The result showed that the best technological condition of chemical composition coating is as follows: ρ (SiC)=10 g·L~(-1), φ(PTFE)=0.8%, pH=4.6～4.8, temperature of bath=88 ℃～89 ℃, heat treatment=300 ℃, the time=1 h.
The optimum technological condition recommended for processing 6100 M comprised cylinder temperature of 180-210 ℃, head temperature of 200-210 ℃, die temperature of 200-220 ℃ and melt temperature of 200-220 ℃.
The experiment was carried out to investigate the technological condition of heat-dehydration with L. barbarum L. By the experiment, it is sure that the mixture of 0.04% Zn(CHCOO)2 and 0.02% Na2SO3 is the best green protection reagent and soakage in the solution of 0.3% CaCl2 for 20 min can keep the quality of texture.
Synthesis and Choice of process condition for antistatic agent C_(11)H_(13)CONH(CH_2)_3N~+(CH_3)_2 CH_2COO~- have been described and its structure has been estabeished by means of IR、MS、NMR. The results show that structure of the product synthesized is in agreement with above-mentioned formula.
By selection of suitable polymer and process condition of spinneret orifice 0.13 mm, spinning temperature 296 ℃, quench air velocity 0.35 m/s, spinning speed 2 750 m/min and filament collection position 600~700 mm, the fine denier POY with strength tenacity 2.48 cN/dtex, elongation at break 127.6 % was obtained.
It was found that the character of conductivity decay in a photoreceptor after positive or negative corona charging of its outer surface depended on the technological conditions of substrate pretreatment.
Using this method makes it possible to substantiate the choice of the optimal design of contact units in cascade pneumatic classifiers for various technological conditions.
Phase composition of Ti-C Films obtained under the technological conditions of diamond formation at a carbon content of above 50
Thin (6-12 nm) epitaxial MnAs films were MBE-grown on Si(111) substrates under different technological conditions.
The electrophysical and photoelectric properties of the films depend on the technological conditions of growth and are determined by states at intergrain boundaries.
