Iimpawu zokuSebenza kunye noHlalutyo lweSicelo seStructural Sealant

I-Structural sealant sisixhobo sokwakha esiphezulu{0}esisebenzayo esetyenziswa ikakhulu ukudibanisa kunye nokutywina izakhiwo ezifana neendonga zekhethini, iingcango, iifestile, kunye neglasi yokugquma. Umsebenzi wayo ongundoqo kukubonelela{2}}ixesha elide, inkxaso yomatshini ezinzileyo kunye nokutywinwa kokuthintela amanzi, ukuqinisekisa ukuqina kunye nokhuseleko lwezakhiwo zokwakha.

 

Ngokubhekiselele ekusebenzeni, ii-sealants zolwakhiwo zinokunamathela okugqwesileyo, ukumelana nemozulu, kunye nokuqina. Banokuthi babophe ngokuqinileyo izinto ezahlukeneyo, njengeglasi, isinyithi, ilitye, kunye neecomposites, kwaye bahlale bezinzile kwiindawo ezirhabaxa ezinje ngokuguquguquka kobushushu, ukuvezwa kwe-UV, kunye nokhukuliseko lomoya kunye nemvula. Izitywini zezakhiwo zale mihla zisebenzisa i-silicone okanye iinkqubo ze-polyurethane eziguquliweyo, ezibonelela ngomthamo obalaseleyo wokufuduka, ukuziqhelanisa noguquko oluncinci lwesakhiwo kunye nokuthintela ukuqhekeka okanye ukugxothwa okubangelwa zizinto ezinjengokwandiswa kobushushu kunye nokucutheka kunye neenyikima.

Ngokubhekiselele kwisicelo, ii-sealants zesakhiwo zisetyenziselwa ngokubanzi ukudibanisa iglasi kwiifreyimu ze-aluminium kwiinkqubo zodonga lwamakhethini, ukutywina imida yeglasi ye-insulating, kunye neengcango zokukhusela amanzi kunye neefestile. Umzekelo, kwizakhiwo eziphakamileyo-, izitywini zesakhiwo zidlala indima ebalulekileyo ekubopheni iipaneli zeglasi kwisakhelo esixhasayo, kwaye amandla azo achaphazela ngokuthe ngqo ukhuseleko lulonke lodonga lomkhusane. Ngaphaya koko, kwizakhiwo ezenziweyo, izitywini zesakhiwo nazo zisetyenziselwa ukutywina amakhonkco ezinto ezenziweyo, ukuphucula amandla ombane wesakhiwo kunye nokungangeni komoya.

Ukukhetha i-sealant yesakhiwo esifanelekileyo kufuna ukuqwalaselwa kweemeko zokusingqongileyo, uhlobo lwe-substrate, kunye neemfuno zomthwalo. Umzekelo, imozulu ephezulu{1}}izitywini zokutywina zesilicone ezixhathisayo zilungele ukusetyenziswa kwimozulu egqithisileyo, ngelixa izitywini ezingathathi hlangothi{2}}zonyango zifaneleke kakhulu usetyenziso olufuna kungabikho mhlwa kwi substrates zentsimbi.

Kwixesha elizayo, njengoko imfuno yezakhiwo eziluhlaza kunye nogcino lwamandla kunye nokukhuselwa kokusingqongileyo ikhula, i-VOC (i-volatile organic compound) izitywini zesakhiwo ziya kuba yindlela ekhulayo, eyomeleza ngakumbi ukhuseleko lwesakhiwo kunye nokuzinza.
