Ii-Sealants njengoMda wokuQala woKhuselo ngokuchasene nokonakala kwaManzi kwiZakhiwo

Ukonakaliswa kwamanzi ngomnye wemiba enexabiso elikhulu kunye netshabalalisayo ejongene nezakhiwo zazo zonke iindidi, ukusuka kwizindlu ezincinci zokuhlala ukuya kwizakhiwo ezinkulu zentengiso-ezinkulu kunye nezibonelelo zemizi-mveliso. Ukushiywa kungalungiswanga nangethuba elifutshane, ukungena kwamanzi kunokukhokelela ngokukhawuleza ekuwohlokeni okukhulu kwesakhiwo, ukukhula komngundo okunetyhefu, kunye nokulungiswa kwexabiso eliphezulu okungagcini nje ukubeka esichengeni ukhuseleko kunye nokuphila ixesha elide kwesakhiwo kodwa kuphazamise ubomi bemihla ngemihla yabahlali okanye imisebenzi yamashishini. Apha kulapho{3}izitywini zodidi oluphezulu zolwakhiwo zidlala indima ebalulekileyo engenakuphinda zibuyiselwe{4}}njengomgca wokuqala wokhuselo ekungeneni kwamanzi, zidala umqobo oqinileyo, ongangenekiyo wokukhusela izakhiwo ngokusebenzayo kwiziphumo ezirhabaxa zendalo. Kwinkqubo yolwakhiwo, ii-sealants zisetyenziswa ngobuchule kwizikhewu, amajoyinti, kunye nokuvuleka okufana neefestile, iingcango, i-roof seams, ii-wall panels, kunye nokungena kwezinto eziluncedo, ezizezona ndawo ziqhelekileyo zokungena emanzini. Ngokungafaniyo neecaulks eziqhelekileyo, ezihlala ziqhekeka okanye zithobeke ngokukhawuleza,{7}}izitywini zokwakha ezikumgangatho ophezulu zenzelwe ngokukodwa ukumelana neemeko zemozulu ezimandundu, kubandakanya izantyalantyala zemvula, ikhephu ixesha elide, ukuguquguquka okukhawulezileyo kwamaqondo obushushu, kunye nokuvezwa okukhulu kwe-UV, ngelixa zigcina ukuguquguquka kwazo kunye nokubambelela olomeleleyo kwiindawo ezahlukeneyo kwiminyaka emininzi.

 

Kulwakhiwo lweendawo zokuhlala, izitywini zibalulekile ekukhuseleni amakhaya ekonakalisweni kwamanzi anokonakalisa imiphetho yangaphakathi, yonakalise iinkqubo zombane, kwaye yenze buthathaka amacandelo abalulekileyo olwakhiwo olunje ngemiqadi yomthi, ukudityaniswa komgangatho, kunye neziseko zekhonkrithi. Umzekelo, ukutywina ngokufanelekileyo iifreyimu zefestile kunye nemivalo yamacango kuthintela amanzi emvula ukuba angangeni ezindongeni, nto leyo enokubangela ukuba i-drywall idumbe kwaye ibole, ipeyinti ixobulwe kwaye iqandule, kunye nokungunda kukhule kwiikona ezifihlakeleyo-imiba engapheleli nje ekuthobeni ixabiso lendlu kakhulu kodwa ibeka imingcipheko enkulu yempilo kubahlali, ngakumbi abo banengxaki yokungangeni okanye ukuphefumla. Kwizakhiwo zorhwebo, apho iifacade ezinkulu zeglasi, i-membrane yophahla olubanzi, kunye nokudibanisa okudibeneyo zizinto eziqhelekileyo, izitywini zibaluleke ngakumbi ekukhuseleni isakhiwo. Benza itywina eliqinileyo elijikeleze le mimandla isengozini, ukuthintela ukungena kwamanzi kunye nokonakalisa izixhobo ezixabisa kakhulu, iimpahla ezixabisekileyo, kunye neendawo zangaphakathi eziyilwe ngononophelo, ezinokukhokelela kwilahleko enkulu yemali kubanini bamashishini. Ukongeza, ii-sealants zinceda ukugcina amandla ombane wezakhiwo ngokuthintela ukungena kwamanzi okunokuthi kubeke esichengeni ukusebenza kwezixhobo zokugquma, okukhokelela kwiindleko eziphezulu zokufudumeza kunye nokupholisa kunye nokuchithwa kwamandla.

 

Ukusebenza kwama-sealants ekukhuseleni umonakalo wamanzi kuxhomekeke kakhulu ekukhetheni uhlobo olufanelekileyo lwe-sealant kwisicelo esithile kunye nomhlaba. Ii-Silicone sealants, umzekelo, zilungele ukusetyenziswa ngaphandle ngenxa yesakhono sazo sokuthintela amanzi, ukuxhathisa okuqinileyo kwe-UV, kunye nokuguquguquka okukhethekileyo, kuzenza zilungele ukutywina iifestile, uphahla, kunye namalungu angaphandle abhentsiswe kutshintsho lwemozulu rhoqo. Ii-polyurethane sealants, kwelinye icala, zibonelela ngokuncamathela okugqwesileyo kuluhlu olubanzi lwezixhobo ezibandakanya ikhonkrithi, isinyithi, kunye ne-masonry, ezenza zifaneleke ngakumbi ukutywina amakhonkco okwandisa kwizakhiwo zorhwebo, iibhulorho, kunye nezakhiwo zemizi-mveliso ezifumana intshukumo ebalulekileyo. Ngokwenza utyalo-mali kwizitywini{3}ezikumgangatho ophezulu kunye nokuqinisekisa ukuba zisetyenziswa ngokuchanekileyo ngabasebenzi abaqeqeshiweyo, iingcali zokwakha zinokuwunciphisa kakhulu umngcipheko wokonakaliswa kwamanzi, zandise ubomi bezakhiwo zibonke, kwaye zisindise abanini-zakhiwo kumthwalo wokulungiswa okuxabisa imali eninzi kunye nokutshintshwa kwangaphambi kwexesha ekuhambeni kwexesha.
