepamusoro yekuchengetedza mvura kana tembiricha ichisvika 30-40 ° c. Kugadziridzwa kwemvura kwakasimba kunyangwe pakupisa kwakanyanya kwemaawa makumi mana nemasere.
⑤Good Solubility: Pamhepo tembiricha, wedzera mvura uye kumutsa kwemaminitsi mashanu, regai igare kwemaminitsi mashoma, uye wozoomutsa kunyungudika. Dissolution inokurudzirwa kuPH8-10. Mhinduro yacho yakaiswa kwenguva yakareba uye ine kugadzikana kwakanaka. Muzvisanganiswa zvakaoma, kumhanya kwekuparadzira uye kunyungudutsira mumvura kwakanyanya kunaka.

Basa reHPMC mune yakaoma Powder Dorar

Mune yakaoma poda poda dowar, methyl cellulose ether inoda basa rekuchengeta mvura, kuremedza uye kugadzirisa maitiro ekuvaka. Yakanaka mvura yekuchengetedza inovimbisa kuti motsi haizo kukonzera sanding, poda uye kuderedza simba nekuda kwekushomeka kwemvura uye isina kukwana yeComent hydration; Iko kukonzeresa simba rinowedzera zvakanyanya simba rekusimba kwemutema, uye kuwedzera methyl cell

Kazhinji, iyo yepamusoro viscosity, iri nani kuchengetedza kwemvura. Nekudaro, yakakwira viscosity, yakakwira iyo smecular uremu hweMC, uye iyo solubility ichave yakaderedzwa, iyo inogona kuve nekukanganisa kusasimba kwekusimba uye kwekuvaka kwemutya. Yakakwira iyo viscosity, zvakanyatsojeka zvinokanganisa mudhaka, asi haina hukama zvakananga. Iyo yepamusoro viscosity, iyo yakawanda viscous iyo dari yakanyorova ichave. Munguva yekuvakwa, inoratidzwa sekunamatira kune iyo scriper uye yakanyanya kuderera kune substrate. Asi hazvibatsiri kuwedzera simba rekuumbwa kweiyo yakanyorova dhaka pacharo.

Zvivakwa zvemuviri uye zvemakemikari:

1. Chitarisiko: chena kana kubva-chena poda.
2. 80 mesh pass pass rate ndeye 100%.
3. Karbonization tembiricha: 280-300 ° C
4. "
5. Kudzvinyirira tembiricha: 190-200 ° C.
6. Kumwe kushushikana: 2% mhinduro mhinduro ndeye 42-56dyn / cm3.
7. Nyorovesa mumvura uye mamwe masosi, senge ethanol / mvura, propaniol / mvura, trichloroethane, nezvimwewo zvakakodzera. Mhinduro dzemvura dziri pamusoro inoshanda. Yakakura transparency uye yakagadzikana kuita. Zvakatemwa zvakasiyana zvezvigadzirwa zvine akasiyana tembiricha yeGel, uye iyo solubility inoshandura neViscosity. Iyo yakadzika viscosity, iyo yakakura solubility. Zvimiro zvakasiyana zveHPMC zvine mamwe mutsauko mukuita, uye kupaza kweHPMC mumvura hakuna kukanganiswa neiyo pH kukosha.

9. HPMC zvakare ine hunhu hwekukakavara, kupokana kwemunyu, kugadzikana kwemvura, kugadzikana kwemvura, kuumbwa kwemvura, uye huwandu hwenzasi hwekurwisa enzyme, kupararira uye kuriparadzana.

Chinangwa chikuru:

1. Indasitiri yekuvaka: Sechiratidziro-chekuchengetedza mvura uye kudzoreredzwa kweiyo siment frar, inogona kuita kuti dorari rinopukuta. Inoshandiswa senge binder mu plaster, plaster, putty poda kana zvimwe zvigadzirwa zvekuvakisa kuti uvandudze nguva yekuvandudza uye yekuwedzera nguva yebasa. Inogona kushandiswa seane namatira tile, marble, kushongedza kwepurasitiki, paste kusimbisa, uye kunogona kudzikisa huwandu hwesimendi. Kuita Kwemvura-Kuchengetedza KweHpmC kunotadzisa iyo slurry kubva pakupaza nekuda kwekuomesa nekukurumidza mushure mekushandisa, uye nekuwedzera simba mushure mekuomesa.
2. Ceramic Kugadzira Indasitiri: Inoshandiswa zvakanyanya sechigadzirwa mugadzirwa yeCeramic zvigadzirwa.
3. Kubatanidza Indasitiri: Inoshandiswa seyekani, kuparadzira uye stabilizer muindasitiri inovhara, uye ine yakanakira mumvura kana organic sol sol. Inogona kushandiswa mune pendi remover.
4
5. Plastiki: Inoshandiswa seyakagadzirwa kuburitsa mumiriri, softener, lubricant, nezvimwe.
6
7. Vamwe: Ichi chigadzirwa chinowanzoshandiswa zvakanyanya mumatehwe, zvigadzirwa zvepepa, michero uye michero yekuchengetedza uye machira ezvinyorwa.

Maitiro ekunyungudika uye kushandisa:

1
2. Gadzira porridge-saamai doro: Chekutanga ita HPMC Mai Lifeor neKwakakwira Simba (Iyo nzira yakafanana pamusoro pekutsvedza), wedzera mvura inotonhorera uye gadzira mvura inotonhora uye enderera uchimutsa kusvikira aongorora kusvika pachena.

Kurongedza, kuchengetwa uye zvekufambisa zvekuchenjera:

Akarongedzwa mupepa mapepa epurasitiki kana makadhibhodi maruva akamhara nePolyethylene mapurasitiki mabhegi, ur uremu hwebhegi: 25kg. Yakavanzika yekuchengetedza. Dzivirira kubva kuzuva, mvura uye unyoro panguva yekuchengetera uye kufambisa.
