A conical twin dunƙule extruderwani nau'in tagwayen dunƙule fiɗa ne wanda ke da sukurori guda biyu da aka jera su a siffa mai maɗaukaki, suna tafe zuwa ƙarshen fitarwar. Wannan ƙira yana ba da raguwa a hankali a cikin ƙarar tashar screw, yana haifar da ƙara yawan matsa lamba da haɓaka haɓakawa. A conical tagwaye dunƙule extruder ne yafi hada da dunƙule ganga, gear watsa tsarin, adadi mai yawa ciyar, injin shaye, dumama, sanyaya da kuma lantarki sarrafa kayayyakin.
A conical twin dunƙule extruder ya dace da samar da PVC kayayyakin daga gauraye foda. PVC polymer thermoplastic ne wanda ke da nau'ikan aikace-aikace a masana'antu daban-daban, kamar gini, marufi, lantarki, motoci, da likitanci. Duk da haka, PVC ba ta dace da yawancin polymers da additives ba, kuma yana buƙatar dabarun sarrafawa na musamman don cimma kaddarorin da ake so da aiki. A conical tagwaye dunƙule extruder iya samar da zama dole hadawa, narkewa, devolatilization, da kuma homogenization na PVC da Additives a ci gaba da ingantaccen hanya.
A conical tagwaye dunƙule extruder kuma na musamman kayan aiki ga WPC foda extrusion. WPC tana nufin itace-roba composite, wanda shine kayan da ke haɗa zaruruwan itace ko gari na itace tare da polymers na thermoplastic, kamar PVC, PE, PP, ko PLA. WPC yana da fa'idodin itace da filastik, kamar ƙarfi mai ƙarfi, karko, juriyar yanayi, da sake yin amfani da su. A conical twin dunƙule extruder iya aiwatar da WPC foda tare da babban fitarwa, barga Gudun, da kuma dogon sabis rayuwa.
Tare da kayan aiki daban-daban da ƙasa mai ƙasa, wata hanya tagwayen tagwaye na conal, kamar bututu, bayanan bayanan, bene, da granules. Waɗannan samfuran suna da siffofi daban-daban, girma, da ayyuka, kuma suna iya biyan buƙatun abokan ciniki da kasuwanni daban-daban.
Bayanin Tsari
Za'a iya raba tsarin tagwayen dunƙule dunƙule extrusion zuwa manyan matakai guda huɗu: ciyarwa, narkewa, sadaukarwa, da siffatawa.
Ciyarwa
Matakin farko na conical twin dunƙule extrusion shine ciyarwa. A cikin wannan mataki, ana amfani da albarkatun kasa, irin su PVC ko WPC foda, da sauran abubuwan da suka hada da, irin su stabilizers, lubricants, fillers, pigments, da modifiers, ana metered da kuma ciyar da su a cikin extruder ta daban-daban ciyar da na'urorin, irin su dunƙule augers, vibratory. trays, bel masu auna, da famfunan allura. Adadin ciyarwa da daidaito sune mahimman abubuwan da ke shafar inganci da daidaiton samfuran ƙarshe. Za a iya haɗa albarkatun ƙasa kafin a haɗa su kuma a ciyar da su, ko kuma dabam kuma a bi da su a cikin mai fitarwa, dangane da ƙira da abubuwan da ake so na samfuran.
Narkewa
Mataki na biyu na conical twin dunƙule extrusion yana narkewa. A wannan mataki, ana isar da albarkatun ƙasa, matsawa, da dumama ta screws masu juyawa da na'urorin dumama ganga, kuma ana canza su daga ƙaƙƙarfan yanayi zuwa yanayin ruwa. Tsarin narkewa ya haɗa da shigarwar makamashin thermal da injina, kuma saurin dunƙulewa, daidaitawar dunƙule, zafin ganga, da kaddarorin kayan yana tasiri. Hakanan tsarin narkewa yana da mahimmanci don tarwatsawa da rarraba abubuwan da ke cikin matrix polymer, da kuma ƙaddamar da halayen sinadarai, kamar haɗin giciye, grafting, ko lalata, wanda zai iya faruwa a cikin narke. Dole ne a kula da tsarin narkewa a hankali don kauce wa zafi mai yawa, fiye da raguwa, ko narkewar kayan aiki, wanda zai iya haifar da rashin ingancin samfurin da aiki.
Devolatilization
Mataki na uku na conical twin dunƙule extrusion extrusion ne devolatilization. A cikin wannan mataki, ana cire abubuwan da ba su da ƙarfi, kamar danshi, iska, monomers, kaushi, da samfuran bazuwar, daga narkewar ta hanyar yin amfani da vacuum a tashar jiragen ruwa tare da ganga mai extruder. Tsarin keɓancewa yana da mahimmanci don haɓaka ingancin samfur da kwanciyar hankali, da kuma rage tasirin muhalli da haɗarin kiwon lafiya na tsarin extrusion. Tsarin keɓewa ya dogara da ƙirar dunƙule, matakin injin, narkewar danko, da halayen kayan aiki. Dole ne a inganta tsarin keɓewa don cimma isasshiyar kawar da sauye-sauye ba tare da haifar da kumfa mai yawa ba, ambaliya, ko narkewar lalacewa.
Siffata
Mataki na huɗu kuma na ƙarshe na conical twin dunƙule extrusion yana siffata. A cikin wannan mataki, ana fitar da narke ta hanyar mutuwa ko wani nau'i wanda ke ƙayyade siffar da girman samfurin. Za a iya ƙirƙira mutu ko ƙirƙira don samar da samfura daban-daban, kamar bututu, bayanan martaba, takarda, fim, ko granules. Tsarin siffatawa yana tasiri ta hanyar lissafi mai mutu, mutun matsa lamba, mutun zafin jiki, da narke rheology. Dole ne a daidaita tsarin siffa don cimma daidaito da santsi ba tare da lahani ba, kamar su kumbura, narkewar karaya, ko rashin kwanciyar hankali. Bayan aiwatar da tsari, ana sanyaya abubuwan da aka fitar da su, a yanka su, kuma ana tattara su ta kayan aikin ƙasa, kamar su calibrators, masu ɗaukar kaya, masu yankewa, da iska.
Kammalawa
A conical twin dunƙule extruder ne m da ingantaccen na'urar don samar da PVC da WPC kayayyakin daga gauraye foda. Zai iya samar da ayyukan da ake buƙata na ciyarwa, narkewa, ƙaddamarwa, da kuma tsarawa a cikin ci gaba da sarrafawa. Hakanan yana iya samar da samfura daban-daban tare da siffofi daban-daban, girma, da ayyuka daban-daban, ta amfani da nau'i daban-daban da kayan aiki na ƙasa. A conical twin dunƙule extruder yana da abũbuwan amfãni daga mai kyau compounding, babban fitarwa, barga Gudun, da kuma dogon sabis rayuwa, kuma zai iya saduwa da bambancin bukatun abokan ciniki da kasuwanni.
