Yintoni umahluko phakathi kweCMC kunye nesitatshi?

I-Carboxymethylcellulose (CMC) kunye nesitashi zombini iipolysaccharides, kodwa zinezakhiwo ezahlukeneyo, iipropati kunye nokusetyenziswa.

Ukwakheka kweemolekyuli:

1. I-Carboxymethylcellulose (CMC):

I-Carboxymethylcellulose yi-derivative ye-cellulose, i-polymer ehambelanayo eyenziwe ngeeyunithi ze-glucose ezidityaniswe ngamabhondi e-β-1,4-glycosidic. Ukuguqulwa kweselulosi kubandakanya ukuqaliswa kwamaqela e-carboxymethyl ngokusebenzisa i-etherification, ukuvelisa i-carboxymethylcellulose. Iqela le-carboxymethyl lenza i-CMC i-soluble yamanzi kwaye inika iipropati ezizodwa ze-polymer.

2. Isitatshi:

Isitashi yi-carbohydrate eyenziwe ngeeyunithi ze-glucose ezidityaniswe yi-α-1,4-glycosidic bonds. Yipolymer yendalo efumaneka kwizityalo esetyenziswa njengendawo yokugcina amandla. Iimolekyuli zesitatshi ngokuqhelekileyo zenziwe ngeendidi ezimbini ze-glucose polymers: i-amylose (amatyathanga athe tye) kunye ne-amylopectin (izakhiwo ze-branched chain).

Iimpawu ezibonakalayo:

1. I-Carboxymethylcellulose (CMC):

Ukunyibilika: I-CMC iyanyibilika emanzini ngenxa yobukho bamaqela e-carboxymethyl.

I-Viscosity: Ibonisa i-viscosity ephezulu kwisisombululo, iyenza ixabiseke kwizicelo ezahlukeneyo ezifana nokulungiswa kokutya kunye namayeza.

Ukungafihli: Izisombululo zeCMC zihlala ziselubala.

2. Isitatshi:

Ukunyibilika: Isitatshi somthonyama asinyibiliki emanzini. Idinga i-gelatinization (ukufudumala emanzini) ukuze inyibilike.

I-Viscosity: I-starch intlama ine-viscosity, kodwa iphantsi ngokubanzi kune-CMC.

Ukungafihli: Iintlama zesitatshi zikholisa ukungafihli, kwaye iqondo lokungafihli lisenokwahluka ngokuxhomekeke kuhlobo lwesitatshi.

umthombo:

1. I-Carboxymethylcellulose (CMC):

I-CMC iqhele ukwenziwa ngeselulosi ukusuka kwimithombo yezityalo efana nentlaka yomthi okanye umqhaphu.

2. Isitatshi:

Izityalo ezifana nombona, ingqolowa, iitapile kunye nerayisi zityebile kwistatshi. Sesona sithako siphambili ekutyeni okuninzi okusisiseko.

Inkqubo yeMveliso:

1. I-Carboxymethylcellulose (CMC):

Ukuveliswa kwe-CMC kubandakanya ukusabela kwe-etherification ye-cellulose kunye ne-chloroacetic acid kwi-alkaline medium. Oku kusabela kukhokelela ekutshintshweni kwamaqela e-hydroxyl kwi-cellulose kunye namaqela e-carboxymethyl.

2. Isitatshi:

Ukutsalwa kwesitatshi kubandakanya ukwaphula iiseli zezityalo kunye nokubeka bucala iigranules zestatshi. Isitashi esikhutshweyo sinokungena kwiinkqubo ezahlukeneyo, kubandakanywa ukuguqulwa kunye ne-gelatinization, ukufumana iipropati ezifunwayo.

Injongo kunye nokusetyenziswa:

1. I-Carboxymethylcellulose (CMC):

Ishishini lokutya: I-CMC isetyenziswa njenge-thickener, stabilizer kunye ne-emulsifier ekutyeni okwahlukeneyo.

I-Pharmaceuticals: Ngenxa yokubophelela kunye nokuqhekeka kwayo, ifumana ukusetyenziswa kwimixube yamayeza.

I-Oil Drilling: I-CMC isetyenziswa kwi-oyile yokwemba ulwelo ukulawula i-rheology.

2. Isitatshi:

Ishishini lokutya: Isitatshi sesona sixhobo siphambili sokutya okuninzi kwaye sisetyenziswa njenge-ejenti yokuqina, i-gelling agent kunye ne-stabilizer.

Ishishini lelaphu: Isitatshi sisetyenziswa ekulinganisweni kwelaphu ukunika ukuqina kwelaphu.

Ishishini lephepha: Isitatshi sisetyenziselwa ukwenza iphepha ukwandisa amandla ephepha kunye nokuphucula iimpawu ezingaphezulu.

Nangona i-CMC kunye nesitashi zombini zi-polysaccharides, zineeyantlukwano ekubunjweni kweemolekyuli, iipropati zomzimba, imithombo, iinkqubo zokuvelisa kunye nokusetyenziswa. I-CMC iyanyibilika emanzini kwaye ine-viscous ephezulu kwaye ihlala ikhethwa kwizicelo ezifuna ezi propati, ngelixa isitashi sisixhobo se-polysaccharide esisetyenziswa ngokubanzi kumashishini okutya, amalaphu namaphepha. Ukuqonda lo mahluko kubalulekile ekukhetheni i-polymer efanelekileyo kumashishini athile kunye nokusetyenziswa kwezorhwebo.
