Hydroxypropyl methylcellulose (hpmc)

Hydroxypypyl methylcellulose (hpmc) Amagwiritsidwa ntchito kwambiri pamafashoni osiyanasiyana pazopadera zake, kuphatikizapo zamankhwala, zomanga, chakudya, zodzola, komanso chisamaliro chaumwini. Mu chitsogozo chokwanira ichi, tifufuza kapangidwe ka mankhwala, katundu, kupanga, kugwiritsa ntchito, komanso mapindu a HPMC mwatsatanetsatane.

1. Kuyambitsa kwa HPMC:

Hydroxypypyl methylcellulose (hpmc) ndi ma cellulose ether ether ochokera ku cellulose yachilengedwe kudzera mu kusintha mankhwala. Imapangidwa ndi kuchiritsa cellulose ndi ma propely oxide ndi methyl chloride kuti ayambitse hydroxypropyl ndi methyl magulu am'madzi am'madzi. Polymer yotsatirayi ikuwonetsa mitundu yambiri yomwe imapangitsa kuti ikhale yofunika kwambiri pakugwiritsa ntchito mafakitale.

2. Kapangidwe ka mankhwala ndi katundu:

HPMC imadziwika ndi kapangidwe kake, yomwe imakhala ndi msana wa cellulose ndi hydroxyppyl ndi methyl ophatikizidwa ndi magulu a hydroxyl. Mulingo wa zolowa m'malo mwa hydroxypyl ndi methyl amatha kukhala osiyanasiyana, chifukwa chosiyana ndi zinthu zina za HPMC yokhala ndi mawonekedwe, kusamukira, ndi jolation.

Katundu wa HPMC amatengera zinthu monga kulemera kwa ma celecular kulemera, digiri ya kuloweza, ndi hydroxypropyl / methyl kuchuluka. Nthawi zambiri, hpmc imawonetsa zinthu zotsatirazi:

• Madzi - Kusungunuka
• Luso lopanga filimu
• Kukula ndi kuthira katundu
• Zochitika zapamwamba
• Kukhazikika pa Phokoso Lalikulu
• Kugwirizana ndi Zipangizo Zina

3. Kupanga:

Kupanga kwa HPMC kumaphatikizapo njira zingapo, kuphatikiza:

1. Kukonzekera kwa cellulose: cellulose wachilengedwe, wowonjezeka kwambiri kuchokera ku prglyp kapena thonje, wotsukidwa, umayeretsedwa ndikuyengeka kuti achotse zodetsa ndi kubisa.
2. Kuzindikira Kuchita: Ma cellulose amathandizidwa ndi ma propyl oxide ndi methyl chloride pamaso pa alkali a caltalysts kuti ayambitse ma busroxypyl am'mimba.
3. Kusinthana ndi kuchapa: zotsatira zake sizimalowerera kuloza alkali kenako kutsukidwa kuti muchotse zopangidwa ndi zosayera.
4. Kuyanika ndi Kupukuta: HPMC yoyeretsedwa imawuma ndikuyika mu ufa wabwino woyenera kugwiritsa ntchito zinthu zosiyanasiyana.

4. Maphunziro ndi zochitika:

HPMC imapezeka pamitundu yosiyanasiyana ndikukwaniritsa zofunikira zingapo zamakampani osiyanasiyana ndi ntchito. Izi zikuphatikiza kusiyanasiyana m'matumbo, kukula kwa tinthu, kuchuluka kwa kuloweza, ndi kutentha kwa kutentha. Makulidwe a HPMC amaphatikizapo:

• Makina owoneka bwino (mwachitsanzo, 4000 cps, 6000 cps)
• Makulidwe apamwamba kwambiri (mwachitsanzo, 15000 cpps, 20000 cps)
• Makulidwe otsika (mwachitsanzo, 1000 CPS, 2000 CPS)
• Makunja apadera azinthu zapadera (mwachitsanzo, kumasulidwa, kumasulidwa kovomerezeka)

5. Ntchito za HPMC:

HPMC imapeza kugwiritsa ntchito mafakitale osiyanasiyana chifukwa cha malo omwe ali ndi zinthu zosiyanasiyana. Ena mwa mapulogalamu ofunikira a HPMC amaphatikiza:

a. Makampani opanga mankhwala:

• Piritsi ndi mapikoleti
• Mapangidwe omasulidwa
• Mangani ndi kusokoneza mapiritsi
• Ophthalmic ndi kuyimitsidwa
• Mitundu yapamwamba monga mafuta ndi mafuta

b. Makampani omanga:

• Zogulitsa za Smentam ndi GypShum (mwachitsanzo, matope, mazira)
• Zilonda za Tile ndi Zopukutira
• Kutayika kunja ndi kumaliza kachitidwe (magwiritsidwe)
• Zodzikongoletsera zokha
• Utoto wochokera m'madzi ndi zokutira

c. Makampani Ogulitsa Chakudya:

• Kukula ndi kukhazikika mu chakudya
• Emulsiferier ndi kuyimilira othandizila kusuntha ndi zovala
• Zowonjezera zowonjezera
• Gluten-free ndi confectionery

d. Chisamaliro chaumwini ndi zodzikongoletsera:

• Thickener ndikuyimitsa wothandizila kudzoza ndi mafuta
• Makanema ndi filimu-yemwe ali m'zogulitsa za tsitsi
• Kulamulidwa Kutulutsidwa M'mitundu Yakale
• Maso amaso ndi ma lens okonda a mandala

6. Ubwino wogwiritsa ntchito HPMC:

Kugwiritsa ntchito HPMC kumapereka mapindu angapo pamakampani osiyanasiyana:

• Kugwiritsa ntchito magwiridwe antchito ndi mtundu
• Kukulitsa kusinthasinthasintha ndi kukhazikika
• Moyo wowonjezera ndi wochepetsedwa
• Njira yolimbikitsidwa ndi njira yotsika mtengo
• Kugwirizana ndi Zofunikira Zowongolera ndi Zotetezedwa
• Zachilengedwe Zachilengedwe ndi Biocomlam

7.. Zochita zamtsogolo ndi malingaliro:

Kufunikira kwa HPMC kumayenera kupitiliza kukula, kumayendetsedwa ndi zinthu monga momwe zimapangidwira kutukuka kwa kutukuka, ndikufunira zinthu zamankhwala. Kufufuza kosalekeza ndi kuyesetsa kwa chitukuko kumayang'ana pakukulitsa mapangidwe a HPMC, kukulitsa ntchito zake, ndikusintha njira zopangira kusinthana kwamisika.

8. Kumaliza:

Hydroxypypyl methylcellulose (hpmc) ndi polymer yosiyanasiyana ndi ntchito zosiyanasiyana pamakampani angapo. Malo ake apadera, monga kusungunuka kwamadzi, kuthekera kanema, ndi katundu thizaticals, kumanga, chakudya, chisamaliro chaumwini, komanso zodzola. Pamene kupita patsogolo kwaukadaulo ndi msika kumafunikira kusintha, HPMC ikuyembekezeka kuchita mbali yofunika kwambiri posokoneza tsogolo la mafakitale osiyanasiyana.
