MetHylcellose (MC) uye CarboxyMethylsellose (CMC) miviri yakajairika cellulose Defivives, anoshandiswa zvakanyanya mukudya, mushonga, kuvakwa, maindasitiri emakemikari uye mamwe minda. Kunyangwe ivo vese vakachinjika miviri yakagadziridzwa kubva kuNharaunda Cell Cellulose, kune misiyano yakakosha mumakemikari chimiro, zvemuviri uye zvemakemikari zvivakwa, uye zvinoshandiswa.
1. Chemical chimiro uye maitiro ekugadzirira
Methylcellose inogadzirwa nekuita cellulose ine methyl chloride (kana methanol) pasi pealkaline mamiriro. Munguva iyi, chikamu cheiyo hydroxyl mapoka (-OOH) muCellulose mamorekuru inotsiviwa nemhando dzemapoka (-Och₃) kuumba methylose. Dhigirii rekutsiva
CarboxyMethylcellose inogadzirwa nekuita cellulose neChloroalose Cellirocetic acid pasi peAlkaline mamiriro, uye iyo hydroxyl boka rinotsiviwa neCarboxymeymel (-ch₂coh). Dhigirii rekutsiva uye degree rePolymerization (dp) yeCMC inokanganisa iyo is solubility newiscoss mumvura. CMC inowanzovepo muchimiro cheSodium munyu, anonzi sodium carboxymellose (Nacmc).
2. Zvepanyama uye zvemakemikari zvivakwa
Solubility: Methylcellose inodonha mumvura inotonhora, asi inorasikirwa solubility uye inoumba gwenzi mumvura inopisa. Uku kudzoreredzwa kunoita kuti ishandiswe kwayo seanoridza mhere uye gelling mumiririri mukugadzirisa chikafu. CMC inonyura mumvura inotonhora uye inotonhora uye inopisa, asi visikopa yekugadzirisa kwayo kunoderera sezvo tembiricha inowedzera.
Viscosity: Iyo viscosity yezvese zvinokanganiswa neiyo degree rekutsiva uye mhinduro yekusimbisa. Iyo viscosity ye mc yekutanga inowedzera uye inoderera sezvo tembiricha inowedzera, nepo viscosity yeCMC inoderera sezvo tembiricha inowedzera. Izvi zvinovapa zvavo zvakanakira mune akasiyana maindasitiri ekushandisa.
PH Sungisisa MC iri kugadzikana pasi pemamiriro ezvinhu asina kwaakarerekera uye zvishoma nezvishoma, asi zvinosvibisa mune yakasimba acids kana alkalis.
3. Nzvimbo dzekushandisa
Indasitiri yechikafu: Methylcellose inowanzoshandiswa mune chikafu sediki, emulsifier uye stabilizer. Semuenzaniso, inogona kutevedzera kuravira uye kuumbwa kwemafuta kana uchigadzira chikafu chakaderera-mafuta. CarboxyMethylsellose anoshandiswa zvakanyanya mune zvinwiwa, zvinhu zvakabikwa uye zvigadzirwa zvemukaka senge thickener uye stabilizer yekuparadzanisa kwemvura uye nekuvandudza kuravira.
Indasitiri yechechi yechechi: Methylcellose inoshandiswa mukugadzirira kwemahwendefa emishonga semuchina uye nekuparadza uye nekudzivirira, senge muZiso reOphthalem inodonha seyekutsiva. CMC inozoshandiswa zvakanyanya mumushonga nekuda kwezvinhu zvakanaka zvakanaka, senge kugadzirira kwemishonga yakasimudzirwa uye inonamira mumadonhwe eziso.
Kuvaka uye indasitiri yemakemikari: Inogona kuvandudza maitiro ekuvaka uye mamiriro ekunze emidziyo. CMC inowanzoshandiswa mumatope emadhaka mumugodhi wemugodhi wemunda, slurry mune yekudhinda yekudhinda uye dhayi, pamusoro pekuvhara pepa, nezvimwe.
4. Kuchengetedza uye Zvakatipoteredza Dziviriro
Ose ari maviri anoonekwa akachengeteka kuti ashandiswe mune zvekudya uye mishonga yemishonga, asi masosi avo uye maitiro ekugadzira anogona kunge aine maitiro akasiyana pane zvakatipoteredza. Izvo zvigadzirwa zveMC uye CMC zvinotorwa kubva kune zvakasikwa cellulose uye zviri biodegradable, saka vanoita zvakanaka maererano neushamwari hwezvakatipoteredza. Nekudaro, maitiro avo ekugadzira anogona kusanganisira makemikari mashari uye reagents, ayo anogona kunge aine zvimwe zvinokanganisa nharaunda.
5. Mutengo uye Market Const
Nekuda kwekugadzira kwakasiyana maitiro, mutengo wekugadzira we methylcellose kazhinji kazhinji wakakwira, saka mutengo waro wemusika wacho zvakare wakakwira kupfuura carboxymethelose. CMC kazhinji ine yakakura yemusika inoda nekuda kwekunyorera kwayo kwekushandisa uye kuderera mari yekugadzira.
Kunyangwe methylcellose uye carboxymethylsellose ari ese anobva m cellulose, vane misiyano yakakosha muchimiro, zvivakwa, zvinoshandiswa uye zvinodikanwa zvemusika. MetHylcellose inonyanya kushandiswa muminda yechikafu, mushonga uye zvekuvaka uye zvekuvaka zvakakonzerwa nekudzoreredzwa kwayo kwekudzoreredza uye kukwidziridzwa kwepamusoro. CarboxyMethyl Cellalose inoshandiswa zvakanyanya mune chikafu, mushonga, petrochemical, machira uye mamwe maindasitiri nekuda kwekunyora kwayo solubility, gadziriso yekugadzirisa pH. Sarudzo ye cellulose inobviswa inoenderana neiyo chaiyo yekushandisa mamiriro uye zvinodiwa.
