Abstract
Изобретение относитс к производству длинномерных изделий типа проволоки, узких лент и др. Изобретение позвол ет повысить качество покрыти и производительность процесса за счет способа получени покрыти на длинномерных издели х, заключающегос в нагрепе подготовленной металлической поверхности до 300-350°С в течение 3,0-4,0 с, нанесение вибровихревым напылением поливинилхлоридной композиции и последующей термообработке нанесенной композиции при 250-280°С в течение 1,5-2,0 с, а затем при 230-250°С в течение 9,0-12,0 с. 1 табл.The invention relates to the production of long products such as wire, narrow strips, etc. The invention improves the quality of the coating and the productivity of the process due to the method of obtaining the coating on long products, consisting in heating the prepared metal surface to 300-350 ° C for 3 , 0-4.0 s, spraying a polyvinyl chloride composition and subsequent heat treatment of the applied composition at 250-280 ° C for 1.5-2.0 s, and then at 230-250 ° C for 9 0-12.0 s. 1 tab.
Description
Изобретение относитс к производству длинномерных изделий типа проволоки, узких лент и др.The invention relates to the production of long products such as wire, narrow strips, etc.
Цель изобретени - улучшение качества покрыти и повышение производительности .The purpose of the invention is to improve the quality of the coating and increase productivity.
Способ осуществл ют следующим образом .The method is carried out as follows.
Проволоку, прошедшую ванну обезжиривани , нагревают в узле электроконтактного нагрева до 300-350°С в течение 3-4 с. а затем изделие поступает в камеру вибровихревого напылени , где на него нанос т слой порошковой полимерной поливинилхлоридной композиции и одновременно происходит перва ступень охлаждени проволоки до 280-250°С в течение 1,5-2,0 с. Далее проволока со слоем полимера проходит зону формировани покрыти при 230- 250°С, где за счет тепла, накопленного при предварительном нагреве, полимер расплавл етс с образованием ровного гл нцевого покрыти . Врем формировани покрыти 9-12 с. При этом проволока выдерживаетс при 250-230°С и при такой температуре идет в душирующее устройство и далее на намотку.The wire passed through the degreasing bath is heated in the electrocontact heating unit to 300-350 ° C for 3-4 s. and then the product enters the vibrating chamber, where it is coated with a layer of polymer powder polyvinyl chloride composition and at the same time the first step of cooling the wire to 280-250 ° C for 1.5-2.0 s. Further, the wire with a layer of polymer passes the zone of formation of the coating at 230-250 ° C, where, due to the heat accumulated during preheating, the polymer melts to form a smooth gloss coating. The formation time of the coating is 9-12 s. In this case, the wire is kept at 250-230 ° C and at this temperature it goes to the cooling device and then to winding.
Примеры осуществлени способа приведены в таблице.Examples of the method are given in the table.
