抹面砂漿要求具有良好的和易性,容易抹成均勻平整的薄層,便于施工;還應(yīng)有較高的黏結(jié)力,不易開(kāi)裂或脫落。下面來(lái)講講
濟(jì)南抹面砂漿的原材料事項(xiàng)。
The plastering mortar should have good workability and be easy to apply into a uniform and flat thin layer for easy construction; It should also have a high bonding force, which is not easy to crack or fall off. Next, let's talk about the raw materials of Jinan plastering mortar.
膠凝材料
Cementitious material
抹面砂漿常用的膠凝材料有硅酸鹽水泥、鋁酸鹽水泥、石膏、石灰、樹(shù)脂、瀝青等。將著色劑混入白色水泥或者硅酸鹽水泥中制備而成的彩色水泥,可以應(yīng)用于各種裝飾墻體。
Cement materials commonly used for plastering mortar include Portland cement, Aluminate cement, gypsum, lime, resin, asphalt, etc. Colored cement prepared by mixing colorants with white cement or Portland cement can be applied to various decorative walls.
細(xì)骨料
Fine aggregate
抹面砂漿用細(xì)骨料主要分為天然砂、機(jī)制砂和工業(yè)廢渣,其中,輕骨料抹面砂漿常用的細(xì)骨料主要分為天然輕骨料、人造輕骨料和工業(yè)廢渣輕骨料三類。
Fine aggregates used for plastering mortar are mainly divided into natural sand, machine made sand, and industrial waste. Among them, the commonly used fine aggregates for lightweight aggregate plastering mortar are mainly divided into three categories: natural lightweight aggregate, artificial lightweight aggregate, and industrial waste lightweight aggregate.
摻合料
Admixture
在抹面砂漿中加入適量摻合料,能改善砂漿的和易性,達(dá)到方便施工、降低成本的目的。常用的摻合料有粉煤灰、粒化高爐礦渣、硅灰、沸石粉等。
Adding an appropriate amount of admixture to the plastering mortar can improve the workability of the mortar, achieve the goal of convenient construction and cost reduction. Commonly used admixtures include fly ash, granulated blast furnace slag, silica fume, zeolite powder, etc.

粉煤灰具有潛在化學(xué)活性,顆粒較細(xì),摻入抹面砂漿中可以發(fā)揮活性效應(yīng)、形態(tài)效應(yīng)和填充效應(yīng);粒化高爐礦渣應(yīng)用在抹面砂漿中,有利于其中的活性組分更快、更充分水化;硅灰用在抹面砂漿中可以提高砂漿的強(qiáng)度,配制出高強(qiáng)砂漿。
Fly ash has potential chemical activity, with relatively fine particles. When added to plastering mortar, it can exert activity, morphology, and filling effects; The application of granulated blast furnace slag in plastering mortar is conducive to faster and more complete hydration of the active components; The use of silica fume in plastering mortar can improve the strength of the mortar and prepare high-strength mortar.
同時(shí),還可以改善砂漿的孔結(jié)構(gòu),提高抗?jié)B性、抗凍性以及耐腐蝕性;抹面砂漿中加入沸石可以減少砂漿泌水,改善可泵性,還可以提高砂漿強(qiáng)度、密實(shí)性、抗?jié)B性和抗凍性。
At the same time, it can also improve the pore structure of mortar, improve its impermeability, frost resistance, and corrosion resistance; Adding zeolite to plastering mortar can reduce mortar bleeding, improve pumpability, and also improve mortar strength, compactness, impermeability, and frost resistance.
外加劑
admixture
外加劑可以改善砂漿性能,常用的外加劑有:聚合物乳液、可再分散乳膠粉、纖維素醚、觸變潤(rùn)滑劑、減水劑、引氣劑、早強(qiáng)劑、調(diào)凝劑、防水劑、防凍劑等。
Admixtures can improve the performance of mortar. Common admixtures include polymer lotion, redispersible emulsion powder, cellulose ether, thixotropic lubricant, water reducer, air entraining agent, early strength agent, setting modifier, waterproof agent, Antifreeze, etc.
抹面砂漿中應(yīng)用廣的聚合物乳液為醋酸乙烯-乙烯共聚物乳液,多用于外墻保溫;純丙乳液和苯丙乳液常用于防水砂漿和修補(bǔ)抹面砂漿中;可再分散乳膠粉可以提高抹面砂漿的拉伸黏結(jié)強(qiáng)度、抗折強(qiáng)度、變形能力、耐磨強(qiáng)度等;纖維素醚應(yīng)用于抹面砂漿中可起到保水、增稠、引氣、改善施工性能等方面的作用;膨潤(rùn)土作為觸變潤(rùn)滑劑,可以增加抹面砂漿的穩(wěn)定性,改善可泵性;減水劑、引氣劑、早強(qiáng)劑、調(diào)凝劑、防凍劑等對(duì)抹面砂漿起到減水、引氣、早強(qiáng)、緩凝、速凝、抗凍的作用。
The widely used polymer lotion in plastering mortar is vinyl acetate vinyl copolymer lotion, which is mostly used for external wall insulation; Pure acrylic lotion and styrene acrylic lotion are commonly used in waterproof mortar and repair plaster mortar; Redispersible latex powder can improve the tensile bonding strength, flexural strength, deformation ability, and wear resistance of plastering mortar; The application of cellulose ether in plastering mortar can play a role in water retention, thickening, air entrainment, and improving construction performance; Bentonite, as a thixotropic lubricant, can increase the stability of plastering mortar and improve its pumpability; Water reducing agent, air entraining agent, early strength agent, setting regulator, Antifreeze, etc. play the role of water reducing, air entraining, early strength, retarding, rapid setting, and antifreeze on the plastering mortar.
在抹面砂漿中加入纖維可以改善其抗裂、抗爆裂、抗凍融、抗沖擊、耐磨等性能。用來(lái)提高抹面砂漿抗裂性的纖維主要為耐堿玻璃纖維和有機(jī)合成纖維(如聚丙烯纖維、聚丙烯膳纖維、聚乙烯醇纖維等)。還有什么事兒就來(lái)我們網(wǎng)站

Adding fibers to the plaster mortar can improve its properties such as crack resistance, burst resistance, freeze-thaw resistance, impact resistance, and wear resistance. The fibers used to improve the crack resistance of plastering mortar are mainly alkali resistant glass fiber and organic Synthetic fiber (such as polypropylene fiber, polypropylene fiber, polyvinyl alcohol fiber, etc.).
