摘要:
The present invention relates to a method for manufacturing an automobile weather strip having a seal part having a sectional shape of U and a sealing function, a coupling member formed unitarily with the seal part in such a manner as to be coupled to a flange portion of an automobile, and a seam material insertedly disposed inside the coupling member, the method including: (a) weather strip manufacturing step wherein the seam material and a thermoplastic elastomer are extruded and molded; (b) pretreatment step wherein the surface of the weather strip manufactured is pretreated; (c) slip agent applying step wherein a slip agent made by mixing silicone and polyurethane is applied to the surface of the weather strip pretreated through the pretreatment step; and (d) curing step wherein the slip agent coating layer formed through the slip agent applying step is cured. According to the present invention, the automobile weather strip and the method for manufacturing the same can improve emotional quality, compression set performance, reinforcement, and durability thereof.
摘要:
A process of making a thermoplastic polyurethane by the reaction of (1) a hydroxyl terminated polyester intermediate, wherein the hydroxyl terminated polyester intermediate is comprised of repeat units that are derived from adipic acid and a glycol component comprising 1,3-propylene glycol, and said hydroxyl terminated intermediate has a number average molecular weight which is within the range of 500 to 10,000 Daltons, (2) a diisocyanate; and (3) a glycol chain extender. This thermoplastic polyurethane by this process is unique in that it has a greatly reduced tendency to bloom. This is highly desirable in applications where high clarity is desired because blooming causes articles containing the thermoplastic polyurethane to be hazy or foggy in appearance. Blooming can also reduce the ability of an article made with the thermoplastic polyurethane to be securely bound to another article with an adhesive.

The present disclosure relates to a method and an extrusion apparatus (100, 200) to manufacture a soot preform (130). The extrusion apparatus (100 and 200) includes a feed-hopper (104) to feed silica slurry (102) which is pushed within the barrel (106), an iris frame (116) exhibiting a variable diameter to control a diameter of the soot preform (130), drying furnace (118), debinding furnace (122) eliminates moisture and one or more stabilized binders in the soot preform (130) to obtain a glass preform (138) from which an optical fiber (142) is drawn.
摘要:
A continuous process for making a flexible porous dissolvable solid structure with open celled foam. The continuous process has the steps of preparing a pre-mixture comprising surfactant, polymer, water, and optionally plasticizer; aerating the pre-mixture to form a wet aerated pre-mixture; extruding the wet aerated pre-mixture to form one or more sheets on a belt; and drying the sheets to form an Article having an open celled foam.
摘要:
An induction heating roll device includes first and second resin processing bodies which roll or knead the resin material by interposing the resin material between the first and the second resin processing bodies. At least one of the first and the second resin processing bodies is a roll 5a. An induction heating coil 25 which is provided inside of the roll 5a and a cooling medium supply device 27 which supplies a cooling medium to a cooling medium flow channel 37 which is formed inside of the roll 5a are further provided. The induction heating coil 25 performs induction heating of the roll 5a, and the cooling medium supply device 27 cools the heated roll 5a by supplying a cooling medium to the cooling medium flow channel 37.
