What are the characteristics of ROTO plastic tanks? Why is it safe for health?

Primary plastic water tank - Safe material for health

Today, health issues are always the top concern by affecting the quality of life and work. Households tend to use clean, safe products for health more. Understanding that problem, ROTO has also been contributing to promoting the use of clean and safe materials in its water tank and septic tank products.

Extracted from Primary Plastic, this is a type of plastic extracted from petroleum ore, unused and completely free of other impurities. Therefore, virgin resin has very high purity and impressive durability. This type of plastic is divided into many different types depending on the needs of use such as: PE, PP, ABS, PA, PVC, etc. For water tanks whose main material is plastic, PE is the type. most suitable for application in production because of many impressive properties:

• Durable
• High ductility
• Good impact resistance
• Resistant to environmental influences
• Plastic may not age if UV protection is added

However, PE resins that can have different molecular structure characteristics will be subdivided into many sub-branches to have selectivity in accordance with the desired characteristics from the manufacturer. Typical PE branches such as: LLPE, LLPDE, MDPE, HDPE, XLPE, UHMW. ROTO-branded water and septic tanks are manufactured by LLPDE.

Why does ROTO use LLDPE?

With ROTO products, LLDPE (Linear Low Density Polyethylene) plastic is considered the best quality and safest. In terms of characteristics, they have a considerable number of short branches. Because it has more and shorter branches, its chains can slide into each other when stretched out without entanglement e.g. LPDE has long branch chains that can entangle each other. This gives LLDPE higher tensile strength and greater resistance to impact and puncture than LDPE. The density falls in the range of 0.91-0.94g/cm3.

• Durability (homogenous single-layer): Only a single layer of homogenous primary plastic completely overcomes the uneven expansion of multi-layer plastic which is one of the causes of tank breakage, withstands environmental impacts . outside. such as: Weather (low humidity, high temperature, underground, hot dry ...) and impact (strong impact, scratches). LLDPEs multi-branch network makes the ROTO tank resistant to strong external and environmental influences over a long period of time.
• Safety: Because it does not dissolve in water, it is not corroded by alum salt water source, so it is very safe and does not cause harm to health and can contain some chemical solutions or can even be used to store tanks. food and raw materials.
• Superior bearing frame system: The new frame system of the primary plastic water tank increases the bearing capacity as well as distributes the force to withstand great pressure. Avoid fragile or leak inside.

Compared to other competitors in the tank manufacturing industry, ROTOs products are always durable because we do not use hard but brittle LPDE series PE plastic. Instead, the use of PE LLPDE plastic gives outstanding quality but is always affordable. In addition, the tiny plastic particles cannot be dissolved in water, so customers can be assured and satisfied with their health.

100% automatic revolving technology

ROTOs manufacturing process originates from Twin Rotary Casting Technology. Mixing method for mixing fuels in liquid form by high temperature. The auxiliary materials are ground into a fine powder. Therefore, the output product will have outstanding advantages compared to the dry mixing method such as:

• Liquefaction of primary resin and color helps resin and color to bond firmly, increase durability, gloss and contribute to anti-light penetration, preventing the formation of moss.
• UV is the main ingredient that must be liquefied with the above mixture to help prevent ultraviolet rays from entering the tub
• Colorants to form a mixture of secondary materials to produce a beautiful, long-lasting and aging product with a shelf life of over 60 years.

All production processes are controlled by an automatic control system (PLC): the elements of temperature, rotational speed, etc. according to each product volume are programmed and controlled to achieve the most optimal level by machining. Technology now ROTOMOUNDING BI-AXIAL. To be able to bring to the market, it also has to go through rigorous product quality checks. Finally, finish the exterior and package the product.

ROTO primary plastic water tank meets strict standards of international organizations

ROTO water tank is made from 100% virgin plastic - extracted from petroleum ore, without impurities. Besides, ROTO water tank products also meet strict standards in terms of safety and hygiene of domestic water sources. For that reason, international organizations have always trusted and used ROTOs water tank products, and ROTO has been accompanying international organizations such as: CARE, Save the Children, Novaland, Worldbank, Association, etc. Womens Union...
