彩鋼夾芯板是由上下兩層彩色涂層鋼板作為面板，以保溫隔熱材料聚苯乙烯、聚氨脂、酚醛泡沫、巖棉等為芯材，在專用的自動化生產線上，經連續成型工藝將芯材與面板復合成整體的建筑板材，俗稱為“夾芯板”。這種復合板材雖然引進我國的歷史不到20年時間，但由于其具有承力、保溫隔熱、裝飾、防水、施工簡單等一系列優點，因而在建筑潔凈室已得到廣泛的認知和使用，對磚石等傳統建筑材料提出了挑戰，成為建材行業的一支新軍。一、芯材種類及性能比較

　　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

　　彩鋼夾芯板芯材按其產品的化學成分可分為兩大類，即一類是有機化學泡沫材料，如聚苯乙烯泡沫塑料EPS、聚氨酯泡沫塑料PU、擠塑聚苯乙烯泡沫XPS、酚醛泡沫塑料PF等；另一類是無機纖維材料，如巖棉板、發泡水泥板等。

　　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、聚氨酯泡沫彩鋼夾芯板PU聚氨酯泡沫彩鋼夾芯板是以阻燃型硬質聚氨酯泡沫塑料作芯材，以彩色涂層鋼板為面材。目前，國內金屬面硬質聚氨酯夾芯板大量應用于工業廠房、倉庫、體育場館、民用住宅、別墅、活動板房、組合式冷庫等建筑，但缺點是在反應高溫強堿的條件下進行，對設備要求高，初期投資較大，工業化較為困難。

　　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、聚苯乙烯泡沫彩鋼夾芯板EPS聚苯乙烯就是我們經常看見的白色泡沫，這種彩鋼板便宜，耐水，不變形，工地上大部分的活動房都是用聚苯乙烯夾芯板建成的，用途廣泛，但聚苯乙烯泡沫夾芯板不防火，保溫效果差。

　　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、酚醛泡沫彩鋼夾芯板PF酚醛泡沫彩鋼夾芯板是以彩色鋼板為面材，以酚醛泡沫為芯材的復合板材。酚醛泡沫脆性大，易碎，并有一定的腐蝕性，泡沫中殘留的酸對金屬材料有腐蝕作用。

　　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、巖棉彩鋼夾芯板巖棉彩鋼夾芯板，防火性能比較好，但巖棉彩鋼板不防水，遇火產生有毒物質，污染較大。

　　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、紙蜂窩彩鋼夾芯板紙蜂窩夾芯板可對廢棄物完全回收再利用，是聚苯板、聚氨脂、巖棉等材料的換代產品，廣泛應用于電子、醫院手術室、實驗室等潔凈工程領域，但防水效果差，較貴。

　　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、鋁峰窩夾芯板鋁蜂窩彩鋼夾芯板，它是由以鋁蜂窩芯板材，采用特制高強度膠水與彩鋼板復合，并由特制鋁合金龍骨支撐，經加溫、加壓、固化后而制成。與其它夾芯板相比，重量輕，平直度好，屬于綠色建材，但造價。

　　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)導程偏移預壓方式:(加大節距或縮小節距)特征:在螺母節距上作δ值的偏移來取代傳統雙螺母預壓方式，此方式較適用于中輕預壓，將預壓力設計在5%動負荷以下。2)拉伸預壓方式 特征:使用一過厚的預壓片將兩個螺母外張方式達到預壓之效果，此為HIWIN精密級滾珠絲杠常使用的方式。

　　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.
