Uhlahlelo lweMigaqo yokutywina kunye nokuSetyenziswa kocango kunye nesitywina sefestile

Njengomsebenzi obalulekileyo osebenzayo kushishino lokwakha, ucango kunye nefestile ye-sealants 'umsebenzi ongundoqo kukufezekisa ukutywinwa, ukuvalwa kwamanzi, kunye nokungabikho komoya kwiindawo ezihlangeneyo ngokuphendula ngokomzimba kunye neekhemikhali. Umgaqo wabo wokusebenza usekelwe ngokukodwa kwimpembelelo ye-synergistic yezinto eziphathekayo kunye noyilo lwesakhiwo.

 

Ngokwenyama, izinto zokutywina zilulwelo okanye zincamathelise-njengaphambi kokuba zinyange, zizalise ngokupheleleyo izithuba ezincinci (eqhelekile ukuba yi-3-}20mm) phakathi kocango kunye neefreyimu zefestile kunye nodonga neglasi, zenza umzimba onwebekayo oqhubekayo. Emva kokunyanga, imathiriyeli iphuhlisa -ulwakhiwo oludityanisiweyo, lunika ukomelela okuhlala ixesha elide kunye nokulungelelaniswa nokufuduswa kwamalungu okubangelwa kukuguquguquka kwamaqondo obushushu (± 30 degree), ukuguquguquka kokufuma, kunye noxinzelelo lomoya (umthamo wokufuduswa udlula i-25%). Olu tshintsho lwe-elastic luqinisekisa uqhagamshelwano olungaguqukiyo phakathi kwe-interface yokutywina kwaye luthintela iindlela zokungena emoyeni kunye namanzi angamanzi.

Indlela yokutywinwa kweekhemikhali ixhomekeke kuyilo lokuqulunqa izinto. Izitywini zeSilicone zifezekisa ukuxhathisa kwemozulu ngokusebenzisa amandla ebhondi aphezulu e-Si{1}}iibhondi ze-O (malunga ne-452 kJ/mol). Amandla abo aphantsi komhlaba (malunga ne-20-24 mN/m) agxotha iimolekyuli zamanzi kwaye axhathise ukuguga kwe-UV. Ii-polyurethane sealants, kwelinye icala, zisabela ngokufuma emoyeni zenze iibhondi ze-urea zisebenzisa amaqela e-isocyanate, zenza uthungelwano oluqinileyo{7}}isakhiwo sothungelwano esibhetyebhetye esibonelela ngokuphezulu{9}}ibhondi yamandla ngelixa igcina ukuthamba okuphakathi. Ezinye iimveliso ezikumgangatho ophezulu zikwabandakanya izihluzi ze-hydrophobic (ezifana ne-silica) okanye ii-antimicrobial agents ukuqhubela phambili ukuqina.

Iifestile zala maxesha kunye nezitywini zomnyango kufuneka zihlangabezane neemfuno zokusingqongileyo, kunye neefomyula ezisezantsi-zeVOC (i-volatile organic compound) zibe zezona ziqhelekileyo. Ukukhetha i-sealant efanelekileyo kufuna ukuqwalaselwa ngokubanzi kohlobo lwe-substrate (umzekelo, i-aluminium alloy, i-PVC), indawo yokusebenza (iindawo ezifumileyo / ezomileyo), kunye neemeko zokulayisha ngoomatshini. Ukusebenza kokutywina kuphunyezwa ngenkqubo yesicelo sobuchule (umzekelo,{7}}isitofu sompu esinye okanye ezimbini{8}}ezixutywayo).
