Ukongezaihydroxypropyl methylcellulose (HPMC)kwi-detergents yolwelo ifuna amanyathelo athile kunye nobuchule bokuqinisekisa ukuba inokunyibilika ngokupheleleyo kwaye idlale indima yokuqina, ukuzinzisa kunye nokuphucula i-rheology.
1. Iimpawu ezisisiseko kunye nemisebenzi ye-HPMC
Iimpawu ze-HPMC
HPMC a non-ionic cellulose etha kunye ukunyibilika elungileyo, ukutyeba kunye nokuzinza. Iyakwazi ukwenza isisombululo se-colloidal esicacileyo kwisistim samanzi kwaye sinamandla okuguquguquka kwiqondo lokushisa kunye ne-pH.
Indima kwizicoci zolwelo
Isiphumo sokuqina: Ukubonelela nge-viscosity efanelekileyo kwaye uphucule imvakalelo yezokucoca.
Ukuphuculwa kozinzo: Thintela i-stratification yesicoci okanye imvula.
Uhlengahlengiso lwe-Rheology: Nika izicoci ezingamalwelo ukuba zibe nolwelo olulungileyo kunye nokukwazi ukunqunyanyiswa.
Ukuphucula amava omsebenzisi: Ukuphucula ukuzinza kunye nokunamathela kwe-foam.
2. Amanyathelo asisiseko okongeza i-HPMC
Ukulungiselela
Ukukhetha: Khetha imodeli efanelekileyo ye-HPMC (efana nebakala le-viscosity, i-degree of substitution, njl.) ngokweemfuno zemveliso. Iimodeli eziqhelekileyo ziquka i-viscosity ephantsi kunye ne-viscosity ephezulu ye-HPMC yeziphumo ezahlukeneyo zokutyeba.
Ukuweyisha: Veyisha ngokuchanekileyo iHPMC efunekayo ngokweemfuno zefomula.
Ukusasaza kwangaphambili i-HPMC
Ukukhethwa kwemidiya: Ukusasaza kwangaphambili i-HPMC ngamanzi abandayo okanye enye imidiya enganyibilikiyo (efana ne-ethanol) ukuthintela ukubunjwa kwamaqhuma xa yongezwa ngokuthe ngqo.
Indlela yokongeza: Chitha kancinci i-HPMC emanzini abandayo avuselelweyo ukunqanda ukuhlangana.
Inkqubo yokuvuselela: Qhubeka uvuselela malunga nemizuzu eyi-10-15 de ukusabalalisa okufanayo.
Amanyathelo okuphelisa
Ukufudumeza kusebenze: Fudumeza ukusasazwa kwi-40-70 ℃ ukukhuthaza ukudumba kunye nokupheliswa kwe-HPMC. Kufuneka kuqatshelwe ukuba ubushushu bokupheliswa kwe-HPMC yeemodeli ezahlukeneyo zahluke kancinane.
Ukuvuselela kunye nokunyibilika: Ngelixa ufudumeza, qhubeka ushukumisa ngesantya esiphakathi de i-HPMC inyibilike ngokupheleleyo yenze ulwelo olucacileyo okanye olumhlophe olufana nobisi.
Ukuxuba kunye nolwelo lwesiseko sesicoci solwelo
Ukupholisa unyango: Pholisa iHPMCisisombululo kwiqondo lokushisa kwegumbi ukuphepha impembelelo yobushushu obugqithisileyo kwezinye izithako ezisebenzayo ze-detergent.
Ukongezwa ngokuthe ngcembe: Yongeza kancinane isisombululo se-HPMC kulwelo lwesiseko sesicoci solwelo ngelixa ushukumisa ukuqinisekisa ukusasazwa okufanayo.
Uhlengahlengiso lwe-Viscosity: Lungisa ubungakanani besisombululo se-HPMC ukufezekisa i-viscosity efunekayo.
3. Izilumkiso
Kuphephe ukungqubana
Xa ufaka i-HPMC, yifefe ngokucothayo kwaye ushukumise ngokulinganayo, kungenjalo kulula ukwenza i-agglomerate, ekhokelela ekunyibilikeni okungaphelelanga.
Ukusasazwa kwangaphambili linyathelo eliphambili, kwaye ukusetyenziswa kwamanzi abandayo okanye enye imidiya enganyibilikiyo inokuthintela ngokufanelekileyo i-agglomeration.
Indlela yokuvuselela
Sebenzisa ukuvuselela ngesantya esiphakathi ukunqanda amaqamza abangelwa kukushukuma okukhawulezileyo, okuya kuchaphazela inkangeleko yomgangatho wezicoci zolwelo.
Ukuba kuyenzeka, sebenzisa isixhobo sokucheba esiphakamileyo ukuphucula ukusebenza kakuhle kokusasazwa.
Ulawulo lobushushu
I-HPMC inovakalelo kubushushu, kwaye amaqondo obushushu aphezulu kakhulu okanye asezantsi kakhulu anokubangela ukonakala okungalunganga okanye ukulahleka komsebenzi. Ngoko ke, ukushisa kufuneka kulawulwe ngokungqongqo ngexesha lokuchithwa.
Ukuhambelana nezinye izithako
Jonga ukuhambelana kwe-HPMC kunye nezinye izithako kwi-seargent, ngakumbi imeko-bume yetyuwa ephezulu inokuchaphazela isiphumo sokujiya se-HPMC.
Kwiifomula zokucoca eziqulethe ii-asidi ezinamandla okanye ii-alkali ezinamandla, ukuzinza kwe-HPMC kufuneka kuqinisekiswe.
Ixesha lokupheliswa
Kuthatha ixesha elithile ukuba i-HPMC inyibilike ngokupheleleyo, kwaye kufuneka ishukunyiswe ngomonde ukuphepha ukungazinzi kwe-viscosity ngenxa yokuchithwa okungagqibekanga.
4. Iingxaki eziqhelekileyo kunye nezisombululo
Ubunzima bokuphelisa
Isizathu: I-HPMC inokuba yi-agglomerated okanye iqondo lobushushu lonyiso alifanelekanga.
Isisombululo: Lungiselela inyathelo langaphambi kokusasazwa kwaye ulawule ngokungqongqo inkqubo yokufudumeza kunye nokuvuselela.
I-Detergent stratification okanye imvula
Isizathu: Ukongezwa kweHPMC okungonelanga okanye ukupheliswa okungaphelelanga.
Isisombululo: Yandisa isixa se-HPMC ngokufanelekileyo kwaye uqinisekise ukuchithwa okupheleleyo.
I-viscosity ephezulu
Isizathu: I-HPMC eninzi kakhulu yongezwa okanye ixutywe ngokungalinganiyo.
Isixazululo: Nciphisa ngokufanelekileyo inani elongezelelweyo kwaye wandise ixesha lokuvuselela.
UkongezaHPMCkwizicoci zolwelo yinkqubo efuna ulawulo olusulungekileyo. Ukusuka ekukhetheni imodeli efanelekileyo ye-HPMC ukuya ekuphuculeni kunye namanyathelo okuxuba, inyathelo ngalinye linempembelelo ebalulekileyo ekusebenzeni kwemveliso yokugqibela. Ngokusebenza okuchanekileyo, ukujiya, ukuzinzisa kunye nemisebenzi yohlengahlengiso lwe-rheology ye-HPMC inokusetyenziswa ngokupheleleyo, ngaloo ndlela iphucula ukusebenza kunye nokhuphiswano lwentengiso lwezicoci zolwelo.
