Abstract

Kształtownik trzywarstwowy polimerowo-drzewny, otrzymywany w procesie współwytłaczania mikroporującego, charakteryzuje się tym, że składa się z trzech warstw: warstwy (1) zewnętrznej litej, warstwy (2) środkowej mikroporowatej i warstwy (3) wewnętrznej litej, z których warstwa (1) zewnętrzna lita i warstwa (3) wewnętrzna lita wytworzone są z poli(chlorku winylu) nieplastyfikowanego i mączki (4) drzewnej. Warstwa (2) środkowa mikroporowata wytworzona jest z poli(chlorku winylu) nieplastyfikowanego i mikrosfer (5) polimerowych. Sposób wytwarzania kształtownika trzywarstwowego polimerowo-drzewnego, charakteryzuje się tym, że do trzech układów uplastyczniających wytłaczarek posiadających cztery strefy grzejne, połączonych z głowicą wytłaczarską, dostarcza się tworzywo, przy czym do układu pierwszego i układu trzeciego zasypuje się poli(chlorek winylu) nieplastyfikowany i mączkę drzewną, zaś do układu drugiego zasypuje się poli(chlorek winylu) nieplastyfikowany i mikrosfery polimerowe.The three-layer polymer-wood profile obtained in the process of microporous coextrusion is characterized by the fact that it consists of three layers: the outer solid layer (1), the middle microporous layer (2) and the solid internal layer (3), of which the layer (1) the outer solid and the inner layer (3) are made of unplasticized polyvinyl chloride and wood flour (4). The microporous middle layer (2) is made of unplasticized poly (vinyl chloride) and (5) polymer microspheres. The method of producing a three-layer polymer-wood profile is characterized by the fact that up to three plasticizing systems of extruders having four heating zones connected to the extrusion head, material is supplied, while the first and third systems are filled with unplasticized polyvinyl chloride and flour wood, while the second system is filled with unplasticized poly (vinyl chloride) and polymer microspheres.
