Bitumen Lukoil BN 90/10, BN 90/30 brand

Bitumen oil is produced by oxidation of products of direct distillation of oil and selective division of oil products, and also compounding of the oxidized and unoxidized products or in the form of the rest of direct distillation of oil. Bitumen represents extremely complex mix of hydrocarbons and heteroorganic compounds of a various structure which is generally not boiling away at oil distillation temperatures. Identification of all connections making bitumen is impossible. The group composition of bitumen predetermines its colloidal structure and rheological behavior and by that — technical properties which are characterized by the conditional indicators of quality defined in standard conditions. Among these indicators the major: a penetration (depth of penetration of a needle into bitumen), temperatures of a softening and fragility, a duktilnost (tensile properties) — ability of bitumen to stretch in a thread. Some indicators define both for initial bitumen, and for bitumen after warming up which imitates aging process. Standards set certain values of indicators of quality that reflects optimum composition of bitumen. This structure can be various for different scopes of bitumens.

The domestic industry develops the wide range of bitumens: road, construction (industrial) and roofing.
Construction BN 90/10 and BN 70/30 bitumens find application in such processes as a waterproofing of concrete constructions and the bases, the preliminary ogruntovaniye of the bases under a soft roof, besides, these bitumens is actively used in the course of production of bituminous and polymeric mastics for a waterproofing, a bituminous primer, a gidrostekloizol and some other construction materials.

One of secrets of continuous growth of popularity of bituminous mastic for a roof when carrying out many construction works is low cost of this type of a waterproofing. The main directions of use of bitumen - and it is repair of a roof and a bituminous waterproofing of the bases, - cause need for large volumes of this material, it, in turn, leads large purchases.
The BN 90/10 and BN 70/30 construction bitumens are characterized by all necessary qualities and provide high protection of various designs against an adverse effect of external environment, including, their application guarantees a qualitative bituminous waterproofing and creation of the additional field of protection against continuous mechanical influences. The indicators characterizing quality of bitumen: penetration (depth of penetration of a needle into bitumen) and softening temperature. A penetration at 25 °C, 0,1 mm: Bitumen 70/30 = 21-40, Bitumen 90/10 = 5-20, Temperature of a softening, °C: Bitumen 70/30 = 70-80, Bitumen 90/10 =90-105.

The BN 90/10 and 70/30 state standard specifications 6617-76 construction bitumens are packed up in in briketaa on 25 kg, bags on 39.5 kg and bays on 250 kg.
