Description

Heat floor array air drain

Technical field

The utility model belongs to wood flooring production technical field, relates in particular to one and heats floor array air drain.

Background technology

China is vast in territory, and wherein northern area winter temperature is extremely low, and the areas such as northwest, Central China, East China make a clear distinction between the four seasons again every winter its temperature also to subzero; In order to solve warming problem, general employing central heating, but central heating engineering because energy consumption is large, to waste the problem such as large, seriously polluted be to obtain large-scale promotion and use, cause central heating mode only to cover some extremely cold areas of northern area and be confined to some metropolis, and at all cannot the heating of relatively northern small and medium-sized cities and vast other cold districts in winter.Along with the improving constantly of living standards of the people and quality of life, the frequent generation of extreme weather in addition, having a strong impact on these regional people's quality of life in winter, special old man and child, the policy contradictory problems not heating about heating south, the north at present also grows in intensity! Along with China advances the policy of building energy conservation and each door type heating, rapidly, the promulgation of all kinds of supportive policies has promoted the extensive use of this technology to the development of low-temperature ground heating technology especially greatly.The raising of domestic resident living level and growing housing need drive the prosperity of real estate industry, huge real-estate market, particularly there is no the area, the Yangtze river basin of central heating as main heating consumption demand, for ground heating industry has been brought infinite commercial opportunities.Heating region is expanding simultaneously: covered to the southern area such as East China, southwest just rapidly by traditional north, covered to small and medium-sized cities and vast small towns by big and medium-sized cities.Heating system is changing: electric floor heating, as a kind of environmental protection heating system easily, is expanding rapidly the share in floor heating market again.China's ground radiation heating market will have exceeded hundred billion yuan in the end of the year 2012, wherein the low temperature hot water radiation heating of technology maturation and fin heating approximately occupy the market share of 70% left and right, though electric heating is in the starting stage, but it is easy for installation, do not take up space, can point family heating, facilitate every advantage of old room heating transformation, make electric floor heating also occupy the market share of 25% left and right, and keep continuing the trend of rising.

Along with wood flooring is accepted by masses, heating timber floor also slowly buds out into popularity, but in heating floor process, there are the serious quality problems such as cracking and directly cause product rejection, trace it to its cause be upper and lower two substrates under HTHP take moisture contained in base material as heat transfer channel, transferring heat is to resin, resin is cured after being heated, but fully curing by resin in order to ensure sufficient heat, therefore just must there be enough heats must meet hot pressing time, but the moisture in hot pressing in base material is vaporization at the same time also, under high pressure conditions, it is intact, but a large amount of water vapours in the middle part of base material in a flash of release also can discharge from the weakest region of this intensity of base material, in the process discharging, will directly cause base material cracking to form waste product, existing way is exactly that sawing becomes hot pressing after small-sized, this way cannot form again batch production, just there are the serious quality problems such as cracking and directly cause product rejection in result, make cannot realize the suitability for industrialized production of effective batch at all.

Utility model content

The purpose of this utility model is to propose one and heats floor array air drain, by the processing to substrate, solves the problem running in current production link.

To achieve these goals, the technical scheme adopting is: one heats floor array air drain, feature is heating in the process of floor, the transverse row air drain arranging at substrate length direction approximately 1/2 place, the infrabasal plate exhaust notch of infrabasal plate upward, the infrabasal plate air discharge duct mouth down of upper substrate, upper substrate air discharge duct aligns with infrabasal plate air discharge duct, centre arranges intermediate layer, and intermediate layer is the combination of lower gum dipped paper, conductive metal sheet, wiring terminal, far infrared nano carbon fiber heating paper and upper gum dipped paper.The manufacturing step that heats floor array air drain is: 1. substrate groove milling, the substrate of assembly divides upper and lower two, on upper and lower two 6mm substrates take edges of boards as datum/anchor point, engrave milling equipment by the blank requirement specification use of plate variously, at translot of length direction approximately 1/2 place's pre-milling, this translot is also the steam vent reserved at hot pressing, stacks neatly for subsequent use; 2. blanket assembly, taken milling translot and drilled substrate, one of groove milling faces up, lay successively lower gum dipped paper, conductive metal sheet, wiring terminal, far infrared nano carbon fiber heating paper and upper gum dipped paper, take a milling and cross the 6mm substrate of translot, transverse groove covers downwards topmost, will notice that the translot notch that will align in long limit, upper and lower two 6mm substrates are engraved milling will align when covering; 3. blanket laminating, employing equipment is 2800 tons of press short-cycle hot-pressing machines or 1800 tons of multi-daylight presses, all uses up and down plane steel plate, short period 2800 tons of press pressure 13-14Mpa; 1800 tons of multi-daylight press pressure 19-21Mpa, 140～145 ℃ of temperature, time 360～400S; 4. blanket health: every 60 of blanket is a stacking, and when health is deposited, stacking height can not exceed 3 layers, must retain heat-dissipating space more than 10cm between buttress layer; Whole blanket needs conditioned time just will protect more than 5 days, guarantees that blanket is fully cooling.

The utility model has the advantages that: we have taked large specification base material according to heating the regular processing of floor trimmed size, steam vent being set, make evenly exhaust in hot pressing, reach and met resin solidification requirement, moisture in base material is progressively discharged uniformly, the product quality of producing reaches requirement thoroughly have been avoided again producing because water vapour discharges the waste product causing, thereby has finally reached effective mass, suitability for industrialized production.
