Admixtimes amatenga mbali yofunika kwambiri pakuwongolera matope osakanikirana. Kusanthula kotsatiraku ndikufanizira zinthu zoyambira ma cellxr ndi cellulose, ndikusanthula matope owuma owuma pogwiritsa ntchito ma addictures.
Kubwezeretsedwanso
Ufa wosinthidwa mochedwaxr umakonzedwa ndi kupukuta kwa emulsion yapadera. Ufa wowuma ndi ufa ndi tinthu tambiri za 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. Mafuta aposachedwa ogwiritsira 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:
. zomanga.
.
fiber
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:
.
.
. Koma ilibe madzi ambiri a ether.
