METHOD OF MANUFACTURING BANDAGE OF RADIATION FOR CAR TIRES

In order to accelerate the impregnation, a diluent in the form of fluorocarbon acid is added to the impregnation bath (ii-K) bath. In addition, the b8c & nets network is impregnated before the impregnation process in a solvent, and the solution of the fioSaBrfHioT elastomer solution, which, after the HcnapesaiH solution, often remains on the fibers of the network; After the development of your own, I w w fillets are applied in 5% means.

As a fibergate fiber - podhodtsg, for example, pleshashsch-66. The prepared yarns (whom the fiber or KOHcrpyicuJsro net is cut along the ddtg by segments of dm) is smaller than ddagr of the corresponding wheels. Both free ends of the net strip can be, for example, connected to each other and, therefore, the network of gantries should be endless. Then, the infinite network, reduced in size, is stretched to the position of the injector & the Lenne, which has a distance equal to the idiom, tjBSJS. The fiber of the network is thus obtained by the spreader network. In this form, the network of immersion & as long as you dissolve in a solution, a volcanoed elastomer heated in a hot form; the intermediate spaces of the fibers are weighed. Then the impregnated network is kept on air / xe until sa isee 80% of the solvent is evaporated. The process of propulsion and repetition is repeated several times until If a thick layer of elastomer is available, it will not cover individual strands of fibers from all flops.

Oppies show that in particular the first Jipofiecc immersion can be accelerated, if it is related to a gel1) For a clear, external discharge surface, add a tool, hydrofluorocarbon acid,

The forming fibers are processed by the impregnation process in a solvent and desiccated, and paciBop is added to the seed solution with a chemical agent, part of which, after removing the remaining solvent, remains on the fibers.

The D1i1 of the most advanced uncleanerous mesh of the boggy fiber is extracted from the elastomer: on the outer surface of the fibers, before impregnation, it is applied to a treadmill. After the last process, the projection and evaporation of the rim of the edge, at least 80% of the spent private network is removed from the equipment and vulcanized in an aytoklavetorom steam. More than 6 liter of base volcanic sulphate at TCNfflepaTypa water aiaga is about 140 ° C. At the same time, spontaneous extraction of the solvent into an elastomeric coating, which gives a non-rubber-like surface layer, is not suitable, as a means of antislip,

With the pressure of the autoclave in the autoclave, residual amounts of solvent are decomposed in elastic form in the elastomer and later, when the elastomer forms a network structure and becomes sufficiently soft, then the MOI7T autogenous diffuses back. The mesh structure of the elastomer is no longer violated.

When processing mountains Shm nar in autoklaee in

the time of vulcanization of the elastomer also occurs thermofixing the fibers. As a result of the thermofusion process, the volcano, which flows simultaneously with the elastomer network formation, is completely free of directly bonding material capable of withstanding difficult operating conditions as a means of skid protection for an automobile ipt.

The anti-slip devices for car tires obtained on the basis of the proposed method were tested in poor road conditions (on snow, on ice, as well as on polluted and sandy areas). During long trials on dry roads, the speed was maintained at 80-100 km / h and a total of 1000 km was passed without signs of collapsing anti-slip devices. On the test, the speed of 160 km / h developed for a short time, and no significant unusual effect on the vehicle's driving performance was noticed.

The anti-skid device turned out to be stable in size even when it was worn out m half of its thickness.
