Kuchapa chowonjezera cha methyl hydroxethyl cellulose machec

Methyl hydrothyl cellulose (mahec) ndiowonjezera omwe amagwiritsidwa ntchito pochapira zovala. Ndi ya banja la cellulose etrai, lomwe limachokera ku cellulose. Mithc imapangidwa ndi cellulose ndi methyl chloride ndi ethylene oxide, chifukwa chophatikizira pamodzi ndi mitundu yonse ya methyl ndi hydroxyathyl fupa lam'madzi.

Chimodzi mwazinthu zofunikira za mico omwe zimapangitsa kuti zikhale zofunikira kuchapa ndi kuthekera kwake kuchita ngati chindapusa komanso kukhazikika. M'malo opindika, mahec amathandizira kuti mamasukidwe a chinthucho, amalepheretsa kukhala ochepa kwambiri kapena amadzi. Izi zikuwonetsetsa kuti chotchinga chimasanthula zomwe mukufuna kusungiramo ndikugwiritsa ntchito.

Mhec amakhala ngati colloid colloid, akuthandizira kukhazikitsa zotchinga zina ndi zoletsa ndikuwalepheretsa kulekanitsa kapena kusungunuka. Izi ndizofunikira makamaka pakupanga zokhala ndi zigawo kapena zopangidwa, chifukwa mathec amathandizira kuti izi zisasokonekere.

Mic imawonjezera mapangidwe ochapira pochapira powonjezera kuthekera kwawo konyowa ndikulowa nsalu. Kukhalapo kwake mu mawonekedwe kumathandiza kuti otchipa afalikire pomwepo kudutsa nsalu, kuwunikira kuyeretsa kwathunthu.

Phindu lina la Ahec ndi kugwirizana kwake ndi zosakaniza zina zomwe zimapezeka m'malo ena ochapira, kuphatikizapo okonda, ma enzymes, komanso owoneka bwino. Kusintha kumeneku kumapangitsa kuti mathec ndi owonjezera owonjezera a clandular, monga momwe ingagwiritsidwire ntchito mitundu yosiyanasiyana ya zotchinga zotchinga popanda kusintha.

Mhec ndi biodegrad chilengedwe komanso wochezeka, ndikupangitsa kuti azisankha opanga omwe akufuna kupanga zinthu zopatsirana. Kusintha kwake kuphiri kumatsimikizira kuti kumasweka mosavuta mu dongosolo la madzi amoto, kuchepetsa mphamvu zachilengedwe.

Methyl hydrothyl cellulose (mahec) ndiowonjezera owonjezera omwe amapereka maubwino angapo kuti apindule zovala. Kutha kwake kumakula, kukhazikika, ndikusintha mapangidwe opanga kumapangitsa kuti zikhale zofunikira kwa opanga omwe akufuna kupanga zovala zopambana komanso zopatsa thanzi.
