About hydroxypropyl methyl cellelose

1. Ndeipi huru kushandiswa kwemherombol?

HPMC inozoshandiswa zvakanyanya mune zvekuvaka, majasi, ceramics, mushonga, zvekudya, zvinyorwa, zvekurima, zvidhori, fodya uye mamwe maindasitiri. HPMC inogona kukamurwa kuita giredhi reindasitiri, giredhi rekudya uye pharmaceucal grade zvichienderana nekushandisa.

2. Kune akati wandei marudzi emasero, uye ndedzipi misiyano iri mukushandisa kwavo?

HPMC inogona kukamurwa kuita Instant Type (Brand Zita Suffix "s") uye inopisa-nyauka mhando. Instant-mhando zvigadzirwa zvinopararira nekukurumidza mumvura inotonhora uye ichipinda mumvura. Panguva ino, mvura haina viscosity nekuti HPMC inongoparadzirwa mumvura pasina kupaza chaiko. About (inomutsa) kwemaminetsi maviri, iyo viscosity yemvura inowedzera zvishoma, kugadzira iyo yechokwadi viscous viscous colloid. Kupisa-nyauka zvigadzirwa, kana uchisangana nemvura inotonhora, inogona kuparadzira nekukurumidza mumvura inopisa uye ichanyangarika mumvura inopisa. Kana tembiricha ikadonha kune imwe tembiricha (maererano neyechi tembiricha yechigadzirwa), viscosity ichaoneka zvishoma nezvishoma kusvika yamunoratidza viscous viscous.

3. Ndedzipi nzira dzekunyungudika cellulose?

1). Mhando dzese dzinogona kuwedzerwa kune izvo zvinyorwa nekuomesa kusanganisa;

2). Pazvinenge zvichida kuwedzerwa zvakananga kune yakajairika tembiricha mhinduro mhinduro, zviri nani kushandisa inotonhora mvura kuparadzanisa mhando. Izvo zvinowanzotora 1-30 maminitsi kusvika pakubata mushure mekuwedzera (stir uye stir)

3). Mhando dzakajairika dzinotanga kumutswa uye dzakapararira nemvura inopisa, yakabva yanyungudika mumvura inotonhora mushure mekunudza uye inotonhorera;

4). Kana Agglomeration inoitika panguva yekupararira, imhaka yekuti kusimudzira hakuna kukwana kana iyo yakajairika muenzaniso inowedzerwa zvakananga kumvura inotonhora. Panguva ino, inofanira kukurudzirwa nekukurumidza. the the

5). Kana mabhuru anogadzirwa panguva yekupararira, ivo vanogona kusiiwa kuti vamirire kwemaawa 2-12 (iyo nguva yakatarwa inotsanangurwa nekuenderana kwemhinduro) kana kudzvanywa, etc., uye huwandu hwakakodzera hwekudzvinyirira hunogona zvakare kuwedzerwa. the the

4. Maitiro ekutonga mhando ye cellulose chete uye intuitively?

1

2) chidimbu: Iyo yakajeka yeHPMC inowanzove ine 80 mesh uye 100 mesh, 120 mesh ishoma, iyo yakanaka kwazvo iyo yakanaka kwazvo.

3) Kuputika kwechiedza: Pashure peHPMC inoiswa mumvura kuti iite iyo yakajeka colod coloid, tarisa kujekesa kwayo. Kukura kwechiedza chinoputika, zviri nani, zvichiratidza kuti pane vasinganyanye kuisha mazviri, uye kutururwa kweVertical vanokwanisa kazhinji. , Iyo yakatsanangurwa yakatarisana, asi hazvireve kuti mhando yeiyo Vertical Recentor iri nani pane iyo yeiyo yakatarisana neTestor, uye pane zvakawanda zvinhu kuti uone hunhu hwechigadzirwa.

4) Scravitity chaiyo: Iyo yakakura iyo chaiyo gravity, inorema zviri nani. Iyo yakakwira iyo chaiyo gravity, yakakwira iyo hydroxyprupropyl zvemukati mune chigadzirwa. Iyo yepamusoro iyo hydroxyprupropyl yezvinyorwa, zvirinani kuchengetwa kwemvura.

5. Ndeipi huwandu hwe cellulose mune iyo putty poda?

Iyo huwandu hweHPMC inoshandiswa mune zvinoshanda zvinoshandiswa zvinokanganiswa nemamiriro ekunze, tembiricha, mhando yeyomunharaunda yeal calcium, iyo formula yePutty poda uye mhando inodikanwa nevatengi. Pane misiyano munzvimbo dzakasiyana, kazhinji ichitaura, iri pakati pe4-5 kg.

6. Ndeipi iyo yakakodzera viscosity yemasero?

Kazhinji, 100,000 PERTY POWOD yakaringana, uye chinodikanwa murofu chakakwira, uye zvinoda 150,000 kuva nyore kushandisa. Uyezve, iyo yakakosha basa reHPMC kuchengetwa kwemvura, ichiteverwa nekukora. MuPutty poda, chero bedzi kuchengetwa kwemvura kwakanaka uye visikoka kwakaderera (7-8), zvinogonekawo. Ehe, iyo yepamusoro viscosity, zvirinani kugarisana kwemvura. Kana viscosity painopfuura 100,000, iyo visikoka haina mhedzisiro yekuchengeta mvura. hombe.

7. Ndezvipi zviratidzo zvehunyanzvi zvehunyanzvi zve cellulose?

Hydroxyprupropyl zvemukati

Methyl Zvemukati

viscosity

Ash

Kurasikirwa pakuoma

8. Ndezvipi zvinhu zvikuru zvekushandisa zve cellulose?

Iyo mainini main midziyo yeHPMC: yakanatswa Cotton, methyl chloride, profyle oxide, mvura caustic soda, nezvimwe.

9. Ndeipi basa guru rekushandisa kwemheremalose muPutty poda? Pane chero kemikari maitiro?

Pakati peiyo poro poda hupfu, inotamba nhare nhatu dzekuremedza, kudzokorora kwemvura uye kuvaka. Kukakavara, cellulose kunogona kurira kumisa, chengetedza mhinduro yunifomu kumusoro uye pasi, uye udzivise kuswedera. Kudzokorora kwemvura: Ita iyo POWDY POWOD DOWDY IYO zvishoma zvishoma, uye ubatsire iyo ash calcium yekuita pasi pezviito zvemvura. Kuvaka: Cellulose ine lubricating mhedzisiro, iyo inogona kuita iyo poro poda ive nekuvakwa kwakanaka. HPMC haibatanidzi mune chero mhedzisiro yemakemikari, asi inotora chete basa rebonde.

10. Cellulose is non-ionic cellulose ether, saka isiri-ionic?

MuMitemo yaLayman, inert zvinhu hazvipindirani mumakemikari maitiro.

CMC (CarboxyMethyl Cellelose) ndeye cationic cellulose, saka ichashanduka kuva bani curd kana ichizosangana neAsh calcium.

11 Tembiricha yeGel yeCellulose ine chekuita here?

Iyo tembiricha yeHPMC ine chekuita neiyo nzira yayo yezvinyorwa, iyo yakadzika iyo nzira yezvinyorwa, yakakwira tembiricha.

12. Pane chero hukama pakati pehupamhi hwekurasikirwa kwePowder yePutty poda uye cellulose?

Kune hukama! ! ! Ndokunge, iyo murombo mvura yekuchengetwa kweHPMC inokonzeresa kurasikirwa kweupfumi (zvirimo zvezvinhu zvakaita seAsh, zvinorema calcium, uye tembiricha yekuvakira, uye mamiriro ekunze ese achikanganiswa).

13. Ndeupi musiyano uripo pakati pemvura inotonhora nekukurumidza uye inopisa soluble cellulose mukugadzira maitiro?

Mvura inotonhora mvura inokanda Izvo zvinongopera kana visikoity ichiwedzera. Hot Melt mhando hadzike pamusoro wakabatwa neGlyoxal. Kana huwandu hweGlyoxal hwakakura, kupararira kuchave kusimuka, asi visikoka kuchawedzera zvishoma nezvishoma, uye kana huwandu hushoma, zvakapesana zvichaitika.

14. Nei cellulose ane shuwa?

Iyo HPMC yakagadzirwa neiyo solvent nzira inoshandisa toluene uye isopropanol se solvent. Kana iko kugeza hakuna kunaka, pachave nechimwe chinhuhwidzo. (Kupora kwerarorization ndiyo yakakosha maitiro ekunhuhwirira)

15. Mashandisiro aunoita masisitimu akakodzera cellulose kwezvinangwa zvakasiyana?

Putty poda: inoda kuchengetedza kwemvura yakakwira, kusununguka kwakanaka

Yakajairika SEMENT-BASA REMAHARA: Inoda kuchengetedza kwemvura yakakwira, kupisa kwakanyanya kudziya, uye pakarepo viscosity

Kushandiswa kwekuvaka Glue: Zvigadzirwa zvakangoitika nekwakakwirira viscosity. (Yakakurudzirwa Giredhi

Gypsum Motar: Kukwirisa Kwemvura Yakakwira, Pakati uye Yakadzika Viscosity, Instant viscosity kuwedzera

16. Rimwe zita remumwe zita re cellulose?

Yakatumirwa seHPMC kana MHPC Alias ​​HyproMelose, Cellulose HydroxyPropropyl Ether.

17. Iko kushandiswa kwe cellulose muPutty poda, chii chikonzero cheBubbles mune iyo Putty poda?

MuPoWy poda, Hpmc inotora matanho matatu ekuremedza, kuchengetwa kwemvura uye kuvaka. Zvikonzero zveBubbles nderwe:

1. Mvura yakawanda yakawedzerwa.

2. Iyo yepazasi denderedzwa haina kuoma, ingo scrape imwe denderedzwa pamusoro, uye zviri nyore ku foam.

18. Ndeupi musiyano uripo pakati peCellulose uye MC:

MC Kazhinji, iyo degree rekutsiva ndeye 1.6-2.0, uye iyo solubility inosiyana nemadhigirii akasiyana ekutsiva. Zvakasiyana, ndezvevasina-ionic cellulose ether.

. Kazhinji, kana huwandu hwehuwandu hwakakura, hushoma hushoma, uye visikoka yakakura, iyo mwero wekuchengetwa kwemvura wakakwira. Pakati pavo, huwandu hwekuwedzera hune simba rakakura pane huwandu hwemvura hwevanhu. Iyo viscosity haina kuenzana kune iyo yekuchengetedza mvura. Iyo yekunyoroveswa chiyero inonyanya kuenderana nechiso che cellulose zvimedu. Degree rekushandurwa uye tangi rakaderera. Pakati pezvikamu zvakati zvakati wandei maCellulose ana ana ana methyl cellulose uye Jinshuiqiao cellulose yakakwira.

(2. Mhinduro kwayo yemvura yakagadzikana kwazvo mune huwandu hwePH = 3-12. Iyo ine kuwirirana kwakanaka nesrarch, nezvimwe uye akawanda surfactian. Kana tembiricha kana iyo denderedzwa tembiricha isati yasvika, glation ichaitika.

. Kazhinji, kukwidziridzwa kwekudziya, zvakanyanyisa kutarisirwa kwemvura. Kana tembiricha inodarika inopfuura makumi mana, kuchengetwa kwemvura methyl cellelose kuchave kuderedzwa zvakanyanya, uko kuchakanganisa zvakanyanya kuvakwa kwemutya.

. Kunamatira pano kunoreva kushushikana kwakanzwika pakati peiyo mushandi weMushandi weMushandi uye substate, ndiko kuti, iyo Shear Ristance yerudzi. Kunamatira kwakakwira, kurwisa Shefu kwakakura kwakakura, uye simba rinodiwa nevashandi vari mukati mekushandiswa kwakakura zvakare, uye kuita kwekuvaka kune murombo.
