The structure and morphology of pearl cufflinks

value: Keep the other reaction conditions unchanged, by dropping hydrochloric acid or ammonia changes the pH value, the experimental results shown in Table 4.1: Table 4.1 pH value of sol generated; mpH of the experimental phenomena; Sol 9 rapidly generated, time of 10s sol color to yellow and uneven distribution of Gelation time 5min, to generate light yellow sol, the viscosity moderate. The cufflinks can play a good play to desalt the color of the skin.  Gelation time 15min to generate light yellow sol, the viscosity of the system is small. The two gel time for 22min to generate light yellow sol and contains a small amount of small bubbles. A generated light yellow sol, sol containing a large number of bubbles. Be able to tell from the above experimental phenomena and results:
pH value can not be too large, that the solution should not be alkaline, otherwise it would sol rapid condensation and the uneven distribution, resulting sol is difficult to uniformly attached to the surface of pearl cufflinks. [Ti (OH) 2] 2 + → of Ti4 + +2 OH-(4-1). Principle such as (4-1), alkaline increases the concentration of OH-greatly increased, the reaction to accelerate in the opposite direction, causing the gel to generate excessive. the pH value can not be too small, so that the generated nano-titanium dioxide film, because the acid is too strong, resulting in erosion of the surface of pearl cufflinks. The white people can choose the metal jewelry and cufflinks with precious stones, beads and carved shell jewelry.
The use of sol - gel (Sol-Gel) Preparation of technical and special forming process, intermittent copolymerization technology and resin phase formation process technologies such as preparation of anti-environmental study of erosion durable pearl cufflinks; the composition of the sol, the pH value, viscosity, gel time; pearl cufflinks in the sol in the appropriate conditions and timing of the reaction, the reaction temperature, reaction time and other conditions; After the reaction, the basic treatment processes, drying, temperature, time, etc.; When in evening wear, you can wear stones or diamond jewelry and cufflinks while casual wear paired with personalized jewelry or ethnic cufflinks.
By use of different basic raw materials, initiator and solvent control of temperature, pH value, time to consider the pearl cufflinks shape, size, surface state (roughness, porous morphology, size, distribution, etc. study) the impact of the performance of pearl cufflinks; Step two: the relationship between the microscopic structure of pearl cufflinks, surface state, as well as their modified material. cufflinks with clothing is the best V-neck, round neck, followed by relatively large and the fitted high collar. Using optical microscopy, Raman spectroscopy, infrared spectroscopy and other detection technology before and after modification the structure and morphology of pearl cufflinks.
Samples of any size, shape, transparency, can be laser light can be used to measure directly. Due to the smaller diameter of the laser beam, and can be further focused, and therefore extremely small amount of sample can be measured. The biggest drawback of Raman spectroscopy studies of polymer samples is fluorescent scattering, with the impurities of the sample. But the use of Fourier transform Raman spectrometer can overcome this shortcoming. Just before to wear any kind of jewelry and cufflinks, we must be sure the dress we wear is nude clothing is or not.
I have better mechanical strength and toughness after modified optimization more prominent anti-acid, anti-environmental erosion, even under the strong irradiation of UV, not back to yellow, do not cause a radical reaction nor oxidative aging reaction. Silicone resin protective agent due to its excellent permeability and weather resistance are many stone protection experts as the most promising protective material one. Besides, the cufflinks have smooth fabric and simple design but an ordinary clothing.  Monomer has a good ability to penetrate the penetration depth of up to 50mm, but also because of its degree of polymerization can be adjusted.
