防靜電环氧地坪用導電原材料的選擇

环氧地坪塗料作為一種日趨慣例的塗料商品，正伴隨著其特有的漂亮和功用性廣泛運用於工業廠房等基建工程。而其間防靜電环氧地坪塗料，更是由於其持久導電的特別功用，越來越廣泛適用於電子電器制造廠車間、庫房、微機房、電氣操控室、印刷廠、紡織廠等需防靜電或防爆場所地面塗裝。防靜電环氧地坪塗料的品種有溶劑型與無溶劑型二種。而其因需兼具裝飾作用和特別的防靜電功用與其他技能對比也就更難把握，現已日漸成為各傢环氧地坪公司的技能中心。而要把握這種技能首先仍是要先把握不一樣环氧地坪請求對不一樣導電材料的挑選。選對材料是運用獲得成功的第一部，也是最為主要的一步。
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.
防靜電环氧地坪的分類
Classification of Antistatic Epoxy Floor
防靜電环氧地坪按照系統來分：能夠分為一般防靜電环氧环氧地坪和防靜電环氧自流平地坪兩大類。一般一般型防靜電环氧地坪面塗厚度約0.1～0.2mm（塗兩道），造價比較低，塗裝時有溶劑開釋，外表平坦度及面層耐磨運用壽命不如自流坪型。從導電性能上講，由於漆膜較薄也對比簡略到達請求。而自流坪型防靜電环氧地坪面層厚度在0.7mm以上，塗裝時無溶劑開釋，施工便捷，外表平坦漂亮，防靜電面層耐磨損壽命長，相對技能也較為雜亂，造價略高一點。
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.
防靜電地坪按照規范來分：因請求不一樣細分為耗散型RS106～109Ω和導電型RS<106Ω兩種。分別依據運用場合而作不一樣的請求。由於有瞭這些細化的請求和分類所以就必須依據不一樣的情況挑選不一樣的導電資料作為加工質料，規劃最合理的技能和經濟配方系統。
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.
防靜電材料的分類
Classification of antistatic materials
常見防靜電原材料大概分為以下幾種：
The common antistatic materials can be roughly divided into the following categories:
1.本征類導電粉體：導電性能好，便於加工，但色彩和防腐缺陷顯著；
1. eigen conductive powder: good conductivity, easy to process, but the color and anti-corrosion defects are significant.
2.包覆導電粉：色淺、價低、通用性強；
2. coated conductive powder: light color, low price and versatility.
3.導靜電劑：離子交換，隻可短期性導電；
3. conductive agent: ion exchange, which can only conduct short term conduction.
4.導電纖維：增加量少，導電性能好，不易渙散。
4. conductive fiber: less amount of increase, good electrical conductivity, not easy to lax.
溶劑型防靜電环氧地坪材料挑選
Selection of solvent based anti-static epoxy floor materials
一般防靜電环氧地坪可選用復合導電雲母粉BC-C來制備。現在溶劑型的，技能已十分老練，電阻指數可到達105～109Ω。能夠到達各種防靜電請求，能夠規劃增加量來到達各種請求。
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 resistanc环氧地坪e 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.
固含量增加劑24%-28%,規劃導電值Ω分別對應為109-106由於導電纖維針對較薄的漆膜因不易渙散也簡略呈現外表的露頭情況，顯著的影響外表的裝飾性（其長度約束也會影響噴塗施工）；而金屬和碳黑粉料又因色彩約束和電腐蝕（導電衰竭）等要素無法運用，因而現在看來兼顧漂亮功能和操作性的復合導電雲母粉是最為適宜一般防靜電地坪資料。其具有最為適宜的導電性和外觀情況而深受現在地坪廠商的認可。如導電粉更是現已運用於現在國內的絕大多數一般防靜電环氧地坪材料，具有遍及的技能支持和客戶認可。
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.
題外話：現在市面上也有如導電鈦白、導電砂等包覆型導電材料。可是由於其顆粒形狀不似雲母簡略搭接，而導電功能不易到達最好，加之報價本錢較高無法到達廣泛運用。
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.
無溶劑防靜電地坪材料挑選
Selection of solvent-free anti-static floor material
長期以來，對於自流坪防靜電地坪挑選的導電資料一向存在著必定的難點。主要要素為：由於塗層厚度的增加，漆膜在固化時樹脂上浮的傾向會增大（對比於溶劑型），再加上導電資料的下沉要素。致使導電資料在無溶劑漆膜中的縱向散佈不是接連均勻的，上層導電材料的質量百分比顯著低於平均值。恰是由於它的這一特色，使得無溶劑防靜電自流平的出產與施工要遠遠難與溶劑型。
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.
之前現已討論過石墨粉和金屬粉的商品特征約束瞭其在地坪面漆中的運用，且抗靜電劑又由於短期有用而不具備持久的有用性，所以不契合地坪的運用請求，因而下面著重討論一下復合導電雲母粉和導電纖維在無溶劑中的運用。
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.
由於要到達相同作用，在無溶劑中復合導電雲母粉的增加量要遠遠大於溶劑型的，過多的增加導電粉會使系統的全體粘度增加、流平性降低、漆膜硬度降低一級。且會增加施工難度（施工厚度操控欠好會使上層的導電資料質量百分比發生動搖，然後導電值不安穩），本錢也相對較高。這些要素使得復合導電雲母粉在無溶劑中的運用受到約束。
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.
導電纖維因渙散技能的處理，現在得到瞭較廣泛的運用。它的長處是：運用便利、色澤亮堂、本錢低、導電功能好等。但它也有限制的當地：獨自用導電纖維制備防靜電自流平，外表電阻隻可安穩的操控在10的次方～10的六次方Ω。但要做安穩的106～109Ω好不簡單，且對施工厚度請求高（底漆電阻、厚度）。纖維長度也受到約束，纖維過長則影響表觀，太短則影響導電性能在防靜電自流坪中混合運用導電粉和導電纖維可有用的處理上述二限制性。它的原理是用導電粉來操控觸摸電阻，而用導電纖維來處理導電資料縱向散佈不均勻的疑問。
Conductive fibers have been widely used because of their lax skill彩色沥清地坪s. 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.
導電粉與導電纖維的混合體，運用合理的比例，經過特別的辦法制備而成。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可經過導電底漆來操控外表電阻
The surface resistance can be controlled by conductive primer.
底漆導電值Ω：10的4次方 ，＜10的4次方
Primers with a conductivity value of 10: 4 times, 10 times 4 times.
規劃導電值Ω：106-9，104 -5 ，＜104
Planning electrical conductivity value: 106-9104 -5, < 104
⒉ 出產操作簡略，對施工請求低，電阻安穩性高等顯著長處。徹底處理之前的獨自運用導電纖維或是到導電粉體發生的地坪裝飾性、施工性、功用性無法到達統一的疑問。
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 導電功能安穩。有用處理單純運用導電纖維簡略發生的靜電盲點疑問，一起處理運用導電粉簡略沉降和吸油量大等疑問。施工厚度適應性大，能夠一次成膜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.
本來此類辦法在國外現已具有必定的運用技能根底，國外公司通常經過增加多種契合材料的方法來完結漆膜的安穩電阻值。可是由於選用不一樣比例的導電資料請求漆膜必定要對比厚，一起還必須和專用的固化劑相配合以到達適宜的固化時刻，並且由於填料過多本錢和調色都有疑問而無法到達推廣。而BC-W11由於增加量適中，並且材料比重適宜恰巧著力改善瞭這些方面，拓荒瞭新的導電材料思路，成為安穩、牢靠、便利的自流平用導電材料。
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.
本來防靜電地坪作為功用型材料，對比較導電PVC、導電地毯等有具有全體性強，本錢低一級優勢。而安穩導電性恰是這個商品的中心、各個出產廠傢競賽的中心。所以第一步挑選適宜的資料變的至關主要。現已得到很多實踐證明的復合導電粉BC-C和全新概念的BC-W11能夠應對現在導電地坪的各種請求，這無疑將大大推動導電环氧地坪行業的前進和開展。
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.
