Description
【発明の詳細な説明】 本発明は防熱材エレメントの改良にかかわる。[Detailed description of the invention] The present invention relates to improvements in thermal insulation elements.
抑々、従来、外側防熱を行なう低温液化ガス貯槽な・ど
においては、その構成にポリウレタンフォーム、塩ビフ
オームなど有機材料発泡体、パーライトなどの粉東泡ガ
ラスが使用されている。Conventionally, in low-temperature liquefied gas storage tanks that provide external heat insulation, organic material foams such as polyurethane foam and PVC foam, and powdered foam glass such as perlite have been used for their construction.
上述の中にあって、先づ、有機材料発泡体は熱伝導率の
面では極く良好なるも１石油を原料とすることのため、
高価格に失する。之に反しパーライトは無機材料のため
低価格なるも、粉末状なるため沈降して熱伝導率が大き
くなる不具合を惹起し、万一の容器破壊時には、液化ガ
スが触れて防熱材は濡れ、ために液化ガスが急激な蒸発
をするという欠点がある。Among the above, first of all, organic material foams have extremely good thermal conductivity, but because they are made from petroleum,
Lose in high prices. On the other hand, perlite is an inorganic material and is therefore cheaper, but since it is in a powder form, it settles and has a high thermal conductivity.If the container were to break, the liquefied gas would come in contact with it and the heat insulating material would get wet and accumulate. The disadvantage is that the liquefied gas evaporates rapidly.
又、泡ガラスなどは耐圧力の点にも難点かあるを免れ得
ない。Furthermore, foamed glass and the like inevitably have some drawbacks in terms of pressure resistance.
そこで、絣究の結果１１本発明は上述の諸欠陥を解消し

を提供しようとするものである。Therefore, as a result of Kasuri research 11, the present invention aims to eliminate the above-mentioned defects and provide a heat insulating material element that makes pearlite heat insulating more effective and has a lower thermal conductivity. It is.
以下第１図によって本発明の構造を述べる。The structure of the present invention will be described below with reference to FIG.

It is a vessel. The desirable morphological conditions are (a) A thin, elastic, closed spherical or polyhedral shape, or a synthetic resin shell with a mouth and optionally expandable closed cells, and the spherical shape is polyhedral. thing.
２は弾性ゴムなどでできたフロンガス流入、吸出しのた

た後に例えばパーライトのような無機質の防熱材料３を
弗素系炭化水素（例えばフロン）とともに押し込み（例
えば注射器をもって）大気圧よりやや低くしておく。2 is a seat made of elastic rubber or the like for inflowing and sucking out freon gas. Using this seat, after removing the air inside, an inorganic heat-insulating material 3, such as pearlite, is pushed in together with a fluorine-based hydrocarbon (for example, fluorocarbon) (for example, with a syringe) to make the pressure slightly lower than atmospheric pressure.
そして、容器内部は、上記パーライト粉末３とその間隙
部に充填されたフロン４により構成されておる。The inside of the container is composed of the pearlite powder 3 and Freon 4 filled in the gap between the pearlite powders 3 and 3.
上述０ような構成をもつ１本発明の作用を述べる。The operation of the present invention having the above-mentioned configuration will be described.
こうして、防熱材エレメントを多数、必要な防熱区画内

防熱材エレメントの外壁部１を密着させて、これによっ
て防熱構造の作用を果さしめることもできる。In this way, a large number of heat insulating material elements are packed in the required heat insulating section in the most dense state to form a heat insulating layer. In addition, different from this usage state, the pressure is reduced in the outer cavity of the heat insulating material element, and the heat insulating material element is expanded, thereby bringing the outer wall portions 1 of the heat insulating material elements into close contact with each other, thereby forming a heat insulating material. It can also function as a structure.
又、空隙部に別のパーライト粉末を入れ、防熱材エレメ

、もって防熱の作用をすることもできる。Alternatively, another pearlite powder can be placed in the cavity, the pressure is reduced in the same way as inside the heat insulating material element, and Freon is injected instead of air, thereby providing a heat insulating effect.
以上のように種々防熱構造を形成し、もって防熱作用を

たこれをその侭再び充填することもできる。As mentioned above, various heat insulation structures can be formed to achieve heat insulation effects, but by using the heat insulation material element of the present invention, (1) the heat insulation material element becomes the same as one closed cell and becomes independent. Because of this, the precipitation of pearlite occurs only inside the element, and this is extremely small and can be ignored. (2) The outside of the pearlite powder is the elastic body of the plastic container and is liquid-tight, so even if the container were to break and become wet, the increase in evaporation would not be as significant. Also, there is no damage to the heat shield layer. (3
) When inspecting the insulation compartment, the insulation element can be evacuated out of the thread by means of a suitable pneumatic transport method, and can be filled again afterwards.
という諸効果をあげることができる。The following effects can be achieved.
