A temperature sensor (10) for measuring a temperature of a mixture being mixed in an internal mixer includes a fixed part having a substantially cylindrical body (12) and a removable part (16) of domed shape arranged inside a conduit of the body. The temperature sensor also includes a blowing stem (14) in communication with a source of compressed air that extends along a conduit (12c) of the body and terminates at an outlet end (14a) disposed in the removable portion (16), whereby the compressed air exits the blowing stem (14) and passes uninterruptedly through a temperature measuring element or elements at a contact end (16b) of the removable portion. A combination of an internal mixer and a temperature sensor for measuring a temperature of a mixture being mixed in the internal mixer is also disclosed.

The present disclosure provides a rigid high-gloss wear-resistant and scratch-resistant flooring. The flooring includes a surface layer, an intermediate Spc layer, and a decorative layer that are laminated; where the surface layer is prepared by combining a melamine glue and a color film; the intermediate Spc layer is prepared by mixing polyvinyl chloride resin, calcium carbonate, a plasticizer, and a stabilizer; and the decorative layer is prepared by a high-temperature material. The rigid high-gloss wear-resistant and scratch-resistant flooring is prepared by the melamine glue and the special color film, has an intermediate Spc layer, and has the decorative layer on a back side. The flooring is prepared by three different layers through a high temperature and a high pressure. The flooring has a surface that is highly wear-resistant, extremely scratch-resistant, cigarette burning-resistant, and non-deformable, and is suitable for use in various public places, with various styles, diverse specifications, and stability.

A multi-component fluid delivery system includes a heater system. The heater system includes an improved fluid preheating system based on a high conductivity fluid heat exchange manifold that is coupled to external heater elements (e.g., powered via electricity). These techniques can provide more surface area for heating fluid and is external to the fluid passages, making service or replacement much easier. These techniques can utilize etched foil or wire wound heater elements that operate at a lower internal temperature than cartridge heaters, and thus can be inherently more reliable.

A method includes feeding a heated polymer additive at a first temperature into a continuous mixer at a first feed rate. The method includes feeding a heated abrasive solid material at a second temperature into the continuous mixer at a second feed rate. The heated abrasive solid material and the heated polymer additive are mixed in the continuous mixer to form a first mixture.
