石膏是一種微溶于水的物質(zhì)！

來源：http://www.wavc.cn 日期：2019-07-10 發(fā)布人：

　　脫硫石膏粉生產(chǎn)設備應注意石膏砌塊的選擇

　　The selection of gypsum block should be paid attention to in the production equipment of desulfurized gypsum powder

　　1、脫硫石膏粉生產(chǎn)設備耐水。石膏是一種微溶于水的材料，在可能與水接觸的地方，建議采取嚴格的防水措施。例如，生產(chǎn)砌塊時，在配料中加入防水劑或防水劑外加劑，根據(jù)可能與水接觸的程度，在隔墻上涂上部分或全部防水貼面或涂料;縫隙和孔洞建議用密封劑密封;此外，在砌筑隔墻之前，還可以制作磚或混凝土墻板。

　　1. Water resistance of desulfurization gypsum powder production equipment. Gypsum is a kind of slightly soluble material in water. Strict waterproofing measures must be taken where it may come into contact with water. For example, in the production of blocks, waterproofing agents or waterproofing additives are added to the ingredients, and some or all waterproofing veneers or coatings are applied to the partition walls according to the degree of possible contact with water; crevices and holes must be sealed with sealants; in addition, bricks or concrete wall panels can be made before partition walls are built.

　　2、板裂縫。各種輕隔板裂縫已成為普遍存在的問題。主要原因有材料問題、分區(qū)結(jié)構(gòu)問題、分區(qū)與主結(jié)構(gòu)連接問題。

　　2. Plate cracks. All kinds of light partition cracks have become a common problem. The main reasons are material problems, partition structure problems and connection between partition and main structure problems.

　　3、輕質(zhì)隔斷材料。它可以分為兩類:一類是基于水泥或硅酸鹽的，另一類是基于石膏的。前者的水化產(chǎn)物主要為膠體，后者為晶體。膠體在外界溫度和濕度變化時容易產(chǎn)生膨脹和收縮，后者變化很小。與板相比，砌塊隔斷砌體接縫較短，只要選用合適的接縫材料，施工方法正確，石膏砌塊隔斷的裂縫完全可以解決。

　　3. Light partition material. It can be divided into two categories: one is based on cement or silicate, and the other is based on gypsum. The hydration products of the former are mainly colloidal, while the latter are crystals. Colloids tend to expand and contract when the external temperature and humidity change, while the latter changes little. Compared with the slab, the joint of block partition masonry is shorter. As long as the suitable joint material is selected and the construction method is correct, the crack of gypsum block partition can be completely solved.

　　4、石膏砌塊隔墻隔音。建設部組織編制的《住宅構(gòu)件非承重內(nèi)隔墻技術(shù)條件》中規(guī)定，住宅隔墻的空氣聲學計室內(nèi)不應小于50dB，野外不應小于45dB。機組內(nèi)隔墻氣聲計實驗室不小于35dB，現(xiàn)場不小于30dB。我國現(xiàn)有的非承重內(nèi)隔墻難以滿足家庭墻的要求，需要采取必要的技術(shù)措施，如雙層法;在隔墻上加一層隔音層。

　　4. Sound insulation of gypsum block partition wall. According to the Technical Conditions for Non-Bearing Internal Partitions of Residential Components compiled by the Ministry of Construction, the indoor air acoustics meter for residential partitions should not be less than 50 dB and the field should not be less than 45 dB. The Laboratory of aeroacoustic meter for inner partition wall of unit is not less than 35dB, and the field is not less than 30dB. The existing non-load-bearing internal partition wall in our country is difficult to meet the requirements of the family wall. Necessary technical measures, such as double-layer method, are needed, and a sound insulation layer is added to the partition wall.

　　5. 價格。單看石膏砌塊的價格，略高于其他類型砌塊，但它施工簡單，效率高，節(jié)省抹灰，施工干燥，性價比高。

　　5. Price. Looking at the price of gypsum block, it is slightly higher than other types of block, but its construction is simple, efficient, saving plastering, dry construction, high cost performance.
