Abakhiqizi abaningi benjoloba ye-nitrile butadiene (NBR) bahlushwa yizinkinga ezinzima zokuhlanzwa kwe-nitrile. Ukucheba ngesandla kancane kancane kwehluleka ukuhlangabezana nezidingo zamandla okukhiqiza, futhi ama-burrs amancane ezingxenyeni ezinembile awakwazi ukususwa ngokuphelele, okuye kwaba yisithiyo esibalulekile sokuvimbela inzuzo ye-oda. I-STMC (i-Nanjing Zhaoling Precision) ibilokhu igxile ekuhlanzweni kwe-nitrile amashumi eminyaka. Ubuchwepheshe bayo obukhethekile bokuhlanzwa kwe-nitrile ewuketshezi buxazulula ngempumelelo izindawo ezibuhlungu zezimboni ngokusebenza kahle okuphezulu kanye nokunemba okuphezulu, kusiza abakhiqizi abaningi benjoloba ukuxazulula izinselele zokuhlanzwa kwe-nitrile ngokuphelele.
Kungani Amafektri e-NBR Ebhajwa Enkingeni Ngokudilizwa Kwempahla
I-NBR inokuguquguquka okuphezulu kanye nokuqina, okuholela kuma-burrs anamathele ngokuqinile emigqeni yokuhlukana, imigodi kanye nemigodi. Izindlela ezivamile zokususa ukungcola zinezinkinga ezisobala: Ngokuphathelene nokusebenza kahle kokukhiqiza, ukusika ngesandla kudinga umsebenzi omkhulu ngokukhipha okulinganiselwe kwansuku zonke, okubangela ukubambezeleka kokulethwa njalo kwama-oda amaningi. Ukusika i-blade yomshini kuholela kalula ekunamatheleni kwezinto ezibonakalayo kanye nokuvaleka komshini; ama-burrs afihliwe adinga ukulungiswa kabusha kwesibili futhi andise imijikelezo yokukhiqiza. Ngokuphathelene nokunemba kokucubungula, amandla okusika ngesandla angaguquki avame ukuholela emikhiqizweni enqatshiwe evela kuma-burrs asikiwe ngokweqile noma asele. Ukushisa okuphezulu okukhiqizwa ngesikhathi sokupholisha konakalisa ukusebenza kokuvala kwezingxenye ze-NBR ngokukhiqiza komkhiqizo oqediwe okungazinzile, kwehluleka amazinga okuhlola ikhwalithi aqinile enkampanini yokunemba kwezimoto.
I-Liquid Nitrogen Cryogenic Deflashing: Isixazululo Sokususa I-NBR Engasebenzi Kahle Futhi Enembile Kakhulu
Ngokusekelwe esimisweni sokushisa esiphansi kakhulu se-nitrogen ewuketshezi engu--196°C, i-cryogenic deflashing isusa ama-burrs ngokusebenzisa i-brittlement ebandayo. Isebenzisa ngokugcwele izikhathi ezahlukene ze-brittlement ebandayo phakathi kwe-substrate ye-NBR eningi kanye ne-flash encane ngenxa yokwehluka kobukhulu ukuze kufezwe ukusika ngokunemba okungenamonakalo futhi kuguqulwe amasu endabuko okususa ama-deflashing: Ama-workpiece avalwa ngaphakathi kwegumbi lemishini futhi apholiswa ngokushesha ku--80℃ ~ -140℃ yi-nitrogen ewuketshezi. I-flash encane kakhulu esukela ku-0.01mm kuya ku-0.2mm iphenduka i-brittle ngaphansi kokushisa okuphansi kuyilapho isisekelo se-NBR esijiyile sigcina ukuqina kokuqala kanye nezakhiwo zomzimba. Ama-pellet e-nylon enziwe ngokukhethekile abese eqhunyiswa ngesivinini esikhulu ukuze aqhekeze futhi asuse i-brittle flash. Imfucumfucu ye-burr esele iqoqwa phakathi nendawo ngohlelo lokuhlunga olunengcindezi engemihle ngaphandle kokuklwebha noma ukulimaza imizimba yezingxenye.
Ukusebenza Kahle Kokukhiqiza Okuthuthukisiwe
1. Ukucubungula ngokuzenzakalelayo kwe-batch:
I-STMC yakha ngokuzimela imishini yokuhlanza i-Jishe series cryogenic deflashing cryogenic decay machines inqubo yemikhiqizo ye-NBR engu-20~50kg ngebhetshi ngayinye zingakapheli imizuzu eyi-10~15. Umshini owodwa ulingana nomkhiqizo wabasebenzi abanekhono abangu-6~12. Abasebenzi bangaphatha amayunithi angu-2~3 ngokulawula okuzenzakalelayo kwe-PLC, banciphise izindleko zabasebenzi ngaphezu kuka-70%.
2. Ukuhambisana okugcwele nokungasebenzi kabusha okungekho:
Le mishini isusa ngokuphelele ama-burrs afihliwe ngaphakathi kwezimbobo, izikhala kanye nezimbobo ezingaboni ze-O-rings, izivalo zikawoyela ezimise okwehlukile kanye nezingxenye ze-NBR ezisele zodonga oluncane ngesikhathi esisodwa, isusa ukusika ngesandla okwengeziwe. Ukukhiqiza ngemuva kokucubungula kukhuphuka izikhathi ezingu-3-5 ukusekela ama-oda amakhulu avela kumakhasimende ezimoto nakwamanye amazwe.
3. Isakhiwo sokonga isikhala:
Umshini ngamunye uthatha indawo engaphansi kwamamitha-skwele ayi-10, uthatha indawo yamamitha-skwele amaningi emigqa yokuhlanganisa ngesandla futhi ukhulula isikhala sendawo yokusebenzela yokwandisa umthamo wokwenza i-vulcanization.
Imishini Esezingeni Elifanele Enokunemba Okuphezulu
1. Ukunemba kokusika kwezinga le-Micron:
Ukulawulwa kokushisa okunembile kuvala izinga lokushisa elibucayi le-NBR ukuze kuhlanzwe i-micro flash encane njengo-0.01mm. Ukubekezelelana kobukhulu obuqediwe kulawulwa ngaphakathi kuka-0.03mm ngaphandle kwama-burrs asele noma umonakalo onqunyiwe kakhulu. Isivuno somkhiqizo sikhuphuka sisuka ku-75% ngaphansi kokucubungula okuvamile siye ngaphezu kuka-99.2%, okuhambisana nezidingo zokufinyelela zamandla amasha kanye nezimboni zezingxenye eziqondile ngokuzenzakalela.
2. Ikhwalithi ye-batch ehambisanayo:
Amapharamitha emishini ehleliwe agciniwe aqinisekisa ukucutshungulwa okufanayoimikhiqizo ye-NBR efanayo, isusa ukungazinzi okubangelwa ukusebenza ngesandla futhi iqinisekise ukubukeka okufanayo kanye nobukhulu kuzo zonke izinhlobo ukuze kudlule ukuhlolwa kwekhwalithi engenayo kwabathengi abangaphansi komfula.
3. Ukusebenza kwerabha kokuqala okugciniwe:
Akukho ukushisa okungqubuzanayo okukhiqizwa ekucutshungulweni kwezinga lokushisa eliphansi, okuvikela ukuqina kwe-NBR kanye nokumelana namafutha ngaphandle kokuguga komphetho, ngaleyo ndlela kuqinisekisa impilo yenkonzo yokuvala isikhathi eside yezimpahla eziqediwe.
I-STMC: Uchwepheshe Weminyaka Engamashumi Amabili Ekuhlanzeni Okuyi-Cryogenic Kwenziwe Ngokwezifiso Kwe-NBR
I-STMC izinikela ku-R&D yemishini yokususa i-nitrogen ewuketshezi futhi ithuthukisa imishini namasu enzelwe wena ahambisana nezici zezinto ze-NBR zezivalo zikawoyela, ama-O-rings kanye nezingxenye zerabha ezingavamile. Ukuhlolwa kwamasampula kwamahhala kuyatholakala, kanye nezinsizakalo ze-spectrum ezigcwele okuhlanganisa isiqondiso sokukhetha imishini, ukuqaliswa kokusebenza endaweni kanye nokusekelwa kwangemva kokuthengisa ubusuku nemini. Imishini evalwe ngokuphelele ihlangabezana nezindinganiso zokuhlola imvelo. Le nkampani isize abakhiqizi berabha ezweni lonke ekuguqulweni kobuchwepheshe kwezinqubo zokususa i-nitrogen ukuze kuncishiswe izindleko zokucubungula eziphezulu futhi kuthuthukiswe ikhwalithi yomkhiqizo ngokuyisisekelo.
Ulwazi Lokuxhumana Lokubhuka Kwamahhala Kwesampula Nokubuza Okuningiliziwe
