“I want to use 1000 ° C resistant cloth. Your customer service said that there are two kinds of cloth that can meet the temperature requirements: ceramic fiber cloth and high silica cloth. Which one do I use? How do I know the difference between two kinds of cloth? You introduce me! ” Let our professional technicians tell you!
In fact, to recommend suitable heat-resistant and thermal insulation products to customers, we must recommend them in combination with the actual use of customers. Customer service must use the problem to remind you to describe the application scenario, so as to recommend the most appropriate products according to the application. Some customers are anxious. Some customers don’t know the application very well. When they submit a purchase plan, they just ask for the product name. They also hope that everyone can calm down. After all, finding the right thing is everyone’s consistent goal.
1、 Product introduction
Ceramic fiber cloth: ceramic fiber cloth is woven from heat-resistant alloy wire or alkali free glass yarn reinforced swing wire ceramic fiber yarn. Ceramic fiber cloth has high strength, good flexibility and strong machinability. It not only has high-temperature heat insulation performance, but also has the flexibility of ordinary textiles. It can process fireproof clothes, fire blankets, thermal insulation sleeves and other industrial and civil fire-resistant and thermal insulation products.
High silica cloth: high silica cloth refractory fiber is a kind of high temperature resistant inorganic fiber. Its silica (SiO2) content is higher than 96% and its softening point is close to 1700 ° C. It is used for a long time at 1000 ° C. It can work for 10 minutes at 1450 ° C and 15 seconds at 1600 ° C. High silica refractory fiber cloth has the characteristics of high strength, easy processing and wide application. It is used as high temperature resistance, ablation resistance, heat insulation and thermal insulation materials.
Difference 1: ceramic fiber cloth is short fiber, which needs to be strengthened and toughened by other objects, generally glass fiber and stainless steel wire; High silica cloth is a long fiber and does not need to be toughened by other objects.
Difference 2: the short-time temperature resistance of high silicon oxide cloth is higher. After testing, the instantaneous temperature resistance of high silicon oxide cloth samples provided by Shandong redun high temperature materials Co., Ltd. can reach 1600 ° C; The temperature resistance of ceramic fiber cloth is 1260 ° C.
Difference 3: the treated high silica cloth has no organic residue; Ceramic fiber cloth has a certain proportion of organic matter.
Difference 4: the long-term service temperature of ceramic fiber cloth is 0 ° c-1000 ° C; Long term service temperature of high silica cloth > = 1000 ° C.
Difference 5: the surface of ceramic fiber cloth is rough; The surface of high silica cloth is smooth.
Difference 6: ceramic fiber cloth is the thinnest 2mm and the thickest 5mm; The maximum thickness of high silica cloth is 0.24mm and 1.3mm.
