作者： | 时间：2026-06-01 09:41:35
工艺特点：采用湿法成型制芯 + 高速多轴圆编机外层包覆，以2×2或3×3绞编结构编织陶瓷纤维纱（含量>85%）与增强丝（无碱玻璃纤维或316L不锈钢丝，占比10–15%）；编织密度控制在18–22针/厘米，形成致密圆形截面；工艺兼容分类温度1260℃（标准型），成品容重约500–750 kg/m³，直径通常5–100 mm（>50 mm须含金属增强）。
功能优势：陶瓷纤维圆编具有耐高温、低导热率、良好的弹性回复性和抗压缩性等特点。在高温密封应用中，其圆形截面能与密封槽实现更为贴合的接触，提高密封效果。此外，圆编绳还具有一定的隔声和减振功能，在工业设备中亦有减震隔热的复合应用
规格范围：陶瓷纤维圆编的直径范围通常在3mm至100mm之间，可根据用户要求定制特殊规格，产品长度可按需裁切或以卷装供货。耐温等级根据纤维成分从900°C至1260°C不等，满足不同温度工况的使用需求。
陶瓷纤维圆编作为一种多功能的高温密封与防护材料，广泛用于锅炉门、炉窑膨胀缝、机泵阀盘根等高温密封与绝热场景，工艺上通过编织密度与增强层配置实现“密封性+柔韧性+耐温”的平衡，但本身脆性大、不耐冲刷，需配合密封胶安装并预留10–15%压缩量。

Ceramic fiber round braid, also known as ceramic fiber braided rope, is a round cross-section rope-shaped product made from ceramic fiber yarns as the primary raw material, woven by a circular braiding machine through cross-interlacing of multiple yarn strands. Based on the braiding structure, it can be divided into hollow round braid and solid round braid. Some products also have ceramic fiber bulk or high-temperature-resistant core ropes filled inside to enhance cross-sectional density and sealing performance.
Process Characteristics: The product is manufactured using a wet-laid core forming process combined with high-speed multi-axis circular braiding for outer layer wrapping, in a 2×2 or 3×3 braided structure interweaving ceramic fiber yarn (content >85%) with reinforcing filaments (alkali-free glass fiber or 316L stainless steel wire, accounting for 10–15%). The braiding density is controlled at 18–22 stitches per centimeter, forming a dense circular cross-section. The process is compatible with a classification temperature of 1260°C (standard grade). The finished product has a bulk density of approximately 500–750 kg/m³, with diameters typically ranging from 5 to 100 mm (>50 mm must include metal reinforcement).
Functional Advantages: Ceramic fiber round braid is characterized by high-temperature resistance, low thermal conductivity, good elastic recovery, and compressive resistance. In high-temperature sealing applications, its circular cross-section can achieve a more conforming contact with sealing grooves, improving sealing effectiveness. In addition, the braided rope also has certain sound insulation and vibration damping functions, finding composite applications for shock absorption and thermal insulation in industrial equipment.
Specification Range: The diameter of ceramic fiber round braid typically ranges from 3 mm to 100 mm, with special specifications customizable according to user requirements. The product length can be cut to required dimensions or supplied in rolls. Temperature ratings range from 900°C to 1260°C depending on the fiber composition, meeting the usage requirements of different temperature operating conditions.
As a versatile high-temperature sealing and protective material, ceramic fiber braided rope is widely used in high-temperature sealing and thermal insulation applications such as boiler doors, kiln expansion joints, and pump/valve packing glands. From a process standpoint, it achieves a balance of sealing performance, flexibility, and temperature resistance through controlled braiding density and reinforced layer configuration. However, the material itself is inherently brittle and has poor erosion resistance, requiring installation with sealing compound and a reserved compression allowance of 10–15%.
