Kuchuluka kwa ntchito
Oyenera mankhwala odana ndi dzimbiri mbali yamkati ya chitoliro.Type I ndi oyenera mankhwala odana dzimbiri pamwamba kukhudzana mwachindunji ndi chitoliro mpweya, ndi kutentha kukana malire 250 ℃ ndi sulfuric acid dzimbiri kukana malire ndende ya 40%.
Malangizo Ogwiritsira Ntchito
Chithandizo cha Substrate ndi Surface
1, zitsulo gawo lapansi mankhwala: sandblasting kapena kuwombera kuphulika kuchotsa dzimbiri kwa mlingo Sa2.5, roughness 40 ~ 70um, kumapangitsanso adhesion wa ❖ kuyanika ndi gawo lapansi.
2, Mukamagwiritsa ntchito, yambitsani chigawo A choyamba, kenaka onjezerani kuchiritsa chigawo B molingana, yambitsani mofanana, sungani nthawi yophunzitsira 15 ~ 30 mphindi, sinthani kukhuthala kwa ntchito ndikuchuluka koyenera kwawochepa thupi mwapadera malinga ndi njira zogwiritsira ntchito.
Njira zogwiritsira ntchito
1, kupopera opanda mpweya, kupopera mpweya kapena roller
Kupaka burashi ndi zodzigudubuza zimangovomerezedwa kuti azivala mizere, zokutira zazing'ono kapena kukhudza.
2, Analimbikitsa youma filimu makulidwe: 300um, wosanjikiza limodzi ❖ kuyanika ndi za 100um.
3, Popeza kuti malo owononga ndi owopsa, ndipo kusowa kwa zokutira kumapangitsa kuti chitsulo chiwonongeke msanga, kuchepetsa moyo wautumiki.
chifukwa cha kugwiritsira ntchito malo owononga a filimu yophimba kukhala yolimba kwambiri, kutayikira kumapangitsa kuti chophimbacho chiwonongeke mwamsanga ndikuchepetsa moyo wautumiki.
Desulfurization & denitrification chipangizo mkati khoma ntchito malangizo
Chithandizo chapamwamba
Mafuta kapena mafuta amayenera kuchotsedwa malinga ndi muyezo wa SSPC-SP-1 zosungunulira.
Ndi bwino kupopera mankhwala zitsulo pamwamba Sa21/2 (ISO8501-1: 2007) kapena SSPC-SP10 muyezo.
Ngati makutidwe ndi okosijeni amapezeka pamtunda pambuyo popopera mankhwala komanso musanapente mankhwalawa, ndiye kuti pamwamba pake iyenera kuponyedwanso.Gwirizanani ndi zowonera zomwe zafotokozedwa.Zowonongeka zapamtunda zomwe zimawonekera panthawi yopopera mankhwala ziyenera kupakidwa mchenga, kudzazidwa, kapena kuthandizidwa moyenera.Kukula kwapamwamba kovomerezeka ndi 40 mpaka 70μm.Magawo omwe amathiridwa ndi mchenga kapena kuwomberedwa amayenera kuchitidwa mkati mwa maola anayi.
Ngati gawo lapansi silinasankhidwe pamlingo wofunikira, zingayambitse dzimbiri, kuphulika kwa filimu ya utoto, kuwonongeka kwa filimu ya utoto pakumanga, ndi zina zambiri.
Malangizo ogwiritsira ntchito
Kusakaniza: Zogulitsazo zimayikidwa ndi zigawo ziwiri, Gulu A ndi Gulu B. Chiŵerengerocho chikugwirizana ndi ndondomeko ya mankhwala kapena chizindikiro pa mbiya yonyamula.Sakanizani gawo la A bwino ndi chosakaniza mphamvu kaye, kenaka yikani gawo la B molingana ndikugwedeza bwino.Onjezani kuchuluka koyenera kwa epoxy thinner, dilution ratio ya 5 ~ 20%.
Pambuyo posakanizidwa ndi kusonkhezera bwino, mulole kuti ikhwime kwa mphindi 10-20 musanagwiritse ntchito.Nthawi yokhwima ndi nthawi yoyenera idzafupikitsidwa pamene kutentha kumakwera.Utoto wokonzedwa uyenera kugwiritsidwa ntchito mkati mwa nthawi yovomerezeka.Utoto womwe umaposa nthawi yoyenera uyenera kutayidwa ndi zinyalala ndipo usagwiritsidwenso ntchito.

Njira zogwiritsira ntchito
Kupopera mbewu popanda mpweya kumalimbikitsidwa pomanga malo akuluakulu, kupopera mpweya, brushing kapena zokutira zogudubuza zingagwiritsidwenso ntchito.Ngati kupopera mbewu mankhwalawa, ma weld seams ndi ngodya ziyenera kupakidwa penti kaye, apo ayi, pentiyo imatha kunyowetsa bwino penti, kutayikira, kapena filimu yopyapyala ya utoto, zomwe zimapangitsa dzimbiri ndi kusenda kwa filimuyo.
Imani kaye pakugwira ntchito: Osasiya utoto m'machubu, mfuti, kapena zida zopoperapo mankhwala.Yatsani zida zonse bwino ndi zoonda.Utotowo sayenera kusindikizidwanso mutatha kusakaniza.Ngati ntchitoyo yayimitsidwa kwa nthawi yayitali, tikulimbikitsidwa kugwiritsa ntchito utoto wosakanizidwa mwatsopano poyambitsanso ntchitoyo.
Kusamalitsa
Izi ndi anti- dzimbiri ❖ kuyanika kwa khoma lamkati la desulfurization ndi denitrification chipangizo, pansi pamwamba ndi mtundu umodzi, ndi mkulu abrasion kukana, zabwino asidi kukana (40% sulfuric acid), ndi kusintha kutentha kukana.Pomanga, mfuti yopopera, ndowa ya penti, burashi, ndi roller siziyenera kusakanikirana, ndipo zinthu zopentedwa ndi mankhwalawa zisaipitsidwe ndi utoto wina wamba.
Kuyang'ana filimu yokutira
a.Burashi, mpukutu, kapena kupopera mbewu mankhwalawa ayenera kuphatidwa mofanana, popanda kutayikira.
b.Kuwona makulidwe: pambuyo pa wosanjikiza uliwonse wa utoto, yang'anani makulidwe ake, pambuyo pake utoto uyenera kuyang'ana makulidwe onse a filimu ya utoto, kuyeza mfundo za 15 masikweya mita, 90% (kapena 80%) ya mfundo zoyezera zimafunika. kufika pamtengo wamtengo wapatali wotchulidwa, ndipo makulidwe omwe safika pamtengo wotchulidwawo siyenera kukhala wotsika kuposa 90% (kapena 80%) wa mtengo womwe watchulidwa, apo ayi utoto uyenera kupentanso.
c.Makulidwe onse a zokutira ndi kuchuluka kwa njira zokutira ziyenera kukwaniritsa zofunikira pakupanga;pamwamba ayenera kukhala yosalala ndi opanda zizindikiro, zogwirizana mu mtundu, popanda pinholes, thovu, kuyenderera pansi, ndi kusweka.
d.Kuyang'anira maonekedwe: Pambuyo popanga utoto uliwonse, mawonekedwe ake ayenera kuyang'aniridwa, kuyang'ana ndi maso kapena magalasi okulirapo ka 5, ndipo ming'alu, ming'alu, kupukuta, ndi kutayikira kwa utoto ziyenera kukonzedwa kapena kupakidwanso, ndikupachikidwa pang'ono. kuloledwa kukhalapo.Zofunikira zenizeni za mtundu wa zokutira ndi izi:
| Zinthu zoyendera | Zofunikira zamtundu | Njira zoyendera |
| Kupukuta, kutuluka kwa burashi, dzimbiri la poto, ndi kulowa pansi | Zosaloledwa | Kuyang'ana m'maso |
| Pinhole | Zosaloledwa | 5 ~ 10x kukula |
| Khungu loyenda, lamakwinya | Zosaloledwa | Kuyang'ana m'maso |
| Kuyanika filimu makulidwe | Osachepera kapangidwe makulidwe | Magnetic Makulidwe Gauges |
Mikhalidwe yofunsira ndi zoletsa
Kutentha kozungulira ndi gawo lapansi:5-40 ℃;
Zomwe zili mumadzi a substrate:<4% <br/> ndiChinyezi cha mpweya choyenera:Chinyezi chocheperako mpaka 80%, mvula, chifunga, ndi chipale chofewa sichingamangidwe.
Dew point:Kutentha kwapamtunda kwa gawo lapansi ndi kupitirira 3 ℃ pamwamba pa mame.
Ngati itamangidwa pamalo osagwirizana ndi momwe amamangira, zokutirazo zimakhazikika ndikupangitsa filimu ya penti kuphuka, matuza, ndi zolakwika zina.
Mankhwalawa sagonjetsedwa ndi kuwala kwa ultraviolet, choncho akulimbikitsidwa kuti azikhala m'nyumba.
Chitetezo
Izi ziyenera kugwiritsidwa ntchito pamalo opangira ndi akatswiri opaka utoto pansi pa bukhuli la malangizo, pepala lachitetezo chazinthu, ndi malangizo omwe ali pachotengera.Ngati Material Safety Data Sheet (MSDS) sanawerengedwe;mankhwalawa sayenera kugwiritsidwa ntchito.
Kupaka konse ndi kugwiritsa ntchito mankhwalawa kuyenera kuchitidwa pansi pazaumoyo wadziko lonse, chitetezo, ndi miyezo ndi malamulo azachilengedwe.
Ngati kuwotcherera kapena kudula kwa lawi kuyenera kuchitidwa pazitsulo zokutidwa ndi mankhwalawa, fumbi lidzatulutsidwa, choncho zida zoyenera zodzitetezera ndi mpweya wokwanira wochotsa m'deralo zimafunika.
Kusungirako
Itha kusungidwa kwa miyezi 12 pa kutentha kwa 25°C.
Pambuyo pake iyenera kufufuzidwanso musanagwiritse ntchito.Sungani pamalo ouma, amthunzi, kutali ndi kutentha ndi magwero a moto.
Chidziwitso
Zomwe zaperekedwa m'bukhuli zachokera ku labotale yathu komanso zomwe takumana nazo ndipo cholinga chake ndi monga chofotokozera makasitomala athu.Popeza mikhalidwe yogwiritsira ntchito mankhwalawa ndi yomwe sitingathe kuilamulira, timangopereka chitsimikizo cha ubwino wa mankhwalawo.
