Ukusetyenziswa kwe-CMC kwiingubo
CMC,isodiyam carboxymethyl cellulose, inoluhlu olubanzi lwezicelo kwishishini lokugquma, ngokuyintloko isebenza njenge-thickener, i-stabilizer, kunye ne-film-forming aid, idlala indima ebalulekileyo ekuphuculeni ukusebenza kwe-coating. Apha ngezantsi lucazululo oluneenkcukacha lwezicelo ze-CMC kwishishini lezogquma:
1. Isiphumo sokutyeba
I-CMC, i-compound ye-polymer yendalo enyibilikayo yamanzi, inokwandisa ngokufanelekileyo i-viscosity ye-coatings kunye nokulawula iimpawu zabo ze-rheological, ukwenza iingubo zibe lula kwaye kulula ukuzisebenzisa. Ngokulawula ubungakanani be-CMC eyongeziweyo, umntu unokuhlengahlengisa ngokuchanekileyo ukuhambelana kwepeyinti ye-latex, ngaloo ndlela ephucula ukusebenza kwawo kwesicelo, ukunciphisa ukuthontsiza, ukuphucula ukusebenza kakuhle kolwakhiwo, kunye nokuqinisekisa ukugquma.
2. Isiphumo sokuzinzisa
Ii-pigments kunye nezihluzi kwiingubo zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala nje! Ukongezwa kwe-CMC kunokuphucula kakhulu ukuzinza kweengubo, ukuthintela ukuhlaliswa kwee-pigments kunye nezigcwalisi, kunye nokugcina iingubo ezifanayo kunye nokuhambelana ngexesha lokugcinwa kunye nokusetyenziswa. Ngokukodwa ngexesha lokugcinwa kwexesha elide, isiphumo sokuzinzisa se-CMC sibaluleke kakhulu. Isakhiwo sothungelwano esenziwe yi-CMC sinokuthintela ngokufanelekileyo ukuhlaliswa kwee-pigments kunye nezizaliso, ukugcina ukusabalalisa kunye nokufana kweengubo.
3. Impembelelo yoNcedo lweFilimu
I-CMC idlala indima encedisayo kwinkqubo yokwenziwa kwefilimu yokwaleka, isenza ukuba i-coating yenziwe ixinene kwaye igudileyo emva kokomisa. Oku akuphuculi nje kuphela umgangatho wembonakalo yokugquma, njengokunciphisa amanqaku ebrashi kunye nemiphumo ye-orenji ye-peel, kodwa iphakamisa ukunyanzeliswa kwengubo, ukumelana nokuguga, kunye nokuxhathisa kwamanzi, ngaloo ndlela ukwandisa ubomi benkonzo yokugquma.
4. Ukusebenza kokusingqongileyo
Ngokunyuka okuqhubekayo kwiimfuno zokusingqongileyo, iingubo ezisekelwe emanzini ziye zaba yinto eqhelekileyo kwiimarike.CMC, njenge-additive-friendly coating additive, ayinayo izinto ezinobungozi kwaye ihlangabezana nemigangatho kazwelonke yokukhusela indalo. Ukusetyenziswa kwe-CMC kwiingubo azikwazi ukunciphisa kuphela umxholo we-VOCs (i-volatile organic compounds) kodwa nokuphucula ukusebenza kokusingqongileyo kweengubo, ukuhlangabezana neemfuno zophuhliso oluzinzileyo loluntu lwanamhlanje.
5. Uluhlu olubanzi lwezicelo
I-CMC ayifanelanga kuphela iipeyinti zelatex eziqhelekileyo kunye neengubo ezisekelwe emanzini kodwa nakwiindawo zokugquma ezikhethekileyo ezinje ngeemoto, iingubo zaselwandle, imigangatho yokutya, kunye neengubo zonyango. Kwezi nkalo, i-CMC inokomeleza ngokubonakalayo ukuqina kunye nokunganyangeki kwe-corrosion yengubo, iqinisekisa ukhuseleko kunye nokukhuselwa kokusingqongileyo kweemveliso.
Isishwankathelo, i-CMC inethemba elibanzi losetyenziso kunye nexabiso elibalulekileyo lesicelo kushishino lwezogquma. Ayiphuculi nje kuphela ukusebenza kunye nomgangatho weengubo kodwa ihlangabezana neemfuno zoluntu lwangoku zokhuseleko lokusingqongileyo kunye nophuhliso oluzinzileyo. Ngophuhliso oluqhubekayo loshishino lokugquma, i-CMC ngokungathandabuzekiyo iya kudlala indima ebalulekileyo kwimarike yexesha elizayo.
