Yakadzika viscosity HPMC: HPMC 400 inonyanya kushandiswa kune inokwenenzverwa pachako, asi kazhinji inotorwa kunze.
Chikonzero: Iyo yekuona yakaderera, kunyangwe kuchengetwa kwemvura kuri murombo, asi kukwirira kwakanaka, uye mongororo yakakwirira yakakwira.
Pakati uye yakaderera viscosity:hydroxypruppropyl methylcelloseHPMC 20000-
Chikonzero: Kubata kwakanaka, kushoma mvura yekuwedzera, yakanyanya kuumbwa.
1. Ndeipi chinangwa chikuru che hydroxypropyl methylcellose (HPMC)?
- HPMC inogona kukamurwa mu: Giredhi rekuvaka, giredhi rekudya uye giredhi rechiratidzo maererano nechinangwa. Parizvino, yakawanda yezvinhu zvigadzirwa zvemberi ndeyekuvaka giredhi. Mugiredhi rekuvaka, huwandu hweiyo putty poda yakakura kwazvo, inenge 90% inoshandiswa kune putty poda, uye kuzorora kunoshandiswa kune simende dhiri uye glue.
2. Kune akati wandei marudzi e hydroxypropyl methylcellose (HPMC), uye chii musiyano mukushandisa kwavo?
-Vaneswer: HPMC inogona kukonzereswa mune instant mhando uye inopisa-nyauka mhando. Instant-mhando zvigadzirwa zvinopararira nekukurumidza mumvura inotonhora uye ichipinda mumvura. Panguva ino, iyo mvura haina viscosity, nekuti HPMC inongoparadzirwa mumvura uye haina kunyungudika chaiko. Mushure memaminitsi maviri, iyo viscosity yemvura zvishoma nezvishoma yakawedzera, inogadzira iyo yakajeka viscous colloid. Kuzvidza-kupera zvigadzirwa, kana kusangana nemvura inotonhora, kunogona kukurumidza kuparadzirwa mumvura inopisa, uye nekunyangarika mumvura inopisa. Kana tembiricha ikadonha kune imwe tembiricha (yechigadzirwa chekambani yedu ndeye 65 degrees celsius), iyo viscosity zvishoma nezvishoma inoonekwa kusvikira yamuratidza viscous viscous. Iyo inopisa-nyauka mhando inogona kungoshandiswa chete mune putty poda uye dhaka. Mumvura glue uye pendi, inobvisa phenomenon ichaitika uye haigone kushandiswa. Iyo Instant Type ine huwandu hwakakura hwekushandisa. Inogona kushandiswa muPutty poda uye dhaka, pamwe chete mumvura glue uye pendi, pasina kupokana.
3. Ndedzipi nzira dzekupaza dze hydroxyprupyl methylcellose (HPMC)?
- Vanopisa Mvura Dissolution Nzira: Sezvo HPMC haina kunyungudutswa mumvura inopisa, HPMC inogona kuparadzaniswa mumvura inopisa pane imwe nhanho, uye ndokukurumidza kunyungudutswa kana ichinge yanyungudika kana ichinge yadzikira. Nzira mbiri dzakajairika dzinotsanangurwa seinotevera:
1) Isa iyo inodiwa huwandu hwemvura inopisa mumudziyo uye uzvidzise kune anenge makumi manomwe c. Iyo hydroxyprupyl methylcellose yakawedzerwa zvishoma nezvishoma nekukurudzira zvishoma nezvishoma, pakutanga iyo HPMC yakadzika pamusoro pemvura, uye zvishoma nezvishoma yakaumbwa slurry, iyo yakatonhorera nekukurudzira.
2), wedzera 1/3 kana 2/3 yehuwandu hunodiwa hwemvura mumudziyo, uye uzvidzise kusvika 70 ° C, maererano nenzira ye1), Durperse HpMC, gadzirira mvura inopisa slurry; Wobva wawedzera iyo yakasara huwandu hwemvura inotonhora kumvura inopisa mune iyo slurry, musanganiswa wacho wakatonhorera mushure mekukurudzira.
Powder kusanganisa nzira: Sanganisa HPMC Powder ine huwandu hwakawanda hweimwe zvinhu zvePowder, uye wozowedzera mvura yekunyungudika panguva ino pasina kuunganidzwa pamwe chete, nekuti kune zvishoma hpmc mune yega yega kona diki diki. Iyo hupfu ichanyungudika pakarepo mukubatana nemvura. - Iyi nzira inoshandiswa nePutty poda uye vagadziri vemota. [Hydroxyprenyl methylcellose (HPMC) inoshandiswa seanoshandiswa seanoti uye mvura-yekuchengetedza mumiririri mune putty poda. ]
4. Maitiro ekutonga mhando yehydroxypropyl methylcellose (HPMC) nyore uye intuitively?
- " Nekudaro, zvakawanda zvezvigadzirwa zvakanaka zvine machena machena. . Yakawanda yeHPMC yakagadzirwa mu hebei is 80 mesh. Iye anokakavara, zviri nani. . Iyo yepamusoro iyo inotapurirana, zviri nani, zvichiratidza kuti pane zvisinganyanye kusanzwisisika zvinhu mariri. Iko kubvumidzwa kweiyo Vertical Recort Kazhinji, uye iyo inotsanangurwa inowedzera, asi haigone kutaurwa kuti mhando yemutambi wechiitiko iri nani pane iyo yekutsauka, uye pane zvinhu zvakawanda zvinoona maitiro echigadzirwa. . Simba renyama rakakura, kazhinji nekuti hydroxyprupropiropropyari mukati mayo yakakwira, uye iyo hydroxyprupropropyl yezviri kumusoro, kuchengetwa kwemvura kuri nani.
5. Iyo huwandu hwe hydroxypropyl methylcellose (HPMC) muPutty poda?
- Vanowedzera: Iyo huwandu hweHPMC inoshandiswa mukushandisa zvinoshanda zvichienderana nemamiriro ekunze, tembiricha yemhando yemhando, iyo formula yePutty poda uye "mhando inodikanwa nevatengi". Kazhinji, iri pakati pe4 kg uye 5 kg. Semuenzaniso, mazhinji eiyo putty poda muBeijing ndeye 5 kg; Vazhinji vePutty poda muGuizhou ndeye 5 kg muzhizha uye 4.5 kg munguva yechando;
6. Ndeipi iyo yakakodzera viscosity ye hydroxyprusyl methylcellose (HPMC)?
- Vanotya: Pocty poda kazhinji inowanzoita 100,000 Yuan, uye duri rinonyanya kudiwa, uye zviri nyore kushandisa pana 150,000 Yuan. Uyezve, iyo yakakosha basa reHPMC ndeyekuchengeta mvura, ichiteverwa nekukora. MuPutty poda, chero bedzi kuchengetwa kwemvura kwakanaka uye visikoka kwakaderera (70,000-80,80000), zvinogonekawo. Ehe, visikoka yakakwira, uye kuchengetedza kwemvura kuri nani. Kana viscosity painopfuura 100,000, mhedzisiro ye viscosity pakuchengetwa kwemvura haina zvakawanda.
7. Ndezvipi zviratidzo zvehunyanzvi zvehunyanzvi zve hydroxyprupyl methylcellose (HPMC)?
- Vanogadzira: Hydroxyprusyl Zvemukati uye viscosity, vazhinji vashandisi vane hanya nezviratidzo izvi zviviri. Iyo yepamusoro iyo hydroxyprupropyl yezvinyorwa, zvirinani kuchengetwa kwemvura. Yakakwira viscossity, kuchengetwa kwemvura, pane zvakakwana (pane mhedziso) zviri nani, uye yakakwira viscosity, kushandiswa zviri nani mumutumbi wetsiva.
8. Ndezvipi zvinhu zvikuru zvekushandisa zvehydroxyprupyl methylcellose (HPMC)?
- A: A: Iyo mainini midziyo yehydroxypropyl methylcellose (HPMC): Yakanatswa Cotton, Zvimwe Zvinoshandiswa Oxide, Zvimwe Zvishandiso zvinosanganisira Flake Alkali, Acid, Toluene, isopropanol, etc.
9. Ndeipi basa guru reHPMC mukushandiswa kwePutty poda, uye pane chero kemistry?
- Vanswer: HPMC ine zvikamu zvitatu zvekukora, kudzokorora kwemvura uye kuvakwa muPutty poda. Kukakavara: Cellulose kunogona kuitwa kuti umise, chengetedza iyo yekugadzirisa yunifomu uye isingachinjiki, uye kuramba sagging. Kuchengeta kwemvura: Ita iyo POWDY POWDY yakaoma zvishoma nezvishoma, uye ubatsire zvakaitwa neAsh calcium pasi pechiitiko chemvura. Kuvaka: Cellulose ine mwero unogadzirisa, izvo zvinogona kuita kuti ibwe rekutya riwedzere kushanda zvakanaka. HPMC haitore chikamu mune chero maitiro emakemikari uye anongoita basa rebonde. Kuwedzera mvura kune iyo putty poda uye kuiisa pamadziro maitiro emakemikari. Nekuda kwekuumbwa kwezvinhu zvitsva, tora iyo poro poda pamadziro kubva pamadziro, ichikuya muupfu, uye uishandise zvakare. Izvo hazvizoshande, nekuti zvinhu zvitsva (calcium carbonate) zvakaumbwa. ) kumusoro. Zvikamu zvakakosha zveAshccium poda: Ah musanganiswa weCA (OH) 2, CAO + H2CA (OH) 2 + CACO3 ↓ + H2O ASH CALCIUM Mumvura uye mhepo iri pasi pechiitiko cheCo2, calcium kabhoni inogadzirwa, nepo Hpmc ichingokonzedza mvura uye inobatsira maitiro ari nani ealcium, uye haatore basa chero ripi zvaro.
10. HPMC isiri-ionic cellulose ether, saka isiri-ionic?
- Mhinduro: MuMitemo yaLayman, isingazivikanwe zvinhu zvisinga ifunge mumvura. Ionization inoreva maitiro ayo emagetsi anoparadzaniswa mune yakasununguka-inofamba yakaiswa pachena ion mune chaiyo solvent (senge mvura, doro). Semuenzaniso, sodium chloride (NACL), munyu wodyiwa mazuva ese, zvinopaza mumvura uye kusunganidzwa kuti ubudise zvakasununguka sodium Ndokunge, hpmc ichiiswa mumvura, hazvibvisire kupururirwa mhosva, asi zviripo muchimiro chemamorekuru.
