Chii chinonzi Mhec methyl hydroxytHyl cellulose?

Methyl hydroxytletl cellulose (mhec): kutevedzana kwakazara

Nhungamidzo:

Methyl Hydroxylyl CelluloseS, inowanzo kupfupikiswa seMhec, mheremalose ether iyo yakawana mukurumbira maindasitiri akasiyana siyana ezvivakwa zvakasiyana uye zvakasiyana siyana. Uyu makemikari anobva kune cellulose anowana maficha mukuvaka, mishonga yemishonga, cosmetics, nezvimwe. Mukuwongorora uku kwakazara, isu tinodzungudza muchimiro, zvivakwa, maitiro ekugadzira, uye maficha akasiyana eMheC.

Chemical dhizaini:

Mhec ishanduro yakashandurwa cellulose ether inotorwa kubva kune yakasikwa polymer cellulose, yakaomarara carbohydrate inosanganisira zvikamu zveglucose. Iko kugadziridzwa kunosanganisira kuunza methyl uye hydroxytem mapoka kune iyo cellulose backbone. Uku kunyatsochinja kunopa hunhu chaiwo kune mhec, zvichiita kuti zviite zvakaringana kune huwandu hwakawanda hwekushandisa.

Zvivakwa zveMheC:

1. Kukoshesa uye viscosity control:

MheC inozivikanwa nezvivakwa zvavo, zvichiita kuti ive mumiriri inoshanda yekudzora mavisikopo emhinduro dzemhinduro. Hunhu uhwu hunonyanya kukosha mumaindasitiri ipo precise rheological kudzora kukosha kwakakosha, senge mukuumbwa kwemapendi, madekirwo, uye zvigadzirwa zvakasiyana zvemvura.

2. Kuchengeta mvura:

Chimwe chezvinhu zvisingabatsiri zveMHEC ndiko kugona kwayo kuchengetedza mvura. Mudenga rezvivakwa zvekuvaka, vakadai sevhu uye simende, mhec inoshanda seyekuchengetwa kwakanaka kwemvura. Kugona uku kunobatsira kudzivirira nekukurumidza kuomesa, kusimudzira kugona uye kushanduka mukushandisa kwezvinhu izvi.

3. Binder mune zvigadzirwa zvekuvaka:

MheC inotora basa rakakosha seyakagadzirwa mukuumbwa kwezvigadzirwa zvekuvaka. Tile anomisheni, simende-yakavakirwa, uye maCommins ejoins inobatsira kubva pakuwedzera kweMHEC, iyo inovandudza maitiro avo ese uye kusimba.

4. Pfekceutical uye cosmetic zvikumbiro:

Maindasitiri emishonga uye ecometic akambundira mhec kuti awirirane. Muchirongwa chemishonga, Mhec anoshanda seanoshanda, stabilizer, uye binder mumhando dzakasiyana-siyana mishonga uye inosanganisira mishonga yemuromo uye yekunyora mishonga yakafanana neoxtments uye mafuta. Saizvozvo, iyo indasitiri yeCosmetic inosanganisira maHEC yeakakwanisa kusimudzira iwo mamiriro uye kugadzikana kwezvigadzirwa.

5. Firimu-kugadzira zvivakwa:

MheC inoratidza zvivakwa zvefirimu, zvichiita kuti zviite zvakaringana zvekushandisa mumatombo uye kuomerera. Hunhu uhwu hunobatsira kuumbwa kwemufirimu anodzivirirwa uye anodzivirira, achiwedzera kuita kwechigadzirwa chekupedzisira.

Kugadzira Maitiro:

Iko kugadzirwa kweMheC kunosanganisira matanho akati wandei, kutanga nekubvisa mheremalose kubva kune zvakadyara-zvakavakirwa zvinyorwa. Wood Prap inozivikanwa kutanga zvinhu, kunyangwe zvimwe zvinowanikwa kunge machira uye zvimwe zvidyarwa zvidyarwa zvinogona kushandiswawo. Iyo cellulose inoshandiswa yakaiswa pasi pekugadziridzwa kwemakemikari kuburikidza nekutsvagira maitiro, kuunza methyl uye hydroxytem mapoka kune cellulose ketani. Dhigirii rekutsiva uye suremu hwesimbi rinogona kudzorwa panguva yekugadzira, vachibvumira kugadziriswa kweMhec kuti vasangane nezvaanoda.

Zvikumbiro zveMheC:

1. Indasitiri yekuvaka:

MheC anowana zvakanyanya kushandiswa mune yekuvaka indasitiri. Semumiriri wemvura kuchengetwa, zvinokwidziridza kushanda kwezvekushandisa zvemisangano, zvinosanganisira madhiri uye kutambudzika. Zvivakwa zvaro zvinosunga zvinopa kune iyo yekuumbwa kweiyo yakakwirira-yekuita tile inonamira, plaster, uye maCosjounds.

2. PMEMACEFICAL FORFUTIONS:

Muchikamu chechikadzi, mhec anoshandirwa mune dzakasiyana siyana mafambiro. Basa rayo sekureva kwemubatanidzwa uye binder rakakosha mukugadzirwa kwemahwendefa, makapu, uye mafomu epamusoro. Kudzoserwa Kuburitswa Kuendesa Kukutumira Masisitimu kunogona kubatsirwawo kubva kuMhec's rheological zvivakwa.

3. Cosmetics uye zvigadzirwa zvega zvega:

Cosmetic mafomu anowanzobatanidza mhec kuti uwane chimiro chaunoda, kugadzikana, uye viscosity. Makiromita, mafuro, uye maGels anogona kushandisa mhec seanotenda uye stabilizer, inopa kune huwandu hwakazara uye huremu hwezvigadzirwa zvezvigadzirwa izvi.

4. Pists uye majasi:

Iyo pendi uye inovhara indasitiri yekuwedzera mhec yeyakaomerera uye mafirimu-ekugadzira zvinhu. Iyo inobatsira mukudzivirira kusekerera kana kudonhedza panguva yekushandisa uye inobatsira kuumbwa kweyunifomu uye kusimba kwekuchera.

5. Anoshivirira:

MheC inotora chikamu mukuumbwa kwezvinoshatirwa, zvichikonzera kune yavo visikopa uye kusimba simba. Yayo firimu-yekugadzira midziyo inosimudzira mashandiro ekubatanidza ekumanikidza kuomerera pane akasiyana substrates.

Zvemamiriro ekunze uye ekuzvidzora pfungwa:

Sezvinei nechero chinhu chipi nechipi chemakemikari, iyo nharaunda uye yekuzvidzora zvikamu zveMhec vanofungisisa vanofunga. Iyo biodegradability yeMHEC, pamwe chete nekugona kwayo pamisangano uye hutano hwevanhu, dzinofanira kunyatsoongororwa. Zvitumbarire miviri, yakadai seyakatsigira kuchengetedza

Methyl HydroxylLYL Cellulose, ine musanganiswa wayo wakasarudzika wezvivakwa, zvave chinhu chakakosha chinhu muzvishandiso zvakasiyana zvechiindasitiri. Kubva pakuvandudza mashandiro ezvivakwa zvekuvaka kuti ubatsire pakugadzira uye kugadzikana kwemishonga yemishonga uye cosmetics, mhec inoramba ichitamba chiitiko chakakosha. Maindasitiri anochinja uye kudiwa zvekusimudzira uye zvinoshanda zvinhu zvinokura, zvinowanikwazve zveMhec zvinzvimbo zvakaita semutambi wemamiriro ezvinhu emazuva ano. Kuenderera mberi kwekutsvaga uye kusimudzira kungangoda mukana mitsva nezvinonyorera, kuwedzera kusimbisa kukosha kweMheC mukugadzira ramangwana reramangwana rakawanda maindasitiri akawanda.
