I-sodium carboxymethyl cellulose (CMC)

I-CMC iwumkhiqizo osetshenziswa kakhulu futhi olula ku-cellulose ether, eyaziwa ngokuthi “i-MSG yezimboni”.
I-CMC inezici eziningi ezibalulekile, njengokwenza i-viscosity colloid ephezulu, isixazululo, ingcina, ukujiya, ukugeleza, i-emulsification, ukuhlakazeka, ukubumba, ukongiwa kwamanzi, ukuvikela i-colloid, ukwakheka kwefilimu, ukumelana ne-asidi, ukumelana nosawoti kanye nokumelana ne-turbidity, futhi akunangozi ku-physiology. .Ngakho-ke, i-CMC isetshenziswe kabanzi ekudleni, imithi, amakhemikhali nsuku zonke, amafutha, ukwenza iphepha, izindwangu, ukwakhiwa kanye neminye imikhakha.
(1) ukumba nokumbiwa kukawoyela negesi yemvelo, ukumba imithombo kanye neminye imisebenzi
① Udaka oluqukethe i-CMC lungenza udonga lomthombo lube ikhekhe eliyisihlungi elincanyana neliqinile elinokungena kancane, futhi linciphise ukulahleka kwamanzi.
② Ngemva kokuba i-CMC yengezwe odakeni, umshini wokumba ungathola amandla okugunda okuqala amancane, wenze udaka lube lula ukukhulula igesi egoqwe kulo, futhi ulahle imfucumfucu emgodini wodaka ngokushesha.
③ Ukumba udaka kunesikhathi esithile sokuba khona, njengamanye ama-dispersions amisiwe, futhi angaqiniswa futhi anwetshwe yi-CMC.
④ Udaka oluqukethe i-CMC aluvamile ukuthintwa isikhunta, ngakho-ke akudingekile ukugcina ivelu ye-pH ephezulu kanye nokulondoloza.
⑤ I-CMC isetshenziswa njenge-ejenti yokwelapha yokumba uketshezi lokuwasha udaka, olungamelana nokungcoliswa kukasawoti omningi oncibilikayo.
⑥ I-slurry ene-CMC inokusimama okuhle, futhi ukulahlekelwa kwamanzi kungancishiswa ngisho noma izinga lokushisa lingaphezu kuka-150 ℃.
I-CMC ene-viscosity ephezulu kanye ne-high substitution degree ifaneleka udaka olunomthamo ophansi futhi i-CMC enezinga eliphezulu lokushintshanisa nge-viscosity ephansi ifanele udaka olunobuningi obukhulu.I-CMC kufanele ikhethwe ngokuya ngezinhlobo zodaka, izindawo, ukujula komthombo nezinye izimo.
(2) I-CMC isetshenziswa njenge-ejenti yokulinganisa ezimbonini zendwangu nokunyathelisa nezokudaya, futhi isetshenziselwa ukulinganisa ukotini, uboya bukasilika, imicu yamakhemikhali, izindwangu ezihlanganisiwe nezinye izinto eziqinile;
(3) I-CMC ingasetshenziswa njenge-ejenti ebushelelezi nesayizi embonini yamaphepha.Iphepha lingakhuphula amandla okuqina ngo-40% - 50%, i-compressive fracture degree ikhuphuka ngo-50%, futhi ikhono lokuxova likhuphuka izikhathi ezingu-4-5 ngokungeza u-0.1% kuya ku-0.3% CMC.
(4) I-CMC ingasetshenziswa njenge-adsorbent yokungcola lapho yengezwa kumshini wokuwasha wokwenziwa;Ukusetshenziswa kwansuku zonke kwamakhemikhali, njenge-glycerine aqueous solution ye-CMC embonini yokuxubha amazinyo, isetshenziswa njengesisekelo seglue somuthi wokuxubha;Imboni yezemithi isetshenziswa njenge-thickener ne-emulsifier;Isixazululo esinamanzi se-CMC sisetshenziswa njengokuntanta ngemuva kokwanda kwe-viscosity.
(5) ingasetshenziswa njenge-adhesive, i-plasticizer, i-ejenti yokumiswa kanye ne-ejenti yokulungisa i-glaze embonini yobumba.
(6) isetshenziselwa ukwakha ukuthuthukisa ukongiwa kwamanzi namandla
