Izinamathiselo zamathayela zidlala indima ebalulekile ekwakhiweni kwesimanje, ukuhlinzeka ukunamathela okuqinile kanye nokuguquguquka kwezicelo zamathayili ahlukahlukene. Esinye sezithasiselo ezibalulekile ezisetshenziswa ekwenziweni kwe-adhesive adhesive isI-Hydroxyethyl Methyl Cellulose (HEMC), i-cellulose ether eyaziwa ngamandla ayo okuthuthukisa ukusebenza ngokushintsha izici zokunamathisela ezinamathelayo nezisebenzayo.
Izakhiwo ze-Hydroxyethyl Methyl Cellulose (HEMC)
I-HEMC iyi-polymer engeyona i-ionic, encibilika emanzini etholakala ku-cellulose. Isetshenziswa kabanzi ezintweni zokwakha ngenxa yayoukuqina, ukugcinwa kwamanzi, kanye nezakhiwo zefilimu. Ezinamathiselwe zamathayela, i-KimaCell®HEMC isebenza njenge-ai-rheology modifier, ukuthuthukisa ukusebenza kohlelo lokusebenza jikelele.
Izici ezibalulekile ze-HEMC:
- Ukugcinwa kwamanzi:Ivimbela ukomiswa ngaphambi kwesikhathi, iqinisekisa ukugeleza okufanele kukasimende.
- I-ejenti yokuqina:Ithuthukisa ukungaguquguquki nokusebenza.
- Ithuthukisa ukunamathela:Khulisa amandla okubopha phakathi kwamathayili nama-substrates.
- Yandisa isikhathi sokuvula:Ivumela ukusebenza okude kokubekwa kwethayela.

Imithelela ye-HEMC ekusebenzeni kwe-Tile Adhesive
1. Ukuthuthukiswa Kokugcina Amanzi
Ukugcinwa kwamanzi kuyisici esibalulekile ekusebenzeni okunamathelayo kwethayela, ikakhulukazi ezintweni ezinamathelayo ezisekelwe usimende. I-HEMC ithuthukisa kakhulu ukugcinwa kwamanzi, inciphisa izinga lokuhwamuka futhi iqinisekise ukufakwa kwe-cement okwanele. Lokhu kunenzuzo ikakhulukazi ezimweni ezishisayo nezomile, ukuvimbela ukwehluleka kokunamathela ngenxa yokomiswa ngaphambi kwesikhathi.
2. Ukusebenza Okuthuthukisiwe Nokungaguquguquki
Ukwengezwa kwe-HEMC kuthuthukisa izakhiwo ze-rheological ze-adhesive tile, okwenza kube lula ukuxuba, ukusabalalisa, nokuphatha. Ngokulawula i-viscosity, i-HEMC ivimbela ukuhlehla ezinhlelweni eziqondile, okuvumela amathayili ukuthi ahlale endaweni ngaphandle kokushelela. Lokhu kubaluleke kakhulu kumaphrojekthi othayela odongeni.
3. Amandla Okunamathela Akhulisiwe
I-HEMC ithuthukisa amandla okubopha phakathi kwamathayili nama-substrates ngokuthuthukisa ukugeleza kwamanzi okungcono kwezinto zikasimende. I-hydration efanele iqinisekisa ukuthuthukiswa kwe-matrix eqinile, okuholela ekusebenzeni okuthuthukisiwe kokunamathela. Lokhu kubangela ukuncishiswa kwe-tile kanye nokuqina okungcono kwesistimu yokufaka amathayela.
4. Isikhathi Sokuvula Esandisiwe
Isikhathi sokuvula sibhekisela esikhathini lapho amathayela angalungiswa khona ngemva kokufaka okunamathelayo. I-KimaCell®HEMC yelula isikhathi esivulekile ngokunciphisa ukuhwamuka kwamanzi. Lokhu kunikeza ukuguquguquka phakathi nokufakwa, kunciphisa amathuba okuba amathayela ahlehle ngenxa yokubekwa okungafanele.
5. I-Slump Resistance
Kuzinhlelo zokusebenza zamathayili aqondile, ukumelana nokuwohloka kubalulekile ukuvikela amathayela ukuthi angasheleli ngaphambi kokusetha. I-HEMC ikhulisa i-viscosity ye-adhesive, iqinisekisa ukuthi amathayili ahlala ekhona ngemva kokufaka isicelo. Lesi sakhiwo sizuzisa kakhulu kumathayela anefomethi enkulu kanye nezicelo zamatshe asindayo.
6. Ukuzinza Kwe-Freeze-Thaw Okuthuthukisiwe
Izinamathiselo zamathayela eziqukethe i-HEMC zibonisa ukumelana okuthuthukisiwe emijikelezweni yokuncibilika kweqhwa. I-polymer isiza ukugcina ubuqotho bokunamathela ekushiseni okuguquguqukayo, ukuvimbela ukuqhekeka nokwehluleka ngenxa yokwanda nokunciphisa okushisayo.
I-HEMCiyisengezo esibalulekile ekwakhekeni kwe-adhesive adhesive, ethuthukisa ukusebenza ngezindlela eziningi. Ikhono layo lokugcina amanzi, uthuthukise ukusebenza kahle, uqinise ukunamathela, futhi welule isikhathi esivulekilekwenza kube semqoka ezinhlelweni zokusebenza zamathayela zamanje. Ngokuthuthukisa ukugxila kwe-KimaCell®HEMC kokunamathela kuthayela, abakhiqizi bangakwazi ukuthola imikhiqizo yekhwalithi ephezulu eqinisekisa ukuqina, ukusebenziseka kalula, nokusebenza okuthuthukisiwe kokubopha. Intuthuko yesikhathi esizayo kubuchwepheshe be-cellulose ether ingase ithuthukise kakhulu indima yayo ekunamatheleni okwakha, yenze ukufaka amathayela kusebenze kahle futhi kuthembeke.
