Kodi hydroxypropyl methyl cellulose ndi chiyani?

Hydroxypropyl methyl cellulose (HPMC), yomwe imatchedwanso hydroxypropyl methylcellulose, cellulose hydroxypropyl methyl ether, cellulose, 2-hydroxypropylmethyl ether, PROPYLENE GLYCOL ETHER OF METHYLCELLULOSE, CAS No.HPMC akhoza kugawidwa mu kalasi yomanga, kalasi chakudya ndi mankhwala kalasi malinga ndi ntchito yake.Amagwiritsidwa ntchito kwambiri pomanga, chakudya, mankhwala ndi zodzoladzola, mankhwala a tsiku ndi tsiku ndi mafakitale ena.

Kodi HPMC imagwiritsidwa ntchito bwanji?

Makampani omanga

1. Dongo la zomangamanga
Kulimbitsa zomatira pamwamba pamiyala kumatha kupititsa patsogolo kusungidwa kwamadzi, potero kumapangitsa mphamvu yamatope, ndikuwongolera mafuta ndi pulasitiki kuti zithandizire ntchito yomanga.Kumanga kosavuta kumapulumutsa nthawi komanso kumapangitsa kuti ndalama zisamayende bwino.
2. Zida za Gypsum
Ikhoza kutalikitsa nthawi yogwira ntchito yamatope ndikupanga mphamvu zamakina apamwamba panthawi yolimba.Kuphimba kwapamwamba kwapamwamba kumapangidwa ndi kulamulira kusasinthasintha kwa matope.
3. Utoto wamadzi ndi chochotsera utoto
Ikhoza kutalikitsa moyo wa alumali poletsa mvula yolimba, ndipo imakhala ndi kuyanjana kwakukulu komanso kukhazikika kwachilengedwe.Kusungunuka kwake ndikofulumira komanso kosavuta kuphatikizira, zomwe zimathandiza kuchepetsa kusakaniza.Pangani mawonekedwe abwino oyenda, kuphatikiza sipatter yotsika komanso kusanja bwino, onetsetsani kutha kwapamwamba, ndikupewa kugwa kwa utoto.Limbikitsani kukhuthala kwa chochotsa utoto chochokera kumadzi ndi chochotsera utoto chosungunulira cha organic, kuti chochotsa utoto zisatuluke kuchokera pamalowo.
4. Ceramic matailosi zomatira
Zosakaniza zouma zowuma ndizosavuta kusakaniza ndipo siziphatikizana, kupulumutsa nthawi yogwira ntchito chifukwa zimagwiritsidwa ntchito mwachangu komanso mogwira mtima, kuwongolera magwiridwe antchito komanso kuchepetsa ndalama.Limbikitsani magwiridwe antchito a matayilo ndikupereka kumamatira kwabwino kwambiri powonjezera nthawi yozizira.
5. Zida zodziyimira pawokha pansi
Imapereka mamasukidwe akayendedwe ndipo itha kugwiritsidwa ntchito ngati chowonjezera chowongolera kuti chithandizire kukonza bwino kwa pansi.Kuwongolera kusungidwa kwa madzi kumatha kuchepetsa kwambiri ming'alu ndi kuchepa.
6. Kupanga ma slabs opangidwa ndi konkriti
Iwo timapitiriza processability wa mankhwala extruded, ali mkulu kugwirizana mphamvu ndi lubricity, ndi bwino chonyowa mphamvu ndi adhesion wa mapepala extruded.
7. Plate joint filler
Hydroxypropyl methyl cellulose imakhala ndi madzi osungira bwino, imatha kuwonjezera nthawi yoziziritsa, ndipo kuyamwa kwake kumapangitsa kuti ntchitoyo ikhale yosalala.Imawongolera bwino mawonekedwe a pamwamba, imapereka mawonekedwe osalala komanso osalala, ndikupanga malo omangirira kukhala olimba.
8. Gypsum yochokera ku simenti
Zimakhala ndi madzi osungira madzi, zimatalikitsa nthawi yogwira ntchito yamatope, komanso zimatha kulamulira mpweya wolowera, motero kuchotsa ming'alu yaying'ono ya zokutira ndikupanga malo osalala.

Makampani opanga zakudya

1. Zazitini zipatso za citrus: kupewa whitening ndi kuwonongeka chifukwa kuwonongeka kwa citrus glycosides pa yosungirako, kuti tikwaniritse mwatsopano kusunga kwenikweni.
2. Zipatso zoziziritsa kukhosi: zowonjezeredwa ku madzi a zipatso ndi ayezi kuti kukoma kwake kukhale bwino.
3. Msuzi: amagwiritsidwa ntchito ngati emulsion stabilizer kapena thickener wa msuzi ndi phwetekere phala.
4. Kupaka ndi kupukuta madzi ozizira: kumagwiritsidwa ntchito posungira nsomba zachisanu kuti ziteteze kusinthika ndi kuwonongeka kwa khalidwe.Mukapaka ndi kupukuta ndi methyl cellulose kapena hydroxypropyl methyl cellulose amadzimadzi, amaundani pa ayezi wosanjikiza.
5. Zomatira pamapiritsi: Monga zomatira zomangira mapiritsi ndi ma granules, zimakhala bwino "kugwa panthawi imodzi" (kusungunuka mofulumira, kugwa ndi kubalalitsidwa pamene mutenga).

Makampani opanga mankhwala

1. Encapsulation: The encapsulation agent amapangidwa mu njira yothetsera organic zosungunulira kapena amadzimadzi yothetsera piritsi makonzedwe, makamaka kwa kupopera encapsulation wa okonzeka particles.
2. Retarding wothandizira: 2-3 magalamu patsiku, 1-2G nthawi, kwa masiku 4-5.
3. Mankhwala a Ophthalmic: Popeza kuti mphamvu ya osmotic ya methyl cellulose aqueous solution ndi yofanana ndi ya misozi, imakhala yosapweteka kwambiri m'maso.Iwo anawonjezera mu ophthalmic mankhwala monga lubricant kukhudzana ndi diso mandala.
4. Odzola: Amagwiritsidwa ntchito ngati maziko a odzola monga mankhwala akunja kapena mafuta odzola.
5. Inpregnating agent: amagwiritsidwa ntchito ngati thickener ndi kusunga madzi.

Makampani opanga zodzikongoletsera

1. Shampoo: Limbikitsani kukhuthala ndi kukhazikika kwa shampu, chotsukira ndi chotsukira.
2. Otsukira mkamwa: kusintha fluidity wa otsukira mkamwa.

Makampani a Kiln

1. Zida zamagetsi: monga zomatira zomata za ceramic magetsi compactor ndi ferrite bauxite maginito, zitha kugwiritsidwa ntchito limodzi ndi 1.2-propanediol.
2. Mankhwala a glaze: amagwiritsidwa ntchito ngati mankhwala a glaze a ceramics komanso kuphatikiza ndi utoto wa enamel, womwe ukhoza kupititsa patsogolo mgwirizano ndi kusinthika.
3. Mtondo wosungunula: Ukhoza kuwonjezeredwa ku matope a njerwa kapena ng'anjo yamoto kuti upangitse pulasitiki ndi kusunga madzi.

Mafakitale ena

HPMC amagwiritsidwanso ntchito kwambiri mu kupanga utomoni, petrochemical, ziwiya zadothi, kupanga mapepala, zikopa, inki madzi, fodya ndi mafakitale ena.Amagwiritsidwa ntchito ngati thickener, dispersant, binder, emulsifier ndi stabilizer mumakampani opanga nsalu.

Momwe mungadziwire zowoneka bwino za hydroxypropyl methyl cellulose (HPMC)?

1. Chromaticity: ngakhale sichingazindikire mwachindunji ngati HPMC ndi yosavuta kugwiritsa ntchito, ndipo ngati wothandizira woyera akuwonjezeredwa pakupanga, khalidwe lake lidzakhudzidwa.Komabe, zinthu zapamwamba zatsala pang’ono kugulidwa.
2. Fineness: HPMC ili ndi ma meshes 80 ndi ma meshes 100 ambiri, ndipo ma meshes 120 ndi ochepa.Ma HPMC ambiri ali ndi ma meshes 80.Nthawi zambiri, offside fineness ndi bwino.
3. Kutumiza kowala: ikani hydroxypropyl methyl cellulose (Mtengo wa HPMC) m'madzi kuti apange colloid yowonekera, kenako ndikuwona kufalikira kwake.Kuchuluka kwa kuwala kwamagetsi, kumakhala bwinoko, kusonyeza kuti muli ndi zinthu zochepa zosasungunuka mmenemo.
4. Kukoka kwapadera: Kulemera kwa mphamvu yokoka kwapadera, kumakhala bwinoko.Chiŵerengerocho ndi chofunikira, makamaka chifukwa zomwe zili mu hydroxypropyl ndizokwera.Ngati zomwe zili mu hydroxypropyl ndizokwera, kusungirako madzi kumakhala bwinoko.
Hydroxypropyl methyl cellulose ndi yokhazikika ku ma acid ndi maziko, ndipo njira yake yamadzimadzi imakhala yokhazikika pa pH = 2 ~ 12.Ndife akatswiri opanga.Ngati mukufuna mankhwalawa, mutha kulumikizana nafe.Ndizo zonse zogawana ndi HPMC munkhaniyi.Ndikukhulupirira kuti ikhoza kukuthandizani kumvetsetsa HPMC.
