Ineempawu ezintle kakhulu zefilimu kunye ne-rheological adjustment, enokuqinisekisa ukuba i-coating inokusasazwa kakuhle phantsi kwezixhobo ezahlukeneyo zokwakha. Ukongeza, i-ether ye-cellulose inokuphucula ipropathi echasayo yokwaleka, iyenze ukuba inganciphisi ukugoba xa isetyenziswa kwindawo ethe nkqo, ngaloo ndlela ifumana isambatho esifanayo.
Izincamathelisi zethayile
I-adhesives ye-tile sisicelo esibalulekileyo kwintsimi yezinto zokwakha ezihambelana nokusingqongileyo. I-cellulose ethers inokuphucula ngokufanelekileyo ukugcinwa kwamanzi kunye ne-anti-slip properties ze-adhesives kunye nokuphucula amandla okudibanisa phakathi kweetayile kunye nomgangatho wesiseko. Ngethuba lokwakha, ukongezwa kwe-cellulose ethers kuphucula kakhulu ukusebenza kwe-adhesives tile, ngelixa kuqinisekisa ixesha elide elivulekileyo, elilungele abasebenzi bokwakha ukuba balungelelanise.
Umgubo weputty
I-putty powder isetyenziselwa ukulinganisa udonga kunye nokulungiswa. Ukugcinwa kwamanzi kwe-cellulose ether kunokuthintela ukuqhekeka okanye ukuwa okubangelwa ukomisa kwe-putty ngokukhawuleza emva kokwakhiwa. Ngelo xesha, ipropathi yayo yokuqina inceda ekuphuculeni i-coating kunye ne-putty egudileyo, okwenza ulwakhiwo lube lula.
Izinto zomgangatho ozimele
Ukusetyenziswa kwe-cellulose ether kwizixhobo zomgangatho wokuzimela ngokuzimeleyo kukuphucula i-fluidity kunye nokugcinwa kwamanzi, ukuqinisekisa ukuba izinto eziphathekayo ziyakwazi ukukhawuleza kwaye zisasazwe ngokulinganayo ngexesha lokwakhiwa komhlaba, kunye nokuthintela umgangatho wokuqhekeka okanye ukuthungwa kwehlabathi okubangelwa ukulahlekelwa kwamanzi.
