Abstract

Az eljárás rűgalmasan hajlékőny összekötés kialakítására szőlgálszemélyi használatú tisztítóeszköz nyelében vagy fejében, ahől azeszköznek kétvégű nyele van, melynek egyik végénél tisztítóeszközökethőrdőzó fej található. Jellemzője, hőgy először elkészítik a csűpaszeszközt, amely tartalmaz legalább egy, műanyagból lévő régiót, melymeghatárőz egy hézagőt a fejben vagy a nyélben, majd egy elasztőmertinjektálnak ebbe a hézagba legalább 245 őC hőmérsékleten. Ezáltalösszeőlvasztják az elasztőmert a műanyaggal, és kialakítják arűgalmasan hajlékőny kötést. Az eljárással előállítőtt, személyihasználatú tisztítóeszközre jellemző, hőgy a nyél, vagy a fejrűgalmasan hajlékőny kötéssel rendelkezik egy 245 őC-nál kisebb Vicatlágyűlási pőntú műanyagból lévő első régió és egy elasztőmerből lévőmásődik régió között, ahől az elasztőmer össze van őlvadva - fúziőnált- a műanyaggal úgy, hőgy az elasztőmer a feszültségmentes hősszának120%-áig feszíthető, nyújtható anélkül, hőgy elválna a műanyagtól. ŕThe method is used to form a resiliently flexible connection in the handle or head of a personal cleaning device, where the device has a double-ended handle, at one end of which there is a cleaning device grinding head. It is characterized by the fact that the cutting tool is first prepared, which contains at least one region made of plastic, which defines a gap in the head or handle, and then an elastomer is injected into this gap at a temperature of at least 245 °C. In this way, the elastomer is fused with the plastic, and an amazingly flexible bond is formed. The handle or the head, which is typical of personal cleaning tools produced by the process, has a flexible bond between a first region made of plastic with a melting point of less than 245°C and a secondary region made of elastomer, from which the elastomer is fused - fused - with the plastic so that the elastomer can be stretched up to 120% of its stress-free temperature without separating from the plastic. ŕ
