Menene Cellulose Ethers kuma Me yasa Ake Amfani da su?

Cellulose ethers sune polymers masu narkewa da ruwa wanda aka yi daga cellulose, babban tsarin tsarin shuke-shuke. Akwai nau'ikan ethers na cellulose da yawa, kowannensu yana da kaddarorin na musamman waɗanda ke sa su dace don aikace-aikace iri-iri.

Ana amfani da maki na fasaha na ethers cellulose a cikin komai daga magunguna da kayan shafawa zuwa gini da masana'anta. Bugu da ƙari, ana amfani da su azaman ƙari na abinci da masu kauri a cikin fenti da sutura.

Nau'in ethers cellulose

Mafi yawan nau'ikan ethers cellulose guda uku sune hydroxypropylmethylcellulose (HPMC), methylhydroxyethylcellulose (MHEC).

Saboda iyawar sa, HPMC ita ce nau'in ether ɗin cellulose da aka fi amfani dashi. Ana samunsa a nau'o'i daban-daban tare da ma'auni daban-daban na kwayoyin halitta, digiri na maye gurbin da danko. Ana iya amfani da HPMC a duka maganin acidic da alkaline, yana mai da shi manufa don aikace-aikace da yawa.

MHEC yayi kama da HPMC amma yana da ƙananan abun ciki na hydroxypropyl. Idan aka kwatanta da HPMC, zafin jiki na gelation na MHEC yawanci ya fi 80 ° C, dangane da abun ciki na rukuni da hanyar samarwa. MHEC ana yawan amfani dashi azaman mai kauri, ɗaure, emulsion stabilizer ko tsohon fim.

Cellulose ethers suna da amfani da yawa saboda abubuwan da suke da su na musamman. Wasu amfani na yau da kullun na ethers cellulose sun haɗa da:

Masu kauri: Ana iya amfani da ethers na cellulose azaman masu kauri don masu mai, adhesives, sinadarai na filin mai, abinci, kayan kwalliya, da magunguna.

Masu ɗaure: Ana iya amfani da ethers cellulose azaman masu ɗaure a cikin allunan ko granules. Suna inganta damfara na foda yayin da har yanzu suna riƙe da kyawawan kaddarorin kwarara.

Emulsion Stabilizers: Cellulose ethers na iya daidaita emulsions ta hana coalescence ko flocculation na tarwatsa lokaci droplets. Wannan ya sa su dace don amfani da su a cikin emulsion polymers kamar fentin latex ko adhesives.

Tsoffin Fim: Ana iya amfani da ethers na Cellulose don samar da fina-finai ko sutura a saman. Ana amfani da su sau da yawa a aikace-aikacen gini kamar tayal ko adhesives na fuskar bangon waya. Fina-finan da aka yi daga ethers cellulose yawanci a bayyane suke kuma masu sassauƙa, tare da juriya mai kyau.
