MetHylcellose (MC) uye HydroxyPropyl methylcellose (HPMC) miviri yakajairika cellulose derivatives ine mamwe misiyano yakakosha mumakemikari mamiriro uye nzvimbo dzekushandisa. Heino kuenzanisa kwakazara nezvavo:
1. Makemikari maitiro akasiyana
MetHylcellose (MC):
MetHylcellose ndeye cellulose dervative yakagadzirwa nekuunza methyl (-ch₃) mapoka mune zvakasikwa maneja mamorekuru. Mamwe maHydroxyl Mapoka (-OOH) muCellulose Molecule anochinjirwa nemamita methyl (-Och₃) kuumba methylose. Kazhinji mwero we methylation ye methylcellose ndeye 1.5 kusvika ku2,5 methyl mapoka.
Hydroxyprusyl methylcellose (HPMC):
HydroxyPropyl methylcellose is a cellulose inobviswa iyo inowedzera kuburitsa hydroxyprosl Iyo yekutanga yeHydroxyPropyl mapoka inoita HPMC ine nani solubility uye yakakura mashandiro. Chimiro chavo chemakemikari chine maviri akaenzana, methyl uye hydroxyprupropyl.
2. Misiyano mukugadzirisa
Methylcellulose (MC) ine yakasimba mvura solubility, kunyanya mumvura inodziya, inogona kuumba mhinduro ye collodal. Yayo solubility inotsamira pane iyo degree remaghylation. Yakakwira iyo degree remuimbi, zvirinani kuti mvura salubility.
Hydroxyprusyl methylcellose (HPMC) ine iri nani mvura solubility pane methylcellose. Nekuda kwekutanga kweiyo hydroxyprupropropyl mapoka, HPMC inogona zvakare kunyungudusa mumvura inotonhora. Kuenzaniswa ne methylcellose, HPMC ine yakasarudzika solubility, kunyanya inogona kunyungudika nekukurumidza kupisa.
3. Misiyano muzvivakwa zvemuviri
MetHylcellose (MC) kazhinji haina ruvara kune chena poda kana granules, uye mhinduro ndeye viscous, ine emulsification yakanaka, yakakora uye inokomberedza zvivakwa. Mune mimwe mhinduro, methylcellose inogona kuumba yakakura kwazvo gel, asi "gel rupture" inoitika kana ichipiswa.
Hydroxyprusyl methylcellose (HPMC) ine yepamusoro yekugadzirisa viscosity uye zviri nani yekudzikisira. HPMC Solutions inowanzo kuve yakagadzikana pamusoro peiyo yakawedzera pH Range uye usarasikirwa nezvivakwa zvavo kana ichitsveneswa kunge mc, saka inoshandiswa zvakanyanya mune zvinopisa-zvinogadzirwa zvigadzirwa.
4. Masvondo ekushandisa
Nekuda kwesarudzo yavo yakasarudzika yekunyama uye yemuviri, methylcellose uye hydroxypruppropyl methylcellose inoshandiswa zvakanyanya muminda dzakasiyana:
MetHylcellose (MC):
Semunhu akasarudzika, emulsifieri uye stabilizer, inoshandiswa zvakanyanya muindasitiri yechikafu, cosmetics uye mishonga yemishonga.
Muzvivakwa zvekuvaka, MC inowanzo shandiswa mumasumbi, Gypsum, tile inonamira uye zvimwe zvigadzirwa semvura inochengetedza mumiriri uye thickener.
Iyo inoshandiswawo seyakawedzera yekuunganidzwa uye inks.
Hydroxyprusyl methylcellose (HPMC):
Semurume akabatana, emulsifieri uye stabilizer, HPMC inoshandiswa zvakanyanya muindasitiri yemishonga yemishonga, kunyanya mune inogadzirira zvinodhaka.
Muindasitiri yekuvaka, HPMC inoshandiswa mumadziro emadziro, yakaoma yakaoma, tile inonamira uye zvimwe zvigadzirwa kupa kufurirwa zviri nani uye kupikisa kwemvura.
Muindasitiri yekudya, HPMC inowanzoshandiswa seanoti, stabilizer, emulsifier, nezvimwe.
Mune cosmetics, hpmc inogona kushandiswa seyakavhurwa, Gel aimbova, nezvimwe.
5. Kugadzikana uye kupisa kupokana
Methylcellose (mc) inoteerera kupisa kwakanyanya. Kunyanya kana kupisa, iyo MC Solution inogona kuseka uye kutyoka, zvichikonzera mhinduro isingagadzikane. Iyo inonyanya kuvezwa mumvura inopisa, asi isinganyanyi kusimba mumvura inotonhora.
Kuenzaniswa neMc, HydroxyPropyl methylcellose (HPMC) ine zvirinani kugadzikana uye yakafara pH ACHEMA
6. Mutengo nemusika
Nekuda kweiyo yakaoma yekugadzira maitiro uye yakanyanya mutengo weHPMC, inowanzo kudhura kupfuura methylcellose. Mune zvimwe zvekushandisa nezvimwe zvakaderera zvinodiwa, methylcellose chingave chingangoita sarudzo inobudirira, nepo HPMC yakajairika munzvimbo dzinoda kushanda zvakanyanya, senge mishonga yemishonga uye yakakwirira-yekuita zvekuvakira zvekuvakira.
Kunyangwe ese methylcellose (MC) uye hydroxyprusyl methylcellose (HPMC) anoshandisa kubva muminda yakawanda, zvivakwa zvavo zvemakemikari, Solubility uye minda yemuviri uye minda yekushandisa yakasiyana. HPMC inoshandiswa zvakanyanya muminda yakawanda (senge mishonga yemishonga, yekuvaka uye maindasitiri ekushandura) nekuda kwekunyora kwayo kwekunyora, nepo mc ichishandiswa mune zvimwe zvinodhura-zvinonyadzisa.
