It is a homogeneous mixture of a water-soluble phenol-formaldehyde prepolymer brand FRV-1 with the product OP-7 (surfactant) and aluminum powder brand PAK-4.
Heating of the raw material was carried out by the contact method when the container with the prepolymer was immersed in a heated liquid (water) with constant stirring of the prepolymer and control of temperature indicators. 3 Results and Discussions For the beginning of research, it was necessary to determine the effect of the starting components and their content on the main properties of phenolic foams.
And also, the toxicity of phenolic foam is reduced by removing free phenol and formaldehyde monomers together with water vapor from the foaming composition.

The BCIRA Test principle has been applied for purposes of designing a Polish professional DMA Device named by its designers a device for testing the high-temperature phenomena in casting cores [6, 7].
The effect of free water contents and the water chemically bounded in inorganic resin SE on the growth of substitutional specific heat c is also clearly evident.
The sources exist until water evaporation from the sample.

Because there is no professional equipment and consumables for vacuum sealing method, the vacuum packaging machine in the food industry is used in this study.
The sealed specimen are submerged in the water, and then weigh the quality in the water; 5.
To remove the samples from the water, untied bags, reweighing specimens dry weight.

Parallel to this were the engineering requirement of developing a stronger general and specific vocabulary, written/oral English in active ways that integrated and generated ideas in technical areas (water, chemistry, biology and ecology etc).
Role-playing and simulation were very important and included: simulated professional teamwork, work related technical problem solving tasks and/or workplace situations in activities like Debating and Theater Forum (based on Experiential Learning).
Valentukeviciene is from the Water Supply and Management Department was the Project's Manager, Edita Baltrenait÷, is a Doctoral Student (Environment Protection Department) was the Project's Assistant Administrator.

Nowadays, water-logging in cities usually occurred in large recurrence interval, so that many experts suggest that annual maximum value method is more applicable.
It isnecessary to evaluate the storm intensity formula, It is reasonable that evaluating storm formula, original stormformula for whether itis still applicable for the overall design plan of the city, the drainage professional planning and drainage engineering.

Other applications in the raw material of humidity sensors [4] and professional grade ferrites [5] have also been reported.
All chemicals were reagent grade and dissolved in de-ionized water separately.
After aging in the mother liquor at room temperature, the brown precipitates subsided easily was washed several times with de-ionized water by a decantation process.
The collected gels were washed with a diluted aqueous solution of hydrazine to prevent the precursor from being oxidized before aging and then washed with de-ionized water.

Referring to GB/T 4897.1~4987.7-2003《Flakeboard》test, Board performance: density is 0.757 g/cm3, water ratio is 7.851%, IB is 0.35 MPa, MOR is 21.6 MPa, elasticity modulus is 3 031 MPa, Water absorption and thickness swelling in 2h is 3.049%. 2) Base material sanding.
To the degree of simulation, author mainly through asking some professional staffs of engineering department in coating factory to judge the simulation quality, compared to other special coatings, crackle-simulated coating is good at simulated effect, and give the furniture a feeling of back to nature, which is worth being vigorously pushed in modern house.
The cost of furniture coating including cost of coating, handling cost, human cost, equipment loss, water and electricity costs, other material costs and so on[6].
