Abstract: A low-carbon emission casting and a mold thereof, and equipment comprising the low-carbon emission casting are provided. The low-carbon emission casting includes a casting main body, a plurality of embedded parts, and a connecting portion. The casting main body is formed by casting and solidification at room temperature. The plurality of embedded parts are embedded in the casting main body. The connecting portion is disposed on at least one surface of the casting main body. The mold of the low-carbon emission casting includes a mold bottom portion, a plurality of mold side portions, and at least one supporting member. The equipment comprising the low-carbon emission casting includes the low-carbon emission casting and a machining device. The machining device is connected to the low-carbon emission casting.

Abstract: A low-carbon emission mineral casting material and a manufacturing method thereof, and an equipment including a low-carbon emission mineral casting are provided. The low-carbon emission mineral casting material includes a bonding agent, a first aggregate, and an additive agent. The bonding agent includes one or more of silicate, aluminate, or iron-aluminate. A first particle diameter of the first aggregate is less than or equal to 15 mm. The low-carbon emission mineral casting material provided by the present application has better heat resistance, lower thermal conductivity, lower expansion coefficient, and better shock-absorbing performance than traditional casting material.

Abstract: An oligomer (2,6-dimethylphenylene ether) is provided. Its structure is shown as follows: which comprises separately independent hydrogen; alkyl or phenyl; separately independent —NR—, —CO—, —SO—, —CS—, —SO2—, —CH2—, —O—, null, —C(CH3)2—, or and a hydrogen, The features of the cured products include a high glass-transition temperature, a low dielectric feature, preferred thermal stability, and good flame retardancy. The present invention effectively controls the number-average molecular weight of the product to obtain excellent organic solubility.
