Yankho Lochotsa Zinyalala la PD
Kugwiritsa Ntchito Njira Yochotsera Zinyalala za PD
Zosungunulira zamoyo zomwe zimapangidwa mumakampani opanga ma semiconductor zimayengedwa ndikubwezeretsedwanso pansi pa njira yofananira kudzera mu chipangizo chowongolera kuti apange zinthu monga stripping liquid B6-1, stripping liquid C01, ndi stripping liquid P01. Zinthuzi zimagwiritsidwa ntchito makamaka popanga ma panel owonetsera ma crystal amadzimadzi, ma semiconductor integrated circuits ndi njira zina.
Ukadaulo Wokwanira Wotaya Zinyalala wa Gaoke Wopanda Zoopsa
Kuyambitsidwa kwa ukadaulo wapamwamba kwambiri wobwezeretsa zinyalala za organic solvent padziko lonse lapansi komanso njira yosungira mphamvu yogwiritsira ntchito bwino kwambiri kumathandiza kampaniyo kukhala ndi nsanja yotulutsira zinyalala yokhala ndi ukadaulo wapamwamba wakunyumba, kukonza kwakukulu komanso kulondola kwambiri pakukonza; nthawi zonse imagaya ndi kuyamwa makampani akunyumba ndi akunja monga Desan Company yaku South Korea. Kuphatikiza pa ukadaulo wobwezeretsa zinyalala za organic solvent, kudzera mu zaka zambiri zopititsa patsogolo njira ndi kusintha kwaukadaulo, kampani yathu yapezanso ukadaulo wotsogola wopanga zinthu mdziko muno komanso mulingo wogwirira ntchito, ndipo yadzaza kusiyana kwa kubwezeretsa zinyalala za organic ndikugwiritsanso ntchito m'chigawo chathu komanso ngakhale kumpoto chakumadzulo. Malo Oyera.
1. Chogulitsachi chili ndi chiyero chachikulu. Kuyera kwa chinthu chosungunuka cha organic choyeretsedwa kumatha kufika pamlingo wapamwamba kwambiri padziko lonse lapansi (ppb level, 10-9) kuyera > 99.99%. Chingagwiritsidwe ntchito mwachindunji m'mapanelo a LCD, mabatire a lithiamu-ion, ndi zina zotero. mukatha kuchikonza.
2. Kapangidwe kake ndi kapadera ndipo makina ake ndi othandiza kwambiri komanso amasunga mphamvu. Palibe chifukwa chogwiritsa ntchito ma reflux angapo panthawi yothira. Zigawo zosiyanasiyana zimatha kulekanitsidwa ndikuyeretsedwa mu nsanja. Imatha kusunga mphamvu zoposa 60% poyerekeza ndi makina ena.
3. Zipangizozi zimatha kusinthasintha kwambiri. Popanga zowonjezera zofanana za mitundu yosiyanasiyana ya zosungunulira zinyalala, choyamba zimakonzedwa kale kenako zimayikidwa mu nsanja yosungunulira zinyalala kuti zisungunulirane. Zingathe kumaliza kubwezeretsanso ndikugwiritsanso ntchito mitundu yoposa 25 ya zosungunulira zinyalala.
4. Pakadali pano, ili ndi magulu atatu a makina opangira ma distillation tower, ndipo mphamvu yopanga ndi kugwiritsanso ntchito zinyalala za organic solvents ndi matani 30,000 pachaka. Pakati pawo, nsanja ya I# distillation ndi nsanja yopitilira yokhala ndi kutalika kwa mamita 43. Imadziwika ndi kudyetsa kosalekeza komanso kutulutsa zinthu kosalekeza. Imatha kupanga ndikubwezeretsanso zinyalala zambiri za organic solvents. Yagwiritsidwa ntchito ndi Chongqing Huike Jinyu Electronics Company, Xianyang Rainbow Optoelectronics Company, ndi zina zotero. Makasitomala amabwezeretsanso ndikugwiritsanso ntchito zinthu zamagetsi zochotsera zinyalala ndipo apambana mayeso ogwiritsira ntchito makasitomala; nsanja za II# ndi III# distillation ndi nsanja zazikulu zokhala ndi kutalika kwa mamita 35. Zimadziwika ndi kuthekera kokonza magulu ang'onoang'ono komanso okhala ndi matope ambiri. Madzi otayira a organic abwezeretsedwanso ndikugwiritsidwanso ntchito ngati zinthu zamagetsi zochotsera zinyalala kwa makasitomala monga Chengdu Panda Electronics Company ndi Ordos BOE Electronics Company, ndipo yadziwika kwambiri ndi makasitomala.
5. Ili ndi zipinda zoyera, ICP-MS, ma tinthu tating'onoting'ono ndi zida zina zowunikira komanso zida zodzaza, zomwe sizingotsimikizira kuti zosungunulira za organic zibwezeretsedwanso kuti zipange zosungunulira za organic zamagetsi, komanso zimaonetsetsa kuti zinthu zamafakitale zikukonzedwanso bwino, kupatsa makasitomala zinthu zapamwamba kwambiri. Zosungunulira za organic zamagetsi zamagetsi.
