Abstract
The utility model relates to a freezing point ware is applicable to and is used as well low temperature examination and measuring heat preservation device in laboratory or laboratory. The freezing point device is mainly characterized in that the upper cover and the cylinder body are at least composed of an inner layer, a middle layer and an outer layer of structural materials, the bonding material which combines the inner layer, the middle layer and the outer layer into a whole is double-component polyurethane foam plastic, and the good bonding characteristic of the double-component polyurethane foam plastic and polyester resin glass fiber reinforced plastics is utilized to manufacture the complete freezing point device. The utility model discloses overcome easily producing among the prior art better and burst, be afraid of collision and the little scheduling problem of volume.
Description
The utility model belongs to insulation articles for use field, the low temperature calibrating attemperator (Freezing point device) used with measurement in being specifically related to be used as in the test cell.
Be used for the low temperature calibrating at present in the test cell and be wide-mouth glass inner bag vacuum bottle formula with the Freezing point device of measuring, the advantage of this kind Freezing point device is that heat-insulating property is better, but be used for resistance to heat mensuration, normal steep variation or misoperation because of temperature produces the explosion phenomenon in the triple point measurement process of water, cause personal injury accidents sometimes, make the operator forbidding.In addition, this wide-mouth glass inner bag type Freezing point device is limited to the restriction of glass inner bag manufacturing technology, and general volume is less, can not satisfy existing middle cold-test chamber will have big volume to Freezing point device requirement.
The purpose of this utility model provides a kind of heat-insulating property and is better than the wide-mouth glass inner bag, and volume can be made into all size, can not produce explosion and safe and reliable middle low temperature test Freezing point device.
For finishing the technical scheme that above-mentioned purpose adopts be, the utility model removes continues to use existing Freezing point device loam cake of easy realization in manufacturing process, go to the bottom, outside outer barrel and the inner-tube structure form, the crucial ectonexine that also comprises in the loam cake, barrel and inner bag have adopted and a kind ofly have been shaped simple and with the dual-component polyurethane foamed plastic alkide resin glass-reinforced plastic material of secure bond power are arranged, in addition, in the outer wall of stack shell and the interlayer between the inner bag (middle level), be perfused with one deck and can make the dual-component polyurethane foamed plastic that warm material can be made structural materials again, loam cake is at least also by interior in addition, in, outer three-decker is synthetic, and the filling of dual-component polyurethane foamed plastic is also adopted in the middle level.
The utility model is compared with existing wide-mouth glass inner bag Freezing point device and is had the following advantages:
1, heat-insulating property is better than wide-mouth glass inner bag formula Freezing point device;
2, under middle cryogenic conditions, but test temperature drastic change can not produce explosion, the collision when not being afraid of operation, and use is perfectly safe;
3, make simply, its volume can be made plurality of specifications according to the test cell needs.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the cutaway view of the utility model Freezing point device.
Referring to Fig. 1, loam cake is by outer 1, middle level 2, and internal layer 3 and adhesion layer 4 are formed, and be outer 1, and internal layer 3 is formed through mold pressing by the alkide resin glass-felt plastic.Cylindrical shell is by inner bag 5, interlayer 6 barrels 7 and backing 8 are formed, and barrel 7 forms through rolling, middle level 2, interlayer 6 adopts the filling of dual-component polyurethane foamed plastic, reperfusion mode is adopted in filling, utilizes the not compound preceding liquid characteristic of dual-component polyurethane to carry out, and its manufacture method is earlier with A group, B group polyurethane mixing and stirring, be inverted loam cake and cylindrical shell then, raise internal layer 3 and backing 8, the dual-component polyurethane after stirring is quantitatively poured into middle level and interlayer 6, cover internal layer 3 and backing 8.At it voluntarily in the foaming process, the secure bond characteristic by dual-component polyurethane and alkide resin glass-felt plastic forms the firm structural wood bed of material of one deck, thereby constitutes complete loam cake and cylindrical shell.For air-tightness and the heat retaining property that strengthens loam cake and cylindrical shell, be provided with adhesion layer 4 at the convex surface of loam cake internal layer 3, adhesion layer 4 is the closed pore flexible polyurethane foam, and by 602 glue it is bonded on the convex surface of internal layer 3.Utilize the formability and the dual-component polyurethane of alkide resin glass-felt plastic that the alkide resin glass-felt plastic is had good cohesiveness, shell of the present utility model and inner bag can be made multiple shape and specification to the different needs of Freezing point device according to test cell (laboratory), the content that the utility model comprised be not limited to for embodiment.
Claims (3)
1, a kind of Freezing point device of being made up of loam cake and cylindrical shell is characterized in that loam cake and stack shell are synthetic by interior, domestic and abroad three-decker material at least.
2, Freezing point device according to claim 1, it is characterized in that the ectonexine in the loam cake, backing and inner bag adopt repressed the forming of alkide resin glass-felt plastic, and barrel adopts the alkide resin glass-felt plastic to form through rolling, and middle level (interlayer) adopts the filling of dual-component polyurethane foamed plastic.
3, Freezing point device according to claim 1 and 2, it is characterized in that with the bonding material that interior, domestic and abroad three-layered node is integrated be the dual-component polyurethane foamed plastic, by in its natural foaming, constituting complete loam cake and cylindrical shell with the secure bond of alkide resin glass-felt plastic.
