Ukuzinamathela ezilinganiselayo kuyindlela ethandwayo esetshenziselwa ukulinganisa kanye nezinjongo zokubopha ezimbonini ezahlukahlukene. Izakhiwo zayo ezihlukile zikwenza ilungele izinhlelo zokusebenza ezidinga indawo ebushelelezi, eyisicaba, njengokufika phansi, ukupenda nokufakwa kodonga.
Enye yezithako ezibalulekile ezakha adhesives ezizimisele yi-hydroxypropylllylyll methylcellulose (HPMC). I-HPMC ingukusulwa kweselula futhi isetshenziswa kabanzi ekuboleni, izinto zokwakha, izinamathiseli nakwezinye izinkambu.
Iqhaza eliphambili le-HPMC kuma-adhesives ezizimisele ukulawula i-viscosity kanye nokuvumelana kokunamathela. Izakhiwo ze-viscoelastic ze-HPMC zivumela ukunamathela ukugeleza kahle nangokulinganayo, kuqinisekisa indawo engaguquki futhi eyisicaba ngemuva kwesicelo.
I-HPMC ibuye ithuthukise izakhiwo ezibophayo zokunamathela okuzenzelayo, okwenza kube yisixazululo esifanelekile sokubopha ama-substrate ahlukahlukene. Lokhu kungenxa yamandla ahlukile we-HPMC ukwakha izibopho eziqinile ezinezindawo ezihlukile, kufaka phakathi ukhonkolo, ngokhuni kanye nensimbi.
Inani le-HPMC elalisetshenziswa ekunamatheksweni okuzimisele kakhulu lincike ezicini ezahlukahlukene, kufaka phakathi uhlobo lwe-substrate, ukuvumelana okudingayo kanye nendlela ethile yesicelo. Ngokuvamile, umthamo onconyiwe we-HPMC ngu-0,1% kuya ku-0.5% ngesisindo sokwakhiwa okunamathelayo.
Lapho ungeza i-HPMC ku-Adhesive Ezenzekayo, kufanele ixutshwe kahle nezinye izithako zokunamathela. Lokhu kuqinisekisa ngisho nokusatshalaliswa kwe-HPMC, okuholele ekunamatheleni okungaguquguquki futhi okufanayo.
I-HPMC idlala indima ebalulekile ekwakhekeni kwama-adhesives azimisele. Izakhiwo zayo ze-viscoelastic zenza kube yisixazululo esifanelekile sokuthola indawo ebushelelezi, eyisicaba ngenkathi futhi kuthuthukisa izakhiwo ezibophayo zokunamathela. Umthamo ofanele kanye nokusetshenziswa kwe-HPMC kubalulekile ekuqinisekiseni ukusebenza okufiselekayo kokunamathela okuzenzelayo.
