聚氨酯原料特点和使用注意事项
来源: 日期:2018-09-14 发布人:admin

关于聚氨酯原料特点和使用注意事项;你是否了解呢?我们今天来了解下吧;小编带你一起来浅谈;聚氨酯保温材料的主要原料之一是聚氨酯硬泡组合聚醚。聚氨酯硬泡组合聚醚又称白料,与聚合MDI共称黑白料。适用于建筑保温、太阳能、热水器、冷库、恒温库、啤酒罐、冷藏等需要保温保冷的各种场合。

About the characteristics of polyurethane raw materials and matters needing attention in use, do you know? Let's get to know about it today. Let's talk about it with you. One of the main raw materials of polyurethane insulation material is polyurethane rigid foam composite polyether. Polyurethane rigid foam combination polyether is also known as white material, and aggregate MDI is known as black and white material. It is suitable for building insulation, solar energy, water heater, cold storage, thermostat, beer tank, refrigeration and other occasions that need to be kept warm and cold.

一、聚氨酯原料特点如下:

1. The characteristics of polyurethane raw materials are as follows:

1、独特的隔热保温性能,节电效率高、环保;

1. Unique heat insulation performance, high efficiency and environmental protection.

2、重量轻,降低载荷;具优良的防水性能,保温、防水合二为一;

2, light weight, low load, excellent waterproof performance, heat preservation and waterproof.

3、设计简单、效率高、进度快、质量好、寿命长;

A1级防火保温材料

3, simple design, high efficiency, fast progress, good quality and long life.

4、无氟发泡,适应环境宽;

4, no fluorine foaming, adapt to the environment wide;

由于大型罐体保温层成型(特指浇注型)时无法设计闭模方式,在成型过程中无法产生必要的闭模挤压效果,因而处于半自由发泡状态成型的泡沫常会有不可避免的成型收缩性,如该收缩性较大或者不均匀会造成保温效果下降、外观不雅等现象,如何严控该收缩性是罐体配料、选材的至关重要的一环。

Due to the fact that it is impossible to design a closed die for the forming of the insulation layer of large tank, and the necessary closed die extrusion effect can not be produced during the forming process, the foam formed in the semi-free foaming state often has an inevitable forming shrinkage. If the shrinkage is large or uneven, the insulation effect will be reduced. How to strictly control the shrinkage of the tank is a crucial link in the batching and material selection of the tank.

二、聚氨酯原料使用注意事项如下:

Two. Matters needing attention in the use of polyurethane raw materials are as follows:

1、 发泡使用时最好调控料温在适当范围,以确保体系具有合适的反应性能和流动性;

1. When foaming, it is best to adjust the material temperature in an appropriate range to ensure that the system has appropriate reactivity and fluidity.

2、发泡时应严格依照使用说明要求确定白料与黑料比例,以确保体系的工艺性能和泡沫的各种基本性能不受影响;

2. When foaming, the ratio of white to black should be determined strictly according to the instructions, so as to ensure that the technological properties of the system and the basic properties of the foam are not affected.

3、请勿让材料与水分接触,在生产现场请注意适当通风。

3, do not let the material contact with the water, please pay attention to proper ventilation at the production site.
