A i-extruder yesikrufu esijijekileyo esiphindwe kabiniluhlobo lwe-twin screw extruder enezikrufu ezimbini ezicwangciswe ngendlela ye-conical, ezinciphayo ukuya ekupheleni kokukhupha kwe-extruder. Olu yilo lubonelela ngokunciphisa kancinci umthamo wetshaneli ye-screw, okubangela uxinzelelo olongezelelekileyo kunye nokuphucula ukuhlanganiswa. I-conical twin screw extruder yenziwe ikakhulu yi-barrel screw, inkqubo yokudlulisa iigiya, ukutya okunomlinganiselo, i-vacuum exhaust, ukufudumeza, ukupholisa kunye nezixhobo zokulawula umbane.
I-extruder ye-conical twin screw ifanelekile ukuvelisa iimveliso ze-PVC ngomgubo oxutyiweyo. I-PVC yi-polymer ye-thermoplastic enezicelo ezininzi kumashishini ahlukeneyo, njengokwakha, ukupakisha, umbane, iimoto, kunye nezonyango. Nangona kunjalo, i-PVC ayihambelani nezinye ii-polymers ezininzi kunye nezongezo, kwaye ifuna iindlela ezikhethekileyo zokucubungula ukuze kufezekiswe iipropati kunye nokusebenza okufunekayo. I-extruder ye-conical twin screw inokubonelela ngokuxuba, ukunyibilikisa, ukuchithwa, kunye nokudibanisa i-PVC kunye nezongezo zayo ngendlela eqhubekayo nefanelekileyo.
I-extruder ye-conical twin screw ikwayizixhobo ezikhethekileyo ze-WPC powder extrusion. I-WPC imele i-wood-plastic composite, eyimpahla edibanisa imicu yomthi okanye umgubo womthi kunye nee-polymers ze-thermoplastic, ezifana ne-PVC, i-PE, i-PP, okanye i-PLA. I-WPC ineenzuzo zombini zomthi kunye neplastiki, ezinje ngamandla aphezulu, ukuqina, ukumelana nemozulu, kunye nokuphindeka kwakhona. I-conical twin screw extruder inokucubungula i-WPC powder ngokukhupha okuphezulu, ukusebenza okuzinzileyo, kunye nobomi benkonzo ende.
Ngezixhobo ezahlukeneyo zokubumba kunye nezixhobo ezisezantsi, i-extruder ye-conical twin screw extruder inokuvelisa iimveliso ezahlukeneyo ze-PVC kunye ne-WPC, ezifana neepayipi, iisilingi, iiprofayili zeefestile, ishidi, i-decking, kunye nee-granules. Ezi mveliso zinemilo eyahlukeneyo, ubukhulu, kunye nemisebenzi, kwaye zinokuhlangabezana neemfuno ezahlukeneyo zabathengi kunye neemarike.
Inkcazo yeNkqubo
Inkqubo yokukhupha izikrufu ezimbini ezijijekileyo inokwahlulwa ibe ngamanqanaba amane aphambili: ukondla, ukunyibilikisa, ukudiliza, kunye nokubumba.
Ukondla
Inqanaba lokuqala lokukhupha izikrufu ezimbini ezijijekileyo kukutya. Kweli nqanaba, izinto ezikrwada, ezifana nomgubo wePVC okanye weWPC, kunye nezinye izongezo, ezifana neziqinisi, izinto zokuthambisa, izihluzi, izihluzi, iipigment, kunye nezilungisi, zilinganiswa kwaye zondliwa kwi-extruder zizixhobo ezahlukeneyo zokuthambisa, ezifana nee-screw augers, iitreyi zokungcangcazela, iibhanti zokulinganisa, kunye neempompo zokujova. Izinga lokutya kunye nokuchaneka zizinto ezibalulekileyo ezichaphazela umgangatho kunye nokungaguquguquki kweemveliso zokugqibela. Izinto ezikrwada zinokuxutywa kwangaphambili kwaye zondliwa, okanye zohlulwe ngokwahlukeneyo kwaye zilinganiswe ngokulandelelana kwi-extruder, kuxhomekeke kwifomyula kunye neempawu ezifunwayo zeemveliso.
Ukunyibilika
Inqanaba lesibini le-conical twin screw extrusion liyanyibilika. Kweli nqanaba, izinto ezikrwada ziyathuthwa, zicinezelwe, kwaye zifudunyezwe zizikrufu ezijikelezayo kunye nezifudumezi zeebhareli, kwaye ziguqulwe ukusuka kwimeko eqinileyo ukuya kwimeko yolwelo. Inkqubo yokunyibilika ibandakanya zombini igalelo lamandla obushushu kunye noomatshini, kwaye ichaphazeleka sisantya sesikrufu, ukwakheka kwesikrufu, ubushushu bebhareli, kunye neempawu zezinto. Inkqubo yokunyibilika ikwabalulekile ekusasazekeni nasekusasazweni kwezinto ezongeziweyo kwi-polymer matrix, kunye nokuqaliswa kweempendulo zeekhemikhali, ezifana nokudibanisa, ukufakelwa, okanye ukubola, okunokwenzeka kwi-melt. Inkqubo yokunyibilika kufuneka ilawulwe ngononophelo ukuze kuthintelwe ukugqithisa, ukucheba kakhulu, okanye ukunyibilika ngaphantsi kwezinto, okunokubangela umgangatho kunye nokusebenza kakubi kwemveliso.
Ukuchithwa kwe-Devolatilization
Inqanaba lesithathu lokukhutshelwa kweesikrufu ezimbini ezijijekileyo kukukhutshelwa kweesikrufu. Kweli nqanaba, izinto eziguquguqukayo, ezinje ngomswakama, umoya, ii-monomers, izinyibilikisi, kunye neemveliso zokubola, zisuswa kwi-melt ngokufaka i-vacuum kwiindawo zokungenisa umoya ecaleni kwebharele ye-extruder. Inkqubo yokukhutshelwa kweesikrufu ibalulekile ekuphuculeni umgangatho wemveliso kunye nozinzo, kunye nokunciphisa impembelelo yokusingqongileyo kunye neengozi zempilo zenkqubo yokukhutshelwa kweesikrufu. Inkqubo yokukhutshelwa kweesikrufu ixhomekeke kuyilo lwezikrufu, inqanaba le-vacuum, i-melt viscosity, kunye neempawu zezinto. Inkqubo yokukhutshelwa kweesikrufu kufuneka iphuculwe ukuze kufumaneke ukususwa okwaneleyo kwee-volatiles ngaphandle kokubangela ukugqwala kakhulu, ukukhukula kwe-vent, okanye ukubola kwe-melt.
Ukubumba
Inqanaba lesine nelokugqibela lokukhupha izikrufu ezimbini ezijijekileyo liyabumba. Kweli nqanaba, ukunyibilika kukhutshwa ngedayi okanye isikhunta esimisela imo kunye nobukhulu bemveliso. Idayi okanye isikhunta sinokuyilwa ukuvelisa iimveliso ezahlukeneyo, ezinje ngemibhobho, iiprofayili, ishiti, ifilimu, okanye iigranules. Inkqubo yokubumba iphenjelelwa yijiyometri yedayi, uxinzelelo lwedayi, ubushushu bedayi, kunye ne-rheology yokunyibilika. Inkqubo yokubumba kufuneka ilungiswe ukuze kufezekiswe ii-extrudates ezifanayo nezigudileyo ngaphandle kweziphene, ezinje ngokudumba kwedayi, ukwaphuka kwedayi, okanye ukungazinzi kobukhulu. Emva kwenkqubo yokubumba, ii-extrudates ziyapholiswa, zinqunyulwe, kwaye ziqokelelwe zizixhobo ezisezantsi, ezinje ngee-calibrators, ii-haul-offs, ii-cutters, kunye nee-winders.
