科技创新让谷壳变废为宝

　　节能减排“EPF”墙板一枝独秀

　　Technology which produces EPF from natural waste materials        

　　——衢州海荣公司新型墙材生产技术前景广阔

　　浙江衢州市海荣新型墙体材料有限责任公司，是一家集科研、开发、制造、售后服务于一体的中外合作技术型企业。公司拥有自主知识产权，已获得国家多项专利，产品归入国家产业结构调整鼓励类和《浙江省外商投资优先发展产业目录》。

　　衢州海荣公司目前推出两个大类产品：一是德垒牌“EPF”轻质环保墙板系列；二是制作轻质环保墙板的节能生产线设备。其中，“EPF”墙板系列，以谷壳、秸杆等农业剩余物和碳酸氢钙为主要原料，配以阻燃剂、改性剂，经塑性挤压工艺生产而成。产品性能指标已通过国家一系列检测和意大利国际检测，完全符合国家JC/T169－2005建筑工业行业标准。产品不仅可以替代实心粘土砖，扭转烧砖毁地局面，遏制CO2的排放，保护环境和耕地，而且具有自重轻（约为双面抹灰墙的1/3）、墙体薄（厚9~12㎝）、防火与保温（为A级保温不燃品）、施工便捷（采用板块式拼装、干式作业）、投资省（利用其作为建筑围护内外墙，可节省建筑投资10%~15%）等特点，在“轻质、节能、利废、环保”等方面均优于实心粘土砖。在以稻谷为主要农作物和气候炎热的国家及地区，有非常广阔的利好市场前景。推广和使用“EPF”墙体材料，必将有效推进建材工业向资源节约型、环境友好型发展的步伐。海荣公司研制的“EPF”墙板生产线设备，包括送料捏合、挤压成型、输送养护等系统。整体技术指标居国内先进水平。与目前国内外同类型生产设备相比，具有主机节能、操作人少、输送合理等优点。公司独创的条板成型机，每分钟可挤压成型厚度0.09m至0.12m，宽度0.6m、长度3m左右的墙板2~3㎡。一条生产线年产量在50万㎡以上。

　　衢州海荣公司的“EPF”轻质墙板在小范围试用已有3年。尽管目前该产品仍处在试产和改进完善中，但已引起国内外不少有识之士和客商的极大兴趣和重视，期望与衢州海荣公司合作，在其国家或地区布设生产线，建厂和推广使用“EPF”墙板材料。泰国、伊朗、埃及、尼日利亚、意大利等国家和中国的香港、广东、新疆等地，纷纷组织商务考察团，前来衢州海荣公司考察、洽谈合作业务。

　　节能减排，与时俱进。革新墙材，利国利民。衢州海荣公司热烈欢迎海内外客商加盟生产“EPF”墙板系列材料，共谋发展，共创辉煌。

　　Technology Innovation, Energy Conservation and Emission Reduction Make EPF Wall Material Outstanding

　　

　　

　　Zhejiang Quzhou Hairong New Type Wall Construction Materials Co., Ltd. is located in Quzhou City, Zhejiang Province. It is a technology-based comprehensive Chinese-Foreign Contractual Joint Venture involved in R&D, manufacturing and after-sale services. It possesses proprietary intellectual property rights, and has won many national patents. The products of the company are categorized in the directories of the Government- supported Re-structuring Enterprises, and are listed in the Catalogue for the Recommended Businesses for Foreign Investment of Zhejiang Province.

　　Quzhou Hairong Corporation launches two major categories of products. One is "EPF" environmentally friendly light wallboard series，and the other is the energy-saving production line used for manufacturing light environmentally-protective wallboard.

　　The EPF wall panel series consist mainly of agricultural residues like chaff and straw, and calcium bicarbonate as raw materials, which are mixed with flame retardant and modifier. The panels are formed by plastic extrusion.

　　The products have passed a series of tests both domestic and abroad, and measure up to the industrial standard of National JC/T169-2005 Architectural Industrial Standard.

　　The products can substitute solid clay bricks, avoid damage to the earth, curb the emission of CO2, and protect the environment and farmland. Other special characteristics include being light weight (about 1/3 of a double side plastering wall), having a thickness of 9 to 12 cm, having fire resistance and thermal insulation (A-level non-combustible insulation material), being convenient for construction (plate-type assembling and dry construction), and being cost effective (An enclosure wall of this material can reduce construction costs by 15% to 20%). It has advantages over solid clay bricks in terms of weight, energy-saving capacity, recycling and environmental protection.

　　There are wide market prospects in areas where rice is the main agricultural produce and in regions with hot climatic conditions.

　　Promoting the use of EPF materials will propel the construction material industry towards resource-conservation and environmental protection.

　　The production line of EPF wall material produced by Hairong contains a sent material kneading system, an extrusion moulding system, and a conservation and delivery system.

　　The technological parameters are superior to others nationally. Compared with similar current production equipment, Hairong’s equipment is more energy-saving, requires fewer operators, and has a more appropriate transportation system. The lath panel molding machine, invented by the company, has an output of 2 to 3 square meters per minute, with each panel being a thickness of 0.09 to 0.12m, a width of 0.6m and a length of 3m. The annual output of a production line is more than 500,000 m2.

　　It has been 3 years since EPF lightweight wall panels by Hairong Co., Ltd were first tried on a small scale. Although the product is still in trial production and is being continually improved, it has attracted great interest from people and businesses at home and abroad. They are looking forward to cooperating with us and setting up factories in their home countries and promoting the use of "EPF" wall materials. Business delegations from countries including Thailand, Iran, Egypt, Nigeria, Italy and districts such as Hong Kong, Guangdong and Xinjiang Province are coming to assess or discuss cooperation with us.

　　Energy saving and emission reduction demonstrate the company’s desire to keep up with the times. This Innovation in wall materials is beneficial for both the country and its people. Hairong Co., Ltd. warmly welcomes both domestic and foreign businesses to collaborate in the production of EPF wall materials, and together to develop and achieve prosperity.
