Mkulu aluminiyamu gulu njerwa

Ubwino wazogulitsa: kutsika kwakukulu, kukana kwamphamvu kwa asidi ndi slag yamchere, kutentha kwamphamvu kwamakina, kulimba kwamphamvu kwamphamvu, kusungunuka, kukana kutentha.

Mafotokozedwe Akatundu

Njerwa yamitengo yayitali kwambiri ya aluminiyumu Njerwa yama sintered ya aluminiyamu yodziwika bwino imakhala yokhazikika, yopangidwa ndi gawo logwira ntchito komanso chosanjikiza kutentha. Njerwa yonyamulirayo ndi yopangidwa ndi magawo osanjikiza komanso osanjikiza kutentha, ndipo imakhala ndi zotentha zosagwira moto komanso zotchingira kutentha. Wosanjikiza wogwira ntchito ndi wosanjikiza wa kutentha amapatukana mosiyana ndikusakanikirana pokonzekera, kenako ndikupangidwa ndikuwombera limodzi. Gulu logwiritsa ntchito njerwa limakhala lolimba kwambiri ndikulumikiza kutentha. Wosanjikiza wogwira ntchito ali ndi kutentha kwambiri kukana, asidi ndi kukana kwa alkali, kukana kumva kuwawa, mphamvu yayikulu, kukhazikika kwamphamvu kwamatenthedwe, magwiridwe antchito abwino otchingira kutentha ndi mphamvu yazitsulo zotchingira kutentha. mkulu. Njerwa yomweyi imatha kukwaniritsa zofunikira pazogwiritsa ntchito uvuni, imatha kuzindikira kupulumutsa mphamvu ndikuchepetsa, ndikuchulukitsa moyo wautumiki woyatsira. Njira yokonzekera ndi yasayansi komanso yololera, yosavuta kugwiritsa ntchito, ndipo ndi yoyenera lamba wowombera ndi lamba wa fyuluta yayikulu yoyenda. Kuphatikiza apo, zopangidwa ndi njerwa zopangidwa ndi alumina ambiri zimagwiritsidwa ntchito m’mafakitale osiyanasiyana monga magetsi, zitsulo, zitsulo zopanda feri, petrochemicals, galasi, simenti ndi zomangira.

Kufotokozera kwa njerwa zopangidwa ndi aluminiyamu yayikulu:

1. Makhalidwe ndi kagwiritsidwe:

Ili ndi kukonzanso kwakukulu, kutentha kwamphamvu kwa asidi ndi slagine slag, ndi mphamvu yayikulu yamakina kutentha kwambiri, kotero imagwiritsidwa ntchito kwambiri pamakampani azitsulo ndi ziwaya zina. Amagwiritsidwa ntchito makamaka popangira matenthedwe osiyanasiyana monga nsonga zamagetsi, ng’anjo zowotchera moto, masitovu otentha, makwerero, ng’oma zachitsulo, ngolo zachitsulo, ma simenti, ma galasi, ndi zina zambiri. , simenti ndi mafakitale ena.

2. Zogulitsa pazinthu: njerwa zokhazikika, zapadera komanso zapadera, njerwa zapadera komanso zopangidwa mwapadera.

3. Njerwa zosanja ndi zinthu zopangira mawonekedwe ena ndi kukula kwake. Njerwa zaumboni zimakhala ndi matenthedwe abwino ndipo ndizoyenera kutenthetsera moto, zotchingira zosiyanasiyana, chimfine, zipinda za utsi, ndi zina zambiri. Pali mitundu yambiri yazida zopangira njerwa, ndipo zigawo zake zazikulu ndi dothi, miyala, mchenga, miyala, ufa ndi zina zotero. Njerwa zosakhazikika nthawi zambiri zimagawika m’magulu awiri, osakhazikika osanjikiza ndi owumbidwa. Zosasunthika zakapangidwe kotsalira: komwe kumatchedwanso kuti kotheka, ndi ufa wosakanizika wa powdery wopangidwa ndi mitundu ingapo yamagulu kapena akaphatikizidwe ndi kumangiriza kumodzi kapena angapo. Pogwiritsidwa ntchito, imasakanizidwa ndi chimodzi kapena zingapo zamadzimadzi ndikusakanikirana chimodzimodzi. Phunzitsani kuyenda mwamphamvu. Zida zopangira zokongoletsa: njerwa zambiri zopangidwira, mawonekedwe ake amakhala ndi malamulo oyenera, ndipo amathanso kukonzedwa kwakanthawi molingana ndi zosowa pomanga ndi kudula.

Zizindikiro zakuthupi ndi zamankhwala

Mapulogalamu

Yoyenera kuwombera lamba ndi lamba wa fyuluta wa uvuni waukulu. Kuphatikiza apo, zopangidwa ndi njerwa zopangidwa ndi alumina ambiri zimagwiritsidwa ntchito m’mafakitale osiyanasiyana monga magetsi, zitsulo, zitsulo zopanda feri, petrochemicals, galasi, simenti ndi zomangira.
