Windshield washer fluid is used while cleaning the windshield with the windshield wipers when the vehicle is being driven. In summer, drivers use water to clean the windshield, but in winter they have to seek other options. The use of non-freezing washer fluid is considered to be the best option in winter.
Since good driver visibility is essential for safe driving, many drivers are concerned about the principles of windshield washer fluid production. It is no wonder because the faster the product is sold, the more attention is focused on its production technology.
The following is a discussion of the core principles of windshield washer fluid production. First, there will be a need for specially purified water to produce windshield washer fluid. Particular attention therefore, should be paid to the water supply. There are powerful reagent filters that used for cleaming the water that is used in making the fluid. These powerful filters are very good at removing the different additives, mineral salts and bacteria from the water.
The next stage is decontamination and purification. The water is distilled in the course of the filtration process. The typical factory requires between five to ten square meters (5-10m3) of water a day to produce windshield washer liquids in commericl quantities. Additionally, there also may be needed the surface-active agents. Theses surface active agents are special chemical compounds that can collect all the dirt from the windshield. Commonly, the typical factory produces both winter and summer windshield washer liquids. If the other kind of windshield washer fluid is going to be produced, the storage tanks should be washed. In such a way, the quality of non-freezing fluid will be preserved.
Almost all processes need to be automated in order to reduce labor costs and time consumption. These processes include:
(1) molding of containers, caps, and skeeps;
(2) bottling;
(3) capping;
(4) labeling; and
(5) warehousing.
While designing the container for windshield washer fluid, the producer should think first about the user: it should be easy for the user to fill the washer reservoir. Such technology as vacuum shaping has been used to form containers. The special equipment, known as injection molding machines, provide for the production of caps and skeeps. Each item is produced by a specified molding tool as there is no such a machine that can produce caps and skeeps at the same time.
At the next stage, the containers are filled with washer fluid and then capped. While traveling along the conveyor, the capped containers are labeled.
Each label must contain the following information:
(1) date of manufacture;
(2) expiration date;
(3) name of the manufacturer; and
(4) conformance certificate.
Usually, the quality of the products are controlled by the testing laboratory that has an internationally recognized accreditation. The basic components of the washer fluid such as alcohol, glycol, and flavoring agents are measured by the refractometer. Each batch of alcohol is tested directly at the factory where it is produced.
