A conical twin screw extruderimhando yetwin screw extruder ine screws mbiri dzakarongwa mune conical chimiro, ichienda kumucheto wekubuda kweextruder. Iyi dhizaini inopa kudzikiswa zvishoma nezvishoma muiyo screw chiteshi vhoriyamu, zvichikonzera kuwedzera kudzvanywa uye kuvandudzwa kusanganiswa. Iyo conical twin screw extruder inonyanya kuumbwa nebarrel screw, gear transmission system, kuwanda kwekudya, vacuum exhaust, kudziyisa, kutonhora uye magetsi ekudzora zvinhu.
A conical twin screw extruder yakakodzera kugadzira PVC zvigadzirwa kubva musanganiswa poda. PVC inonzi thermoplastic polymer ine huwandu hwakasiyana hwekushandisa mumaindasitiri akasiyana, sekuvaka, kurongedza, magetsi, mota, uye zvekurapa. Nekudaro, PVC haienderane nemamwe akawanda mapolymer uye ekuwedzera, uye inoda akakosha magadzirirwo matekiniki kuti uwane inodiwa zvivakwa uye kuita. Iyo conical twin screw extruder inogona kupa inodiwa kusanganisa, kunyunguduka, devolatilization, uye homogenization yePVC uye yekuwedzera kwayo nenzira inoenderera uye inoshanda.
A conical twin screw extruder zvakare yakakosha midziyo yeWPC hupfu extrusion. WPC inomirira huni-plastic composite, inova zvinhu zvinosanganisa hupfu hwehuni kana hupfu hwehuni ne thermoplastic polymers, sePVC, PE, PP, kana PLA. WPC ine zvakanakira zvese huni nemapurasitiki, senge kusimba kwepamusoro, kusimba, kuramba mamiriro ekunze, uye kudzokorora. Iyo conical twin screw extruder inogona kugadzira WPC hupfu ine yakakwira kubuda, yakagadzikana kumhanya, uye hupenyu hurefu hwebasa.
Iine akasiyana mold uye yakadzika michina, conical twin screw extruder inogona kugadzira akasiyana PVC neWPC zvigadzirwa, senge pombi, sirin'i, mafafitera profiles, sheet, decking, uye granules. Zvigadzirwa izvi zvine maumbirwo akasiyana, saizi, uye mabasa, uye zvinogona kusangana nezvinodiwa zvakasiyana zvevatengi nemisika.
Tsanangudzo Yenzira
Maitiro econical twin screw extrusion anogona kukamurwa kuita matanho mana makuru: kudya, kunyungudika, devolatilization, uye kuumbwa.
Kudyisa
Nhanho yekutanga yeconical twin screw extrusion ndeyekudya. Mune ino nhanho, zvigadzirwa, zvakaita sePVC kana WPC hupfu, uye zvimwe zvinowedzera, senge zvinosimbisa, mafuta ekuzora, mafirita, pigment, uye modhifita, zvinoiswa meter uye kupihwa muextruder nemidziyo yekudyisa yakasiyana, senge screw augers, vibratory. matireyi, mabhande ekuyeresa, uye pombi dzejekiseni. Chiyero chekudyisa uye kunyatsoita zvinhu zvakakosha zvinokanganisa kunaka uye kuenderana kwezvigadzirwa zvekupedzisira. Iyo mbishi inogona kuve isati yasanganiswa uye kudyiswa, kana zvakasiyana uye zvakateedzana metered mukati meiyo extruder, zvichienderana nekuumbwa uye zvinodiwa zvezvigadzirwa.
Melting
Chikamu chechipiri che conical twin screw extrusion iri kunyunguduka. Mune ino nhanho, iyo mbishi zvinhu zvinofambiswa, kudzvanywa, uye kupiswa neinotenderera screws uye mbiya heaters, uye kushandurwa kubva kusimba kuenda kumvura. Iyo yekunyunguduka inosanganisira zvese zvinopisa uye zvemuchina simba rekuisa, uye zvinokanganiswa nekumhanya kwescrew, screw kumisikidzwa, tembiricha yebhare, uye zvinhu zvenyama. Kunyunguduka kwakakoshawo pakupararira uye kugovaniswa kwezvinowedzera mupolymer matrix, uye kutangwa kwemaitiro emakemikari, senge kuchinjika, kubatanidza, kana kukanganisa, izvo zvinogona kuitika mukunyungudika. Kunyunguduka kunofanirwa kudzorwa nekuchenjerera kudzivirira kupisa, kuveura zvakanyanya, kana kunyungudika kwemidziyo, izvo zvinogona kuguma nekuipa kwechigadzirwa kunaka uye kushanda.
Devolatilization
Nhanho yechitatu ye conical twin screw extrusion ndeye devolatilization. Mune ino nhanho, izvo zvinoputika zvikamu, senge hunyoro, mhepo, monomers, zvinonyungudutsa, uye zvigadzirwa zvekuora, zvinobviswa kubva mukunyunguduka nekuisa vacuum pama vent ports padivi pe extruder barrel. Iyo devolatilization maitiro akakosha pakuvandudza kunaka kwechigadzirwa uye kugadzikana, pamwe nekudzikisa kukanganiswa kwezvakatipoteredza uye njodzi dzehutano dzeextrusion process. Iyo devolatilization maitiro inoenderana neiyo screw dhizaini, vacuum level, melt viscosity, uye hunhu hwezvinhu. Iyo devolatilization maitiro anofanirwa kuvandudzwa kuti awane kubviswa kwakakwana kwezvinoputika pasina kukonzeresa kupumha furo, mafashama emhepo, kana kunyungudika kunyungudika.
Shaping
Yechina uye yekupedzisira nhanho yeconical twin screw extrusion iri kuumba. Muchikamu chino, kunyunguduka kunowedzerwa kuburikidza nekufa kana mold iyo inotarisa chimiro uye kukura kwechigadzirwa. Iyo inofa kana mold inogona kugadzirwa kugadzira zvigadzirwa zvakasiyana, senge pombi, profiles, sheet, firimu, kana granules. Iyo yekugadzira maitiro inopesvedzerwa neiyo die geometry, kufa kumanikidza, kufa tembiricha, uye kunyunguduka rheology. Iyo yekugadzira maitiro inofanirwa kugadziridzwa kuti iwane yunifomu uye yakatsetseka extrudates isina kuremara, senge kufa kuzvimba, kunyungudika kunyungudika, kana dimensional kusagadzikana. Mushure mekuumbwa, maextrudates anotonhodzwa, anochekwa, uye anounganidzwa nemidziyo yepasi, senge macalibrator, mahul-offs, cutters, uye winders.
Mhedziso
A conical twin screw extruder chishandiso chinogoneka uye chinoshanda chekugadzira PVC neWPC zvigadzirwa kubva muhupfu hwakasanganiswa. Inogona kupa mabasa anodiwa ekudyisa, kunyunguduka, devolatilization, uye kuumba nenzira inoenderera uye inodzorwa. Inogonawo kugadzira zvigadzirwa zvakasiyana-siyana zvine maumbirwo akasiyana, saizi, uye mabasa, nekushandisa akasiyana mold uye yakadzika midziyo. Iyo conical twin screw extruder ine zvakanakira kusanganisa kwakanaka, yakakura kubuda, yakagadzikana kumhanya, uye hupenyu hwesevhisi hurefu, uye inogona kusangana nezvinodiwa zvakasiyana zvevatengi nemisika.
Kuti uwane rumwe ruzivo kana kubvunza, ndapotataura nesu:
