Gawo la hydroxypropyl methylcellulose

Hydroxypylropyl (HPMC) ndi gawo losiyanasiyana lomwe limagwira ntchito yofunika kwambiri pakugwiritsa ntchito mitundu yambiri, kuphatikizapo ma purty. Phula limagwiritsidwa ntchito pomanga ndi kugwiritsa ntchito zinthu zosiyanasiyana zamagetsi zodzaza, malo osindikizidwa ndi osalala.

1. Mwachidule za hydroxypropyl methylcellulose (hpmc):

HydroxypropymethylCulose ndi mankhwala opatsirana pa cellulose ochokera ku cellulose, polymer wachilengedwe amapezeka mu makhola a cell. Ntchito yopanga imaphatikizapo kuchitira celluluse ndi alkalis ndi oyang'anira othandizira. Zotsatira za HPMC ndi ufa woyera kapena wopanda ufa womwe umasungunuka m'madzi ndikupanga njira yosinthira ma viscous.

2. Katundu wa hydroxypropyl methylcellulose:

Musanafufuze gawo la HPMC, ndikofunikira kumvetsetsa zofunikira za HPMC:

Kusungunuka kwamadzi: hpmc ndi ma sungunuka amadzi ndikupanga yankho lomveka bwino ndipo limakhazikika pomwe zosakanikirana ndi madzi. Katunduyu amathandizira kukwaniritsa zomwe mukufuna kusintha.

Mafuta owombera: HPMC imakumana ndi mitundu yosinthira, yomwe imatanthawuza kuti mawonedwe ake amawonjezeka akamatenthedwa ndikuchepa pomwe adazizira. Katunduyu ndiwofunika m'mapulogalamu omwe amasintha kutentha kumatha kuchitika pakusakaniza ndi kugwiritsa ntchito.

Mapangidwe a filimu: HPMC imapanga filimu yochepetsetsa, yosinthika ikagwiritsidwa ntchito pamtunda. Katunduyu amathandizira zomatira ndi coutheons's coutheon, kukulitsa magwiridwe ake monga zinthu zochizira pansi.

Thickener: HPMC imagwira ntchito yogwira ntchito yogwira ntchito, kupereka mawonekedwe ofunikira ndi kusasinthika kwa ma purty. Mphamvu yolamulidwa yokulirapo imafalikira mosavuta ndikusuta.

3. Udindo wa hydroxypropyl methylcellulose mwamphamvu:

Kugwiritsa ntchito molimbika: hpmc kumathandizira kugwirira ntchito popanga mawonekedwe osalala komanso osakwanira. Kuwongolera kukula kwamphamvu ndi madzi osasunga kumathandizira kugwiritsa ntchito matenthedwe osiyanasiyana.

Kusunga kwamadzi: chimodzi mwazofunikira za HPMC mu purtems ndi kuthekera kwake kusunga madzi. Izi zimalepheretsa kutsuka kubuluka msanga, kuonetsetsa nthawi yokwanira yogwiritsira ntchito, kuwumba ndi kumaliza. Kusunga kwamadzi kumathandizanso kukulitsa chotsatsa komanso kugwirizanitsa katundu.

Zotsatira ndi Coute: HPMC imalimbikitsa zotsatsa popanga filimu yopyapyala padziko lapansi, yolimbikitsa mgwirizano pakati pa Detty ndi Invu. Kuphatikiza apo, zokongoletsera za hpmc zimathandizira kulimbitsa mphamvu zonse ndi kukhazikika kwa mtengo.

Kuchepetsa: shrazage ndi vuto wamba pamapangidwe ake ndipo imatha kuyambitsa ming'alu ndi kupanda ungwiro pamwamba. HPMC imathandizira kuchepetsa shrinkage ndikuwongolera madzi osinthika pamadzi owuma, zomwe zimapangitsa kuti pakhale zolimba kwambiri zomwe zimatsutsana kwambiri.

Kukhazikika Kokhazikika: Malo opangira mafuta a hpmc amatha kuwongolera nthawi yokhazikitsa. Izi ndizofunikira pakugwiritsa ntchito komwe nthawi inayake zimafunikira kuti pasungunuke.

4. Ubwino wogwiritsa ntchito hydroxypypyl methylcellulose kuti:

Kusiyanitsa: hpmc titha kuphatikizidwa ndi mitundu yosiyanasiyana, ndikupangitsa kukhala koyenera mapulogalamu osiyanasiyana ngati khoma la putty, nkhuni ndi kunja kwa khoma lakunja.

Kukweza kwamphamvu: Zomatira za HPMC ndi zomatira zimathandizira kuti pakhale nthawi yayitali komanso kuchepetsa mwayi wa ming'alu ndi chilema pakapita nthawi.

Kugwirizana ndi zina zowonjezera: HPMC ikugwirizana ndi zowonjezera zowonjezera ndipo ma <2feeo omwe amagwiritsidwa ntchito m'makampani ophatikizika, kulola kutembenuka pazomwe zimachitika.

Maganizo a chilengedwe: monga cellulose yochokera ku Cellulose, hpmc nthawi zambiri zimaganiziridwa kukhala wochezeka. Ndi biodegged ndipo samayambitsa kuipitsidwa kwambiri kwa chilengedwe.

5. Ntchito Zina Kuposa Matenje:

Makampani omanga: Kuphatikiza pa Dekety, hpmc imagwiritsidwa ntchito kwambiri m'malaya osiyanasiyana, kuphatikizapo mafoni, zomatira ndi matae a tiles, kusungira madzi komanso kulimba.

Mankhwala ogulitsa: hpmc amagwiritsidwa ntchito ngati binder, kusinthitsa filimu ndi filimu yolumikizira mankhwala opangira mankhwala chifukwa cha kusungunuka kwake komanso kuwongolera katundu.

Makampani Ogulitsa Chakudya: Makampani ogulitsa zakudya, hpmc amagwiritsidwa ntchito ngati thiccener, ribiliface ndi emulsifier mu zinthu monga msuzi, mchere ndi zinthu zophika ndi zinthu zophika.

6. Kumaliza:

Hydroxypypyl methylcellulose ndi polima molima omwe amachita mbali yofunika kwambiri pakupanga puta. Zosiyanasiyana zake zapadera, kuphatikizapo madzi osungunuka, mafuta owonda ndi mawonekedwe a filimu, thandizo la kugwirira ntchito, kutsatira ndi kulimba kwa oterera. Monga gawo lofunikira la zomangira, hpmc likupitiliza kupeza ntchito zomwe sizingatheke m'mafakitale osiyanasiyana, kuwonetsa kuti anali ndi zinthu zosiyanasiyana pakupanga makono. Kafukufuku wopitilira ndi chitukuko pamunda wa polymer sayansi imatha kubweretsa zina zowonjezera zomwe zidzakulitsa njira zamtsogolo za hydroxypropyll meth.
