3. Phucula ukuxhathisa ukunyibilika komkhenkce
I-cellulose ethers yonyusa ukuxinana kodaka, iyenza ikwazi ukumelana nemijikelo yokunyibilika komkhenkce. Oku kuxhathisa i-freeze-thaw kubaluleke kakhulu kwiidaka ezisetyenziselwa kwiindawo ezibandayo, ezinokwandisa ngokufanelekileyo ubomi benkonzo yesakhiwo kunye nokunciphisa iindleko zokugcinwa.
(3) Ukuphucula ukuguquguquka kokusingqongileyo kulwakhiwo
1. Yandisa iiyure zokuvula
I-cellulose ethers inokwandisa ixesha lokuvula udaka, oko kukuthi, ixesha lodaka oluhlala lusebenza emva kokuba lubekwe. Oku kunenzuzo ngokukhethekileyo ekwakhiweni kwiqondo lokushisa eliphezulu okanye kwiindawo ezomileyo, ukunciphisa ingxaki yokuqina kwangaphambili kodaka oluchaphazela umgangatho wokwakha.
2. Ukuphucula ukuxhathisa kwe-sag
Xa kusakhiwa kumphezulu othe nkqo, udaka luthanda ukutyibilika okanye ukuhexa. I-ether ye-Cellulose iphucula ukusebenza kwe-anti-sag yodaka ngokujiya, iqinisekisa ukuba udaka lunokugcinwa ngokuzinzileyo kwiindawo ezithe nkqo kunye nokuphepha iziphene zokwakha.
(4) Iinzuzo zendalo nezoqoqosho
1. Ukuphucula ukusetyenziswa kwezinto
I-ether ye-cellulose inokuphucula kakhulu ukusebenza kunye nomgangatho wokwakhiwa kodaka, kunye nokunciphisa inkunkuma yezinto eziphathekayo ngexesha lokwakha. Oku kunokubaluleka koqoqosho olubalulekileyo kulwakhiwo olukhulu kwiiprojekthi zokwakha, ezinokunciphisa iindleko zempahla kunye nokuphucula inzuzo yezoqoqosho yokwakha.
2. Ayinabungozi kokusingqongileyo
I-cellulose ethers zizinto ezisekelwe kwi-bio kwaye zinempembelelo encinci kwindalo ngexesha lokuvelisa kunye nokusetyenziswa kwazo. Ukongeza, inokunciphisa ngokufanelekileyo ungcoliseko lwesibini ngexesha lokwakhiwa kodaka, njengothuli kunye nenkunkuma, kwaye ihlangabezana neemfuno zezakhiwo zanamhlanje eziluhlaza.
(5) Imizekelo yokusetyenziswa ngokuthe ngqo
1. I-adhesive ye-tile
Kwii-adhesive tile ze-ceramic, ukongezwa kwe-cellulose ether kunokuphucula kakhulu ukusebenza, ukugcinwa kwamanzi kunye nokuqina kokubambisana kwe-adhesive, kunye nokuphucula umphumo wokudibanisa kunye nokusebenza kakuhle kokwakhiwa kweetayile ze-ceramic.
