Ukulawula izinga lokushisa ngaphambi kokushisa Enqubweni Yokucwilisa Umbhede Owuketshezi
Isendlalelo Isingeniso
Enqubweni yokucwilisa embhedeni emanzi , amandla okushisa ento yokusebenza asetshenziswa ukuncibilikisa i- thermoplastic powder nokufeza ukujiya kanye nekhwalithi yokucwilisa oyifunayo. Ngakho-ke, ukunquma izinga lokushisa elifanele lokushisa kwento yokusebenza kubalulekile. Izinga lokushisa lokushisa kwangaphambi kwesikhathi kufanele libe phezulu kancane kunezinga lokushisa lokuncibilika kwe-thermoplastic powder. Uma liphezulu kakhulu, ukukhubazeka kokugeleza kungase kwenzeke ngenxa yokucwilisa okujiyile kakhulu noma ukuqhekeka kwe-polymer resin, okuholela kumabhamuza, ukuphuzi noma ukusha. Ngakolunye uhlangothi, uma liphansi kakhulu, ukuncibilika okunganele kuzoholela ekucwilisweni okuncane okune-surface pocking noma ukungapheleli okwehluleka ukufeza izinhloso zokucwilisa.
Ngokuvamile, izinga lokushisa langaphambi kokushisisa le-workpiece lithonywa yizinto ezifana nempahla yalo, usayizi, ukwakheka, ukusebenza kwempushana ye-thermoplastic, ukujiya koqweqwe oludingekayo, isikhathi sokushisa, nobude besikhathi sokucwiliswa. Kodwa-ke, ekusebenzeni okungokoqobo, ama-workpieces ayahluka kakhulu ngokobukhulu, ubukhulu kanye nokuma, okwenza kube inselele ukunquma izinga lokushisa langaphambi kokushisa ngokomthamo.
Ukuze sihlole izinga lokushisa elifanele lokushisa izinto zokusebenza ngesikhathi senqubo yokucwilisa ngofulawa webhedi okhiqizwe ngoketshezi , sisebenzisa uhlelo lwethu lokucwilisa ngofulawa webhedi okhiqizwe ngokuzenzakalelayo oluzenzele lona futhi olukhiqizwe ngokuzenzakalelayo. Ngokuhlanganisa lokhu nokuhlangenwe nakho kwethu ekukhiqizeni imikhiqizo ehlukahlukene efana nocingo lokuhlukanisa ithrafikhi, amanethi okuvikela izindonga zengadi kanye nezakhiwo zikamasipala, amashalofu esiqandisi, amashalofu okuthenga, amanethi okuzalanisa, iziphethu, namapayipi ensimbi kusetshenziswa i-thermoplastic powder ehlukene, lokhu kuhlola kunikeza isisekelo semfundiso kanye nendlela yokwenza ngcono inqubo yokucwilisa.
Izindlela Zokuhlola
1.Ukulungiselela Isampula
Amasampula ngokuyinhloko ahlanganisa insimbi emise okwenduku, kanti amanye enziwe ngethusi ne-aluminium, anobubanzi obungu-0.8, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 12.0, 14.0, 16.0, 18.0. , 20.0
2.Thermoplastic Powder
I-LDPE i-thermoplastic powder yayisetshenziswa kakhulu ekuhlolweni, ngenkathi PVC, i-PA, nezinye izimpushana nazo zahlolwa.
3.Inqubo
Ukwelashwa kwangaphambili → ukushisa kuqala → ukucwilisa kumpushana → ukushisa kwangemuva (ukwelapha) → ukupholisa
4.Coating Quality
Amazinga okushisa ahlukene okushisa asetshenziswa ekucwiliseni amasampula okukhulunywe ngawo ngenhla kumpushana we-thermoplastic ohlukahlukene; ngemva kwezinqubo zokupholisa nokubeka izinga lokushisa eliphansi, ikhwalithi yokumboza yahlolwa futhi yarekhodwa kuThebula 1, Ithebula 2, kanye neThebula lesi-3.
Ukuhlaziywa Kwezinto Ezinomthelela
Ngokusekelwe emiphumeleni yokuhlola futhi ngokuhambisana nedatha evezwe kuThebula 1, Ithebula 2, kanye neThebula 3, ijika lahlelwa ukuze limelele inani eliphezulu lokushisa langaphambi kokushisa kwesampula ngayinye, njengoba kuboniswe esithombeni.
Imithelela ye-Thermoplastic Powder
Ijika lokushisisa le-workpiece liyahlukahluka kuma-resin empushana ahlukene, njengoba kuboniswe emfanekisweni ongenhla. Ngenxa yobubanzi obubanzi phakathi kwendawo yokuthambisa (80 – 90 ℃) nendawo yokuncibilika (105 – 130℃) ye-polyethylene. (PE), kanye nezinga lokushisa eliqhekekayo lika-300 ℃, izinga lokushisa eliphezulu lokushisa liyadingeka endaweni yokusebenza. Kuphela uma kushisiswe emazingeni okushisa angaphezu kuka-360 ℃ isikhathi eside lapho kuba khona ukuphuzi kokunamathela.
I-Polyvinyl chloride (PVC) ayinakho indawo yokuncibilika ehlukile kodwa iqala ukuthamba ku-130℃ futhi ingageleza ku-180℃. Iqala ukubola ngaphezu kuka-200℃, ikhiphe i-hydrogen chloride, intuthu, futhi ikhiphe iphunga lamakhala. Ukwenyuka kancane kwezinga lokushisa noma izikhathi zokuchayeka isikhathi eside kancane kancane kubangela ukuphuzi nokuba mnyama kwenamathela. Njengoba PVCIzinga lokushisa elincibilikayo liseduze nezinga layo lokushisa lokubola, ukulawula okuqinile phezu kwezinga lokushisa elishisayo le-workpiece liyadingeka.
Izembatho zePolyamide (PA) (imvamisa inayiloni engu-1010, inayiloni 11, inayiloni12) inephuzu lokuncibilika elisuka ku-180 kuye ku-230℃ kanye namazinga okushisa okubola angaphezu kuka-300℃; nokho, ububanzi phakathi kwamazinga okushisa abo okuncibilika nokubola buhlala buncane. Ukucwilisa inayiloni kuvame ukudinga ukupholisa ngokushesha, futhi ukulawula izinga lokushisa langaphambi kokushisa kufakazela inselele.
Ithonya Elivela Ebugqileni Bomsebenzi
Ngokombono, izinga lokushisa langaphambi kokushisa kwe-workpiece kufanele libe phezulu kancane kunezinga lokushisa elincibilikayo lempushana ukuze kube lula ukuphulukiswa kwempushana kanye nokufakwa endaweni yensimbi. Kodwa-ke, imiphumela yokuhlola ikhombisa ukuhluka okubalulekile emazingeni okushisa okushisa ngaphambi kwesikhathi kuma-workpiece anobubanzi obuhlukene nobukhulu. Lokhu kubangelwa amandla amakhulu okushisa ezinto zokusebenza eziwugqinsi, okuvimbela ukuchithwa kokushisa okuphumelelayo ngemva kokushisisa futhi kuholela ekushintsheni okuncane kwezinga lokushisa ngesikhathi sokudluliselwa kusuka kuhhavini kuya ku-powder tank. Ngakho-ke, izinga lokushisa eliphezulu lokushisa alikwazi ukusetshenziswa kuma-workpieces amakhulu; kunalokho, kufanele zishiswe emazingeni okushisa aphansi isikhathi eside. Ngakolunye uhlangothi, ama-workpiece amancane anamandla aphansi okushisa futhi ahlakaza ukushisa ngokushesha, okwenza kudingeke ukuthi kusetshenziswe “umphumela wokushaqeka oshisayo” ngokushisa okuphezulu kwangaphambi kokushisa ukuze kuncibilike inhlaka yempushana. Izinto zokusebenza ezizacile kakhulu zinomthamo omncane wokushisa futhi ngisho namazinga okushisa aphakeme kuba yinselele ukufeza ukunamathela okuphelele kokunamathela.
Ezindaweni zokusebenza ezenziwe ngezinto ezinobubanzi obuhlukahlukene noma ubukhulu, kufanele kucatshangelwe kabanzi lapho kunqunywa amazinga okushisa okushisa ngaphambi kwesikhathi - kuqinisekiswe ukuthi izinga lokushisa eliphansi liqinisekisa ukumbozwa okuphelele kokumboza ezindaweni ezincane kakhulu kuyilapho ugwema ukuphuzi ezingxenyeni ezijiyile ngokukhetha umkhawulo ophezulu ofanele.
Umthelela Wezinto Zokusebenza
Iningi lama-workpieces okuhlola okukhulunywe ngawo ngenhla enziwe ngensimbi ephansi ye-carbon. Ezinhlotsheni ezahlukene zensimbi, kungakhathaliseki ukuthi i-carbon steel noma i-alloy steel, izinga lokushisa langaphambi kokushisa linomthelela omncane. Izinga lokushisa langaphambi kokushisa lethusi lifana nelensimbi kodwa liphakeme kancane. I-Aluminiyamu inokushintshwa kokushisa okusheshayo kanye nokulahla, ngakho-ke izinga lokushisa langaphambi kokushisa kufanele libe phezulu.
Umthelela Womumo Womsebenzi
Ukuhlolwa kuphinde kwenziwa ezintweni zokusebenza ezinomumo ohlukahlukene, okuveza ukuthi izingxenye eziqinile zibonisa isitoreji esinensayo sokushisa kanye namazinga okulahleka, kuyilapho izingxenye ezingenalutho ezivaliwe njengezingxenye zamashubhu nazo zibonisa ukuncishiswa kokushisa. Ngokuphambene, izingxenye zemeshi nezizacile zithola ukulahlekelwa ukushisa okusheshayo. Izinga lokugcinwa kokushisa nokuchithwa linqunywa ngokuyinhloko isilinganiso sendawo yevolumu ukuya phezulu kwendawo yokusebenza. Ngakho-ke, kuyadingeka ukulungisa izinga lokushisa langaphambi kokushisa ngokusekelwe ku-coefficient efanelekile ehambisana nokuma kwe-workpiece. Kudingeka olunye ucwaningo kule ndawo.
Isiphetho
- Izinga lokushisa langaphambi kokushisa kwe-workpiece liyisici esibucayi kakhulu ekunqumeni ikhwalithi yokumboza ngesikhathi sokucwiliswa kombhede owenziwe ngamanzi.
- Izinga lokushisa langaphambi kokushisa kwe-workpiece linqunywa ngokuyinhloko ububanzi noma ubukhulu bayo, futhi linganqunywa ngokubhekisela kuMfanekiso 1 ukuze uthole isiqondiso.
- Ama-resin e-powder ahlukene anamaphuzu ahlukene okuncibilika kanye namaphuzu okubola, okufanele acatshangelwe ngokugcwele lapho kunqunywa inqubo yokucwilisa.
- Izinto kanye nokuma kwe-workpiece nakho kuthonya izinga lokushisa lokushisa elidingekayo, elinganxeshezelwa kusetshenziswa isici sokulungisa.
