    城市管廊聚氨酯密封膠標(biāo)準(zhǔn)

    聚氨酯建筑密封膏屬雙組份反應(yīng)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(yù)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(jié)性,(A組份:B組份=10:0.8~1.2)。

    Polyurethane building sealant is a two component reactive curing 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(jìn)行整齊處理(可用手提切割機(jī),砂輪,剛刷等),使涂膠面露出牢固的結(jié)構(gòu)層。

    Base treatment: the adhesive surface must be handled neatly (portable cutting machine, grinding wheel, rigid 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(wú)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(hù)漆也需除去。如構(gòu)筑物不干,可用噴燈烘干。
    The joint surface must be compleby dry, clean and frost free. All dust and cement slurry on the surface must be cleaned and cleaned. Rust and protective paint on bl surface also need to 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)。
    Before the first coating porous surface coating primer primer. Only need to brush a thin layer, the surface is not sticky rear can be coated with sealant. (the company is supporting the various bottom paint supply).
    特點(diǎn)
    Characteristic
    優(yōu)良的耐磨性、低溫柔軟性,性能可調(diào)節(jié)范圍較廣,機(jī)械強(qiáng)度大,粘接性好,彈性好,具有優(yōu)良的復(fù)原性,可適合動(dòng)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(jià)格低廉。
    It has excellent abrasion resistance, low softness and softness, wide range of adjustable properties, good mechanical strength, good adhesion, good elasticity, excellent resilience, and suitable for dynamic joints, debation 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(diǎn)。如:不能長(zhǎng)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?zé)岘h(huán)境下可能產(chǎn)生氣泡和裂紋;許多場(chǎng)合需要底涂。同時(shí)聚氨酯密封膠耐水性也較差,特別是耐堿水性欠佳。
    Polyurethane sealant also has some disadvantages. Such as: not long-term heat; light bula 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 also poor in water resistance, especially alkali resistance.
