渗透型密封固化剂的性能特点和油漆固化剂的作用

渗透型密封固化剂的性能特点:可以进步,凝土、石块、灰泥、混凝土等产品的全面性能;混凝土外表硬度33.3%和密度,从而减少重型机械对空中的毁坏;抗弯强度、着色力和其他资料的粘合强度。可以避免,各种有毒气体的扩散;50%到90%的内部氯化物;铁锈和水性污染物的污染,从而降低维护本钱;青苔,苔藓和其它生物在外表生长,从而消弭了定期肃清的必要,可以阻止,塑料热收缩、裂、卷曲、起皮以及隔裂,内部螺纹钢筋的腐蚀,碱性风化,酸雨或者污染物的浸透招致混凝土的变色、蜕变,可以抵御,最多98%的水及水蒸气压力,高速公路和海上的各种氯化物,油渍,气体,酸性物质,溶剂,细菌和紫外线的腐蚀,由于温差变化招致的剥离/膨缩/散裂。

Performance characteristics of immersion sealant: it can improve the overall performance of products such as condensate, stone, mortar and concrete; concrete surface hardness 33.3% and density, thereby reducing the damage of heavy machinery to the air; flexural strength, colouring strength and bonding strength of other materials. It can avoid the diffusion of various toxic gases; 50% to 90% of internal chlorides; the pollution of rust and water pollutants, thereby reducing maintenance costs; the growth of moss, moss and other organisms on the surface, thus eliminating the need for regular cleaning, which can prevent plastic from shrinking, cracking, curling, peeling and cracking, corrosion of internal rebar, alkaline weathering, acid rain or fouling. Immersion of dyes causes discoloration and metamorphosis of concrete, which can resist up to 98% of water and vapor pressure, various chlorides on expressways and seas, oil stains, gases, acidic substances, solvents, bacteria and ultraviolet rays, and exfoliation/expansion/spallation due to temperature variation.

油漆固化剂的作用:据理解,固化剂又为名硬化剂、熟化剂或变定剂等,也是一类促进或控制固化反响的物质或混合物。树脂固化是经过缩合、闭环、加成或催化等化学反响,使热固性树脂发作不可逆的变化过程,固化是经过添加固化(交联)剂来完成的。固化剂按用处可分为常温固化剂和加热固化剂。环氧树脂高温固化时普通性能优秀,但是在土木建筑中运用的涂料和粘接剂等由于加热艰难,需求常温固化、中温固化剂和高温固化剂,要以被着体的耐热性以及固化物的耐热性、粘接性和耐药品性等为基准来选择。选择重点为多胺和酸酐。由于酸酐固化物具有优秀的电性能,所以普遍用于电子、电器方面。脂肪族多胺固化物粘接性以及耐碱、耐水性均优秀。芳香族多胺在耐药品性方面也是优秀的。由于氨基的氮元素与金属构成氢键,因此具有优秀的防锈效果。胺质量浓度愈高,防锈效果愈好。只要对这些原料、技术停止准确把握,并慎重对其质量停止控制才干消费出高质量的固化剂。

The role of paint curing agent: It is understood that curing agent, also known as hardener, curing agent or stabilizer, is also a kind of material or mixture that promotes or controls the curing reaction. Resin curing is a process of irreversible change of thermosetting resin through chemical reactions such as condensation, closed-loop, addition or catalysis. Curing is accomplished by adding curing agent. Curing agents can be divided into room temperature curing agents and heating curing agents according to their uses. Epoxy resin has excellent general properties when cured at high temperature, but the coatings and adhesives used in civil buildings need room temperature curing, medium temperature curing agent and high temperature curing agent because of the difficulty of heating. They should be selected on the basis of the heat resistance of the implant and the heat resistance, adhesion and resistance of the cured material. The selection focuses on polyamines and anhydrides. Because anhydride cured products have excellent electrical properties, they are widely used in electronic and electrical fields. Aliphatic polyamine cured products have excellent adhesiveness, alkali resistance and water resistance. Aromatic polyamines are also excellent in drug resistance. Because the nitrogen element of amino group forms hydrogen bond with metal, it has excellent antirust effect. The higher the concentration of amine, the better the anti-rust effect. As long as these raw materials and technologies are accurately grasped and their quality is carefully controlled, high quality curing agents can be consumed.
