Jinan rockery manufacturing knowledge: what are the advantages and disadvantages of different rockery manufacturing
At present, there are almost two kinds of rockery manufacturing processes on the market: FRP process and GRC process. Both of them have their own advantages and disadvantages. However, they are often used in the manufacture of plastic rockery rockery. Therefore, people should be seated in the number when choosing the craft.
What are the manufacturing processes of rockery? What are the differences and advantages and disadvantages?
I. Different information
1. FRP process: It is the abbreviation of glass fiber reinforced resin. It is a light weight and tough composite material composed of unsaturated polyvinyl acetate resin and glass fiber, commonly known as FRP.
2. GRC process: It is the abbreviation of glass fiber reinforced cement. It is a high-strength composite which hardens alkali-resistant glass fiber into low-alkali cement mortar.
2. The advantages and disadvantages of rockery manufacturing process (FRP process and GRC process):
The advantages of FRP process are: fast shaping speed, thin and light weight, good rigidity, durability, low cost, convenient transportation, and indirect construction in the site.
GRC工艺的优点： 假山制造的造型、效纹逼真；资料本身质量轻，强度高，抗老化且耐水湿，易停止工厂化消费，施工办法简便、快捷、造价低，可普遍运用；GRC假山造型设计、施工工艺较好，可塑性大，在造型上需求特殊表现时可满足要求，加工成各种复杂型体，与动物、水景等配合，可使景观更富于变化和表现力； GRC造假山可应用计算机停止辅佐设计，完毕过来假山工程无法做到石块定位设计的历史，使假山不只在制造技术，而且在设计手腕上获得了新打破。具有环保特点，可取代真石材，增加对自然矿产及林木的开采。
The advantages of GRC technology are: the shape and effect of rockery manufacturing are realistic; the data itself is light in quality, high in strength, anti-aging and water-wet resistance, easy to stop industrial consumption, simple, fast in construction method, low in cost, and can be widely used; GRC rockery modelling design, construction technology is good, plasticity is large, special performance in modelling needs can meet the requirements, processing into a variety of complex types, With the cooperation of animals and waterscapes, the landscape can be more changeable and expressive; GRC artificial hill can be used to stop assistant design by computer, and after the completion of the rockery project, it can not achieve the history of stone positioning design, which makes the artificial hill not only in the manufacturing technology, but also in the design wrist to achieve a new breakthrough. It has the characteristics of environmental protection. It can replace real stone and increase the exploitation of natural minerals and forests.
Defects of FRP process: the ratio of resin liquid to glass fiber is not easy to control, and the requirement for the manufacturer of rockery is high; the rest condition is poor, the resin solvent is inflammable; the toxicity and odor in the process of rockery manufacturing; the glass fiber reinforced plastic is vulnerable to exterior crispness under strong outdoor sunshine, and its life is 20-30 years.
GRC工艺的缺陷：量重，假山高层作业搬运难，不平安 ;平均性差，有气孔，形变大 ;假山制造工期较慢，若改装，构件将根本作废 ;GRC工艺的假山需求很专业工人，施工人员多。
Defects of GRC technology: heavy, difficult to handle and uneasy in high-level operation of rockery; poor average, with air holes, large deformation; slower construction period of rockery, if refitted, components will be fundamentally scrapped; rockery of GRC technology needs very professional workers and many constructors.
