Use concentrated polytetrafluoroethylene dispersion as the base material |
Coating plasticization process Spray the prepared paint on the surface of the sample and put it in a constant temperature drying oven, and heat it to (60;80)¡ëC (not more than 80¡ëC, otherwise the coating will bubble due to excessive water evaporation), and keep it for 20 minutes; Then increase the temperature to 120¡ëC and keep it for 20 minutes.
Molybdenum disulfide 2.3 NDZ-311W 0. The steps are as follows:
(1) Weigh the required concentrated PTFE dispersion and stir at high speed;
(2) Add the required amount of tin bronze powder, molybdenum disulfide, chromium trioxide, polyphenylene sulfide resin, and stir at high speed;
(3) Add titanate coupling agent NDZ-311W slowly and stir;
(4) PTFE BBQ Mat Slowly add Foamaster III defoamer and stir;
(5) Slowly add Levelling 620 associative levelling agent and stir;
(6) Slowly add the film-forming aid alcohol ester twelve and stir.
Preparation: Use concentrated polytetrafluoroethylene dispersion as the base material, and add fillers (the fillers are dried through a 600-mesh screen) and additives. Levelling620 0.006 Alcohol ester twelve 0.7 Bronze powder 6.
Formula 1 (Single-layer Teflon coating) Polytetrafluoroethylene concentrated dispersion 100 Chromium trioxide FoamasterIII 0. Take it out and put it in a box-type resistance furnace for plasticization.Polyphenylene sulfide.
