双组份打胶机将导致局部电场强度极高、介质击穿、正负电荷中和、产生电火花,引燃或引爆有机溶剂气体,造成严重的人身设备安全事故.此种安全事故,在这一行业内时有发生.然各厂家在涂布生产时采用了各种不同方式的除静电措施,如离子流除静电器、机体.电源地线简单接地除静电措施等,这些措施有不同的消除静电作用,但都不能确保安全生产.

Will lead to high local electric field strength, dielectric breakdown, charge neutralization, spark ignition or detonation of organic solvent gas, causing serious safety accidents. The accidents in this industry have occurred. However, the manufacturers in production of coated by electrostatic measures in addition to a variety of different ways. Such as ion flow static eliminator, simple ground power ground body. In addition to static measures, these measures have different elimination of electrostatic interaction, but can not ensure the safety in production.

采用简单的接地电阻较高的机体.电源地线接地消除静电措施,在理论上局限于用欧姆定律:V=IR的观念.

Using a simple grounding resistance higher body. Grounding of power supply ground wire to eliminate electrostatic measures is theoretically confined to Ohm's Law: the concept of V=IR

生产现场中用静电测试仪测定的电压值虽为数千伏,但它是反映散布在纸、塑膜及各导辊所有表面静电荷的总能量状况,而每个瞬间能以导辊接触的物料表面上分散存在的静电荷的电压是有限的.分散在绝缘体上每个静电荷不可能经地线流人大地.

Voltage tester for electrostatic field values in the production although thousands of volts, but it reflects the spread in paper, plastic film and the guide roll all the electrostatic charges on the total energy, and every moment in the roller surface contact material dispersed on the voltage of electrostatic charge is dispersed in limited. Each static charge on insulator impossible by wire flow of the earth.

离子流除静电器一类措施,只适于消除被加工物表面已积累的静电荷,不能消除穿过后续导辊再产生的静电;尤其是涂布头附近空间导辊众多,空间有限,不便用这类除静电器除静电.

Ion flow static eliminator of a class of measures to eliminate static charge is only suitable for processing on the surface have been accumulated, can eliminate static electricity generated through the subsequent guide roller; especially the coating head space near the guide roller is numerous, the limited space, inconvenient use this kind of static eliminator eliminates the static electricity.

在双组份打胶机生产过程中,被加工的纸或塑膜类物料及涂布机各类导辊会产生大量静电,而不少生产工艺须使用低沸点、易挥发的易燃易爆的有机溶剂,如甲苯、溶剂汽油及各种酮类、酯类溶剂,产生大量易燃易爆熔剂气体.若消除静电措施不当,随着静电荷不断积累。

In two-component glue machine in the production process, the processed paper or plastic film material and all kinds of roller coating machine will produce a large number of static, organic solvents and many production processes must be using low boiling point volatile, flammable and explosive, such as toluene, solvent gasoline and various ketones, esters solvent, resulting in a large number of flammable gas flux. If the electrostatic elimination measures properly, with the accumulation of electrostatic charge.
