Systems and methods include a computer-implemented method for manufacturing a binder for spraying onto tools. A binder is manufactured for binding compacts onto a tool substrate. The binder is designed to provide a coating strength on the tool substrate. The binder includes: a metal selected from iron (Fe), cobalt (Co), and nickel (Ni); an alloy including the metal selected from Fe, Co, and Ni; or a refractory alloy selected from tungsten, tantalum (Ta), molybdenum (Mo), and niobium (Nb). An ultra-high-pressure, high-temperature operation is performed on pure wurtzite boron nitride (w-BN) powder to synthesize w-BN and cubic boron nitride (c-BN) compact. A binder-compact mixture is produced by turbulently mixing the binder with the compact in a mixer within a vacuum. The binder-compact mixture is thermally sprayed onto a tool substrate to coat the tool.

Equipment and processes for curing and decarboxylating botanical oils, and in particular oils such as cannabidiol (CBD) and tetrahydrocannabinol (THC) from plants of the genus Cannabis (including both THC-lacking industrial hemp and THC-bearing varieties) are described. Lower temperatures, extended cure cycles and inert-gas processing improve product quality and reduce undesired oxidation, resulting in clear, homogenous oils with less tendency to crystallize.

Disclosed are a graphene material production device and a system including the device. The device includes: a first reaction component, a second reaction component and a negative pressure generating component. The first reaction component includes a first reaction chamber and a first material outlet arranged at a bottom of the first reaction chamber.

A suction hole of the negative pressure generating component is provided inside the second reaction chamber. The use of the device in the process of producing a graphene material by a redox method can overcome the problem that the viscous material is difficult to transfer, thereby reducing the production difficulty and effectively improving the production efficiency of graphene materials.

A manhole for a polymerization unit having a through-hole formed with a shoulder matching a corresponding shoulder of a plug of a closure member operatively inserted in the through-hole. The through-hole can be closed with a minimum clearance, such that polymer particles do not deposit in the gap between the wall of the unit and the plug of the closure member.
