展柜是展示商品的主要载体之一，展柜的分类也分为好几种，文物展柜就是展柜品种占有很大一部分的展柜，文物展柜顾名思义就是用来展览文物的，所以他需要的关注也是最多的，对于很多商家来说文物展柜的挑选也是极为麻烦的，因为他需要最细致的关注，今天我就来为各位讲述如何挑选合格的文物展柜。&苍产蝉辫;

　　众所周知文物以其历史的特殊性具有不可复制的特性，所以在博物馆展柜材料的选择上必须对文物没有损害。由于展柜和文物直接或间接的接触，假如展柜所用材料含有氯，硫或其它酸性成份，必然会对文物造成损害。它们通过接触文物或本身老化后释放出有害气体，包括二氧化硫，硫化氢，一氧化氮，二氧化氮，臭氧和挥发性有机酸类，挥发性醛类等对文物形成损害。所以展柜材料进行严格的筛选，选用通过测验或化学分析后的安全材料方可用于制作文物展柜。博物馆展柜的选材也已经淘汰了对文物会形成潜在损害的材料包括木头、油漆、胶粘剂、化学纤维纺织品等。普遍采用了不锈钢、铝合金和外表喷塑涂料钢板的安全材料。

 

　　出于对特殊文物保护的需要， 展柜操控温湿度应当具有良好的密封性，内部应当装置有温湿度显示仪器和操控湿度的设备。

 

　　文物展柜中照明设备也对对文物安全起到相当重要的作用，即应当运用无紫外线的冷光源射灯，每个灯的亮度都应当可在箱体中旋扭调整，光照点也应当可自由滚动调整。光导纤维照明可将灯火送入展柜照明方位，将发光热源放于较远方位，这有利于通风将发光热量排出柜外。

 

　　我国的珍惜文物应当传承下去，所以他们也需要最好的保护，对于各位商家在挑选展柜时务必要细致不能出一点差错。

Due to direct or indirect contact between the display cabinet and the cultural relics, if the materials used in the display cabinet contain chlorine, sulfur or other acidic components, the cultural relics will definitely be damaged. They cause damage to cultural relics by contacting them or releasing harmful gases after aging, including sulfur dioxide, hydrogen sulfide, nitric oxide, nitrogen dioxide, ozone, volatile organic acids, volatile aldehydes, etc. Therefore, the materials of the exhibition cabinet should be strictly screened, and the safe materials that pass the test or chemical analysis should be selected before they can be used to make the cultural relics exhibition cabinet. The selection of materials for museum display cabinets has also eliminated materials that may cause potential damage to cultural relics, including wood, paint, adhesives, chemical fiber textiles, etc. Safety materials such as stainless steel, aluminum alloy and plastic coated steel plate are widely used.

Due to the need for the protection of special cultural relics, the control of temperature and humidity in the display cabinet should have good sealing performance, and the interior should be equipped with temperature and humidity display instruments and humidity control equipment.

Lighting equipment in the cultural relics exhibition cabinet also plays a very important role in the safety of cultural relics, that is, cold light source spotlights without ultraviolet rays should be used, the brightness of each lamp should be able to be adjusted by twisting in the cabinet, and the lighting point should also be able to be freely adjusted by rolling. Optical fiber lighting can send lights into the lighting position of the display cabinet and place the luminous heat source in a far position, which is conducive to ventilation and discharge luminous heat out of the cabinet.

The precious cultural relics in our country should be passed on, so they also need the best protection. For each businessman, it is necessary to be careful and not make any mistakes when selecting display cabinets.
