1、 The three core elements of performance: ammonia value, viscosity, and reactivity
The performance of amino silicone oil is directly controlled by three major parameters: ammonia value, viscosity, and reactivity. These three indicators are like a "molecular ID card", jointly determining its final effect in industrial applications. Mastering the intrinsic correlation of these parameters is the key to breaking through the bottleneck of traditional material applications.
1. Ammonia value: the chemical code for softness
The ammonia value is the millimoles (mmol/g) of 1mol/L hydrochloric acid consumed by 1g silicone oil. This seemingly simple titration data hides a mystery:
·The range of 0.2-0.6 is the golden value band for fabric finishing, and exceeding this range can cause the fabric to become sticky or hardened
·Japanese experimental data shows that amino silicone oil with an ammonia equivalent of 2000 can significantly reduce the friction coefficient of polyester fabrics from 0.267 to 0.10
·Be wary of the "high ammonia trap": when the ammonia value exceeds 0.8, the probability of fabric ash absorption increases by 40%
2. Viscosity: Visualization expression of molecular weight
By using the viscosity molecular weight positive correlation law, engineers can determine without the need for complex instruments:
·For every 1000mm ²/s increase in viscosity, the film thickness increases by 15-20nm (verified by AFM atomic force microscopy)
·When the molecular weight distribution index (PDI) is less than 1.2, the smoothness of the fabric surface is improved by 30%
·Special case: In the field of automotive polishing, amino silicone oil with a viscosity of 8000mm ²/s can form a 5 μ m self-healing film layer
3. Reactivity: precise manipulation of chemical bonds
The difference in the proportion of terminal methyl/methoxy groups directly rewrites the fate of materials:
·Amino silicone oil containing 15% methoxy groups, with a 3-fold increase in bonding strength with cotton fibers (confirmed by XPS surface analysis)
·In the modification of epoxy resin, reactive groups increase the interfacial shear strength from 8MPa to 22MPa
·In the field of medical textiles, controllable reactivity ensures that the loading rate of antibacterial agents is greater than 95%
2、 Six major application scenarios for solving industry pain points
1. Textile Revolution: Technological Iteration from Laboratories to Production Lines
·Dynamic friction coefficient<0.15: Cashmere sweaters treated with fourth generation microemulsion technology have exceeded the 50 wash resistance threshold
·High temperature resistance breakthrough: After introducing polyether modification, the flame retardant rating of workwear has been increased from LOI 26 to LOI 32
·Cost control: Nano particle size (<50nm) technology reduces the amount of additives by 40%
2. The invisible champion in the field of demolding
In the manufacturing of automotive tires:
·The demolding efficiency has been increased by 70%, and the mold cleaning cycle has been extended from 8 hours to 72 hours
·The surface roughness Ra value decreased from 1.6 μ m to 0.4 μ m (measured by a white light interferometer)
3. The protracted battle of polishing agents
·Metal polishing agent using triple crosslinking technology, with weather resistance extended from 1 week to 3
·Comparative experiments show that the hardness of amino silicone oil based polishing film reaches 3H, which is 2.5 times that of traditional wax
4. Cross border breakthrough in resin modification
·The impact strength of epoxy resin has increased from 8kJ/m ² to 22kJ/m ² (ASTM D256 standard)
·The temperature resistance range of polyurethane has been expanded to -50 ℃~180 ℃, breaking through the limit of traditional materials
5. Technological upgrades in personal care
·Shampoo containing 0.5% amino silicone oil improves combing performance by 60% (tensile test data)
·Toothpaste anti staining experiment: After soaking coffee for 72 hours, the color difference value Δ E is less than 1.5 (CIE Lab standard)
6. Ice and fire test of environmentally friendly coatings
·The water-based lotion remained stable after 10 freeze-thaw cycles, and the VOC emission was reduced by 90%
·In ship coatings, the salt spray resistance time has been extended from 2000h to 5000h
3、 The fourth generation amino silicone oil technology has achieved three major breakthroughs:
1. Particle size control: particle size of microemulsion ＜ 50nm (dynamic light scattering method verification)
2. Environmental upgrade: D4 residue<0.01% (GC-MS detection limit)
3. Function integration: Antibacterial rate>99.9% (ISO 20743 standard)
Industrial case: After adopting a new type of amino silicone oil, a medical textile enterprise:
·The product has passed the EN 14126:2003 biological pollution protection certification
·The energy consumption of the production line has been reduced by 25%, and the COD value of wastewater has decreased by 60%
The future battlefield has extended to the field of molecular design: through quantum chemical simulation, intelligent amino silicone oil with self-healing function has been developed, ushering in a new era of materials science.
