1. Chii chinonzi CMC?
CMC, carboxymethylcellulose, musanganiswa wepolymer unonyungudika nemvura wakagadzirwa kubva kumakemikari ekugadzirisa echisikigo cellulose. Sekuwedzera kwechikafu, KimaCell®CMC ine mvura yakanaka solubility, thickening uye colloidal kugadzikana, uye inoshandiswa zvakanyanya muindasitiri yechikafu. Rimwe remabasa ayo makuru mukugadzirwa kwechingwa nderekuvandudza kuchengetwa kwemvura yechingwa, nekudaro kunowedzera kunaka uye kutsva kwechigadzirwa.
2. Kukosha kwekuchengetedza mwando muchingwa
Kuchengetwa kwemvura kwechingwa chinhu chakakosha pakusarudza kuravira kwayo, kuumbwa uye hupenyu hwesherufu. Kuchengetedza zvakanaka kwemvura kunobvumira:
Chengetedza kupfava: Dzivirira chingwa kubva pakuoma nekuoma nekuda kwekurasikirwa nehunyoro.
Wedzera hupenyu hwesherufu: kuderedza kuchembera kumhanya uye kunonoka kudzoreredza kwe starch.
Inovandudza elasticity uye chimiro: Inoita kuti chingwa chiwedzere kunyungudika uye chisinga tyoke kana uchicheka uye uchitsenga.
Zvisinei, mukugadzirwa kwechokwadi, nekuda kwekushisa kwepamusoro panguva yekubika, hunyoro huri muhupfu huri nyore kubuda, uye mushure mekubika, chingwa chinowanzorasikirwa nekunyorova nekuda kwemamiriro ezvinhu akaoma. Panguva ino, kuwedzera CMC kunogona kuvandudza zvakanyanya kuchengetedza kwemvura kuita kwechingwa.
3. Iyo chaiyo nzira yekuita kweCMC muchingwa
(1) Kuwedzerwa kwemvura uye kuchengetedza mvura
CMC mamorekuru ane nhamba huru yecarboxymethyl inoshanda mapoka. Aya mapoka epolar anogona kuumba hydrogen zvisungo nemamorekuru emvura, nekudaro achivandudza zvakanyanya kusunga kwemvura nekugona kuchengetedza. Munguva yekugadzira chingwa, CMC inogona kubatsira mukanyiwa kutora mvura yakawanda, kuwedzera hunyoro hwemukanyiwa, uye kuderedza kubuda kwemvura panguva yekubika. Kunyangwe panguva yekuchengetedza, CMC inogona kuderedza mvura yekurasikirwa kwechingwa uye kuchengetedza yakapfava manyoro.
(2) Kuvandudza chimiro uye ductility yehupfu
Seyakakora uye colloidal stabilizer, CMC inogona kuvandudza rheological zvimiro zvehupfu. Pakusanganisa mukanyiwa, CMC inogona kuumba chinjikira-yakabatana network chimiro ne starch uye mapuroteni muupfu, nekudaro ichiwedzera mvura-inobata simba remukanyiwa uye kuita kuti mukanyiwa uwedzere elastic uye ductile. Ichi chimiro chinobatsirawo kuvandudza kugadzikana kwemabhuru emhepo panguva yekubika, pakupedzisira kugadzira chingwa chine yunifomu manyorerwo uye yakanaka pores.
(3) Kunonoka kuchembera sitachi
Starch kuchembera (kana retrogradation) ndicho chikonzero chakakosha nei chingwa chinorasikirwa nekupfava kwayo. Mushure mekubika, mamorekuru e starch muchingwa anoronga zvakare kugadzira makristasi, zvichiita kuti chingwa chiome. KimaCell®CMC inogona kunyatso kudzikisira kusimba kwechingwa nekushambadza pamusoro pemamorekuru estarch uye kutadzisa kurongekazve kwemaketani esitashi.
(4) Synergy nezvimwe zvinhu
CMC inoshandiswa pamwe chete nezvimwe zvinowedzera zvekudya (senge glycerin, emulsifiers, nezvimwewo) kuti iwedzere kuwedzera kuchengetwa kwemvura yechingwa. Semuenzaniso, CMC inogona kushanda nema emulsifiers pane bubble chimiro chemukanyiwa kuvandudza kugadzikana kwemabhuru, nekudaro kuderedza kurasikirwa kwemvura panguva yekubika. Uye zvakare, iyo polymer cheni chimiro cheCMC inogona kushanda nema humectants senge glycerin kuchengetedza hunyoro hwechingwa.
4. Mashandisiro eCMC uye matanho ekudzivirira
Mukugadzira chingwa, CMC inowanzowedzerwa kune mukanyiwa muupfu kana yakanyungudika nyika. Iyo chaiyo dosage inowanzoita 0.2% kusvika 0.5% yehupfu hwemhando, asi inoda kugadziridzwa zvinoenderana neformula uye rudzi rwechigadzirwa. Mapoinzi anotevera anofanirwa kucherechedzwa pakushandisa:
Solubility: CMC inofanira kunyungudutswa zvizere kudzivirira kuumbwa kwezvidimbu kana agglomerates mumukanyiwa, zvichikanganisa kuenderana kwekanyiwa.
Kuwedzera huwandu: Kunyanya kushandiswa kweCMC kunogona kuita kuti chingwa chiravire kunamira kana kunyorova, saka huwandu hunoda kudzorwa zvine musoro.
Recipe balance: Iyo synergistic mhedzisiro yeCMC nezvimwe zvinongedzo zvakaita sembiriso, shuga uye emulsifiers zvinogona kukanganisa kusimuka kwechingwa uye magadzirirwo, saka iyo resipi inofanirwa kuvandudzwa kuburikidza nekuyedza.
5. Migumisiro yekushandisa
Nekuwedzera CMC, kuchengetwa kwemvura kwechingwa kunogona kuvandudzwa zvakanyanya. Izvi zvinotevera zvakati wandei zvinowanzoitika:
Kunzwa kwakanyorova kunowedzera mushure mekubika: mukati mechingwa yakanyorova mushure mekucheka, uye nzvimbo yacho haina kuoma uye yakatsemuka.
Optimized kuravira: yakapfava uye yakawedzera elastic kana uchitsenga.
Hupenyu hwesherufu hwakawedzerwa: Chingwa chinoramba chiri chitsva mushure memazuva akati wandei chekuchengetedza patembiricha yekamuri uye chinoomesa zvishoma nekukurumidza.
6. Mafambiro ebudiriro yeramangwana
Sezvo kudiwa kwevatengi kwechisikigo uye hutano hwechikafu kuchiwedzera, KimaCell®CMC dzimwe nzira dzine yakaderera yekuwedzera kana masosi masosi ari kutariswa zvishoma nezvishoma. Nekudaro, seyakakura, yakagadzikana uye inoshanda yekuchengetedza mvura mumiriri, CMC ichine yakakura yekushandisa mukana mukugadzira chingwa. Mune ramangwana,CMCtsvakiridzo yekunatsiridza (sekunatsiridza asidi kuramba kana kusanganisa nemamwe macolloid echisikigo) inogona kuwedzera minda yekushandiswa kwayo.
Kuburikidza nekunwa kwayo kwakanakisa kwemvura, kunyorova uye colloidal kugadzikana zvivakwa, CMC inopa rubatsiro rwakakosha mukuvandudza kuchengetwa kwemvura yechingwa nekuwedzera hupenyu hwayo. Icho chimwe chezvinowedzera zvakakosha muindasitiri yemazuva ano yekubheka.
