水泥假山中的水泥砂浆辅料添加!

水泥假山是比较常见的塑石假山品种,主要采用水泥砂浆等材料制作的仿真假山,运用特制工具在水泥砂浆的表层雕刻纹理。的假山制作公司在制作水泥假山时会添加多种水泥砂浆辅料,从而增强水泥砂浆的特型,本文介绍多种水泥砂浆辅料,供大家参考。
Cement rockery is a common type of plastic rock rockery, which is mainly made of cement mortar and other materials. Special tools are used to carve texture on the surface of cement mortar. Professional rockery making companies will add a variety of cement mortar accessories when making cement rockery, so as to enhance the characteristics of cement mortar. This paper introduces a variety of cement mortar accessories for your reference.
一、抗碱玻璃纤维
1、 Alkali resistant glass fiber
抗碱玻璃纤维是一种性能优异的无机非金属材料。英文原名为:glassfiber或fiberglass。成分为二氧化硅、氧化铝、氧化钙、氧化硼、氧化镁、氧化钠等。它是以玻璃球或废旧玻璃为原料经高温熔制、拉丝、络纱、织布等工艺。水泥砂浆中添加抗碱玻璃纤维既能减少砂浆中碱液的渗出,又能增加水泥砂浆的牢固度;在水泥砂浆的搅拌中,均匀洒入抗碱玻璃纤维,与水泥砂浆充分搅拌。
Alkali resistant glass fiber is an inorganic non-metallic material with excellent properties. The original English name is glassfiber or fiberclass. The components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. It is made of glass ball or waste glass by high temperature melting, drawing, winding and weaving. Adding alkali resistant glass fiber to cement mortar can not only reduce the leakage of alkali liquor in mortar, but also increase the firmness of cement mortar; in the mixing of cement mortar, evenly sprinkle alkali resistant glass fiber, and fully mix with cement mortar.

二、羧甲基纤维素
2、 Carboxymethylcellulose
食品工业中用作增稠剂,医药工业中用作药物载体,日用化学工业中用作黏结剂、抗再沉凝剂。印染工业中用作上浆剂和印花糊料的保护胶体等。在石油化工中可作为采油压裂液成分。羧甲基纤维素在水泥砂浆中的运用比较少,仅仅运用水泥假山的制作,羧甲基纤维素能大大增加水泥砂浆的粘稠度,还能增加水泥砂浆的保水型,对水泥假山的开裂预防有很大的帮助。
It is used as thickener in the food industry, drug carrier in the pharmaceutical industry, and adhesive and anticoagulant in the daily chemical industry. It is used as a protective colloid for sizing agent and printing paste in printing and dyeing industry. It can be used as a component of oil recovery fracturing fluid in petrochemical industry. The application of carboxymethylcellulose in cement mortar is relatively small. Only using the production of cement rockery, carboxymethylcellulose can greatly increase the viscosity of cement mortar, but also increase the water retention type of cement mortar, which is very helpful to prevent the cracking of cement rockery.
三、水泥膨胀剂
3、 Cement expansion agent
水泥膨胀剂是一种化学外加剂,加在水泥中,当水泥凝结硬化时,随之体积膨胀,起补偿收缩和张拉钢筋产生预应力以及充分填充水泥间隙的作用。实际上,水泥膨胀剂是利用轻金属(主要是铝粉,近年来使用铁粉、铝粉等)与碱性水泥起化学反应,产生氢气,而使水泥体积膨,起提高水泥强度的作用,故亦有人称为水泥发泡剂。大型的水泥假山已渐渐淘汰手工抹灰,采用机喷操作,机喷砂浆对水泥砂浆的密集度有很高的要求,水泥膨胀剂的添加能增加水泥砂浆的粘稠度和体积,便于机喷的操作,也能减少材料浪费。
Cement expansion agent is a kind of chemical admixture. When the cement is set and hardened, it will expand with the volume, which can compensate the shrinkage and the prestressed of the tensioning steel bar and fill the cement gap fully. In fact, the expansion agent of cement is to use light metal (mainly aluminum powder, in recent years, iron powder, aluminum powder, etc.) to react with alkaline cement to produce hydrogen, which makes the volume of cement expand and improves the strength of cement. Therefore, it is also called cement foaming agent. The large-scale cement rockery has gradually eliminated the manual plastering, and the machine spraying operation is adopted. The machine spraying mortar has high requirements for the density of cement mortar. The addition of cement expansion agent can increase the viscosity and volume of cement mortar, facilitate the machine spraying operation, and reduce the waste of materials.
水泥砂浆中多种辅料的添加,既增加了水泥砂浆凝固后的牢固度,又能增加砂浆的初凝时间,为水泥假山的面层雕刻提供充裕时间。对整体假山的试用寿命和仿真度均起到了积极的作用。
The addition of various auxiliary materials in the cement mortar not only increases the firmness of the cement mortar after setting, but also increases the initial setting time of the mortar, providing sufficient time for the surface carving of the cement rockery. It has played a positive role in the trial life and simulation degree of the whole rockery.
