Abstract
The invention relates to the technical field of foaming polyurethane, particularly to a foaming polyurethane spraying device and an application method thereof. The foaming polyurethane spraying device comprises a liquid tank I and a liquid tank II, MDI (diphenylmethane diisocyanate) and polyether polyol are respectively filled in the liquid tank I and the liquid tank II, the top of the liquid tank I and the top of the liquid tank II are provided with a valve respectively, the liquid tank I and the liquid tank II are connected with a spray gun through a hose respectively, the spray gun is provided with a nozzle in the shape of V or O. The construction method thereof comprises the steps of opening the valves: slowly rotating the valves on the tops of the liquid tank I and the liquid tank II until the valves are completely opened; installing the nozzle: installing the nozzle onto the spray gun and checking whether the hoses leaks; performing spraying: tightly holding the handle of the spray gun to achieve spraying.
Description
Technical field
The present invention relates to polyurathamc technical field, specifically a kind of polyurathamc spray equipment and construction method thereof.
Background technology
In construction, building gap and thermal insulation around, electrical equipment, the gap of pipeline, the shape cavity of curtain wall all needs to fill, to reach thermal insulation, waterproof, fire-retardant object, conventional method is to adopt air compressor machine to fill building gap at present, or adopts glue beating apparatus to fill, and construction is got up very convenient, and filling effect is bad, traditional mineral wool, polyurethane foam agent perlite are filled and are had the following disadvantages:
Mineral wool heat conductivity is high, and easily water suction, has condensation phenomenon, and the equipment of the skin that needs protection during construction, is not suitable for built building, and because compression/sedimentation meeting reduces effective thickness, breed bacteria and mite, cause respiratory disease.
Adopt freon polyurathamc, harm atmosphere.
Perlite heat conductivity is high, through moisture or idling carry that can cause subsides drops, can grow mould, cannot construct winter.
Therefore; in order to overcome, the deficiency of above-mentioned technology is designed insulation, antifreeze, soundproof effect is obvious; and avoid poisonous and harmful substance, protection operating personnel's personal safety and construct simple and convenient efficient a kind of polyurathamc spray equipment and construction method, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of polyurathamc spray equipment and construction method thereof, its device is simple, easy to operate, and energy-saving safe, high-efficiency environment friendly guarantee operating personnel's personal safety, have extraordinary practical value.
The technical solution adopted for the present invention to solve the technical problems is: a kind of polyurathamc spray equipment, comprise liquid tank first and liquid tank second, in described liquid tank first and liquid tank second, MDI and PPG are housed respectively, liquid tank first and liquid tank second top are provided with valve, liquid tank first is connected with spray gun by flexible pipe respectively with liquid tank second, and nozzle is installed on spray gun.
Further, described nozzle is shaped as V-type or O type.
Further, a kind of construction method of polyurathamc spray equipment, comprises following steps:
(1) open valve: slowly the valve on turn liquid tank first and liquid tank second top is until open completely;
(2) nozzle is installed: nozzle is installed on spray gun, check whether flexible pipe has seepage;
(3) spraying: the spray gun handle of holding with a firm grip is realized and being sprayed.
The invention has the beneficial effects as follows:
1, the elastic foam of water base foaming does not discharge poison gas in fire, and it is harmless nontoxic eco-friendly spary coating type insulation material, for insulation, antifreeze, sound insulation, interface void waterproof etc.
2, the harmful freon of Construction on Environment or fluorochlorohydrocarbon, as blowing agent, only do not adopt water as blowing agent, prevention global warming issue.
3, the double-component heat insulating material of this spary coating type 100 times of volumes of as many as that can expand, have air-tightness completely, and lower than the heat conductivity of 0.040W/mK, heat loss are down to minimum.
4, outstanding easy act, moment foaming, low-temp foaming, faster than other product constructions, construct extremely convenient, use plastic spray gun and nozzle installation system.
5, range of application is very extensive, can be for building gap and thermal insulation around, electrical equipment, pipeline blind, esconson is filled, the filling of internal and external building materials connecting portion, thermal insulation during expansion balcony, supply equipment or metrical instrument prevent from freezing brokenly, when house sidewall reinforcing is adiabatic, between domestic floor, prevent noise pollution, heat-insulating material is damaged, stone material, curtain wall, electric, the equipment maintenance that comes off, the double-jacket of filling food tank, fill boiler water storage tank, the filling of bath base, the filling of heat exchanger inside, be applicable to the various insulations that need, cold insulation, the product manufacture view of sound insulation.
6, sound-absorbing, air conditioning characteristic have benefited from semi open model eucaryotic cell structure, and it has very high air-tightness and fabulous sound absorbing power, make it can completely cut off noise completely.In addition,, due to its air conditioning characteristic, it is a kind of insulation material that surface sweating problem can not occur.
7, durability is unlike common foaming with freon, and it can be because of the release of Freon gas along with the time changes.Its elastic construction can adapt to crack and the vibrations of building.It has the permanent construction time limit, is exposed to lower of ultraviolet ray and fades, and deformation or contraction can not occur.
8, energy-conservation have perfect air-tightness and a thermal insulation, and continuity jet printing type heat-insulating material is economized the energy of 30-40% than board type insulant energy more piece, and economy is strong.
