Ucango kunye nefestile yefestile: Isixhobo esiphambili sokwakha ukuSebenza koMbane kunye nokuthuthuzela

Izitywini zokuvala umnyango kunye neefestile, njengezinto ezibalulekileyo ekwenziweni kweenkcukacha zesakhiwo, zidlala indima ebalulekileyo ekuphuculeni ukungangeni komoya kwesakhiwo, ukungangeni kwamanzi, kunye nokusebenza kakuhle kwamandla. Umsebenzi wabo ongundoqo ukugcwalisa izithuba phakathi kweengcango kunye neefestile zefestile, iindonga, kunye neglasi, ukuthintela ngokufanelekileyo ukungena komoya, ukungena kwamanzi emvula, kunye nokulahlekelwa kwamandla, ngaloo ndlela kuqinisekiswe induduzo yangaphakathi kunye nokuqina kwesakhiwo sokwakha.

 

Ngokusekwe kuhlobo lwemathiriyeli, izitywini zomnyango kunye neefestile zikwahlulahlulwe ngokwezigaba ezintathu: ii-silicone sealants, ii-polyurethane sealants, kunye ne-modified silane sealants. Izitywini zeSilicone, ezinemozulu entle kunye nokuxhathisa kwe-UV, zisetyenziswa kakhulu{1}}ukutywinwa kwexesha elide kucango kunye namalungu efestile. Ii-polyurethane sealants, kunye -nokuqina kwazo okuphezulu kunye ne-elastic recovery, zilungele iindawo eziphantsi kwemithwalo ephezulu. Ii-silane sealants ezilungisiweyo, kunye nokukhutshwa kwazo okuphantsi kwe-VOC kunye neempawu ezihambelana nokusingqongileyo, ziba yinto ekhethwayo kwizakhiwo eziluhlaza.

Ngethuba lokusetyenziswa, umgangatho wesicelo se-sealant uchaphazela ngokuthe ngqo ukusebenza kwayo. Ngaphambi kokufaka isicelo, coca ngokucokisekileyo umphezulu we-substrate ukuqinisekisa ukuba awunayo ioli, uthuli kunye nobunye ukungcola. Khetha i-primer efanelekileyo ngokusekelwe kwiimpawu zezinto eziphathekayo ukunyusa ukunamathela. Xa ufaka i-sealant, qinisekisa ukuqina kwe-sealant eqhubekayo kunye nefanayo (ngokucetyiswayo ngokubanzi ukuba ibe yi-6-12mm), kwaye usebenzise iindlela ezifanelekileyo zokugqiba ukuphepha amaqamza okanye ukuqhekeka. Ngaphaya koko, amandla okufuduswa kwesitywina kufuneka ahambelane nokwandiswa kunye nokucutheka kwesakhiwo, kufuna ngokubanzi inqanaba lokufuduswa kwe-20% -35% ukulungiselela intshukumo yesakhiwo ebangelwa kukuguquguquka kobushushu.

Ngophuculo oluqhubekayo lokwakha{0}imigangatho yokonga amandla,{1}}ukusebenza okuphezulu kocango kunye nezitywini zefestile zijonge ukuya kwimodyuli esezantsi, ukunwebeka okuphezulu, ukuvumelana kokusingqongileyo, kunye nokuqina. Ukukhethwa okufanelekileyo kunye nokusetyenziswa okusemgangathweni kwama-sealants akukwazi ukunciphisa kakhulu ukusetyenziswa kwamandla okwakhiwa kunye nokwandisa ubomi benkonzo yeengcango kunye neefestile, kodwa kwakhona ukubonelela ngendawo ephilileyo kunye nekhululekile yangaphakathi kubahlali. Licandelo lobugcisa elibalulekileyo kulwakhiwo lwangoku olusulungekileyo.
