Description

PBTCA has structural features of both phosphoric acid and carboxylic acid group, which enable it with excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is better then organophosphonic acid. It is the stabilizer for zine salt in water. It can be chelated with Ca2 �Mg2 and Zn2 to form stable chelating compounds. It is an efficient corrosion and scalt inhibitor. 4.Application: PBTCA can be used in situations of high temperature, high hardness, high atkali circulating cooling water system and oilfield refill water system as scale and corrosion inhibitor. It is usually used together with carboxylic acid coplymer. PBTCA has no toixicity and enveronmetal polution. 5.Specification: (1).Appearance:Light yellow transparent liquid (2).Active content(%):�*0 (3).Phosphorous acid (as )%:�0.8 (4).Phosphorous acid (as )%:�0.5 (5).Density(*0�)g/cm3:�1.*5 (6).PH(1% Solution):�2
