Isikulufu Esisodwa Esimelana Ne-Super Wear

Isikulufa Ububanzi

Ukucaciswa okujwayelekile kufaka phakathi u-35mm, 45mm, 65mm, 75mm, 85mm, 90mm, njll. Isibonelo, lapho ucubungula amapayipi e-PVC, isikulufu esingu-65mm sisetshenziswa kabanzi njengoba sifinyelela ibhalansi enhle phakathi kokukhiphayo nokusetshenziswa kwamandla.

I-Length-to-Diameter Ratio (Isilinganiso se-L/D)

Ngokujwayelekile isukela ku-20:1 kuye ku-30:1. Kumapulasitiki azwela ukushisa njenge-PVC, isilinganiso se-L/D ngokuvamile siphakathi kuka-20:1 no-25:1. Lokhu kuqinisekisa i-plasticization eyanele ngenkathi kunciphisa isikhathi sokuhlala sezinto ezibonakalayo emgqonyeni ukuze kuncishiswe ingozi yokubola.

Isilinganiso sokucindezela

Ngokuvamile iwela phakathi kuka-3.5:1 no-4.5:1. Isilinganiso esikhudlwana sokucindezelwa sisiza ukwenziwa kwepulasitiki okugcwele kanye nokuhlangana kwezinto ze-PVC.

Ukujula Kwesiteshi

The screw channel is relatively shallow, especially in the metering section. This design reduces the residence time of materials and minimizes the possibility of decomposition.

Inombolo Yezindawo Zokushisisa Nezokupholisa

Iyahlukahluka ngokusekelwe kububanzi besikulufa kanye nezicaciso zemishini, ngokuvamile isukela ezindaweni ezingu-5 kuye kwezingu-6. Isibonelo, i-extruder enesikulufu esisodwa esinobubanzi obuyizikulufu esingu-65mm singase sibe nezindawo zokushisisa nezokupholisa ezingu-6 ukuze sikwazi ukulawula izinga lokushisa okunembile engxenyeni ngayinye.

Isivinini seScrew

Ibanga lesivinini lidinga ukulungiswa ngokuya ngobubanzi obuthile besikulufa kanye nezidingo zokukhiqiza. Ngesikulufu esingu-φ65mm, lapho ukhiqiza amapayipi anogqinsi lwedonga elingu-3mm, isivinini esinconywayo silawulwa ngaphakathi kwebanga elingu-25-35rpm.

Drive Power

Kuhlobene nobubanzi besikulufu nokuphumayo. Isibonelo, i-extruder yesikulufu esisodwa esinobubanzi besikulufa esingu-65mm ngokuvamile sinamandla okushayela angu-45-90kw.

Izinga Lokushisa Lokusebenza

Izinga lokushisa lesigaba sokuphakela livamise ukuba ngu-160-170℃, ingxenye encibilikayo ingu-180-190℃, kanti ingxenye yekhanda lokufa ingu-175-185℃.
