Kugereranya ibice bimwe-byombi hamwe na twin-screw extruders

(1) Intangiriro yaumugozi umwe

Extruders imwe imwe, nkuko izina ribigaragaza, ifite umugozi umwe imbere muri barri ya extruder. Mubisanzwe, uburebure bukora bugabanijwemo ibice bitatu, kandi uburebure bukomeye bwibice bitatu bugenwa ukurikije diameter ya screw, ikibanza, hamwe nubujyakuzimu, kandi muri rusange bigabanijwe ukurikije buri kimwe cya gatatu.

Igice cya mbere: guhera kumurongo wanyuma wicyambu cyo kugaburira, byitwa igice cyo gutanga. Ibikoresho hano ntibisabwa guhindurwa plastike, ariko bigomba gushyuha no gukanda. Mubihe byashize, igitekerezo cya kera cyo gukuramo cyizeraga ko ibikoresho hano ari umubiri udafunguye. Nyuma, byaragaragaye ko ibikoresho hano mubyukuri ari plug ikomeye, bivuze ko ibikoresho hano byanyunyujwe. Inyuma ni ikomeye nk'icomeka, igihe cyose irangije imirimo yo gutanga, ni imikorere yayo.

(2) Gukoresha extruder imwe imwe

Extruder imwe imwe ikoreshwa cyane mugukuramo imiyoboro, impapuro, amasahani, hamwe nibikoresho byanditse, hamwe no guhunika ibikoresho bimwe byahinduwe.

(1) Intangiriro yatwin-screw extruder

Twin-screw extruder ikubiyemo sisitemu zikurikira. Sisitemu ya screw irangiza cyane cyane plastike no gutanga ibintu, bigira uruhare runini mumikorere nubwiza bwibicuruzwa byarangiye.

System Kugaburira sisitemu: harimo hopper, moteri ikurura, na moteri yo kugaburira. Irashobora gukumira kwirundanyiriza ibintu no koroshya kwinjira neza ku cyambu.

System Sisitemu yo gushyushya hanze: Koresha cyane cyane inkoni yo gushyushya na silinderi kugirango ushushe ibikoresho neza kandi uteze imbere plastike.

System Sisitemu yo gukonjesha: Sisitemu yo guhanahana ubushyuhe igizwe namavuta yohereza ubushyuhe cyangwa amazi bikoreshwa mukugabanya ubushyuhe bwa fuselage, kugirango bigenzure neza ubushyuhe bwa silinderi.

Sisitemu ya Hydraulic ihindura sisitemu: Koresha ecran ya filteri isimburwa kugirango wirinde umwanda, utezimbere urwego rwa plastike, kandi urebe ko uburinganire n'ubwuzuzanye bwibintu bisohoka.

Urugero rwo gusaba rwa twin-screw extruder: ibirahuri bya fibre byashimangiwe, granulaire ya flame (nka PA6, PA66, PET, PBT, PP, PC ikomeza flame retardant, nibindi), granulation yuzuye (nka PE, PP yuzuyemo 75% CaCO3), granulation yibikoresho byubushyuhe . granulation material (Nkibikoresho byibyatsi, ibikoresho byerekana), XLPE imiyoboro yamashanyarazi (nka masterbatch yo guhuza amazi ashyushye guhuza), kuvanga plastike ya termosetting no kuvoma (nka fenolike resin, epoxy resin, ifu yifu), ibishishwa bishyushye, PU ikora gukuramo granulation (nka EVA ishyushye gushonga, polyurethane), K resin, granulation ya SBS devolatilisation, nibindi.

Ingero zikoreshwa za screw imwe ya extruder:ibereye imiyoboro ya PP-R, imiyoboro ya gaze ya PE, imiyoboro ya PEX ihuza imiyoboro, imiyoboro ya aluminium-plastike, imiyoboro ya ABS, imiyoboro ya PVC, imiyoboro ya silicon ya HDPE hamwe n’imiyoboro inyuranye ihuriweho hamwe; bikwiranye na PVC, PET, PS, PP, PC hamwe nandi mashusho hamwe namasahani, nibindi plastiki nka filaments, inkoni, nibindi.; Guhindura umuvuduko wa extruder no guhindura imiterere ya screw yo gukuramo irashobora gukoreshwa mubikorwa bya PVC na polyolefine. N'indi myirondoro ya plastike.
