Njengoko ishishini lokwakha liqhubeka lihlawula ingqwalasela engakumbi ekukhuselweni kwendalo kunye nophuhliso oluzinzileyo, ukukhuselwa kokusingqongileyo kwezinto zokwakha kuye kwaba yingqwalasela yophando. Udaka luyinto eqhelekileyo ekwakhiweni, kwaye ukuphuculwa komsebenzi wayo kunye neemfuno zokukhuselwa kwendalo zifumana ingqalelo ngakumbi nangakumbi.IHydroxypropyl methylcellulose (HPMC), njengesongezo sokwakha esisetyenziswa ngokuqhelekileyo, asikwazi nje ukuphucula ukusebenza kokwakhiwa kodaka, kodwa nokuphucula ukusebenza kokusingqongileyo kodaka ukuya kwinqanaba elithile.
1. Iimpawu ezisisiseko ze-HPMC
I-HPMC yikhompawundi yepolymer enyibilikayo emanzini eguqulwe ngokwekhemikhali ukusuka kwimicu yezityalo zendalo (ezifana nentlaka yeplanga okanye umqhaphu). Inokuqina okugqwesileyo, ukwenza ifilimu, ukugcinwa kwamanzi, i-gelling kunye nezinye iipropathi. Ngenxa yokuzinza kwayo okulungileyo, i-non-toxic, i-odorless kunye ne-degradable, i-AnxinCel®HPMC isetyenziswa ngokubanzi kwintsimi yokwakha, ngakumbi kumdaka. Njengezinto eziluhlaza kunye nokusingqongileyo, i-HPMC inefuthe elibalulekileyo ekusebenzeni kokusingqongileyo kodaka.
2. Ukuphuculwa komsebenzi wokwakhiwa kodaka yi-HPMC
Udaka olunobume bendalo alufunwa kuphela ukuhlangabezana namandla kunye nokuqina kwesiseko, kodwa lunomsebenzi omhle wokwakha. Ukongezwa kwe-HPMC kunokuphucula kakhulu ukusebenza kodaka, ngokukodwa ngolu hlobo lulandelayo:
Ukugcinwa kwamanzi: I-HPMC inokunyusa ukugcinwa kwamanzi kwi-mortar kwaye ithintele ukuphuphuma kwamanzi kwangaphambi kwexesha, ngaloo ndlela inciphisa iingxaki ezifana neentanda kunye ne-voids ezibangelwa ukulahleka kwamanzi ngokukhawuleza. Udaka olunokugcinwa kakuhle kwamanzi luvelisa inkunkuma encinci ngexesha lenkqubo yokuqina, ngaloo ndlela inciphisa ukuveliswa kwenkunkuma yokwakha kunye neziphumo ezingcono zokukhuselwa kokusingqongileyo.
I-Fluidity: I-HPMC iphucula ukuguquguquka kodaka, okwenza inkqubo yokwakha ibe lula. Ayiphuculi kuphela ukusebenza kakuhle, kodwa inciphisa inkunkuma kwimisebenzi eyenziwa ngesandla. Ngokunciphisa inkunkuma yezinto eziphathekayo, ukusetyenziswa kobutyebi kuncitshisiwe, okuhambelana nombono wokwakha okuluhlaza.
Yandisa ixesha lokuvula: I-HPMC inokwandisa ngokufanelekileyo ixesha lokuvula udaka, ukunciphisa inkunkuma engadingekile yodaka ngexesha lenkqubo yokwakha, ukuphepha ukusetyenziswa ngokugqithiseleyo kwezinye izinto zokwakha, kwaye ngaloo ndlela ukunciphisa umthwalo kwindalo.
3. Impembelelo ye-HPMC kumandla kunye nokuqina kodaka
Amandla kunye nokuqina kodaka kuhambelana ngokuthe ngqo nokhuseleko kunye nobomi benkonzo yesakhiwo. I-HPMC inokuphucula iipropati zoomatshini kunye nokuqina kodaka kwaye ichaphazele ngokungangqalanga ukusebenza kokusingqongileyo:
Ukuphucula amandla okuxinzelela kunye nokudibanisa amandla omdaka: Ukongezwa kwe-HPMC kunokuphucula amandla okuxinzelela kunye nokudibanisa amandla omdaka, ukunciphisa imfuno yokulungiswa kunye nokutshintshwa ngenxa yeengxaki ezisemgangathweni kwizinto zokwakha ngexesha lokusetyenziswa kwesakhiwo. Ukunciphisa ukulungiswa nokutshintshwa kuthetha inkcitho encinci yemithombo kwaye kuluncedo kwindalo esingqongileyo.
Ukuphucula ukunyanzeliswa kunye nokumelana neqabaka yodaka: Emva kokongeza i-HPMC kumdaka, ukunyanzeliswa kwayo kunye nokumelana neqabaka kuyaphuculwa. Oku akuphuculi kuphela ukuqina kodaka, kodwa kunciphisa umonakalo obangelwa yimeko enzima okanye ukuguga kwezinto. Ukusetyenziswa kobutyebi. Udaka olunokuqina okungcono lunciphisa ukusetyenziswa kwemithombo yendalo, ngaloo ndlela kunciphisa umthwalo wokusingqongileyo.
4. Impembelelo ye-HPMC kubungane bendalo kudaka
Ngaphantsi kweemfuno zezixhobo zokwakha ezihambelana nokusingqongileyo, udaka lusetyenziswa ngokuqhelekileyo. Ukukhuselwa kwayo kokusingqongileyo kubonakaliswa ikakhulu kule miba ilandelayo:
Ukunciphisa ukukhutshwa kwezinto ezinobungozi: I-AnxinCel®HPMC iguqulwe ngokwekhemikhali kwimicu yendalo yezityalo kwaye ayinayo ityhefu kwaye ayinabungozi. Ukusebenzisa i-HPMC kudaka ukutshintsha ezinye izongezo zemveli kunokunciphisa ukukhutshwa kwezinto ezinobungozi, ezifana ne-volatile organic compounds (VOCs) kunye nezinye iikhemikhali eziyingozi. Oku akuncedi nje ukuphucula umgangatho womoya wangaphakathi, kodwa kunciphisa ungcoliseko lokusingqongileyo.
Khuthaza uphuhliso oluzinzileyo: I-HPMC sisixhobo esivuselelekayo esivela kwimicu yezityalo zendalo kwaye inomthwalo omncinci wokusingqongileyo kuneemveliso zepetrochemical. Kwimeko yeshishini lokwakha elikhuthaza ukukhuselwa kokusingqongileyo okuluhlaza, ukusetyenziswa kwe-HPMC kunokukhuthaza uphuhliso oluzinzileyo lwezixhobo zokwakha kwaye luhambelana nesikhokelo solondolozo lwezixhobo kunye nophuhliso olungenabungozi kokusingqongileyo.
Nciphisa inkunkuma yokwakha: Ngenxa yokuba i-HPMC iphucula umsebenzi wokwakha udaka, inciphisa inkunkuma yezinto ngexesha lokwakha. Ukongeza, ukomelela okuphuculweyo kodaka kukwathetha ukuba isakhiwo asiyi kuvelisa inkunkuma eninzi kakhulu ngexesha lokusetyenziswa. Ukunciphisa ukuveliswa kwenkunkuma yokwakha kunceda ukunciphisa ukukhutshwa kwenkunkuma yokwakha.
5. UVavanyo lweMpembelelo yokuSingqongileyo ye-HPMC
NangonaHPMCinokusebenza kakuhle kokusingqongileyo kudaka, inkqubo yayo yokuvelisa isenempembelelo ethile yokusingqongileyo. Ukuveliswa kwe-HPMC kufuna ukuguqulwa kwemicu yezityalo zendalo ngokusabela kweekhemikhali. Le nkqubo inokubandakanya ukusetyenziswa kwamandla athile kunye nokukhutshwa kwerhasi eyinkunkuma. Ngoko ke, xa usebenzisa i-HPMC, kuyimfuneko ukuvavanya ngokubanzi ukukhuselwa kokusingqongileyo kwenkqubo yayo yokuvelisa kunye nokuthatha amanyathelo ahambelanayo ukunciphisa impembelelo yayo yokusingqongileyo. Uphando lwexesha elizayo lunokugxila kuphuhliso lobuchwepheshe bemveliso ye-HPMC ehambelana nokusingqongileyo kunye nokuphononongwa kwezinye iindlela eziluhlaza kwi-HPMC ngodaka.
Njengesongezo sokwakha esiluhlaza kunye nokusingqongileyo, i-AnxinCel®HPMC inefuthe elibalulekileyo ekusebenzeni kokusingqongileyo kodaka. Akunakuphucula kuphela ukusebenza kokwakhiwa kodaka, ukwandisa amandla kunye nokuqina kwayo, kodwa ukunciphisa ukukhutshwa kwezinto ezinobungozi, ukukhuthaza uphuhliso oluzinzileyo kunye nokunciphisa ukukhutshwa kwenkunkuma yokwakha. Nangona kunjalo, inkqubo yemveliso ye-HPMC iseneempembelelo ezithile zokusingqongileyo, ngoko ke kuyimfuneko ukuqhubela phambili nokwandisa inkqubo yokuvelisa kunye nokukhuthaza ukusetyenziswa kobugcisa bemveliso eluhlaza. Kwixesha elizayo, kunye nokuqhubela phambili kobuchwephesha bokukhusela indalo, i-HPMC iya kusetyenziswa ngokubanzi kwizinto zokwakha, ukwenza igalelo elikhulu ekufezekiseni izakhiwo eziluhlaza kunye nezakhiwo ezihambelana nokusingqongileyo.
