I-cellulose ethers, njenge-methyl cellulose (MC) kunye ne-hydroxypropyl methyl cellulose (HPMC), isetyenziswa ngokubanzi kwiimveliso ezisekelwe kwi-samente ngenxa yokugcinwa kwamanzi okugqwesileyo, ukusebenza, kunye neempawu zokubambelela. Nangona kunjalo, ukusebenza kwe-cellulose ethers kwiimveliso zesamente kunokuchaphazeleka ngezinto ezahlukeneyo, kubandakanya uhlobo kunye nedosi ye-cellulose ether, uhlobo kunye nomthamo wesamente, iimeko zokunyanga, kunye neemeko zokusingqongileyo. Ngoko ke, kubalulekile ukulawula ngokufanelekileyo ukusebenza kwe-cellulose ethers kwiimveliso zesamente ukuqinisekisa umgangatho ohambelanayo kunye nokusebenza.

1. Ukukhethwa kweCellulose Etere Uhlobo kunye neDosage

Ukukhethwa kohlobo lwe-cellulose ether kunye ne-dosage kubalulekile ekulawuleni ukusebenza kwe-cellulose ethers kwiimveliso zesamente. I-ethers ye-cellulose eyahlukeneyo ineempawu ezahlukeneyo, kwaye ukhetho lohlobo olufanelekileyo lwe-cellulose ether luxhomekeke kwisicelo esithile kunye neemfuno zokusebenza. Umzekelo, i-HPMC idla ngokusetyenziswa kwiintambo zokuncamathelisa iithayile ngenxa yogcino lwamanzi olugqwesileyo kunye neempawu zokuncamathelisa, ngelixa i-MC iqhele ukusetyenziswa kwii-renders kunye nodaka ngenxa yokusebenza kwayo okugqwesileyo kunye neempawu zokugcina amanzi.

Idosi ye-cellulose ether nayo idlala indima ebalulekileyo ekulawuleni ukusebenza kwayo kwiimveliso zesamente. Idosi efanelekileyo ye-cellulose ether ixhomekeke kwizinto ezahlukeneyo, kubandakanywa uhlobo kunye nedosi yesamente, ukusebenza okufunekayo kunye nokugcinwa kwamanzi, kunye neemeko zokusingqongileyo. Ngokuqhelekileyo, i-dosage ye-cellulose ether isuka kwi-0.1% ukuya kwi-2% ngesisindo se-samente, kuxhomekeke kwisicelo esithile kunye neemfuno zokusebenza.

2. Ukuhambelana neSamente

Ukuhambelana kwe-cellulose ether kunye nesamente kubalulekile ekulawuleni ukusebenza kwayo kwiimveliso zesamente. Ukongezwa kwe-cellulose ether kwisamente kunokuchaphazela ixesha lokumisela, amandla, kunye nokusebenza kwesamente, kuxhomekeke kuhlobo kunye nomlinganiselo we-cellulose ether kunye nohlobo lwesamente. Ngoko ke, kubalulekile ukuqinisekisa ukuhambelana kwe-cellulose ether kunye nesamente ukuqinisekisa umgangatho ohambelanayo kunye nokusebenza.

Ukuhambelana kwe-cellulose ether kunye ne-samente kunokuvavanywa ngokuqhuba iimvavanyo zokuhambelana, ezifana novavanyo lweVicat, uvavanyo lwexesha lokuqala kunye nokugqibela, kunye novavanyo lwamandla oxinzelelo. Iziphumo zolu vavanyo zinokunika ulwazi oluxabisekileyo malunga nokusebenza kwe-cellulose ether kwimveliso yesamente kwaye ingasetyenziselwa ukulungelelanisa uhlobo kunye ne-dosage ye-cellulose ether.

3. Iimeko Zokunyanga

Iimeko zokuphilisa zeemveliso zesamente zinokuchaphazela kakhulu ukusebenza kwe-cellulose ethers. Iimeko zokunyanga, kubandakanywa ubushushu, ukufuma, kunye nexesha lokunyanga, kunokuchaphazela i-hydration yesamente kunye nokusebenza kwe-cellulose ethers. Ezona meko zokunyanga zixhomekeke kwisicelo esithile kunye neemfuno zokusebenza.

Umzekelo, kwii-adhesives zethayile, iimeko zokunyanga ezona zilungileyo zihlala kwindawo yobushushu begumbi kunye nokufuma okuphakathi kunye nexesha lokunyanga le-24 ukuya kwiiyure ezingama-48. Kunikezelo kunye nodaka, iimeko zokunyanga ezona zilungileyo zinokwahluka ngokuxhomekeke kwisicelo esithile, kodwa ngokuqhelekileyo kubandakanya amaqondo obushushu aphezulu kunye namaxesha amade okuphilisa.

4. Iimeko zokusingqongileyo

Iimeko zokusingqongileyo, ezifana neqondo lokushisa, ukufuma, kunye nokuvezwa kweekhemikhali okanye ukungcola, kunokuchaphazela ukusebenza kwe-cellulose ethers kwiimveliso zesamente. Ngokomzekelo, ukuvezwa kwamaqondo obushushu aphezulu okanye ukufuma okuphantsi kunokuchaphazela iipropati zokugcina amanzi eether ze-cellulose, ezikhokelela ekunciphiseni ukusebenza kunye nokubambelela. Ukubonakaliswa kweekhemikhali okanye ukungcola kunokuchaphazela nokusebenza kwe-cellulose ethers, okukhokelela ekunciphiseni amandla okanye ukuqina.

Ngoko ke, kubalulekile ukuqwalasela iimeko zokusingqongileyo ngexesha lokusetyenziswa kunye nokusetyenziswa kwe-cellulose ethers kwiimveliso zesamente. Ukugcinwa ngokufanelekileyo kunye nokuphathwa kwe-cellulose ethers kunokunceda ukugcina ukusebenza kwabo kunye nokuqinisekisa umgangatho ohambelanayo.

Ukuqukumbela, ukulawulwa okusebenzayo kokusebenza kwe-cellulose ethers kwiimveliso zesamente kufuna uqwalaselo ngononophelo lwemiba eyahlukeneyo, kubandakanywa uhlobo kunye nomthamo we-cellulose ether, ukuhambelana nesamente, iimeko zokunyanga, kunye neemeko zokusingqongileyo. Ngokulungisa le miba, kunokwenzeka ukufezekisa umgangatho ohambelanayo kunye nokusebenza kwe-cellulose ethers kwiimveliso zesamente, okukhokelela ekuphuculeni ukusebenza, ukugcinwa kwamanzi, kunye neempawu zokubambelela.
