Methylcellulose

Methylcellulose bụ ụdị ether cellulose nke a na-ejikarị eme ihe n'ụlọ ọrụ dị iche iche maka ihe na-eme ka ọ sie ike, na-eme ka ọ dị ike, na-emepụta ihe nkiri. A na-enweta ya site na cellulose, nke bụ isi ihe nhazi nke mgbidi cell osisi. A na-emepụta Methylcellulose site n'ịgwọ cellulose na methyl chloride ma ọ bụ dimethyl sulfate iji webata otu methyl na molekul cellulose. Nke a bụ isi ihe ụfọdụ gbasara methylcellulose:

1. Ọdịdị kemịkalụ:

• Methylcellulose na-ejigide usoro cellulose bụ isi, nke mejupụtara nkeji glucose ugboro ugboro jikọtara ọnụ site na β(1→4) glycosidic bonds.
• A na-ewebata otu methyl (-CH3) na otu hydroxyl (-OH) nke mkpụrụ ndụ cellulose site na mmeghachi omume etherification.

2. Ngwongwo:

• Solubility: Methylcellulose bụ soluble na mmiri oyi ma mepụta ngwọta doro anya, viscous. Ọ na-egosipụta omume gelation thermal, nke pụtara na ọ na-etolite gel na oke okpomọkụ wee laghachi na ngwọta mgbe jụrụ oyi.
• Rheology: Methylcellulose na-arụ ọrụ dị ka onye na-esi ísì ụtọ, na-enye njikwa viscosity na nkwụsi ike na nhazi mmiri. Ọ nwekwara ike gbanwee omume ịgbasa na udidi nke ngwaahịa.
• Ịme ihe nkiri: Methylcellulose nwere ihe na-emepụta ihe nkiri, na-enye ya ohere ịmepụta ihe nkiri dị nro ma na-agbanwe agbanwe mgbe akpọnwụwo. Nke a na-eme ka ọ baa uru na mkpuchi, adhesives, na mbadamba ọgwụ.
• Nkwụsi ike: Methylcellulose kwụsiri ike n'ọtụtụ pH na ọnọdụ okpomọkụ, na-eme ka ọ dị mma maka ojiji n'ụdị dị iche iche.

3. Ngwa:

• Nri na ihe ọ beụ beụ: A na-eji ya dị ka ihe na-ekpu, stabilizer, na emulsifier na ngwaahịa nri dị ka sauces, ofe, desserts, na mmiri ara ehi ndị ọzọ. Enwere ike iji ya kwalite nhazi na ọnụ nke ngwaahịa nri.
• Pharmaceuticals: A na-arụrụ ya ọrụ dị ka onye na-ekekọta, na-ekesa, na onye ntọhapụ na-achịkwa na mbadamba ọgwụ na capsules. A na-eji usoro methylcellulose eme ihe maka ike ha ịnye ntọhapụ ọgwụ otu na imeziwanye nnabata onye ọrịa.
• Nlekọta onwe onye na ihe ịchọ mma: A na-eji ya dị ka ihe na-agba agba, ihe nkwụsi ike na ihe nkiri bụbu na ude, ude, shampoos, na ngwaahịa nlekọta onwe onye ndị ọzọ. Methylcellulose na-enyere aka ịkwalite viscosity ngwaahịa, udidi na nkwụsi ike.
• Ihe owuwu: A na-eji ya dị ka onye na-agbapụta mmiri, onye na-ejigide mmiri, na rheology modifier na ngwaahịa simenti, agba, mkpuchi, na nrapado. Methylcellulose na-eme ka arụ ọrụ, nrapanye, na imepụta ihe nkiri na ihe owuwu ihe.

4. Nkwado:

• A na-enweta Methylcellulose site na isi mmalite sitere na ihe ọkụkụ, na-eme ka ọ bụrụ enyi na gburugburu ebe obibi ma na-adigide.
• Ọ bụ ihe na-emebi emebi, ọ naghị etinye aka na mmetọ gburugburu ebe obibi.

Mmechi:

Methylcellulose bụ polymer na-adịgide adịgide yana ọtụtụ ngwa na nri, ọgwụ, nlekọta onwe onye, ​​na ụlọ ọrụ ihe owuwu. Ngwongwo ya pụrụ iche na-eme ka ọ bụrụ ihe dị mkpa n'ọtụtụ nhazi, na-enye aka na arụmọrụ ngwaahịa, nkwụsi ike, na ịdị mma. Ka ụlọ ọrụ na-aga n'ihu na-ebute nkwado nkwado na ngwọta enyi na enyi, a na-atụ anya na ọchịchọ methylcellulose ga-eto eto, na-ebugharị ihe ọhụrụ na mmepe na mpaghara a.
