The brief introduction of sandstone knowledge.Sandstone is a kind of natural rock,by the weathering of rocks denudation ten millions of years ago,it disintegrated debris or after the dissolution of water erosion,sedimentary rock in the bed.As a result of crustal movement,cemented by the pressure agent,and a series function of physical and chemistry,so that it is now for the formation of the sandstone mine.

The advantages of sandstone.

Sandstone is a kind of nonluminous pollution,radiation-free and high quality natural stone,it has no radioactive harm to the human body.It is moisturproof,antiskid, tasteless, non-radioactive, non-fading,warm in winter and cool in summer,sweet and elegant; comparsion with the timber,non-splitted, non-deformable, non-perishable, non-fading.

For material,it is a warm-toned decorative timber,simple but elegant,the coordination does not lose magnificenty and expensively;with the texture of stone,wood veins and the spectacular landscape pictures, rich colors, close to nature,simple and unsophisticated ,elegance.It is a unique style and be called “Li Shi”by human beings in a large number of stone.

The merits of the sandstone sculpture

The selection of sandstone with many advantages,it has the rich texture of playing space for sculpture,through the artificial carving,the products look reality and lifelikeness,demanding stritly on arts and crafts.The sandstone sculpture has artistry,durability and appreciate value of the products.In decoration,it has strong craft effect.This man-made sandstone with mould can not compare with it,the sculpture can persist forever fashion,with its elegant art life,making person feel its honourable by its wealth of sculpture shaped,the expression of design and artistic connotation.The products transmit light-music emotional appeal and lyric romance with natural and smooth writing suring as the painting of lines and multi-perspective into the composition of the place.In the form of emotional expression to a solemn,calm,the serious vigorous effect and imposing manner now and then.Its unique performance characteristics and rich sculpture style can not be substituted by other artistic form.Therefore,it is stylish,elegant and honourable.

The unique characteristics of the product.

At present,the sculpture on the market,we require strictly by interier decoration standard,making light delicacy and ultrathin products as possible as we can.The sculpture can not be the basis of the bottom thick smallest control in 6mm,greatly enhancing the space expressive force of the stone carving,exquist and ultrathin product,becoming the rare sandstone sculpture at the present market.The sandstone has many advantages as well as its brittle weakness,we use composite motherboard to enhance it,in order to increase their own strength and a sense of security.Though the enhancement of the product intensity,we also consider the simplify to the insatallation of the product,we can fixup the carving on the wall as long as with screw,the product can connect organically with carpentry fitment,the space of background molding can elaborate more perfect,it has overcome the stone material tradition installmene tedious and reduce the cost of installation.The house decorated can install sculpture on the wall directly without increasing other working procedure and paint.The product can be carved according to the design what users offered,in order to embody and demand users’taste of art and culture as well as individual character.

Sculpture and products: indoor and outdoor art stone sculpture,sandstone specification slab(floors and walls)of European ornament and sculpture as well as decorative package,window gate wrap.

With the improvement of people’s life standards and art taste,carving has been wildly applied in large-scale public buildings,the villa,the family,the decoration of the drinkery and guesthouse,garden landscape and city sculpture.

After stone material waxing to the influence of maintenance

There are stone installation personnel frequently to complain that:the effect of conservation was not obvious and it could not play an effective protector of stone as we expected.Some people even said that the stone could result in pathological changes happened after disposal of repellent,such as the stone material surface produces the yellow spot(it is mineralogical character itself or the max yellow spot frequently:At present,lagging material is kiesel material mostly,its yellow stain probability is small)or oil spot(In fact,it is water spot: the back fills in the mortar internal alkali or the bone material the salts infiltrates the human and deposits in the stone material interior).What material is stone repellent?How to do repellent treatments in order to exert its efficiency most effective?Which stage can process repellent treatments to confirm to the maximum economoc benefit? Which one kind of wet installment method to avoid a large number pathological changes factor into the internal stone to infract it?

At present,stone material industry faces the stone care problem,mostly has pathological change after the installment,and then some commerical disputes along with it.The installation personnel and the building owner are easiest to meet this kind of problem directly,therefore,when all aspects find the reason about the problem occurred,the emphases usually focus on whether builders have used the unqualfied bone material,stone setter whether or not to jerry-build,the stone construct method is appropriate or not.The supplier of raw stone material should not be considered,it is only thought that maybe the stone material quality has blemish at best.Certainly,the most directly factor about stone pathological changes is related to the method of stone construct and quality of protection.However,there are a number of pathological changes happened,its real factor is the job sequence of stone slab,in other words,sometimes the job sequence of stone slab can cause maintenance project’s barrier indirectly ,and sometimes it is more troublesome to solve follow-up problems than consumers imaged.In fact,the probability of stone material process inappropriately like this is very high,but it is always neglcted.So, we contrapose the working procedure of general stone material processing factory cause the problem easily,we have to analyze its advantages and disadvantages. In addition,we recommended that the stone processing factory consider to add the working procedure about stone material protection into the standard process scheme,or consider to build an indepent and professional stone care factory,carry on improving the stone protect project.

Stone is a natural building materials, because its surface in the stone material production process variation factor creates the lines on face fine lace (commonly known as chicken feet grain) and the gloss is not satisfactory, therefore, manufacturers often use a variety of ways to enhance the stone's surface gloss, to reduce the small lines and filament of the small stone on the surface.

At present,most frequently method is to get wax on the surface of stone skived on the domestic market.This can not only increase the surface gloss of stone product,but also reduce the chicken feet grain of the stone surface.This way is both convenience and economy to the stone material factory.However ,it has possibility to cause a great deal of trouble to consumers and the workers of installment, its primary cause is:

The wax is one kind of superficial protection material, after its cover in the stone material surface, the stone material surface original wool pore and the lines on face can block,therefore,stone setters of installment or stone protecters ,if they want to carry on the stone material protection project, the stone material surface wax has existed instead is the protection infiltrates the human stone material interior biggest barrier,leading to the protective layer only to exist in the surface is unable to seep to the stone material surface below, possibly has the danger which the protection defeat and the following pathological change occurs to increase, in this case by soft bottom wet technology paving ground stone material time, lays down the stone material is frequently not the compact material (for example the tinted granite and so on) As the matter stands, it is not nearly avoided that the topicality water stain pathological change happened after the basis watery.In addition,after waxing the stone ,there are many expose in the air and the sunlight for a long time,leading to the etiolation phenomenon easily.

It may be the primary factor of the yellow stain which stone material happened.
