Pezani Ubwino Wapamwamba ndi Drum Pre-treatment & Heating
Mafotokozedwe Akatundu
- Tikubweretsa kusintha kwa ng'oma ndi makina otenthetsera asanayambe mankhwala. Monga otsogola pamakampani opangira malata, timamvetsetsa mbali yofunika kwambiri yomwe chithandizo chamankhwala chisanakhalepo pakuwonetsetsa kuti mankhwala opangira malata ndi apamwamba kwambiri. Ndi ukadaulo wapamwamba komanso kapangidwe katsopano, tikufuna kusintha momwe chisamaliro chimachitikira.
Mwachizoloŵezi, makampani opangira malasha otentha a m'nyumba amadalira akasinja a konkire ndi granite kuti atenthetsedwe kale. Komabe, pakukhazikitsidwa kwaukadaulo wopangira malata otentha ku Europe ndi United States, kufunikira kwa njira zina zogwirira ntchito komanso zodalirika kukukulirakulira. Apa ndipamene matanki athu otolera a PP (polypropylene)/PE (polyethylene) amayamba.
Ma ng'oma athu okonzeratu ndi makina otenthetsera amaphatikiza njira zoyambira zochotsera dzimbiri, kuchotsa dzimbiri, kutsuka madzi, kuyika zowonjezera ndikuumitsa kukhala ntchito imodzi yopanda msoko. Ndi yankho la zonse-mu-limodzi timachotsa kufunikira kwa matanki angapo osungira ndikufewetsa njira yonse yokonzekera. Izi sizimangowonjezera luso komanso zimachepetsa ndalama zogwirira ntchito.
Ubwino waukulu wa ng'oma zathu zowonongeka ndi machitidwe otenthetsera ndi kugwiritsa ntchito zipangizo za PP / PE. Zidazi zimadziwika chifukwa cha kukana kwambiri kwa dzimbiri komanso kuwonongeka kwa mankhwala. Zotsatira zake, akasinja athu otsogola amapereka magwiridwe antchito apamwamba komanso olimba poyerekeza ndi akasinja achikhalidwe a konkriti. Kugwiritsiridwa ntchito kwa zinthuzi kumatsimikiziranso kuti machitidwe athu ndi ogwirizana ndi chilengedwe komanso akutsatira miyezo yapadziko lonse ya chilengedwe.
Kuwonjezera pa kugwiritsa ntchito zipangizo zapamwamba kwambiri, ng'oma zathu zokonzekera ndi zotenthetsera zimakhala ndi zipangizo zamakono zopangira kutentha. Izi zimatsimikizira kuwongolera kolondola komanso kosasinthika kwa kutentha panthawi yonse yochizira, kupititsa patsogolo kukonzanso kwamankhwala opangira malata. Dongosololi limakhalanso ndi mawonekedwe osavuta kugwiritsa ntchito komanso osavuta kugwiritsa ntchito ndikuwongolera.
Kaya muli ndi nyumba yaying'ono yopangira malata kapena nyumba yayikulu yamafakitale, ng'oma zathu zokonzeratu ndi zida zotenthetsera zimapangidwira kuti zikwaniritse zomwe mukufuna. Timapereka zosankha zomwe mungasinthire kuti mukhale ndi mitundu yosiyanasiyana yopanga ndi kukula kwake. Ndi mankhwala athu, mukhoza kutenga galvanizing ntchito zanu kukwera kwatsopano kwa dzuwa, zokolola ndi khalidwe.
Lowani nawo kusintha kwa kutentha kwa dip galvanizing pre-treatment. Ikani ndalama mu ng'oma zathu zokonzedweratu ndi makina otenthetsera ndikupeza mphamvu yosintha yaukadaulo wapamwamba. Khulupirirani ukatswiri wathu ndipo tiyeni tikuthandizeni kukwaniritsa miyezo yapamwamba kwambiri yazinthu zanu zamagalasi. Lumikizanani nafe lero kuti mudziwe zambiri zamayankho athu atsopano.
Kutentha koyambirira
Gwiritsani ntchito kutentha kwa zinyalala za gasi kuti mutenthetse akasinja onse osayankhidwa, kuphatikiza kuchotsa mafuta, pickling ndi plating yothandizira. Dongosolo la kutentha kwa zinyalala limaphatikizapo:
1) Kuyika kwa ophatikiza kutentha exchanger mu chitoliro;
2) Seti imodzi ya PFA yosinthira kutentha imayikidwa kumapeto kwa dziwe lililonse;
3) Njira yamadzi yofewa;
4) Kuwongolera dongosolo.
Kutentha koyambirira kumakhala ndi magawo atatu:
① Chosinthira kutentha kwa gasi
Malingana ndi kuchuluka kwa kutentha komwe kumayenera kutenthedwa, chophatikizira chophatikizira kutentha kwa flue chimapangidwa ndi kupangidwa, kotero kuti kutentha kukhoza kukwaniritsa zofunikira zotentha. Ngati kokha kutentha zinyalala za chitoliro sangathe kukumana Kutentha kutentha kufunika kwa chisanadze mankhwala, ya ng'anjo otentha mpweya akhoza kuwonjezeredwa kuonetsetsa chitoliro mpweya voliyumu.
Chojambulira kutentha chimapangidwa ndi chitsulo chosapanga dzimbiri chosagwira kutentha kapena chitoliro chachitsulo chosasunthika 20 # chokhala ndi zokutira zatsopano za infrared nano kutentha kwambiri zopulumutsa mphamvu zolimbana ndi dzimbiri. Mphamvu yoyamwitsa kutentha ndi 140% ya kutentha komwe kumatengedwa ndi zida wamba zotenthetsera kutentha.
② PFA chosinthira kutentha
③ Kuyanika uvuni
Zinthu zonyowa zikalowa mubafa la zinki, zimachititsa kuti madzi a zinki aphulike ndikuphulika. Choncho, pambuyo plating thandizo, kuyanika ndondomeko ayeneranso anatengera kwa mbali.
Nthawi zambiri, kutentha kwa kuyanika sikuyenera kupitirira 100 ° C ndipo sikuyenera kukhala kotsika kuposa 80 ° C. Apo ayi, zigawozo zikhoza kuikidwa mu dzenje loyanika kwa nthawi yaitali, zomwe zingayambitse kuyamwa kwa zinc chloride mu mchere mosavuta. filimu yothandizira plating pamwamba pa zigawozo.
