Methylcellulose yuav tsis yog tsev neeg lub npe, tab sis nws yog ib qho kev siv tshuaj polymer ntau yam thiab kev lag luam ua noj thiab ua noj. Nws cov tshuaj tshwj xeeb ua rau nws cov khoom zoo tshaj plaws rau ntau yam ntawm kev siv, los ntawm cov kua yas tuab kom tsim cov tshuaj loog. Tab sis dab tsi tiag teeb methylcellulose sib nrug los ntawm lwm cov ntaub ntawv yog nws muaj peev xwm tiv taus tag nrho plaub lub caij.
Ua ntej peb ntswj rau hauv kev tshawb fawb tom qab methylcellulose, cia thawj zaug tham txog nws yog dab tsi thiab nws los ntawm. Methylcellulose yog ib hom cellulose ether derived los ntawm cellulose, lub ntuj polymer pom hauv tsob ntoo phab ntsa. Cellulose yog ib qho ntawm cov organic ntau tshaj plaws hauv ntiaj teb thiab muaj nyob hauv ntau qhov chaw sib txawv, suav nrog ntoo pulp, paj rwb thiab xyoob. Methylcellulose yog tsim los ntawm kev siv cellulation cellulose nrog methyl pawg, uas hloov nws cov khoom thiab ua rau nws ntau soluble hauv dej.
Tam sim no, cia peb tham txog dab tsi ua rau methylcellose tshwj xeeb heev. Ib qho ntawm cov khoom tshwj xeeb tshaj plaws ntawm methylcellulose yog nws lub peev xwm los ua ib gel thaum nws los rau hauv kev sib cuag nrog dej. Qhov kev gelation no tshwm sim vim tias cov methyl pawg rau ntawm cellulose molecules tsim cov txheej txheem hydrophobic uas cov roj hmab dej lwg me me. Yog li ntawd thaum methylcellulose ntxiv rau dej, nws tsim cov tshuaj pleev roj pleev li uas tuaj yeem siv rau cov kev daws teeb meem tuab, ua cov yeeb yaj kiab uas tsis muaj qab hau.
Tab sis dab tsi tiag teeb me me methylcellulose sib nrug yog nws lub peev xwm los tiv thaiv cov kev cuam tshuam ntawm tag nrho plaub lub caij. Qhov no yog vim nws tus cwj pwm tshwj xeeb ntawm ntau qhov kub. Ntawm tsawg kub, xws li nyob rau lub caij ntuj no, me me Methylculose ua cov khoom muaj zog thiab nyuaj. Qhov no ua rau nws ib cov khoom zoo tshaj plaws rau kev tsim cov txheej txheej rau cov tshuaj pleev rau cov tshuaj thiab lwm yam khoom uas xav tau kev tiv thaiv los ntawm noo noo thiab lwm qhov chaw ib puag ncig.
Txawm li cas los xij, raws li qhov kub nce ntxiv, me methylcellulose yuav pib muag muag thiab ua kom tau yooj yim. Qhov no yog vim hais tias raws li kubatures sawv, lub hydrophobic Barrier tsim los ntawm methyl pawg yuav tsis muaj txiaj ntsig zoo ntawm cov roj av lwg me me. Raws li ib tug tshwm sim, cov gel zoo li loj tsim los ntawm methylcellulose yuav tsis tshua muaj zog thiab ntau pliable, ua rau nws tuaj pwm thiab cov duab.
Thaum lub caij ntuj sov, me me Methylulose los ua cov pliable ntau dua, ua rau nws ib qho khoom zoo rau cov khoom siv tsis tau xws li cov nqaij tsis noj. Nws kuj tseem siv tau los ua tus neeg sawv cev ua kom tuab hauv cov kua thiab kua zaub vim nws tseem ruaj khov txawm tias muaj qhov kub.
Ib qho ntawm qhov tseem ceeb tshaj plaws ntawm methylcellulose yog nws lub peev xwm los nyob ruaj khov rau lub sijhawm. Tsis zoo li lwm cov ntaub ntawv uas tuaj yeem ua rau muaj kev tawm tsam lossis rhuav tshem lub sijhawm, methylcellulose yuav khaws nws cov khoom rau xyoo, ua nws cov ntaub ntawv zoo tshaj plaws rau kev siv ntev. Qhov no yog qhov tshwj xeeb tshaj yog rau kev lag luam xws li cov chaw tshuaj thiab cov tshuaj pleev ib ce, qhov khoom yuav tsum tswj hwm lawv cov txiaj ntsig tau thiab lub sijhawm ntev.
Lwm qhov zoo dua ntawm methyleculose yog nws kev nyab xeeb thiab versatility. Nws tau cais los ntawm FDA feem ntau pom tias muaj kev nyab xeeb (gras), uas txhais tau tias muaj kev nyab xeeb rau kev noj haus, tshuaj, thiab tshuaj pleev ib ce, thiab tshuaj pleev ib ce Nws tseem tsis muaj tshuaj lom thiab biodegradable, ua rau nws xaiv ib puag ncig.
Ntxiv rau nws cov kev siv ntau yam kev lag luam, me me methylcellulose kuj yog siv nyob rau hauv kev ua noj ua haus. Qhov tseeb, nws yog cov khoom muaj zog nyob rau hauv ntau vegan thiab cov neeg tsis noj nqaij vim nws lub peev xwm los tsim cov tshuaj pleev ib yam li tsis muaj kev siv tsiaj. Nws yog feem ntau siv los tsim cov khoom cog ntoo uas muaj cov nqaij cog ntoo nrog rau cov khoom ci thiab cov khoom qab zib.
Hauv kev xaus, muaj tseeb methylcellulose yog cov khoom siv zoo dua nrog ntau qhov zoo dua rau lwm cov polymers. Nws lub peev xwm los tiv thaiv txhua plaub lub caij, tswj kev ruaj ntseg nyob rau lub sijhawm, thiab muaj kev nyab xeeb thiab ntau yam rau ntau yam kev lag luam. Seb siv hauv kev tsim cov kws tshuaj, cov tshuaj pleev ib ce lossis cov zaub mov cog qoob loo, me methylenulose yog ib qho tshwj xeeb uas nyob ntawm no.
