(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

原材料的国产化。国内厂家为保证单组分聚氨酯密封胶的产品质量，绝大部分采用了进口的原材料，由于价高及供货期的问题，竞争力受到一定影响材料利用率。该种单组分聚氨酯密封胶采用聚氨醋管材或棒材经数控加工中心切削加工而成，所以较原来的浇注模压工艺相比，材料利用系数大大降低，一则提高了成木，二则由于切削下来的废屑没有什么再利用价值，对环境造成污染。聚氨醋管材或棒材的质量。管材或棒材是单组分聚氨酯密封胶的原材料，所以管材或棒材的性能和稳定性对单组分聚氨酯密封胶的质量产生直接的影响。尽管管材或棒材选用的预聚体来自国外公司，扩链剂也是国内的顶级产品，但聚氨醋弹性体浇注机是由国内生产，不免在质量的稳定性上有所担忧。现在可以放心的是国内聚氨醋弹性体浇注机厂家也充分认识到该问题的严重性，已在原有的基础上进行了重大的改进，如计量泵选用进口产品，混合室吸收国外先进技术，系统控制由西门子公司设计。改进后的聚氨醋弹性体浇注机的工作稳定性大大提高，有力地促进了该种单组分聚氨酯密封胶质量的提高，保证了单组分聚氨酯密封胶品质的稳定性。

聚氨醋管材或棒材的检验。目前厂家对聚氨醋管材或棒材的检验仅限于外观，内部质量的检验还没有先进手段，致使加工过程中产品的报废率偏高，影响生产效率。因此研发聚氨醋管材或棒材的检验设备十分必要，望能引起业界的重视。

笔者建议采用数控加工中心加工制造单组分聚氨酯密封胶的厂家走出只加工煤矿用液压支架单组分聚氨酯密封胶的独木桥，在更大的单组分聚氨酯密封胶市场上进行探索和搏击，走出一条各具特色的路子来。http://www.sdyuantai.com/
