Isixhumanisi esiyinhloko ekucutshungulweni kwepulasitiki.Kudingeka izinhlobo ezahlukene zemikhiqizo yepulasitiki noma ingxenye yomumo.Kunezindlela eziningi zokubumba ze-30, ezincike kakhulu kuhlobo lwepulasitiki, ukukhetha kusuka efomini kanye nokuma nobukhulu bomkhiqizo.Izindlela zokucubungula ipulasitiki ezivame ukusetshenziswa yi-thermoplastic extrusion, ukubumba umjovo, i-calendering, ukubunjwa kwe-blow kanye ne-thermoforming.Ukubunjwa kwepulasitiki ye-thermosetting okuvame ukusetshenziswa ekucubunguleni ipulasitiki nakho kusebenzisa ukubumba kokudlulisa, ukubumba umjovo, ukubumba i-laminate kanye ne-thermoforming.Ngaphezu kwalokho, kunezindlela ezinjengokuphonsa ngama-monomers angama-liquid noma ama-polymers njengezinto zokusetshenziswa.Phakathi kwalezi zindlela, ukubunjwa kwe-extrusion kanye nomjovo kusetshenziswa kaningi, futhi kuyindlela eyisisekelo kakhulu.
Insimbi nezinkuni zisetshenziselwa ukucubungula amapulasitiki.Njengoba izakhiwo zepulasitiki zihlukile kulezo zensimbi nezinkuni, ukungahambi kahle kwe-thermal, i-coefficient ephansi yokwanda okushisayo, i-modulus ephansi ye-elasticity, ukucindezela okukhulu kwezinto ezilungiswayo noma amathuluzi, kulula ukubangela ukuguqulwa, nokusika ukushisa kulula ukuncibilika., Futhi kulula ukunamathela ithuluzi.Ngakho-ke, imishini yepulasitiki, amathuluzi okusika kanye nesivinini esihambelanayo sokusika kufanele sivumelane nezici zepulasitiki, nezinye izindlela zokucubungula ezivamile ziyi-sawing, ukusika, ukubhoboza, ukuguqula, ukuhlela, ukubhola, ukugaya, ukupholisha, ukucutshungulwa kwentambo, njll Ngaphezu kwalokho, amapulasitiki futhi ingasikwa nge-laser, isitembu, futhi ishiselwe.
Kunezindlela zokushisela kanye nezokunamathela zokucubungula ipulasitiki.Ukushisela ukusetshenziswa komoya oshisayo ukushisela ama-electrode, ukushisela okushisayo kusetshenziswa ukushisa, nezindlela zokushisela ezifana ne-high frequency welding, friction welding, induction welding, i-ultrasonic welding kanye ne-laser welding.Ama-Adhesives ahlukaniswe ama-solvents, izixazululo ze-resin kanye nezinamathelisi ezincibilikayo ezishisayo.
I-Bonding, i-welding kanye nezindlela zokuxhuma ngomshini zivumela ukuhlangana kwezingxenye zepulasitiki zibe umsebenzi ophelele womkhiqizo.
Singenza imikhiqizo yepulasitiki yanoma yimuphi usayizi, singochwephesheisikhuntaumkhiqizi
