Description

Viniplast - rigid thermoplastic opaque, free of the plasticizer, plast on the basis of polyvinylchloride and polyvinyl chloride post chlorinated, containing also thermo - and the light stabilizers, antioxidants preventing destruction of material during the processing and operation, greasing the substances (facilitating its processing and processing), pigments or dyes for receiving color products. Is polymeric product.

Other name - unplasticized polyvinyl chloride (NPVH).

For improvement of operational properties and reduction in cost enter up to 35% into structure of viniplast (from massypolimer) modifiers (halothene, rubbers), to 20% of fillers (chalk, soot, aerosil) and to 10% of plasticizers.

Viniplast it can be pasted to concrete, wood and metallic surfaces.

Viniplast not goryuch has also no smell. Besides, viniplast well gives in to different types of machining. Viniplast easily cooks at temperature of 230-250 degrees Celsius by means of welding bead and well sticks together with various types of the glues prepared on the basis of polyvinylchloride and polyvinyl chloride post chlorinated. It should be noted that welded and glue connections which durability makes 80-90% of material durability well give in to machining.

Viniplast is good dielectric at operation of products within +20-80 degrees Celsius, but it is necessary to consider that when heating viniplastovy product above +80 degrees Celsius come sharp falling of dielectric properties. Viniplast it is steady against effect of acids, alkalis and aliphatic hydrocarbons, but is unstable to effect of aromatic and chlorinated hydrocarbons.

It is applied to production of pipelines, tanks, sheets, profiles in construction, chemical mechanical engineering, etc.

As has good bending strength and elasticity, from viniplast sometimes in the handicraft way (switches) and winter rods-mormyshek rybakiizgotavlivat upper parts of fishing-rods of spinnings. At the corresponding processing such parts allow bend more than 45 degrees.

It is applied to production of facing and constructional elements for all industries applying acids, alkalis and the salts and their aqueous solutions and mixes and also some the organic compounds provided below. Temperature range of operation of sheets from 0 ° to +60 °C. When sheets are not exposed to mechanical influences, lower limit of operation to -50 °s.postavlyaetsya in sheets of 700х1500 mm in size and 2, 3, 4, 5, 8 and 10 mm thick is allowed. Also there are bars of d of 3 mm and with a section of 3х6 mm (packagings on 3 kg).

Table:

Physicomechanical properties (in accordance with GOST 9639-71):
Tensile strength, MPa, not less 50,0
Softening point on Vick, °C, not less 85
Change of the sizes at warming up, %, no more 5
Specific elongation at gap, %, no more 10

Viniplast it is chemically resistant to influence: sulphuric acid of 40% of concentration to 60 °C, oil of vitriol to 20 °C, nitric acid of 50% of concentration to 50 °C, mix of acids nitric and sulfuric, nitrous vitriols, off-gases (chlorohydrogen and chlorine in mix with air and water vapors), acetic acid of 100% of concentration, formic acid to 50% of concentration, phosphoric acid of the divorced and concentrated, sulphurous acid, alkali to 50% of concentration, ammonia, lime chloride, hydrogen peroxide of 10% of concentration, solution of the permanganate concentrated solution of salts of all types, ozone, acidic and alkaline sewage, etching acid to 40% at 20 °C, formaldehyde, hydrogen-sulfide water, carbon sulfur. Viniplast it is not soluble in: methyl and ethyl alcohol, the higher aliphatic alcohol, glycerin and other aliphatic polyols, aliphatic hydrocarbons, lubricating oils, vegetable oils.
