Opanga ambiri a nitrile butadiene rabara (NBR) amakumana ndi mavuto ovuta okhudza kuyeretsa mpweya. Kuchekerera pang'onopang'ono kwa manja sikukwaniritsa zofunikira pakupanga, ndipo ma burrs ang'onoang'ono pazigawo zolondola sangathe kuchotsedwa bwino, zomwe zakhala vuto lalikulu loletsa phindu la dongosolo. STMC (Nanjing Zhaoling Precision) yakhala ikuyang'ana kwambiri pa kuyeretsa mpweya kwa cryogenic kwa zaka zambiri. Ukadaulo wake wapadera wamadzimadzi a nayitrogeni cryogenic deflashing umathetsa bwino mavuto a mafakitale ndi luso lapamwamba komanso kulondola kwambiri, kuthandiza opanga ambiri a rabara kuthetsa mavuto a kuyeretsa mpweya kwathunthu.
Chifukwa Chake Mafakitale a NBR Ali Pamavuto Chifukwa cha Kuchotsa Madzi Oipa
NBR ili ndi kusinthasintha kwakukulu komanso kusinthasintha, zomwe zimapangitsa kuti ma burrs azigwira ntchito mwamphamvu pamizere yolekanitsa, mabowo ndi mipata. Njira zachikhalidwe zochotsera ma flashing zili ndi zovuta zoonekeratu: Ponena za magwiridwe antchito, kudula ndi manja kumafuna ntchito yayikulu yokhala ndi ntchito yochepa tsiku lililonse, zomwe zimapangitsa kuti kutumiza kuchedwe pafupipafupi kwa maoda ambiri. Kudula tsamba la makina kumabweretsa kukanikiza zinthu mosavuta komanso kutsekeka kwa makina; ma burrs obisika amafuna kukonzanso kwina ndikuwonjezera nthawi yopangira. Ponena za kulondola kwa kukonza, mphamvu yosasinthasintha yodulira ndi manja nthawi zambiri imabweretsa zinthu zokanidwa kuchokera ku ma burrs odulidwa kwambiri kapena otsala. Kutentha kwambiri komwe kumachitika panthawi yopukuta kumawononga magwiridwe antchito otseka a zigawo za NBR ndi kupangika kosakhazikika kwa chinthu chomalizidwa, kulephera miyezo yowunikira bwino ya gawo lolondola la magalimoto.
Kuchotsa Madzi a Nayitrogeni Cryogenic: Zonse mu imodzi Njira Yothetsera Mavuto a NBR Yogwira Ntchito Mwapamwamba komanso Yolondola Kwambiri
Kutengera ndi mfundo yotsika kwambiri ya kutentha ya -196°C ya nayitrogeni yamadzimadzi, kuyeretsa kwa cryogenic kumachotsa ma burrs kudzera mu kuzizira. Kumagwiritsa ntchito mokwanira nthawi zosiyanasiyana zozizira pakati pa substrate ya bulk NBR ndi kunyezimira kochepa chifukwa cha kusiyana kwa makulidwe kuti zitheke kudula molondola popanda kuwonongeka ndikusintha njira zachikhalidwe zochotsera ma burrs: Ma workpiece amatsekedwa mkati mwa chipinda cha zida ndikuzizira mofulumira mpaka -80℃ ~ -140℃ ndi nayitrogeni yamadzimadzi. Kunyezimira kopyapyala kwambiri kuyambira 0.01mm mpaka 0.2mm kumasanduka kusweka pansi pa kutentha kochepa pomwe maziko a NBR okhuthala amakhalabe ndi kusinthasintha koyambirira komanso mawonekedwe enieni. Ma pellets a nayiloni opangidwa mwapadera amaphwanyidwa mwachangu kuti asweke ndikuchotsa kunyezimira kosweka. Zinyalala zotsalira za burr zimasonkhanitsidwa pakati kudzera mu makina osefera opanda kupsinjika popanda kukanda kapena kuwononga ziwalo za zigawo.
Kupititsa patsogolo Kuchita Bwino kwa Ntchito
1. Kukonza gulu lokha:
STMC idapanga makina oyeretsera madzi a Jishe series cryogenic deflashing machines processing 20~50kg NBR products pa batch mkati mwa mphindi 10~15. Makina amodzi amafanana ndi zotsatira za ogwira ntchito 6~12 odziwa bwino ntchito zamanja. Ogwiritsa ntchito amatha kuyang'anira mayunitsi 2~3 pogwiritsa ntchito PLC control yodziyimira yokha, kuchepetsa ndalama zogwirira ntchito ndi zoposa 70%.
2. Kugwirizana kwathunthu ndi kusintha konse:
Zipangizozi zimachotsa bwino ma burrs obisika mkati mwa mabowo, mipata ndi mabowo osawoneka a ma O-rings, zomatira zamafuta zooneka ngati mawonekedwe apadera ndi zida zosinthira za NBR zopyapyala nthawi imodzi, ndikuchotsa kudula kowonjezera pamanja. Kugwira ntchito bwino pambuyo pokonza kumawonjezeka nthawi 3-5 kuti kuthandizire maoda ambiri ochokera kwa makasitomala a magalimoto ndi akunja.
3. Kapangidwe kosungira malo:
Makina aliwonse amakhala ndi malo osakwana masikweya mita 10, m'malo mwa masikweya mita ambiri a mizere yolumikizirana ndi manja ndikumasula malo ogwirira ntchito kuti awonjezere mphamvu ya vulcanization.
Makina Opangidwa Mwaluso Kwambiri Okhazikika
1. Kulondola kodulira kwa micron:
Kuwongolera kutentha kolondola kumatseka kutentha kofunikira kwa NBR kuti kuchotse micro flash yopyapyala ngati 0.01mm. Kulekerera kwa miyeso yomalizidwa kumayendetsedwa mkati mwa 0.03mm popanda ma burrs otsala kapena kuwonongeka kodula kwambiri. Kuchuluka kwa zinthu kumakwera kuchoka pa 75% pansi pa kukonza kwachikhalidwe mpaka kupitirira 99.2%, mogwirizana ndi zofunikira zopezera mphamvu zatsopano ndi mafakitale olondola a magalimoto.
2. Ubwino wa batch wogwirizana:
Magawo a zida zosungidwa zosungidwa amatsimikizira kukonzedwa kofanana kwaKukonza zinthu za NBR zomwe zimafanana ndi zomwezo, kuchotsa kusakhazikika komwe kumachitika chifukwa cha kugwiritsa ntchito pamanja ndikuwonetsetsa kuti mawonekedwe ndi kukula kwake zikugwirizana m'magulu onse kuti zitsimikizire kuwunika kwabwino kwa ogula omwe ali pansi pa mtsinje.
3. Kugwira ntchito koyambirira kwa rabara kosungidwa:
Palibe kutentha kokangana komwe kumapangidwa pokonza kutentha kochepa, kuteteza kusinthasintha kwachilengedwe kwa NBR ndi kukana mafuta popanda kukalamba, motero kumateteza nthawi yayitali yogwirira ntchito yotseka zinthu zomalizidwa.
STMC: Katswiri wa zaka makumi awiri mu Cryogenic Deflashing Yopangidwira NBR
STMC imadzipereka ku kafukufuku ndi chitukuko cha zida zochotsera nayitrogeni yamadzimadzi ndikupanga makina ndi njira zopangidwira anthu oyenerera zomwe zimagwirizana ndi mawonekedwe a zinthu za NBR za zisindikizo zamafuta, mphete za O ndi zida za rabara zosakhazikika. Kuyesa kwa zitsanzo kwaulere kulipo, pamodzi ndi ntchito zonse kuphatikiza malangizo osankha zida, kuyimitsa ntchito pamalopo komanso chithandizo cha maola onse pambuyo pogulitsa. Makina otsekedwa mokwanira amakwaniritsa miyezo yowunikira chilengedwe. Kampaniyo yathandiza opanga rabala mdziko lonse kusintha njira zochotsera madzi kuti achepetse ndalama zambiri zogwirira ntchito ndikukweza mtundu wa zinthu.
Zambiri Zolumikizirana Kuti Mupeze Chitsanzo Chaulere Chosungitsira ndi Kufunsa Mwatsatanetsatane
