Application of calcium carbonate lime in coatings

灰钙粉，主要成分是氢氧化钙Ca（OH）2，具有白度好，细度高，无毒无味等特点，能提高涂料附着力、耐水性、耐擦洗效果、防霉吸潮特性，为涂料企业提高产品质量降低成本。

Grey calcium powder, mainly composed of calcium hydroxide Ca (OH) 2, has the characteristics of good whiteness, high fineness, non-toxic and tasteless, and can improve the adhesion, water resistance, scrub resistance, mildew resistance and moisture absorption characteristics of the coating, so as to improve the product quality and reduce the cost for the coating enterprises.

灰钙粉在涂料中的应用  Application of lime and calcium powder in coatings

从材料来看，灰钙粉是石灰通过精选加工磨成的325~600目的白色粉末。目前，使用灰钙粉生产的涂料已通过国家检测中心检测，达到GB18582-2008《室内装饰材料内墙涂料中有害物限量》检验要求。目前来看。灰钙粉广泛应用在腻子粉、OK粉、保温砂浆甚至是塑料和橡胶及食品等领域。  

From the perspective of materials, lime powder is a white powder of 325~600 mesh which is grinded by lime through selective processing. At present, the coating produced with lime and calcium powder has passed the inspection of the National Testing Center, meeting the inspection requirements of GB18582-2008 Limit of Harmful Substances in Interior Wall Coatings of Interior Decorative Materials. So far. Calcite powder is widely used in putty powder, OK powder, thermal insulation mortar and even plastic, rubber, food and other fields.

以腻子粉为例，主要原料为灰钙粉（添加比例30%）、重钙粉、胶粉粘结剂，采用干粉搅拌机，搅拌混合而成，产品环保，无毒无味。分为内墙和外墙两种。外墙腻子，要抵抗风吹日晒所以胶性大、强度高。内墙腻子，综合指数较好，环保、无毒无味。

Take putty powder as an example. The main raw materials are lime and calcium powder (adding proportion of 30%), heavy calcium powder and rubber powder binder. They are mixed by dry powder mixer. The product is environmentally friendly, non-toxic and tasteless. It is divided into internal wall and external wall. Exterior wall putty should resist the wind and sun, so its adhesive strength is high. Interior wall putty, with good comprehensive index, environmental protection, non-toxic and tasteless.
