Ipayipi le-PVC, ibhodi kanye neshidi konke kusebenza emgqonyeni wesikulufu esiphindwe kabili, kodwa okwesokudla uyahluka ngephrofayela yesikulufu, okukhiphayo futhi - ngaphezu kwakho konke - ukuvikela ukugqokwa. Ipayipi ithanda ukuphuma okuzinzile nokucindezela; ibhodi legwebu kanye neshidi kugijima isigcwalisi esiphezulu futhi kudinga ukumelana nokuhuzuka okuqinile. Thola usayizi ukuze ufane ne-extruder yakho, bese ukhetha i-nitrided noma i-bimetallic ngokusekelwe ekutheni ifomula yakho iphethe isigcwalisi esingakanani.

I-conical twin screw extruder ingumshini wokukhipha ogxile ku-PVC onezikulufu ezimbili ezicijile, ezihlanganayo - ububanzi ekugcineni kokuphakelayo, emincane ekugcineni. Ijiyomethri ewukhonkolo inikeza i-torque ephezulu kanye nokucindezelwa okuqinile ngobude obuhlangene, okwenza kube umshini ojwayelekile wepayipi le-PVC, iphrofayili, ibhodi kanye nokukhiqizwa kwe-WPC.

Umphongolo we-screw we-twin oyindilinga iyingxenye ye-extrusion ecijile, ene-twin-bore lapho izikulufu ezimbili ezikhonkolo zizungeza ngaphakathi kombhobho oyikhonikhi ofanayo. I-geometry ene-tapered iletha ukuphakela okuqinile nokucindezelwa okuphezulu ngobude obufushane, yingakho isikulufu se-conical twin kanye nomgqomo kuyisinqumo esijwayelekile sepayipi le-PVC, iphrofayili, ishidi kanye ne-WPC extrusion.

Umgqomo wesikulufa wokubumba umjovo ogugile uyakuxwayisa ngaphambi kokuthi wehluleke. Buka izimpawu ezinhlanu: isisindo sokudubula esikhukhulekayo, amachashaza amnyama abuya ngemva kokuhlanza, ukukhuphuka komthwalo wemoto endaweni efanayo okukhiphayo, i-splay noma ukonakala kwendawo, kanye nokululama kancane kwezikulufu. Enye yalezi ingaba nezinye izimbangela; okubili noma okuthathu ndawonye, ​​kuthrenda ngendlela engafanele emavikini amaningi, khomba ngokulinganayo kusikulufa esigugile kanye nomgqomo. Qinisekisa nge-caliper ngaphambi kokufaka esikhundleni.

I-screw barrel iwumgogodla womshini wakho wokubumba umjovo. Incibilikisa ipulasitiki yakho, iyixube, futhi iyiphushele esikhunjeni - umjikelezo emva komjikelezo, iminyaka. Uma ingalungile ngohlelo lwakho lokusebenza, uyibona yonke indawo: isisindo sokudubula esingahambisani, ukonakala kwendawo, amachashaza amnyama, namazinga akhuphukayo. Lo mhlahlandlela uhlanganisa zonke izinqumo ukuze ukwazi ukukulungisa okokuqala.

Isilinganiso sokujova isikulufu se-L/D siwubude bokusebenza obuhlukaniswa ngedayamitha yesikulufu, futhi izikulufu eziningi zokujova zisebenza ngo-18:1 ukuya ku-25:1. Nakhu okungekho ishidi elithile elikutshela kona: awukwazi ukushintsha i-L/D emshinini osuvele ungumnikazi wawo. Ubude bulungiswa umgqomo. Ongakwazi ukukushintsha i-screw diameter, futhi emgqonyeni ogxilile lapho ukukhetha okukodwa kuhambisa i-L/D, umthamo wokudubula, nokucindezela komjovo ndawonye, ​​ezindaweni eziphambene. Isikulufu esincane sinikeza i-L/D ephakeme, ishothi encane, nokucindezela okwengeziwe. Qondanisa lokho kuhweba ne-resin yakho nengxenye yakho, futhi imibuzo eminingi ye-L/D iziphendula yona.
