A i-conical twin screw extruderluhlobo lwe-twin screw extruder enezikrufu ezibini ezicwangciswe ngokwemilo econical, ecothayo ukuya kwisiphelo sokukhuphela se-extruder. Olu luyilo lubonelela ngokucutha kancinci kumthamo wesijija se-screw, okukhokelela ekunyukeni koxinzelelo kunye nokuphuculwa kokudibanisa. I-conical twin screw extruder yenziwa ikakhulu sisikrufu sombhobho, inkqubo yothumelo lwegiya, ukondla ngokobungakanani, umbhobho wokukhupha, ukufudumeza, ukupholisa kunye nezinto zokulawula umbane.
I-conical twin screw extruder ifanelekile ukuvelisa iimveliso zePVC kumgubo oxutywe. I-PVC yipolymer ye-thermoplastic enoluhlu olubanzi lwezicelo kumashishini ahlukeneyo, afana nokwakha, ukupakishwa, umbane, iimoto, kunye nezonyango. Nangona kunjalo, i-PVC ayihambelani nezinye iipolymers ezininzi kunye nezongezo, kwaye ifuna ubuchule obukhethekileyo bokucwangcisa ukufezekisa iipropati ezifunwayo kunye nokusebenza. I-conical twin screw extruder inokubonelela ngokuxuba okuyimfuneko, ukunyibilika, ukuchithwa, kunye ne-homogenization ye-PVC kunye nezongezo zayo ngendlela eqhubekayo nefanelekileyo.
I-conical twin screw extruder ikwasisixhobo esikhethekileyo se-WPC powder extrusion. I-WPC imele i-wood-plastic composite, into edibanisa iintsinga zomthi okanye umgubo womthi kunye neepolima ze-thermoplastic, ezifana ne-PVC, i-PE, i-PP, okanye i-PLA. I-WPC ineengenelo zazo zombini iinkuni kunye neplastiki, njengokuqina okuphezulu, ukuqina, ukumelana nemozulu, kunye nokuphinda kusetyenziswe. I-conical twin screw extruder inokwenza i-WPC powder enemveliso ephezulu, ukubaleka okuzinzileyo, kunye nobomi benkonzo ende.
Ngezixhobo ezahlukeneyo zokubumba kunye nezantsi, i-conical twin screw extruder inokuvelisa iimveliso ezahlukeneyo ze-PVC kunye ne-WPC, njengemibhobho, iisilingi, iiprofayili zefestile, i-sheet, i-decking, kunye ne-granules. Ezi mveliso zinemilo eyahlukeneyo, ubungakanani, kunye nemisebenzi, kwaye zinokuhlangabezana neemfuno ezahlukeneyo zabathengi kunye neemarike.
Inkcazo yeNkqubo
Inkqubo ye-conical twin screw extrusion inokwahlulwa ibe ngamanqanaba amane aphambili: ukutyisa, ukunyibilika, ukutshabalalisa, kunye nokubunjwa.
Ukutya
Inqanaba lokuqala le-conical twin screw extrusion kukutya. Kweli nqanaba, izixhobo eziluhlaza, ezifana ne-PVC okanye i-WPC yomgubo, kunye nezinye izongezo, ezinje ngezizinzi, izithambisi, izihluzi, ii-pigments, kunye nezilungisi, zibalwa kwaye zondliwa kwi-extruder ngezixhobo ezahlukeneyo zokutyisa, ezinjenge-screw augers, vibratory. iitreyi, iibhanti zokulinganisa ubunzima, neempompo zenaliti. Izinga lokutya kunye nokuchaneka zizinto ezibalulekileyo ezichaphazela umgangatho kunye nokuhambelana kweemveliso zokugqibela. Izinto eziluhlaza zinokuxutywa kwangaphambili kwaye zondliwe, okanye ngokwahlukileyo kwaye zilinganiswe ngokulandelelana kwi-extruder, kuxhomekeke ekuqulunqweni kunye neempawu ezifunwayo zeemveliso.
Ukunyibilika
Inqanaba lesibini le-conical twin screw extrusion liyanyibilika. Kweli nqanaba, izinto eziluhlaza zihanjiswa, zixinzelelwe, kwaye zifudunyezwe zizikrufu ezijikelezayo kunye nezifudumezi ze-barrel, kwaye zitshintshwe ukusuka kwisigxina ukuya kwimeko yolwelo. Inkqubo yokunyibilika ibandakanya igalelo lamandla e-thermal kunye noomatshini, kwaye iphenjelelwa sisantya se-screw, ukumiswa kwesikrufu, ubushushu bombhobho, kunye neempawu zezinto eziphathekayo. Inkqubo yokunyibilika ibaluleke kakhulu ekuhlakazeni nasekuhanjisweni kwezongezo kwi-polymer matrix, kunye nokuqaliswa kweempendulo zemichiza, ezifana ne-cross-linking, i-grafting, okanye i-degradation, enokuthi yenzeke kwi-melted. Inkqubo yokunyibilika kufuneka ilawulwe ngononophelo ukuthintela ukutshisa, ukucheba ngokugqithisileyo, okanye ukunyibilika ngaphantsi kwezinto, nto leyo enokubangela umgangatho ophantsi wemveliso kunye nokusebenza.
Ukutshatyalaliswa
Inqanaba lesithathu le-conical twin screw extrusion yi-devolatilization. Kweli nqanaba, izinto eziguquguqukayo, ezinje ngokufuma, umoya, iimonomers, izinyibilikisi, kunye neemveliso zokubola, ziyasuswa kwinyibilika ngokufaka ivacuum kumazibuko okungena ecaleni kombhobho ophumayo. Inkqubo ye-devolatilization ibalulekile ekuphuculeni umgangatho wemveliso kunye nokuzinza, kunye nokunciphisa impembelelo yokusingqongileyo kunye nobungozi bempilo yenkqubo ye-extrusion. Inkqubo ye-devolatilization ixhomekeke kuyilo lwe-screw, inqanaba le-vacuum, i-viscosity enyibilikayo, kunye neempawu eziphathekayo. Inkqubo ye-devolatilization kufuneka iphuculwe ukuze kuphunyezwe ukususwa okwaneleyo kwezinto eziguquguqukayo ngaphandle kokubangela ugwebu olugqithisileyo, ukuphuphuma kwe-vent, okanye ukuncibilika kokunyibilika.
Ukubunjwa
Inqanaba lesine kunye nelokugqibela le-conical twin screw extrusion kukubunjwa. Kweli nqanaba, inyibilika ikhutshelwa ngokufa okanye isikhunta esimisela imilo kunye nobukhulu bemveliso. Idayi okanye ukungunda kunokwenziwa ukuvelisa iimveliso ezahlukeneyo, ezinjengemibhobho, iiprofayili, iphepha, ifilimu, okanye iigranules. Inkqubo yokubumba iphenjelelwa yi-die geometry, uxinzelelo lokufa, ubushushu bokufa, kunye ne-melt rheology. Inkqubo yokubunjwa kufuneka ilungiswe ukuze ifezekise i-extrudates efanayo kunye ne-smooth ngaphandle kweziphene, ezifana nokudumba kwe-fa, i-melt fracture, okanye ukungazinzi kwe-dimensional. Emva kwenkqubo yokubunjwa, ii-extrudates ziyapholiswa, zisikwe, kwaye ziqokelelwe ngezixhobo ezisezantsi, ezifana nezixhobo zokulinganisa, ukuthuthwa, ukusika kunye neewindi.
