A extruder ine makona maviri emakonaimhando ye twin screw extruder ine screw mbiri dzakarongwa muchimiro che conical, dzichidzikira kusvika kumagumo e discharge ye extruder. Dhizaini iyi inoita kuti screw channel volume iderere zvishoma nezvishoma, zvichikonzera kuwedzera kwekumanikidzwa uye kuwedzera kwe compounding. Conical twin screw extruder inonyanya kugadzirwa ne barrel screw, gear transmission system, quantitative feeding, vacuum exhaust, heating, cooling uye electrical control components.
Chinoburitsa screw mbiri dzine conical chakakodzera kugadzira zvigadzirwa zvePVC kubva muupfu hwakasanganiswa. PVC ipolymer yethermoplastic ine mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana, akadai sekuvaka, kurongedza, magetsi, mota, uye ekurapa. Zvisinei, PVC haishande nemamwe mapolymer akawanda nezvimwe zvinowedzera, uye inoda matekiniki akakosha ekugadzirisa kuti iwane hunhu hwaunoda uye mashandiro. Chinoburitsa screw mbiri dzine conical chinogona kupa kusanganisa, kunyungudutsa, kuparadzwa, uye homogenization inodiwa yePVC nezvimwe zvinowedzera nenzira inoenderera mberi uye inoshanda.
Chinoburitsa screw mbiri dzine conical imuchina wakakosha weWPC powder extrusion. WPC inomiririra wood-plastic composite, inova chinhu chinosanganisa mapuranga kana huni huni nema thermoplastic polymers, akadai sePVC, PE, PP, kana PLA. WPC ine zvakanakira zvehuni nepurasitiki, zvakaita sesimba rakasimba, kugara kwenguva refu, kuramba mamiriro ekunze, uye kugona kudzokorodza. Chinoburitsa screw mbiri dzine conical chinogona kugadzirisa huni hweWPC nekushanda kwakasimba, kushanda kwakasimba, uye kushanda kwenguva refu.
Nekushandisa michina yakasiyana-siyana yeforoma neyepasi, chinhu chinoburitsa screw mbiri chine conical chinogona kugadzira zvigadzirwa zvakasiyana-siyana zvePVC neWPC, zvakaita semapaipi, matenga, maprofile emahwindo, jira, decking, uye granules. Zvigadzirwa izvi zvine maumbirwo akasiyana, saizi, uye mabasa, uye zvinogona kusangana nezvinodiwa zvakasiyana-siyana zvevatengi nemisika.
Tsananguro yeMaitiro
Maitiro ekubvisa screw mbiri dzine conical anogona kukamurwa kuita zvikamu zvina zvikuru: kudyisa, kunyungudutsa, kubvisa ngura, uye kuumba.
Kudyisa
Danho rekutanga rekuwedzera screw mbiri dzemakona ndiro rekupa chikafu. Mudanho rino, zvinhu zvisina kugadzirwa, zvakaita sePVC kana WPC powder, nezvimwe zvinowedzera, zvakaita sezvinodzivirira, mafuta, zvinozadza, pigments, uye zvinogadzirisa, zvinoyerwa uye zvinopinzwa muextruder nemidziyo yakasiyana yekudyisa, senge screw augers, vibratory trays, weight-belts, uye injection pumps. Kuwanda kwekudya uye kururama zvinhu zvakakosha zvinokanganisa kunaka uye kugara kwenguva refu kwezvigadzirwa zvekupedzisira. Zvinhu zvisina kugadzirwa zvinogona kusanganiswa uye kupihwa chikafu, kana kuenzaniswa zvakasiyana uye zvakatevedzana muextruder, zvichienderana nekugadzirwa uye hunhu hwezvigadzirwa.
Kunyunguduka
Danho rechipiri rekubuda kwemakona maviri emakona ari kunyunguduka. Mudanho rino, zvinhu zvakagadziriswa zvinoendeswa, zvinomanikidzwa, uye zvinodziiswa nezvikushi zvinotenderera uye zvinodziya zvemabharero, uye zvinoshandurwa kubva pakuva chakasimba kuenda kumamiriro emvura. Maitiro ekunyunguduka anosanganisira simba rekupisa uye remakanika, uye anokonzerwa nekumhanya kwescrew, configuration yescrew, tembiricha yebharero, uye hunhu hwezvinhu. Maitiro ekunyunguduka akakoshawo pakupararira nekupararira kwezvinowedzera mupolymer matrix, uye kutanga kwemaitiro emakemikari, akadai sekubatanidza, kusanganisa, kana kuora, kunogona kuitika mukunyunguduka. Maitiro ekunyunguduka anofanira kudzorwa nokungwarira kudzivirira kupisa zvakanyanya, kuchekwa zvakanyanya, kana kunyunguduka kwezvinhu, izvo zvinogona kukonzera kusashanda zvakanaka kwechigadzirwa.
Kuparadza
Danho rechitatu rekubvisa screw mbiri dzakaita seconical ndeyekubvisa screw. Mudanho rino, zvinhu zvinoshanduka, zvakaita sehunyoro, mhepo, monomers, solvents, uye zvinoora, zvinobviswa kubva mukunyunguduka nekushandisa vacuum panzvimbo dzinobuda vent pabhare reextruder. Maitiro ekubvisa screw akakosha pakuvandudza mhando uye kugadzikana kwechigadzirwa, pamwe nekuderedza kukanganisa kwezvakatipoteredza uye njodzi dzehutano dzemaitiro ekubvisa screw. Maitiro ekubvisa screw anoenderana nekugadzirwa kwescrew, huwandu hwevacuum, viscosity yekunyunguduka, uye hunhu hwezvinhu. Maitiro ekubvisa screw anofanira kugadziriswa kuti abvise screws zvakakwana pasina kukonzera furo rakawandisa, mafashamo emhepo, kana kuora kwemhepo.
Kuumba
Danho rechina uye rekupedzisira re conical twin screw extrusion riri kuumbwa. Mudanho rino, kunyunguduka kunoburitswa kuburikidza nedhayi kana mold iyo inosarudza chimiro nehukuru hwechigadzirwa. Dhayi kana mold inogona kugadzirwa kuti igadzire zvigadzirwa zvakasiyana-siyana, zvakaita semapaipi, ma profiles, sheet, firimu, kana granules. Maitiro ekugadzira anokanganiswa ne die geometry, die pressure, die temperature, uye melt rheology. Maitiro ekugadzira anofanira kugadziriswa kuti awane ma extrudates akafanana uye akapfava asina zvikanganiso, zvakaita se die swell, melt fracture, kana dimensional instability. Mushure memaitiro ekugadzira, ma extrudates anotonhodzwa, anochekwa, uye anounganidzwa nemidziyo iri pasi pemvura, senge calibrators, haul-offs, cutters, uye winders.
Mhedziso
Chinoburitsa screw mbiri dzine conical chishandiso chinoshanda zvakasiyana-siyana uye chinoshanda zvakanaka chekugadzira zvigadzirwa zvePVC neWPC kubva muupfu hwakasanganiswa. Chinogona kupa mabasa anodiwa ekudyisa, kunyungudutsa, kubvisa screw, uye kugadzira nenzira inogara ichidzorwa. Chinogona zvakare kugadzira zvigadzirwa zvakasiyana-siyana zvine maumbirwo akasiyana, saizi, uye mabasa, nekushandisa michina yakasiyana yeforoma neyepasi. Chinoburitsa screw mbiri dzine conical chine mabhenefiti ekubatanidza zvakanaka, kubuda kukuru, kushanda kwakasimba, uye kushanda kwenguva refu, uye chinogona kusangana nezvinodiwa zvakasiyana-siyana zvevatengi nemisika.
Kuti uwane rumwe ruzivo kana mibvunzo, ndapotataura nesu:
