IHydroxypropyl methylcellulose kunye ne-sodium carboxymethylcellulose zizinto ezimbini eziphuma kwiselulosi ezisetyenziswa kakhulu kumashishini ahlukeneyo.Zonke zineempawu ezizodwa kwaye zongezwa ngokuqhelekileyo ekutyeni, amayeza, izimonyo kunye nezinto zokwakha.Umbuzo osoloko ubuzwa ngabasebenzi beshishini kukuba ingaba i-hydroxypropyl methylcellulose kunye ne-sodium carboxymethylcellulose inokuxutywa.Impendulo kukuba ewe, zinokuxutywa kwaye iingenelo zolu kudibanisa zininzi.
IHydroxypropylmethylcellulose, ekwabizwa ngokuba yi-HPMC, yi-cellulose elungisiweyo eguqulwe ngokwekhemikhali ukuze iphucule iimpawu zayo.Isetyenziswa kakhulu njenge-thickener kunye ne-emulsifier ekutyeni, kwizinto zokuthambisa kunye namayeza.I-HPMC inyibilika ngokulula emanzini, ibonelela ngesisombululo esizinzileyo, esicacileyo.Ikwayaziwa ngokuba yi-viscosity ephezulu kunye neempawu ezibalaseleyo zokwenza ifilimu.
Kwelinye icala, i-sodium carboxymethylcellulose, ekwabizwa ngokuba yi-CMC, iphuma kwi-cellulose enyibilikayo emanzini esetyenziswa ngokubanzi njenge-thickener kunye nokuzinza ekutyeni nakumayeza.I-cellulose efunyenwe ngokusabela kwe-sodium chloroacetate kunye ne-cellulose.I-CMC nayo ayinayo ityhefu, iyabola kwaye ihambelana nokusingqongileyo.
I-HPMC kunye ne-CMC zineepropati ezihambelanayo ezibenza zibe yindibaniselwano efanelekileyo kwiintlobo ezahlukeneyo zezicelo.Zombini zinyibilika kakhulu emanzini kwaye zineempawu ezibalaseleyo zokujiya kunye ne-emulsifying.Ukongeza, zonke ziyahambelana noluhlu olubanzi lweekhemikhali kunye nezinye izithako, ezivumela ukuba zisetyenziswe kwiimveliso ezahlukeneyo.
Xa i-HPMC kunye ne-CMC zixutywe, isisombululo esisiphumo sineenzuzo ezininzi.Enye yeenzuzo eziphambili kukuba ibonelela ngolawulo oluhle kakhulu lwe-viscosity, okuthetha ukuba ingasetyenziswa njengento etyebisayo kwiimveliso ezininzi ezahlukeneyo, kubandakanya izinto zokuthambisa, iishampu kunye nezinye iimveliso zokhathalelo lomntu.Ukongeza, indibaniselwano ye-HPMC kunye ne-CMC ibonelela ngozinzo oluhle, iyenza ibe lolona khetho lubalaseleyo kwiimveliso ezifuna ubukhulu bexesha elide kunye nozinzo.
Enye inzuzo yokuxuba i-HPMC kunye ne-CMC kukuba inokuphucula ukusasazwa kwezithako.Xa ezi zimbini zisetyenziselwa kunye, zinokunceda ukusabalalisa izithako ngokulinganayo kwimveliso yonke, ukuphucula ukusebenza kwayo jikelele.Oku kuluncedo ngakumbi kumayeza apho ukusasazwa okufanayo kwesithako esisebenzayo kubaluleke kakhulu.
Zombini i-HPMC kunye ne-CMC zikwasetyenziswa kushishino lokwakha.Xa zisetyenziswa kunye, zibonelela ngokunamathela okugqwesileyo kunye ne-viscosity, ebaluleke kakhulu kwizicelo ezininzi zokwakha.Umdibaniso ubuye uzinze kakhulu, oku kuthetha ukuba ingasetyenziselwa kwiimveliso ezininzi ngaphandle kokukhathazeka ngokuhlukana.
I-Hydroxypropyl methylcellulose kunye ne-sodium carboxymethylcellulose zimbini ze-cellulose derivatives ezinokuxutywa kwaye zisetyenziswe kunye kuluhlu olubanzi lwezicelo.Izisombululo ezibangelwayo zinika indibaniselwano egqwesileyo yeempawu ezibandakanya ulawulo lwe-viscosity, uzinzo kunye nokuphuculwa kwe-dispersibility yesithako.Nokuba kukutya, kumayeza, kwizinto zokuthambisa okanye kwizinto zokwakha, indibaniselwano ye-HPMC kunye ne-CMC iqinisekile ukuba ibonelela ngeziphumo ezibalaseleyo.
