Mchanga wa dhahabu kwa kutupwa kwa ukingo wa mchanga

Maelezo Fupi:

Mchanga wa kauri wa Foundry, unaoitwa kitaalamu kama "Mchanga wa kauri wa Sintered kwa Foundry", pia jina lake kama ceramsite, ceramcast, sawa na cerabeads, baadhi ya nchi pia huitwa Mchanga wa Dhahabu, ni umbo zuri wa nafaka ya duara ambayo imetengenezwa kutoka kwa bauxite iliyokaushwa. Maudhui yake kuu ni oksidi ya alumini na oksidi ya Silicon. Mchanga wa kauri, una mali bora zaidi kuliko ile ya mchanga wa silika ili kupata utendaji bora katika uanzilishi. Ina kinzani ya juu, upanuzi mdogo wa mafuta, mgawo mzuri wa angular, mtiririko bora, upinzani wa juu wa kuvaa, kuponda na mshtuko wa joto, kiwango cha juu cha kurejesha.

Maelezo ya Bidhaa

Lebo za Bidhaa

Foundry Ceramic Sand, technically named as “Sintered Ceramic Sand for Foundry”, also named as ceramsite, cerabeads, ceramcast, some countries is also named Golden Sand, is good artificial spherical grain shape which is made from calcined bauxite . Its main content is aluminum oxide and Silicon oxide. Ceramic sand, has much better properties than that of silica sand to gain a better performance in foundry. It has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, High resistance to wear, crush and thermal shock, high reclamation rate.

Faida

Kaist ceramic foundry sand is about half as light as zircon and chromite, is about third as light as fused ceramic sand. Compared to these natural sand and other foundry media (the material is able to turn out about twice the number of molds per unit weight). Kaist ceramic foundry sand can deliver mold and core packages with a range of benefits that include higher-strength sand casting packages, with high heat resistance, low thermal expansion, improved final part resolution and a smoother surface finish. It can also be handled very easily, saving labor and transfer power costs. However, the manufacturer recommends paying attention to the amount of binder addition.

Maombi

Kama nyenzo ya upande wowote, mchanga wa kauri wa KAIST unatumika kwa asidi na resini za alkali.

Inaweza kutumika sana kwa chuma cha kutupwa, chuma cha kutupwa na utupaji wa metali zisizo na feri, kama vile utupaji wa povu uliopotea, mchanga uliofunikwa, mchanga wa resin, sanduku la msingi baridi, utupaji wa usahihi, na uchapishaji wa 3D.
