Ukuhlamba i-powder yimveliso eqhelekileyo yokucoca, ikakhulu isetyenziselwa ukuhlamba iimpahla. Kwifomula yomgubo wokuhlamba, izithako ezininzi ezahlukeneyo zibandakanyiwe, kwaye enye yeezongezo ezibalulekileyo yi-CMC, ebizwa ngokuba yiComboxymethyl sedium. I-CMC isetyenziswa ngokubanzi kwiimveliso zabathengi ezininzi njenge-gickener, i-sticker kunye nearhente yokumisa. Ngomgubo wokuhlamba, umsebenzi ophambili we-CMC kukuphucula isiphumo sokuhlamba i-powder, gcina ukufana komgubo, kwaye udlale indima ekugcinweni kwamanzi ngexesha lenkqubo yokuhlamba. Ukuqonda umxholo we-CMC ngokuhlamba i-powder ibaluleke kakhulu ekuqondeni intsebenzo kunye nokukhusela isisingqongileyo somgubo wokuhlamba.
1. Indima ye-CMC kwi-powder
I-CMC isebenza njengearhente yokumisa kunye ne-tickener ekuchitheni umgubo. Ngokukodwa, indima yayo ibandakanya le miba ilandelayo:
Ukuphucula isiphumo sokuhlamba: i-CMC inokuthintela ukungcola ukuba ihlawulwe kwilaphu, ngakumbi kuthintela amasuntswana amancinci kwaye anqunyanyiswe umhlaba oqokelele kumphezulu weempahla. Yenza ifilimu ekhuselayo ngexesha lokuhlamba ukunciphisa ukubanjwa kweengubo ezingcoliswe ngamabala kwakhona.
Zinzise ifomula yokuhlamba i-powder: i-CMC inokunceda ukukhusela ukwahlulwa kwezithako kwi-powder kwaye kuqinisekiswe ukusasazwa kwalo ngexesha lokugcina i-powder. Oku kubaluleke kakhulu ekugcineni ukusebenza kwexesha elide lokuhlamba umgubo wokuhlamba.
Ukugcinwa kwamanzi kunye nokuthamba: i-CMC inogcino oluhle lwamanzi kunye nokugcinwa kwamanzi, enokukunceda ukuhlamba i-powder kuchithiwe ngcono kwaye kugcinwe inani elithile lamanzi ngexesha lenkqubo yokucoca. Kwangelo xesha, inokwenza iimpahla zithambile kwaye zinyibilike emva kokuhlamba, kwaye akukho lula ukuba zome.
2. Uluhlu lomxholo we-CMC
Kwimveliso yemizi-mveliso, umxholo we-CMC ngokuhlamba i-powder ihlala ingaphezulu kakhulu. Ngokubanzi, umxholo we-CMC ngokuhlamba i-powder isuka kwi-2.5% kwi-2% **. Lo ngumyinge oqhelekileyo onokuthi uqinisekise ukuba i-CMC idlala indima yayo engaphezulu ngaphandle kokunyusa iindleko zokuveliswa komgubo wokuhlamba.
Umxholo othile uxhomekeke kwifomula yomgubo wokuhlamba kunye neemfuno zenkqubo zomenzi. Umzekelo, kwezinye iimpawu eziphezulu zokuhlamba umgubo wokuhlamba, umxholo we-CMC unokuba phezulu ukubonelela ngcono nokuhlaselwa kweziphumo. Kwiimpawu ezithile zokuphela okanye iimveliso ezixabiso eliphantsi, umxholo we-CMC unokuba sezantsi, okanye uthathe indawo zezinye ii-tickener eziphantsi okanye iiarhente zokumisa.
I-3. Izinto ezichaphazela umxholo we-CMC
Iindidi ezahlukeneyo zefomu yokuthintela iimpahla ezinqabileyo zinokufuna inani elahlukileyo le-CMC. Nazi izinto ezimbalwa ezichaphazela umxholo we-CMC:
Iindidi zokucoca impahla yokuhlamba iimpahla: Iindlela zokuchitha rhoqo nezihlanganisiweyo zendlela zinemixholo eyahlukileyo ye-CMC. Iicoci zokucoca impahla yokuhlamba iimpahla zihlala zifuna ubungakanani beethako ezisebenzayo, ngoko ke umxholo we-CMC unokwanda ngokufanelekileyo.
INJONGO YOKUGQIBELA YOKUGQIBELA Umxholo we-CMC ekuchitheni iindawo zokuhlamba iimpahla ngesandla usenokuba ngaphezulu kancinci ukunciphisa ukucaphukisa ulusu lwezandla.
Iimfuno zomsebenzi zokucoca iimpahla: kwezinye iindawo zokucoca iinyawo zeli fakrikhi ezizodwa okanye i-antibacteritery yokuhlambela, umxholo we-CMC unokuhlengahlengiswa ngokweemfuno ezithile.
Iimfuneko zokusiNgqongileyo: Ngokwanda kokuqonda kwendalo, abavelisi abaninzi abaphantsi sele beqalisile ukunciphisa ukusetyenziswa kwezithako ezithile zekhemikhali. Njengomntu onobuhlobo obunobuhlobo, i-CMC inokusetyenziswa ngakumbi kwiimveliso eziluhlaza. Nangona kunjalo, ukuba ezinye iindlela kwi-CMC ziphantsi ngexabiso kwaye zineziphumo ezifanayo, abavelisi abazinye banokukhetha ezinye iindlela.
I-4. Ukukhuseleka kwendalo kwi-CMC
I-CMC yindalo efudumeleyo, ihlala ikhutshwe kwi-seluplose yesityalo, kwaye inesifo esihle se-biodegradiance. Ngexesha lenkqubo yokuhlamba, i-CMC ayibangeli ungcoliseko olukhulu kwindalo esingqongileyo. Ke ngoko, njengenye yezithako ezikrwadayo zokuhlambela, i-CMC ithathwa njengenye yezongezwa ezinobuhlobo kwindalo.
Nangona i-CMC ngokwayo ayisebenzi, ezinye izithako kwi-willry yocopho, ezinjengee-pusfok, i-phosphates, inokuba nemiphumo emibi kwindalo esingqongileyo. Ke ngoko, nangona ukusetyenziswa kwe-CMC kunceda ukuphucula ukusebenza kwendalo kwendawo yokuhlambela, yinxalenye encinci yefomula iyonke yokuthintela iimpahla. Ingaba inokulingana ngokuyindalo ixhomekeke ekusebenziseni ezinye izithako.
Njengesithako esibalulekileyo kwi-roundry scordgent, i-sodium yebhokisi ye-sodiumthymethyl selulose (CMC) idlala indima yokutyibilika, ukumiswa nokukhusela iimpahla. Umxholo wayo uhlala uphakathi kwe-0.5% ne-2%, eya kulungiswa ngokwemigaqo yeendlela ezahlukeneyo zokuhlaselwa nokusetyenziswa. I-CMC ayinakuphucula nje isiphumo sokuhlamba, kodwa ikwabonelela ngokhuseleko oluthambileyo lweengubo, kwaye kwangaxeshanye linomgangatho othile wokukhusela isisi esingqongileyo. Xa ukhetha i-cullry yokuhlamba iimpahla, ukuqonda indima yezithako ezinje nge-CMC inokusinceda ukuba siqonde ngcono ukusebenza kwemveliso kwaye senze ukhetho olunobuhlobo kwindalo esingqongileyo.
