碳酸鈣對膩子粉操作中的影響！

來源：http://m.wavc.cn 日期：2019-05-29 發(fā)布人：

　　Caco3對膩子粉在實際操作中的影響，膩子粉是一種墻面平整、修復(fù)的基材，是裝修中不可缺少的裝飾材料。膩子粉一般由粘結(jié)劑、填料、水和添加劑組成。

　　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.

　　膩子粉價格膩子粉可分為普通型膩子(Y型)和耐水性膩子(N型)。通用型膩子(Y型)主要用于不需要防水的地方。它由碳酸鈣雙飛粉、淀粉膠和纖維素組成。

　　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.

　　耐水膩子(N型)主要用于耐水、粘結(jié)強度要求高的地方。由碳酸鈣雙飛粉、石灰鈣粉、水泥、有機膠粉、保水劑等組成。耐水內(nèi)墻膩子重碳酸鈣含量一般占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%.

　　膩子粉批發(fā)在涂料中是用來填充底面的，是整個涂料的中間層，無論膩子需要添加什么填料。乳化漆的各種內(nèi)、外墻產(chǎn)品和配套使用的填料是膩子基本上以重碳酸鈣給高的地方,幾個添加一些鋅鋇白增加粘性,以防止漆層放松,同時適當增加輕質(zhì)碳酸鈣為干燥后光澤。

　　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.

　　實際操作中碳酸鈣對膩子粉的影響

　　Effect of Calcium Carbonate on Putty Powder in Practical Operation

　　(1)開裂問題

　　(1) Cracking

　　碳酸鈣填料粒度不能太細，碳酸鈣填料細度高，需要較多的水泥粘結(jié)，且會引起較大的干燥收縮。批吹一段時間后未及時涂漆，用子膜鉆會出現(xiàn)細小裂紋。

　　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.

　　(2)平滑問題

　　(2) Smoothing problem

　　碳酸鈣填料細度過厚，會導(dǎo)致膩子粗糙，墻面不光滑。碳酸鈣填料的細度要適當，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)粘度問題

　　(3) Viscosity

　　輕碳酸鈣的用量會導(dǎo)致膩子過厚，這時應(yīng)減少或不輕碳酸鈣。

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

　　(4)涂層光澤問題

　　(4) Gloss of coatings

　　輕質(zhì)碳酸鈣的用量越大，薄膜的光澤度越高。鑒于膜光澤有不良影響的各種因素，如成分材料的使用，應(yīng)適當增加基材或輕質(zhì)碳酸鈣的用量。

　　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)涂層硬度低

　　(5) Low hardness of coating

　　灰質(zhì)鈣粉質(zhì)量差或用量不足，敷料用量少，碳酸鈣填料過細會造成涂層硬度低。

　　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.
