Ukusetyenziswa kweCarboxymethyl Cellulose Sodium njenge-Agent yokuGcinwa kwaManzi kwiiCoatings

ICarboxymethyl cellulose sodium (CMC) yipolymer enyibilikayo emanzini ephuma kwiselulosi esetyenziswa kakhulu kwizicelo ezahlukeneyo zemizi-mveliso, kubandakanya neengubo.Kushishino lokugquma, i-CMC isetyenziswa ikakhulu njenge-arhente yokugcina amanzi ngenxa yokukwazi ukufunxa nokugcina amanzi.Kweli nqaku, siza kuxoxa ngokusetyenziswa kwe-CMC njenge-arhente yokugcina amanzi kwiingubo.

Indlela yokuGcina Amanzi ye-CMC kwiiNgxoxo

Umsebenzi oyintloko we-CMC njenge-arhente yokugcina amanzi kwiingubo kukufunxa nokugcina amanzi ekuqulunqweni.Xa ifakwe kwi-coating formulation, i-CMC inokukhupha amanzi kwaye yenze i-gel-efana nesakhiwo esinokubamba iimolekyuli zamanzi.Olu lwakhiwo olufana nejeli lwenziwa ngenxa yokusebenzisana kwamaqela e-carboxyl kwi-CMC kunye neamolekyuli zamanzi ngokusebenzisa i-hydrogen bonding.Oku kubangela ukwanda kwe-viscosity ye-coating formulation, enceda ukunciphisa inani lamanzi aphuphumayo ngexesha lokumisa.

Ukusetyenziswa kwe-CMC njenge-Arhente yoGcino lwaManzi kwiiNgqungquthela

1. Iipeyinti ezisekelwe emanzini: I-CMC isetyenziswa ngokubanzi kwiipeyinti ezisekelwe emanzini njenge-arhente yokugcina amanzi.Iipeyinti ezisekelwe emanzini zenziwe ngeepesenti eziphezulu zamanzi, ezinokuphuma zibe ngumphunga ngexesha lokumisa, okukhokelela kwiziphene ezifana nokuqhekeka, ukukhupha, kunye nokunciphisa.I-CMC inokunceda ekunciphiseni ubungakanani bamanzi aphuphumayo ngokufunxa nokugcina amanzi ekuyilweni.Oku kubangela ifilimu yepeyinti ezinzileyo kunye nefanayo.
2. I-Emulsion Paints: Ipeyinti ye-emulsion luhlobo lwepeyinti esekelwe kumanzi equkethe i-pigments engenamanzi kunye nezibophelelo.I-CMC isetyenziswa kwiipeyinti ze-emulsion njenge-ejenti yokuqina kunye nokugcina amanzi.Ukongezwa kwe-CMC kwiipende ze-emulsion kunokuphucula i-viscosity kunye nokuzinza kokuqulunqwa, okukhokelela kwifilimu yepeyinti efanayo kunye neyomelele.
3. Izongezo zokugquma: I-CMC ikwasetyenziswa njengezongezo zokwaleka ukuphucula ukugcinwa kwamanzi kwezinye iifomyulo zokugquma.Umzekelo, i-CMC inokongezwa kwiingubo ezisekelwe kwisamente ukuphucula ukugcinwa kwamanzi kunye nokusebenza.Ukongezwa kwe-CMC kunokunciphisa ukubunjwa kweentanda ze-shrinkage kwiingubo ezisekelwe kwisamente.
4. Iingubo zokuthungwa: Iingubo zokuthungwa zisetyenziselwa ukudala umgangatho owenziwe kwiindonga kunye nezinye iindawo.I-CMC isetyenziswa kwiingubo zokuthungwa njengento engqindilili kunye ne-arhente yokugcina amanzi.Ukongezwa kwe-CMC kwiingubo zokuthungwa kunokuphucula i-viscosity yabo kunye nokusebenza, okukhokelela kumphezulu ofanayo kunye nokuqina.

Iinzuzo zokusebenzisa i-CMC njenge-Arhente yoGcino lwaManzi kwiiNgxoxo

1. Ukuphuculwa kokuSebenza: I-CMC inokuphucula ukusebenza kweengubo ngokunciphisa umthamo wamanzi aphuphumayo ngexesha lokumisa.Oku kubangela ifilimu yokwambathisa efanayo kunye neyomeleleyo.
2. I-Adhesion eyomeleziweyo: I-CMC inokuphucula ukunamathela kweengubo ngokuphucula i-viscosity yabo kunye nokusebenza.Oku kubangela ifilimu yokugqoka ezinzileyo kunye nefanayo ehambelana kakuhle ne-substrate.
3. Ukonyuka kokuqina: I-CMC inokunyusa ukuqina kweengubo ngokunciphisa ukubunjwa kweziphene ezifana nokuqhekeka, ukuxobula, kunye nokushwabana.Oku kubangela ifilimu yokwambathisa efanayo kunye neyomeleleyo enokumelana noxinzelelo lokusingqongileyo.
4. Ixabiso elisebenzayo: I-CMC yi-arhente yokugcina amanzi engabizi kakhulu enokuthi ifakwe ngokulula kwiifomyula zokugquma.Ukusetyenziswa kwe-CMC kunokuncedisa ekunciphiseni ubungakanani bamanzi afunekayo kwiingubo, okukhokelela ekunciphiseni iindleko zempahla kunye nemveliso.

Ukuqukumbela

ICarboxymethyl cellulose sodium (CMC) yipolymer eguquguqukayo esetyenziswa ngokubanzi njengearhente yokugcina amanzi kwiingubo.I-CMC inokuphucula ukusebenza, ukunamathela, kunye nokuqina kweengubo ngokunciphisa umthamo wamanzi aphuphumayo ngexesha lenkqubo yokomisa.
