Microbiocidal mixtures

Algicide combination

Continuous process for producing unidirectionally reinforced composite materials by impregnating a continuous reinforcing fiber strand with a thermoplastic matrix in an impregnating bath containing a dispersion of a thermoplastic powder by measuring the width of the strand leaving the impregnating bath and using this measured value for regulating the polymer concentration in the impregnating bath.

Production of composites from polymer powder dispersions

The present invention relates to a storage-stable aqueous solution of one or more compounds of the general formula I ##STR1## wherein Y, R and R.sup.1 are as defined in claim 1, which comprises a noble metal ion.

Storage-stable aqueous solutions of isothiazolin-3-ones

Preparation of biocidal polymers and copolymers based on free radical-polymerizable and copolymerizable ethylenically unsaturated monomers containing monomer units composed of BCM salts of ethylenically unsaturated carboxylic acids, sulfonic acids or phosphonic acids, solutions thereof and preferably aqueous dispersions thereof. Processes for their preparation and their use as fungicidal and algicidal impregnating agents, paints and finishing agents for scumbles and dispersion paints providing protection against blue staining on wood, for synthetic resin renderings, for exposed concrete paints and for textile finishing agents.

A process for the continuous production of laminated sheet materials of thermoplastic polymers, reinforcing fibers and metals, in which endless sheets of reinforcing fibers, thermoplastic polymers and metals are combined in layers and the layers thus combined are continuously exposed for 0.1 to 10 minutes to a pressure of 0.5 to 50 bar at a temperature 20.degree. to 150.degree. C. above the melting temperature of the thermoplastic polymer.

Process for the continuous production of laminated sheets

Liquid preservative compositions which are particularly useful for plastics dispersions and secondary products prepared therefrom are disclosed. These compositions comprise mixtures of 1,2-benzisothiazolin-3-one or a salt thereof and at least one alkyl(polyaminoalkyl)glycine compound.

The present invention relates to the use of methylthiocyclopropylamino-tert.-butylamino-1,3,5-triazine (Mctt) as a microbicidal agent for the treatment of concrete roof tiles.

Use of a microbicidal agent for the treatment of concrete roof tiles

Process for the manufacture of continuous moulded bodies from structures of reinforcing fibres impregnated with thermoplastic plastics, wherein a structure of reinforcing fibres is passed through a melt of the thermoplastic at a pressure of 1 to 800 bar for a length of at least 300 mm and a device for carrying out the process.

Granulate-form agglomerates of pulverulent rubber chemicals having a maximum primary grain size of 500 .mu.m , an active substance content of at least 90% by weight and an assessment (a) in the intermixing test of at the most 1.5, (b) in the dust proportion test of at the most 10, (c) in the fine material proportion test of at the most 5 and (d) in the falling test of at the most 70, as well as a process for its production characterized in that the pulverulent rubber chemicals of a maximum primary grain size of 500 .mu.m are mixed with a moistening agent and/or a lubricant and are supplied to a double shaft screw granulator with forced conveyance, in which the spacing between the nozzle plate and the vertically cut screw ends is between 0 and 1.6 mm, whereby the compression ratio K.sub.D is between 1:6 and 1:1.5 and the ratio of nozzle channel length to nozzle channel diameter is between 1 and 6, and whereby the specific granulation work is from 2 to 40 Wh/kg, the rubber chemicals are forced axially through a nozzle perforating plate, the issuing strands are severed or are allowed to break-off and are then dried.

Granulate-form powder agglomerates of pulverulent rubber chemicals and a

The shredding of fibres in the form of bands or strands to staple fibres with short staple length and fibre velocities of up to 6,000 m/min is attained by winding the fibre tow around a cutting ring with adjustable blades and cutting up the fibre tow by pressure rollers pressing radially on the winding. The feeding of the fibre tow is synchronized with the pressure rollers, as these rollers are fixed in supporting discs which rotate above and below the cutting ring with the same velocity as the depositing nozzle.

Process and apparatus for shredding fibre tows into staple fibres

Running threads are fed through a heating chamber containing saturated steam by means of specially designed shutters. The thread is heated over a short section of the path so that the heating apparatus takes up little space even at high thread speeds.
