The polyurethane is strong in the griding resistance, oxygen and light resistant. In the Polish brown coal open pits the dumping method is through rubber rings on the all runners.
Heavy-duty polyurethane linings – track chain segments – palette truck wheel and roller linings – forklift truck wheel linings. The single belt conveyor is equipped with the power feed drums and strecher drums and in the great number of the runners.
Spray-on elastomers feature very short reaction times, which allows their users to quickly complete assignments and achieve acceptance. With its ability to adjust product properties by appropriate raw material poliuretnowe, thanks to proper technology and processes and use of dedicated equipment, ZPTS can offer a broad range of products with guaranteed repeatability, consistency and top quality.
ZPTS manufactures elastomer components from various types of systems: By utilizing over years of elastpmery experiences in polyurethane elastomers processing, ZPTS Poliuretany has expanded its business profile by offering the following polyurethane systems: The belt conveyors transport systems task elastomerry coal or soil transmission to the receiving dumpers.
At present, polyurethane is probably the most versatile material poliuretanowr. Depending on the composition and on the molecular weight of polyurethanes, they feature varied physical and chemical properties.
We are also manufacturing: Thanks to their properties, they can be used not only as substitutes for rubber products. Flexible, abrasion-resistant polyurethane linings – scoops – dumps – chambers – scrapers – combs – pumps and rotors – mills – honing machines – hydrocyclones – valves – drums. A castable polyurethane elastomer for standard applications. Polyurethane linings and jackets – drive shafts and tensioning rollers of belt conveyors – pulling rollers and supporting rollers – transport rollers and pressure rollers.
Flexible, abrasion-resistant polyurethane linings – curtains – strips – plates – seals and other products, which utilize properties of this plastic. A castable polyurethane elastomer in a softer adjustment.
Th elife durability of such runners is shorter then main runners. Because of the intermediate pourying points poliuretanowd belt conveyors tansport systems – the belt conveyors are working in the strong dynamical loads.
Thanks to their unique properties, polyurethane elastomers are used as superior alternatives to poliureatnowe products or products made of other polymers or metals. Suited for producing hollows or form parts in machine- tool- form- and mold-making, that are exposed to high pressures or abrasion.
It serves the production of long-lasting formliners for concrete elements with a large pattern depth or light undercuts. Due to their wide range of applications, PU elastomers are relatively small in terms of volume but very important group of polyurethanes. Polska Produkty Budowa modeli Elastomery poliuretanowe. Polyurethanes are polymers, which are obtained in result of a chemical reaction between aromatic or aliphatic isocyanates with compounds having at least two hydroxyl or amino groups.
In the modern machinery design the polyurethane elastomers PUR elements are employed. Spray-on elastomers processing requires qualified contractors and specialized equipment. They are oil, grease and fuel resistant too. Such characteristics will be suitable for the brown coal applications.
Such very good characteristics will give long durability in the open air work as the summary effecy. The polyurethane strength experimental research are shown.
Key features of polyurethane elastomers: Polyurethane shock absorbing elements – sleeves and rollers – springs – silentblocks – press fenders – vibrators – dampers. The basic machinery are comployed in the coal open pits are equipped with the internal belt conveyors transport and the outer belt conveyor transport system.
We are also manufacturing custom linings elasyomery rollers and cylinders, with specifications exceeding the above-mentioned values. The overall length of the conveyors transport system in the particular brown coal open pit is over km. A polyurethane elastomer for use in vertical and overhead areas.
Raw materials Due to their wide range of applications, PU elastomers are relatively small in terms of volume but very important group of polyurethanes. We are also offering professional mixing and dosing equipment for polyurethane elastomer processing. The paper presents suitability of the polyurethane elastomers PUR elements for the brown coal open pits machinery applications. Such broad range of MILPUR systems allows its users to optimize properties of elastomers so that they best suit the specific application.
After pooiuretanowe application, a relatively “heavy” solvent-free coating is obtained, which: It is suited especially well for producing long-lasting casing formliners for patterned exposed concrete elements.
The polyurethane machinery elements proof ground investigation research results are presented too. Heavy-duty polyurethane linings – track chain segments – palette truck wheel and roller linings – forklift truck wheel linings Polyurethane components with high dynamic ratings – membranes for hydrodynamic presses – clutch poliuretabowe – flexible clutch couplings – grading sieves Flexible, abrasion-resistant polyurethane linings – scoops – dumps – chambers – scrapers – combs – pumps and rotors – mills – honing machines – hydrocyclones – valves – drums Polyurethane shock absorbing elements – sleeves and rollers – springs – silentblocks – press fenders – vibrators – dampers We are also manufacturing: Combination of their strength and flexibility with the ability to create seamless coatings piliuretanowe particularly useful if used as waterproofing.
In the damage state they are the coal pits source. Can be applied as the Pure Casting Material 75, but differs in its degree of firmness. With the great thermal and chemical resistance they are placed on the rubber traditional positions. They permit production of components with exceptional technical properties, which can not be achieved with other types of elastomers.
