Description
Изобретете относитс к снособу изготовле11и труб, примен емых в строительстве.The invention relates to a method for manufacturing pipes used in construction.
Известен способ изготовлеии труб путем ир мой иавивки, например, бумажной леиты и термоиластнчной плепки на оправку и тепловой обработки.There is a known method for manufacturing pipes by irradiating, for example, paper leita and thermo splicing on the mandrel and heat treatment.
Недостатком известного способа вл етс сложность технологического процесса и невысока прочность и долговечиость труб.The disadvantage of this method is the complexity of the process and low strength and durability of pipes.
С целью повышени физико-механических свойств трубы но предлагаемому сиособу теиловую обработку ведут одновременно с навивкой под давлением в иитервале температур в зкотекучего состо 1пи термопластичной пленки, а первый и последний слои наматывают из термопластичной пленки.In order to improve the physicomechanical properties of the pipe, but the proposed sioob method, the teil treatment is carried out simultaneously with the winding under pressure in the temperature range in the flowing state of the thermoplastic film, and the first and last layers are wound from a thermoplastic film.
На чертеже изображена схема, по сн юща предл-агаемый способ.The drawing shows a diagram explaining the proposed method.
На оправку 1, над которой расположен нагревательный элемент 2, наматывают термопластичную пленку 3 в иесколько слоев. Затем на пленку накладывают, например, бумажную ленту 4 и производ т навивку на оправку до образовани требуемой толщины стенки трубы . Далее подачу бумажной ленты прекращают , а навнвку термоиластпчной пленкиOn the mandrel 1, above which the heating element 2 is located, wind thermoplastic film 3 into several layers. Then, for example, a paper tape 4 is applied onto the film and wound on the mandrel until the desired wall thickness is formed. Next, the feeding of paper tape is stopped, and the thermal tape film
продолжают до образовани нескольких слоев. Намотку всех слоев от первого до последнего производ т при посто нном давлении в интервале температур в зкотекучего состо ни пленки. После снижени температуры иавитой трубы, наиример отведение нагревател , трубу снимают с оправки.continue until several layers form. All layers from the first to the last are wound under constant pressure in the temperature range in the flowing state of the film. After the temperature of the Iabita pipe has decreased, the heater is removed, the pipe is removed from the mandrel.
В результате одновременного воздействи температурь п давлени на термопластичную плеику Н бумагу образуетс монолитна комиознц-н стенки трубы.As a result of the simultaneous effect of temperature and pressure on the thermoplastic pleica of H paper, monolithic cumulative pipe walls are formed.
Предмет изобретени Subject invention
1.Способ изготовлени труб путем пр: мой навивки, иагфимер, бумажной ленты т термопластичной пленки на оправку и тепловой обработки , отличающийс тем, что, с целью повыщени физико-механических свойств трубы , тепловую обработку ведут одновременно с под давлением в интервале температур .в зкотекучего состо ни термопластичной пленки.1. Method of manufacturing pipes by way of: my winding, molding, paper tape and thermoplastic film on the mandrel and heat treatment, characterized in that, in order to enhance the physical and mechanical properties of the pipe, heat treatment is carried out simultaneously with the pressure in the temperature range. The flowing state of the thermoplastic film.
2.Способ ио п. 1, отличающийс тем, что иер.вый и иоследний слои наматывают из термопластичиой пленки.2. Method of Claim 1, characterized in that the upper and the last layers are wound from a thermoplastic film.
