Uyini umehluko phakathi kwe-carboxymethylllose (CMC) ne-polyanionic cellulose (PAC)?

I-Carboxymethyl Cellulose (CMC)na-polyanionic cellulose (PAC)zingama-cellulose ama-cellulose decivatives amabili ajwayelekile, asetshenziswa kabanzi emikhakheni eminingi, ikakhulukazi ku usimende, uphethiloli, ukudla kanye nemithi yezimboni. Umehluko wabo omkhulu uboniswa ekwakhiweni kwamangqamuzana, ukusebenza, insimu yohlelo lokusebenza nasekusebenzeni.

1. Umehluko esakhiweni samangqamuzana

I-Carboxymethyl Cellulose (CMC) iyinto etholwayo etholwe ngethula amaqembu e-carboxymethyl (-ch2cooh) e-cellulose molecule ngokuphendula kwamakhembu. Isakhiwo saso singaletha amaqembu athile noma amaningi e-carboxymethyl ezikhundleni ezithile ze-hydroxyl e-cellulose nge-carboxmethylation reaction. I-CMC ivame ukuvela njengofulawa omhlophe noma omncane ophuzi, ongakha isixazululo se-colloidal esobala noma esincanyana ngemuva kokuchithwa emanzini.

I-Polyanionic Cellulose (PAC) itholakala ngokulungiswa kokuguqulwa kwamakhemikhali njenge-phosphorylation kanye nokuthezeka kwe-cellulose. Ngokungafani ne-KimaCell®cmc, amaqembu e-Aniosc (anjengamaqembu e-phosphate noma amaqembu e-phosphate ester) angeniswa ekwakhekeni kwamangqamuzana eKimaCell®PAC, ngakho-ke kukhombisa izici ze-anionic eziqinile kukhambi lamanzi futhi kungakha ezinye izinto ze-cationic. I-PAC imvamisa i-powder emhlophe noma elula enamanzi amahle e-solubility yamanzi nokuvunywa okuphezulu kune-cmc lapho ichithwa.

2. Umehluko emisebenzini kanye nokwenza

Ukusebenza kwe-CMC:

Izakhiwo ezihlanganayo neze-gelling: I-CMC ingakhulisa kakhulu ukubonwa kwesixazululo kwikhambi elinamanzi futhi liyi-ejenti enhle kakhulu. Umphumela wayo wokuqina uqhamuka ikakhulu ku-hydration phakathi kwamaketanga ama-moleksor kanye nomphumela wecala lamaqembu e-carboxylmethyl kulo.

I-Emulsation kanye nokuzinza: I-CMC ine-emulsation enhle futhi ingasetshenziswa njenge-emulsifier ekudleni nasezimonyo.

I-Adhesion: I-CMC inokunamathelisa okuthile, okungathuthukisa ukunamathela nokugcinwa kwamanzi kwezinto zokwakha futhi kusetshenziswa kabanzi emasimini kawoyela, ukwakhiwa kanye nezinye izimboni.

I-SOLUBILINIME YAMANZI

Ukusebenza kwe-PAC:

I-Polymer ishaja inkemba: I-PAC ine-anionic acnionic ukushaja, okuvumela ukuthi kunqamule ukuxhumanisa noma kuyinkimbinkimbi ngezinto ze-cationers ezifana ne-polymers nama-aqueter shadow efferemu, ekhombisa umphumela onamandla wokwelashwa kwamanzi.

Ukulungiswa kwe-Viscosity: Uma kuqhathaniswa ne-CMC, isisombululo samanzi se-PAC sinokubonakala okuphezulu futhi singasetshenziswa njengoMlawuli we-Rheological ekukhiqizeni uwoyela kanye nokushayela uketshezi lokukhiqiza uketshezi.

Ukuqina kwe-Hydrolysis: I-PAC inokuqina okuhle kwe-hydrolysis kumanani ahlukile we-PH, ikakhulukazi ezindaweni ezine-acidic, futhi kungagcina ukusebenza okuqinile, ngakho-ke kusetshenziswa kabanzi ekukhiqizeni uwoyela we-acidic.

I-Floccution: I-PAC ivame ukusetshenziswa embonini yelashwa yamanzi futhi ingashintshanisa ngempumelelo izinhlayiya ezimisiwe emanzini, okusiza ukuhlanza imizimba yamanzi.

3. Izindawo ezikhulu zohlelo lokusebenza

Ukusetshenziswa kwe-CMC:

Imboni yokudla: I-CMC isetshenziswa kabanzi ejelly, u-ayisikhilimu, izinkokhelo kanye neminye imikhiqizo njenge-swerener, stabilizer kanye emulsifier. Kungathuthukisa ukuqina nokunambitheka komkhiqizo.

Imboni yezemithi: I-CMC isetshenziswa emalungiseleleni amakhambi njenge-ejenti eyakha ifilimu ne-ejenti yokukhishwa okuqhubekayo ukusiza ukukhululwa kancane kwezidakamizwa emzimbeni. Ngaphezu kwalokho, isetshenziswa futhi kwimikhiqizo efana namaconsi eso noketshezi lomlomo.

Imboni yephepha nendwangu: ekukhiqizeni amaphepha, i-KimaCell®cmc isebenza njengoMkhulu kanye nomswakama ukuthuthukisa ubushelelezi obukhona namandla ephepha; Embonini yezindwangu, i-CMC isetshenziswa ekuhlakazeni udayi kanye nezinqubo zokudaya.

Ukushayela uwoyela: I-CMC isebenza njengesikhulu ekudleni uketshezi ukwandisa ukubonwa kodaka futhi kuthuthukise i-RHEOLOGY ngesikhathi sokumba.

Ukusetshenziswa kwe-PAC:

Ukukhishwa kwamafutha: I-KimaCell®PAC isebenza njengomlawuli we-Rheology kanye nokuthambisa okugcotshwa ngowoyela kanye nokukhishwa kwegesi, okungathuthukisa ngempumelelo ukusebenza koketshezi futhi kunciphise ukungqubuzana nokubonakala.

Ukwelashwa kwamanzi: I-PAC ivame ukusetshenziswa ekwelashweni kwamanzi amdaka nasekuphuzeni amanzi okuhlanza amanzi, futhi ingasusa ngempumelelo udaba olumisiwe, izinsimbi ezisindayo namagciwane emanzini. Kusetshenziswa kabanzi ezitshalweni zokwelashwa kwendle zasemadolobheni.

Imboni Yezokwakha: I-PAC isebenza njengomuntu ophikisayo kasimende ukuguqula uketshezi nokuvunywa kukasimende slurry nokwenza ngcono ukusebenza kokwakha.

Imboni yendwangu: I-PAC ingasetshenziswa njengendlela yokudaya ezayo ukuthuthukisa ukungafani kanye nokushesha kombala kwamadayi.

Ukuqhathanisa kwe-4.Pormance

Cmna-Isinyathelozingama-cellulose amabili avela ezingxenyeni ezahlukahlukene zamakhemikhali nemisebenzi. I-CMC ibonakala ikakhulukazi ngokuqina kwayo, i-eculsible and limialing Properties futhi isetshenziswa kabanzi ekudleni, umuthi, amaphepha kanye nezimboni zezindwangu; Ngenkathi i-PAC isetshenziswa kabanzi emikhakheni yokukhishwa kwamafutha kanye nokwelashwa kwamanzi ngenxa yobukhulu bayo obukhulu bokulimala, ukuqina kwamanzi okuhle nokusebenza kwamanzi. Zombili zinezinzuzo zazo ekusebenzeni nasekusetshenzisweni, kanye nokukhethwa kwazo okusetshenziselwa ukusetshenziswa ngokuvamile kuya ngezidingo ezithile zesicelo kanye nemvelo yokusebenzisa.
