Lessen Two—Curtain Wall MaterialI Introduction:（技术简介）Normally the material of curtain wall can be divided into two parts: Main material and assistant material. Main material consists of" the following parts: glass, metal panel and stone, furthermore, metal panel includes aluminum composite panel, aluminum single panel, aluminum honeycomb panel, stainless steel, titanium alloy panel, stainless steel composite panel and steel panel. Assistant material includes: gasket, sealing sealant, mineral wool, foam bar and others.II Conversation（会话）O…Owner, C…ContractorO: How to treat the aluminum alloy surface against corrosion, please?C: We have four ways to treat them in total.1. anodizing2. electrophoresis painting3. powder painting4. PVDF paintingO: What is the difference among these four methods?C: That is a good question. Generally anodizing suits for，aluminum extrusion and comparing with' others, the cost of anodizing is the lowest one. For electrophoresis painting, actually we don't use this method very often. Powder painting and PVDF painting are normally used on outer decoration panel and the color can be of many choices・ But the effect of PVDF coating is better than that of powder coating, which also means the cost of PVDF painting is higher.O: What about steel, do you have to make any treatment on the steel surface?C: Yes, indeed. There are three ways to treat the steel surface:1. galvanizing2. inorganic zinc painting3. PVDF paintingO: We had talked about aluminum and steel, as I know, now people like to use stone as curtain wall material, do they have to make any surface treatment?C: Yes, people use granite and marble for curtain wall, but there is no special treatment on the stone surface. What we have to do is the compatibility test.O: What is compatibility test?C: Compatibility test is a kind of test to make sure two different sealing materials or sealing material in touch with other material without creating any harmful physical and chemical reaction.O: Why we need to do the compatibility test?C: Because sometimes two different materials, for example, sealant and metallic panel, when they touch each other, chemical reaction is then created and the performance and function of curtain wall will be affected. In order to ° avoid such things, we have to do this test before.O: As you mentioned, it is the compatible problem between metal and non-metal material, and how to solve the problem between two different kinds of metal materials?C: OK, when two different kinds of metal or electric conductor touch each other, it causes electrode corrosion which is called bimetallic corrosion. To avoid this, we put nylon washer between the metal and for all the fasteners we use are stainless steel.O: Most of the questions above are about metal, now I want to know something about glass・ Compared with single glass, what are the virtues of insulated glass unit?C: Certainly! The most obvious virtues is that the heat and sound insulation of IGU is better than that of single glass, but it costs more.O: I heart something named low-E glass, what is the characteristic of that?C: It can stop the heat of sunlight, meanwhile allow all the visible light, which means energy-saving.O: Sounds very nice. Recently, foil stmcture is getting more and more popular; could you please give us some brief information?• • • ⑥ •C: Yes, there are mostly two kinds of foil for construction so far . One is ETFE, which is suitable for inflated structure・ As it is transparent, we use it for facade and roof. The foil of the '"Water Cube" is just ETFE. The other is PTFE, which is opaque and suitable for tension structure・O: I got it! Thank you for your explanation!C: My pleasure! Don't hesitate to; get in touch with" me anytime!Ill Terminology（专业术语）1. metal panel:金属板2. aluminum composite panel:铝复 合板3. aluminum single panel: 铝单板4. aluminum honeycomb panel:卡吕蜂 窝板titanium alloy panel:钛合金金板6. stainless steel composite panel: 4s 锈钢复合板7. gasket:胶条& mineral wool:岩棉9. foam bar:泡沫棒10. anodizing:阳极氧化electrophoresis painting: 电泳喷涂12.
