industry: water property coating material

production product: water property 烤漆

: day 益严格 国家 environmental protection regulations and 实施, coating requirements 也越 越 high. coating not only need ensure good anti property can, high decoration property can, high property can, also need using/adopting property can good material and process, reduce property has machine material （VOC） 排放.

in recent years, water property its relatively is environmental protection formed separation, formed is coating material force 军. water property and solvent agent type versus ratio most large advantages is VOC排放 large large reduce. water property versus for solvent agent type tool has ring 境污染 small, high property, appearance property good and other advantages; versus for water property 漆 施工 requirements high, conductive property good, property high and other disadvantages.

quality requirements:

    严禁脱皮, 漏刷, 斑迹, 棕眼刮平, 木纹清晰, light and, light slip 无挡, good, 无流坠, 皱皮, color 一致, 无刷痕.

solution methods

    木材 water rear, water fiber tube/pipe and in micro 隙渗入, make its 膨胀变 large, 突出木材 surface, dry rear can 复原. therefore coating water property rear 会出现木纹突起, pellets, 生毛刺 and other phenomenon.

1, use wax 虫胶漆封闭木材 surface. this type of methods ratio water wet method good, remove can anti coating water property generate 起粒, long outer, also can increase 木材 层次感. is, due to 虫胶本身 color, 往往会 make belt/tape upper 淡淡 琥珀 color. 虫胶漆封底 for 旧漆面 and can can already by 油脂, demolding agent, has machine silicon combined material 污染 木材 surface separation has use, can anti coating water property generate shrink 孔, and other 施工弊病. coating process in if coating 装面, especially is 旧漆面 coating rear has shrink and phenomenon 时, scratch already coating water property 漆, abrasion rear use wax 虫胶漆封底, rear again coating water property 漆. 虫胶漆 is 虫胶 酒精 solvent liquid, can use coating or scratch coating method 施工. rear use 400# above 砂纸打 abrasion, again use or wet scratch 拭净打 abrasion 面, this can increase 面漆 附 force.

2, use can extrusion water wet scratch coating 木面, make surface separation lubricating wet, dry rear use fine 砂纸打 abrasion formed and pellets. rear coating 一道底漆, dry rear use 400# left right light light abrasion. for more 孔木材 need coating 两道底漆 rear again abrasion, this 时第一道底漆应 add 5%～10% water dilute rear again use.

water property 漆喷房施工 ring for spray coating quality has very large effect/influence, therefore meet/satisfy below/following conditions:

    （1）喷房亮 degree 明亮且 uniform;

    （2） temperature wet degree 适宜;

    （3）无灰尘;

    （4）良 good system;

    （5）良 good 文丘里 remove system;

    （6）完备 anti equipment.

     according to experience, water property need to good product quality, meanwhile meet/satisfy below/following conditions:

    （1）照 degree control in 750~1500lx;

    （2） temperature degree 22~26℃ is most 佳, versus for wet degree 55%~75%（65% most 佳）;

    （3）灰粒 control requirements 5μm is 1, 10μm is 0;

    （4）手工段 toward lower speed 0.2~0.4m/s, 自动段 toward lower speed 0.4~0.6m/s.

烘房 system technology features

运 use water property spray coating process workshop, in coating 烘房开始段都会 has 一 预烘 dry process. in this stage/phase temperature degree by add hot to 80℃ left right, to water separation function, rear again will temperature degree add hot to 170℃ left right, make film 彻底烘 dry. therefore this design, is is water property if rise temperature fast formed water separation fast, 而导致 orange peel and other defect 出现.

water property color spray coating formed rear, need through dry 烘房进行脱 water 处理, can formed “ wet wet ” spray coating process. according to experience, color water rate control in 90%~95% between, water large formed light, 发花, appearance and other defect, water low 则会造 formed and other defect.

1, due to water property main/primary formed separation is water, therefore water property ring system use material must is 不锈钢材 material.

2, water tool has high conductive property, therefore spray coating water property and spray coating solvent agent type use spray coating system has very large difference. is anti high pressure electrical 泄露至主循 ring tube/pipe 路, water property machine internal use 柱塞泵代替 gears 泵, will 喷漆回路 and ring tube/pipe 路断开, anti 止危险发生.

3, 冬季施工室 inner engineering in conditions lower 进行, room temperature maintain 均衡, low 于+10 degree, 且不 突然变化, 应设专人 negative temperature and 开关门窗, 以利通风 troubleshooting wet gas, 夏季施工时应 in coating material in add water, anti 止受潮泛白. water property 清漆施工 need maintain 通风. need anti 止霉变.

4, coating generally surface use 200#砂纸初步打 abrasion rear again use 600#砂纸打 abrasion, make its light slip. fine parts can use 600#砂纸打 abrasion. fine 砂纸打 abrasion make 木纹紧密, decrease/reduce 木纹起粒 phenomenon.
