Abstract
A kneader includes a kneader main body including a casing including a kneading chamber and a kneading portion that is disposed in the casing and kneads a material in the kneading chamber. The material supplied to the kneading chamber includes a resin material, an inorganic additive added to the resin material, and a coupling agent for enhancing affinity of the inorganic additive for the resin material. The kneader further includes a kneading monitoring portion that monitors a kneading state of the material by detecting a reaction product that is generated by a reaction between the coupling agent and the inorganic additive.
Claims5
A kneader, comprising:
- a kneader main body that has:
- a casing defining a hermetically sealed internal space having a kneading chamber in which a material is kneaded, the material generating a gaseous reaction product while being kneaded;
- a kneading portion for kneading the material in the kneading chamber;
- and
- a kneading monitoring portion that monitors a kneading state of the material in the kneading chamber by detecting the gaseous reaction product generated in the kneading chamber, and including:
- a detector which is provided in the hermetically sealed internal space of the kneader, and detects an amount of the gaseous reaction product generated in the kneading chamber,
- a calculator which is provided outside of the casing and calculates a reaction rate of the material based on the amount of the gaseous reaction product, and
- an estimation portion which is provided outside of the casing, and estimates a kneading state of the material by using the calculated reaction rate, and
- a controller adapted to control the operation of the kneading portion based on the kneading state of the material estimated by the estimation portion.
A kneading method for kneading a material including a resin material, an inorganic additive added to the resin material, and a coupling agent for enhancing affinity of the inorganic additive for the resin material by using a kneader that includes a casing defining a hermetically sealed internal space having a kneading chamber in which the material is kneaded, and a kneading portion for performing an operation of kneading the material in the kneading chamber, the kneading method including:
- kneading the material in the kneading chamber while monitoring a kneading state of the material by:
- detecting an amount of a gaseous reaction product generated by a reaction between the coupling agent and the inorganic additive in the kneading chamber by a detector provided in the hermetically sealed internal space;
- calculating a reaction rate of the material based on the amount of the gaseous reaction product by a calculator provided outside of the casing;
- estimating a kneading state of the material by using the calculated reaction rate by an estimation portion provided outside of the casing, and
- controlling the operation of the kneading portion based on the kneading state of the material estimated by the estimation portion.
A kneading method for kneading a material including a resin material, an inorganic additive added to the resin material, and a coupling agent for enhancing affinity of the inorganic additive for the resin material by using a kneader that includes a casing defining a hermetically sealed internal space having a kneading chamber in which the material is kneaded, and a kneading portion for performing an operation of kneading the material in the kneading chamber, the kneading method including:
- kneading the material in the kneading chamber;
- and monitoring a kneading state of the material being kneaded by:
- detecting an amount of a gaseous reaction product generated in the kneading chamber by a reaction between the coupling agent and the inorganic additive, at a location in the hermetically sealed internal space of the casing above the kneading chamber.
