4. Isetshenziswa njenge-ejenti yokugaya usimende, i-gypsum kanye ne-lime, i-ejenti egcina amanzi, kanye nengxube enhle kakhulu yezinto zokwakha eziyimpushana.
5. I-Hydroxymethylcellulose isetshenziswa kabanzi njenge-excipient ekulungiseleleni imithi, okuhlanganisa amaphilisi omlomo, ukumiswa kanye namalungiselelo e-topical.
Izakhiwo zayo zifana ne-methyl cellulose, kodwa ngenxa yokuba khona kwe-hydroxyethyl cellulose, kulula ukuhlakazeka emanzini, isisombululo sihambisana kakhulu nosawoti, futhi sinezinga lokushisa eliphakeme lokuhlanganisa.
03. I-Carboxymethyl cellulose
1. Isetshenziselwa ukugaya uwoyela negesi yemvelo, ukumba kahle namanye amaphrojekthi
① Udaka oluqukethe i-CMC lungenza udonga lomthombo lube ikhekhe eliyisihlungi elincanyana neliqinile elikwazi ukungena kalula, linciphise ukulahlekelwa kwamanzi.
② Ngemva kokwengeza i-CMC odakeni, umshini wokumba ungathola amandla okugunda okuqala aphansi, ukuze udaka lukhulule kalula igesi egoqwe kulo, futhi ngesikhathi esifanayo, imfucumfucu ingalahlwa ngokushesha emgodini wodaka.
③ Ukumba udaka, njengokunye ukumiswa nokuhlakazeka, kunokuphila kweshalofu elithile. Ukwengeza i-CMC kungayenza izinze futhi kwelule impilo yeshalofu.
④ Udaka oluqukethe i-CMC aluvamile ukuthintwa isikhunta, ngakho-ke kufanele lugcine inani le-pH ephezulu, futhi akudingekile ukusebenzisa izilondolozi.
⑤ Iqukethe i-CMC njenge-ejenti yokwelapha yokumba uketshezi olukhipha udaka, olungamelana nokungcoliswa kukasawoti omningi oncibilikayo.
⑥ Udaka oluqukethe i-CMC lunozinzo oluhle futhi lunganciphisa ukulahlekelwa kwamanzi ngisho noma izinga lokushisa lingaphezu kuka-150°C.
I-CMC ene-viscosity ephezulu kanye nezinga eliphakeme lokushintshwa lilungele udaka olunomthamo ophansi, futhi i-CMC ene-viscosity ephansi kanye nezinga eliphezulu lokushintshwa lifanele udaka olunomthamo omkhulu. Ukukhethwa kwe-CMC kufanele kunqunywe ngokuvumelana nezimo ezahlukene ezifana nohlobo lodaka, isifunda, nokujula kwemithombo.
2. Isetshenziswa ezimbonini zendwangu, zokuphrinta nezokudaya. Embonini yendwangu, i-CMC isetshenziswa njenge-ejenti yokulinganisa ukulinganisa kwentambo kakotini, uboya besilika, i-chemical fiber, i-blended nezinye izinto eziqinile;
3. Isetshenziswa embonini yephepha i-CMC ingasetshenziswa njenge-ejenti yokushelela iphepha kanye ne-ejenti yokulinganisa embonini yephepha. Ukwengeza u-0.1% kuya ku-0.3% we-CMC ku-pulp kungakhuphula amandla okuqinile ephepha ngo-40% kuya ku-50%, kukhuphule ukumelana nokuqhekeka ngo-50%, futhi kwandise impahla yokuxova izikhathi ezingu-4 kuya kwezi-5.
4. I-CMC ingasetshenziswa njenge-adsorbent yokungcola uma yengezwe kuzinto zokwenziwa zokuhlanza; amakhemikhali nsuku zonke njengemboni yokuxubha amazinyo e-CMC glycerol solution aqueous isetshenziswa njengesisekelo somuthi wokuxubha izinsini; imboni yezemithi isetshenziswa njenge-thickener kanye ne-emulsifier; Isixazululo esinamanzi se-CMC sisetshenziswa njengentanta ngemva kokuqina Kwezimayini nokunye.

6. Isetshenziswa ekwakheni ukuthuthukisa ukugcinwa kwamanzi namandla
7. Kusetshenziswa embonini yokudla. Imboni yezokudla isebenzisa i-CMC enezinga eliphezulu lokushintshwa njengesithako sika-ayisikhilimu, ukudla okusemathinini, ama-noodle asheshayo, kanye nesiqinisi segwebu likabhiya. I-Thickener, i-binder.
8. Imboni yemithi ikhetha i-CMC ene-viscosity efanele njenge-binder, i-ejenti ehlakazayo yamaphilisi, kanye ne-ejenti emisiwe yokumiswa, njll.
04. Methylcellulose
Isetshenziswa njenge-thickener yezinto ezinamathelayo ezincibilika emanzini, njenge-neoprene latex.
Ingasetshenziswa futhi njenge-dispersant, emulsifier kanye ne-stabilizer ye-vinyl chloride kanye ne-styrene suspension polymerization. I-MC ene-DS=2.4～2.7 iyancibilika ku-polar organic solvent, engavimbela ukushibilika kwe-solvent (ingxube ye-dichloromethane ethanol).
