“…После впрыска материала через сопло в пресс-форму и выдержки его под давлением, шнек в процессе постоянного вращения передвигается назад в исходное положение. Такой принцип работы агрегата обеспечивает минимальное время нахождения полимерного материала в материальном цилиндре, способствуя тем самым увеличению производительности оборудования [7].…”

“…Влияние давления литья в данном случае сказывается в основном на увеличении скорости впрыска и уплотнении полимерного изделия в пресс-форме до его затвердевания. Образование мелкосферолитной структуры в полимерных материалах всегда положительно сказывается на повышении их прочностных характеристик [6,7].…”

“…Следует при этом отметить, что в процессе литья и перемешивания расплава полимера в материальном цилиндре в нем могут протекать различные структурные изменения, включая механо-деструкцию и сшивание макромолекул, сопровождаемое окислением [7]. Кроме того, в процессе впрыска полимерной массы в формующую часть пресс-формы могут протекать следующие процессы: ориентация макромолекул, неравномерное протекание процесса кристаллизации на поверхности изделия и в его объеме, возникновение внутренних напряжений в результате деформации валентных углов и изменения размера макроцепей [12].…”

“…The authors [50][51][52][53] have established that the availability of nanoclay in the composition of natural mineral fillers (vesuvianite and CLT) leads to essential improvement of rheological properties (shift rate) of the polymer composites on the basis of BEP and REP in 2.8 times. The flow curves and melt viscosity of the initial REP and its filled composite were investigated.…”

“…The influence of temperature regime on pressured strength properties and volumetric shrinkage of polymer nanocomposites on the basis of REP and BEP and mineral fillersvesuvianite and CLT was analyzed. It revealed that comparatively high values of strength properties of nanocomposites on the basis of BEP +5% mass vesuvianite and BEP+10% mass of CLTs was fixed at a temperature regime of material sylinder 160-180-195-210°С, holding time under pressure 20 sec., and a mold temperature 50°С [51].…”

The work deals with the results of analytical review of the development and research of polymer composite materials with improved electro-physical and physical-mechanical properties. It found that the selection of special fillers, their variation by quantity and particle sizes in the polymer matrix can essentially affect the electro-conductivity of material and thereby regulate their electret properties on the whole. It revealed that the use of traditional fillers of carbon-black, graphite, minerals, metals, etc. in the composition of thermoplastics, reactoplastics and rubber makes it possible to prepare antistatic products, electromagnetic protective coatings, resistors, various types of current-conducting materials. The use of various lightweight fillers allows preparing lowdensity composites with higher physical-mechanical and electret properties. The spheroplastics based on siloxane elastomer began gaining a larger popularity. There is the data on carbon-blackfilled composite materials based on polyolefins which, at definite ratios, allow preparing the electroconductive products. A certain place in the review is given to the use of highly dispersed metal powders for the improvement of the electret characteristics of composites. Much attention is paid to the investigation of nanofilled composites with the use of large set of the dispersed minerals. The use of hybride polymer nanocomposites opens up new perspectives for their wider use in the production of current-conductive materials. The possibility of chemical binding of mineral filler particles with polymer matrix using the binders with conjugated double bonds provides innovative approaches to the creation of high-strength and heat-resistant electroconductive composites. It becomes obvious that the most perspective direction of preparation of materials with high electret properties must be based on mechanical-chemical synthesis of composite materials.
