products are designated as Alkaline Copper Quat (ACQ) which are standardized under American Wood Protection Association (AWPA) U-1. ACQ is recognized for use in above ground, ground contact – general use, heavy duty and extreme duty applications to resist attack by fungal decay and subterranean termites including Formosan termites.

2020年10月15日 · The objective of this study is to determine the effects of alkaline copper quaternary (ACQ) treatment on the surface quality and bonding performance of four Malaysian hardwood species, namely batai, sesenduk, rubberwood and kedondong.

In this study, the effects of the ACQ preservative on the bonding strength of aqueous polymer isocyanate (API) bonded Masson pine joints and on the adhesive penetration into wood was investigated. Masson pine wood samples were treated with ACQ of three concentrations (0.1%, 0.5%, 1.0%) and then bonded with the API adhesive.

2016年1月1日 · ACQ treatment is a water based wood preserving method. ACQ is made up of copper, bactericide and fungicide, which ensures wood resistant to biological attack. A quaternary ammonium compound (quat) acts as biocide to increase the tolerance of treated timber to copper-resistant bacteria and fungi, in addition to perform as insecticide (Lebow, 2004).

2018年10月30日 · Commercial alkaline copper quat-type D (ACQ-D), thermosetting phenol–formaldehyde (PF) resin with varying concentrations, and urea–formaldehyde (UF) resin were used to improve decay resistance of low-grade fastgrowing poplar.

Alkaline copper quat (ACQ) and copper azole (CA-B), the most prominent substitutes for chromated copper arsenate (CCA), are difficult to bond consistently. Using a phenol-resorcinol-formaldehyde (PRF) adhesive formulated for bonding to CCA-treated wood, we exam ined the bonding of southern yellow pine treated with CCA, ACQ, or CA-B.

Ammonical Copper Quat （ACQ）是由二价铜 、烷基铵化合物、氨或胺和水按一定比例组成的一种木材防腐剂，它是由美国拉波特化学专用产品公司（Chemical Specialties Inc (CSI)-Laporte，现名Chemical Specialties (…

ACQ木材防腐剂能有效地杀灭和抑制真菌、霉菌（变色菌 黑曲霉 、木材腐朽菌 白腐菌 、 褐腐菌 和 宛氏拟青霉）、蛀虫和白蚁等，能与木材纤维牢固的结合在一起，不易流失，故能对木材起到长期保护的作用，经ACQ防腐剂处理的木材使用寿命显著延长。 经ACQ木材防腐剂处理后的木材呈绿色，在户外使用一段时间后会慢慢变为暖棕色，不影响油漆和着色。 不降低木材绝缘性能，不降低力学强度。 用ACQ防腐剂处理后的木材，其主要成分不易从木材中流脱，所以ACQ防腐剂 …
