Ukusetyenziswa kwe-CMC kwiingubo
I-CMC,i-sodium carboxymethyl cellulose, ineendlela ezahlukeneyo zokusetyenziswa kushishino lwezogquma, ikakhulu isebenza njengesithambisi, isizinzisi, kunye noncedo lokwenza ifilimu, idlala indima ebalulekileyo ekuphuculeni ukusebenza kwezogquma. Apha ngezantsi kukho uhlalutyo oluneenkcukacha lwezicelo zeCMC kushishino lwezogquma:
1. Isiphumo sokuqina
I-CMC, i-compound yendalo ye-polymer enyibilikayo emanzini, inokunyusa ngempumelelo i-viscosity yeengubo kwaye ilawule iipropati zazo ze-rheological, yenze iingubo zibe lula kwaye kube lula ukuzisebenzisa. Ngokulawula ubungakanani be-CMC eyongeziweyo, umntu unokulungisa ngokuchanekileyo ukuhambelana kweepeyinti ze-latex, ngaloo ndlela ephucula ukusebenza kwazo, enciphisa ukuvuza, ephucula ukusebenza kakuhle kolwakhiwo, kwaye eqinisekisa ukuba i-coating ilingana.
2. Isiphumo sokuzinzisa
Iidayi kunye nezizalisi kwiingubo zihlala zihlala, nto leyo ekhokelela ekuhlukanisweni kweengubo. Ukongezwa kwe-CMC kunokuphucula kakhulu uzinzo lweengubo, kuthintele ukuhlala kweemibala kunye nezizalisi, kwaye kugcine iingubo zifana kwaye zihambelana ngexesha lokugcina nokusetyenziswa. Ingakumbi ngexesha lokugcina ixesha elide, isiphumo sokuzinza kwe-CMC sibaluleke kakhulu. Ulwakhiwo lwenethiwekhi olwenziwe yi-CMC lunokuthintela ngokufanelekileyo ukuhlala kweemibala kunye nezizalisi, lugcine ukusasazeka kunye nokufana kweengubo.
3. Isiphumo soNcedo lokuYila iiFilimu
I-CMC idlala indima encedisayo kwinkqubo yokwenza ifilimu yokugquma, yenza ukuba ukugquma okwenziweyo kube lukhuni kwaye kube bushelelezi emva kokomiswa. Oku akuphuculi nje kuphela umgangatho wembonakalo yokugquma, njengokunciphisa amabala ebrashi kunye nemiphumo yexolo loorenji, kodwa kwandisa ukumelana nokuguguleka kokugquma, ukumelana nokwaluphala, kunye nokumelana namanzi, ngaloo ndlela kwandisa ubomi benkonzo yokugquma.
4. Ukusebenza kokusingqongileyo
Ngenxa yokwanda okuqhubekayo kweemfuno zokhuseleko lokusingqongileyo, iingubo ezisekelwe emanzini ziye zaba yeyona nto iphambili kwimarike.I-CMC, njengesongezo sogqumathiso esinobuhlobo nokusingqongileyo, asinazo izinto eziyingozi kwaye siyahlangabezana nemigangatho yokhuseleko lokusingqongileyo yesizwe. Ukusetyenziswa kwe-CMC kwiingubo zogqumathiso akunakunciphisa kuphela umxholo we-VOCs (iikhompawundi ze-organic eziguquguqukayo) kodwa kukwaphucula ukusebenza kokusingqongileyo kweengubo zogqumathiso, ukuhlangabezana neemfuno zophuhliso oluzinzileyo loluntu lwanamhlanje.
5. Uluhlu olubanzi lwezicelo
I-CMC ayifanelekanga kuphela kwiipeyinti zelatex eziqhelekileyo kunye neengubo ezisekelwe emanzini, kodwa ikwafanelekile nakwiindawo ezikhethekileyo zokugquma ezifana neengubo zeemoto, iingubo zaselwandle, iingubo zodidi lokutya, kunye neengubo zonyango. Kule mimandla, i-CMC inokuphucula kakhulu ukuqina kunye nokumelana nokugqwala kweengubo, iqinisekisa ukhuseleko kunye nokukhuselwa kwendalo kweemveliso.
Ngamafutshane, i-CMC inamathuba amaninzi okusetyenziswa kunye nexabiso elikhulu lokusetyenziswa kwishishini leengubo. Ayiphuculi nje kuphela ukusebenza kunye nomgangatho weengubo kodwa ikwahlangabezana neemfuno zoluntu lwanamhlanje zokukhuselwa kwendalo kunye nophuhliso oluzinzileyo. Ngophuhliso oluqhubekayo lweshishini leengubo, i-CMC ngokungathandabuzekiyo iya kudlala indima ebaluleke ngakumbi kwimarike yexesha elizayo.
