树脂混凝土的特性
具有混凝土的成型性,可铸造成各种复杂的形状,且尺寸精确;更高的强度/重量比,具高抗压及高抗弯能力;完全不含水泥及水,无水化作用,而无毛细现象,不吸水,纵使有侵蚀现象,也仅在表面发生,不会影响结构完整性.结构特性稳定,无化学残余,有如玻璃般的环境稳定性,对环境不会造成任何污染.黏结容易,止水性高,在工地现场加工(如钻孔、切割等),不造成质量与功能的损失.
优点:
抗压及抗弯强度大
树脂立体网状分子结构,与填料反应时能产生强大的键结能力,故其具有极高抗压和抗弯强度,抗压强度经特别设计可高达2500kg/cm2
耐酸碱
抗酸碱度高达PH1---10.聚酯树脂混凝土抗腐蚀性强,对于生物硫酸侵蚀及酸性土壤的抵抗能力特佳.
抗腐蚀
无毛细孔、不吸水,所有的侵蚀、破坏皆阻绝在外,可防止生物在其表面滋长、破坏;不让有害生物有任何生存机会.短时间超高浓度的化学腐蚀,因高量骨材填充,且无毛细现象,破坏仅会在表面发生,不会深入混凝土内部,破坏结构强度.
环境稳定性
聚酯树脂混凝土胶结后比热塑性树脂材料之稳定性更高.有如玻璃般的稳定性.强度高、环境稳定性佳,于国内属于绿色环保第二类材料;在欧盟,允许回收轧制成碎石再度利用,甚至直接做为路基材料,而无环境污染的困扰.
耐候性佳
具有良好的耐候性,即使在极恶劣的环境下仍然不会有脆裂或破坏的现象产生.因分子结构稳定,具有良好的抗紫外线能力,不似一般工程塑料会因为紫外线造成材料老化、脆裂现象.耐冻融,不怕寒害,可安心的使用在高山下雪地区.
寿命长
在正确的规格要求及安装下,几乎有无限制的设计使用年限,因此强烈的建议,应搭配最好的接头止水材料.相对于水泥混凝土、塑料及其它材料,使用年限高,每年摊提成本相对较低,故采用树脂混凝土材料之经济效益远高于其它材料.
重量轻、尺寸精确
强度/重量比极高.相同规范强度之制品,可以减少材料厚度,能大幅降低成品重量,使制品轻量化.并且降低运输、吊装、开挖等成本.可塑性强,能依各种不同规格尺寸制作各种精确的形状.
易于加工、安装、黏着
经实验证明,抗弯试验折断后,黏结再做抗弯,不会由原断裂处断裂;利于连接、接着,更提升整体的水密性.具有施工容易、安装方便等优点,对于工期的掌控有极大的帮助.加工容易,可以进行钻、切、等加工.
表面光滑、免维护保养
表面光滑致密,粗糙系数n=0.010,水力特性佳,不易堆积沈淀物,可减少维护的次数.可不定期的以高压水柱冲洗,对于沉淀物淤积的清除较为容易,而不似水泥混凝土般,有损坏的危险,节省维护费用的支出.
抗冻融
交替的冻融会降低水泥的性能,而对树脂混凝土的影响很小,因树脂混凝土内部没有吸放水的孔结构,进行了1600次冻融的测试没有发生质量性能的变化.
抗渗透和吸水率
树脂混凝土的吸水率在按重量的1%以下.比木材和水泥要小的多,渗透率为0.因水泥混凝土中总有部分水没有参与反应,而留下大小不同的毛细孔隙,而树脂在反应中最终全部参与固化反应,不产生相连的内部孔结构,而内部孔结构是因为混合时进入的空气.
树脂混凝土U形排水槽的应用范围
这种产品在国外应用非常广泛.主要是应用于市政建设,例如:街道排水,广场排水,高速公路,机场,码头,公园,庭院,体育场等,在欧洲一般只要有人活动的公共场所都有这些产品.
树脂混凝土的成份如下 :
填料:石英砂,碳酸钙
树脂:不饱和聚脂树脂
固化剂:过氧化甲乙酮(MEKP) .
促进剂:异辛酸钴苯乙稀溶液.

Characteristics of resin concrete
With concrete forming,and can be cast into complex shapes,and sizes accurate; higher strength / weight ratio,high resistance and high flexural capacity; completely free of cement and water,water effect,and no capillarity,non-absorbent,even though erosion has also only happen on the surface will not affect the structural integrity.Structural characteristics of stability,free of chemical residues,like the glass-like environment of stability,on the environment will not cause any pollution.Binder easy sealing of the highest in the processing site (such as drilling,cutting,etc.),not to cause loss of quality and function.
Advantages:
Compressive and flexural strength
Resin molecular structure of three-dimensional mesh,with the filler reaction time can produce a strong bonding capacity,so its very high compressive and flexural strength,compressive strength can be as high as specially designed 2500kg/cm2
Acid
PH as high as anti-PH1 --- 10.Polyester resin concrete corrosion resistance,and for bio-erosion and acid sulfate soil resistance excellent.
Corrosion-resistant
Without pores,non-absorbent,all the erosion,damage to both block out to prevent biological growth on the surface,destruction; to prevent harmful organisms have any chance of survival.Short ultra-high concentrations of chemical corrosion,due to the high volume of aggregate fill,and no capillarity,destruction will only happen on the surface,not depth of concrete internal and undermine structural strength.
Environmental Stability
After the polyester resin cement concrete than the thermoplastic resin material of a higher stability.Like a glass-like stability.High strength,good environmental stability in the domestic green environmental protection belong to the second category of materials; in the European Union,permit recovery of re-rolling into the use of gravel,or even directly as roadbed material,and no environmental pollution problems.
Weather resistance good
Has a good Weather resistance,even in extremely adverse circumstances still has not rattle or damage arising from the phenomenon.Due to the molecular structure of stability,with good anti-UV ability,unlike the general engineering plastics because of ultraviolet radiation caused by material aging,brittle fracture phenomenon.Freeze-thaw resistant,do not fear chilling injury,the use of safe areas in the Alpine snow.
Long life
In the correct specification and installation,the almost unlimited design life,it strongly suggested that the best joints with sealing material.Compared with the cement concrete,plastic and other materials,the use of life high,the annual amortization cost is relatively low,so the use of resin concrete material is much higher than the economic benefits of other materials.
Light weight,size precision
Strength / weight ratio extremely high.Standardize the intensity of the same products,can reduce the material thickness,can substantially reduce the weight of finished product,so that lightweight products.And lower transport,lifting,digging and other costs.Plasticity,and can be a variety of different specifications according to the size of the shape of the production of precision.
Easy processing,installation,mount
The experiment proved that the bending fracture tests,the bond bending again,not by the original fracture鏂?澶凔 conducive to connect,and then,but also enhance the overall water tightness.With the construction of easy,convenient installation,etc.,for the control period of great help.Easily processed,can be drilled,cut,and other processing.
Surface smooth,maintenance-free maintenance
Dense smooth surface,roughness coefficient n = 0.010,hydraulic characteristics of good and difficult to accumulation of sediments can reduce the frequency of maintenance.May from time to time by high-pressure water rinse for removal of sediment deposition relatively easy,and not seem like concrete,has the risk of damage,save maintenance costs.
Freeze-thaw resistance
Alternate freezing and thawing will reduce the performance of cement,while the impact of resin concrete is very small,because it lacked concrete resin water absorption of the pore structure,carried out 1600 times freeze-thaw test the quality of performance did not happen changes.
Anti-permeability and water absorption
Resin concrete water absorption by weight in less than 1%.Than wood and cement,to many small and permeability to 0.Cement concrete due to have part of the total water not involved in the response,while leaving the pores of different sizes backlash,and resin in the reaction of all involved in the final curing reaction,does not produce linked to the internal pore structure,and internal pore structure are mixed because when entering the air.
Resin concrete U-shaped drainage channels on the scope of application
This product is widely used abroad.Mainly applies to the municipal building,such as:street drainage,square drainage,highways,airports,wharves,parks,gardens,stadiums,etc.,in Europe as long as it was the activities of the general public places have these products.
Resin concrete composition is as follows:
Filler:quartz sand,calcium carbonate
Resin:unsaturated polyester resins
Curing agent:methyl ethyl ketone peroxide (MEKP).
Enhancers:bitter differences dilute solution of cobalt acetophenone.
