Methylcellulose wani nau'in cellulose ne mai narkewa da ruwa wanda ake amfani dashi sosai a abinci, magani, kayan kwalliya, gini da masana'antu. Yana da ayyuka daban-daban irin su kauri, emulsification, riƙe ruwa, da ƙirƙirar fim, amma aikace-aikacen sa yana tare da wasu gazawa da gazawa.
1. Matsalolin narkewa
Methylcellulose abu ne mai narkewa da ruwa, amma zafinsa yana da tasiri sosai. Gabaɗaya magana, methylcellulose yana narkewa da kyau a cikin ruwan sanyi, yana samar da bayani mai haske. Duk da haka, lokacin da yawan zafin jiki ya tashi zuwa wani matakin, solubility na methylcellulose zai ragu kuma ko da gelation zai faru. Wannan yana nufin cewa ana iya iyakance amfani da methylcellulose a wasu aikace-aikacen zafin jiki, kamar wasu sarrafa abinci ko hanyoyin masana'antu.
2. Rashin juriya na acid da alkali
Methylcellulose yana da ƙarancin kwanciyar hankali a cikin yanayi mai ƙarfi na acidic ko alkaline. A ƙarƙashin matsanancin yanayin pH, methylcellulose na iya ƙasƙanta ko canza sinadarai, ya rasa kayan aikinsa. Misali, danko na methylcellulose na iya raguwa sosai a karkashin yanayin acidic, wanda shine babban hasara ga aikace-aikace inda ake buƙatar daidaiton daidaito, kamar kayan abinci ko magunguna. Sabili da haka, tasirin methylcellulose zai iya shafar lokacin da ake buƙatar kwanciyar hankali na dogon lokaci ko lokacin amfani da shi a cikin yanayi tare da pH maras tabbas.
3. Mummunan yanayin halitta
Ko da yake ana ɗaukar methylcellulose a matsayin wani abu mai dacewa da muhalli saboda an samo shi daga cellulose na halitta kuma ba shi da guba kuma ba shi da lahani, biodegradability nasa bai dace ba. Saboda methylcellulose an gyare-gyare ta hanyar sinadarai a cikin tsari, ƙimar lalacewa a cikin yanayin halitta yana da ƙasa da ƙasa fiye da na cellulose na halitta. Wannan na iya haifar da tarin methylcellulose a cikin mahalli, musamman idan aka yi amfani da shi da yawa, tare da tasiri mai tasiri akan tsarin halittu.
4. Iyakar kayan aikin injiniya
Methylcellulose baya yin aiki da kyau a wasu aikace-aikacen da ke buƙatar ƙarfi mai ƙarfi ko kayan aikin injiniya na musamman. Ko da yake yana iya samar da fina-finai ko kauri mafita, waɗannan kayan suna da ƙarancin ƙarfin inji, juriya da kaddarorin ɗaure. Misali, a cikin kayan gini ko kayan kwalliya masu inganci, methylcellulose bazai samar da ƙarfin da ake buƙata ko dorewa ba, yana iyakance kewayon aikace-aikacen sa.
5. Mafi tsada
Farashin samar da methylcellulose yana da inganci, musamman saboda hadadden tsarin samarwa wanda ke buƙatar gyaran sinadarai na cellulose na halitta. Idan aka kwatanta da wasu masu kauri ko adhesives, kamar sitaci, guar danko, da sauransu, farashin methylcellulose yakan fi girma. Saboda haka, a wasu masana'antu ko aikace-aikace masu tsadar gaske, methylcellulose na iya zama ba mai amfani da tsada ba, musamman inda ake samun wasu madadin kayan.
6. Yana iya haifar da rashin lafiyar wasu mutane
Kodayake ana ɗaukar methylcellulose gabaɗaya lafiya kuma ba mai guba ba, ƙaramin adadin mutane na iya samun rashin lafiyarsa. Musamman a cikin magunguna ko filayen kwaskwarima, methylcellulose na iya haifar da rashin lafiyar fata ko wasu mummunan halayen. Wannan babbar hasara ce ga ƙwarewar mai amfani da karɓar samfur. Don haka, ana buƙatar taka tsantsan yayin amfani da methylcellulose a wasu jama'a, kuma ana yin gwajin rashin lafiyar da ya dace.
7. Daidaitawa tare da sauran sinadaran
A cikin abubuwan da aka tsara, methylcellulose na iya samun al'amurran da suka dace tare da wasu wasu sinadaran. Misali, yana iya amsawa tare da wasu gishiri, surfactants ko abubuwan kaushi na halitta, haifar da rashin kwanciyar hankali ko rage aiki. Wannan batun daidaitawa yana iyakance amfani da methylcellulose a cikin wasu hadadden tsari. Bugu da ƙari, methylcellulose na iya nuna hulɗar hana juna tare da wasu masu kauri, mai rikitarwa ƙirar ƙira.
8. Ayyukan jin daɗi a aikace-aikace
A cikin abinci da filayen magunguna, amfani da methylcellulose na iya yin tasiri akan abubuwan ji na samfur. Duk da yake methylcellulose gabaɗaya ba shi da ɗanɗano kuma mara wari, a wasu lokuta yana iya canza salo ko bakin samfur. Misali, methylcellulose na iya ba da daidaito mara dabi'a ko mannewa ga samfuran abinci, wanda bazai dace da tsammanin mabukaci ba. Bugu da kari, aikace-aikacen methylcellulose a cikin wasu samfuran ruwa na iya shafar iya tafiyarsu ko bayyanarsu, ta haka yana shafar karɓuwar mabukaci.
A matsayin abu mai mahimmanci, ana amfani da methylcellulose sosai a fannoni da yawa, amma ba za a iya watsi da gazawarsa da iyakokinta ba. Methylcellulose yana da wasu gazawa dangane da solubility, acid da juriya na alkali, biodegradability, kaddarorin inji, farashi da dacewa tare da sauran sinadaran. Fahimtar da ma'amala da waɗannan gazawar yana da mahimmancin mahimmanci don haɓaka amfani da methylcellulose a aikace-aikace masu amfani.
