Для повышения износостойкости полимерных форсунок в композит внедряют дисперсные наполнители. Композит для распылителей сельскохозяйственных опрыскивателей должен отличаться высокой химической стойкостью к агрохимикатам и механической прочностью, а также низким гидроабразивным износом. С целью выбора оптимального полимерного композита для распылителей сельскохозяйственных опрыскивателей изготовлены три композита на основе полиоксиметилена марки MASCON POM 27, в которых в качестве дисперсных наполнителей использовались стекловолокно, графит и карбид кремния со степенью объемного наполнения 10, 15 и 20%. Полимерные композиты исследовались в течение 14 недель на химическую стойкость к агрохимикатам (гербицид «Лазурит», фунгицид «Ракурс», инсектицид «Борей-Нео»), механическую прочность и гидроабразивный износ. В качестве эталона выступали образцы из полиоксиметилена марки MASCON POM 27. Результаты испытаний на механическую прочность при растяжении показали наибольшее увеличение показателя прочности при 15%-ном содержании наполнителя независимо от его типа. Прочность композита с карбидом кремния увеличилась на 30,2%, со стекловолокном – на 26,8%, с графитом – на 27,4%. Установлено, что химическая стойкость композитов не зависит от концентрации раствора агрохимикатов. Экспериментами по гидроабразивному износу выявлено, что графит и карбид кремния эффективны как наполнители и способны снизить износ до 7,5 раза. Для изготовления распылителей сельскохозяйственных опрыскивателей рекомендуется применять полиоксиметилен с 15%-ным содержанием карбида кремния.</p></abstract><trans-abstract xml:lang="en"><p>The long service life of a farm sprayer depends on the material, the nozzles are made of. To increase the wear resistance of polymer nozzles, dispersed fillers are incorporated into the composite. Composites for agricultural sprayer atomizers should have high chemical resistance to agrochemicals and mechanical strength, as well as low hydro-abrasive wear. In order to select the optimal polymer composite for farm sprayer atomizers, three composites based on polyoxymethylene of MASCON POM 27 brand were produced, in which glass fiber, graphite and silicon carbide with the degree of volume filling 10, 15 and 20% were used as disperse fillers. The polymer composites were tested for 14 weeks for chemical resistance to agrochemicals (herbicide “Lazurit”, fungicide “Rakurs”, insecticide “Borei-Neo”), mechanical strength and hydro-abrasive wear. MASCON POM 27 polyoxymethylene samples served as a reference. The results of mechanical tensile strength tests showed the greatest increase in the strength index at 15% filler content regardless of its type. The strength of the composite with silicon carbide increased by 30.2%, with glass fiber – by 26.8%, with graphite – by 27.4%. It was found that the chemical resistance of composites does not depend on the concentration of agrochemical solution. The experiments on hydro-abrasive wear revealed that graphite and silicon carbide are effective as fillers and can reduce wear up to 7.5 times. It is recommended to use polyoxymethylene with 15% content of silicon carbide for manufacturing farm sprayer atomizers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>композит для распылителей сельскохозяйственных опрыскивателей</kwd><kwd>полиоксиметилен</kwd><kwd>композит</kwd><kwd>дисперсный наполнитель</kwd><kwd>испытания</kwd><kwd>распылитель</kwd><kwd>химическая стойкость композитов</kwd><kwd>износостойкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composite product for farm sprayer atomizers</kwd><kwd>polyoxymethylene</kwd><kwd>composite</kwd><kwd>dispersed filler</kwd><kwd>tests</kwd><kwd>atomizer</kwd><kwd>chemical resistance of composites</kwd><kwd>wear resistance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Колесников А.В., Харина М.В.
