How to solve the problem of bubbles after filling the glue?

How to solve the problem of bubbles after consolidation of glue: 

The main reason for causing bubbles when the glue filled is consolidated by the glue filling machine:

1. Air enters during stirring, and the air is not completely removed during the injection of the product and the entire hardener process. Phenomenon: Very small are the bubbles.

2. The reaction of moisture and hardener agent produces gas, phenomenon: Very large are the bubblesThe solution to the first cause of bubbles:
　　 It is recommended that after mixing the main agent and hardener agent together, use a double-liquid glue potting machine to vacuum it with a vacuum system.
　　Turn on the heating system of the glue filling machine, and preheating the product to be potted will let the air escape.

　　Harden the glue in a room with low temperature and humidity to let the air flee. 

The solution to the second cause of bubbles:

A. The main agent has been used many times, and moisture is mixed in each time during mixing. It may cause the bubbles when the lid of the package is not tightly closed. In order to find out the real reason, please follow the above instructions to mix the main agent and hardener agent in a dry cup and put it in an oven (60-80) to dry. If bubbles still occur, it means that the main agent has deteriorated at this time, so please do not use it again. 

B. The potting product contains too much moisture. It is recommended to re-test after preheating the product.

C, the surface of the mixture of the main agent and the hardener agent reacts with moisture in the surrounding air. If this is the case, please cure in a dry environment. If the product permits, it can be cured in an oven after heating,

D. The liquid main agent and hardener agent mixture may have been in contact with other chemicals (such as solvents, release agents, varnishes, glues, etc.) before hardener. Ensure that these substances are removed before the next test

The easiest way to solve the bubble filling is to use a vacuum filling machine. 

Vacuum glue filling machine is a kind of equipment for filling glue in a vacuum environment. Compared with ordinary glue filling machines, the biggest difference lies in the vacuum, that is, the glue is defoamed to ensure that there are no bubbles in the glue. The main application industries are LED flexible light bar industry, automobile ignition coil, LED power supply, etc.

There are currently two types of vacuum glue filling machines: one is a fully automatic vacuum filling machine, and the other is a semi-automatic one.

Automatic vacuum glue filling machine is to continuously defoam the glue, including the entire glue filling environment is carried out in a vacuum environment, that is, the robot part of the glue filling machine is made into a full vacuum environment. This kind of glue filling machine is generally used for the glue filling of ignition coils, dry-type transformers and medium and high voltage transformers, that is, the product glue should not have any air bubbles.

Evaporative air cooler from Home Appliances

Enviromental Evaporative AIR COOLERS from Home appliance

Eco-friendly  

Evaporative air coolers

designed by nature.....evaporative cooling systems(duct evaporative air coolers) was inspired from the natural process of a sea breeze.

The sea is fresh because hot air is moved by the wind across the surface of the water, causing some of that water to evaporate and absorb heat.

The air is cooled by this evaporation process to become a refreshing breeze , producing a source of clean, fresh and healthy air. Evaporative cooling systems provide a constant flow of natural, cool, clean, fresh air without the need to use gases harmful to the environment (CFC's etc). Evaporative Cooling has the following benefits over conventional cooling and climate control systems:

• Introduces 100% filtered, fresh and cool air from outside.
• doors and windows can stay open unlike fully air conditioned spaces.
• Maintains some moisture in the air, particularly beneficial to those people who suffer from allergies and asthma.
• Reduces fumes, particles in suspension and odours.
• Cooling capacity efficiency is increased as the ambient temperature rises.
• Low power consumption and operating costs, up to 80% more economical than conventional air conditioning equipment.
• Low power consumption and operating costs, up to 80% more economical than conventional air conditioning equipment.
• Reduces static electricity.
• Normally these types of evaporative cooling systems are around 20-25% of the capital cost of air conditioning.  

Evaporative cooling systems are a perfect solution for Large factories, industrial complexes, printing works, plastics and textile industries, laundries, farms and glasshouses, factory units, foundries and bakeries etc. According to the size of the project, evaporative cooling systems are fitted to the exterior of the building, either on the roof, the side walls or at ground level. A system of ductwork and air diffusers is then used to introduce the cool air precisely where it is needed.

The Problem -> As outside temperatures increase, buildings with inadequate ventilation become unbearably hot and stuffy. The problem is compounded in premises into which sunlight can penetrate causing a hothouse effect. Not only does this effect staff morale, but can lead to absenteeism, accidents as well as reduce productivity.

                                     

Air conditioning might seem the obvious solution, but it is expensive to install and maintain and requires doors and windows to be kept shut.

The Solution -> Based on 30 years experience, the technological advancement in

evaporative coolers

has set new standards in evaporative air cooling by providing improved air delivery and high cooling capacity.

                                            

     

Environmentally friendly, the

evaporation air cooler

is economic to install, cost effective to run, and in addition to consuming less energy than conventional air conditioning systems enables doors and windows to be left open. Because a constant natural flow of 100% fresh air is drawn into the building and then expelled, odours, germs and airborne contaminants are removed and not recirculated around the buildling due to the airflow exchange by Swamp air coolers.
