Ii-extruder ze-twin screw zisetyenziswa kakhulu ekuguquleni ii-polymers ngokwasemzimbeni, kwaye zingasetyenziselwa ukukhupha iimveliso ezibunjiweyo. Iimpawu zayo zokutya zingcono, kwaye inemisebenzi engcono yokuxuba, yokungenisa umoya, kunye nokuzicoca kune-screw extruder enye. Ngokudityaniswa kweentlobo ezahlukeneyo zezinto ze-screw, i-extruder ye-twin-screw enomsebenzi wokukhupha umoya eyilwe ngendlela yeebhloko zokwakha ingasetyenziswa kwezi zinto zilandelayo.
- Imveliso ye-masterbatch
Umxube wee-particles zeplastiki kunye nezongezo yi-master batch. Izongezo ziquka i-pigments, i-fillers kunye nezongezo ezisebenzayo. I-extruder ye-twin-screw sisixhobo esiphambili somgca wokuvelisa i-masterbatch, esetyenziselwa ukuhlanganisa, ukusasaza kunye nokuxuba izongezo kwi-polymer matrix.
- Uhlengahlengiso lokuxuba
Nika ukusebenza kakuhle kokuxuba phakathi kwe-matrix kunye nezongezo, izizalisi. I-fiber yeglasi yeyona nto ibalulekileyo yokuqinisa, kodwa ezinye iifayibha zinokudityaniswa nezithwali ze-polymer. Ngokongeza iifayibha kunye nokudibanisa nee-polymers, izinto ezinamandla aphezulu kunye nokumelana okuphezulu kwempembelelo zinokufunyanwa, kwaye kwangaxeshanye, ubunzima kunye neendleko zinokuncitshiswa.
- Umphunga
Ngenxa yokudibanisa ii-screws ezimbini, inkqubo yokucheba izinto kwindawo yokufaka ii-mesh ihlaziya rhoqo umaleko womphezulu wezinto kwaye iphucula isiphumo sokukhupha umoya, ukuze i-extruder enezikrufu ezimbini isebenze ngcono kune-extruder enezikrufu esinye ephelelweyo.
- Ukukhupha ngokuthe ngqo
I-extruder enezikrufu ezimbini ingadibanisa ukuxuba kunye nokubumba i-extrusion. Ngokusebenzisa intloko ethile kunye nezixhobo ezifanelekileyo ezisezantsi, inokuvelisa iimveliso ezigqityiweyo ngendlela efanelekileyo, njengeefilimu, iipleyiti, iipayipi, njalo njalo. I-extrusion ethe ngqo ingashiya amanyathelo okupholisa kunye nokuphosa i-pelletizing kunye nokuphinda kufudumale kunye nokunyibilikisa, kwaye izinto ziphantsi koxinzelelo oluncinci lobushushu kunye noxinzelelo lwe-shear. Yonke inkqubo inokonga amandla kwaye ifomula inokulungiswa ngokulula.
