Ingaba uyazi? Ebusika, i-structural sealant nayo iya kufana nomntwana, okwenza umsindo omncinci, ngoko yintoni ingxaki eya kubangela?
1.Ukujiya kwe-sealant yesakhiwo
Izitywini zesakhiwo ziya kutyeba ngokuthe chu kwaye zibe lulwelo oluncinci njengoko ubushushu behla. Kwi-sealant ye-structural sealant yamacandelo amabini, ukugqithwa kwe-sealant yesakhiwo kuya kwandisa uxinzelelo lomatshini weglue kunye nokunciphisa ukukhutshwa kwe-sealant yesakhiwo. Kwicandelo elilodwa le-sealant yesakhiwo, i-sealant yesakhiwo iyaqina, kunye noxinzelelo lwe-glue gun ukukhupha i-structural sealant yanda, kwaye ukusebenza kwezandla kunokuziva kuchitha ixesha kwaye kunzima.
Isisombululo: Ukuba akukho mpembelelo ekusebenzeni kakuhle kokwakhiwa, ukunyuswa kweqondo lokushisa eliphantsi yinto eqhelekileyo, kwaye akukho manyathelo okuphucula afunekayo. Ukuba ichaphazela ukusebenza kakuhle kolwakhiwo, unokuqwalasela ukwandisa ubushushu bokusetyenziswa kwe-sealant yesakhiwo okanye wamkele amanyathelo ancedisayo okufudumeza, njengokugcina i-sealant yesakhiwo kwindawo yokufudumeza okanye igumbi eline-air-conditioning kwangaphambili. Faka ukufudumeza kwi-workshop ye-gluing ukwandisa ubushushu bendawo ye-gluing. Ukongeza, unokukhetha izixhobo ezifanelekileyo zeglue, njengemipu yeglue ye-manual ene-high thrust, i-pneumatic glue guns, imipu yeglue yombane, njl.
2.I-Weathering sealant bulges - imbonakalo engalinganiyo
Ebusika, umahluko wobushushu phakathi kwemini nobusuku udla ngokuba mkhulu. Xa isetyenziswe kudonga lwamakhethini epaneli ye-aluminiyam, i-sealant echasene nemozulu iyakwazi ukuqhuma. Esona sizathu sikukuba isantya sokunyanga isitywini esimelana nemozulu siyacotha kwindawo yobushushu obuphantsi, kwaye ixesha elifunekayo ukuze umphezulu unyange kubunzulu obaneleyo liya kuba lide. Kumphezulu we-sealant engamelana nemozulu Xa ubunzulu beglue bungakhange bunyangelwe ngokwaneleyo, ukuba ububanzi beglue seam buhluka kakhulu (oku kudla ngokubangelwa kukwandiswa kwe-thermal kunye nokuncipha kwepaneli), umphezulu weplanga umthungo weglue uya kuchaphazeleka kwaye ukungalingani kuya kuvela. Emva kokuba i-adhesive seam enomgangatho ongalinganiyo ekugqibeleni iphilisiwe, ingaphakathi layo liqinile, lingenalo i-hollow, elingayi kuchaphazela ukusebenza kokutywinwa kwexesha elide le-sealant yokumelana nemozulu, kodwa kuchaphazela kuphela ukucaca kokubonakala kwe-adhesive seam.
Emva kobusika, indawo enkulu iyaphola, iqondo lobushushu liphantsi, kwaye umahluko wobushushu phakathi kwasekuseni nangokuhlwa mkhulu. Ngenxa ye-coefficient enkulu yokwandiswa komgca wezinto eziphathekayo, udonga lwamakhethini epaneli ye-aluminium lugrumba kakhulu ngobushushu. Ngaphantsi kweemeko ezingentla zokwakhiwa kwe-sealant yesakhiwo, kukho ithuba elithile lokuba i-glue joints of the aluminiyam panel panel curtain wall will be bulge.
Isisombululo:
1.Khetha i-glue ngesantya esikhawulezayo sokunyanga, esinokunciphisa ngokulinganisela ingxaki ye-bulging ye-sealant yokumelana nemozulu.
2.Ukuba i-deformation ehambelanayo yokudibanisa iglue inkulu kakhulu ngenxa yomswakama ophantsi okanye umahluko weqondo lokushisa, iglue ubukhulu obudibeneyo, njl., Kucetyiswa ukuba ukhethe enye okanye ngaphezulu kwezi ndlela zilandelayo zokwakha.
a) Thatha amanyathelo afanelekileyo e-shading, njengokukhusela i-scaffolding kunye neenatha ezinothuli, ukwenzela ukuba iipaneli zingabonakali ngokuthe ngqo ekukhanyeni kwelanga, ukunciphisa ukushisa kweepaneli, kunye nokunciphisa ukuguqulwa kwamalungu okubangelwa ukuhluka kweqondo lokushisa.
b)Zama ukucwangcisa igluing emini emaqanda, kwaye ugweme ukuncamathelisa kusasa nangokuhlwa.
c) .Sebenzisa indlela yokusetyenziswa kweglue yesibini (oko kukuthi, ukuba kukho i-concave glue seam kwisicelo sokuqala seglue, inokunyangwa iintsuku ezi-2 ukuya kwezi-3, kwaye emva kokuba ine-elasticity, umaleko weglue wongezwa kuyo. umphezulu).
