摘要:
A metering component for a two-component dispensing gun includes a first metering rod and a second metering rod. The first metering rod includes a first tip section at one end that terminates into a first intermediate sealing section. The first intermediate sealing section terminates at a first base section at an opposite end of the first tip section. The second metering rod includes a second tip section at one end terminating in a second intermediate sealing section, wherein the second intermediate sealing section terminates at a second base section at an opposite end of the second tip section. The first metering rod is interconnected to the second metering rod at the first base section and the second base section.
摘要:
The invention described herein generally pertains to the use of low boiling point, low vapor pressure blowing agents with froth polyurethane or polyisocyanurate foams to achieve superior cavity filling than when using conventional higher vapor pressure or more ozone-depleting blowing agents.

The invention described herein generally pertains to the use of low boiling point, low vapor pressure blowing agents with froth polyurethane or polyisocyanurate foams to fill hollow cavities (particularly window lineals) and which have lowered exotherms, which prevent deformation of the hollow cavity (e.g., window lineal) and additional achieve filling of longer lengths of window lineals by increasing the foaming and gel times of the reaction.
摘要:
A carton for a portable two-component polyurethane foam spray kit has front and rear panels interconnected at their vertically extending ends with carton sides to form a rectangular opening closed at its bottom by bottom flaps. A top cover flap has valve openings allowing the kit user to open and close pressurized nullAnull and nullBnull polyurethane cylinders carried in the carton without opening the carton. The carton is carried by a strap secured to the cylinders extending through the top of the carton. A closeable, punch-out front flap formed as part of the front panel allows the kit hoses to be attached to the cylinders and the dispensing gun and stored for shipment and use within the carton between the cylinders and the front panel.
摘要:
An improved multi-component mixing and dispensing apparatus having a replaceable nozzle associated therewith in which plural components are mixed before dispensing thereof. The apparatus includes improved component feed systems to maintain each component to be mixed and dispensed in a segregated condition until mixing is desired, such that the apparatus is especially suitable for the mixing and dispensing of chemically reactive components. The component feed systems include internal passages within the apparatus and is selectively actuated valve which is operable to allow flow of a component to an outlet port formed in the apparatus. A mixing and dispensing nozzle may be coupled into the apparatus so as to communicate with the outlet ports of the component feed systems, wherein improved mixing of the plural components is achieved within the nozzle assembly. The component feed systems include self-cleaning structures to ensure that the internal passages remain unblocked, and the apparatus further includes structure to selectively render the apparatus nonoperational when desired. A replaceable mixing and dispensing assembly which may be used with the dispensing apparatus is disclosed, which allows more thorough metering and mixing of plural components within a kinetic mixing chamber, and may include a second stage of mixing if desired. The nozzle assembly may also be configured to have a plurality of nozzle tip configurations integrally formed therein wherein each of the nozzle tips may be selectively exposed for use.
