Oku kubaluleke ngakumbi kwiindawo ezifumileyo ezifana namagumbi okuhlambela kunye namakhitshi, apho amanqanaba okufuma aphezulu.
1.5 Ukwakhiwa kunye neeyure zokuvula:
Iimpawu ze-rheological ze-polymers eziphinda zenziwe kwakhona zidlala indima ebalulekileyo ekusebenzeni kwe-adhesives tile. Banceda ukugcina ukuhambelana okufanelekileyo kunye nokuqinisekisa ukusetyenziswa okulula. Ukongeza, i-polymer ephinda ihlaziywe inceda ukwandisa ixesha elivulekileyo lokuncamathelisa, inika abafakeli ixesha elaneleyo lokulungelelanisa indawo yethayile phambi kweeseti zokuncamathelisa.
2. ISelulosi:
2.1 Inkcazo kunye neendidi:
I-Cellulose yipolymer yendalo ephuma kwiindonga zeeseli zezityalo kwaye isoloko isetyenziswa njengesongezo kwi-adhesives tile. I-cellulose ethers, efana ne-methylcellulose (MC) kunye ne-hydroxyethylcellulose (HEC), isetyenziswa rhoqo ngenxa yokugcinwa kwamanzi okugqwesileyo kunye neempawu zokuqina.
2.2 Ukugcinwa kwamanzi:
Omnye wemisebenzi ephambili ye-cellulose kwi-adhesives ye-tile kukukwazi ukugcina amanzi. Olu phawu lwandisa ixesha elivulekileyo lokuncamathelisa, ngaloo ndlela ukwandisa ukuqhubekeka. Xa i-cellulose ithatha amanzi, yenza i-gel-efana nesakhiwo esithintela i-adhesive ukuba yome ngokukhawuleza ngexesha lokusetyenziswa.
2.3 Phucula ukuqhubekeka kunye nokumelana ne-sag:
I-Cellulose iphucula ukusebenza kwe-adhesive ye-tile ngokuthintela ukugoba ngexesha lokusetyenziswa ngokuthe nkqo. Umphumo wokuqina we-cellulose unceda i-adhesive igcine imilo yayo eludongeni, iqinisekisa ukuba iileyili zihambelana ngokulinganayo ngaphandle kokuwa.
2.4 Nciphisa ukushwabana:
I-Cellulose inokunciphisa i-shrinkage ye-adhesive tile ngexesha lokumisa. Oku kubaluleke kakhulu kuba ukucutheka okugqithisileyo kunokukhokelela ekwenziweni kwe-voids kunye nokuqhekeka, ukuphazamisa ingqibelelo yonke yebhondi.
2.5 Impembelelo kumandla okuqina:
Izinto zokuncamathelisa iithayile zineselulosi ukunyusa amandla azo okuqina. Oku kubaluleke kakhulu kwiindawo eziphantsi kwemithwalo enzima okanye uxinzelelo, njengoko igalelo ekuhlala kuyo yonke into kunye nokusebenza komphezulu we-tile.
3. Impembelelo ye-Synergistic ye-polymer ephinda ihlakazwe kunye neselulosi:
3.1 Ukuhambelana:
Iipolymers ezihlaziywayo kunye ne-cellulose zihlala zikhethwa ngokuhambelana kwazo kunye nezinye izithako ekubunjweni kwe-adhesive tile. Oku kuhambelana kuqinisekisa umxube we-homogeneous owandisa iinzuzo zesongezo ngasinye.
3.2 Indibaniselwano yentsebenziswano:
Ukudibanisa i-polymer ephindwe kabini kunye ne-cellulose ivelisa umphumo we-synergistic kwi-bonding. Iifilimu eziguquguqukayo ezenziwe kwi-polymers eziphinda ziphinde zenziwe zincedisana nokugcinwa kwamanzi kunye neempawu ezityebisayo ze-cellulose, ezikhokelela kwi-adhesive eyomeleleyo, ehlala ixesha elide kunye nesebenzayo.
3.3 Ukusebenza okuphuculweyo:
I-polymer edibeneyo kunye ne-cellulose edibeneyo iphucula ukusebenza ngokubanzi kwe-adhesive tile, inikezela ukunamathela okungcono, ukuguquguquka, ukuchasana kwamanzi, ukuqhutyelwa phambili kunye nokuqina. Olu luhlu lunenzuzo ngakumbi kwaye luyimfuneko kwizicelo ezifuna ukuxhamla okuthembekileyo kunye nexesha elide.
Ukubandakanya iipolymers eziphinda zihlakazwe kunye neselulosi kwi-adhesives ye-tile yinkqubo ecwangcisiweyo kunye neqinisekisiweyo kwishishini lokwakha. Ezi zongezo zidlala indima ephambili ekwandiseni ukubambelela, ukuguquguquka, ukuxhathisa kwamanzi, ukuqhubekeka kunye nokuqina kwexesha elide. I-synergy phakathi kweepolymers eziphinda zihlakazwe kunye ne-cellulose iphumela kwi-balanced adhesive formulations ehlangabezana neemfuno ezifunekayo zeeprojekthi zokwakha zanamhlanje. Njengoko iteknoloji kunye nophando luqhubeka luqhubela phambili, ezinye izinto ezintsha kwindawo yokubambelela kwi-tile kulindeleke ukuba zenzeke, ngokugxininisa ngokuqhubekayo ekuphuculeni ukusebenza kunye nokuzinza kwezi zixhobo zokwakha ezibalulekileyo.
