IHydroxypropyl methylcellulose (HPMC)yinto esetyenziswa ngokuqhelekileyo i-cellulose e-soluble derivative yamanzi, esetyenziswa ngokubanzi kulwakhiwo, amayeza, ukutya kunye namashishini ekhemikhali yemihla ngemihla. Kwizinto zokwakha, ngokukodwa kwi-adhesives tile, i-putty eludongeni, udaka olomileyo, njl., i-HPMC, njengesongezo esibalulekileyo, ayiphuculi nje kuphela umsebenzi wokwakha, kodwa inempembelelo ebalulekileyo kwimpembelelo yokubambisana.
1. Iimpawu ezisisiseko ze-HPMC
I-AnxinCel®HPMC yi-cellulose derivative ene-solubility efanelekileyo yamanzi, i-adhesion kunye nemiphumo yokuqina. Yenza i-colloid emanzini ngokusebenzisa i-hydroxypropyl kunye namaqela e-methyl kwisakhiwo sayo se-molecular, enokuphucula ngokufanelekileyo i-adhesion, i-rheology kunye nokugcinwa kwamanzi kwezinto. Ekwakhiweni kwe-adhesives, ukongezwa kwe-HPMC kunokuphucula amandla okudibanisa, ukwandisa ixesha elivulekileyo, kunye nokuphucula ukusasazeka kunye nokuxhatshazwa kwamanzi. Ngoko ke, inani le-HPMC lihambelana ngqo nokusebenza kwezi zakhiwo, ezichaphazela umphumo wokudibanisa.
2. Impembelelo yedosi ye-HPMC kumandla okudibanisa
Amandla okubambisana luphawu oluphambili lokuvavanya umphumo wokwakhiwa kwe-adhesives. Isixa se-HPMC esifakwe kwi-adhesive sinokuchaphazela kakhulu amandla okudibanisa. Kwelinye icala, isixa esifanelekileyo se-HPMC sinokuphucula ukudityaniswa kunye nokomelela kwemathiriyeli esekwe kwisamente. Oku kungenxa yokuba i-HPMC iphucula ukugcinwa kwamanzi kwidaka, ivumela i-samente ukuba iphendule kangcono ngamachiza kunye ne-substrate surface ngexesha lenkqubo yokuqina, ngaloo ndlela iphucula umphumo wokugqibela wokubopha. Ngakolunye uhlangothi, xa isixa se-HPMC sincinci kakhulu, ukugcinwa kwamanzi akwanele, okunokubangela ukuba i-samente ilahlekelwe ngamanzi ngaphambi kwexesha, ichaphazela inkqubo yokuqina kwaye ibangele amandla okudibanisa okungazinzanga; ngelixa xa isixa sikhulu kakhulu, kunokubangela ukuba i-adhesive ibe yi-viscous kakhulu, echaphazela umsebenzi wokwakha kwaye ibangele ukuhla kwamandla.
Uphononongo lubonise ukuba eyona mali ifanelekileyo ye-HPMC idla ngokuba phakathi kwe-0.5% kunye ne-2%, enokuphucula ngokufanelekileyo amandla okudibanisa phakathi kolu luhlu ngelixa iqinisekisa ezinye iipropati ezifana ne-fluidity kunye nokusebenza. Nangona kunjalo, inani elithile lifuna ukulungiswa ngokohlobo lwe-substrate kunye nemeko ethile yesicelo.
3. Ifuthe ledosi ye-HPMC ekusebenzeni kolwakhiwo
Ukusebenza kolwakhiwo sesinye sezibonakaliso ezibalulekileyo zokuvavanya i-adhesives, ngokukodwa kubandakanywa ukumanzi, ukukhululeka kokwakhiwa kunye nexesha lokusebenza oluhlengahlengiswayo. Isixa se-HPMC sinesiphumo esibalulekileyo kwezi zakhiwo. Njengoko inani le-HPMC linyuka, i-viscosity ye-adhesive iyanda, ibonisa ukunamathela okunamandla kunye nexesha elide lokuvula. Nangona ixesha elide elivulekileyo ngamanye amaxesha linokuphucula ukuguquguquka kolwakhiwo, kunokubangela ukuba umgangatho wokwakha unamathele kwaye uchaphazele umphumo wokudibanisa.
Kwiintlobo ezahlukeneyo ze-substrates, ezifana neetayile, amatye, iindonga, njl., inani le-AnxinCel®HPMC kufuneka liphuculwe. Ngokomzekelo, kwiimeko apho ixesha elide lokusebenza kunye nohlengahlengiso lufunekayo, ukwandisa inani le-HPMC ngokufanelekileyo kunokwandisa ixesha elivulekileyo kwaye ugweme ukomisa ngokukhawuleza, okubangela ukudibanisa okubuthathaka. Nangona kunjalo, ukuba ixesha elivulekileyo lide kakhulu, kunokubangela ukutyibilika okungafunekiyo ngexesha lokwakha kwaye kuchaphazele ukuchaneka kolwakhiwo.
4. Isiphumo somthamo we-HPMC ekuxhathiseni kwamanzi kunye nokumelana nemozulu
I-HPMC ayinakuphucula kuphela amandla okudibanisa kunye nokusebenza kokwakhiwa, kodwa nokuphucula ukuxhathisa kwamanzi kunye nokumelana nemozulu ye-adhesive. I-HPMC iphucula ukugcinwa kwamanzi kwi-samente, ukwenzela ukuba i-adhesive-based adhesive ayisayi kulahlekelwa ngamanzi ngokukhawuleza ngexesha lenkqubo yokuqina, ngaloo ndlela iphucula ukuxhathisa kwamanzi kunye nokumelana nemozulu. Xa i-dosage ye-HPMC ifanelekile, ukuxhathisa kwamanzi kunye nobomi benkonzo yezinto eziphathekayo kunokuphuculwa kakhulu, ngakumbi kwiindonga zangaphandle kunye neendawo ezifumileyo, apho ukuxhathisa kwamanzi okunamathela kubalulekile.
Nangona kunjalo, i-HPMC egqithisileyo inokukhokelela ekugqityweni okugqithisileyo kwe-adhesive, kuchaphazela ukuzinza kwesakhiwo sezinto ezisekelwe kwisamente, kunye nokunciphisa ukuxhathisa kwamanzi. Ngoko ke, ukulungelelanisa idosi ye-HPMC ukulungelelanisa i-hydration kunye nokuxhatshazwa kwamanzi kwi-samente ngundoqo ekuqinisekiseni umphumo wokubambisana.
5. Impembelelo yedosi ye-HPMC kwezinye iipropati zomzimba
Ukongeza kumandla okudibanisa, ukusebenza kokwakhiwa, ukuchasana kwamanzi, njl., i-dosage ye-HPMC iya kuchaphazela nezinye iipropati ezibonakalayo ze-adhesive. Ngokomzekelo, ngokunyuka kwedosi ye-HPMC, ukuzinza kwe-adhesive kunokuphuculwa kuba i-HPMC inokuthintela i-sedimentation kunye ne-stratification kwi-adhesive kwaye igcine iipropati ezibonakalayo ezifanayo. Ukongeza, umthamo weHPMCikwanxulumene ngokusondeleyo nezinto ezifana nombala, iipropathi ezichasene nokutyibilika, kunye nexesha lokunyanga lokuncamathelisa. Iidosi ezahlukeneyo ze-HPMC zinokufikelela okona kusebenza kakuhle ngokwasemzimbeni phantsi kweemfuno ezahlukeneyo zokwakha.
Njengesongezo esibalulekileyo sokwakha i-adhesives, i-AnxinCel®HPMC inefuthe elibalulekileyo kwimpembelelo yokudibanisa. Umthamo wayo kufuneka uphuculwe ngokweemfuno ezithile zokwakha, iimpawu ze-substrate kunye neemeko zokusingqongileyo. Imali efanelekileyo ye-HPMC inokuphucula ngokufanelekileyo amandla okudibanisa, ukusebenza kokwakhiwa, ukuxhathisa kwamanzi kunye nokumelana nemozulu, ngelixa ugcina uzinzo oluhle lomzimba. Nangona kunjalo, i-HPMC eninzi okanye engonelanga inokukhokelela kwiipropati zokunamathela ezingazinzanga kwaye ichaphazele umphumo wokudibanisa. Ke ngoko, kwizicelo ezisebenzayo, kuyafuneka ukugqiba ngedosi ye-HPMC ngovavanyo kunye nohlengahlengiso ukufezekisa isiphumo esifanelekileyo sokuhlangana.
