Ngokweempawu zendalo zeplastiki, yinkqubo enzima kwaye inzima ukuyenza ibe yimveliso yeplastiki enemilo ethile kunye nexabiso lokusebenzisa.Kwimveliso yemveliso yeemveliso zeplastiki, inkqubo yokuvelisa iimveliso zeplastiki ikakhulu iqulunqwe iinkqubo ezine eziqhubekayo: ukwenza iplastiki, ukusetyenzwa ngoomatshini, ukuhlobisa kunye nokuhlanganisana.
Kwezi nkqubo zine, ukubumba iplastiki yeyona nto iphambili ekusetyenzweni kweplastiki.Iindlela zokubumba ezininzi njengeentlobo ezingama-30, ubukhulu becala iintlobo ezahlukeneyo zeplastiki (umgubo, amasuntswana, isisombululo okanye ukusasazwa) kwimilo efunekayo yemveliso okanye ibhilithi.Indlela yokubumba ixhomekeke ikakhulu kuhlobo lweplastiki (i-thermoplastic okanye i-thermosetting), ifom yokuqala, kunye nemilo kunye nobukhulu bemveliso.Iindlela zePlastiki zokulungisa i-thermoplastics ezisetyenziswa ngokuqhelekileyo zi-extrusion, ukubumba inaliti, i-calendering, ukubunjwa kokuvuthela kunye nokubumba okutshisayo, iiplastiki zeplastiki zokulungisa i-thermosetting ngokubanzi zisebenzisa ukubumba, ukudlulisa ukubumba, kodwa kunye nokubumba inaliti.I-Laminating, ukubumba, kunye ne-thermoforming zenza iplastiki kumphezulu osicaba.Ezi ndlela zeplastiki zingentla zingasetyenziselwa ukusetyenzwa kwerabha.Ukongeza, kukho i-monomer yolwelo okanye i-polymer njengento yokugalela izinto ekrwada, njl.njl. Phakathi kwezi ndlela, i-extrusion kunye ne-injection molding zezona zisetyenziswayo kunye neendlela ezisisiseko zokubumba.
Ukusetyenzwa ngoomatshini bemveliso yeplastiki kukuboleka indlela yokwenziwa kweplastiki yentsimbi kunye neenkuni, njl. njl., ukwenza iimveliso zeplastiki ezinobungakanani obuchanekileyo okanye ubungakanani obuncinci, kwaye zinokusetyenziswa njengenkqubo encedisayo yokubumba, njengesarha. ukusika iiprofayili ezikhutshiweyo.Ngenxa yokusebenza okwahlukeneyo kweplastiki kunye nentsimbi kunye nemithi, iplastiki ye-thermal conductivity ihlwempuzekile, i-coefficient yokwandisa i-thermal, i-modulus ephantsi yokuqina, xa i-fixture okanye uxinzelelo lwesixhobo lukhulu kakhulu, kulula ukubangela ukuguqulwa, ukusika ubushushu kulula ukunyibilika, kunye kulula ukubambelela kwisixhobo.Ke ngoko, umatshini weplastiki, isixhobo esisetyenzisiweyo kunye nesantya sokusika esihambelanayo kufuneka silungelelanise neempawu zeplastiki.Iindlela zoomatshini eziqhelekileyo ezisetyenziswayo zisarha, ukusika, ukubethelela, ukujika, ukucwangcisa, ukugrumba, ukucola, ukupolisha, ukusetyenzwa kwentambo njalo njalo.Ukongeza, iiplastiki zinokusikwa, zigrunjwe kwaye zifakwe nge-laser.
Ukudibanisa kwimveliso yeemveliso zeplastiki Iindlela zokudibanisa iinxalenye zeplastiki zi-welding kunye nokudibanisa.Indlela ye-welding kukusetyenziswa kwe-welding ye-electrode eshushu yomoya, ukusetyenziswa kwe-welding eshushu ye-melt, kunye ne-high-frequency welding, i-friction welding, i-induction welding, i-ultrasonic welding kunye nokunye.Indlela yokudibanisa inokwahlulwa ibe yi-flux, isisombululo se-resin kunye ne-adhesive eshushu enyibilikayo ngokwe-adhesive esetyenzisiweyo.
Injongo yokuguqulwa kwendawo yokuveliswa kweemveliso zeplastiki kukuhlobisa umgangatho weemveliso zeplastiki, ngokuqhelekileyo kubandakanya: ukuguqulwa komatshini, oko kukuthi, ifayile, ukugaya, ukupolisha kunye nezinye iinkqubo, ukususa i-burr, i-burr, kunye nokulungiswa kobungakanani;Ukugqiba, kubandakanywa ukugubungela umphezulu wemveliso ngepeyinti, ukusebenzisa i-solvents ukwenza ubuso bukhanye ngakumbi, usebenzisa ifilimu enepateni yokugqoka ubuso bemveliso, njl.;Ukusetyenziswa kombala, kubandakanywa ukupeyinta kombala, ukuprinta kunye nesitampu esishushu;Ukufakwa kwegolide, kubandakanywa ukugquma kwe-vacuum, i-electroplating kunye ne-chemical silver plating, njl njl.Uninzi lwezixhobo zendlu kunye neemveliso zokwakha, iimfuno zemihla ngemihla, njl., zisebenzisa le ndlela ukufumana i-metallic luster okanye iipateni zokhuni.
INdibano kukusebenza kokudibanisa iinxalenye zeplastiki kwiimveliso ezipheleleyo nge-gluing, i-welding kunye nokudibanisa ngomatshini.Ngokomzekelo, iiprofayili zeplastiki zihlanganiswe kwiifestile zeplastiki kunye neengcango ngokusebenzisa i-sawing, i-welding, i-drilling kunye namanye amanyathelo.
