Предлагаемый епоеоб отиоенте к аебестоцементной нромышленностн и может быть использован ирн иронзводетве различното тппа изделий из аебестоцемеитных суспензий коицентрацин от 5 до 50%.5The proposed solution for the abestos-cement industry and can be used by various manufacturers of coicentricin aebestocomceite suspensions from 5 to 50% .5
Известен сиособ изготовлеип волокиистоцемеитпых изделий путем обработки подложки из растительных или минеральных термоиластнчиых волокон иаиесеиием на нее кле , а затем - тоикодисиерсного ю асбеста методом механической нлн электростатической набивки с последующими пзготовлеиием ткани, введеиием ее, например , в асбестоцемеитиую суспензию с последуюии- м формоваиием 1.1Г)Known is a method for manufacturing plastic products by treating a substrate of plant or mineral thermal fibers with an adhesive and then gluing it asbestos using mechanical electrostatic filling with electrostatic stuffing, followed by fabrication, inserting it, for example, into a sample. )
Такой сиособ иредусматривает исиользование в качестве иодложки волокннстых материалов, как иравило, cлaб(Jycтoйчнвыx к агрессивиой щелочной среде, возникающей в результате реакиии гидратаиии ие- 20 ментной составл ющей, н обесиечивает мо нотонно-иилнндрнческую форму модифицированных ннтей, не иозвол юихую максимально нсиользовать их армирующие сиособиости нз-за недостаточной ирочности 25 сиеидеии с гатрнней, требует доиолиительного оборудовани дл изготовлени тканей II иоследующего введени их в издели , ограничивает способы армировани межслойиым введеиием арматуры.зоSuch a method also considers the use of fibrous materials as iodoil, as iravilo debris, which is aggressive to an alkaline environment resulting from the repetition of the hydration and the 20 Because of the lack of iroacism of the 25th siedey with the gatrnios, it requires an additional equipment for the manufacture of fabrics II and their subsequent insertion into products, limits the methods of reinforcement Interconnection of rebar.zo
Целью изобретени вл етс повыщение прочностных свойств асбестоиементных изделий.The aim of the invention is to increase the strength properties of asbestos-diemone products.
1.1,ель достигаетс тем, что в способе изготовлени асбеетопементных изделий путем обработки волокон из термопластичного материала нанесением на них кле , а затем тонкодиснерсного асбеста, введени обработанных волокон в асбестоцемептную суспензию с иоследующим формованием клей нанос т на каироиовые волокна с образованием отдельных колег, вокруг них при соблюдении усло15ИЙ:1.1, spruce is achieved by the method of making asbestos-concrete products by treating fibers from a thermoplastic material by applying glue on them and then fine-dispersing asbestos, introducing the treated fibers into asbestos-cement suspension and then shaping the glue to apply on kairoi fibers with the formation of individual fibers around them subject to the following conditions:
« /а.; /г 0,8rf, ,," /but.; / g 0,8rf ,, ,,
где п - количество на каироновом волокне колец из кле с нанесенным на него тонкодисперсным асбестом;where n is the number of glue rings on the cairo fiber with fine asbestos applied on it;
L-длииа капронового волокна;L-length nylon fiber;
К - коэффициент, равный 0,27-0,41;K - coefficient equal to 0,27-0,41;
li - толщина кольца из кле с нанесенным на ноеледннй тонкодисиерсиым асбестом (рассто ние между новерхностыо волоюга и виещней иоверхностыо обода):li is the thickness of a ring of glue with deposited asbestos-deposited asbestos (the distance between the surface of the arc and the uppermost rim):
I/ - диаметр канроиового волокна;I / is the diameter of the canroic fiber;
1 -краевой уго.1 смачивани кле щим веществом поверхности волокна.1-edge edge.1 wetting the fiber surface with an adhesive.
При этом сиособе используют в качестве армирующего материала щелочестойкоеIn this case, as a reinforcing material, alkali-resistant materials are used.
