The influence of Caco3 on putty powder in practical operation. Putty powder is a kind of base material for smooth wall surface and repairing. It is an indispensable decorative material in decoration. Putty powder is generally composed of binders, fillers, water and additives.

　　腻子粉价格腻子粉可分为普通型腻子(Y型)和耐水性腻子(N型)。通用型腻子(Y型)主要用于不需要防水的地方。它由碳酸钙双飞粉、淀粉胶和纤维素组成。

　　Putty powder price Putty powder can be divided into ordinary putty (Y type) and water-resistant putty (N type). General purpose putty (Y type) is mainly used in places where waterproofing is not required. It consists of calcium carbonate fly powder, starch gum and cellulose.

　　耐水腻子(N型)主要用于耐水、粘结强度要求高的地方。由碳酸钙双飞粉、石灰钙粉、水泥、有机胶粉、保水剂等组成。耐水内墙腻子重碳酸钙含量一般占70%-80%。

　　Water-resistant putty (N-type) is mainly used in places where water resistance and bonding strength are required. It is composed of calcium carbonate flying powder, lime calcium powder, cement, organic rubber powder, water retaining agent, etc. The content of calcium bicarbonate in waterproof interior wall putty generally accounts for 70%-80%.

　　腻子粉批发在涂料中是用来填充底面的，是整个涂料的中间层，无论腻子需要添加什么填料。乳化漆的各种内、外墙产品和配套使用的填料是腻子基本上以重碳酸钙给高的地方,几个添加一些锌钡白增加粘性,以防止漆层放松,同时适当增加轻质碳酸钙为干燥后光泽。

　　Putty powder wholesale in the paint is used to fill the bottom, is the middle layer of the whole paint, no matter what filler the putty needs to add. All kinds of interior and exterior wall products of emulsifying paint and the supporting fillers are putty which is basically given the highest place by calcium bicarbonate. Several zinc barium white additions are added to increase the stickiness to prevent the paint layer from relaxing, and at the same time, light calcium carbonate is appropriately added as the luster after drying.

　　实际操作中碳酸钙对腻子粉的影响

　　Effect of Calcium Carbonate on Putty Powder in Practical Operation

　　(1)开裂问题

　　(1) Cracking

　　碳酸钙填料粒度不能太细，碳酸钙填料细度高，需要较多的水泥粘结，且会引起较大的干燥收缩。批吹一段时间后未及时涂漆，用子膜钻会出现细小裂纹。

　　The particle size of calcium carbonate filler can not be too fine, and the fineness of calcium carbonate filler is high, which requires more cement bonding and will cause larger drying shrinkage. If the paint is not painted in time after batch blowing for a period of time, small cracks will appear when the sub-membrane drill is used.

　　(2)平滑问题

　　(2) Smoothing problem

　　碳酸钙填料细度过厚，会导致腻子粗糙，墙面不光滑。碳酸钙填料的细度要适当，一般控制在250-300目

　　Calcium carbonate filler is too fine, which will lead to rough putty and non-smooth wall. The fineness of calcium carbonate filler should be appropriately controlled at 250-300 mesh.

　　(3)粘度问题

　　(3) Viscosity

　　轻碳酸钙的用量会导致腻子过厚，这时应减少或不轻碳酸钙。

　　The amount of light calcium carbonate will lead to excessive thickness of putty, which should be reduced or not light calcium carbonate.

　　(4)涂层光泽问题

　　(4) Gloss of coatings

　　轻质碳酸钙的用量越大，薄膜的光泽度越高。鉴于膜光泽有不良影响的各种因素，如成分材料的使用，应适当增加基材或轻质碳酸钙的用量。

　　The higher the amount of light calcium carbonate, the higher the glossiness of the film. In view of various factors that have adverse effects on the gloss of the film, such as the use of constituent materials, the amount of substrates or light calcium carbonate should be increased appropriately.

　　(5)涂层硬度低

　　(5) Low hardness of coating

　　灰质钙粉质量差或用量不足，敷料用量少，碳酸钙填料过细会造成涂层硬度低。

　　The poor quality or insufficient dosage of lime calcium powder, less dosage of dressing, and too fine calcium carbonate filler will result in low hardness of coating.
