Bambanci tsakanin hydroxypropyl sitaci ether da cellulose ether

Yanzu mutane da yawa ba su sani ba game da sitaci na hydroxypropyl ether.Suna tunanin cewa akwai ɗan bambanci tsakanin hydroxypropyl sitaci ether da talakawa sitaci, amma ba haka ba.Adadin hydroxypropyl sitaci ether da aka yi amfani da shi a cikin samfuran turmi kaɗan ne, kuma adadin adadin polar zai iya samun sakamako mai kyau.

Hydroxypropyl sitaci ether (HPS) fari ne mai kyau foda da aka samu ta hanyar gyaggyarawa shuke-shuken halitta, wanda aka fidda shi sosai, sannan a fesa-bushe, ba tare da robobi ba.Ya bambanta da sitaci na yau da kullun ko sitaci da aka gyara.

Kuma hydroxypropyl methyl cellulose, wanda kuma aka sani da hypromellose, hydroxypropyl methyl ja bitamin ether, shi ne a yi amfani da sosai tsarki auduga cellulose a matsayin danye, da kuma bi da shi da lemun tsami a 35-40 ° C na rabin sa'a, Matsi, murkushe cellulose, da kuma shekaru daidai a 35 ° C, don haka matsakaicin digiri na polymerization na fiber alkali da aka samu yana cikin kewayon da ake buƙata.Saka alkali fiber a cikin kettle etherification, ƙara propylene oxide da methyl chloride a jere, da kuma etherify shi a 50-80 ° C na 5 hours, kuma matsakaicin matsa lamba ne game da 1.8MPa.Sa'an nan kuma ƙara yawan adadin hydrochloric acid da oxalic acid a cikin ruwan zafi a 90 ° C don wanke kayan don faɗaɗa ƙarar, sa'an nan kuma zubar da shi tare da centrifuge, kuma a karshe wanke shi akai-akai zuwa tsaka tsaki.Ana amfani da shi sosai a cikin gine-gine, masana'antar sinadarai, fenti, likitanci, masana'antar soja da sauran fannoni, bi da bi a matsayin wakili mai shirya fim, ɗaure, watsawa, stabilizer, thickener, da sauransu.

Hydroxypropyl sitaci ether za a iya amfani da matsayin admixture ga tushen siminti kayayyakin, gypsum tushen kayayyakin da lemun tsami kayayyakin.Yana da kyakkyawar dacewa tare da sauran abubuwan haɗin ginin.Amfani tare da hydroxypropyl methylcellulose ether HPMC, zai iya rage sashi na hydroxypropyl methylcellulose (yawanci ƙara 0.05% na HPS iya rage sashi na HPMC da game da 20% -30%), kuma zai iya taka wani thickening sakamako , don inganta ciki. tsari, tare da mafi kyawun juriya da ingantaccen aiki.
