I-twin-screw extruder ihlukaniswe yaba uhlobo oluhehayo kanye nohlobo olungaheheki ngokuya ngokuma okuhlobene kwezikulufu ezimbili.Uhlobo lwe-mesh luhlukaniswe lwaba uhlobo lwe-mesh oluyingxenye kanye nohlobo lwe-mesh egcwele ngokwezinga le-meshing.I-twin-screw extruder ihlukaniswe yaba izinhlobo ezimbili: isikulufu esizungezayo esiqonde ngqo kanye nesikulufu esizungezayo esibuyela emuva ngokuya ngesiqondiso sokuzungezisa isikulufu.

Ngezansi, u-Xiaobian uzokunikeza isingeniso esifushane mayelana nezinkinga zobuchwepheshe zama-twin-screw extruder.

1. Khulisa isivinini se-screw, esivumela ukwakheka kwebhamuza, ukukhula nokuqhekeka, okuzuzisa ukunciphisa ubude bokugcwalisa bezinto ku-screw groove, uthuthukise umphumela wokuvuselela indawo yokudlulisa ubuningi bezinto, futhi uthuthukise ukusebenza kahle kwe-devolatilization. ;kodwa-ke, isivinini esikhulu ngokweqile senza izinto ezibonakalayo Isikhathi sokuhlala esigabeni se-devolatilization sincishiswa kakhulu, futhi ukusebenza kahle kwe-devolatilization kuncipha kunalokho.

2. Isivinini esikhulu sesikulufu, inani lokuphakelayo kanye nezinga lokushisa lesethi yomphongolo yizici eziyinhloko ezithonya inqubo yokuqeda amandla ku-twin-screw extruder.Lezi zici zingathinta izinga lokushisa lezinto ezibonakalayo, ukugcwala kwe-groove, isikhathi sokuhlala kanye nobude obugcwele obusebenzayo, ngaleyo ndlela kuthinte i-devolatilization ngezindlela eziningi.Ngenqubo ethile, kunephuzu lokusebenza eliphelele, futhi esimweni sokusebenza okuzinzile, ukusebenza kahle okuphezulu kakhulu kwe-devolatilization kungatholakala.

I-3, ukuncishiswa okufanele kokuphakelayo kunganciphisa izinga lokugcwalisa lesigaba sokukhipha umoya, ukuze ukusebenza kahle kwe-devolatilization kuthuthukiswe;kodwa umthamo wokuphakelayo ophansi kakhulu awugcini nje ukunciphisa inani le-extrusion kanye nokuguquguquka, kodwa futhi ngenxa yokuthi izinga lokugcwalisa liphansi kakhulu, akwanele ukwakha ukuncibilika I-pool inciphisa ukusebenza kahle kwe-foaming kanye ne-devolatilization, ngakho-ke inani lokuphakelayo kufanele libe ngokulinganisela.

4. Ukwandisa isikhathi sokuhlala sezinto ezisesigabeni se-devolatilization nokwandisa ubude besigaba se-devolatilization kungathuthukisa ukusebenza kahle kwe-devolatilization.Ngenxa yalesi sizathu, kubhekwa njengokwandisa ubude besigaba sokukhipha umoya futhi kusetshenziswe i-multi-stage exhaust kumklamo wesakhiwo sesikulufa.
