| 从事化工行业的朋友想必对固化剂这个产品并不陌生，固化剂是必不可少的添加物，无论是作粘接剂、涂料、浇注料都需添加固化剂，否则环氧树脂不能固化。而且固化剂的品种对固化物的力学性能、耐热性、耐水性、耐腐蚀性等都有很大影响。 Friends engaged in chemical industry must be familiar with curing agent, which is an indispensable additive. It is necessary to add curing agent for adhesives, coatings and castables. Otherwise, epoxy resin can not be cured. Moreover, the varieties of curing agents have great influence on the mechanical properties, heat resistance, water resistance and corrosion resistance of the cured products. 一般而言，纯度越高越透明。固含量是关键因素。国内混凝土因是普通硅酸盐水泥，多含有粉煤灰，加上搅拌钻的水泥量不足，及加水量偏多，所以孔隙率偏高，如固含量不足，形成硅酸钙也不足 Generally speaking, the higher the purity, the more transparent. Solid content is the key factor. gelidun.89ix.comgangguanp.89ix.comtongshizi.71ix.comzhuzaojm.37ix.com.cnBecause domestic geshanb.89ix.comtaiyangn.89ix.comconcrete is ordinary Portland cement, mostly contains fly ash, and the cement quantity of mixing drill is insufficient, and the amount of water added is too much, so the porosity of concrete is high, such as the solid content is insufficient, and the calcium silicate formed is insufficient. |
