Ndi kulengeza ndi kukhazikitsidwa kwa malamulo okhwimitsa kwambiri azachilengedwe m'dziko, zofunika pakumanga zojambula zamagalimoto zikuchulukirachulukira.Kupenta sikuyenera kuwonetsetsa kuti ntchito yabwino yolimbana ndi dzimbiri, kukongoletsa kwapamwamba, ndi zomangamanga zapamwamba, komanso kutengera zida ndi njira zogwirira ntchito bwino ndikuchepetsa kutulutsa kwamafuta osakhazikika (VOC).Utoto wopangidwa ndi madzi pang'onopang'ono umakhala chinthu chofunikira kwambirizokutirachifukwa cha zigawo zawo zachilengedwe.
Utoto wokhala ndi madzi umatha kupititsa patsogolo ntchito yokonza bwino, komanso kukhala ndi mphamvu zophimba zolimba, zomwe zingachepetse kuchuluka kwa kupopera mankhwala ndi kuchuluka kwa utoto wogwiritsidwa ntchito, komanso kuchepetsa nthawi yopopera mankhwala ndi kupopera mbewu mankhwalawa.
Kusiyana pakati pa utoto wamadzi ndi mafuta
1. Zothandizira zosiyanasiyana zochepetsera
The diluting wothandizira madzi utoto utoto ndi madzi, amene ayenera kuwonjezeredwa pa ziŵerengero zosiyanasiyana kuchokera 0 mpaka 100% malinga ndi kufunikira, ndi diluting wothandizila utoto mafuta - zosungunulira organic.
2. Ntchito zosiyanasiyana zachilengedwe
Madzi, omwe amasungunula utoto wopangidwa ndi madzi, alibe benzene, toluene, xylene, formaldehyde, TDI toxic heavy metals ndi zinthu zina zowopsa za carcinogenic, choncho ndi otetezeka ku thanzi la munthu.
Madzi a nthochi, xylene ndi mankhwala ena nthawi zambiri amagwiritsidwa ntchito ngati mankhwala ochotsera utoto wamafuta, omwe amakhala ndi benzene ndi ma carcinogens ena owopsa.
3. Ntchito zosiyanasiyana
Utoto wokhala ndi madzisikuti zimangoipitsa chilengedwe, komanso zimakhala ndi filimu yochuluka ya utoto, yomwe imakhala yowoneka bwino kwambiri pambuyo pochita zinthu pamwamba pa chinthucho ndipo imakhala ndi kusinthasintha kwakukulu komanso kukana madzi, abrasion, ukalamba ndi chikasu.
Makhalidwe aukadaulo a kupopera utoto utoto wamadzi
Kutentha kwa madzi mu utoto wopangidwa ndi madzi kumayendetsedwa makamaka ndi kusintha kutentha ndi chinyezi cha chipinda chopoperapo mankhwala, ndi zolimba zokutira nthawi zambiri zimakhala 20% -30%, pamene zopaka za utoto wosungunulira zimafika 60% -70%, kotero kusalala kwa utoto wamadzi ndi bwino.Komabe, iyenera kutenthedwa ndikuwumitsidwa, apo ayi n'zosavuta kukhala ndi mavuto apamwamba monga kupachika ndi thovu.
1. Makhalidwe aukadaulo a zida
Choyamba, kuwononga kwamadzi kumakhala kwakukulu kuposa zosungunulira, kotero njira yoyendetsera madzi yozungulira m'chipinda chopoperapo mankhwala iyenera kupangidwa ndi chitsulo chosapanga dzimbiri;chachiwiri, mpweya wa m'chipinda chopoperapo mankhwala uyenera kukhala wabwino, ndipo liwiro la mphepo liyenera kuyendetsedwa pakati pa 0.2 ~ 0.6m / s.
Kapena kuchuluka kwa mpweya kumafikira 28,000m3 / h, yomwe imatha kukumana muchipinda chopaka utoto wamba.Ndipo chipinda chowumitsa chifukwa cha chinyezi chambiri m'mlengalenga chidzachititsanso zowonongeka kwa zipangizo, kotero khoma la chipinda chowumitsa liyeneranso kupangidwa ndi zinthu zotsutsana ndi zowonongeka.
2. Makina opaka utoto wopopera
Kutentha koyenera kwa chipinda chopoperapo mankhwala opopera utoto wopangidwa ndi madzi ndi 20 ~ 26 ℃, ndi chinyezi chabwino kwambiri ndi 60 ~ 75%.Kutentha kovomerezeka ndi 20 ~ 32 ℃, ndi chinyezi chovomerezeka ndi 50 ~ 80%.
Choncho, payenera kukhala zipangizo zoyenera kutentha ndi chinyezi m'chipinda chopoperapo mankhwala.Kutentha ndi chinyezi zimatha kuyendetsedwa m'chipinda chopoperapo mankhwala cha penti yamoto m'nyengo yozizira, koma kutentha kapena chinyezi sikungathe kuwongolera m'chilimwe, chifukwa kuziziritsa kumakhala kwakukulu kwambiri m'chilimwe.
Kumalo otentha kwambiri ndi chinyezi chachikulu, muyenera kukhazikitsa choziziritsa chapakati mchipinda chopoperapo mankhwala musanagwiritse ntchito madzizokutira, ndi mpweya wozizira uyenera kuperekedwa m'chilimwe kuti zitsimikizike kuti utoto wopangidwa ndi madzi umapangidwira bwino.
3. Zida zina
(1) Mfuti yopopera utoto yokhala ndi madzi
Nthawi zambiri, mfuti zopaka utoto zokhala ndi madzi zokhala ndi voliyumu yayikulu komanso ukadaulo wocheperako (HVLP) zimagwiritsidwa ntchito.Chimodzi mwazinthu za HVLP ndi kuchuluka kwa mpweya, komwe nthawi zambiri kumakhala 430 L / min, kotero kuthamanga kwa kuyanika kwa utoto wopangidwa ndi madzi kumatha kuwonjezeka.
Mfuti za HVLP zokhala ndi mpweya wambiri koma ma atomization otsika (15μm), zikagwiritsidwa ntchito m'malo owuma, zimauma mwachangu ndikupangitsa utoto wamadzi kuti usayende bwino.Chifukwa chake, mfuti yapakatikati komanso yapakati-voliyumu yokhala ndi atomization yayikulu (1μpm) ipereka zotsatira zabwinoko.
Ndipotu, kuthamanga kowuma kwa utoto wopangidwa ndi madzi sikukutanthauza kanthu kwa eni galimoto, ndipo zomwe angathe kuziwona ndizofanana, gloss ndi mtundu wa utoto.Choncho, popopera utoto wopangidwa ndi madzi, musamangofufuza mofulumira, koma muyenera kumvetsera kwambiri ntchito yonse ya utoto wamadzi, kuti mukhutiritse mwini galimotoyo.
(2) Mfuti yowomba penti yotengera madzi
Opopera mankhwala ena amaona kuti utoto wamadzi umachedwa kuuma poyerekeza ndi utoto wa zosungunulira, makamaka m'chilimwe.Izi zili choncho chifukwa utoto wopangidwa ndi zosungunulira umasanduka nthunzi mwachangu komanso umauma mosavuta m'chilimwe, pomwe umakhala wamadzizokutirasizimva kutentha kwambiri.Nthawi yapakati yowumitsa utoto wa utoto wopangidwa ndi madzi (5-8 min) imakhala yocheperako poyerekeza ndi utoto wopangidwa ndi zosungunulira.
Mfuti ndiyofunikiradi, yomwe ndi chida chowumitsa utoto wamadzi pamanja pambuyo popopera.Mfuti zambiri zokhala ndi utoto wopangidwa ndi madzi pamsika masiku ano zimawonjezera kuchuluka kwa mpweya kudzera mumphamvu ya venturi.
(3) Zida zophatikizika zosefera mpweya
Mpweya wosasefera wosasefedwa uli ndi mafuta, madzi, fumbi ndi zonyansa zina, zomwe zimawononga kwambiri ntchito zopopera utoto zamadzimadzi ndipo zimatha kuyambitsa zolakwika zosiyanasiyana zamakanema a utoto, komanso kusinthasintha kwapang'onopang'ono kwa mpweya ndi voliyumu.Kukonzanso chifukwa cha zovuta zamtundu wa mpweya sikungowonjezera ndalama zogwirira ntchito komanso zakuthupi, komanso kumalepheretsa ntchito zina.
Njira zodzitetezera pomanga utoto wamadzi
1. Zosungunulira zazing'ono za organic zimalola utoto wopangidwa ndi madzi kuti usagwirizane ndi gawo lapansi, ndipo madzi ake osungunulira amawonjezera nthawi yowuma.Kupopera mbewu mankhwalawa madzi kumapangitsa kuti madzi azitsika mosavuta pamizere yokhuthala kwambiri, kotero simuyenera kupopera mbewu mankhwalawa kwa nthawi yoyamba!
2. Chiŵerengero cha utoto wopangidwa ndi madzi ndi 10: 1, ndipo 10g yokha ya madzi osungunuka madzi amawonjezeredwa ku 100g ya utoto wamadzi amatha kutsimikizira kuphimba kwa utoto kolimba kwa madzi!
3. Mafuta ayenera kuchotsedwa ndi degreaser yochokera ku mafuta musanawapentire, ndipo mafuta opangira madzi ayenera kugwiritsidwa ntchito kupukuta ndi kupopera, zomwe ndizofunikira kwambiri, chifukwa zimatha kuchepetsa kwambiri mwayi wamavuto!
4. Funnel yapadera ndi nsalu yapadera ya fumbi iyenera kugwiritsidwa ntchito posefa madzizokutira.
