Njengezinto ezisetyenzisiweyo zokwakha ezisetyenzisiweyo kwishishini lokwakha, udaka udlala indima ebalulekileyo yesakhiwo kunye nemisebenzi esebenzayo. Ulwelo lodaka yenye yeempawu ezibalulekileyo ezichaphazela intsebenzo yawo yokwakha. Ulwelo oluhle lunegalelo ekwenziweni kwemisebenzi yokwakha kunye nomgangatho wesakhiwo. Ukwenzela ukuphucula ulwalamano kunye nokusebenza kodaka, ii -overs ezahlukeneyo zihlala zisetyenziselwa uhlengahlengiso. Phakathi kwabo,hydroxypropyl methylcelculose (hpmc), njenge-polymer ye-polymer esetyenziswa ngamanzi asetyenziswayo, idlala indima ebalulekileyo kudaka. .
Iimpawu ezisisiseko ze-HPMC: i-HPMC yizinto ezinyibilikayo ze-polymer owenziwe kwi-molsulose yendalo eguqulweyo. Inesidenge esihle, ukugcinwa, ukugcinwa kwamanzi kunye nezinye iipropathi. Inganyibiliki emanzini, kodwa inokwenza isisombululo se-vicous emanzini, oko kuhlala kusetyenziswa ngokubanzi ngokwakhiwa, iingubo, amayeza kunye namanye amasimi. Xa isetyenziswa njenge-arting, i-HPMC inokuphucula ngokufanelekileyo ubulwele, ukugcinwa kwamanzi kunye nokusebenza kwamanzi kunye nokusebenza kodaka.
Indlela yempembelelo ye-HPMC kwi-Deard Felity:
Isiphumo sokuqaqamba: I-HPMC ngokwayo inefuthe elibalulekileyo lokuqina. Xa kuvela udaka, kunokonyusa i-viscogosity yodaka. Iziphumo zokubanzi ngenxa yeemolekyuli ze-HPMC zenza ubume benethiwekhi emanzini, ezifumana amanzi nokwandiswa, ukwandisa iSigaba samanzi. Le nkqubo ivumela ukungabikho kodaka ukuba luhlengahlengiswe. Xa umxholo we-HPMC elulalweni uphakame, ukuhamba kwamanzi okukhulu kwamanzi kuya kuthintelwa ukuya kwinqanaba elithile, ngoko ke ukuntywila kodaka kuya kubonisa utshintsho oluthile.
Ukuphucula ukugcinwa kwamanzi: i-HPMC inokwenza ifilimu ecekeceke kudaka ukunciphisa ukuvela kwamanzi kunye nokuphucula ukugcinwa kwamanzi kodaka. Udaka oluhle kakhulu lwamanzi lunokugcina ukubaluleka kwexesha elide, nto leyo ibalulekile ekufumanekeni kolwakhiwo ngexesha lokwakhiwa. Ukugcinwa kwamanzi aphezulu kunokuluthintela udaka ukuba luphume ngaphambi kwexesha kwaye kuphuculwe ixesha lokwakha kunye nokusebenza kakuhle kodaka.
Ukusasazeka: I-HPMC inokwenza isisombululo seColoidal emanzini, esinokuphucula ukusasazwa phakathi kwezinto ezingudaka. Ukungcola kodaka akuhambelani kuphela nenani lesamente, isanti kunye nokuxhuzulwa, kodwa kunye nokuhambelana nokusasazeka kwala macandelo. Ngokuhlengahlengisa isixa se-HPMC, amacandelo odaka angasasazeka ngakumbi, ngaloo ndlela ukuphucula ukwenziwa kobuqhophololo.
Iziphumo zokulungisa: I-HPMC inokukhuthaza ukusasazeka kwamasuntswana kudaka kunye nokuphucula uzinzo lwesakhiwo sayo. Ngokuphucula isiphumo segqwetha, i-HPMC inokugcina ulwalamano oluhle kakhulu lodaka ngexesha lokugcina ixesha elide kwaye kuthintele ukuncipha kolwelo ngenxa yokulibaziseka kwexesha.
Iziphumo zokuphucula iplastiki: Ukongezwa kwe-HPMC kunokuphucula iplasitiki yodaka, kwenza kube lula ukusebenza kwaye ube neplastiki engcono ngexesha lenkqubo yokwakha. Umzekelo, xa uqulunqe udonga, ulwelo olufanelekileyo kunye neplastiki lunokunciphisa ukuvela kwe-rocks kwaye kuphuculwe umgangatho wokubethelwa kwegesi.
Ukusetyenziswa okufanelekileyo kwe-HPMC kwinguqulelo yodaka:
Ulawulo lwe-Dosage: Umthamo we-HPMC uchaphazela ngokuthe ngqo ubulwele bodaka. Ngokubanzi, xa isixa esongeneyo se-HPMC siphakathi, ubunzi kunye nokugcinwa kwamanzi kudaka kunokuba kukuphuculwa kakhulu. Nangona kunjalo, i-HPMC egqithisileyo inokubangela ukuba umzobo wodaka ukuba lungaphezulu kakhulu, oluzinciphisa ubulwelo lwayo. Ke ngoko, isixa se-HPMC esongeziweyo kufuneka silawulwe ngokuchanekileyo ngokweemfuno ezithile kwizicelo.
I-Synegy kunye nezinye izinto ezenziwayo: Ukongeza kwi-HPMC, ezinye zihlala zongezwa ngodaka, ezinje ngeplastikhi, abahlali, njl. isondo. Umzekelo, abenzi be-superplastiki banokunciphisa inani lamanzi kudaka kwaye baphucule udaka lodaka, ngelixa i-HPMC inokuphucula ukugcinwa kwayo amanzi kunye nokusebenza kwayo ngelixa igcina i-viscogosity yodaka.
Uhlengahlengiso lweentlobo ezahlukeneyo zodaka: Iindidi ezahlukeneyo zodaka zineemfuno ezahlukeneyo zolwelo. Umzekelo, udaka lokuqhuba luneemfuno eziphezulu zobuqhophololo, ngelixa udaka lwe-masring luhlawula ingqalelo ngakumbi kububi bayo kunye nobungqingqwa bayo. Ngeli xesha le nkqubo, inani kunye nohlobo lwe-HPMC eyongeziweyo ekufuneka ilungiselelwe kwaye ilungiswe ngokweemfuno zomhlaba oqhelekileyo ukuqinisekisa ukuziqhelanisa nokulinganisa.
Njengesiqhelo esisetyenziswayo esisetyenziswayo,I-HPMCInokulungelelanisa ngokufanelekileyo udaka lodaka ngokutyibilika, ukugcinwa kwamanzi, ukusasazeka, ukugcwala, njl njl. Nangona kunjalo, umthamo we-HPMC kufuneka uhlengahlengiswe ngokuchanekileyo ngokweemeko ezithile zesicelo ukuphepha ukusetyenziswa ngokugqithisileyo okukhokelela ekunciphiseni ulwelo. Ngokuphuculwa okuqhubekayo kweemfuno zomsebenzi wodaka kumzi-mveliso wokwakha, isiphumo solawulo se-HPMC sinamathuba okusebenzisa isicelo kwixesha elizayo.
