Therefore, this paper production technology is very simple. How to make new paper from used paper? Waste paper, such as newspapers or books, is a secondary raw material that can be recycled into packaging or paper towels. How is new paper made from used paper? The production of recycled paper looks different from the individual stages of new paper production. In recycling plants, special machines are used to crush, clean and mix with chemical additives. How is new paper made from recycled paper? In the technological process of recycled paper, during the processing of contaminated foaming pulp, chemicals such as ROKAnol® nonionic surfactants or products such as ROKAcet or ROKAfenol play a very important role. They are special agents with emulsifying, cleaning, degreasing, antistatic and defoaming properties. Additionally, other additives such as adhesives, chalk or bleaches ( sodium hypochlorite , soda bleach ) are added to the pulp . As we can see, paper production is a complex process that has been subject to continuous improvement for centuries. Despite the development of new technologies and machines, the individual stages of paper production from wood, such as wood processing, delamination, boiling or pressing, remained unchanged.
In the case of raw material (waste paper), the crucial role is played by special chemicals designed to purify and condition the paper . However, we must keep in mind that in the case of small, garden pools, which are mainly used by children, it is better to use active oxygen. It proves to be good especially in maintaining water that is replaced regularly. Active oxygen is usually the only effective solution when the pool is used by people who cannot tolerate contact with chlorine. Water purified by active oxygen does not irritate the skin and does not cause itching. Multipurpose chemicals: what are they? Over the past few decades, pool chemical manufacturers have developed many interesting solutions and ready-to-use multipurpose pool water cleaners. They are CZ Leads generally available in the form of capsules, powders, liquids or tablets, containing: chlorine or active oxygen, anti-algae agents, anti-lime substances, pH regulators, water clarifying agents. In addition to their fungicidal and bactericidal properties, multipurpose pool chemicals also facilitate the binding process of dirt particles. This process is called flocculation and allows us to remove impurities safely and precisely, for example with the use of pool filters. Multipurpose pool chemicals are therefore a great solution for those who do not want to use several different products to maintain their home pool.
What to put in the pool: practical tips Continuous monitoring of pool water is crucial if we want to maintain its cleanliness and ensure safe swimming. If we are not sure what products to use for our pool water, we must pay attention to its color and smell: Green water requires the use of anti-algae and shock chlorination products, as well as pH regulators , yellow or orange colored water should be treated with L-ascorbic acid , If the water gives off a rotten smell, we must use shock chlorination or active oxygen. If the pool is used frequently, we must constantly monitor and check the pH level and chlorine content. If the pH is outside the range of 7 to 7.4, we must use appropriate positive or negative pH formulations. If we do not have time for daily maintenance of our pool, we must use floats (dispensers, metering buoys) that progressively release disinfectant and conditioning substances. They will help you achieve maximum effectiveness from chlorine. (Reducing the pH of the pool water also prevents the formation of lime deposits and clogging of the water filtration system.) How to increase the pH of water in a pool? This is done by using pH-plus products in powder or liquid form. They are special chemicals that eliminate corrosion inside the pool and eliminate the irritating odor of chlorine. How to neutralize chlorine in a swimming pool? When checking the level of chlorine in the pool water, it may turn out that its concentration exceeds the permissible limits. What to do then and how to remove chlorine from pool water? You can do this by using products whose names include phrases like 'chlorine stop' or 'antichlorine'. They are usually sold as granules that are easily soluble in water. How to reduce the chlorine level in a swimming pool? First you must dose the appropriate amount of chlorine stop or anti-chlorine granules and then prepare a container full of water. Pour the granules into the water, dissolve it and then pour it into the pool. After about 30 minutes, check the chlorine content again; If the concentration is still too high, repeat the procedure.
