防静电环氧地坪用导电原材料的选择

环氧地坪涂料作为一种日趋惯例的涂料商品,正伴随着其特有的漂亮和功用性广泛运用于工业厂房等基建工程。而其间防静电环氧地坪涂料,更是由于其持久导电的特别功用,越来越广泛适用于电子电器制造厂车间、库房、微机房、电气操控室、印刷厂、纺织厂等需防静电或防爆场所地面涂装。防静电环氧地坪涂料的品种有溶剂型与无溶剂型二种。而其因需兼具装饰作用和特别的防静电功用与其他技能对比也就更难把握,现已日渐成为各家环氧地坪公司的技能中心。而要把握这种技能首先仍是要先把握不一样环氧地坪请求对不一样导电材料的挑选。选对材料是运用获得成功的第一部,也是最为主要的一步。

Epoxy floor coating, as an increasingly routine paint commodity, is widely used in infrastructure projects such as industrial plants with its unique beauty and function. The anti-static epoxy floor coating is more and more widely used in electronics and electrical factory workshop, warehouse, computer room, electrical control room, printing factory, textile factory and other places which need anti-static or explosion protection because of its special function of lasting conduction. There are two kinds of Antistatic Epoxy Floor coatings, solvent type and solvent free type. Because of its need for decoration and special anti-static function, it is more difficult to grasp the comparison with other skills. Now it has become the skill center of various epoxy flooring companies. In order to grasp this skill, we must first grasp the selection of different conductive materials for different floor requests. Selection of materials is the first and most important step in the successful use of materials. 

防静电环氧地坪的分类

Classification of Antistatic Epoxy Floor 

防静电环氧地坪按照系统来分:能够分为一般防静电环氧环氧地坪和防静电环氧自流平地坪两大类。一般一般型防静电环氧地坪面涂厚度约0.1~0.2mm(涂两道),造价比较低,涂装时有溶剂开释,外表平坦度及面层耐磨运用寿命不如自流坪型。从导电性能上讲,由于漆膜较薄也对比简略到达请求。而自流坪型防静电环氧地坪面层厚度在0.7mm以上,涂装时无溶剂开释,施工便捷,外表平坦漂亮,防静电面层耐磨损寿命长,相对技能也较为杂乱,造价略高一点。

Anti-static epoxy flooring can be divided into two categories according to the system: general anti-static epoxy flooring and anti-static epoxy self-leveling flooring. The thickness of general anti-static epoxy floor coating is about 0.1-0.2 mm (two coatings). The cost is relatively low. Solvent is released during coating. The surface flatness and wear-resistant service life of the surface are not as good as that of the self-flow floor coating. In terms of electrical conductivity, the thin film is relatively simple to arrive at. The thickness of self-flowing anti-static epoxy floor is over 0.7 mm, no solvent is released during painting, the construction is convenient, the appearance is flat and beautiful, the anti-static surface wear-resistant life is long, the relative skills are messy, and the cost is slightly higher. 

防静电地坪按照规范来分:因请求不一样细分为耗散型RS106~109Ω和导电型RS<106Ω两种。分别依据运用场合而作不一样的请求。由于有了这些细化的请求和分类所以就必须依据不一样的情况挑选不一样的导电资料作为加工质料,规划最合理的技能和经济配方系统。

Anti-static floors are divided into dissipative RS106-109_and conductive RS < 106_according to the specifications. Different requests are made according to the occasion. Because of these detailed requests and classifications, it is necessary to select different conductive materials as processing materials according to different situations, and to plan the most reasonable skills and economic formulation system. 

防静电材料的分类

Classification of antistatic materials 

常见防静电原材料大概分为以下几种:

The common antistatic materials can be roughly divided into the following categories: 

1.本征类导电粉体:导电性能好,便于加工,但色彩和防腐缺陷显着;

1. eigen conductive powder: good conductivity, easy to process, but the color and anti-corrosion defects are significant. 

2.包覆导电粉:色浅、价低、通用性强;

2. coated conductive powder: light color, low price and versatility. 

3.导静电剂:离子交换,只可短期性导电;

3. conductive agent: ion exchange, which can only conduct short term conduction. 

4.导电纤维:增加量少,导电性能好,不易涣散。

4. conductive fiber: less amount of increase, good electrical conductivity, not easy to lax. 

溶剂型防静电环氧地坪材料挑选

Selection of solvent based anti-static epoxy floor materials 

一般防静电环氧地坪可选用复合导电云母粉BC-C来制备。现在溶剂型的,技能已十分老练,电阻指数可到达105~109Ω。能够到达各种防静电请求,能够规划增加量来到达各种请求。

The general anti-static epoxy floor can be prepared by using composite conductive mica powder BC-C. Now the solvent based technology is very sophisticated, and the resistance index can reach 105~109 ohms. Able to get all kinds of anti-static requests, we can plan to increase the amount to arrive at various requests. 

固含量增加剂24%-28%,规划导电值Ω分别对应为109-106由于导电纤维针对较薄的漆膜因不易涣散也简略呈现外表的露头情况,显着的影响外表的装饰性(其长度约束也会影响喷涂施工);而金属和碳黑粉料又因色彩约束和电腐蚀(导电衰竭)等要素无法运用,因而现在看来兼顾漂亮功能和操作性的复合导电云母粉是最为适宜一般防静电地坪资料。其具有最为适宜的导电性和外观情况而深受现在地坪厂商的认可。如导电粉更是现已运用于现在国内的绝大多数一般防静电环氧地坪材料,具有遍及的技能支持和客户认可。

The planned conductivity value_corresponds to 109-106 with solid content increasing agent 24%-28%, respectively, because conductive fibers are not easy to disperse and show a brief appearance outcrop for thinner paint film, which has a significant impact on the decorative appearance (its length constraint will also affect the spraying construction); while metal and carbon black powder are also affected by color constraint and electrical corrosion (conductivity). Electric exhaustion) and other factors can not be used, so now it seems that the composite conductive mica powder with beautiful function and operability is the most suitable material for general anti-static floor. It has the most suitable conductivity and appearance and is well recognized by the current floor manufacturers. For example, conductive powder is now used in most of the general anti-static epoxy flooring materials in China, with extensive technical support and customer acceptance. 

题外话:现在市面上也有如导电钛白、导电砂等包覆型导电材料。可是由于其颗粒形状不似云母简略搭接,而导电功能不易到达最好,加之报价本钱较高无法到达广泛运用。

Digression: there are also conductive conductive materials such as conductive titanium dioxide and conductive sand on the market. However, due to its particle shape is not like mica simple lap, and the conductive function is not easy to reach the best, coupled with the high cost of quotation can not be widely used. 

无溶剂防静电地坪材料挑选

Selection of solvent-free anti-static floor material 

长期以来,对于自流坪防静电地坪挑选的导电资料一向存在着必定的难点。主要要素为:由于涂层厚度的增加,漆膜在固化时树脂上浮的倾向会增大(对比于溶剂型),再加上导电资料的下沉要素。致使导电资料在无溶剂漆膜中的纵向散布不是接连均匀的,上层导电材料的质量百分比显着低于平均值。恰是由于它的这一特色,使得无溶剂防静电自流平的出产与施工要远远难与溶剂型。

For a long time, there has always been some difficulty in selecting conductive materials for self leveling anti-static floor. The main factors are as follows: with the increase of coating thickness, the tendency of resin floating will increase (compared with solvent type) when the paint film is cured, and the sinking factor of conductive data will be added. As a result, the longitudinal dispersion of conductive materials in solvent-free paint film is not continuous uniform, and the mass percentage of conductive materials in the upper layer is significantly lower than the average value. It is precisely because of its characteristics that the production and construction of solvent-free anti-static self-leveling is far from being solvent-based. 

之前现已讨论过石墨粉和金属粉的商品特征约束了其在地坪面漆中的运用,且抗静电剂又由于短期有用而不具备持久的有用性,所以不契合地坪的运用请求,因而下面着重讨论一下复合导电云母粉和导电纤维在无溶剂中的运用。

The commercial characteristics of graphite powder and metal powder have been discussed before, which restrict their application in floor paint. Moreover, the antistatic agent does not meet the application requirements of floor paint because of its short-term usefulness and long-term usefulness. Therefore, the following discussion focuses on the application of composite conductive mica powder and conductive fibers in solvent-free environment. 

由于要到达相同作用,在无溶剂中复合导电云母粉的增加量要远远大于溶剂型的,过多的增加导电粉会使系统的全体粘度增加、流平性降低、漆膜硬度降低一级。且会增加施工难度(施工厚度操控欠好会使上层的导电资料质量百分比发生动摇,然后导电值不安稳),本钱也相对较高。这些要素使得复合导电云母粉在无溶剂中的运用受到约束。

To achieve the same effect, the increase of composite conductive mica powder in solvent-free medium is much larger than that in solvent-based medium. Excessive increase of conductive powder will increase the whole viscosity of the system, reduce the leveling property and reduce the film hardness by one order. And it will increase the difficulty of construction (poor thickness control will shake the percentage of conductive data quality in the upper layer, and then the conductive value is unstable), and the cost is relatively high. These factors restrict the use of composite conductive mica powder in solvent free applications. 

导电纤维因涣散技能的处理,现在得到了较广泛的运用。它的长处是:运用便利、色泽亮堂、本钱低、导电功能好等。但它也有限制的当地:独自用导电纤维制备防静电自流平,外表电阻只可安稳的操控在10的次方~10的六次方Ω。但要做安稳的106~109Ω好不简单,且对施工厚度请求高(底漆电阻、厚度)。纤维长度也受到约束,纤维过长则影响表观,太短则影响导电性能在防静电自流坪中混合运用导电粉和导电纤维可有用的处理上述二限制性。它的原理是用导电粉来操控触摸电阻,而用导电纤维来处理导电资料纵向散布不均匀的疑问。

Conductive fibers have been widely used because of their lax skills. Its advantages are: convenience, bright colors, low cost, good electrical conductivity, etc. But it also has limitations: the self-leveling of anti-static electricity can be made by conductive fibers alone, and the external resistance can only be controlled steadily from the order of 10 to the sixth order of 10_. But it is not easy to make 106-109_stable, and the construction thickness is required high (primer resistance, thickness). Fiber length is also constrained, too long fibers will affect the appearance, too short fibers will affect the conductivity in the anti-static self-current plateau mixed with conductive powder and conductive fibers can be used to deal with the above two limitations. Its principle is to use conductive powder to control the touch resistance, and conductive fibers to deal with the problem of non-uniform longitudinal distribution of conductive data. 

导电粉与导电纤维的混合体,运用合理的比例,经过特别的办法制备而成。它有以下特色:

The mixture of conductive powder and conductive fiber is prepared by special methods in a reasonable proportion. It has the following characteristics: 

⒈可经过导电底漆来操控外表电阻

The surface resistance can be controlled by conductive primer. 

底漆导电值Ω:10的4次方 ,<10的4次方

Primers with a conductivity value of 10: 4 times, 10 times 4 times. 

规划导电值Ω:106-9,104 -5 ,<104

Planning electrical conductivity value: 106-9104 -5, < 104 

⒉ 出产操作简略,对施工请求低,电阻安稳性高等显着长处。彻底处理之前的独自运用导电纤维或是到导电粉体发生的地坪装饰性、施工性、功用性无法到达统一的疑问。

The production operation is simple and has obvious advantages for low construction request and high resistance stability. Completely deal with the problem that the decorative, constructive and functional properties of the floor, which happened before the sole use of conductive fibers or conductive powders, can not reach a unified level. 

⒊ 导电功能安稳。有用处理单纯运用导电纤维简略发生的静电盲点疑问,一起处理运用导电粉简略沉降和吸油量大等疑问。施工厚度适应性大,能够一次成膜2MM.

Conductive function is stable. It is useful to deal with the problems of electrostatic blind spot occurring simply by using conductive fibers, and to deal with the problems of simple sedimentation and large oil absorption by using conductive powders together. The thickness of construction is large enough to be 2MM. once. 

本来此类办法在国外现已具有必定的运用技能根底,国外公司通常经过增加多种契合材料的方法来完结漆膜的安稳电阻值。可是由于选用不一样比例的导电资料请求漆膜必定要对比厚,一起还必须和专用的固化剂相配合以到达适宜的固化时刻,并且由于填料过多本钱和调色都有疑问而无法到达推广。而BC-W11由于增加量适中,并且材料比重适宜恰巧着力改善了这些方面,拓荒了新的导电材料思路,成为安稳、牢靠、便利的自流平用导电材料。

This kind of method already has certain application skills in foreign countries. Foreign companies usually finish the stable resistance value of the paint film by adding a variety of matching materials. However, due to the selection of different proportions of conductive materials, the paint film must be thicker, together with a special curing agent to achieve the appropriate curing time, and due to the excessive cost of fillers and color mixing are doubtful, can not reach the promotion. BC-W11 is a stable, reliable and convenient self-leveling conductive material because of its moderate increase and appropriate material proportion. 

本来防静电地坪作为功用型材料,对比较导电PVC、导电地毯等有具有全体性强,本钱低一级优势。而安稳导电性恰是这个商品的中心、各个出产厂家竞赛的中心。所以第一步挑选适宜的资料变的至关主要。现已得到很多实践证明的复合导电粉BC-C和全新概念的BC-W11能够应对现在导电地坪的各种请求,这无疑将大大推动导电环氧地坪行业的前进和开展。

The original anti-static floor as a functional material, compared with conductive PVC, conductive carpet, etc., has a strong integrity, low cost advantage. And stable electrical conductivity is the center of this commodity and the center of every manufacturer's competition. So the first step is to choose the right information. It has been proved by many practices that the composite conductive powder BC-C and the new concept BC-W11 can meet various requirements of conductive floor, which will undoubtedly greatly promote the progress and development of conductive epoxy floor industry.
