Ukubunjwa komjovo okusiza ngegesi Lobu buchwepheshe bomjovo obuthuthukisiwe ukujova i-nitrogen ephezulu ingcindezi ngqo kupulasitiki oplastikhi embotsheni yesikhunta ngokusebenzisa isilawuli esisizwa ngegesi (ingxenye elawula ingcindezi), ukuze ingxenye yengxenye yepulasitiki inwebeke futhi ibe yize , kepha ingaphezulu lomkhiqizo lisalondolozwa. Nokuma kahle.
A. Izinzuzo zobuchwepheshe bokujola obusizwe ngegesi:
1.Gcina izinto zokusetshenziswa zepulasitiki, izinga lokonga lingafinyelela kuma-50%.
2. Nciphisa isikhathi somjikelezo womkhiqizo.
3. Nciphisa ukucindezelwa komshini wokubumba umjovo ufike kuma-60%.
4. Thuthukisa impilo yokusebenza komshini wokubumba umjovo.
5. Yehlisa ingcindezi esemgodini, unciphise ukulahleka kwesikhunta futhi wandise impilo yokusebenza kwesikhunta.
6. Kweminye imikhiqizo yepulasitiki, isikhunta singenziwa ngezinto zensimbi ye-aluminium.
7. Nciphisa ukucindezeleka kwangaphakathi komkhiqizo.
8. Xazulula futhi ususe inkinga yamamaki okusinki ebusweni bomkhiqizo.
9.Lula umklamo onzima womkhiqizo.
10. Nciphisa ukusetshenziswa kwamandla komshini wokubumba umjovo.
11. Nciphisa izindleko zokutshala imali zemishini yokubumba umjovo kanye nezikhunta ezikhulayo.
12. Nciphisa izindleko zokukhiqiza.
B. Izinzuzo zobuchwepheshe bokujova obusizwe ngegesi:
Eminyakeni yamuva nje, ubuchwepheshe obusizwa ngegesi bokujova umjovo busetshenzisiwe ekukhiqizeni izingxenye eziningi zepulasitiki, ezifana nethelevishini noma okuvalelwayo, imikhiqizo epulasitiki yezimoto, ifenisha, amakhabethe kanye nezidingo zansuku zonke, izinhlobo ezahlukahlukene zamabhokisi epulasitiki namathoyizi, njalonjalo .
Uma kuqhathaniswa nomjovo ovamile ovuthiwe, ubuchwepheshe obusizwa ngegesi bokujova ubuchwepheshe bunezinzuzo eziningi ezingenakuqhathaniswa. Ayikwazi ukunciphisa kuphela izindleko zokukhiqiza zemikhiqizo yepulasitiki, kepha futhi ithuthukise ezinye zezinto zayo. Ngaphansi kwesimo sokuthi izingxenye zingahlangabezana nezidingo ezifanayo zokusetshenziswa, ukusetshenziswa kwe-injection-assisted injection molding kungagcina kakhulu izinto zepulasitiki, futhi izinga lokonga lingafika ku-50%.
Ngakolunye uhlangothi, ukuncipha kwenani lezinto ezisetshenzisiwe zepulasitiki kunciphisa isikhathi sokuxhumanisa ngakunye emjikelezweni wonke wokubumba; ngakolunye uhlangothi, ukuncipha nokuguqulwa kwengxenye kuthuthukiswe kakhulu ngokwethulwa kwegesi enomfutho ophakeme ngaphakathi kwengxenye, ngakho-ke isikhathi sokubamba umjovo, Ingcindezi yokubamba umjovo ingancishiswa kakhulu.
Injini esizwa ngegesi isetshenzisiwe inciphisa ingcindezi yokusebenza kohlelo lokujova kanye nohlelo lokuqinisa umshini womjovo, okunciphisa ngokufanayo ukusetshenziswa kwamandla ekukhiqizeni futhi kukhulise impilo yesevisi yomshini wokubumba umjovo kanye nesikhunta. Ngasikhathi sinye, ngoba ingcindezi yesikhunta inciphile, okokusebenza kwesikhunta kungabiza kancane. Izingxenye ezicutshungulwa ubuchwepheshe obusizwa yigesi zinesakhiwo esiyize, esingagcini nje ngokunciphisa izakhiwo zemishini yezingxenye, kodwa futhi ziyazithuthukisa, nakho okulusizo ekusimameni kobukhulu bezingxenye.
Inqubo yomjovo osizwa ngegesi inzima kakhulu kunomjovo ojwayelekile. Ukulawulwa kwezingxenye, isikhunta nezinqubo kuhlaziywa ngokulingisa okusizwa yikhompyutha, kanti izidingo zohlelo lomshini wokujova umjovo zilula. Njengamanje, ngaphezu kwe-80% yemishini yokubumba umjovo iyasetshenziswa. Umshini wokubumba umjovo ungafakelwa uhlelo lokubumba umjovo osizwa ngegesi ngemuva kokuguqulwa okulula.
Azikho izidingo ezikhethekile zezinto zokusetshenziswa. Ama-thermoplastics ajwayelekile kanye namapulasitiki wobunjiniyela afaneleka ekubunjweni komjovo okusizwa ngegesi. Ngenxa yezinzuzo zobuchwepheshe bokujola obusizwe ngegesi ezicini eziningi, ngasikhathi sinye, inezinhlobo ezahlukahlukene zezicelo futhi ayidingi imishini eningi nezinto zokusetshenziswa. Ngakho-ke, ekuthuthukisweni kwesikhathi esizayo, ukusetshenziswa kwalobu buchwepheshe embonini yokubumba umjovo kuzoba ngokuya ngokwanda.
C.Ukusetshenziswa kobuchwepheshe bokujova obusizwe ngegesi:
Ubuchwepheshe bokubumba umjovo obusetshenziswa ngegesi bungasetshenziswa emikhiqizweni ehlukahlukene yepulasitiki, njengamathelevishini, amafriji, ama-air conditioner, noma okuvalelwayo, imikhiqizo yezimoto zepulasitiki, ifenisha, izindlu zangasese, izitsha zasekhishini, izinto zasendlini nezidingo zansuku zonke, izinhlobo ezahlukahlukene zamabhokisi epulasitiki, Baby imikhiqizo ibhokisi amathoyizi nokunye.
Ngokuyinhloko wonke ama-thermoplastics asetshenziselwa umjovo wokubumba (aqiniswa noma cha), nama-plastiki ejwayelekile wobunjiniyela (njenge-PS, HIPS, PP, ABS ... PES) alungele ubuchwepheshe bokusiza ngomjovo obusekelwa ngegesi.
