Mhedzisiro ye cellulose ether (HPMC MheC) pane Dururu Kubatanidza Simba

Cellulose ether (senge hpmc, hydroxyprEpropyl methylcellose) uye methyl hydroxyll cellylosel cellylosel cellylosel Celluloseet. Ivo vanoita basa rakakosha mukuvandudza simba rekubatanidza remauto, vachivandudza kuita zvekuvaka uye kuendesa nguva yekuvhima yemaroyi.

1. Basic presties yeHPMC uye MHEC
HPMC ndeye polymer yakawanikwa yakawanikwa nemakemikari kugadziridzwa kwemasikirwo emusikirwo cellulose. Mamorekuru ayo ane hydroxypruppropyl uye methyl mapoka, ayo anoita kuti ive neakanaka mvura solubility, kureruka uye kugadzikana. MheC yakafanana neHPMC, asi ine zvimwe hydroxytHyl mapoka mune yayo moleky chimiro, saka iyo solubility yemvura uye kuita kwekuita kweMhec kwakasiyana. Ivo vaviri vanogona kuumba network dhizaini mune dhiragi uye kusimudzira zvivakwa zvemuviri zvevhu.

2.
Mushure mekuwedzera HPMC kana mhec kune dorari, iyo cellulose ether mamorekuru inoumba iyo yakagadzikana kodhi kuburikidza neyekudyidzana nemvura, zvimwe zvemakemikari zvikamu uye mineral zvimedu zvemaminerari. Iyi sisitimu inogona kuvandudza zvakanyanya maitiro ekubatanidza emota.

Kuita kwakasimba: HPMC uye mhec inogona kuwedzera kuwirirana kwerufu, zvichiita kuti zvive nyore kushanda panguva yekuvaka. Izvi zvinokanganisa zvinobatsirawo kuderedza iyo clifity yeSette pasita, kuvandudza kuderedza kweura, uye nekudaro kusimudzira simba rekubatanidza remota.

Kuchengeta mvura

Kuvandudza Fluidity uye Kuvaka Kubata: Cellulose Ether inobatsira kuvandudza iyo fluidity yemutaundi, ichibvumira kuti iite zvakanyanyisa pamusoro pechikamu, icho chinokodzera kugoverwa kuyasha.

3. Mhedzisiro ye cellulose ether paMortar Boging Simba
Kuwedzerwa kwe cellulose kusvetukira kune motsi kazhinji kunobata zvakananga kusimbisa simba remutya. Zvakananga, mhedzisiro yeHPMC uye MheC pane dhiri rekubatanidza Simba Rakaratidzwa Mune Zvinotevera Zvinhu:

3.1 pesvedzero pane yekutanga kushamwaridzana simba remutya
HPMC uye MHEC inogona kuvandudza mashandiro ekubatanidza pakati pemutumbi uye pasi. Kana iko kuvakwa kwapera, simba rekubatanidza pakati peguruva uye substrate zvakanyatsogadziriswa nekuti cellulose ether inogona kuchengetedza mvura uye kuderedza kuomesa kwepamberi kweiyo coment. Izvi zvinodaro nekuti simende hydration maitiro inogona kuenderera zvakanaka, iyo inosimudzira kuomarara kweiyo duri.

3.2 pesvedzero pane refu-terming kushamisika simba remutya
Nekufamba kwenguva, chikamu chekeni chinofamba-famba chiri kuenderera mberi hydration maitiro, uye simba rerudzi richaenderera mberi nekuwedzera. Kuchengetwa kwemvura kwemvura kwe cellulose kuchaita basa rakakura kuita izvi, kudzivisa kusarudzika kwemvura mumvura mudhaka, nekudaro kuderedza kuderedzwa kwesimba kunokonzerwa nemvura isina kukwana.

3.3 Kuvandudza kupaza kupokana kwekuita moter
HPMC uye MheC inogona zvakare kugadzirisa iyo crack kudzikisira kwemota. Maitiro ayo echiito anonyanya kusimudzira kugadzikana kwemukati kwechikadzi uye kudzora mwero wemvura pamusoro pemvura pamusoro pehudyu, nekudaro kuderedza dambudziko rekupenga rinokonzerwa nekubuda kwemvura. Uye zvakare, iyo collodal chimiro chakaumbwa ne cellulose ether mune motsi inogona kuvandudza kuomarara kweiyo duri, zvichiita kuti zvisingakwanisi kupaza kana kuiswa mumasimba ekunze.

3.4 Mhedzisiro pane iyo simba kuvandudzwa kwemutumbi
Zvidzidzo zvakaratidza kuti kuwedzera huwandu hwakakodzera hweHPMC kana mhec zvinogona kuvandudza kusanganisa simba remutema pasina kuwedzera zvakanyanya uremu hwemutya. Kazhinji, iyo yakakwana dosage ye cellulose ether ndeye 0.5% -1.5%. Kuwedzeredza kunyanyisa kunogona kukonzera kuti dhaka iite yakanyanya kunaka, iyo inoshanduka inokanganisa zvivakwa zvayo. Naizvozvo, huwandu hwakaringana hwemheremalo e cellulose ether rakawedzerwa rakakosha kuvandudza kusanganisa simba remutya.

4. Kuenzanisa kwemhando dzakasiyana dze cellulose ana
Kunyangwe HPMC uye MheC zvakafanana mumuchina wavo wechiito, mhedzisiro yavo pane kusimbisa simba remutya rakasiyana mukushandisa chaiko. MheC iri hydrophilic kupfuura hpmc, saka munharaunda yakanyorova, MheC inogona kuve nemhedzisiro yakakosha pakuvandudza simba rekubatanidza. HPMC, kune rumwe rutivi, yakagadzikana pasi pekudziya kwakajairwa uye kwakanyorova mamiriro, uye kwakakodzera zvakanyanya kune imwe gadziriro yechinyakare.

Cellulose ana eter (HPMC uye MHEMC) zvinowanzo shandiswa zvinowedzera zvevhudzi, izvo zvinonyanya kuvandudza simba rekubatanidza kwemauto kuburikidza nekuchengetwa kwemvura, uye nekuchengetwa kwemvura, uye nekuvandudzwa kwemvura. Kushandisa zvine musoro kwe cellulose ether hakugone kungosimudzira kusimudzira pakati pevhu uye zvakare Mhando dzakasiyana dze cellulose ether ane akasiyana mashandiro, uye kusarudza chigadzirwa chakakodzera uye dosage yakakosha kuvandudza kuita kwemota.
