【产品名称】 细孔硅胶(A型硅胶)
【性状】细孔硅胶分细孔球形硅胶和细孔块状硅胶两种。细孔球形硅胶外观为无色或微黄色的透明或半透明球形颗粒,细孔块状硅胶为无色或微黄色半透明玻璃状的不规则颗粒。细孔硅胶又叫A型硅胶。【用途】主要用于干燥、防潮,也可用作催化剂载体、吸附剂、分离剂、以及变压吸附等。广泛用于仪器仪表、电器设备、药品、食品、纺织品及其他各种包装物品中控制环境的相对湿度,防止物品受潮,霉变和锈蚀。因其具有堆积密度高和低湿度下吸湿效果明显的特点,可以用作空气净化剂。在海运途中也有广泛的应用,因为货物在运输过程中常因温度大而受潮变质,用该产品可有效的去湿防潮,使货物的质量得到保障。【基本质量参数】

Narrow spherical silica gel is colorless or slightly yellow transparent or semitransparent granular in substance, narrow lumpy silica gel is colorless or slightly yellow transparent or semitransparent Irregular granular in substance. Fine-pored silica gel is also called Type-A silica gel.【Use】Mainly used for drying and moisture proof, may also be used as catalyst carriers, adsorbents, separators and variable-pressure adsorbents, etc.Widely used to protecting instruments, electronic equipment, medicine, foodstuff, textile products and other packed material from moisture. It can prevent items from moisture, mildewing and rusting. Because of its high packing density and effective moisture absorption under low humidity, it is used for the purification of air. Also it is often used in ocean shipment to keep goods from the damage caused by excessive humidity.【Technical Data】Average pore diameter: 2.0-3.0nm, Surface area: 650-800m2/g, Pore volume:0.35-0.45ml/g, Specific heat:0.92KJ/kg.℃,Thermal conductivity: 0.63 KJ/m.Hr.℃.ItemSpecificationsTypical DateSuperior classFirst classQualifiied classAdsorption capacityRH=20%12min10min8min11minRH=50%26min24min20min25minRH=90%36min32min30min37minLoss on heating,%≤2564PH value4--84--84--84Specific resistance,Ω.㎝3000min3000min3000min4000minSilica %98.5min98min98min98.5minBulk density, g/lNANANA780【Size】narrow spherical silica gel:0.5-1.5mm、1-2mm、1-3mm、2-4mm、3-5mm、4-8mmnarrow lumpy silica gel: 0.5-1mm、0.5-2mm、1.5-4mm【Package】25kg PP bag,25kg compound bag,500kg/800kg contain bag.【Note】The moisture content, packing and size can be adjusted according to customer’s different requirements.
