A1级防火保温材料选购要遵照的原则

Principles to be followed in selecting and purchasing grade A1 fire-proof and thermal insulation materials

1、应尽量选择涂料外饰面体系的原则

1. The Principles of Choosing Paint Exterior Decoration System as far as possible

采用涂料外饰体系即便发生裂痕也比拟直观,有利于对裂痕的控制。选择粘贴面砖外饰面该如何避免面砖饰面开裂:

The use of coatings exterior decoration system is more intuitive even when cracks occur, which is conducive to the control of cracks. How to avoid the cracking of the exterior decoration of the facing bricks when choosing the paste facing bricks?

整集体系必需经过抗震实验、耐候性实验、火反响性实验等大型实验验证。外保温外饰面粘贴面砖体系满足体系粘结平安性、辅佐机械锚固平安性、柔性释放应力平安性、耐候及防火平安性等综合功能。钢丝网架外保温体系饰面粘贴面砖时,用传统水泥砂浆找平的单网构造具有较大不合感性(荷载大、易开裂),外表受正负风压、热胀冷缩、干缩湿胀均爲双向受力,应采用膨胀率小的轻质砂浆找平并采用双网结构,完成柔性突变、加重荷载、添加抗裂性。

The whole system must be verified by large-scale experiments such as seismic test, weatherability test and fire response test. External thermal insulation and exterior decorative facing brick system meets the comprehensive functions of system bonding safety, assistant mechanical anchoring safety, flexible stress release safety, weather resistance and fire safety. The single-net structure leveled by traditional cement mortar is not susceptible to large load and easy cracking. The external surface is subjected to positive and negative wind pressure, thermal expansion and cold contraction, dry shrinkage and wet expansion. The light mortar with small expansion rate should be leveled and double-net structure should be adopted to complete flexible mutation, increase load and add crack resistance.

2、外墙保温体系供给商应对体系资料成套供给的原则

2. Principles of Suppliers of External Wall Insulation System for Complete Supply of System Data

外墙外保温是一个无机全体,组成体系的各相关层应协同作用,不只要求柔性突变,而且应有一定的相容性、协异性,构成一个复合全体。因而,外墙外保温体系应由体系供给商成套供给,以保证体系资料的婚配性及抗裂技术道路的完成,有利于明白工程质量的责任。

External wall thermal insulation is an inorganic entity. The relevant layers of the system should cooperate, not only require flexible mutation, but also have certain compatibility and covariance to form a composite entity. Therefore, the external wall thermal insulation system should be supplied by the system supplier, in order to ensure the matching of the system inion and the completion of the anti-cracking technical road, which is conducive to understanding the responsibility of the project quality.

3、增强保温截止部位材量变换处的密封原则

3. Sealing Principle of Enhancing the Change of Material Quantity in the Cut-off Part of Heat Insulation

在保温层与其它资料的材量变换处,由于这些材质的密度相差过大,这就决议了材质间的弹性模量和线性收缩系数也不尽相反,在温度应力作用下的变形也不同,极容易在这些部位发生面层的裂痕。同时还应该思索这些部位的防水处置,避免水份侵入到保温体系内,防止因冻胀作用而招致体系的毁坏,影响体系的正常运用寿命和体系的耐久性。

Because the density of these materials is too different from that of other materials, the elastic modulus and linear shrinkage coefficient are not the same, and the deion is different under the action of temperature stress. It is very easy to crack the surface layer in these parts. At the same time, the waterproof disposal of these parts should be considered to avoid water intrusion into the insulation system, prevent the damage of the system caused by frost heave, and affect the normal service life and durability of the system.

4、应充沛思索各层资料的相容性及婚配性原则

4. Consideration should be given to the compatibility of data at all levels and the principle of mating

由于外保温体系是由多层资料复合构成,就抗裂功能来说,除应思索各层资料本身功用性外还应充沛思索资料的相容性及婚配性。

As the external thermal insulation system is composed of multi-layer data, in terms of crack resistance function, we should consider not only the function of each layer of data itself, but also the compatibility and marriage of data.
