Methylcelose (MC) da Hydroxypolyl methylcellulopyl methylcels (hpmc) sel biyu ne na yau da kullun sel sel waɗanda suke da wasu bambance-bambance masu mahimmanci a tsarin sunadarai da wuraren aikace-aikace. Ga cikakken kwatancen su:
1. Bambance bambancen sunadarai
Methylcellulose (MC):
Methylcellulose ne mai narkewa ne ta hanyar gabatar da ƙungiyoyi na methyl (-ch₃) a cikin kwayoyin sukan kwastoman na halitta. Wasu rukunnan Hydroxyl (-Oh) a cikin kwayar sel sel smallet an maye gurbinsu da kungiyoyin methyl (-Och₃) don samar da methylcelse. Yawancin lokaci mataki na methylation na methylellulose kusan 1.5 zuwa 2.5 Metyl ƙungiyoyi.
Hydroxypyl methylcelos (hpmc):
Rydroxypyl methypulose ne sel mai sel wanda ya kara gabatar da kungiyoyi hydroxypropyl (-c₃h₇) kungiyoyin kan batun methylcellulose. Gabatarwar kungiyoyin Hydroxypyl sun sa HPMC suna da mafi kyawun ƙima da aikin yaduwa. Tsarin sunadarai ya ƙunshi siyar-sau biyu, methyl da hydroxypropyl.
2. Bambanci a cikin karuwa
Methylcellulose (MC) yana da karfin ruwa mai ƙarfi, musamman a cikin ruwa mai ɗumi, yana iya samar da mafita mai narkewa. Sililinsa ya dogara da matsayin methylation. A mafi girman digiri na methylation, mafi kyawun kayan ruwa.
Hydroxypyl methylcellose (hpmc) yana da mafi kyawun abinci na ruwa fiye da methylellelle. Saboda gabatarwar Hydroxypyl ƙungiyoyi, HPMC na iya narkewa sosai a cikin ruwan sanyi. Idan aka kwatanta da methylcellulose, HPMC yana da mafi girman solila, musamman zai iya narke cikin sauri a yanayin zafi.
3. Bambance-bambance a cikin kaddarorin jiki
Methylcellulose (MC) yawanci mai launi ne ga farin foda ko granules, da mafita mai viscous, tare da kyakkyawan emulsification, thickening da gloling kaddarorin. A wasu mafita, methylcellulose na iya samar da ingantaccen gel, amma "gel ya rusa" yana faruwa lokacin da ya mai zafi.
Hydroxypyl methylcelose (HPMC) yana da ingantaccen danko da ingantaccen kwanciyar hankali. HPMC mafita ana iya tsayayye akan mafi fadi da PH, kuma kada ku rasa kaddarorin Glering lokacin da mai zafi kamar MC, don haka ana amfani dashi a samfuran mai zafi.
4. Filayen aikace-aikacen
Saboda kayan aikinsu na musamman da kaddarorinsu na jiki, methylcellulopyl methylcellulopyl methylcellulose ana amfani dashi sosai a filaye daban-daban:
Methylcellulose (MC):
A matsayina mai kauri, emulsifier da mai shayarwa, ana yadu sosai a masana'antar abinci, kayan kwaskwarima da magunguna.
A cikin kayan gini, ana amfani da MC sau da yawa a cikin ciminti, gypsum, talaariyar talauta da sauran kayayyaki azaman mai riƙe da ruwa da kuka da kuka.
Hakanan ana amfani dashi azaman kayan kwalliya don cox da inks.
Hydroxypyl methylcelos (hpmc):
A matsayin kauri, emulsifier da maimaitawar masana'antu, ana amfani da HPMC sosai a cikin masana'antar magunguna, musamman a cikin shirye-shiryen saki ne.
A cikin masana'antar gine-ginen, ana amfani da HPMC a cikin mayafin bango, turmi bushe, tayal ti adhesive da sauran samfuran don samar da ingantacciyar tasirin da.
A cikin masana'antar abinci, ana amfani da HPMC azaman thickenner, mai tsafta, emulsifier, da sauransu.
A cikin kayan shafawa, za'a iya amfani da HPMC azaman humact, gel tsohon, da sauransu.
5. Jira da juriya na zafi
Methylcellulose (MC) yana da hankali ga yanayin zafi. Musamman lokacin da aka mai tsanani, MC bayani na iya gel da karya, sakamakon shi ne mafita. Ya fi narkewa a cikin ruwan zafi, amma ƙasa da narkewa a cikin ruwan sanyi.
Idan aka kwatanta da MC, Hydroxypropyl methylcellulam (hpmc) yana da mafi kyawun daidaitaccen kwanciyar hankali da kuma iya yin amfani da shi a cikin samfuran zazzabi.
6. Farashi da kasuwa
Saboda tsari mai rikitarwa da tsari da tsada mai tsada na HPMC, yawanci yafi tsada fiye da methylellelle. A wasu aikace-aikace tare da ƙananan buƙatun, methylcellulose na iya zama mafi kyawun farashi, yayin da HPMC ya fi kowa kyau a wuraren da ke buƙatar mafi girma, kamar manyan ayyukan gini da kayan gini.
Duk da cewa duka methylcellulose (MC) da hydroxypropyl methylcellulose (HPMC) an samo shi ne daga sel na asali, tsarin sunadarai da filayen aikace-aikacen sun bambanta. HPMC ana amfani dashi sosai a cikin filaye da yawa (kamar masana'antu na kayan gini da kayan kwalliya) saboda kwanciyar hankali da kwanciyar hankali, yayin da MC ya fi amfani da su a cikin aikace-aikacen da suka dace.
