Ngihlala ngibheka ukuhambisana kwe-extruder nezithasiselo engizisebenzisayo. I ukukhetha uhlobo extruder kunomthelela ekuhlanganiseni, i-plasticization, kanye nokusatshalaliswa kwezithasiselo. Lezi zici zibalulekile ekusebenzeni nasekuzinzeni kwe-additive masterbatch. Ngilungisa izinga lokushisa, isivinini sesikulufa, nokucindezela emuva ukuze kuzuzwe imiphumela emihle. Ama-twin-screw extruder athuthukisa ukuxuba nokwenza ipulasitiki, ukuqinisekisa ukuhlakazeka okungcono kwezithasiselo kanye nokwenza ngcono ikhwalithi isiyonke ye-additive masterbatch.
- Ukuzinza kwekhwalithi kuncike ekufaneni kokuhlakazeka kanye nokuvumelana kosayizi wezinhlayiyana.
- Izinga lokuthobela ukusebenza kufanele lihlangabezane namazinga omkhakha.
- Ukusebenza kahle kokukhiqiza kuyathuthuka nge-extruder efanele nezilungiselelo zenqubo.
Isikali Sokukhiqiza
Iqoqo elincane
Ngokukhiqizwa kwenqwaba encane noma ukuhlolwa okuvamile, Ngisebenzisa ilabhorethri noma ama-micro extruder. Le mishini isebenza phakathi 0.25 kg/h futhi 150 kg/h. Ama-Micro Extruder angisize nginciphise ukumosha, ikakhulukazi uma usebenza ngezithasiselo ezibizayo noma ama-polymers akhethekile. Imishini yesikali sokuhlola ilungele ukukhiqizwa kwesampula kanye nezivivinyo zangaphambi kokuthengisa.
Isikali Esikhulu
Lapho ngikhuphuka, Ngigxile izidingo zokukhiphayo, izici ezibonakalayo, kanye nezidingo zokucubungula. Ama-extruder angama-twin screw aphatha kahle ukukhiqizwa kwe-masterbatch enkulu okungezayo. Ngifanisa ne amandla athile emishini (I-SME) okokufaka ukuqinisekisa ikhwalithi yomkhiqizo engaguquki.
Ipharamitha eyinhloko esetshenziselwa ukukhuphula ama-TSE amandla athile emishini (I-SME) okokufaka kwenqubo. I-SME ihlinzeka ngamandla ngeyunithi ngayinye yesisindo edluliswa isuka ku-extruder drive motor ngokusebenzisa izikulufu futhi iwafake kwinhlanganisela ecutshungulwayo.. I-SME ingaphinde ibe nomthelela ezinhlelweni zomkhiqizo wokugcina, ngakho ukufanisa ama-SME nakho kungasiza ekuqinisekiseni ikhwalithi yomkhiqizo.
Izakhiwo ezifiselekayo
Ukungaguquguquki Kombala
Ngithembele kuzithasiselo ukuze ngizuze umbala ongaguquki emikhiqizweni yepulasitiki. Ukuhlakazwa kwe-pigment efanele kuvimbela ukuhlukahluka komthunzi futhi kuthuthukisa ukukhanga okubonakalayo. I-Twin-screw extruder inginika ukulawula engikudingayo kumbala ofanayo ku-masterbatch engeziwe.
Izakhiwo Zemishini
Izigcwalisi ezifana ne-calcium carbonate ziguqula izakhiwo zemishini ezinjengokuqina namandla. Ngikhetha i-extruder ebhalansisa ukusebenza nezindleko kuyilapho ngigcina izici zokucubungula ezinhle kakhulu ku-additive masterbatch.
Amazinga Ekhwalithi
Ngihlale ngibeka izidingo zekhwalithi ngaphambi kokukhetha okokusebenza. Ukunemba ekuphakeleni, ukuxuba, futhi i-pelletizing iqinisekisa ukuthi ngihlangabezana namazinga omkhakha we-additive masterbatch kanye ne-filler masterbatch. Ngigwema amaphutha avamile ngokulawula ngokucophelela izinga lokushisa lesigaba sokudla, plasticizing kanye okushisa homogenizing, kanye nezinga lokudla.

| Isu Lomugqa Wokukhiqiza | Iqinisekisa ukuthi izingxenye zisebenza ndawonye ngempumelelo, ukuvimbela amabhodlela kanye nokwandisa ukusebenza kwesistimu. |
Ithiphu: Ngihlale ngilinganisela ukutshalwa kwezimali kwezimali nokusebenza kahle. Ngenza isiqiniseko sokuthi zonke izingxenye zomugqa wokukhiqiza zisebenza ndawonye ukuze kuvinjelwe amabhodlela futhi kwandise ukusebenza.
Ngibona umehluko ocacile phakathi kwezinhlobo ze-extruder ezilolonga yonke iphrojekthi ye-masterbatch. Ukukhetha kwami kuncike ezicini zefiber, izidingo zomthamo, kanye namazinga emvelo. Nasi isithenjwa esisheshayo:
| Ukucatshangelwa Okubalulekile | Incazelo |
|---|---|
| I-Fiber Characteristic Matching | Imicu emide idinga okokusebenza okuphezulu kokuhlakaza i-shear, kuyilapho imicu emifushane idinga ukugunda okuncishisiwe ukuze kuncishiswe ukuphuka. |
| Isidingo Samandla | Imigqa yokuhlola emincane (5-50kg/h) sebenzisa ama-twin screw extruders, ngenkathi imigqa yezimboni (500-2000kg/h) zidinga ama-extruder ama-twin-screw amakhulu. |
| Izidingo Zemvelo | Izinto zokusebenza kufanele zihambisane nokwelashwa kwamanzi angcolile kanye namazinga okukhishwa kwe-VOC. |
- Ngihlale ngibheka amazinga wokuzenzakalela ukuze ngilawule izindleko zabasebenzi kanye nokuvumelana kokukhiqiza.
- Ngibeka phambili ukonga kukagesi ekongeni isikhathi eside.
Ngincoma ukuthi uhlole ubuchwepheshe obusha noma uxhumane nochwepheshe ngaphambi kokwenza isinqumo esingujuqu.
