I-Methylcellulose (MC) iphuma ku-cellulose ngokwelashwa kwe-methylation futhi inezici zomzimba namakhemikhali eziyingqayizivele. Njengesengezo esisebenzayo esisetshenziswa kabanzi, sidlala indima ebalulekile emikhakheni ehlukahlukene yezimboni, okuhlanganisa izinto zokwakha, ukudla, imithi, izimonyo nezindwangu, njll. Ukuqina kwayo okuhle kakhulu, ukugcinwa kwamanzi, ukubopha, ukwenza ifilimu, i-emulsifying kanye nokuzinzisa imisebenzi yenza i-methylcellulose. isithako esibalulekile ekwandiseni nasekuthuthukiseni ukwakheka kwezimboni.
1. Ukuqina komphumela
Izakhiwo zokujiya ze-methylcellulose ziyenza ibe isithako esibalulekile embonini yokwakha neyokumboza. Embonini yezokwakha, ikakhulukazi ku-samente-based mortar kanye nemikhiqizo ye-gypsum, i-methylcellulose ingakhuphula ngokuphawulekayo ukuvumelana kanye ne-viscosity yefomula, ngaleyo ndlela ithuthukise ukusebenza kwempahla. Ngezinto zokumboza namapende, ukungezwa kwe-methylcellulose kungavimbela ngokuphumelelayo uketshezi ukuthi lungabi uketshezi kakhulu futhi kuthuthukise ukunamathela nokufana kwento enamathelayo.
Indlela yokuqina ikakhulukazi ngokwakhiwa kwesakhiwo senethiwekhi esixazululweni nge-methylcellulose. Amaketanga wamangqamuzana e-methylcellulose asebenzisana ngamabhondi e-hydrogen emanzini ukuze akhe isixazululo nge-viscosity ethile. Lesi sakhiwo senethiwekhi singabamba futhi silungise ama-molecule amanzi, ngaleyo ndlela sandise i-viscosity nokuzinza kwesistimu ye-liquid.
2. Ukugcinwa kwamanzi
Ezintweni zokwakha ezifana nosimende nodaka lwegypsum, izakhiwo zokugcina amanzi ze-methylcellulose zibalulekile. Izinto zokwakha zidinga inani elifanele lomswakamo ukuze libambe iqhaza ekuphenduleni ngesikhathi senqubo yokwelapha. Ukulahlekelwa kwamanzi ngaphambi kwesikhathi kuzoholela ekwelapheni okunganele kwento, ukuncipha kwamandla, noma imifantu phezulu. I-Methylcellulose yakha ifilimu elincanyana ebusweni bento ukuvimbela ukuhwamuka kwamanzi ngokweqile nokuqinisekisa ukuthi usimende, ukhonkolo nezinye izinto zinomswakama owanele phakathi nenqubo yokwelapha, ngaleyo ndlela zithuthukise amandla nokuqina kwazo.
Lo mphumela wokugcina amanzi ubaluleke kakhulu ezindaweni ezomile noma ezinezinga lokushisa eliphezulu, okuvumela i-methylcellulose ukuthi ithuthukise ukusebenza kokwakheka kwezimboni ngaphansi kwezimo zemvelo ezimbi kakhulu.
3. Ukuhlanganisa nokuthuthukisa amandla ezinto ezibonakalayo
Izakhiwo zokubopha ze-methylcellulose nazo zinhle kakhulu ekukhiqizweni kwezimboni. Isibonelo, kuma-adhesive e-tile nezinye izinhlobo zama-ejenti okubambisana, i-methylcellulose ingathuthukisa ukunamathela kokubunjwa, okuvumela ukuthi izinto ezibophezelayo zihambisane kangcono nomsebenzi. Isakhiwo se-molecular chain ye-methylcellulose singasebenzisana ne-matrix ukuze kuthuthukiswe amandla okubopha, ngaleyo ndlela kuthuthukiswe amandla esakhiwo jikelele wento.
Kumapulasitiki aqiniswe nge-fiber-reinforced (FRP), i-methylcellulose ingathuthukisa amandla nokuqina kwezinto eziyinhlanganisela ngesakhiwo sayo esine-fibrous, inikeze okubalulekile amandla okuqina okuphezulu nokumelana nokugqoka, ngaleyo ndlela ithuthukise ukuqina kwayo ezisetshenziswa zezimboni. ucansi.
4. Ukwakhiwa kwefilimu
I-Methylcellulose inekhono elihle lokwenza ifilimu ekuxazululeni, futhi le ndawo isetshenziswe kabanzi emikhakheni eminingi yezimboni. Embonini yokumboza nopende, i-methylcellulose ingakha ifilimu yokuzivikela efanayo eyandisa ukumelana namanzi kanye nokumelana kwamakhemikhali kwezingubo.
Embonini yokudla, i-methylcellulose ibuye isetshenziswe ngokujwayelekile ekuhlanganiseni noma ekwenzeni ifilimu, ikakhulukazi ekufakweni okusha kwezithelo, imifino nokunye ukudla. Ngokwenza ifilimu encane, i-methylcellulose ibambezela ukulahlekelwa umswakama futhi ivikela ukudla endaweni engaphandle.
5. Ukuzinzisa kanye ne-emulsification
I-Methylcellulose ingakwazi ukukhiqiza isisombululo esiphezulu se-viscosity lapho sichithwa emanzini, esinemiphumela yokuzinza kanye ne-emulsifying. Lesi sakhiwo sibaluleke kakhulu ezimbonini ezifana nezingubo zokugqoka, amapende, izimonyo kanye namalungiselelo emithi. Kumapende namapende, i-methylcellulose ingakwazi ukuzinzisa ukusakazeka kwezingulube, ivimbele ukuhlaliswa, futhi ithuthukise ukucwebezela nokufana kwento yokumboza; ekubunjweni kwezimonyo, i-methylcellulose isebenza njenge-emulsifier ukuzinzisa uhlelo oluxubile lwamafutha amanzi nokuvimbela i-Stratification.
Emalungiselelweni okwenziwa kwemithi, i-methylcellulose ivamise ukusetshenziselwa ukujiya kanye nokusimamisa amalungiselelo oketshezi lomlomo futhi njengomthwali wezidakamizwa. I-viscosity yayo kanye nezakhiwo zokwenza ifilimu kungasiza umuthi ukuthi ukhululwe kancane, unwebe isikhathi somphumela wesidakamizwa, futhi uthuthukise i-bioavailability yomuthi.
6. Izakhiwo ze-thermal gelling
Isakhiwo esibalulekile se-methylcellulose ukuziphatha kwayo okushisayo okushisayo, lapho iphenduka ijeli lapho ishiswa. Lesi sici siyenza ingenakuthathelwa indawo kwezinye izinto ezikhethekile zezimboni. Isibonelo, embonini yokudla, i-methylcellulose isetshenziselwa ukucubungula ukudla okunamafutha aphansi. Ijeli elakhiwe ngemva kokushisa linokunambitheka okufana namafutha, okuvumela ukudla okunamafutha aphansi ukugcina ukunambitheka okuhle nokuthungwa. Embonini yezokwakha, lesi sakhiwo se-thermal gelling sithuthukisa ukuqina nokuzinza kwezinto zokwakha ezindaweni ezishisa kakhulu.
7. I-Biocompatibility kanye nobungane bemvelo
I-Methylcellulose, njengenhlanganisela etholakala ngokwemvelo, ine-biocompatibility enhle kanye nobungane bemvelo. Lokhu kuyenza idume kakhulu ekwakhiweni kwezimboni zesimanje, ikakhulukazi ezindaweni ezinezidingo eziphakeme zokuvikela imvelo, njengezakhiwo eziluhlaza, okokunamathela kwemvelo nezinto zokupakisha ezonakele. I-Methylcellulose ingonakaliswa ngokwemvelo, yehlise umthwalo wemvelo futhi ihambisane nomkhuba wezimboni wentuthuko esimeme.
8. Thuthukisa ukusebenza kahle kokucubungula
Emkhiqizweni wezimboni, i-methylcellulose ingathuthukisa ukusebenza kahle kokucubungula. Isibonelo, ezintweni zokwakha, i-methylcellulose ingathuthukisa uketshezi nokugcinwa kwamanzi kwezinto, ngaleyo ndlela ithuthukise ukunethezeka nokusebenza kahle kokwakhiwa; kuzimonyo namalungiselelo emithi, i-methylcellulose ingathuthukisa ukuzinza kwamafomula futhi inciphise imvula. kanye ne-delamination, ngaleyo ndlela andise impilo yeshalofu yomkhiqizo. Lezi zakhiwo zivumela i-methylcellulose ukuthi ithuthukise kakhulu ukusebenza kahle kokukhiqiza ngenkathi ithuthukisa ukwakheka kwezimboni.
Njengesengezo esisebenza ngezinto eziningi, i-methylcellulose isetshenziswa ezimbonini eziningi ezifana nezokwakha, ukudla, imithi, izimonyo, izigqoko, njll. ngenxa yezakhiwo zayo eziningi ezifana nokuqina, ukugcinwa kwamanzi, ukubopha, ukwenza ifilimu, ukuqiniswa, i-emulsification kanye ne-thermal gelling. udlala indima ebalulekile ensimini. Ngeke nje ithuthukise izici ezibonakalayo zokwakheka kwezimboni, kodwa futhi ithuthukise ukusebenza kahle kokukhiqiza futhi ihlangabezane nezidingo zezimboni ezihlukahlukene. Ngesikhathi esifanayo, i-biocompatibility kanye nobungane bemvelo be-methylcellulose futhi kuyenza ibe yinto ekahle ehlangabezana nezidingo zentuthuko esimeme. Ngokusebenzisa ngokunengqondo i-methylcellulose ekwakhiweni kwezimboni, ayikwazi nje ukuthuthukisa ikhwalithi yomkhiqizo, kodwa futhi ikhuthaze inqubekelaphambili nokuthuthukiswa kobuchwepheshe bezimboni.
