摘要:
A cutting drill includes a shank having a hole and formed to be gripped in a tool holder, and a drill body having a rod shape and locked into the hole of the shank. The shank has an axis around which the drill body rotates. The drill body has a cutting-edge portion forming a tip portion of the drill body and a neck portion having a diameter smaller than a diameter of the cutting-edge portion. The cutting-edge portion has a first cutting-edge portion and a second cutting-edge portion formed between the first cutting-edge portion and the neck portion. The first cutting-edge portion is contiguous to the second cutting-edge portion by a step portion such that the second cutting-edge portion has a diameter which is smaller than a diameter of the first cutting-edge portion.
摘要:
There is provided a coating composition which comprises (A) a synthetic resin having functional group, (B) a stain-proofing component which is a liquid polydialkylsiloxane having functional group or a liquid fluoropolyether having functional group and (C) a curing agent, and the composition is excellent in a stain-proofing property, particularly removability of oily stain, thereby enabling scribbling to be easily wiped off, and is suitable for outdoor coating being excellent in weather resistance and adhesion.
摘要:
A durable water repellent agent comprising a repellent and a fluorine-containing resin, wherein the repellent comprises at least one member selected from the group consisting of a perfluoroalkyl group-containing substance (I), a fluorine-containing surfactant (II), a fluorine-containing oil (III), a fluorosilicone oil (IV) and a silicone oil (V), the solid content weight ratio between said repellent and said fluorine-containing resin being (repellent):(fluorine-containing resin)=50:50 to 99:1.
摘要:
A lance in a converter is supported at a first part thereof on a gimbal mechanism supported on a bridge supported on rotation devices supported on a lance carriage above the converter and operating to drive the bridge and the first part of the lance to undergo a revolutionary motion, and is held at a second part thereof below the first part against horizontal movement by another bearing device, whereby the lance is driven in gyratory motion about the center of the second part as a central node, the radius and speed of gyration of the working end of the lance being adjustable. Pertinent parts of the lance carriage, which can be raised and lowered in guided vertical movement by a hoisting device, are provided with cutout recesses into which the lance in vertical state at the time of installation can be placed by being moved sidewise in horizontal movement, whereby the installation and removal of the lance is greatly facilitated.
摘要:
It is an object of the present invention to provide an aqueous dispersion and a waterproofing agent, which are of the aqueous one-component type and easy and simple to apply and have both a decorative effect and enough waterproofing effect. The aqueous dispersion of the present invention comprises an organosilicon compound (1) represented by the general formula (I): and a fluorine-containing resin (2) comprising an aqueous fluororesin dispersion, and the weight ratio, on the solid basis, between said organosilicon compound (1) and said fluorine-containing resin (2) is (organosilicon compound (1)):(fluorine-containing resin (2))=60:40 to 97:3.
