(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.

粘接宽度是玻璃面板与框架粘接丁基防水嵌缝胶的宽度，风荷载作用于面板通过周边粘接丁基防水嵌缝胶传递到金属框架，要有足够的粘接宽度(Cs)保证丁基防水嵌缝胶的安全应力水平。丁基防水嵌缝胶的强度设计值在粘接设计中都采相同强度设计值(与丁基防水嵌缝胶模量无为，粘接宽度按下式计算:

—在风荷载作用下:

CS wa/2000f,

—在风荷载和水平地震作用下:

Cs (w+O.SqE)a/2000f,

—在玻璃永久荷载作用下:

CS qab/( a+b) 2000fz

—水平倒挂的隐框、半隐框玻璃和铝框之间:

GS wa12000f,+qa/2000f2式中:

C一丁基防水嵌缝胶的粘接宽度(mm);

—作用在计算单元上的风荷载设计值(kN/m2 );

a,b—矩形玻璃板的短边和长边长度(mm);

f,—丁基防水嵌缝胶在风荷载或地震作用下的强度设计值，取0.2N/mm2;

f2—丁基防水嵌缝胶在永久荷载作用下的强度设计值，取0.01 N/mmz ;

q一作用在计算单元上的地震作用设计值(kN/m2 );

q一幕墙玻璃单位面积重力荷载设计值(kN/m2)。

粘接厚度是指丁基防水嵌缝胶粘结玻璃和框架之间的粘层厚度，是丁基防水嵌缝胶粘接拉伸位移方向的丁基防水嵌缝胶尺寸。粘接厚度取决于设计荷载和结构型式，主要是水平荷载和其他形式的副荷载引起的位移，包括设计风荷载、结构分割和玻璃尺寸、金属框架与玻璃之间热位移、地震位移等。在位移量( us)给定条件下，选择丁基防水嵌缝胶粘接厚度(is)或选择丁基防水嵌缝胶的模量(s值)按下式计算:

—结构位移横向拉动粘接丁基防水嵌缝胶。
