Zvinoenderana nehunhu hwemapurasitiki, inzira yakaoma uye inorema kuti iite zvigadzirwa zvepurasitiki zvine imwe chimiro uye kukosha kwekushandisa.Mukugadzirwa kwemaindasitiri ezvigadzirwa zvepurasitiki, sisitimu yekugadzira yezvigadzirwa zvepurasitiki inonyanya kuumbwa nemaitiro mana anoenderera: mapurasitiki ekuumba, mechanical processing, kushongedza uye kusangana.
Mune maitiro mana aya, kuumbwa kwepurasitiki ndiyo kiyi yekugadzira mapurasitiki.Nzira dzekuumba dzinosvika makumi matatu emhando, kunyanya dzakasiyana siyana dzepurasitiki (hupfu, chidimbu, mhinduro kana kupararira) mune yaunoda chimiro chechigadzirwa kana billet.Iyo yekuumba nzira inonyanya kuenderana nerudzi rwepurasitiki (thermoplastic kana thermosetting), yekutanga fomu, uye chimiro uye saizi yechigadzirwa.Plastic processing thermoplastics nzira dzinowanzo shandiswa ndeye extrusion, jekiseni kuumba, calendering, kuvhuvhuta uye kupisa kuumbwa, epurasitiki kugadzirisa thermosetting mapurasitiki anowanzo shandisa kuumba, kutamisa kuumba, asiwo jekiseni kuumba.Laminating, kuumba, uye thermoforming vari kugadzira purasitiki panzvimbo yakati sandara.Iyo iri pamusoro pepurasitiki yekugadzirisa nzira dzinogona kushandiswa kugadzirisa rabha.Mukuwedzera, pane mvura monomer kana polymer seyakagadzirwa zvinhu zvakasvibiswa, nezvimwewo Pakati penzira idzi, extrusion uye jekiseni kuumba ndiyo inonyanya kushandiswa uye inonyanya kushandiswa kuumba nzira.
Iyo mechanic processing yekugadzira chigadzirwa chepurasitiki ndeyekukwereta nzira yepurasitiki yekugadzira simbi nehuni, nezvimwewo, kugadzira zvigadzirwa zvepurasitiki zvine saizi chaiyo kana huwandu hudiki, uye zvakare inogona kushandiswa senzira yekubatsira yekuumba, senge saw. kucheka kwema profiles akawedzerwa.Nekuda kwekuita kwakasiyana kwepurasitiki nesimbi uye huni, epurasitiki yekupisa conductivity haina kunaka, coefficient yekuwedzera kwemafuta, yakaderera modulus yekunyungudika, kana iyo yekumisikidza kana chishandiso chakanyanya kukura, chiri nyore kukonzera deformation, kucheka kupisa kuri nyore kunyungudika, uye nyore kuomerera kune chishandiso.Naizvozvo, machini epurasitiki, chishandiso chinoshandiswa uye inoenderana yekucheka kumhanya kunofanirwa kuenderana nehunhu hwepurasitiki.Inowanzo shandiswa machining nzira ndedzesaha, kucheka, kubaya, kutenderedza, kuronga, kuchera, kukuya, kukwenenzvera, kugadzira shinda nezvimwe zvakadaro.Mukuwedzera, mapurasitiki anogona kutemwa, kudhonzwa uye kusungirirwa nelaser.
Kubatana mukugadzirwa kwezvigadzirwa zvepurasitiki Nzira dzekubatanidza zvikamu zvepurasitiki ndeye welding uye kubatana.Welding nzira ndiko kushandiswa kwemhepo inopisa yemagetsi electrode welding, kushandiswa kwekupisa kunyunguduka, pamwe nepamusoro-frequency welding, friction welding, induction welding, ultrasonic welding nezvimwe zvakadaro.Iyo nzira yekubatanidza inogona kukamurwa kuita flux, resin mhinduro uye inopisa inonyungudika yakanamatira zvinoenderana neinonamatira inoshandiswa.
Chinangwa chekugadziriswa kwepamusoro pekugadzirwa kwezvigadzirwa zvepurasitiki ndeyekushongedza pamusoro pezvigadzirwa zvepurasitiki, kazhinji zvinosanganisira: mechanical modification, kureva, faira, kugaya, kupurisa uye mamwe maitiro, kubvisa burr, burr, uye kugadzirisa saizi;Kupedzisa, kusanganisira kupfekedza pamusoro pechigadzirwa nepende, kushandisa zvinonyungudutsa kuita kuti pasi rive rakajeka, uchishandisa patterned film coating pamusoro pechigadzirwa, nezvimwewo;Kushandiswa kwemavara, kusanganisira kupenda kwemavara, kudhinda uye kupisa kutsika;Gold plating, kusanganisira vacuum coating, electroplating uye kemikari sirivha plating, etc. Plastic processing inopisa stamping ndiko kutamisa ruvara aruminiyamu foil layer (kana imwe muenzaniso firimu) pane inopisa chidhindo firimu kuti workpiece pasi kudziyisa uye kumanikidzwa.Midziyo yakawanda yemumba uye zvigadzirwa zvekuvaka, zvinodiwa zvezuva nezuva, nezvimwewo, vari kushandisa nzira iyi kuwana simbi inopenya kana mapatani ehuni.
Gungano ndiko kushanda kwekuunganidza zvikamu zvepurasitiki kuita zvigadzirwa zvakakwana negluing, welding uye mechanical connection.Semuenzaniso, mapepa epurasitiki anounganidzwa mumapuranga epurasitiki nemagonhi kuburikidza nekucheka, welding, kuchera uye mamwe matanho.
