Ukucubungula umjovo wepulasitiki
Yimaphi amapharamitha wenqubo yomjovo oyinhloko wobuchwepheshe bokucubungula umjovo wepulasitiki?Ukuhamba kwezinto.Izinguquko enqubweni yokuncibilika kokugeleza / ukuncipha / ukuqina.Inkosi kulesi sigaba kufanele ibe nombono ukuze ibone ngoshintsho lwezinto ezincibilikayo emshinini / isikhunta.Kanjani?Kuyoba kuphi ukucindezeleka ngemva kokuncipha?Indlela yokudlulisa ukushisa?Kungani kunengcindezi yangaphakathi?Kuzokwenzekani?Leli khono yilapho lo mbuso uphakeme kunowangaphambili.Uma indawo yesithathu ibonakala inezinkomba ezimbalwa ezinkomba eziningi ezivela ngaphandle kuya ngaphakathi, indawo evela ngaphakathi kuya ngaphandle, lapho i-defect ehambisana nomdwebo we-fishbone ayisho lutho, futhi imingcele iba lula kakhulu.Lapho ucubungula isikhunta sepulasitiki, ukucindezela okukhulu emuva kungabangela izinkinga ezilandelayo:
Ingcindezi yokuncibilika phambi komgqomo iphezulu kakhulu, izinga lokushisa lempahla liphezulu, i-viscosity iyancipha, izinto ezincibilikisiwe zigeleza zibuyela ku-screw groove, ukugeleza kokuvuza kwamanzi phakathi komgqomo negebe lesikulufa kuyanda, nokusebenza kahle kwepulasitiki. (inani lezinto ezingenziwa ipulasitiki ngesikhathi seyunithi) liyancipha.
Kumapulasitiki anokuqina okushisayo okuphansi (okufana ne-PVC, i-POM, njll.) noma ama-colorants, izinga lokushisa elincibilikayo liyakhuphuka futhi isikhathi sokushisa komgqomo siyanda, okuholela ekwandeni kokubola okushisayo noma ukuguquguquka kombala, kanye nokuncipha kombala / isicwebezelisi indawo yomkhiqizo.
Ingcindezi yangemuva iphezulu kakhulu, isikulufu siyahlehla, isikhathi sokushajwa kabusha kwepulasitiki side, isikhathi somjikelezo siyakhula, nokukhiqiza kuyehla.
Ukucubungula isikhunta sepulasitiki
Ingcindezi yangemuva iphezulu futhi ingcindezi yezinto ezincibilikisiwe iphezulu.Umbhobho ujwayele ukuncibilika uma usujovwe.Lapho okunamathelayo kufakwa ngokuzayo, into ebandayo kumzila we-nozzle izovela amachashaza ezinto ezibandayo kubhobho noma umkhiqizo.
Enqubweni yepulasitiki kabhiya, ingcindezi yangemuva inkulu kakhulu, umlomo wombhobho uyavuza, umosha izinto ezingavuthiwe, futhi indandatho yokushisisa eduze nendawo yokungena ishisa kakhulu.
Lapho ucubungula isikhunta sepulasitiki, ingcindezi yangemuva eyeqile izokhuphula ukugqokwa kwemishini komshini wangaphambili wepulasitiki kanye ne-screw barrel.
