Embodiment Construction

[0025] according to Picture 1-1 3. Describe in detail the specific structure and working conditions of the present invention. The plastic heat insulating pad is an integral gasket with compartments, including a heat insulating surface 1 and a supporting surface 4 , and the heat insulating surface 1 is integrated with the supporting surface 4 through a connecting body 2 with compartments 3 . It can be made into an I-type structure according to actual needs (such as Figure 1-3 shown) or type II structure (such as Figure 4-5 shown). The plastic insulation pad is made of flame-retardant hard plastic, such as hard polyvinyl chloride (PVC-U) and other materials. After mixing, it is extruded by the plastic extruder 5, and is shaped and cooled by a specific mold to become a spacer. Overall padding. This embodiment only describes a specific mold used for processing the I-type structural plastic insulation pad. Used plastics extruder 5 selects commercially available conical twin...

Abstract

The present invention relates to thermal insulaitng plastic cushion and its production process. The plastic cushion includes thermal insulating plane and support plane connected via a connecting part. It is produced with non-inflammable hard plastic and through the process of blending, extruding, forming and cooling in a special mold comprising hot extruding section, vacuum setting section and water cooling section, and cutting in set length. It has the advantages of heat insulation, antiflaming, chemical corrosion resistance, low cost and long service life.

Description

technical field [0001] The invention relates to a plastic product and a processing method thereof, in particular to a plastic insulation pad used in central air-conditioning system engineering of various construction projects and a processing method thereof. technical background [0002] At present, in the construction of central air-conditioning system projects of various construction projects, according to the requirements of the national standard GB50243-2002 "Code for Acceptance of Construction Quality of Ventilation and Air-Conditioning Engineering", the installation of steel pipes should meet the following requirements, that is, the cold and hot water pipes of air-conditioning And between the air duct pipe and the support and hanger, there should be a heat-insulating liner (non-combustible, flame-retardant hard heat-insulation material or anti-corrosion treated wood liner whose bearing strength can meet the weight of the pipe). For a long time, for the installation bet...
