CarboxyMethyl Cellelose (CMC) ndeyekunyanyisa kushandisa-sollxy yemvura-soluble polymer yakawedzera nekupararira kwakanaka, kureruka uye kugadzikana uye collodal. Inowanikwa nekutsiva mapoka ehydroxyl pane cellulose molecular cheni ine carboxymethyl mapoka (-ch2coh). This chemical modification makes the CMC molecule have strong hydrophilicity and good dispersibility, especially in aqueous solution, it shows significant viscosity adjustment ability, so it is widely used in industry, food, medicine, cosmetics and other fields.
1. Tsanangudzo uye kukurudzira zvinhu zveCMC kupararira
Kupararira kweCMC kazhinji kunoreva kugona kwayo kuparadzira nekunyungudika mumvura kana mamwe mashirimo. Cellulose pachayo haina kusunganidzwa mumvura, asi mushure mekugadziridzwa, cmc ine yakanaka mvura yekurudyi. Kupararira kwayo kunokanganiswa nezvinhu zvakawanda, kunyanya kusanganisira zvinotevera:
MaElecular uremu: uremu hwemanyorerwe eCMC zvakananga zvinobata zvinobata uye kuparadzaniswa. Huremu hwepamusoro hunorema hunoreva hombe molecular chimiro, izvo zvinogona kutungamira kupaza zvishoma uye zvinogona kukanganisa visikopa yemhinduro yekupedzisira, nekudaro ichikanganisa zvinoparadzanisa. CMC ine yakaderera molecular uremu ine kurarurirwa zviri nani mumhinduro, asi iko kukanganisa kwayo kwakashata.
Degree reCarboxyMethylation: Kupararira kweCMC kwakanyatsoenderana nedhigirii rayo rekugadziridzwa kwemakemikari. Dhigirii rakakwirira remotokari rinoreva kuti mamwe mapoka ehydropilic (-coh) mumorekuru, ayo anogona kuumba hukama hweHydrogen uye nekuvandudza iyo solubility uye kuvharidzirwa kweCMC. Pane kusapindirana, degree rakaderera reCarboxyMethylation inogona kutungamira mukupararira kweCMC, kana kunyange kuomerwa mukunyungudika.
PH Kukosha kweMhinduro: Iyo Solubility uye Kupararira kweCMC inogona kusiyana zvakanyanya pane zvakasiyana pH KESI. Mune acidic kana isina kwaakarerekera nharaunda, cmc inowanzoparadzanisa; Ndichiri pasi peAlkaline Mamiriro ezvinhu, CMC's Hydrofiromity inowedzerwa, iyo inogona kuwedzera iyo visikopo yeCMC mhinduro yeCMC uye kukanganisa kuparadzaniswa kwaro. Naizvozvo, kugadziridzwa kwePP kukosha kwakakosha kune kuaparadzikwa kweCMC.
Ionic Simba: Iyo ION yekuvhara mumhinduro ichaitawo zvinoparadzaniswa neCMC. Kukwirira kwakanyanya kweMaronda kana zvimwe zvinhu zveIonized zvinogona kuderedza iyo solubility uye kuparadzaniswa nekupindirana neyakaipisisa nemamolecules. CMC inoratidzira kupararira kwakanaka pasi pasi peSiomic Ionic Simba.
Tembiricha: tembiricha zvakare ine imwe mhedzisiro pane kuvapararira kweCMC. Kazhinji, kuwedzera kwe tembiricha kuchakurumidza kudzora maitiro eCMC uye kuvandudza kupararira. Nekudaro, zvakanyanyisa kupisa zvinogona kukonzera kuputsa kana kushungurudzika kweiyo cmc molecular ketani, iyo inoshanduka inokanganisa kugadzikana kwayo uye kupararira maitiro. Naizvozvo, kudzora zvine musoro kwekudziya kwakakosha mukuparadzaniswa kweCMC.
2. Masvondo ekushandisa eCMC kupararira
Kupararira kwakanakisa kweCMC kunoita kuti ishandiswe zvakanyanya muminda yakawanda. Izvi zvinotevera ndedzimwe nzvimbo huru dzekushandisa:
Mbira uye pendi: Mugadziriro yekugadzirira yejasi uye pendi, cmc, seyakakwenenzverwa uye inopararira, inogona kukanganisa mari uye zvimwe zvimedu zvevakasimba uye kudzivirira kubva pakugadzirisa. Nekuda kweiyo yakasimba hydrophicity, cmc inogona kuridza ruvara rwakanakisa muzvinyorwa zvemvura-zvakavakirwa mvura, nekudaro uchivandudza kugadzikana uye kufanana kwekuvhara.
Indasitiri yeChikafu: CMC, seanotenda uye STabilizer, inoshandiswa zvakanyanya muindasitiri yechikafu, yakadai sejelly, ice cream, pipi nechingwa. Muchikafu, CMC inobatsira kuvandudza kugadzirwa uye kuravira kwechigadzirwa, uku uchirangarira yunifomu yekusanganisa kwezvinhu zvisina kugadzirwa nekuvandudza kuriparadzaniswa.
Kugadzirira kwechechi: Muindasitiri inoshandiswa seyekupararira uye stabilizer mukugadzirira kwemvura, mishonga yemishonga, madonhwe emaziso, kumiswa uye kumwe kugadzirira. Kupararira kwayo kwakanaka kunobatsira kuve nechokwadi chekuparadzira yunifomu yezvisikwa zvinodhaka uye kugadzirisa kusimba kwekushanda kwezvinodhaka.
Cosmetic Indasitiri: CMC iri zvakare inoshandiswa zvakanyanya mune cosmetics, kunyanya mune zvigadzirwa zvakadai sosi sosi, kirimu, shampoos uye ges jege. Kupararira kwayo kunogona kuve nechokwadi chekuparadzirwa yunifomu yezvinonwiwa uye kugadzirisa kugadzikana uye kushandisa ruzivo rwezvigadzirwa.
Pepa uye zvinyorwa: CMC inowanzoshandiswa mukugadzira process yepepa uye zviyero seyekunyora sedhickener uye inopararira kuti uvandudze simba uye pfungwa yemukati yepepa. Mukudhinda uye dhayekurira kwemaitiro, CMC inogona kuparadzira dhayi uye pigment kuti ive nechokwadi cheyunifomu yekudya.
3. Optimization zano reCMC Kupararira kweCMC
Kuti uwedzere kuenderera mberi nekuvandudza kuparadzirwa kweCMC, iyo inotevera nzira dzekuongororwa dzinogona kutorwa:
Gadzirisa uremu uye carboxymethylation degree reCMC: Nekudzora iyo molecular uremu uye carboxymethyation degree reCMC, kupararira kwayo mune dzakasiyana zvikumbiro kunogona kugadziriswa. Semuenzaniso, yepamusoro molecular uremu uye yakakwirira mwero weCarboxyMethylation inogona kubatsira kuvandudza kuurumbidzwa kweCMC mumhedzisiro mhinduro.
Kushandisa kweSurfacticts: Mune zvimwe zvekushandisa, kuwedzera huwandu hwakakodzera hwevarasikodzi dzinogona kuvandudza kuurumbidzwa kweCMC, kunyanya kana uchibata nemafuta-emvura zvisingaite zvinhu. Surfactants inogona kuderedza kusanzwisisika kwekunetseka uye kusimudzira iyo yekupararira kwemamorita eCMC.
Optimizing Conselution Mamiriro ezvinhu: Kudzora Kunakidza kweCMC Dissolution tembiricha, PH Kukosha uye solvent kusimbisa kunogona kugadzirisa kuparadzirwa kwayo. Semuenzaniso, cmc inowanzo kuve iri nani pane yakadzika tembiricha uye isina kwaakarerekera PP mamiriro.
Kuwedzera nedzimwe zvinopararira: Mune zvimwe zvinoshandiswa zvinoshandiswa, cmc inogona kuwedzerwa pamwe nevamwe vaparidzi kuti vabudise pachena. Semuenzaniso, mamwe manyorerwo makuru manyorerwo polymers kana zvigadzirwa zvechisikigo zvinogona kushanda neCMC kuti uwedzere kuparadzirwa kwayo.
CarboxyMethyl Cellerose ine yakanakisa kupararira uye inoshandiswa zvakanyanya mumakonzo, chikafu, mishonga, cosmetics uye mamwe maindasitiri. Kupararira kwayo kunokanganiswa nezvinhu zvakawanda zvakadai senge zvinyoro-nyoro uremu, degree rearboxymethylation, ph kukosha, ionic simba uye tembiricha. Kupararira kweCMC kunogona kuwedzeredzwa kuburikidza neakakodzera nzira dzekubhadhara, dzakadai sekugadzirisa suremu uye kushandisa surfers. Sezvo kudiwa kwemaindasitiri kunoenderera mberi nekuwedzera, kucherechedzwa kweCMC kunokanganiswa kuchaenderera mberi nekuwedzera kuti usangane zvinodiwa zvakasiyana siyana.
