I-Putty yinto ebalulekileyo yokwakha esetyenziselwa ukulinganisa udonga, kwaye ukusebenza kwayo kuchaphazela ngokuthe ngqo ukunamathela kwepeyinti kunye nomgangatho wokwakha. Ekuqulunqweni kwe-putty, izongezo ze-ether ze-cellulose zidlala indima ebalulekileyo.IHydroxypropyl Methylcellulose (HPMC), njengenye yezona zinto zisetyenziswa ngokuqhelekileyo i-cellulose ethers, inokuphucula ngokufanelekileyo i-viscosity, ukusebenza kokwakhiwa kunye nokuzinza kokugcinwa kwe-putty.
1. Iimpawu ezisisiseko zeHydroxypropyl Methylcellulose
I-HPMC yi-polymer enganyibilikiyo yamanzi e-non-ionic enokuqina okulungileyo, ukugcinwa kwamanzi, ukusabalalisa, i-emulsification kunye neepropati zokwenza ifilimu. I-viscosity yayo ichaphazeleka kwinqanaba lokutshintshwa, iqondo le-polymerization kunye neemeko zokunyibilika. Isisombululo samanzi se-AnxinCel®HPMC sibonisa iimpawu ze-pseudoplastic fluid, oko kukuthi, xa izinga lokucheba linyuka, i-viscosity yesisombululo iyancipha, eyona nto ibalulekileyo ekwakhiweni kwe-putty.
2. Impembelelo ye-HPMC kwi-putty viscosity
2.1 Ukuqina kwesiphumo
I-HPMC yenza isisombululo esiphezulu se-viscosity emva kokunyibilika emanzini. Ukuqina kwayo kubonakaliswa ikakhulu kule miba ilandelayo:
Ukuphucula i-thixotropy ye-putty: I-HPMC inokugcina i-putty kwi-viscosity ephezulu xa imile ukuphepha ukugoba, kunye nokunciphisa i-viscosity xa ikhuhla kwaye iphucula umsebenzi wokwakha.
Ukuphucula ukusebenza kwe-putty: Isixa esifanelekileyo se-HPMC sinokuphucula ukuthambisa kwe-putty, ukwenza ukukhuhla kube lula kunye nokunciphisa ukuxhathisa ukwakhiwa.
Ukuchaphazela amandla okugqibela e-putty: Umphumo wokuqina we-HPMC wenza into yokuzalisa kunye ne-cementitious kwi-putty ihlakazeke ngokulinganayo, ukuphepha ukwahlukana kunye nokuphucula ukusebenza lukhuni emva kokwakhiwa.
2.2 Impembelelo kwinkqubo yokufakwa kwamanzi
I-HPMC ineempawu ezigqwesileyo zokugcina amanzi, ezinokunciphisa ukuguquka kwamanzi ngokukhawuleza kumbane kwi-putty layer, ngaloo ndlela yongeza ixesha lokugalela iputty esekwe kwisamente kunye nokuphucula amandla kunye nokumelana nokuqhekeka kweputty. Nangona kunjalo, i-viscosity ephezulu kakhulu ye-HPMC iya kuchaphazela ukungena komoya kunye nesantya sokumisa se-putty, okukhokelela ekunciphiseni ukusebenza kakuhle kolwakhiwo. Ke ngoko, isixa se-HPMC kufuneka siqinisekise ukusebenza ngelixa siphepha iziphumo ezibi ngexesha lokuqina.
2.3 Ubudlelwane phakathi kobunzima bemolekyuli ye-HPMC kunye ne-viscosity ye-putty
Ukuphakama kobunzima bemolekyuli ye-HPMC, kokukhona i-viscosity yesisombululo sayo samanzi. Kwi-putty, ukusetyenziswa kwe-high-viscosity HPMC (efana nodidi olune-viscosity enkulu kune-100,000 mPa·s) inokuphucula ngokubonakalayo ugcino lwamanzi kunye neempawu ezichasayo ze-putty, kodwa kunokukhokelela ekunciphiseni kokusebenza. Ngoko ke, phantsi kweemfuno ezahlukeneyo zokwakha, i-HPMC ene-viscosity efanelekileyo kufuneka ikhethwe ukulinganisela ukugcinwa kwamanzi, ukusebenza kunye nokusebenza kokugqibela.
2.4 Impembelelo yedosi ye-HPMC kwi-putty viscosity
Ubungakanani be-AnxinCel®HPMC eyongeziweyo inefuthe elibalulekileyo kwi-viscosity ye-putty, kwaye i-dosage idla phakathi kwe-0.1% kunye ne-0.5%. Xa idosi ye-HPMC iphantsi, isiphumo sokutyeba kwi-putty silinganiselwe, kwaye ayinakukwazi ukuphucula ngokufanelekileyo ukusebenza kunye nokugcinwa kwamanzi. Xa idosi iphezulu kakhulu, i-viscosity ye-putty inkulu kakhulu, ukuxhathisa ukwakhiwa kuyanda, kwaye kunokuchaphazela isantya sokumisa se-putty. Ngoko ke, kuyimfuneko ukukhetha inani elifanelekileyo le-HPMC ngokwefomula ye-putty kunye nendawo yokwakha.
I-Hydroxypropyl methylcellulose idlala indima ekuqiniseni, ukugcinwa kwamanzi kunye nokuphucula ukusebenza kwi-putty. Ubunzima bemolekyuli, iqondo lokutshintshwa kunye nesixa esongezelelweyo seHPMCiya kuchaphazela i-viscosity ye-putty. Isixa esifanelekileyo se-HPMC sinokuphucula ukusebenza kunye nokuxhathisa kwamanzi kwi-putty, ngelixa ukongezwa okugqithisileyo kunokunyusa ubunzima bokwakha. Ngoko ke, kwisicelo sangempela se-putty, iimpawu ze-viscosity kunye neemfuno zokwakha ze-HPMC kufuneka ziqwalaselwe ngokubanzi, kwaye ifomula kufuneka ihlengahlengiswe ngokufanelekileyo ukuze kufumaneke ukusebenza kakuhle kokwakhiwa kunye nomgangatho wokugqibela.
