Hydroxypropyl Methyl Cellulose Ether (HPMC)

Features:
① Nekuchengetwa kwemvura kwakanaka, kukora, rheology uye kunamatira, ndiyo yekutanga sarudzo mbishi yekuvandudza kunaka kwezvinhu zvekuvaka uye zvekushongedza.
②Kusiyana kwakasiyana kwekushandisa: nekuda kwemagiredhi akazara, inogona kuiswa kune zvese zvehupfu zvekuvaka. 
③Diki dosage: 2-3 kg patani yehupfu zvekuvakisa nekuda kwemhando yepamusoro.
④ Yakanaka kupisa tembiricha kuramba: mwero wekuchengetedza mvura wezvakajairwa HPMC zvigadzirwa zvinodzikira nekuwedzera kwekushisa. Kusiyana neizvi, zvigadzirwa zvedu zvinogona kuita kuti dhaka rive nehuwandu hwekuchengetedza mvura kana tembiricha yasvika 30-40 ° C. Kuchengetedzwa kwemvura kwakagadzikana kunyange pakupisa kwakanyanya kwemaawa makumi mana nemasere.
⑤Kunyungudika kwakanaka: patembiricha yemumba, wedzera mvura uye kurunga kwemaminetsi angangoita mashanu, rega igare kwemaminetsi mashoma, wozosimudzira kunyungudika. Dissolution inokwidziridzwa paPH8-10. Mhinduro yacho inoiswa kwenguva yakareba uye ine kugadzikana kwakanaka. Mumisanganiswa yakaoma zvinhu, kukurumidza kwekuparadzira uye kunyunguduka mumvura kunonyanya kunaka.

Basa reHPMC muvhu rakaoma dhaka

Mune yakaoma poda dhaka, methyl cellulose ether inotamba basa rekuchengetedza mvura, kukora nekuvandudza mashandiro ekuvaka. Kuita kwakanaka kwekuchengetedza mvura kunovimbisa kuti dhaka harizokonzeri jecha, upfu uye kuderedzwa kwesimba nekuda kwekushomeka kwemvura uye isina kukwana simende hydration; iyo thickening mhedzisiro inowedzera zvakanyanya kusimba kwechimiro chedhaka rakanyorova, uye kuwedzerwa kwemethyl cellulose ether kunogona pachena Kuvandudza kunyorova kwemvura yedhaka rakanyorova, uye kuve nekunamatira kwakanaka kune akasiyana substrates, nekudaro kuvandudza kushanda kwedhaka rakanyorova pamadziro uye kuderedza. waste.

Kazhinji kutaura, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Nekudaro, iyo yakakwira viscosity, iyo yakakwira molecular huremu hweMC, uye kunyungudika kwayo kunenge kwakadzikira, izvo zvinogona kuve nemhedzisiro yakaipa pakusimba uye kuita kwekuvaka kwedhaka. Iyo yakakwirira viscosity, iyo inonyanya kuoneka iyo thickening maitiro padhaka, asi haina kuenzana zvakananga. Iyo yakakwirira iyo viscosity, iyo yakanyanya viscous iyo dhaka rakanyorova richava. Panguva yekuvaka, inoratidzirwa sekunamatira kune scraper uye yakakwirira kunamatira kune substrate. Asi hazvibatsiri kuwedzera simba rekuumbwa kwevhu rakanyorova pacharo.

Zvenyama nemakemikari zvivakwa:

1. Kuonekwa: chena kana kuti isina-white powder.
2. Particle size: 80-100 mesh pass rate yakakura kudarika 98.5%; 80 mesh pass rate i100%.
3. Carbonization tembiricha: 280-300°C
4. Inooneka density: 0.25-0.70 / cm3 (kazhinji inopoteredza 0.5 / cm3), chaiyo giravhiti 1.26-1.31.
5. Discoloration tembiricha: 190-200°C.
6. Kushungurudzika kwepamusoro: 2% mhinduro yemvura ndeye 42-56dyn / cm3.
7. Soluble mumvura uye zvimwe zvinonyungudutsa, zvakadai se ethanol / mvura, propanol / mvura, trichloroethane, nezvimwewo muzvikamu zvakakodzera. Aqueous solutions is surface active. Kujeka kwepamusoro uye kushanda kwakagadzikana. Madiro akasiyana ezvigadzirwa ane tembiricha dzakasiyana dzegel, uye solubility inoshanduka ne viscosity. Iyo yakaderera viscosity, iyo yakakura solubility. Madiro akasiyana eHPMC ane mimwe misiyano mukuita, uye kunyungudika kweHPMC mumvura hakukanganiswe nehukoshi hwepH.
8. Nekuderedzwa kwemethoxyl content, gel point inowedzera, mvura yakanyunguduka yeHPMC inoderera, uye basa repamusoro rinodererawo.
9. HPMC inewo maitiro ekukora kukwanisa, kusaramba kwemunyu, kuderera kwedota, kugadzikana kwePH, kuchengetedza mvura, kugadzikana kwedimensional, kuumbwa kwemafirimu akaisvonaka, uye zvakasiyana-siyana zvekudzivirira enzyme, dispersibility uye kubatana.

Chinangwa chikuru:

1. Indasitiri yekuvaka: Sechinhu chinochengetedza mvura uye chinodzoreredza chesamende dhaka, inogona kuita kuti dhaka ripombike. Inoshandiswa sebhainda mupurasita, purasita, putty poda kana zvimwe zvekuvaka kuvandudza kupararira uye kurebesa nguva yebasa. Inogona kushandiswa sekuisa mataira, marble, kushongedzwa kwepurasitiki, paste yekusimbisa, uye inogona zvakare kuderedza huwandu hwesimende. Kuita kwekuchengetedza mvura kweHPMC kunodzivirira slurry kubva pakutsemuka nekuda kwekuoma nekukurumidza mushure mekushandisa, uye inowedzera simba mushure mekuoma.
2. Ceramic kugadzira indasitiri: Inoshandiswa zvakanyanya sebhainda mukugadzira zvigadzirwa zveceramic.
3. Indasitiri yekuputira: Inoshandiswa seyakakura, inoparadzanisa uye yakagadzikana mumhizha yekuputira, uye ine kuwirirana kwakanaka mumvura kana organic solvents. Inogona kushandiswa mukubvisa pendi.
4. Ink kudhindwa: Inoshandiswa seyakakora, dispersant uye stabilizer muindasitiri yeinki, uye ine kuenderana kwakanaka mumvura kana organic solvents.
5. Plastiki: inoshandiswa sekugadzira kuburitsa agent, softener, lubricant, nezvimwe.
6. Polyvinyl chloride: Inoshandiswa seanoparadzira mukugadzirwa kwepolyvinyl chloride, uye ndiyo inonyanya kubatsira mumiririri wekugadzira PVC nekumisa polymerization.
7. Vamwe: Ichi chigadzirwa chinoshandiswawo zvakanyanya mumatehwe, zvigadzirwa zvemapepa, kuchengetedza michero nemiriwo uye maindasitiri emachira.

Nzira yekunyungudutsa uye kushandisa:

1. Tora 1/3 kana 2/3 yehuwandu hunodiwa hwemvura inopisa uye inopisa kusvika pamusoro pe85 ° C, wedzera cellulose kuti uwane slurry yemvura inopisa, wobva wawedzera imwe yakasara yemvura inotonhora, ramba uchikurudzira, uye utonhodze. mhedzisiro musanganiswa.
2. Gadzira chinwiwa chaamai chakaita seporridge: tanga wagadzira HPMC chinwiwa chaamai chine huwandu hwepamusoro (iyo nzira yakafanana neyepamusoro kune slurry), wedzera mvura inotonhora uye ramba uchikurunga kusvika pajekerere.
3. Dry yakasanganiswa kushandiswa: Nekuda kwekuenderana kwakanakisa kweHPMC, inogona kusanganiswa zviri nyore nesamende, gypsum poda, pigments uye mafirita, nezvimwewo, uye kuzadzisa zvinodiwa.

Package, kuchengetedza uye kudzivirira kwekufambisa:

Yakaputirwa mumapepa epurasitiki kana makadhibhokisi akaiswa mabhegi epurasitiki epolyethylene, uremu hwemambure pabhegi: 25kg. Yakavharirwa kuchengetedza. Dzivirira kubva kuzuva, kunaya uye unyoro panguva yekuchengeta nekufambisa.
