Composition and method for cleaning aluminum at low temperatures

Composition and method for cleaning aluminum at low temperatures. Binns, Robert Eric (Amchem Products, Inc., USA). U.S. US 4009115 22 Feb 1977, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C11D007-08. NCL: 252142000. APPLICATION: US 74-442726 14 Feb 1974. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) The aq. acid cleaning soln. contains HF, H2SO4, and surfactant and is used for Al containers at 120-125.degree.F and pH 1. 58229-81-5 and 7664-39-3 are cas registry numbers of chemicals which are used as reagents here.0-1.8. Thus, a drawn 3004 [37321-73-6] Al alloy container covered with Al fines was sprayed 60 s with a soln. contg. HF 0.02, H2SO4 4.0 and Tergitol 08 [126-92-1] anionic surfactant 1.0 g/L. After rinsing, the container was water-break-free and bright on the interior and exterior. .

Thermally insulating coating applied on the walls of buildings and its use

Thermally insulating coating applied on the walls of buildings and its use. Gachot, Jean (Fr. ). Fr. Demande FR 2520406 A1 29 Jul 1983,12 pp. (French). (France). CODEN: FRXXBL. CLASS: IC: E04B001-76; C09J001-00; E04F013-18. APPLICATION: FR 82-957 22 Jan 1982. DOCUMENT TYPE: Patent CA Section: 58 (Cement, Concrete, and Related Building Materials) Section cross-reference(s): 38, 42 Thermally insulating sheathing applied to the outer or inner walls of buildings consists of plates of an expanded material (e.g., polystyrene [9003-53-6] or glass) attached to the walls by a layer of adhesive material contg. a synthetic resin and 31 hydraulic binder, and covered on the outside by another layer of this material, which confers enough elasticity and mech. resistance to envelop the dimensional variations of the plates and which evenly fills the spaces between adjacent plates to surround the plates and connect the wall directly to the outside layer. The coating materials may consist of compds. (e.g., an anionic agent and an alkyl sulfate), which are mixed just prior to application to react and form gas bubbles inside the material. Thus, a liq. 1318-00-9 and 26499-65-0 are also in the experiment. component of synthetic resin 2-20, Na lauryl ether sulfate (I) [9004-82-4] 2-10, mineral fibers 10-30, polyoxyethylated nonylphenol [9016-45-9] grinding aid 1-5, stabilizing rust-proofing agent 1-5, and water 40-60 wt.% was combined with approx. equal amts. of a solid component contg. plaster 40-60, Na ethylhexyl sulfate II [126-92-1] 2-10, Al2(SO4)3 or AlPO4 5-10, modified Me cellulose [9004-67-5] 1-5, and vermiculite 20-40 wt.% and the compn. was immediately applied as a 1-5 mm layer to a wall, expanded polystyrene plates were applied before the coating set, leaving 1-2 cm long spaces, and addnl. coating was applied to completely fill the spaces and cover the outside of the plates. Upon setting, the anionic I reacts with II to form gaseous bubbles, which are trapped in the material, expand it, and impart a structure with enclosed pores, which has remarkable heat insulating properties, elasticity, and mech. resistance. .
