高模量聚氨酯密封膏密度 聚氨酯建筑密封膏屬雙組份反應固化型，有A、B兩組份組成。A組分為乳白色或淺黃色粘稠狀聚氨酯預聚體，B組分為固化劑與助劑等混合脫水而成的黑色膏狀體或液體，固化后具有一定的彈性及粘結性，（A組份：B組份=10：0.8～1.2）。 Polyurethane building sealant is a two component reaction solidification type, consisting of two components of A and B. The A component is milky white or light yellow viscous polyurethane prepolymer, and group B as curing agent and additives mixed dehydration black paste or liquid, after curing with elasticity and adhesion of the (A group: B group =10:0.8 ~ 1.2).原理 principle 基層處理：被粘面必須進行整齊處理（可用手提切割機，砂輪，剛刷等），使涂膠面露出牢固的結構層。 Base treatment: the sticky surface must be handled neatly (portable cutting machine, grinding wheel, brush, etc.), so that the surface of the coating is exposed to a solid structure layer. 接縫表面必須保證完全干燥、清潔、無霜。表面所有灰塵和水泥稀漿必須清刷處理干凈。金屬表面的銹層及保護漆也需除去。如構筑物不干，可用噴燈烘干。 The joint surface must be completely dry, clean and frost free. All dust and cement on the surface must be cleaned and treated cleanly. Rust and protective paint on the metal surface must also be removed. Such structures do not use torch drying. 多孔表面涂膠前需先涂底涂料. 底涂料只需刷涂一薄層,待其表面不粘手后方可涂密封膠嵌縫.（本公司有配套的各種底涂料供給）。
高模量聚氨酯密封膏密度
特點 Characteristic 優(yōu)良的耐磨性、低溫柔軟性，性能可調節(jié)范圍較廣，機械強度大，粘接性好，彈性好，具有優(yōu)良的復原性，可適合動態(tài)接縫和變形縫、伸縮縫。耐候性好，耐油性優(yōu)良，耐生物老化且價格低廉。 The utility model has the advantages of good abrasion resistance, low softness, softness, wide range of performance adjustment, strong mechanical strength, good adhesive property, good elasticity, excellent resilience, and can be suitable for dynamic seams and deformation joints and expansion joints. Good weather resistance, good oil resistance, aging resistance and low price. 聚氨酯密封膠也有一些缺點。如：不能長期耐熱；淺色配方容易受紫外光老化；單組分膠貯存穩(wěn)定性受包裝及外界影響較大，通常固化較慢；高溫熱環(huán)境下可能產生氣泡和裂紋；許多場合需要底涂。同時聚氨酯密封膠耐水性也較差，特別是耐堿水性欠佳。 Polyurethane sealants also have some disadvantages. Such as: not long-term heat; light formula vulnerable to UV aging; single component storage stability by packaging and external influence, usually curing slowly; may produce bubbles and cracks under high temperature environment; many occasions need primer. At the same time, polyurethane sealant is poor in water resistance, especially alkali resistance, poor water quality. 適用范圍 Scope of application 該產品使用于土木建筑業(yè)、交通運輸業(yè)、混凝土預制件等建材的連接及施工縫的填充密封。高級道路、橋梁、飛機跑道、地下管道、接頭處的連接密封以及隧道和建筑物的伸縮縫與變形縫。 The product is used in the construction of civil engineering, transportation, precast concrete and other construction materials and sealing of construction joints. Connections and seals for advanced roads, bridges, runways, underground pipes, joints, and expansion and deformation joints of tunnels and structures. 注意事項 Matters needing attention 一、建筑物必須保持干燥、干凈、無油污。 First, the building must be kept dry, clean and free from oil pollution. 二、在施工前應先將底涂液涂于表面，待表面干燥后把縫隙的兩邊10mm處貼上50mm寬的防護膠帶，以防施工中多余的聚硫膠把構筑物表面弄臟。 Two, before construction, should be applied to the surface of the bottom coating liquid, to dry the surface after the gap on both sides of the 10mm affixed to the 50mm wide protective tape, in case the construction of excess polysulfide glue to the surface of the structure of pollution. 三、 把箱內1桶白色聚硫膠（A組份）與1袋黑色固化劑（B組份）充分攪拌均勻，直到無色差為止。 Three, the box 1 barrels of white polysulfide glue (A component) and 1 bags of black curing agent (B component) fully mixing, until there is no color difference so far. (注：因氣候不同B組份應冬季多、夏季少）A：B=10：0.8-1.2，用前應先做小試。 (Note: due to different climate, B group should be more winter, Xia Jishao) A:B=10:0.8-1.2, should be tested before use. 四、把攪拌好的聚硫密封膠用灰刀或擠膠槍填入縫內壓實填滿，再用≥10cm寬膩子刀把膠刮平。 Four, the polysulfide sealant with grey knife or glue gun to fill the slot fill the well mixed and compacted, more than 10cm wide rubber scraping putty knife. 高模量聚氨酯密封膏密度
