摘要： PROBLEM TO BE SOLVED: To enable an efficient crystallization and drying of polymer granule to be carried out by a method wherein inert gas medium is supplied into a specified region of a polymer granule accumulation floor in a system in which polymer granules are crystallized and dried within an outer shell formed with a vertical processing chamber, and shrunk into solid state as required. SOLUTION: Polymer granular particles are loaded from a connecting section 1 into a vertical device 2 and filled up to a height level of 500mm above an inert gas inlet 4, thereafter the inert gas medium supplied from the connecting section 4 heats the polymer granular particles together with inert gas medium fed from a connecting section 5 so as to crystalize the granular particles. At this time, forming of the condensed material is prevented by supplying medium from the connecting section 4 in a form of inert gas pulsation flow, the supplied inert gas flow passes from an outlet port 6 through a gas refining system and a heat exchanger system and refined there. The crystallized polymer granular particles are taken out of a connecting section 7. Then, a processing chamber 3 which can be cooled or heated is frushed with inert gas through a connecting section 5 so as to remove discharged volatile substance.

摘要： PROBLEM TO BE SOLVED: To recycle it as a single material system by using a windable heat insulating material which contains a synthetic fiber material and whose heat conductivity determined according to DIN 4108 Part 1 is not more than a specific value and which has fire resistant behavior of DIN 4102 Part 1 corresponding to a kind of building material B1. SOLUTION: Synthetic fiber is composed of load resistant fiber and binding fiber made of polyester, preferably, polyethylene telephthalate, and the binding fiber exists at least in a part of a surface of polyester having a melting point lower than a melting point of the load resistant fiber. In this heat insulating material, a thickness is 30 to 200mm, and a Metsuke unit is 400 to 300g/m , and density is 15 to 50kg/m . Therefore, a heat insulating material whose heat conductivity determined according to DIN 4108 Part 1 is not more than 0.04W/m*K, and which has fire resistant behavior (DIN 4102 Part 1) corresponding to a kind of building material B1 and contains a single material system of a synthetic fiber material and can be recycled, can be obtained.
