Kupanga njira ndi magawo a hpmc

1. Kuyambitsa kwa hydroxypropyl methylcellulose (hpmc)

Hydroxypropyl methylcellulose (hpmc)ndi cellulose yopanda ionic ether yopangidwa kuchokera ku fiber yachilengedwe ya thonje kapena nkhuni zamkati kudzera mu kusintha kwa mankhwala. HPMC ili ndi madzi abwino osungunuka, kukula, kukhazikika, kukhazikika, katundu wamafilimu ndi biovocomit, motero amagwiritsidwa ntchito pomanga, mankhwala, mankhwala, mankhwala tsiku lililonse.

2. Kupanga Njira za HPMC

Kupanga kwa HPMC makamaka kumaphatikizapo njira zotsatirazi:

Kukonzekera Kwa Zinthu

Zinthu zazikulu za HPMC ndizoyera kwambiri zachilengedwe (nthawi zambiri kuchokera ku thonje kapena zamkati zamkati), zomwe zimafuna chithandizo choyambirira chochotsa zodetsa ndikuwonetsetsa kuti cellulose.

Chithandizo cha Alkinization

Ikani cellulose mu riyakitala ndikuwonjezera kuchuluka kwa sodium hydroxide (Naoh) yankho la cellulose malo a alkaline kuti apange cellulose. Izi zitha kuwonjezera ntchito ya cellulose ndikukonzekera zokhudzana ndi zotsatirapo zolimbitsa thupi.

Kuzindikira

Kutengera ndi alkali cellouluse, methylaing othandizira (monga methyl chloride) ndi hydroxypropyypypypypypypypypylaing othandizira (monga Propylene Oxide) amadziwitsidwa. Zomwe zimachitika nthawi zambiri zimachitika mu riyakitala wotseka. Kutentha kwina komanso kukakamizidwa, magulu a hydroxyl pa cellulose ndi methyl ndi hydroxypyl magulu a hydroxypropyll.

Kuchapa kosatha

Pambuyo pochita, malonda atha kukhala ndi mapangidwe osaneneka komanso zopangidwa ndi zinthu, motero ndikofunikira kuwonjezera njira ya acid yothandizira chithandizo, kenako ndikutsuka madzi ambiri kapena zonyansa zochotsa zinthu ndi zosayera.

Kuzama ndi Kuyanika

HPMC yankho la HPMC ndi yosefedwa kapena kusefedwa kuti ichotse madzi ochulukirapo, kenako ukadaulo wowuma kutentha umagwiritsidwa ntchito popanga ufa kapena ma flakes kuti mukhale ndi mphamvu yakuthupi ndi mankhwala a HPMC.

Kupera ndi kuwunika

HPMC youma imatumizidwa ku zida zoguliratu zokhumudwitsa kuti mupeze HPMC ufa wa tinthu tating'onoting'ono. Pambuyo pake, kuwunika ndi magawidwe kumachitika kuti zitsimikizire kuti ma quoform a chinthucho chikakumana ndi zofunikira pakugwiritsa ntchito.

Kusunga ndi Kusunga

Pambuyo pakuyendera bwino, chinthu chomaliza chimakhala ndi magwiridwe osiyanasiyana (monga 25kg / thumba) ndikusungidwa malo owuma komanso opumira kuti mupewe chinyezi kapena kudetsa.

3.. Madera akulu a HPMC

Chifukwa cha kukula kwake, mawonekedwe a filimu, osunga madzi, osunga madzi, mphamvu zowonjezera, hpmc zagwiritsidwa ntchito kwambiri m'mafakitale ambiri:

Makampani omanga

HPMC ndi chowonjezera chowonjezera pazomangira, makamaka zomwe zimagwiritsidwa ntchito:

Matope a simenti: Kupititsa patsogolo madzi omanga, kusintha molunjika, komanso kupewa kutaya madzi ambiri.

Tile zomatira: Kuchulukitsa madzi ogwiritsira ntchito tile ndikusintha magwiridwe antchito.

Zinthu za Gypslum: Sinthani kusokonekera kwa kukana ndi kutembenuka komanga.

Pukuta la putty: Sinthani chotsatsa, kusokonekera kwa kukana ndi luso lotsutsa.

Kudzilimbitsa nokha: Kutulutsa madzi, kuvala kukana ndi kukhazikika.

Makampani opanga mankhwala

HPMC imagwiritsidwa ntchito kwambiri mu gawo la pharmaceutical monga:

Kukuta ndi othandizira makanema a mapiritsi a mankhwala: Kupititsa patsogolo mankhwala osokoneza bongo komanso omasulira mankhwala osokoneza bongo.

Kumasulidwa ndi Kutulutsa-Kutulutsa-Kutulutsa: Kugwiritsa ntchito mapiritsi omasulidwa ndi mapiritsi oyendetsedwa ndi kapisozi kuti alamulireni.

Zolowe m'malo: zogwiritsidwa ntchito popanga makapisozi a masamba (makapisozi).

4. Makampani opanga zakudya

HPMC imagwiritsidwa ntchito ngati chakudya chowonjezera cha:

Thickener ndi emulsifier: ogwiritsidwa ntchito mu zinthu zophika, jellies, souces, etc. kukonza kukoma kwa chakudya.

Stabilizer: Zogwiritsidwa ntchito mu ayisikilimu ndi mkaka kuti muletse kuteteza mpweya.

Zakudya zamasamba: zomwe zimagwiritsidwa ntchito ngati thickiner ya zakudya zopangidwa ndi mbewu kuti zisinthe zokhazikika za nyama monga gelatin.

Tsiku lililonse Mankhwala

HPMC ndi chopangira chofunikira mu zodzikongoletsera komanso zosamalira payekha:

Zogulitsa pakhungu: zogwiritsidwa ntchito mu zotupa, nkhope za nkhope, etc. kuti mupereke chonyowa kunyowa komanso kukhazikika.

Shampoo ndi shawa gel: Kuchulukitsa kukhazikika kwa thovu ndikusintha mafayilo.

Mankhwala: ogwiritsidwa ntchito ngati thickir ndi roinyorizer kukonza kukoma.

Utoto ndi inks

HPMC ili ndi mawonekedwe abwino opanga mafilimu ndi kukhazikika koyimitsidwa ndipo itha kugwiritsidwa ntchito:

Utoto wa mochedwa: Sinthani brushability ndi rheology ya utoto komanso kupewa mpweya.

Inki: Sinthani chiwerewere ndikusintha njira yosindikiza.

Ntchito Zina

HPMC ikhoza kugwiritsidwanso ntchito:

Makampani ogulitsa ma ceramic: ngati chofunda, kusintha mphamvu ya magetsi.

Kulima: Kugwiritsidwa ntchito pakuimika kwa mankhwala ndi zopangira mbewu kuti zithandizire kukhazikika kwa wothandizirayo.

Mafakitale opereka mapepala: Monga kuweta, kusintha madzi kukana ndi kusindikizidwa kwa pepala.

HpmcAmagwiritsidwa ntchito kwambiri poizoni wa polymer, omwe amagwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya, mankhwala tsiku lililonse, zokutira ndi mafakitale ena. Njira zake zimaphatikizira zolaula, kupembedza, kuchapa, kuwuma, kuwuma ndi njira zina, cholumikizira chilichonse chimakhudza mtundu womaliza. Ndi kusintha kwa zofunikira zachilengedwe ndi kukula kwa kufunikira kwa msika, matekinoloje opanga ku HPMC akuthandizidwanso kuti akwaniritse zosowa za mafakitale ambiri.
