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.

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%.

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.

Effect of Calcium Carbonate on Putty Powder in Practical Operation
(1)開(kāi)裂問(wèn)題
(1) Cracking
碳酸鈣填料粒度不能太細(xì)八毯，碳酸鈣填料細(xì)度高搓侄，需要較多的水泥粘結(jié)，且會(huì)引起較大的干燥收縮予乏。批吹一段時(shí)間后未及時(shí)涂漆偿寥，用子膜鉆會(huì)出現(xiàn)細(xì)小裂紋。
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.

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)粘度問(wèn)題
(3) Viscosity
輕碳酸鈣的用量會(huì)導(dǎo)致膩?zhàn)舆^(guò)厚怜人，這時(shí)應(yīng)減少或不輕碳酸鈣愚缔。
The amount of light calcium carbonate will lead to excessive thickness of putty, which should be reduced or not light calcium carbonate.
(4)涂層光澤問(wèn)題
(4) Gloss of coatings
輕質(zhì)碳酸鈣的用量越大，薄膜的光澤度越高秘驻。鑒于膜光澤有不良影響的各種因素值豫，如成分材料的使用，應(yīng)適當(dāng)增加基材或輕質(zhì)碳酸鈣的用量戳明。
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)涂層硬度低
(5) Low hardness of coating
灰質(zhì)鈣粉質(zhì)量差或用量不足澈拖，敷料用量少，碳酸鈣填料過(guò)細(xì)會(huì)造成涂層硬度低赋焕。
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.
