I-sodium carboxymethyl cellulose (i-CMC-Na ngokufutshane) yinto ebalulekileyo yepolymer enyibilikayo yamanzi, esetyenziswa ngokubanzi kumashishini okutya, amayeza, izithambiso, i-textile, i-papermaking kunye nokwakha. Njengesitye esisetyenziswa ngokuqhelekileyo, isizinzi kunye ne-emulsifier,
1. Ukukhethwa kwezinto eziluhlaza kunye nokulawula umgangatho
Xa ukhetha i-CMC-Na, kufuneka ubeke ingqalelo ekukhetheni iimveliso ezicocekileyo. Iimpawu zomgangatho wemveliso ziquka iqondo lokutshintshwa, i-viscosity, ukucoceka kunye nexabiso le-pH. Iqondo lokutshintsha libhekisa kumxholo wamaqela e-carboxylmethyl kwi-molecule ye-CMC-Na. Ngokubanzi, okukhona iqondo eliphezulu lokufakela endaweni, kokukhona ngcono ukunyibilika. I-Viscosity inquma ukuhambelana kwesisombululo, kwaye ibakala elifanelekileyo le-viscosity kufuneka likhethwe ngokweemfuno zangempela zesicelo. Ukongezelela, qinisekisa ukuba imveliso ayinayo iphunga, akukho kungcola, kwaye ihlangabezana nemigangatho efanelekileyo, efana nebakala lokutya, ibakala leyeza, njl.
2. Iimfuno zomgangatho wamanzi ukulungiselela isisombululo
Xa ulungiselela isisombululo se-CMC-Na, umgangatho wamanzi asetyenzisiweyo ubaluleke kakhulu. Ngokuqhelekileyo kuyafuneka ukuba kusetyenziswe amanzi acocekileyo okanye amanzi adibeneyo ukuphepha impembelelo yokungcola emanzini kwisisombululo se-CMC-Na. Ukungcola okufana nee-ion zetsimbi kunye ne-chloride ion emanzini kunokusabela ngokwekhemikhali kunye ne-CMC-Na, echaphazela ukuzinza kunye nokusebenza kwesisombululo.
3. Indlela yokuchithwa kunye namanyathelo
Ukupheliswa kwe-CMC-Na yinkqubo ecothayo, edla ngokufuneka ukuba yenziwe ngamanyathelo:
Ngaphambi kokumanzisa: Ngaphambi kokuba ungeze i-CMC-Na powder emanzini, kucetyiswa ukuba uyifake kwangaphambili ngexabiso elincinci le-ethanol, ipropylene glycol okanye i-glycerol. Oku kunceda ukuthintela umgubo kwi-agglomerating ngexesha lenkqubo yokuchithwa kunye nokwenza isisombululo esingalinganiyo.
Ukutya okucothayo: Yongeza kancinci i-CMC-Na powder phantsi kweemeko ezivuselelayo. Zama ukuphepha ukongeza inani elikhulu lepowder ngexesha elinye ukuze ugweme ukubunjwa kwamathambo kunye nobunzima bokuchithwa.
Ukuvuselela ngokupheleleyo: Emva kokufaka umgubo, qhubeka uvuselela de uchithe ngokupheleleyo. Isantya esishukumisayo akufanele sikhawuleze ukuthintela ukuveliswa kwamaqamu amaninzi kwaye kuchaphazele ukucaca kwesisombululo.
Ulawulo lobushushu: Ubushushu ngexesha lenkqubo yokuchithwa kunempembelelo ethile kwisantya sokuchithwa. Ngokuqhelekileyo, ubushushu obuphakathi kwe-20°C kunye ne-60°C bufaneleke ngakumbi. Ubushushu obuphezulu kakhulu bunokubangela ukuba isisombululo se-viscosity sehle kwaye sitshabalalise nolwakhiwo lwe-CMC-Na.
4. Ukugcinwa kunye nokuzinza kwesisombululo
Isisombululo esilungisiweyo se-CMC-Na kufuneka sigcinwe kwisitya esitywiniweyo kwaye siphephe ukudibana nomoya ukuthintela ukufunxa ukufuma kunye ne-oxidation. Ngexesha elifanayo, ukukhanya kwelanga kunye nendawo yokushisa ephezulu kufuneka kugwenywe kangangoko kunokwenzeka ukugcina ukuzinza kwesisombululo. Ngexesha lokugcinwa kwexesha elide, isisombululo sinokuwohloka ngenxa yokukhula kwe-microorganisms, ngoko unokuqwalasela ukongeza izigcini ezifana ne-sodium benzoate kunye ne-potassium sorbate xa uyilungiselela.
5. Ukusetyenziswa kunye nonyango lwesisombululo
Xa usebenzisa isisombululo se-CMC-Na, kufuneka uqaphele ukuphepha ukudibanisa ne-acids eqinile kunye neziseko eziqinileyo ukuphepha ukuphendula kweekhemikhali ezichaphazela ukuzinza kunye nokusebenza kwesisombululo. Ukongeza, isisombululo se-CMC-Na siyacaphukisa ulusu kunye namehlo ukuya kwinqanaba elithile, ngoko kufuneka unxibe izixhobo ezifanelekileyo zokukhusela xa usebenzisa, njengeiglavu, iiglavu, njl.
6. Ukhuseleko lokusingqongileyo kunye nokulahlwa kwenkunkuma
Xa usebenzisa i-CMC-Na, kufuneka ubeke ingqalelo kukhuseleko lokusingqongileyo lwenkunkuma. Inkunkuma ye-CMC-Na isisombululo kufuneka iphathwe ngokuhambelana nemimiselo efanelekileyo ukuphepha ukungcoliseka kwendalo. Inkunkuma idla ngokucocwa ngokuthotywa kwezinto eziphilayo okanye ngonyango lwekhemikhali.
Xa ulungiselela isisombululo se-sodium carboxymethyl cellulose, kuyimfuneko ukuqwalasela ngokucophelela kwaye usebenze kwiinkalo ezininzi ezifana nokukhethwa kwezinto eziluhlaza, indlela yokutshatyalaliswa, iimeko zokugcina kunye nonyango lokusingqongileyo. Kuphela phantsi kwesiseko solawulo olungqongqo lwekhonkco nganye isisombululo esilungisiweyo sinokusebenza kakuhle kunye nokuzinza ukuhlangabezana neemfuno zemimandla eyahlukeneyo yesicelo.
