(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

主要介紹了現(xiàn)代應(yīng)用的建筑幕墻接縫丁基防水嵌縫膠的分類、性能、膠縫表示方法以及膠縫的寬、厚設(shè)計(jì)。建筑幕墻是建筑的組成部分,建筑是由不同材料、構(gòu)件和部件組合連接的構(gòu)筑體,各種應(yīng)力和變位特征將會(huì)集中表現(xiàn)在結(jié)構(gòu)的連接接縫,各種液體、氣體、粉體、振動(dòng)波和熱介質(zhì)也將接縫作為流動(dòng)的通道,接縫的設(shè)置和密封影響著建筑的功能質(zhì)量并關(guān)系到建筑耐久安全,為此已于2008年2月1日開始執(zhí)行的GB/T 21086-2007《建筑幕墻》標(biāo)準(zhǔn)第5.3.3.1條b)規(guī)定了幕墻接縫丁基防水嵌縫膠性能應(yīng)符合該標(biāo)準(zhǔn)附錄A中A.3的相關(guān)規(guī)定,位移能力級(jí)別應(yīng)符合設(shè)計(jì)位移量的要求,不宜小于20級(jí)。
包括嵌縫膏、丁基防水嵌縫膠和結(jié)構(gòu)丁基防水嵌縫膠,并按下列不同方法進(jìn)行分類:
a)按產(chǎn)品適用于基材:玻璃(代號(hào):G);金屬(代號(hào):M);混凝土、水泥砂漿(代號(hào):C);其他(代號(hào):Q);
b)按適用功能(位移能力及模量)分級(jí)(見表1);
級(jí)別—按位移能力分為25級(jí)、20級(jí)、12.5級(jí)和7.5級(jí)四個(gè)級(jí)別;
次級(jí)品—按模量劃分僅對(duì)符合25級(jí)和20級(jí)的丁基防水嵌縫膠分為低模量(代號(hào):LM)和高模量(代號(hào):HM); 12.5級(jí)以下的丁基防水嵌縫膠按彈性恢復(fù)率分為彈性體(代號(hào):12.5E)、塑性體(代號(hào):12.5P)和塑性嵌縫膏(代號(hào):7.5P)。
c)按型別原則:
—按流動(dòng)性分為:非下垂}(N)、自流平}(L)}
—按組分?jǐn)?shù)分為:建筑硅嗣丁基防水嵌縫膠單組分(1)、雙組分(2);其他丁基防水嵌縫膠單組分(I)、雙組分(II)或多組分;
—按適用季節(jié)分為:夏季型(S)、冬季型(W)、全年型(A);
d)按固化機(jī)理分為:濕氣固化型(K)、化學(xué)反應(yīng)固化型(Z)、溶劑揮發(fā)固化型(Y)、水乳液干燥固化型(E)(硅銅建筑丁基防水嵌縫膠則分為A型—脫酸即酸性,B型—脫醇即中性二種);
e)按固化速度分為(用于環(huán)氧丁基防水嵌縫膠):快固型(K)和普通型(P);
f)按基體樹脂分為(用于非結(jié)構(gòu)承載用石材粘膠劑):不飽和聚醋樹脂型(UP)和環(huán)氧樹脂型(EP);雙組分分為基體樹脂組分(A)和固化劑組分(B);
g)按用途分為(用于非結(jié)構(gòu)承載用石材粘膠劑):適用于耐水要求較高的產(chǎn)品(I)、適用于耐水一般要求的產(chǎn)品(B):
h)按用途分為(用于硅銅建筑丁基防水嵌縫膠):鑲裝玻璃用(G類),建筑接縫用(F類);
i)按基礎(chǔ)聚合物:硅銅聚合物(SR)、聚硫橡膠(PS),聚氨脂甲酸脂(PU)、丙烯酸脂聚合物(AC)、丁基(BR)、丁基橡膠(BU),氯丁橡膠(CR)、丁苯橡膠(SB)、瀝青、油性樹脂及各種新發(fā)展的改性硅酮聚合物(MS)。www.caffertyclinic.com
