Ukubumba umjovo, ukukhuluma nje, kuyinqubo yokusebenzisa izinto zensimbi ukwakha imbobo esesimweni sengxenye, ukufaka ingcindezi kupulasitiki owuketshezi oluncibilikisiwe ukuwujova emgodini nokugcina ukucindezela isikhathi esithile, bese upholisa ipulasitiki iyancibilika futhi ikhiphe ingxenye eqediwe. Namuhla, ake sikhulume ngamasu amaningana okubumba avamile.
1. Ukukhihliza amagwebu
Ukubumba igwebu kuyindlela yokucubungula eyakha isakhiwo esinezimbotshana ngaphakathi kwepulasitiki ngezindlela ezingokomzimba noma zamakhemikhali.
Inqubo:
a. Ukondla: Gcwalisa isikhunta ngezinto ezingavuthiwe ukuze kukhihlizwe amagwebu.
b. I-clamping heat: Ukushisa kuthambisa izinhlayiya, kuhwamulise i-ejenti ekhipha amagwebu kumaseli, futhi kuvumela isisetshenziswa sokushisisa ukuthi singene ukuze siqhubeke sandise izinto zokusetshenziswa. Khona-ke ukubunjwa kuvinjelwe yi-mold cavity. Impahla eluhlaza enwetshiwe igcwalisa yonke imbobo yesikhunta kanye nezibopho zizonke.
c. Ukupholisa ukubumba: Vumela umkhiqizo uphole futhi uthuthuke.
Izinzuzo:Umkhiqizo unomphumela ophezulu we-thermal insulation kanye nokumelana nomthelela omuhle.
Ububi:Izimpawu zokugeleza kwama-radial akheka kalula ngaphambili kokugeleza kwezinto ezibonakalayo. Kungakhathaliseki ukuthi igwebu lamakhemikhali noma i-micro-foaming, kukhona izimpawu zokugeleza kwe-radial ezicacile. Izinga eliphezulu lezingxenye liphansi, futhi alifaneleki izingxenye ezinezidingo zekhwalithi ephezulu.
2. Ukulingisa
Obeye aziwe njengoukubunjwa kokubunjwa, inqubo lapho i-polymer ewuketshezi ye-resin eluhlaza ifakwa esikhunjini ukuze isabele futhi iqine ngaphansi kwengcindezi evamile noma indawo yokucindezela okuncane. Ama-nylon monomers nama-polyamides Ngokuthuthuka kobuchwepheshe, umqondo wokulingisa wendabuko usushintshile, futhi izixazululo ze-polymer kanye nokuhlakazeka okuhlanganisa okunamathiselwe kwe-PVC nezisombululo nakho kungasetshenziswa ekubumbeni.
Ukubunjwa kwe-cast kwaqala ukusetshenziselwa ama-thermosetting resins futhi kamuva kwasetshenziselwa izinto ze-thermoplastic.
Inqubo:
a. Ukulungiselela isikhunta: Ezinye zidinga ukushisisa. Hlanza isikhunta, sebenzisa ukukhululwa kwesikhunta kusengaphambili uma kunesidingo, bese ushisa ngaphambili isikhunta.
b. Lungisa uketshezi oluphonsayo: Hlanganisa izinto zokusetshenziswa zepulasitiki, i-ejenti yokwelapha, i-catalyst, njll., khipha umoya bese uwufaka esikhunjeni.
c. Ukukhipha kanye nokwelapha: Impahla eluhlaza yenziwa i-polymerized futhi yelapheka ekubunjweni ukuze ibe umkhiqizo. Inqubo yokuqina iqedwa ngaphansi kokushisa kwengcindezi evamile.
d. Ukubhidliza: Ukubunjwa ngemva kokwelapha kuqediwe.
Izinzuzo:Imishini edingekayo ilula futhi akukho ngcindezi edingekayo; izidingo zamandla esikhunta aziphezulu; umkhiqizo ufana futhi ukucindezeleka kwangaphakathi kuphansi; ubukhulu bomkhiqizo buvinjelwe kancane, futhi imishini yokucindezela ilula; izidingo zamandla esikhunta ziphansi; i-workpiece ifana futhi ukucindezeleka kwangaphakathi kuphansi, imikhawulo yesayizi ye-Workpiece mincane futhi akukho mishini yokucindezela edingekayo.
Ububi:Umkhiqizo uthatha isikhathi eside ukwakha futhi ukusebenza kahle kuphansi.
Isicelo:Amaphrofayili ahlukahlukene, amapayipi, njll. I-Plexiglass iwumkhiqizo ojwayelekile wokuphonsa wepulasitiki. I-Plexiglass iwumkhiqizo wakudala wepulasitiki wokulingisa.
3. Ukubunjwa kokucindezela
Eyaziwa nangokuthi ukubunjwa kwefilimu yepulasitiki yokudlulisa, kuyindlela yokubumba yamapulasitiki e-thermosetting. I-workpiece iyelapheka futhi yakheke emgodini wesikhunta ngemuva kokufudumeza nokucindezela bese kufudumeza.
Inqubo:
a. Ukushisa okuphakelayo: Shisisa futhi uthambise izinto ezingavuthiwe.
b. Ukucindezela: Sebenzisa i-flap noma i-plunger ukuze ucindezele into eluhlaza ethambile futhi encibilikisiwe esikhunjeni.
c. Ukwakha: Ukupholisa kanye nokudilizwa ngemva kokubunjwa.
Izinzuzo:Amaqoqo amancane omsebenzi, izindleko zabasebenzi ezincishisiwe, ukucindezeleka kwangaphakathi okufanayo, nokunemba okuphezulu kobukhulu; ukugqoka okuncane kwesikhunta kungakha imikhiqizo enokufakwa okuhle noma okuthuthukisa ukushisa.
Ububi:Izindleko eziphezulu zokukhiqiza isikhunta; ukulahlekelwa okukhulu kwezinto zokusetshenziswa zepulasitiki.
