May 2, Guangdong Dongguan a gift wrap box with lid plant fire, the main burning material for paper gift wrap box with lid packaging products;
May 17, located in Baoding City, a gift wrap box with lid packaging products Co., Ltd. within a plant suddenly caught fire ......
With the advent of summer, the temperature is rising, the need for the majority of printing gift wrap box with lid packaging paper enterprises to learn a lesson, according to the cause of the fire, to "human + physical + technical prevention", multiple initiatives to prevent to resolve the fire hazard. In addition to focus on production safety, printing gift wrap box with lid workshop in the high temperature environment also need to focus on what issues?
gift wrap box with lid paper is composed of plant fibers, plant fibers are porous and hydrophilic, very sensitive to water. A slight change in ambient temperature and humidity, gift wrap box with lid paper water content will change. Relative humidity of the air on gift wrap box with lid paper water content, generally is the relative humidity increases, gift wrap box with lid paper water content increases, and vice versa, the relative humidity decreases, gift wrap box with lid paper water content decreases.
And temperature changes for gift wrap box with lid paper moisture content of the impact of different. Generally, the temperature rises and the moisture content of gift wrap box with lid paper decreases. And gift wrap box with lid paper moisture content size, and gift wrap box with lid printing performance has a direct relationship. For example, gift wrap box with lid paper moisture content changes will cause paper stretching (including local deformation). gift wrap box with lid paper size stability and printing job suitability and register suitability has a great relationship.
Especially multi-color overprint products, gift wrap box with lid paper size changes, will cause the product overprint inaccurate, become inferior, scrap. Therefore, the paper is affected by temperature, humidity and size changes in gift wrap box with lid printing shop is one of the most important issues. As gift wrap box with lid paper moisture content changes, will also cause gift wrap box with lid paper other performance changes. Such as increased water content, gift wrap box with lid paper tensile strength, surface strength decline; water content is too low, gift wrap box with lid paper becomes brittle and hard, easy to produce static charge phenomenon when printing.
Various gift wrap box with lid printing ink by the temperature and humidity of the degree of influence varies. In general, the higher the temperature, the faster the drying; the lower the temperature, the slower the drying. Especially the lithographic printing process of ink, in gift wrap box with lid printing process, due to the presence of fountain solution, will cause emulsification, so the size of the relative humidity affects gift wrap box with lid ink in the evaporation of water. Therefore, temperature and humidity have a direct impact on the drying speed of the ink, if the temperature is too low, the relative humidity is too large, it will reduce the drying speed of gift wrap box with lid ink and prolong the gift wrap box with lid printing cycle.
The temperature and humidity of the environment will also affect the viscosity of gift wrap box with lid ink. Ambient temperature increases, gift wrap box with lid ink viscosity decreases; ambient temperature decreases, gift wrap box with lid ink viscosity increases. If the temperature is too low, gift wrap box with lid ink viscosity is too large, printing failures will occur, such as gift wrap box with lid paper surface local peeling, sticky blanket or printing plate. Therefore, control gift wrap box with lid printing shop temperature and relative humidity can control the drying speed of the ink, printing failure.
First, the production gift wrap box with lid of the mechanical parts of the wear and tear will increase;
Second, the impact on the electrical part of the production gift wrap box with lid more, printing gift wrap box with lid offset printing machine on the motor, air pump, oil pump control are through the thermal appliances as protection, the temperature is too high, there will be printing gift wrap box with lid machine overload protection action, affecting the normal work. Especially the main motor inverter to refuse high temperature, while high temperature can also cause a fire.
Temperature and humidity changes on gift wrap box with lid printing workshop has a greater impact on the normal production. Practice has shown that gift wrap box with lid printing workshop the best working environment temperature of 18 ℃ ~ 23 ℃, relative humidity of 55% to 65%, gift wrap box with lid printing enterprises can use dehumidification and humidification machine for the workshop to create a relatively stable temperature and humidity of the production environment.
gift wrap box with lid enterprises to timely for the "high" temperature response measures, for the sweltering gift wrap box with lid production workshop must do a good job of cooling, ventilation initiatives, which is not only for gift wrap box with lid printing This is not only to gift wrap box with lid printing supplies storage quality protection, but also to gift wrap box with lid printing production line staff body safety protection.
