Difference is unable to satisfy the requirement as wall heat insulation material.Although occurring that nothing is fixed using suture way in the prior art
Machine thermal insulation material to enhance the technical solution of its tensile strength, but only with the fixed inorganic heat insulation material of suture in delivery or
In work progress, it is easy to which there is a situation where off-lines, and the practical tensile strength of its own improves little as a result,.
2, inorganic heat insulation material water absorption rate is higher.The hygroscopic expansion of inorganic heat insulation material causes material deformation that can make wall
External thermal insulation part generates hollowing, cracking even falls off, and generates security risk;When inorganic heat insulation material water suction is excessively high, can also lead
It causes thermal coefficient sharply to increase, reduces the thermal insulation property of entire wall.
3, using single inorganic heat insulation material, thermal insulation property is determined by the thickness of insulation board, to reach a certain heat insulating ability
When energy, the thickness of inorganic heat insulation material can only be increased, the thickness of inorganic heat insulation material can not be adjusted flexibly to meet design requirement.
4, impurity is more in inorganic heat insulation material, causes that the inorganic material slag ball produced is more, fiber is tiny easy to fall off, does
It will itch with to construction personnel, increase difficulty of construction, improve construction cost;Dust when in addition constructing is to construction personnel
Damage it is also very big.
