Izakhiwo ze-hydroxypropylll methylcellulose

I-Hydroxypropyl Methylcellulose (HPMC) iyinhlangano eguquguqukayo enezicelo ezahlukahlukene ezimbonini ezahlukahlukene, kubandakanya nemithi, ukudla, ukwakha izimonyo, nemikhiqizo yokunakekelwa komuntu. Izakhiwo zalo zenza zilungele ukusetshenziswa okuhlukahlukene, ezisukela ekusebenzeni njengomuntu omkhulu emikhiqizweni yokudla ukuze ukhonze njenge-ejenti yokukhishwa kwemithi.

Isakhiwo se-1.Chical:
I-Hydroxypropylm methylcellulose iyisisulu se-cellulose, i-polymer eyenzeka ngokwemvelo etholakala ezitshalweni. Isakhiwo saso samakhemikhali siqukethe amayunithi aphindaphindwayo ama-molecule we-glucose afakwe esikhundleni namaqembu we-methylypropylyl.
Izinga lokufaka esikhundleni (DS) lazo zombili i-hydroxypropyl kanye namaqembu we-methoxy anquma izakhiwo ze-HPMC. Amanani aphezulu we-DS aphumela ekukhulisekeni kwe-hydrophopobicity kanye nokunciphisa i-solubility yamanzi.

Izakhiwo ze-2.PHysical:
Ukubukeka: I-HPMC imvamisa i-White to off-emhlophe, i-powder emhlophe.
I-Solubinity: Kuyancibilika emanzini abandayo, kepha i-solubity inciphisa ngokwanda kwe-hydroxyproppropylyl kanye namazinga wokungena esikhundleni se-methoxy.
I-Viscosity: Izixazululo ze-HPMC zibonisa ukusebenza kwe-Pseudoplastic noma i-Shear-Twning-Twinning, okusho ukuthi i-visa yazo yehla ngezinga elikhulayo le-Shear. I-Viscosity ingalinganiswa ngokulungisa isisindo se-polymer's molecular kanye nokuhlushwa.
I-Hydration: I-HPMC inesimo esiphakeme sokugcina amanzi, okwenza kube lusizo kuzinhlelo zokusebenza ezidinga ukugcinwa komswakama, njengasezintweni zokwakha.

3.Thermal Properties:
I-HPMC ikhombisa ukuqina okushisayo ngaphezulu kobubanzi bokushisa obubanzi, okuvame ukubola emazingeni okushisa angenhla kwama-200 ° C.
Ukuziphatha kwayo okushisayo kungathintwa yizinto ezifana nezinga lokufaka esikhundleni, ubukhulu bezinhlayiyana, kanye nokuba khona kwezinye izengezo.

Izindawo ze-4.Mechanical:
Amafomu aqinile umthamo, i-HPMC inomthelela emandleni okusebenza kanye nobuqotho bamathebulethi kanye nama-caplule.
Izakhiwo zayo zokwakha amafilimu zizenza zilungele amathebhulethi okuhlanganisa ukuthuthukisa ukugwinya, ukunambitheka kwamamaski nokulawula ukukhishwa kwezidakamizwa.

Izakhiwo ze-5.Rhelogical:
Izisombululo ze-HPMC zibonisa isenzo sokuziphatha esingelona neNewTonian, lapho i-viscosity ishintsha ngokusetshenziswa kwengcindezi noma isilinganiso se-Shear.
Izakhiwo ezi-Rheological ze-HPMC zibalulekile kuzinhlelo zokusebenza ezifana nama-adhesives, lapho zisebenza khona njengoMkhulu futhi zinikeza izici zokugeleza ezifunwayo.

Izakhiwo ezenziwe nge-6.Film:
I-HPMC ingakha amafilimu aguqukayo, amafilimu asobala lapho akhishwe kwisixazululo. Lawa mafilimu athola izicelo ezitsheni zamathebulethi, ama-granule, nemikhiqizo yokudla.
Izakhiwo zefilimu ezinjengamandla ashubile, ukuguquguquka, kanye nesithiyo somswakama kungahle kufanekiswe ngokulungiswa kokugxilisa kwe-polymer kanye nezengezo zokwakhiwa.

I-7.Water Retation:
Enye yezinto ezibalulekile ze-HPMC yikhono layo lokugcina amanzi. Le mpahla iyaxhashazwa kuzicelo ezahlukahlukene, kufaka phakathi izinamathiseli ze-tile, udaka, kanye nemikhiqizo esekwe ku-gypsum, lapho kusiza khona ukugcina ukukwenziwa kanye ne-hydration yezinto ezibonakalayo.

8.Helling and Gelling:
I-HPMC isebenza njenge-ejenti yokuqina ezixazululweni zamanzi, Ukudlulisela i-viscosity kanye nokwenza ngcono ukuthungwa emikhiqizweni efana namasoso, amasobho nezimonyo.
Kwezinye izindlela, i-HPMC ingakha ama-gels ku-hydration, ukuhlinzeka ngesakhiwo nokuqina kumkhiqizo wokugcina.

Ukukhishwa okungu-9.
Emakhishini emithi, i-HPMC isetshenziswa kabanzi njenge-matrix yangaphambili kumafomu wamadosi alawulwayo.
Ikhono layo lokunqwabelanisa nokwakha i-gel ungqimba lisiza ukulawula isilinganiso sokukhishwa kwezidakamizwa, okuvumela ukulethwa kwezidakamizwa okunwetshiwe kanye nokuhambisana kweziguli okuthuthukile.

I-1.comPhila Kuyaqina
I-HPMC iyahambisana nohla olubanzi lwabanye abasebenza ngezengezo kanye nezithasiselo ezisetshenziswa kakhulu ekwenziweni kwemithi nokudla.
Kubonisa ukuqina okuhle ngaphansi kwezimo ezijwayelekile zokugcina, ngengozi encane yokuwohloka kwamakhemikhali noma ukuxhumana nezinye izinto.

11.BinaocomTI Iya:
I-HPMC ngokuvamile ibhekwa njengephephile (GRAS) ukuze isetshenziswe ekusetshenzisweni kwezicelo zokudla kanye nezemithi.
Akuyona into enobuthi, engacasuli, futhi i-biodegradable, okwenza kube lula ukwakheka okuhlukahlukene okuphezulu nowomlomo.

Ithonya le-12.Envirolal:
I-HPMC ithathwe kwizinsizakusebenza ezivuselelekayo, ikakhulukazi ama-soulp we-woodp kanye nama-cotton pulp kanye nokotini, okwenza kube nobungani bemvelo ngokuqhathaniswa namanye ama-polymer athile.
I-biodegradearability yaphinde yehlisa i-footprint yayo yezemvelo, ikakhulukazi ezinsizakalweni ezilahlwayo.

I-Hydroxypropyl Methylcellulose (HPMC) inikezela ngenhlanganisela eyingqayizivele yezakhiwo zomzimba, zamakhemikhali, nezisebenzayo ezenza zibe zibaluleke kakhulu kwizicelo eziningi zezimboni. Ukuguquguquka okuhlukahlukene, ukuqina kokuqina, kanye nokusimama kwemvelo kufaka isandla ekusetshenzisweni kwayo okubanzi kuyo yonke imikhakha ehlukahlukene, kusuka emikhakheni nasekudlayo ekwakheni nasekudlalweni kwezimonyo. Njengoba ucwaningo nobuchwepheshe kuyaqhubeka ukuthuthuka, i-HPMC kungenzeka ihlale isithako esiyisihluthulelo ekwakhekeni kwemikhiqizo emisha okuvela emihlanganweni kanye nezidingo zokulawula.
