1. I-Hydroxypropyl methylcellulose (HPMC)Ingabe i-ether ye-cellulose engekho e-Ionic eyenziwe kusuka ku-Natural Cotton Fiber noma i-Soni Pulp ngochungechunge lwezinqubo zokucubungula amakhemikhali ezinjenge-alkalization, ukusheshisa, nokucwilisa. Ngokusho kokubonakala kwayo, i-HPMC ingahlukaniswa ibe i-viscosity ephezulu, ukubukeka okuphakathi nendawo, kanye nemikhiqizo ephansi ye-viscosity. Phakathi kwazo, i-viscosity ephansi i-HPMC esetshenziswa kabanzi emikhakheni eminingi ngenxa ye-soubity yayo enhle kakhulu, impahla eyakha ifilimu, ukuqina kokuqina, kanye nokuqina okuhlakazeka.
2. Izici eziyisisekelo ze-viscosity ephansi HPMC
I-Solubinity yamanzi: I-Viscosity ephansi i-HPMC ingena kalula emanzini abandayo futhi ingakha isixazululo esibonakalayo noma esibonakalayo, kepha iyakhohlisa emanzini ashisayo kanye nama-solvents amaningi we-organic.
I-Viscosity ephansi: Uma kuqhathaniswa ne-viscosity ephakathi nelephezulu ye-HPMC ephakathi nendawo ephakeme, isixazululo saso sine-viscosity ephansi, imvamisa ngo-5-100mpa · ikhambi elingamanzi, 25 ° C).
Ukuqina: Kunokuqina okuhle kwamakhemikhali, kubekezelela kakhulu ama-acid nase-alkali, futhi kungagcina ukusebenza okuzinzile ebangeni elibanzi le-PH.
Impahla eyakha ifilimu: Ingakha ifilimu efanayo ebusweni bezigatshana ezihlukile, ezinezakhiwo ezinhle zokubambelela kanye nokunamathelisa.
Ukugcotshwa: Kungasetshenziswa njengesithambisi sokunciphisa ukungqubuzana futhi kuthuthukise ukusebenza kwezinto.
Umsebenzi ongaphezulu: Ine-emulsation kanye namakhono okusabalalisa futhi angasetshenziswa ezinhlelweni zokuqiniswa kokukhulisa.
3. Izinkambu zohlelo lokusebenza ze-HPMC ephansi
Izinto zokwakha
Udaka noPutty: Udaka ngodaka olomile, udaka oluzimele, i-visuosting yodaka, i-hpmc ephansi ye-HPMC ingathuthukisa ngempumelelo ukusebenza kokwakha, ithuthukise ukugcinwa kwamanzi, futhi ivikele ukuqhekeka kwamanzi nosizi.
I-Tile Adhesive: Isetshenziswa njengesikhulu kanye ne-tinder ukwenza ngcono ukusebenziseka kokwakha namandla okubopha.
Imidwebo kanye nopende: Njengomkhuhlane kanye nokukhulisa ukumiswa, kwenza umfaniswano wokuhlanganisa, kuvimbela ukuqunjelwa kwe-pigment, futhi kuthuthukisa ukuxubha kanye nokulinganisa izakhiwo.
Umuthi nokudla
Ama-Exercients Pharmaceutical Exessients: I-HPMC ephansi ye-HPMC ingasetshenziswa kuma-tablet coatings, ama-ejenti wokukhipha okugciniwe, ukumiswa kanye nama-capsule filler emkhakheni wezemithi ukuze uzinze, ahlukanise futhi akhulule kancane.
Izithasiselo zokudla: Kusetshenziswe njengabakhulu, ama-emulsifiers, abakhuthele ekusebenzeni kokudla, njengokuthuthukisa ukunambitheka nokuthungwa ezindaweni ezibhakiwe, imikhiqizo yobisi namajusi.
Izimonyo nemikhiqizo yokunakekelwa komuntu siqu
Emikhiqizweni yokunakekelwa kwesikhumba, abahlanza ubuso, izimo, ama-gels neminye imikhiqizo, i-HPMC ingasetshenziswa njengomuntu omkhulu kanye nomswakama ukwenza lula ukuthungwa komkhiqizo, kwenze kube lula ukulusebenzisa kanye nokuthuthukisa induduzo yesikhumba.
Ubuciko kanye nobumbano
Embonini ye-Ceramic, i-HPMC ingasetshenziswa njenge-lubricant kanye nokubumba usizo lokuthuthukisa uketshezi lwedaka futhi luthuthukise amandla omzimba.
Embonini yamaphepha ephakethe, ingasetshenziselwa ukuhambisana kwamaphepha ukuthuthukisa ubushelelezi obukhona nokuguquguquka kwephepha.
Ukuvikelwa Kwezolimo Nezemvelo
I-viscosity ephansi i-HPMC ingasetshenziswa ekumisweni kokubulala izinambuzane ukuze uthuthukise ukuqina kwezidakamizwa futhi unwebe isikhathi sokukhishwa.
Ezintweni ezinobungane bemvelo, ezinjengezengezo zokwelashwa kwamanzi, ama-sustpressants athuli, njll., Kungathuthukisa ukuguquguquka kokusakaza futhi kuthuthukise umphumela wokusetshenziswa.
4. Sebenzisa kanye nokugcinwa kwe-viscosity ephansi HPMC
Indlela yokusebenzisa
I-viscosity ephansi ye-HPMC ephansi ivame ukunikezwa nge-powder noma ngefomu le-granular futhi ingahlakazwa ngqo emanzini ukuze isetshenziswe.
Ukuvimbela ukulondolozwa kwe-agglomeration, kunconywa ukungeza kancane kancane i-HPMC emanzini abandayo, ivuse ngokulinganayo bese ukushisa ukuncibilikisa ukuthola umphumela ongcono wokuqothula.
Efomula elomile kafulawa, kungaxutshwa ngokulinganayo nezinye izinto eziyimpuphu futhi zingezwe emanzini ukuthuthukisa ukusebenza kahle.
Izidingo Zokugcina
I-HPMC kufanele igcinwe endaweni eyomile, epholile, enomoya omuhle ukugwema izinga lokushisa eliphakeme kanye nomswakama.
Gwema kude ne-oxidants eqinile ukuvikela ukusabela kwamakhemikhali ekudleni izinguquko zokusebenza.
Ukushisa kwesitoreji kunconyelwa ukuthi kulawulwe ngo-0-30 ℃ futhi ugweme ukukhanya kwelanga okuqondile ukuze uqinisekise ukuqina kanye nempilo yenkonzo yomkhiqizo.
I-Viscosisity ephansi i-hydroxypropylyl methylcelluloseidlala indima ebalulekile ezimbonini eziningi ezinjengezinto zokwakha, amakhambi kanye nokudla, izimonyo, ukugcinwa kwemvelo yezolimo ngenxa ye-solubity yayo enhle kakhulu, ukugcinwa kwamanzi, ukugcinwa kwamanzi kanye nezakhiwo ezenziwe ngefilimu. Izici zalo eziphansi ze-viscosity zenza ukuthi ilungele kakhulu izimo zohlelo lokusebenza ezidinga ukubiza, ukungafani kanye nokuqina. Ngokuthuthuka okuqhubekayo kobuchwepheshe bezimboni, insimu yesicelo sokubona okuphansi i-HPMC izokweqiwa futhi, futhi izokhombisa amathemba abanzi ekwenzeni ngcono ukusebenza komkhiqizo kanye nokwenza kahle izinqubo zokukhiqiza.
