彩钢夹芯板是由上下两层彩色涂层钢板作为面板，以保温隔热材料聚苯乙烯、聚氨脂、酚醛泡沫、岩棉等为芯材，在专用的自动化生产线上，经连续成型工艺将芯材与面板复合成整体的建筑板材，俗称为“夹芯板”。这种复合板材虽然引进我国的历史不到20年时间，但由于其具有承力、保温隔热、装饰、防水、施工简单等一系列优点，因而在建筑洁净室已得到广泛的认知和使用，对砖石等传统建筑材料提出了挑战，成为建材行业的一支新军。一、芯材种类及性能比较

　　Color steel sandwich panel is a kind of building panel, which is composed of two layers of color coated steel plates as the panel, and thermal insulation materials such as polystyrene, polyurethane, phenolic foam, rock wool, etc. as the core material. On a special automatic production line, the core material and the panel are combined into a whole through a continuous molding process, commonly known as "sandwich panel". Although this type of composite board has been introduced to China for less than 20 years, it has been widely recognized and used in building cleanrooms due to its advantages such as load-bearing capacity, thermal insulation, decoration, waterproofing, and simple construction. It challenges traditional building materials such as bricks and stones and has become a new force in the building materials industry. 1、 Comparison of Core Material Types and Properties

　　彩钢夹芯板芯材按其产品的化学成分可分为两大类，即一类是有机化学泡沫材料，如聚苯乙烯泡沫塑料EPS、聚氨酯泡沫塑料PU、挤塑聚苯乙烯泡沫XPS、酚醛泡沫塑料PF等；另一类是无机纤维材料，如岩棉板、发泡水泥板等。

　　The core materials of color steel sandwich panels can be divided into two categories according to the chemical composition of their products, namely, organic chemical foam materials, such as polystyrene foam EPS, polyurethane foam PU, extruded polystyrene foam XPS, phenolic foam PF, etc; The other type is inorganic fiber materials, such as rock wool board, foam cement board, etc.

　　1、聚氨酯泡沫彩钢夹芯板PU聚氨酯泡沫彩钢夹芯板是以阻燃型硬质聚氨酯泡沫塑料作芯材，以彩色涂层钢板为面材。目前，国内金属面硬质聚氨酯夹芯板大量应用于工业厂房、仓库、体育场馆、民用住宅、别墅、活动板房、组合式冷库等建筑，但缺点是在反应高温强碱的条件下进行，对设备要求高，初期投资较大，工业化较为困难。

　　1. Polyurethane foam color steel sandwich panel PU polyurethane foam color steel sandwich panel is made of flame retardant rigid polyurethane foam as the core material and color coated steel plate as the surface material. At present, metal faced rigid polyurethane sandwich panels are widely used in industrial plants, warehouses, sports venues, residential buildings, villas, prefabricated houses, modular cold storage and other buildings in China. However, the disadvantage is that they are carried out under high temperature and strong alkali reaction conditions, require high equipment requirements, require large initial investment, and are difficult to industrialize.

　　2、聚苯乙烯泡沫彩钢夹芯板EPS聚苯乙烯就是我们经常看见的白色泡沫，这种彩钢板便宜，耐水，不变形，工地上大部分的活动房都是用聚苯乙烯夹芯板建成的，用途广泛，但聚苯乙烯泡沫夹芯板不防火，保温效果差。

　　2. Polystyrene foam color steel sandwich panel EPS polystyrene is the white foam we often see. This color steel plate is cheap, water resistant, and does not deform. Most of the activity rooms on the site are built with polystyrene sandwich panels, which are widely used, but the polystyrene foam sandwich panel is not fireproof, and the insulation effect is the worst.

　　3、酚醛泡沫彩钢夹芯板PF酚醛泡沫彩钢夹芯板是以彩色钢板为面材，以酚醛泡沫为芯材的复合板材。酚醛泡沫脆性大，易碎，并有一定的腐蚀性，泡沫中残留的酸对金属材料有腐蚀作用。

　　3. Phenolic foam color steel sandwich panel PF phenolic foam color steel sandwich panel is a composite panel with color steel plate as surface material and phenolic foam as core material. Phenolic foam is brittle, fragile and corrosive. The residual acid in foam can corrode metal materials.

　　4、岩棉彩钢夹芯板岩棉彩钢夹芯板，防火性能比较好，但岩棉彩钢板不防水，遇火产生有毒物质，污染较大。

　　4. Rock wool color steel sandwich panel with slate and cotton color steel sandwich panel has good fire resistance, but rock wool color steel plate is not waterproof and produces toxic substances when exposed to fire, causing significant pollution.

　　5、纸蜂窝彩钢夹芯板纸蜂窝夹芯板可对废弃物完全回收再利用，是聚苯板、聚氨脂、岩棉等材料的换代产品，广泛应用于电子、医院手术室、实验室等洁净工程领域，但防水效果差，较贵。

　　5. Paper honeycomb color steel sandwich panel can completely recycle and reuse waste, and is a replacement product for materials such as polystyrene board, polyurethane, rock wool, etc. It is widely used in clean engineering fields such as electronics, hospital operating rooms, laboratories, etc. However, the waterproof effect is poor and the price is relatively expensive.

　　6、铝峰窝夹芯板铝蜂窝彩钢夹芯板，它是由以铝蜂窝芯板材，采用特制高强度胶水与彩钢板复合，并由特制铝合金龙骨支撑，经加温、加压、固化后而制成。与其它夹芯板相比，重量轻，平直度好，属于绿色建材，但造价。

　　6. Aluminum honeycomb sandwich panel, aluminum honeycomb color steel sandwich panel, is made of aluminum honeycomb core board, composite with special high-strength glue and color steel plate, supported by special aluminum alloy keel, and made by heating, pressing, and curing. Compared with other sandwich panels, it is lightweight, has good flatness, and belongs to green and environmentally friendly building materials, but the cost is the highest.

　　10. What are the design methods for generating preload of ball screws? What are the differences?

　　1)导程偏移预压方式:(加大节距或缩小节距)特征:在螺母节距上作δ值的偏移来取代传统双螺母预压方式，此方式较适用于中轻预压，将预压力设计在5%动负荷以下。2)拉伸预压方式 特征:使用一过厚的预压片将两个螺母外张方式达到预压之效果，此为HIWIN精密级滚珠丝杠常使用的方式。

　　1) Lead offset preloading method: (increase pitch or decrease pitch) Features: Use a delta offset on the nut pitch to replace the traditional double nut preloading method. This method is more suitable for medium to light preloading, and it is best to design the preloading below 5% dynamic load. 2) Characteristics of stretching and preloading method: Using an excessively thick preloading plate to externally stretch two nuts to achieve preloading effect, this is the most commonly used method for HIWIN precision grade ball screws.
