粉末噴涂技術盡管有很多優勢,并在環保方面遠遠超越噴漆技術,但因為進入國內時刻較短在國內的普及程度還不是很高,很多用戶對噴涂技術的了解還不是很深。因而筆者熱心提示廣大用戶在挑選靜電粉末噴涂設備時需要參閱對比專業的主張。咱們先來看看幾個對比典型的對濟南氟碳噴涂使用的噴槍功能的認識誤區:
Powder spraying technology although there are a lot of advantages in environmental protection, and far beyond the paint technology, but because of the short time to enter the domestic penetration in the country is not very high, many users understand of spraying technology is not deep. Therefore, I am eager to remind the majority of users in the selection of electrostatic powder spraying equipment need to refer to the views of professional. Let us take a look at some of the typical understanding of the role of the spray gun used in Ji'nan fluorocarbon coating:
濟南氟碳噴涂誤區一:噴槍電壓越高,上粉越快越好。
Ji'nan fluorocarbon spray misunderstanding: the higher the spray gun voltage, the faster the better powder.

.
1.依據靜電噴涂的根本物理原理咱們可以知道,當充電電壓超越一定數值時反而會激化“法拉第效應”和“反電離效應”的發作,愈加影響上粉率。
1 based on the fundamental principle of electrostatic spraying, we can know that when the charging voltage exceeds a certain value, it will intensify the "Faraday effect" and "anti ionization effect" of the attack, the more affected the powder rate.
2.靜電電壓過高容易形成槍尖打火的景象,容易在工件表面留下針孔,形成表觀質量不良。
2 high voltage electrostatic ignition gun tip is easy to form the scene, easy to leave the pinhole on the workpiece surface, the formation of apparent quality.
3.高壓打火的景象也會添加噴粉室內粉塵焚燒的景象。
3 high-voltage scene will also add the powder dust indoor scene burning.
因而,在實踐運用過程中應當依據粉末的特色,工件的特色等調理電壓至恰當的期間才干取得對比杰出的噴涂作用。
Therefore, in the course of the application of the process should be based on the characteristics of the powder, the characteristics of the workpiece to adjust the voltage to the appropriate period of time to achieve a good comparison of the role of spraying.
濟南氟碳噴涂誤區二:形狀簡略的工件可以運用功能差些的噴槍。
Ji'nan fluorocarbon spray error two: the shape of the workpiece can be simple to use the function of the spray gun.
疑問剖析:
Question analysis:
1.有些用戶以為工件的形狀簡略,所以不需要功能極好的噴槍。事實上功能好的噴槍絕不僅僅是對形狀的客服能力強,更主要的是出粉狀況的均勻程度會完成更好的表觀涂層和上粉率。而且上粉率高了當然會節約粉末,大幅度下降出產本錢。
1 some users believe that the shape of the workpiece is simple, so it does not require a very good function of the spray gun. In fact, a good function of the spray gun is not only the shape of the customer service ability is strong, the more important is the uniformity of powder situation will be completed better coating and powder coating rate. And on the powder rate of course will save powder, a substantial decline in production costs.
2.靜電功能好也會加速出產速度,進步作業效率。
2 electrostatic function will accelerate the production speed, improve operating efficiency.
3.上粉均勻也會進步成品率,下降廢品率,使出產管理愈加輕松。
3 powder will also improve the finished product rate, decreased waste rate, so that production management easier.
4.功能欠好的噴槍因為運用的元器件功能對比差,盡管本錢稍低,然而故障率會高的多,即便廠家及時修理也難免耽誤出產。
4 function is not good spray gun because of the use of the function of the components is poor, although the cost is slightly lower, but the failure rate will be much higher, even if the manufacturer is also timely repair delay production.
因而,工件形狀必定不是挑選功能差的噴槍的理由。況且在昊信優秀的本錢操控系統下,AK系列的噴槍現已完成了中高檔商品-等級低價格的性價比提高。信任可以滿意廣大 用戶兄弟出產及本錢等多方面的請求。
Therefore, the shape of the workpiece must not be the reason for the poor selection of the spray gun. In the cost control system of excellent Haoxin, AK series of gun has been completed in the price of luxury goods - low level of price increases. Trust can be satisfied with the majority of users, brothers and other aspects of production and capital requirements.
濟南氟碳噴涂誤區三:噴槍出粉量越大,上粉率越高,作業越快。
Ji'nan fluorocarbon spray error three: the larger the amount of powder spray gun, the higher the powder rate, the faster the operation.
疑問剖析:
Question analysis:
1.在長時間作業過程中,咱們遇到不少用戶提出噴槍出粉越大必定上粉越好。實踐上,噴槍的上粉率是由靜電功能和出粉狀況一起決議的。只有電場強度與出粉量到達最好配合點的情況下才干完成最好上粉率。
1 in the course of a long period of time, we encountered a lot of users put forward the larger the powder spray gun powder must be better. In practice, the powder rate of the spray gun is determined by the electrostatic function and the powder output. Only the electric field strength and the powder to reach the best fit point in order to complete the best powder rate.
2.噴槍出粉過大必然會影響出粉狀況的均勻,這即是很多大粉量噴槍的出粉狀況很不均勻的根本原因。而欠安的出粉狀況則有也許形成涂層厚度不均勻的疑問。
2 spray gun powder is too large will inevitably affect the uniformity of the powder, which is a lot of large powder spray powder out of the situation is very uneven root causes. And had a powder state has perhaps the formation of uneven coating thickness in doubt.
3.經國外大量試驗數據及實踐作業經驗咱們可以得出噴槍的出粉量在450g/min就足作業需要了,更大的出粉量只會導致有一部分粉末根本無法帶電,沒有附著力,直接落入回收系統中,形成嚴重的糟蹋。
3 by a large number of test data and practical work experience we can draw the gun powder amount in 450g/min will need more homework, the powder amount will only lead to a portion of the powder cannot be charged, no adhesion, directly into the recycling system, causing serious waste.
4.功能優秀的噴槍恰是依據電場強度與出粉量的最好配比開發的,不光杜絕了不必要的糟蹋,更使出粉狀況均勻完美,愈加進步了上粉率。
4 excellent function of the spray gun is precisely based on the strength of the electric field and the best proportion of powder developed, not only put an end to unnecessary waste, but also the use of powder condition even perfect, more and more on the powder rate.
因而,出粉量不是越大越好,但也不是越小越好。一句話,最合適的才是最有價值的。
Thus, the powder is not the bigger the better, but not the smaller the better. In a word, the most appropriate is the most valuable.
濟南氟碳噴涂誤區四:誤以為噴槍噴出的粉末透明度低、直觀感受濃度大的噴槍出粉量大。
Ji'nan fluorocarbon spray error four: mistakenly believe that the spray gun powder transparency is low, intuitive feel a large concentration of large amount of powder spray gun.
疑問剖析:
Question analysis:
充電功能好的噴槍,因為可以給噴出的粉末顆粒充上充足的靜電電荷,從而使粉末顆粒之間取得滿足的相互間的靜電排斥力,這么的粉末脫離噴槍后粉末顆粒之間不粘連,呈
The charging gun function good, because it can give adequate filling powder electrostatic charge on the spray, so that the mutual electrostatic powder between particles get repulsive force, so the powder from the gun is not after the adhesion between powder particles, a
現出非常好的霧化狀況,從旁邊面看,會感到粉末均勻透明度高,形成“出粉少”的幻覺。而充電功能欠好的噴槍噴出的粉末,粉末顆粒之間沒有滿足的靜電排斥力,粉末顆粒之間成片粘連、霧化作用欠好,從噴槍的旁邊面看,噴出的粉末透明度低,往往形成“出粉多”的假象。
Shows a very good atomization, from the side to see, you will feel the uniform high transparency of powder, the formation of a powder less illusion. The charging function under the spray gun powder, does not meet the electrostatic repulsion between the particles of the powder, the powder particles between the film adhesion and atomization effect is not good, see from the gun beside the powder from the low transparency, often form "powder".
實踐證明,當用一樣的供粉量(同一套供粉設備、同樣氣壓條件、同一箱粉末)給充電功能不一樣的噴槍供粉時,充電不良的噴槍噴出的粉末從旁邊面看透明度低,直觀感受粉末濃度高;而充電功能優秀的噴槍噴出的粉末從旁邊面看則透明度高,直觀感受濃度低。
Practice shows that when used for the same amount of powder (with a powder supply equipment, same pressure conditions and the same gun powder box) to the charging function is not the same as for powder, spray gun charging bad powder from the side surface at low transparency, high powder concentration and intuitive feeling; excellent gun charging function spray powder from the side surface, high transparency, low concentration of intuitive feelings.
因而,出粉量一樣的兩把噴槍,充電功能越好的噴出的粉末霧化越好,旁邊面調查透明度越高,而并非旁邊面調查粉末透明度低、直觀濃度大的一把噴槍出粉量多。
Thus, the two gun powder like powder, the better atomization charging function better from the side surface, investigation of higher transparency, but not near surface investigation of powder low transparency, intuitive high concentration of a spray gun powder amount.
