Description

Изобретение относитс  к способам изготовлени  фильтров, например, дл  гидротехнического строительства.The invention relates to methods for producing filters, for example, for hydraulic engineering construction.

Известен способ изготовлени  фильтров, заключающийс  в смешении измельченной древесины с полимерным св зующим и последующим отверждением и распалубкой отформованного издели .A known method of making filters involves mixing chopped wood with a polymer binder and then curing and stripping the molded product.

Цель изобретени  - получить материал с пористой структурой.The purpose of the invention is to obtain a material with a porous structure.

Это достигаетс  тем, что древесину предварительно увлажн ют, а затем смешивают со св зующим термопластичным, например полиэтиленовым , порошком и отформованное изделие подвергают нагреву до сплавлени  порошка с наполнителем.This is achieved by pre-moistening the wood and then mixing it with a thermoplastic binder, e.g. polyethylene powder, and the molded product is heated to fusion of the powder with the filler.

Слегка увлажненные древесные отходы (опилки) перемешивают с полимерным термопластичным порошком, а затем смесь загружают в формы и нагревают до температуры плавлени  порошка; после этого дают массе остыть и вынимают из формы готовый материал или отформованные .издели  в виде труб и других предметов. В процессе нагревани  смеси частицы термопластичного порошка спекаютс  в общую массу с порами и прочно св зывают опилки. При этом образуетс  пористый материал, обладающий прочностью до 8- 20 кг/см на сжатие и ко9ффи;циенто.м фильтрации до 15-40 ж/сутки.Lightly moistened wood waste (sawdust) is mixed with a polymer thermoplastic powder, and then the mixture is loaded into molds and heated to the melting temperature of the powder; after this, the mass is allowed to cool and the finished material or molded parts are removed from the mold in the form of pipes and other objects. In the process of heating the mixture, particles of the thermoplastic powder are sintered into the total mass with pores and the sawdust is firmly bonded. In this case, a porous material is formed, which has a strength of up to 8-20 kg / cm in compression and compression, a filtration cyentom up to 15-40 w / day.

Поры в теле материала образуютс  за счет частичного заполнени  порошком термопласта простр.анства между опилками, а также благодар  порообразованию при нагреве. Влажность способствует прилипанию частиц порошка к опилкам и равномерному распределению по всей массе.Pores in the body of the material are formed by partially filling the thermoplastic powder with space between sawdust, as well as due to pore formation during heating. Humidity promotes adhesion of powder particles to sawdust and uniform distribution throughout the mass.

Предмет изобретени Subject invention

Способ изготовлени  фильтров, напри.мер, дл  гидротехнического строительства путем смешени  измельченной древесины с полимерным св зующим и последующим отверждением и распалубкой отформованного издели , отличающийс  тем, что, с целью получени  пористой структуры, древесину предварительно увлажн ют, а затем смешивают с термопластичным св зующи.м, например полиэтиленовым порошком, и отформованное изделие подвергают нагреву до сплавлени  порошка с наполнителем .A method of making filters, for example, for hydraulic engineering construction by mixing crushed wood with a polymeric binder and subsequent curing and stripping of the molded product, characterized in that, in order to obtain a porous structure, the wood is pre-moistened and then mixed with a thermoplastic binder m, for example, polyethylene powder, and the molded product is heated to fuse the powder with the filler.
