I-Methylcellulose iphuma ku-cellulose evamile esetshenziswa kabanzi kwezokwelapha, ukudla kanye nezimboni. Kuyi-polymer encibilika emanzini ikakhulukazi eyenziwe nge-cellulose yezitshalo zemvelo ngokuguqulwa kwamakhemikhali, futhi inezici eziningi eziyingqayizivele, ezifana nokujiya, i-gelling, ukumiswa, ukwakhiwa kwefilimu nokugcinwa kwamanzi.
Izimpawu kanye nokusetshenziswa kwe-methylcellulose
I-Thickener and gelling agent: Embonini yokudla, i-methylcellulose ivame ukusetshenziswa njenge-thickener kanye ne-gelling agent ukusiza ukuthuthukisa ukuthungwa nokunambitha komkhiqizo. Isibonelo, emikhiqizweni efana ne-ayisikhilimu, ujamu kanye nokugqoka isaladi, i-methylcellulose inganikeza i-viscosity enhle futhi ithuthukise ukuzinza komkhiqizo.
Abathwali bezidakamizwa kanye nabasizayo: Embonini yezemithi, i-methylcellulose ivamise ukusetshenziswa njengesamukeli sezidakamizwa, njenge-binder kanye nesigcwalisi samaphilisi. Ingasetshenziswa futhi njenge-ejenti yokukhululwa okuqhubekayo kwesidakamizwa ukulawula izinga lokukhululwa komuthi futhi kuqinisekiswe ukuzinza nokuqina komphumela wesidakamizwa.
Isicelo ezintweni zokwakha: Emkhakheni wezinto zokwakha, i-methylcellulose isetshenziswa njenge-ejenti yokuqina kanye ne-ejenti yokugcina amanzi kusimende, i-gypsum nama-coatings ukuze kuthuthukiswe ukusebenza kokwakhiwa nokuqina kwempahla.
Umehluko phakathi kwe-methylcellulose nama-antifoaming agents
Ama-Antifoaming agents ayikilasi lamakhemikhali asetshenziselwa ukucindezela noma ukuqeda amabhamuza oketshezini, futhi avame ukutholakala ekucubunguleni ukudla, emithini yemithi, kwizimonyo, ekwenzeni amaphepha, kumakhemikhali nasekwelashweni kwamanzi. Ama-Antifoaming agents ngokuvamile asebenza ngokunciphisa ukungezwani okungaphezulu koketshezi ukuvimbela ukwakheka kwegwebu, noma ngokukhuthaza ukuwa ngokushesha kwegwebu elakhiwe. Ama-antifoaming agents avamile ahlanganisa amafutha abicah, ama-polyethers, ama-fatty acid esters, nezinhlayiya ezithile eziqinile, njenge-silicon dioxide.
Kodwa-ke, i-methylcellulose ayiyona i-ejenti ye-antifoaming ngokwemvelo. Nakuba i-methylcellulose ingakha isixazululo se-viscous lapho incibilika emanzini, futhi i-viscosity yalesi sixazululo ingase ithinte ukwakheka kwegwebu kwezinye izimo, ayinayo indawo esebenzayo ye-antifoaming agents ejwayelekile. Ngamanye amazwi, umsebenzi oyinhloko we-methylcellulose ukuthi isebenza njenge-thickener, i-gelling agent, i-suspending agent, njll., kunokuba isetshenziswe ngokuqondile ukucindezela noma ukuqeda igwebu.
Ukudideka okungenzeka kanye namacala akhethekile
Nakuba i-methylcellulose ingeyona i-ejenti ye-antifoaming, kwezinye izinhlobo ezithile noma imikhiqizo, ingase ithinte ngokungaqondile ukuziphatha kwegwebu ngenxa yomphumela wayo wokujiya kanye nezici zesixazululo. Isibonelo, kwezinye izinhlobo zokudla noma izidakamizwa, i-viscosity ephezulu ye-methylcellulose ingase ikhawulele ukwakheka kwamabhamuza noma ibangele ukuthi amabhamuza awakhe ahlakazeke ngokushesha. Kodwa-ke, lo mphumela awukuvumeli ukuthi uhlukaniswe njenge-ejenti ye-antifoaming ngoba indlela yayo eyinhloko yokusebenza ihluke kakhulu kumakhemikhali kanye nendlela yokusebenza yama-antifoaming agents.
I-Methylcellulose iyi-derivative ye-cellulose esetshenziswa kabanzi enemisebenzi eminingi, kodwa ayithathwa njenge-antifoaming agent. Nakuba kungase kube nomthelela ekuziphatheni okukhihliza amagwebu ezimeni ezithile ezithile, lokhu akuhlanganisi ukusetshenziswa kwakho okuyinhloko noma indlela yokwenza. Ama-Antifoaming agents ngokuvamile anomsebenzi othize wangaphezulu kanye nekhono lokulawula igwebu, kuyilapho i-methylcellulose isetshenziselwa ukuqina, ukugaya, ukumiswa kanye nokugcinwa kwamanzi. Ngakho-ke, uma usebenzisa i-methylcellulose, uma umphumela ocacile we-antifoaming udingeka, i-ejenti ekhethekile ye-antifoaming kufanele ikhethwe ukuze isetshenziswe ngokuhlangene.
