     CCEWOOL ceramic blanket, also known for aluminum silicate blanket, is a new type of fire-resistant insulation materials in white and tidy size, with integrated fire resistance, heat separation and thermal insulation functions, containing no any binding agent.However, during usage, some ceramic blanket will have crack phenomenon, causing user’s confusion.Following we will introduce the causes of the cracks to avoid similar problems recurring.

     1. Fiber’s fineness modulus are too small, clay content is too high, causing cracks;

     2. Ceramic blanket mortar’s water absorption rate is high, cracks caused by winter frost;

     3. Ceramic blanket is uneven, due to inconsistent shrinkage stress;

     4. Cement ratio is too large and the label is too high, leading ceramic blanket shrinkage is too fast and big;

     5. Insufficient flexibility,small elongation index, causing low ceramic blanket deformation resistance.

     There are many kinds of reasons for the cracks of ceramic blanket, and it can solve the problem effectively only to find the specific reasons. Furthermore, users can prevent cost waste when meeting similar problems next time.Besides ceramic blanket, CCEWOOL series products also have ceramic fiber board,paper,textile,module and vacuum formed ceramic fiber.CCEWOOL can not only provide thermal insulation products, but also energy-saving solutions.
