Zotsatira za Farax ufa ndi cellulose pa matope owuma

Admixtimes amatenga mbali yofunika kwambiri pakuwongolera matope osakanikirana. Kusanthula kotsatiraku ndikufanizira zofunikira za matex ufa ndi cellulose, ndikusanthula magetsi owuma pogwiritsa ntchito matope owuma.

Kubwezeretsedwanso

Kubwezeretsedwansoimakonzedwa ndi kupukuta kwa polima kwa polima. Ufa wowuma watedx ndi tinthu ena ozungulira 80 ~ 100mm asonkhana palimodzi. Tinthu toyambitsa timasungunuka m'madzi ndikupanga zotupa zokulirapo pang'ono kuposa gawo loyambirira la emulsion, lomwe limapanga filimu pambuyo pakuwuma ndi kuyanika.

Njira zosinthira zosiyanasiyana zimapangitsa kuti ufa wokwezedwa ukhale ndi malo osiyanasiyana monga kukana madzi, alkali akukana, kukana nyengo komanso kusinthasintha. Masamba a Matope Ogwiritsa ntchito matope amatha kusintha kukana, kulimba, kuvala mphamvu, kukana mphamvu, kuwononga mphamvu ndi kuthekera kwa matope.

Cellulose ether

Cellulose ether ndi mawu angapo kuti mupange zinthu zingapo zomwe zimapangidwa ndi alkali cellulose ndikumupeza wothandizika pazinthu zina. Ma cellulose amasinthidwa ndi othandizira osiyanasiyana kuti apeze cellulose yosiyanasiyana. Malinga ndi ma ionization katundu wa magalimoto, cellulose edel amatha kugawidwa m'magulu awiri: Ionic (monga carboxymethyl cellulose). Malinga ndi mtundu wa gawo lamitundu yamitundu itha kugawidwa mu monoether (monga methyl cellulose) ndi ethersed ether (monga hydroxypropyl celyiluse). Malinga ndi kusungunuka kosiyanasiyana, imatha kugawidwa m'madzi (monga hydrothyl cellulose) ndi matope osungunuka ndi ethyl cellulose.

Limagwirira ku zochita za cellulose ether mu matope ndi motere:

(1) Pambuyocellulose etherMu matope amasungunuka m'madzi, kugawa ndi yunifolomu ndi valone komwe kumatsimikiziridwa chifukwa cha matope okhazikika, komanso amasintha madzi otchinga, komanso bwino kwambiri.

Phazi lotchi limapangidwa ndi zomera ngati zopangira zazikulu ndikukonzedwa ndi magulu angapo a teminoloje, ndipo magwiridwe ake ndi osiyana ndi a cellulose. Malo akulu ndi awa:
