：：WELCOME ：：

The roofing is the important component of the building, its quality quality influences industrial production and people's lives directly, so, what warm - keeping , heat insulation and waterproof result which improve the roofing on the basis of the thing that the rational technology of economy is feasible, it has that the scientific research has counted constructors and devoted to the technological difficult problem solved all the time to prevent roofing seepage. The question of roofing seepage is very outstanding . The statistics show , have completed 100 million all kinds of houses of square meter of mine every year on average in the cities and towns of our country in the past ten years, 1/3 presented seepage in that year in the base, Ministry of Construction indicated to 227 pieces of urban sample investigation of the whole country: New average seepage of building rate 60%, the national amount spent on roofing maintenance is up to 1,200 million yuan one year, the question of roofing seepage has already caused the various circles of society and paid attention to.

On-the-spot spraying hard quality foam(PUF) application technology among the project project adopt and connect the spraying skill of constructing in roofing in roofing, make liquid polyurethane up material spray at roof boarding directly , is it connect hard quality PUF and roofing basic unit of spraying form and has not spelt the waterproof heat preservation of the seam to make, in order to prevent the sunshine radiation and machinery from damaging and doing corresponding covering the surface antiabrasion layer. On-the-spot spraying is hard quality PUF and base he keeps the waterproof material warm to compare

The hard quality polyurethane PUF of on-the-spot spraying is for the use by all kinds of new or old industry and civil in all kinds of new or old industry and waterproof , warm - keeping in roofing of civil building. Spraying type hard quality PUF in structure, insulate against heat respect and energy-conserving respect have a lot of advantage. The spraying type hard quality PUF roof is compared with the asphalt felt roof, in case of emphasizing cost, there are the following ten major advantages on the polyurethane roof:

(1)The polyurethane is light, have very high intensity to the ratio by weight. New structure that roof can design light and handy, support structure province material of roof in this way can up to 20%. The old roof is renovated and only increased by 0 in each sq.ft.. Weight of 02 pounds.
(2)The key characteristic of the polyurethane is to insulate against heat, there are minimum heat conduction coefficient and supreme thermal resistance. That is to say , the a small amount of foam offers the greatest energy-conserving result. PUF is used on roofing influenced by weather as the thermal insulator, can reduce the hot impact , this kind hot to is it can make asphalt felt take place displacement is the main reason that the asphalt felt roof is damaged because of expanding with heat and contract with cold to bludgon into.
(3)Being roofing construction craft simple, little to environmental pollution, PUF does not is it is it melt and lead to the fact pollution to heat like asphalt felt roof pitch to want.
(4)PUF roofing can prevent from moisture horizontal to circulate in PUF, but asphalt felt can horizontal to circulate polyurethane be covered with wholly among layer. In foam after finishing fully packing and sealing , store in and spell the seam .
(6)PUF roofing can be made into the inclined plane directly, forms and drains off water the slope.
(7)PUF has very good sticking on all roof boarding.

(8)PUF roofing maintains the respect, benefits
　 some repair even more.
(9)PUF adapts to the structure of roofing like any.
(10)PUF roofing is flexible in design, the use is broad .

On-the-spot spraying hard quality for prevent sunshine radiation and machinery from buckle brokenly antiabrasion layer , PUF of polyurethane ,, need to cover antiabrasion layer of a layer on PUF. Can make the choice of the antiabrasion layer according to the concrete conditions of the project type project. In order to select the suitable antiabrasion layer for use , must consider all sorts of factors in an all-round way : (1)Environmental condition (2)The norm and flammability requiring (3)Life expectancy, and dry film thickness (4) machinery damage with stride trampling on wet rating (6 ) proper slope and ponding issue (7 ) it maintains getting convenient to be beautiful completely
Commonly used covering the surface antiabrasion layer has such non- elastic antiabrasion layers as pitch , SBS , APP ,etc. now, SPUA (the elastic coating of spraying polyurethane ) that the chemical research institute in the ocean produces is a kind of elastic antiabrasion layer , but the price is higher. No matter that kind of antiabrasion layer is only designed, constructed correctly, service life is up to about 20. The on-the-spot spraying PUF aspect is kept warm, the waterproof system is that nowadays the room becomes the most outstanding one in the system, his peculiar waterproof result of warm - keeping will bring the revolutionary leap to the organism department of the room.
The roofing keeps some instances of construction project warm
