Filed:

Jun 20, 2000

Appl. No.:

09/597509

Inventors:

Hong-Son Ryang - Camarillo CA
Scott A. Schroeder - Newbury Park CA

Assignee:

Rockwell Technologies, LLC - Thousand Oaks CA

International Classification:

B22F 312

US Classification:

419 36, 419 38

Abstract:

A method of strengthening green form parts made from metal powder requires the use of a cross-linkable polymer which, when cross-linking has been induced, retains its mechanical properties to a degree sufficient to prevent fracture or significant deformation of the green form part when subjected to heat sufficient to induce phase transformation and carbonization. The polymer is incorporated into a green form part and cross-linking induced, giving the green part additional strength which enables it to endure the consolidation process without failing. The required polymer can be part of the powder blend used to form the green form part, and induced to cross-link with heat or radiation. Alternatively, the green form part can be dipped in a thermoset resin that cross-links when cured.

International Classification:

B41J 201

US Classification:

347106, 347102

Abstract:

An apparatus and method for ink jet printing on textiles is disclosed, wherein the steps of pre-treating, ink jet printing, and post-treating the textile takes place at the ink jet printer. A preferred method includes the steps of applying a pre-treat to the textile, evaporating excess water from the pre-treat, ink jet printing a pattern on the pre-treated textile, evaporating water from the ink in the pattern, applying a binder/post-treat to the pattern and curing the binder. The textile printing apparatus prints on an untreated textile by having a first application device to apply a pre-treat aqueous solution to the textile. A first heating element is arranged to evaporate most or all of the water from the pre-treated textile as it passes. An ink jet printer then accepts the pre-treated textile and prints the desired pattern on it. A second heating element at the output of the printer evaporates water from the ink in the pattern as the printed textile passes.

Abstract:

A fire retardant polymer composition is provided. The fire retardant polymer composition is formed of a polymer material, a plurality of monomers of a polycondensed partially hydrolyzed chelated metal oxide precursor, and at least one flame retardant constituent. A process for making a flame retardant polymer composition is also presented. The process includes contacting a polymer material with a metal oxide sol comprising a liquid and a condensation product of a partially hydrolyzed chelated metal oxide precursor to form a mixture. The polymer material also is contacted with at least one flame retardant constituent. The polymer material is then polymerized or solidified.
