Izici zenqubo yokubumba ejikelezayo

Inqubo yokubumba ejikelezayo yaziwa nangokuthi ukubumba okujikelezayo, ukubumba okujikelezayo.Kuyindlela yokubumba engenalutho ye-thermoplastic.
Ukubumba okujikelezayo kuyinqubo enezinjongo eziningi yokukhiqiza izingxenye zepulasitiki ezingenalutho.Inqubo yokubumba ejikelezayo isebenzisa ukushisisa nokuzungezisa ngokuhambisana nezimbazo ezimbili ukukhiqiza izingxenye ezingenalutho ezingenalutho.Ipulasitiki encibilikisiwe ijovwa esibunjeni esijikelezayo, futhi amandla aphakathi nendawo aphoqa ipulasitiki encibilikisiwe ukuthi inamathele odongeni lwangaphakathi lwesikhunta.
Okusho ukuthi, i-powder noma into yokunamathisela ijova esikhunjeni kuqala, futhi impahla imbozwa ngokulinganayo ngembobo yesikhunta futhi inyibilikiswe ngamandla ayo adonsela phansi namandla aphakathi nendawo ngokushisisa isikhunta nokugingqika nokuzungeza izikhombisi-ndlela eziqondile nezivundlile. , bese idilizwa ukuze uthole imikhiqizo engenalutho ngemva kokupholisa.Ngenxa yokuthi ijubane elijikelezayo lokubunjwa okujikelezayo aliphezulu, imishini ilula, umkhiqizo cishe awunakho ukucindezeleka kwangaphakathi, futhi akulula ukuguqula nokucwilisa.Ekuqaleni, yayisetshenziselwa ikakhulukazi ukukhiqizwa kwepulasitiki ye-PVC yamathoyizi, amabhola enjoloba, amabhodlela neminye imikhiqizo emincane.Muva nje, ibuye isetshenziswe kabanzi emikhiqizweni emikhulu.Ama-resin asetshenziswayo afaka i-polyamide, i-polyethylene, i-polystyrene polycarbonate eguquliwe, njll.
Kufana nokusakazwa kwe-rotary, kodwa impahla esetshenzisiwe ayilona uketshezi, kodwa i-sintered dry powder.Inqubo iwukufaka impushana esikhunjeni futhi iyenze ijikeleze izimbazo ezimbili ezihambisanayo.Umkhiqizo ongenalutho ungatholakala ekubunjeni ngokufudumeza nokuhlanganisa ngokulinganayo odongeni lwangaphakathi lwesikhunta, bese upholisa.
Kwaziwa nangokuthi ukubumba okujikelezayo noma ukubumba okujikelezayo.Ipulasitiki yempushana (njenge-LLDPE) yengezwa esikhunjeni esivaliwe.Isikhunta siyashisisa ngenkathi sijikeleza.Ipulasitiki iyancibilika futhi inamathele ebusweni besikhunta ngokulinganayo.Ngemva kokuba isikhunta sesipholisiwe, imikhiqizo yepulasitiki engenalutho enesimo esifanayo nesikhunta sesikhunta ingatholakala, njengezikebhe, amabhokisi, imiphongolo, imicengezi, amathini, njll. Ngokuvamile kuhlanganisa ukuphakela, ukubekwa uphawu kwesikhunta, ukushisa, ukupholisa, ukudiliza, ukuhlanza isikhunta nezinye izinyathelo eziyisisekelo.Le ndlela inezinzuzo zokushwabana okuncane, ukulawula kalula ukuqina kodonga kanye nezindleko eziphansi zokukhunta, kodwa ukusebenza kahle kokukhiqiza okuphansi.

Izici eziyinhloko zenqubo yokujikeleza yokubumba yilezi ezilandelayo:

I-1.Izindleko zesikhunta esijikelezayo ziphansi - ngemikhiqizo yobukhulu obufanayo, izindleko zesikhunta esijikelezayo mayelana ne-1 / 3 kuya ku-1 / 4 yaleyo yokubunjwa kokushaywa nokubunjwa komjovo, okulungele ukubumba imikhiqizo emikhulu yepulasitiki.

2.Amandla onqenqema lomkhiqizo ojikelezayo alungile - ukubumba okujikelezayo kungafinyelela ukushuba konqenqema lomkhiqizo okungaphezu kuka-5 mm, kuxazulule ngokuphelele inkinga yonqenqema lomkhiqizo olungenalutho.

I-3.Ukubumba okujikelezayo kungabeka ama-inlay ahlukahlukene.

I-4.Umumo wemikhiqizo yokubumba ejikelezayo ingaba yinkimbinkimbi kakhulu, futhi ubukhulu bungaba ngaphezu kuka-5 mm.

I-5.Ukubumba okujikelezayo kungakhiqiza imikhiqizo evaliwe ngokuphelele.

I-6.Imikhiqizo yokubumba ejikelezayo ingagcwaliswa ngezinto ezigwebu ukuze kuzuzwe ukushisa okushisayo.

I-7.Ubukhulu bodonga bemikhiqizo yokubumba ejikelezayo ingalungiswa ngokukhululekile (ngaphezu kuka-2mm) ngaphandle kokulungisa isikhunta.
