Wonderglas GC weather resisitance FRP

The answer:FRP sheeting has independent mature fastening system,when using in the areas where typhoons are common and the areas where the wind pressure is big,can increase the thickness of the FRP sheeting,reduce the space of FRP sheeting purlines to increase the ability of resistance to wind pressure.Otherwise,use the specially typhoon resistance gasket can resist the damage of the typhoon. In the area of cornice and gable which easily damage by typhoon,the fastener need to add density

The answers:Now it has plenty use in the ecological garden,sewage treatment work,plant of producing acid and alkali substances.The generally FRP sheeting and the steel profiled sheet has big difference in the install and the construction.Need to use reverse type construction and other reinforcement measures.If use the anti-typhoon gasket,it needs to use the intensive nailing fix around the roof.Otherwise,The Ampelite Webglas Gc FRP sheet has a closely safety property to the steel plate.It can construct as the steel sheet way.

The answers:1.The tensile strength of the FRP sheeting can decide the resistance to the wind pressure. In generally,the tensile strength of FRP sheet is about 60MPa,and the space between the purlines is between 1.0 and 1.5m.No matter the thickness of FRP sheeting is 1.2m or 1.5m,the wind resistance pressure can reach to 1KPa.Since the tensile strength of Ampelite 301 FRP sheeting is 68.6MPa,it can satisfy the design demand of wind resistance.

2.To the technical FRP manufacturer and builder,a really good quality FRP sheeting,because of its special use,the major performance index are light transmittance maintain and the UV resistance.The tensile strength above 60MPa is safe.After deeply understand the performance of the FRP sheeting,our Ampelite FRP sheeting has the best function of the maintain of light transmittance and the UV resistance in china.This is the strongly proof of the Ampelite FRP sheeting gurantee 20 years.

The answers:1.All the products of our company is according to the Australian AS/NZS 4257 4:1994 standard.According to the different weight standard,the FRP sheeting separates to the different weight per square meter:1800.2400.3050 and 3660 gram.The corresponding thickness are:1.2mm,1.5mm,2.0mm and 2.5mm.

2.The Australian AS/NZS 4257 4:1994 standard stipulates that the thickness tolerance is allowed ±15%，the allowable weight tolerance per unit is +10%。

3.In the producting of the FRP sheeting,the resin is liquid,subject to gravity,it is thin in the corner of the wave crest.But it is in the allowed tolerance of thickness.This error value has no influence to the products of our company’s products quality.We always have the same quality commitment.

The answers:1.The inflaming FRP sheeting is majorly uses in the special occasions like Steel works,and the place has the blast furnace high temperature,the fire splash or other occasions have special inflaming demand.

2.The inflaming FRP series sheets of our company separate to :F1 level(oxygen index more than30%)and the F2 level(oxygen index more than 26)

3.The inflaming FRP sheeting compare with the generally FRP sheeting.Because in the resin,it has the flame retardant composition,so the aging resistance property is a little weak.In the test,after one year,the FRP sheeting of the F1 level will have the appearance of yellow stain,the F2 level FRP sheeting will have tiny appearance of yellow stain.(The F2 is more easily have yellow stain than the F1),it will more be remarkable as time goes by.

To sum up:The inflaming FRP sheeting is more easily to have yellow stain than the generally FRP sheeting,because in the resin,it has the flame retardant composition.But it does not influence the quality,just the light transmittance reduce as time goes by.Can not guarantee the loss of the light transmittance is 3%-10%.But the yellow stain does not mean the end of the FRP sheeting age,and the chemical character of the FRP sheeting essentially unchanged,also can satisfy the demand of using.So the warranty periodhas no change.

The answers:1.The FRP sheeting is thermoset material,it has better corrosion resistance than the metal material.And the popular type FRP sheeting of Ampelite covers the chemical resistance film,and uses high quality resin.So it has high acid and alkali resistance ability.Usually 10% hydrochloric acid or 10% ammonium hydroxide has slight influence to it.But the 40% hydrochloric has serious influence to it,but can not destroy it.

2.The wonderglass GC FRP sheeting with the technical of GELCOAT,has a high ability of resistant to corrosion.Usually 10% hydrochloric acid or 10% ammonium hydroxide has no influence to it.But the 40% hydrochloric has serious influence to it,but can not destroy it.

The answer:The FRP sheeting can solve the heat preservation problem by doing the double.Its principle is reducing the heat transfer coefficient to reach the demand of heat preservation.Our Ampelite double sheeting heat transfer coefficient can reach 2.5w/(㎡.K).The double sheeting can divide into combined type and the separated type,can satisfy different damands of the roofing.

The answer:In the most of the time,the happen of injuries and deaths are because of the toxic smoke.The flammable FRP sheeting when meeting the open fire,it will quickly burn and form eject smoke belt,can help the toxic smoke going out.So this property can help protect the people from damaging.And the FRP sheeting is heat-set material,it will not have molten drop when burning.

Answers:

1.Except choosing the good quality UV-resistance film and good quality resin,the production curing degree is also quite important.In the test,the production curing degree is all above 95%.The internal molecular structure is appear the approximate uniform mesh.This structure is very stable.The UV,moisture,acid and alkali substances from outside is hardly to influence it.And after the degree of cure improving,its hardness,mechanical strength is also be improved,at the same time,it is quite crisp.

2.The FRP sheeting is a kind of building material,it needs to have certain rigidity and bending strength,it can guarantee the deformation is small when impact by the external force.This property can effective waterproof when the outside force makes the sealant waterproof treatment failed.

3.Some other FRP brands in china for increasing the hardness,it adds the plasticizer.This material does not participate in curing,but can make the FRP sheeting has good tenacity,but has a big influence to the strength.And after using it for period of time,this matter will separate out from the surface,to become a cancerogenic substance.In is forbidden to use in the foreign countries especially in Europe.And after adding the plasticizer,the ageing resistance will reduce a lot.Ampetite state that we never add this material.

4.The FRP sheeting is a auxiliary part of steel structure,is forbidden to tread.Our company state that,the carrying, hositing and the nomal bending in the course will not have any damage to it.

AS a defense:The crisp of FRP sheeting shows the high quality of it.In the normal handle course,if does not appear plenty crack,it has no any influence to the nomal use.Please rest assured that.

Answer：Now in industrial factory building the generally FRP materials are :FRP sheeting,PC,PVC,glass etc,the use of FRP sheeting rate is above 90%.

1、The advantages of FRP sheeting.
