Ukulungiswa kwesitofu seplastiki
Zeziphi iiparamitha eziphambili zenkqubo yokutofa yeteknoloji yokusetyenzwa kwenaliti yeplastiki?Ukuhamba kwezinto.Utshintsho kwinkqubo yokunyibilika kokuhamba / ukucutheka / ukuqina.Inkosi kweli nqanaba kufuneka ibe nombono ukuze ibone ngokutshintshwa kwezinto ezinyibilikayo kumatshini / ukubumba.Njani?Uxinzelelo luya kwenzeka phi emva kokuncipha?Indlela yokudlulisa ubushushu?Kutheni kukho uxinzelelo lwangaphakathi?Kuya kwenzeka ntoni?Obu buchule kulapho lo mmandla uphezulu kunommandla wangaphambili.Ukuba indawo yesithathu ibonakala inezibonakaliso ezimbalwa kwiimpawu ezininzi ukusuka ngaphandle ukuya ngaphakathi, indawo ukusuka ngaphakathi ukuya ngaphandle, apho i-defect ehambelana nomzobo we-fishbone ayinantsingiselo, kwaye iiparitha ziba lula kakhulu.Xa kusetyenzwa ukubumba kweplastiki, uxinzelelo olugqithileyo ngasemva lunokubangela ezi ngxaki zilandelayo:
Uxinzelelo lokunyibilika phambi kombhobho luphezulu kakhulu, ubushushu bezinto eziphathekayo buphezulu, i-viscosity iyancipha, izinto ezityhidiweyo zibuyela emva kwi-screw groove, ukuhamba kwamanzi okuvuza phakathi kombhobho kunye ne-screw gap iyanda, kunye nokusebenza kakuhle kweplastiki. (ubungakanani bezinto ezinokuthi zenziwe ngeplastiki ngexesha leyunithi) ziyancipha.
Kwiiplastiki ezinozinzo oluphantsi lwe-thermal (ezifana ne-PVC, i-POM, njl. njl.) okanye i-colorants, iqondo lokushisa lokunyibilika liyenyuka kwaye ixesha lokufudumeza komgqomo liyenyuka, okukhokelela ekwandeni kokubola kwe-thermal okanye ukuguquguquka kombala, kunye nokuncipha kombala / isicwebezelisi. umphezulu wemveliso.
Uxinzelelo lwangasemva luphezulu kakhulu, i-screw ibuyela umva, ixesha lokutshaja iplastiki yangaphambili lide, ixesha lomjikelo liyenyuka, kwaye imveliso iyancipha.
Ukusetyenzwa komngundo weplastiki
Uxinzelelo lwangasemva luphezulu kwaye uxinzelelo lwezinto ezinyibilikisiweyo ziphezulu.Umbhobho udla ngokuba ne-drool enyibilikayo emva kokutofwa.Xa i-adhesive ifakwe kwixesha elizayo, izinto ezibandayo kwijelo lombhobho ziya kubonakala amabala abandayo ezinto ezibandayo kwi-nozzle okanye imveliso.
Kwinkqubo yeplastiki yebhiya, uxinzelelo lwangasemva lukhulu kakhulu, i-nozzle ivuza, ilahle izinto eziluhlaza, kunye neringi yokufudumeza kufuphi nendawo yokungena ivutha kakhulu.
Xa kusetyenzwa nokungunda kweplastiki, uxinzelelo olugqithileyo ngasemva luya konyusa ukunxitywa koomatshini beplastiki yangaphambili kunye ne-screw barrel.
