Ukwamkela uZinzo: Ukunyuka kwezitywini ezisekelwe emanzini

Kwiminyaka yakutshanje, kukho utshintsho olubalulekileyo olubhekiselele kwiinkqubo ezizinzileyo kuwo wonke amashishini ahlukeneyo, kwaye ishishini lezogquma linjalo. Izitywini ezisekelwe emanzini ziye zavela njengephambili kule ntshukumo, zinika ubuninzi beenzuzo ezijongene nokuxhalabisa kokusingqongileyo kunye neemfuno zokusebenza.

Izitywini ezisekwe emanzini, ezikwaziwa ngokuba zizitywini zasemanzini, zizixube ezisebenzisa amanzi njengezona zithwala zinyibilikisiweyo endaweni yezinyibilikisi zemveli ezifana ne-petroleum distillates okanye ii-volatile organic compounds (VOCs). Ezi zitywini zihlala zine-acrylic okanye i-polyurethane resins ezisasazwe emanzini, kunye nezongezo zokuphucula ukunamathela, ukuqina, kunye nokusebenza.

Enye yeenzuzo eziphambili zezitywini ezisekwe emanzini yimpembelelo yazo encinci yokusingqongileyo. Ngokuqulatha ii-VOC eziphantsi okanye zero, zinegalelo ekuphuculeni umgangatho womoya wangaphakathi kunye nokunciphisa ukukhutshwa okuyingozi, okwenza ukuba zilungele ukusetyenziswa kwiindawo ezinobume bendalo. Oku kuhambelana nendalo kuhambelana nemfuno ekhulayo yezinto zokwakha ezizinzileyo kunye nezenzo.

Olunye uncedo oluphambili lwee-sealers ezisekelwe emanzini kukulula kwabo ukusetyenziswa. Ngokungafaniyo ne-solvent-based sealers, ehlala ifuna izixhobo ezikhethekileyo kunye neenkqubo zokungenisa umoya, izitywini ezisekelwe emanzini zingasetyenziswa kusetyenziswa iibrashi, iiroli, okanye izitshizi, ezivumela ukusetyenziswa ngokufanelekileyo kunye nokungakhathali kwiindawo ezahlukeneyo. Oku kulula kwesicelo akugcini nje ixesha kunye nomsebenzi kodwa kunciphisa ukuchanabeka kwiikhemikhali ezinobungozi, ukomeleza ukhuseleko lwabasebenzi.

Ukongeza kwiinzuzo zabo zokusingqongileyo kunye nezinto eziphathekayo, abatywini bamanzi banikezela ngeempawu ezintle zokusebenza. Babonelela ngokhuseleko oluhlala ixesha elide ngokuchasene nokufuma, imitha ye-UV, kunye nemozulu, ibenza bafanelekele usetyenziso lwangaphakathi nangaphandle. Amaxesha abo okoma okukhawulezayo avumela ukuguqulwa okukhawulezileyo kunye nexesha elincinci lokuphumla, lizenza zilungele iiprojekthi ezinexesha elisikiweyo okanye apho kufuneka iidyasi ezininzi.

Izitywini ezisekelwe emanzini nazo zisebenza ngeendlela ezininzi, zilungele uluhlu olubanzi lwee-substrates, kuquka ikhonkrithi, umthi, ilitye, kunye ne-masonry. Nokuba kukutywina i-driveway, ukukhusela ipatio, okanye ukuphucula inkangeleko yemigangatho yangaphakathi, izitywini ezisekwe emanzini zibonelela ngezisombululo eziguquguqukayo kwizicelo ezahlukeneyo.

Ukuqukumbela, izitywini ezisekelwe emanzini zimela isisombululo esizinzileyo nesisebenzayo sokukhusela kunye nokuphucula iindawo ezahlukeneyo. Ngempembelelo yabo encinci yokusingqongileyo, ukusetyenziswa lula, ixesha lokumisa ngokukhawuleza, kunye nokusetyenziswa kwezinto eziguquguqukayo, ama-sealer-based sealers avula indlela yekamva eliluhlaza kunye nelozinzo kwishishini leengubo. Ngokwamkela ezi ngubo zokwaleka zintsha, sinokwakha ihlabathi eliqaqambileyo nelizinzileyo kwizizukulwana ezizayo.

Ukuba unemibuzo ethile okanye iimfuno ezingaphezulu malunga nekhonkrithi enemibala, unakothetha nathi.
