Polymer Extrusion Process - Plastic Extrusion

Maitiro epolymer extrusion anosanganisira kutora mbishi zvinhu uye kugadzira chigadzirwa chinogona kuumbwa kuita chakasiyana chimiro chehurefu hwakasiyana, maumbirwo uye mavara.Iwo maprofiles anogoneka zvakanyanya uye anogona kugadzirwa kubva kunenge chero mhando yerabha.Pane maitiro maviri erabha extrusion;inoenderera mberi mu-line kurapwa uye off-line kurapwa.

Inoenderera mumutsara kurapa extrusion:

• * Mukuita uku rabha inopisa inofambiswa nepasi murukova rwakafanana uye inofamba nemu'mugero unorapa' unokwidza chigadzirwa kusvika kune yakafanira tembiricha yekupisa uye inochengetedza tembiricha iyoyo kutozosvikira kurapa kwapera.Pane nzira dzakawanda dzinogona kushandiswa kugadzira 'nzira yekurapa' inosanganisira;high velocity inopisa mhepo, microwave oveni, inopisa mvura inoporesa svikiro (LCM) kana mubhedha unoyerera wegirazi Ballotini bead.Hurefu hwemugero hunotorwa mukutariswa pamwe nekumhanya kuverengera tembiricha mukati mekuita vulcanizing.Sezvo rabha yakarapirwa ichibuda mugero inoendeswa mugero rekutonhodza umo rabha rinotonhodzwa uye zvinosara zvobviswa.Iyo yekumhanyisa iyo chigadzirwa chinofamba nemugero yekutonhora inofambiswa neanodhonza pamagumo emutsara kuchengetedza kugadzikana kwese.
• *Zvakanakira: kugona kuburitsa hurefu husina kuputika, kuwedzera kukurumidza kwekugadzira, kushanda kushoma, uye kushandiswa kwakanaka kwesimba nenzvimbo.Iyi nzira inobvumirawo kusanganiswa kwezvinhu zvakawanda.Iyi nzira ine zvimwe zvinogumira.Kazhinji mutengo wezvigadzirwa zvakakwirisa, uye panogona kuve nehukuru uye zvimiro zvinogumira.

Off-line kurapa extrusion:

• Nenzira iyi nzira yekurapa inobatsirwa ne autoclaves.Iyo rabha inodziya inofambiswa nemufa uye yobva yafumurwa kune-yakanyanya-kudzvanywa steam kuitira kuti iwane yakakodzera tembiricha inopisa.Kupisa kunochengetwa kusvikira kemikari inogadzirisa yapera.Nzira yekurapa isati yatanga iyo isina kupora, yakaumbwa nechubhu, chigadzirwa chinochengetedzwa pamusoro pemandrel kumanikidza rabha kuchengetedza chimiro chakasiyana panguva yekurapa.

Plastic Extrusion Process

Plastic extrusion inzira yekushandura zvinhu zvepurasitiki kubva pakasimba kuenda kumvura uye kuzvigadzirisa sezvikamu zvakapedzwa.Chekutanga, maplastic pellets anodyiswa kubva kune hopper kupinda mune jekete screw.Sezvo screw inotenderera paaxis yayo, inotakura, inonyungudika, uye inodzvanya plastiki.Kubva ipapo, simbi yakanyungudutswa inomanikidzwa kuburikidza nedhidhi inoiumba kuita yakatsanangurwa muchinjiko-chikamu, ichigadzira zvikamu zvine hurefu hunogona kuita hwakakura.Munguva ye extrusion, mapurasitiki anoshanduka kubva pakusimba kuenda kumvura uye kudzoka zvakare pasina kupira hunhu hwawo hwakasiyana.Nekuda kweizvozvo, zvimedu zvezvimedu zvinogona kuve pasi uye kuwedzererwa zvakare nekuderera kudiki, zvichiita kuti extrusion ive nzira yakakurumbira yekudzikisa kana kudzokorora tsvina yepurasitiki.
