Yakadzika viscosity: 400 inonyanya kushandiswa kune yekuzvikudza, asi inowanzoiswa kunze kwenyika.
Chikonzero: Yakaderera viscosity, kudzikisira kwemvura kwemvura, asi yakanaka yekufambisa midziyo, yakakwira motsi.
Pakati nepakati uye zvakaderera viscosity: 20000-0000 inonyanya kushandiswa kune tiles inonamatira, inokanda mumiriri, anti-crack motsi, yekubatanidza kusimbisa kusanganisa motsi, nezvimwe.
Zvikonzero: Kubata kwakanaka, kushoma mvura yakawedzerwa, uye yakakwirira motsi desity.
1. Ndedzipi zviripo zvinoshandiswa nehydroxyprupyl methylcellose (HPMC)?
- HPMC inogona kukamurwa mu: Giredhi rekuvaka, giredhi rekudya uye pharmaceuce grade zvichienderana nekushandiswa. Parizvino, zvigadzirwa zvemuviri zvakanyanya pane giredhi rekuvaka. Muchigadzirwa chekuvaka, putty poda inoshandiswa mune yakakura mari, inenge 90% inoshandiswa kune putty poda, uye iyo yakasara inoshandiswa kune simende dhiri uye glue.
2. Mangani marudzi emhando dze hydroxyprupyl methylcellose (HPMC) variko? Ndezvipi zvinoshandiswa nezvavo?
- Zvigadzirwa zvekunze zvinopararira nekukurumidza mumvura inotonhora uye nekunyangarika mumvura. Iyo mvura haina zvisizvo panguva ino nekuti iyo HPMC inopararira mumvura uye isina kunyungudutswa. Mushure memaminitsi maviri, iyo viscosity yemvura inowedzera zvishoma nezvishoma uye iyo turuki yeViscous colloid inoumbwa. Kupisa-kuchena zvigadzirwa kunogona kukurumidza kupararira mumvura inopisa uye nekunyangarika mumvura inopisa kana ichisangana nemvura inotonhora. Kana tembiricha ikadonha kune imwe tembiricha (yechigadzirwa chedu chekambani ndeye 65 degrees celsius), iyo viscosity zvishoma nezvishoma inoonekwa kusvikira iyo yeVictapar Hiscous Colloid. Hot Melt mhando inogona kungoshandiswa chete kune putty poda uye dhaka. Mumvura glue uye pendi, clumping ichaitika uye haigone kushandiswa. Iyo inokurumidza mhando ine huwandu hwakakura hwekushandisa. Inogona kushandiswa kune poro poda, dhaka, mvura glue, uye pendi pasina kukanganisa.

- Vanopisa Mvura Dissolution Nzira: Sezvo Hpmc iri kuisirwa mumvura inopisa, HPMC inogona kuparadzirwa nemvura inopisa pane yekutanga nhanho uye nyungudika nekukurumidza mushure mekutonhora. Mikana miviri yakajairika inotsanangurwa pazasi:
1) Isa iyo inodiwa huwandu hwemvura inopisa mumudziyo uye uzvidzise kune anenge 70 ℃. Zvishoma nezvishoma wedzera hydroxyprupyl methylcellose neanononoka kumutsa. Pakutanga Hpmc inoyerera pane mvura yemvura, saka zvishoma nezvishoma inogadzira slurry, uye inotonhorera nekukurudzira.
2). Wedzera 1/3 kana 2/3 yehuwandu hunodiwa hwemvura mumudziyo, kupisa kusvika makumi manomwe Wobva wawedzera iyo yakasara huwandu hwemvura inotonhora kusvika kumvura inopisa slurry. Slurry mumvura, funga uye kutonhorera musanganiswa.
Powder inosanganisa nzira: Sanganisa HPMC Powder ine huwandu hukuru hweimwe zvinhu zveupfu, sanganisa zvakakwana ne blender, wobva wawedzera mvura kuti inyungudutsire. Panguva ino, iyo HPMC inogona kunyungudika uye haizokanganisa pamwe chete, nekuti kune zvishoma zveHPMC mune chikamu chimwe nechimwe. Kona diki. Iyo hupfu inodonha pakarepo pane kusangana nemvura. - Upty poda uye moterar Vagadziri vanotora nzira iyi. HydroxyPropyl methylcellose (HPMC) inoshandiswa seyakakwenenzverwa uye yemvura-yekuchengetedza mumiririri muPutty Poda dhiri.
4. Maitiro ekutonga mhando yehydroxypropyl methylcellose (HPMC) nyore uye intuitively?
- " Nekudaro, zvigadzirwa zvakanaka zvakawanda zvine machena machena. . Yakawanda yeHPMC yakagadzirwa mu hebei is 80 mesh. Akanaka anoyera zvakanaka. . Iyo yepamusoro iyo mwenje inodengenyeka, zviri nani, zvichiratidza kuti pane zvisinganyanye kusanzwisisika zvinhu mukati. Iyo Mhepo Kupararira Kwemutambi anowanzoita zviri nani pane izvo zvine hukasha tsika, asi hazvigone kutaurwa kuti mhando yevatambi vanokwanisa kupfuura izvo zviri nani pane izvo zvine hukasha. Pane zvinhu zvakawanda zvinozivisa chigadzirwa hunhu. . Iyo chaiyo gravity inowanzo nekuda kweiyo yakakwira hydroxyprupropropyl mukati maro. Iyo yepamusoro iyo hydroxyprupropyl yezvinyorwa, zvirinani kuchengetwa kwemvura.
5. Chii chinonzi dosage ye hydroxyprupyl methylcellose (HPMC) muPutty poda?
- Vanoshamisa: Iyo Dosage yeHPMC mune chaiyo application inosiyana zvinoenderana nemamiriro ekunze, tembiricha, yemunharaunda ash calcium mhando, uye yekuisa fomula. ty poda uye "vatengi-zvinodiwa mhando". Kazhinji, iri pakati pe4KG uye 5KG. Semuenzaniso, yakawanda putty poda muBeijing ndeye 5 kg; Vazhinji putty poda muGuizhou ndeye 5 kg muzhizha uye 4.5 kg munguva yechando;
6. Ndeipi iyo yakakodzera viscosity ye hydroxyprusyl methylcellose (HPMC)?
- Vanodzora Uye iyo yakakosha basa reHPMC kuchengetwa kwemvura, ichiteverwa nekukora. MuPocty poda, chero bedzi ichine mvura yakanaka yekuchengetwa uye yakadzika viscosity (70,8000), zvakanaka. Ehe, iyo yepamusoro viscosity, zvirinani kugarisana kwemvura. Kana visikoity inopfuura 100,000, iyo viscosity ine zvishoma mhedzisiro yekuchengetwa kwemvura.
7. Ndezvipi zviratidzo zvehunyanzvi zvehunyanzvi zve hydroxyprupyl methylcellose (HPMC)?
- Iyo yepamusoro iyo hydroxyprupropyl yezvinyorwa, zvirinani kuchengetwa kwemvura. Nezvevarwi vekakwirira, kuchengetwa kwemvura kuri kuita (kwete zvachose) zviri nani, uye nekwakakwirira viscosity, inoshandiswa zviri nani mumutumbi wetsiva.
8. Ndezvipi zvinhu zvikuru zvekushandisa zvehydroxyprupyl methylcellose (HPMC)?
- A: A: Iyo huru mbazyi yeHydroxyPropyl methylcellose (HPMC): Yakanatswa Cottoni, methyl Cotride, Zvimwe Zvinyorwa Zvinosanganisira Soda, Acid, Toluene, isopropyl doro, nezvimwe.
9. Ndeipi basa guru reHPMC mukushandisa kwePutty poda? Ine chero mhedzisiro yemakemikari here?
- Vanswer: HPMC ine matatu makuru mabasa ekuremerwa, kudzokorora kwemvura uye kuvakwa muPutty poda. Kukakavara: Cellulose kunogona kumiswa, chengetedza mhinduro yunifomu uye udzivise sagging. Kudzokorora kwemvura: Ita iyo Powder poda yakaoma zvishoma nezvishoma uye ubatsire kuita kwegrey calcium pasi pekuita kwemvura. Kuvaka: Cellulose ine mwero unogadzirisa uye kunogona kuita kuti ibwe rekutya riwedzere kushanda zvakanaka. HPMC haibatanidzi mune chero mhedzisiro yemakemikari uye chete inotora basa rebonde. Kana powty poda inowedzerwa kumvura uye yaishandiswa kumadziro, maitiro emakemikari achaitika. Sechinhu chitsva chakaumbwa, iyo poro poda pamadziro inobviswa kubva kumadziro uye pasi muupfu usati washandiswa. Izvi hazvishande nekuti chinhu chitsva (calcium carbonate) yaumbwa. ) kumusoro. Izvo Zvikuru zveGrey Caldium Pokwanges ndeye: Ah) yeCA (OH) 2, Cao + CAC (OH) 2 + CACO3 ↓ + H2O Grey Calcium Kudonha mumvura uye mhepo CO2 pasi pechiitiko checalcium carbonate, HPMC chete inochengetedza mvura uye inobatsira grey calcium yekuita zvirinani, uye haitore chikamu chero chipi zvacho chaicho.
10. HPMC ndeye isiri-ionic cellulose ether, saka chii chisiri-ionic imwe?
A: Muviri's Mitemo, isiri-ions zvinhu zvisinga ifunge mumvura. Ionization ndiyo maitiro ayo electrolytes yekuparadzaniswa mumugwagwa wakasununguka kupomerwa pachena Semuenzaniso, sodium chloride (NACL), munyu wakapedza zuva rega rega, unopaza mumvura uye kusekwa, kubereka zvakasununguka mbozha kwakanaka kuchengetedzwa sodium ions (na] Ndokunge, iyo hpmc ichiiswa mumvura, haina kusiyanisa kupururudzwa
