Kodi pali kusiyana kotani pakati pa HPMC ndi Mic?

Hydroxypropyl methylcellulose (hpmc) ndi methyl hydrothyl cellulose (mahec) ndi celloulyl cellulose (Mhec) ndi cellose ellulose (ma ceclose) ndi ma cellulose etralose (Mhec) ndi ma cellulose etralose (Mhec) ndi ma cellulose etralose (ma cerolose) ndi mankhwala osiyanasiyana monga kapangidwe kosiyanasiyana, chakudya, ndi zodzola. Ngakhale kuti amafanana ndi zofanizira ndi ntchito zawo zamankhwala, zomwe zimagwiritsidwa ntchito, pali kusiyana kosiyana pakati pa awiriwa.

1. Mankhwala Osiyanasiyana:

HPMC (hydroxypropyl methylcellulose): HPMC ndi polymer polymer yochokera ku cellulose. Imapangidwa kudzera mu kusintha kwa mankhwala kwa cellulose, makamaka kumachotsedwa ku mitengo yamtengo wapatali kapena ya thonje. Kusintha kwa cellulose ndi alkali, kutsatiridwa ndi ma puronne oxide ndi methyl chloride kuti ayambitse ma hydroxypyl ndi ma medyl mafupa am'madzi.

Mithc (methyl hydrothyl cellulose): Micheyi ndi cellulose eyal exuluse yopezeka kudzera mu kusintha kwamankhwala kwa cellulose. Zofanana ndi HPMC, zimachitika zolimbitsa thupi kuti ziziyambitsa methyl ndi ma hydroxyethyl magulu am'madzi a cellulose. Mic amapangidwa ndi kuchiritsa cellulose ndi alkali, kutsatiridwa ndi nkumathanth ndi methyl chloride ndi ethylene oxide.

2. Kapangidwe ka mankhwala:

Pomwe onse a HPMC ndi Ahec adagawana msana wa cellulose, amasiyana mu mtundu ndikupanga magulu olowa m'malo omwe adaphatikizidwa ndi msana wakumbuyo.

Kapangidwe ka HPMC:
Magulu a hydroxypyl (-ch2choch3) ndi magulu a methyl (-ch3) amatumizidwa mwachisawawa m'mphepete mwa ma cellulose.
Chiwerengero cha hydroxypropyl m'magulu osiyanasiyana amasiyanasiyana kutengera njira yopanga ndi katundu womwe mukufuna.

Kapangidwe ka MEC:
Methyl ndi hydroxyethyl magulu (-ch2choch3) amaphatikizidwa ndi msana wakubwerera kwa cellulose.
Chiwerengero cha methyl kwa magulu a hydroxyethyl amatha kusinthidwa pa synthesis kuti akwaniritse katundu.

3. katundu:

Katundu wa HPMC:
HPMC imawonetsa kusungunuka kwamadzi ambiri, ndikupanga njira zowonekera komanso zowoneka bwino.
Ili ndi katundu wabwino kwambiri wamakanema, ndikupanga kukhala koyenera kugwiritsa ntchito filimu.
HPMC imapereka zomatira zabwino komanso zomangira, zimathandizira chilengedwe pamitundu yosiyanasiyana.
Makutu a HPMC mayankho a HPMC imatha kukhala yolumikizidwa ndikusintha kuchuluka kwa zolowa m'malo mwazowonjezera komanso kunenepa.

Mitundu ya Mic:
Komabec amawonetsa kusiyanasiyana madzi, koma kusungunuka kwake kumatha kusiyanasiyana malinga ndi kuchuluka kwa milingo yokhazikika komanso kutentha.
Imatanthawuza mayankho omveka bwino ndi pseudoplastiction, kuwonetsa katundu wamphongo.
Mic imapereka zipatso zabwino kwambiri komanso zolimbitsa thupi mokhazikika.
Monga HPMC, mawidwe a mayankho a mhec amatha kuwongoleredwa posintha kuchuluka kwa mizere yolowa m'malo mwazowonjezera.

4. Mapulogalamu:

Ntchito za HPMC:
Makampani omanga: HPMC imagwiritsidwa ntchito kwambiri m'matayala a simenti, gypsum-poschents, ndi tiles kuti musinthe madzi, kusungidwa kwamadzi, komanso kutsatira.
Mankhwala ogwiritsa ntchito mankhwala: hpmc amagwiritsidwa ntchito mu ma piritsi, amasulidwa, kumasulidwa, mafinya a ophthalmic, komanso kukonzekera kwapamwamba chifukwa cha mawonekedwe ake ndi njira.
Chakudya ndi zodzikongoletsera: HPMC imagwira ntchito yokulirapo, kukhazikika, ndi emulsiferier mu chakudya, zinthu zaumwini, komanso zodzola.

Mapulogalamu a Mic:
Makampani omanga: Miche amagwiritsidwa ntchito kwambiri mu mawonekedwe a tiles, amatembenuza, ndipo amasoweka popititsa madzi, othandiza, komanso kutsatira.
Utoto ndi zokutira: Mic imagwiritsidwa ntchito ngati rheology yosintha mumawu, zokutira, ndi inks kuti muwongolere mafakisoni, pewani kusamba, ndikusintha katundu.
Mapangidwe a mankhwala

5. Zabwino:

Ubwino wa HPMC:
HPMC imapereka katundu wapamwamba wopanga mawonekedwe, ndikupangitsa kukhala koyenera matebulo ndi mapangidwe omasulidwa.
Imawonetsa zabwino kwambiri komanso mawonekedwe omangirira, kukulitsa chilumi cha mapangidwe osiyanasiyana.
HPMC imaperekanso kusinthasintha kusintha ma viscction ndikusintha njira.

Ubwino wa Mhec:
Mhec akuwonetsa kukula kwapadera komanso kukhazikika pamiyambo yam'madzi, kumapangitsa kuti zikhale zabwino utoto, zomanga, ndi mankhwala opanga mankhwala.
Imaperekanso malo abwino osungirako madzi, kukonza kugwirira ntchito ndi kutsatira kwa zinthu za simenti.
Athec amapereka machitidwe a pseudoplactic, kulola kugwiritsa ntchito kosavuta kugwiritsa ntchito zokutira ndi zokutira.

Ngakhale onse a HPMC ndi Miche ndi cellose yofananira ndi mapulogalamu ofanana, akuwonetsa kusiyana m'magulu awo, zomangidwa, katundu, ndi zabwino. HPMC imadziwika chifukwa cha mawonekedwe ake abwino kwambiri komanso zotsatsa, pomwe Miches amachita bwino kwambiri, kukhazikika, komanso madzi osunga madzi. Kuzindikira zokhumudwitsa izi ndikofunikira posankha ethel ether forsic forsictions pamafakitale osiyanasiyana.
