I-Hydroxypropyl methylcellulose (HPMC)I-cellulose esetshenziswa kakhulu ye-cellulose esetshenziswayo ye-cellulose esetshenziswayo, esetshenziswa kabanzi ekwakheni, ezemithi, ukudla kanye nezimboni zamakhemikhali zansuku zonke. Ezintweni zokwakha, ikakhulukazi kuma-tile anamathela, amabhodlela odongeni, udaka olomile, njll.
1. Izici eziyisisekelo ze-HPMC
ICECCINCLELX ®PPMC iyi-cellubelose etholwa nge-solubity enhle yamanzi, ukunamathela kanye nemiphumela yokuqina. Kwakha i-colloid emanzini ngokusebenzisa amaqembu we-hydroxypropyl kanye ne-methyl ehlelweni lwayo lamangqamuzana, angathuthukisa ngempumelelo ukunamathela, i-Rhelogy kanye nokugcinwa kwamanzi okuqukethwe. Ezinhlosweni zokwakha, ukungezwa kwe-HPMC kungathuthukisa amandla e-bonding, kwandise isikhathi esivulekile, futhi kuthuthukise ukusakazeka kanye nokumelana kwamanzi. Ngakho-ke, inani le-HPMC lihlobene ngqo nokusebenza kwalezi zindawo, okuthinta umphumela wobumbano.
2. Umphumela we-HPMC DOSAGE emandleni eBonding
Amandla eBonding yinkomba ebalulekile yokuhlola umphumela wokwakha ama-adhesives wokwakha. Inani le-HPMC elingezwe ku-adhesive lingathinta kakhulu amandla okubopha. Ngakolunye uhlangothi, inani elifanele le-HPMC lingathuthukisa ubuhlobo namandla ezinto zokwenza amasimende. Lokhu kungenxa yokuthi i-HPMC ithuthukisa ukugcinwa kwamanzi ngodaka, ivumela usimende ukuthi aqhubeke kangcono ngamakhemikhali ngenqubo yokuqina phakathi kwenqubo yokuqina, ngaleyo ndlela enze ngcono umphumela wokugcina. Ngakolunye uhlangothi, lapho inani le-HPMC lincane kakhulu, ukugcinwa kwalo kwamanzi alwanele, okungadala ukuthi usimende ulahlekelwe ngamanzi ngaphambi kwesikhathi, okuthinta inqubo eqinile futhi kudala amandla aqine; Ngenkathi inani likhulu kakhulu, kungadala ukubanamathekuve kube nokubona kakhulu, okuthinta ukusebenza kokwakha futhi kubangele ukwehla kwamandla.
Ucwaningo lukhombisile ukuthi inani elifanelekile le-HPMC livame phakathi kuka-0.5% no-2%, elingathuthukisa amandla ngempumelelo amandla eBonding ngaphakathi kwaleli geli ngenkathi kusebenza. Kodwa-ke, inani elithile lidinga ukulungiswa ngokuya ngohlobo lwe-substrate kanye nemvelo ethile yesicelo.
3. Umphumela wethango le-HPMC ekusebenzeni kwezokwakha
Ukusebenza kokwakha kungenye yezinkomba ezibalulekile zokuhlola anama-adhesives, ikakhulukazi kufaka phakathi uketshezi, ukukhululeka kokwakha nokusebenza okuguqukayo. Inani le-HPMC linomphumela obalulekile kulezi zindawo. Njengoba inani le-HPMC lenyuka, i-viscosity yokunamathela futhi iyanda, ikhombisa ukunamathela okuqinile nesikhathi esivulekile esivule isikhathi eside. Yize isikhathi esivulelekile kwesinye isikhathi singathuthukisa ukuguquguquka kokwakhiwa, kungadala futhi indawo yokwakha ukuba ibambe emuva futhi ithinta umphumela wokubopha.
Ngezinhlobo ezahlukene ze-substrates, njengamathayili, amatshe, izindonga, njll. Isibonelo, ezimweni lapho isikhathi eside sokusebenza nokulungiswa kudingeka, okwandisa inani le-HPMC ngokufanele linganweba isikhathi esivulekile futhi sigweme ukomisa ngokushesha okukhulu, okuholele ekuboshweni okubuthakathaka kakhulu. Kodwa-ke, uma isikhathi esivulekile side kakhulu, kungadala ukushelela okungadingekile ngenkathi kwakhiwa futhi kuthinte ukunemba kokwakha.
4. Umphumela wethamo le-HPMC ekumelaneni kwamanzi kanye nokumelana nesimo sezulu
I-HPMC ayikwazi ukuthuthukisa amandla okubopha kanye nokwenza umsebenzi wokwakha kuphela, kepha futhi ithuthukisa ukumelana kwamanzi kanye nokumelana nesimo sezulu kokunamathelayo. I-HPMC ithuthukisa ukugcinwa kwamanzi kasimende, ukuze ukunamathela okususelwa kuthusi ngeke kulahlekelwe amanzi ngokushesha ngesikhathi senqubo enzima, ngaleyo ndlela kuthuthukise ukumelana kwamanzi kanye nokumelana nesimo sezulu. Lapho umthamo we-HPMC kufanelekile, ukumelana kwamanzi nempilo yenkonzo yezinto ezibonakalayo kungathuthukiswa kakhulu, ikakhulukazi ezindongeni zangaphandle nasezindaweni ezinomswakama zibalulekile.
Kodwa-ke, i-HPMC eyeqile ingahle iholele ekunciphiseni ngokweqile kokunamathela, kuthinte ukuqina kwesakhiwo sezinto zokwakha amasimende, futhi kunciphise ukumelana kwamanzi. Ngakho-ke, ukwenza kahle umthamo we-HPMC ukuze ulinganise i-hydration kanye nokumelana kwamanzi ngosimende kuyisihluthulelo sokuqinisekisa umphumela wokubopha.
I-5. Umphumela wethamo le-HPMC kwezinye izakhiwo ezibonakalayo
Ngaphezu kwamandla eBonding, ukusebenza kokwakha, ukumelana kwamanzi, njll., Umthamo we-HPMC uzothinta nezinye izakhiwo ezinamabala. Isibonelo, ngokwanda komthamo we-HPMC, ukuqina kokunamathela kungathuthukiswa ngoba i-HPMC ingavimba ukudonswa kabusha nokuqina kokunamathela futhi kugcinwe izakhiwo zomzimba ezifanayo. Ngaphezu kwalokho, umthamo weI-HPMCFuthi kuhlobene kakhulu nezinto ezifana nombala, izakhiwo ze-anti-slip, nesikhathi sokwelapha sokunamathela. Imithamo ehlukene ye-HPMC ingafinyelela ukusebenza okuhle kakhulu komzimba ngaphansi kwezidingo ezahlukahlukene zokwakha.
Njengesengezo esibalulekile sokwakha anama-adhesives, i-ComfinCHELXYPPPMC inomthelela omkhulu emphumeleni obondiwe. Umthamo wayo udinga ukulungisikala ngokuya ngezidingo ezithile zokwakha, izici ezisezingeni eliphansi kanye nezimo zemvelo. Inani elifanele le-HPMC lingathuthukisa ngempumelelo amandla okubopha, ukusebenza kokwakha, ukumelana kwamanzi kanye nokumelana nesimo sezulu, ngenkathi kugcinwa ukuqina okuhle komzimba. Kodwa-ke, i-HPMC eyeqile noma enganele noma enganele ingahle iholele ezakhiweni ezinamathelayo ezingazinzile futhi ithinta umphumela wokubopha. Ngakho-ke, kuzinhlelo zokusebenza ezisebenzayo, kuyadingeka ukuthola umthamo ofanele we-HPMC ngokusebenzisa izivivinyo kanye nezinguquko ukuze uzuze umphumela ofanele wokubopha.
