And what is the best construction method?"},"content":{"rendered":"<p class=\"wp-block-paragraph\">Answer:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(1) The most commonly used method on the market today is the five-layer FRP construction method (which is a three-layer unsaturated polyester coating with two layers of glass fiber mesh sandwiched in between). The waterproof performance and acid-base resistance of this method are beyond question. The problem is that FRP itself is a steel-based waterproof paint; is it really suitable for use in swimming pools? I really have my doubts (in case of subsidence and earthquakes, won\u2019t its waterproof performance be affected?). Moreover, the considerations of occupational safety and environmental protection\u2014the gases emitted by unsaturated polyester during the coating process are carcinogenic; the process of laying fiberglass threads can easily cause itching and irritation on workers\u2019 skin; and the worst part is that the fine fiberglass threads could be inhaled by workers into their lungs\u2014these are completely toxic substances that cannot be excreted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><br>(ii) According to my many years of experience, the best construction method is super-hardened polyurethane (PU) and the oil-based PU series with a higher unit price; the surface is then dried and sprayed (the floor is first coated with a thin layer of stone, and the walls can be painted with elastic cement after the PU has hardened the next day). The most important thing is that the wall surface must be coated with non-dripping polyurethane; the thickness must be at least 2mm; otherwise, there is a high risk of surface polyurethane peeling off or wrinkling after the pool is put into use.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u7b54\uff1a (\u4e00) \u76ee\u524d\u5e02\u5834\u4e0a\u6700\u5e38\u63a1\u7528\u7684\u662f\u4e94\u76aeFRP\u5de5\u6cd5(\u4e5f\u5c31\u662f\u4e09\u5c64\u4e0d\u98fd\u548c\u805a\u8102\u5857\u88dd\uff0c\u4e2d\u9593\u593e\u5169\u5c64\u7684\u73bb\u7483\u7e96\u7dad\u7db2)\u3002\u9019\u7a2e\u5de5 [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[24],"tags":[70],"class_list":["post-8902","post","type-post","status-publish","format-standard","hentry","category-100qa","tag-qa"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/posts\/8902","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/comments?post=8902"}],"version-history":[{"count":0,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/posts\/8902\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/media?parent=8902"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/categories?post=8902"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/tags?post=8902"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
