I-Hydroxypropyl methylcellulose (HPMC)iwukuphuma kwe-cellulose encibilikayo esetshenziswa kakhulu emanzini, esetshenziswa kabanzi ekwakhiweni, kwezemithi, ezimbonini zokudla nezimboni zamakhemikhali zansuku zonke. Ezakhiweni zokwakha, ikakhulukazi kuma-adhesives we-tile, ama-putty odongeni, ama-morts owomile, njll., i-HPMC, njengesengezo esibalulekile, ayithuthukisi nje kuphela ukusebenza kokwakhiwa, kodwa futhi inomthelela obalulekile kumphumela wokubopha.
1. Izakhiwo eziyisisekelo ze-HPMC
I-AnxinCel®HPMC iphuma ku-cellulose enokuncibilika okuhle kwamanzi, ukunamathela kanye nemiphumela yokujiya. Yakha i-colloid emanzini ngokusebenzisa i-hydroxypropyl kanye namaqembu e-methyl esakhiweni sawo samangqamuzana, angathuthukisa ngokuphumelelayo ukunamathela, i-rheology nokugcinwa kwamanzi kwezinto. Ekwakheni okunamathelayo, ukungezwa kwe-HPMC kungathuthukisa amandla okubopha, kunwebe isikhathi esivulekile, futhi kuthuthukise ukusabalala nokumelana namanzi. Ngakho-ke, inani le-HPMC lihlobene ngokuqondile nokusebenza kwalezi zakhiwo, okubuye kuthinte umphumela wokubopha.
2. Umthelela womthamo we-HPMC emandleni okubopha
Amandla okubopha ayinkomba eyinhloko yokuhlola umphumela wezinto ezinamathelayo zokwakha. Inani le-HPMC elingezwe ku-adhesive lingathinta kakhulu amandla okubopha. Ngakolunye uhlangothi, inani elifanele le-HPMC lingathuthukisa ukuhlangana namandla ezinto ezisekelwe kusimende. Lokhu kungenxa yokuthi i-HPMC ithuthukisa ukugcinwa kwamanzi kodaka, okuvumela usimende ukuthi usabele kangcono ngamakhemikhali ne-substrate surface ngesikhathi senqubo yokuqina, ngaleyo ndlela kuthuthukiswe umphumela wokugcina wokubopha. Ngakolunye uhlangothi, lapho inani le-HPMC lincane kakhulu, ukugcinwa kwayo kwamanzi akwanele, okungabangela ukuthi usimende ulahlekelwe amanzi ngaphambi kwesikhathi, kuthinte inqubo yokuqina futhi kubangele amandla okubopha angazinzile; kuyilapho inani likhulu kakhulu, lingase libangele ukuba i-adhesive ibe yi-viscous kakhulu, ithinte ukusebenza kokwakhiwa futhi ibangele nokuncipha kwamandla.
Ucwaningo luye lwabonisa ukuthi inani elifaneleka kakhulu le-HPMC livamise ukuba phakathi kuka-0.5% no-2%, elingathuthukisa ngempumelelo amandla okubopha ngaphakathi kwalolu bubanzi kuyilapho kuqinisekisa ezinye izici ezifana nokuguquguquka nokusebenza kahle. Kodwa-ke, inani elithile lidinga ukulungiswa ngokuya ngohlobo lwe-substrate kanye nendawo ethile yohlelo lokusebenza.
3. Umthelela womthamo we-HPMC ekusebenzeni kokwakhiwa
Ukusebenza kokwakha kungenye yezinkomba ezibalulekile zokuhlola izinto zokunamathela, ikakhulukazi ezihlanganisa uketshezi, ukwakhiwa kalula kanye nesikhathi sokusebenza esilungisekayo. Inani le-HPMC linomthelela omkhulu kulezi zakhiwo. Njengoba inani le-HPMC likhula, i-viscosity ye-adhesive nayo iyanda, ikhombisa ukunamathela okuqinile kanye nesikhathi eside sokuvula. Nakuba isikhathi eside esivulekile ngezinye izikhathi singathuthukisa ukuguquguquka kokwakhiwa, kungase futhi kubangele indawo yokwakha ibambelele futhi ithinte umphumela wokubopha.
Ezinhlotsheni ezihlukene zama-substrates, njengamathayela, amatshe, izindonga, njll., inani le-AnxinCel®HPMC lidinga ukuthuthukiswa. Isibonelo, ezimeni lapho isikhathi eside sokusebenza nokulungiswa kuyadingeka, ukukhulisa inani le-HPMC ngokufanelekile kunganweba isikhathi esivulekile futhi kugweme ukoma ngokushesha, okuholela ekubopheni okubuthakathaka. Kodwa-ke, uma isikhathi esivulekile siside kakhulu, singabangela ukushelela okungadingekile ngesikhathi sokwakha futhi kuthinte ukunemba kokwakhiwa.
4. Umphumela womthamo we-HPMC ekungangeni kwamanzi kanye nokumelana nesimo sezulu
I-HPMC ayikwazi nje ukuthuthukisa amandla okubopha nokusebenza kokwakhiwa, kodwa futhi ithuthukise ukumelana kwamanzi nokumelana nesimo sezulu se-adhesive. I-HPMC ithuthukisa ukugcinwa kwamanzi kukasimende, ukuze okunamathelayo okusekelwe kusimende kungalahlekelwa amanzi ngokushesha phakathi nenqubo yokuqina, ngaleyo ndlela kuthuthukise ukumelana kwawo kwamanzi kanye nokumelana nesimo sezulu. Uma umthamo we-HPMC ufanelekile, ukumelana kwamanzi nempilo yesevisi yezinto ezibonakalayo kungathuthukiswa kakhulu, ikakhulukazi ezindongeni zangaphandle nasezindaweni ezinomswakama, lapho ukumelana kwamanzi okunamathelayo kubalulekile.
Kodwa-ke, i-HPMC eyeqile ingase iholele ekuqineni ngokweqile kokunamathelayo, kuthinte ukuqina kwesakhiwo sezinto ezisekelwe kusimende, futhi kunciphise ukumelana kwayo namanzi. Ngakho-ke, ukwenza ngcono umthamo we-HPMC ukuze ulinganisele ukugeleza kwamanzi kanye nokumelana namanzi kukasimende kuyisihluthulelo sokuqinisekisa umphumela wokubopha.
5. Umthelela womthamo we-HPMC kwezinye izakhiwo zomzimba
Ngaphezu kwamandla okubopha, ukusebenza kokwakhiwa, ukumelana namanzi, njll., umthamo we-HPMC uzophinde uthinte ezinye izakhiwo ezibonakalayo ze-adhesive. Isibonelo, ngokwanda komthamo we-HPMC, ukuzinza kwe-adhesive kungase kuthuthukiswe ngoba i-HPMC ingavimbela ukubola kanye nokuhlelwa kwe-stratification ku-adhesive futhi igcine izakhiwo ezibonakalayo ezifanayo. Ngaphezu kwalokho, umthamo weI-HPMCfuthi ihlobene eduze nezici ezifana nombala, izakhiwo zokulwa nokushelela, kanye nesikhathi sokuphulukisa sokunamathela. Imithamo ehlukene ye-HPMC ingafinyelela ukusebenza komzimba okuhle kakhulu ngaphansi kwezidingo ezahlukahlukene zokwakha.
Njengesengezo esibalulekile sokwakha izinto ezinamathelayo, i-AnxinCel®HPMC inomthelela obalulekile kumphumela wokubopha. Umthamo wayo udinga ukuthuthukiswa ngokuya ngezidingo ezithile zokwakha, izici ze-substrate nezimo zemvelo. Inani elifanele le-HPMC lingathuthukisa ngempumelelo amandla okubopha, ukusebenza kokwakhiwa, ukumelana namanzi kanye nokumelana nesimo sezulu, kuyilapho igcina ukuzinza okuhle ngokomzimba. Kodwa-ke, i-HPMC eyeqile noma enganele ingase iholele ezintweni zokunamathela ezingazinzile futhi ithinte umphumela wokubopha. Ngakho-ke, ekusetshenzisweni okungokoqobo, kuyadingeka ukunquma umthamo ophelele we-HPMC ngokuhlolwa nokulungiswa ukuze kuzuzwe umphumela ofanele wokubopha.
