    摘要： A polyurea resin molding composition for RIM use comprising (a) polyoxyalkylenpolyamine having an average molecular weight greater than about 400 and a plurality of terminal primary or secondary amino groups, (b) an aromatic polyamine and/or xylylenediamine and (c) a polyisocyanate. The component (a) contains dispersed therein a polymer prepared by the in situ polymerization of at least two different olefinically unsaturated monomers in the presence of a radical polymerization initiator, the ratio of the average amino equivalent of said polyamines (a) and (b) in combination to the average NCO equivalent of said polyisocyanate (c) being between about 1:0.7 to 1:1.5.

    摘要： In order to reliably form a coating layer on the interior surface of a primary lining such as an underground pipe, etc., in a short time and form a coating layer having a uniform thickness, a spray gun 62 is attached to a revolving ring 30 attached to a running truck 2, right and left drive wheels of the running truck 2 are respectively independently driven and controlled to moving the running truck 2 in a primary lining 90 while the revolving ring 30 is rotated at a steady peripheral velocity to blow out a coating material from the spray gun 62, whereby a homogenous coating layer is formed with a fixed thickness on the interior surface of the primary lining 90.
