Casting coating chinhu chekubatsira chakaputirwa pamusoro pe mold kana core, iyo inobata basa rakakosha mukuvandudza pamusoro pemhando yekukanda. MaChina ekutanga kukanda mhizha, anopfuura makore 3000 apfuura, vakagadzirira uye vakabudirira kushandisa coating coating, zvichiita mupiro wakakura mukuvandudza tekinoroji yekukanda.
Nekuvandudzwa kwekugadzirwa uye tekinoroji, izvo zvinodikanwa zvemhando yekukanda zviri kuwedzera zuva nezuva. Kuti vawedzere kukwikwidzana kwezvigadzirwa zvavo, mafekitari mazhinji anozvipira kutsvagurudzo yejasi nekuda kwezvinetso mukugadzira.
Izvi zvinotevera, muchidimbu nezvekukandira kwekukanda kwematambudziko akati wandei.
Kutanga, zvinyorwa zvakasimba uye simba rekuvhara
Ikozvino, iyo yekupfeka inoshandiswa kune resin yakasungirirwa jecha inoda iyo yakasimba yakasimba yemukati uye yakakwira simba, izvo zvinonyanya kukonzerwa nekufunga kuviri.
1. Chinja kune maitiro ejecha mold
Kare, ivhu jecha nyoro jecha mhando kwete pendi, pendi chete kushandiswa ivhu jecha yakaoma mhando. Nekuda kwesimba revhu revhu jecha rakaoma mhando yakaderera kwazvo, uye kuita kukanda castings kwakakosha kana hombe castings, chinodiwa chekuputira kwete chete kuumba yekuzviparadzanisa layer, uye zvinoda infiltration casting coating pamusoro pezvinotevera, zvakanakisa. zvinosanganisira 3 ~ 4 jecha, ita kuti mold iwedzere, saka, viscosity yepende haigone yakakwira zvakanyanya, iyo yakasimba yemukati haina kunyanya kukwirira.
2. Funga nezvekuchengetedza simba, kuchengetedza kwezvakatipoteredza uye kuderedza mari yekugadzira
Zvitakuri zvemvura zvinoshandiswa mumajasi, kunyanya mvura uye madoro. 20 mazana emakore 70 ~ 80 nguva, yakanga yashandiswa haidi kuomeswa kana kupisa, inogona kushandura chlorine chizvarwa hydrocarbons, senge dichloromethane, semutakuri wependi. Nekuda kwehuchetura hwayo, kukanganisa kwayo kune zvakatipoteredza sezvainoputika mumhepo, uye kudhura kwayo kukuru, iko zvino haichashandiswa.
Chechipiri, iyo mbishi zvinhu zvinoshandiswa pakupfekedza
Kune akawanda marudzi ezvakagadzirwa zvinhu zvinoshandiswa mukukandira coating, uye ivo vanozowedzerwa nguva dzose pahwaro hwekuvandudzwa kweindasitiri yezvinhu.
1. refractory aggregate
Refractory aggregate ndiyo chikamu chikuru mukuputira, uye kunaka kwayo uye kusarudzwa kune simba guru pakushandiswa kwekushandisa kwejasi. Panguva imwecheteyo, pakusarudza kuunganidzwa, isu tinofanirawo kuita ongororo yakazara muhutsanana hweindasitiri uye hupfumi.
2. mutakuri,
Iwo makuru anotakura anoshandiswa mukukanda machira imvura, madoro uye chlorinated hydrocarbons. Parizvino, nekuda kwekutariswa kwemutengo uye mamiriro ezvakatipoteredza, anoshandiswa zvakanyanya ku chlorine hydrocarbon semutakuri wejasi, iyo yakawanda ndeyemvura yakavakirwa coating uye doro-based coating.
