The water in the bathroom is acidic because it combines with carbon dioxide and monoxide in the air to form acidic water, and this acidic water will penetrate the wall and leak out when the bathroom wall is poorly waterproofed. This acidic water then combines with the alkaline molecules in the cement, sand, and brick walls to form a cycle of acid-base neutralization and pressure release, which over time produces birch, also known as \u201clong white hair\u201d or \u201cwall cancer.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> (ii) Construction outside the bathroom has been successful or unsuccessful; the key is the material of the partition wall\u2014<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> (1) RC walls: The success rate is the highest, but you must first remove any long-haired paint and cement powder layers, and then follow the construction method in question 5 of this book to achieve a permanent result. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(2) Red brick walls: The success rate is second-best; the construction still follows the method described in question 5 of this book, but after a period of time, slight wall cancer with long hair may reappear.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> (3) Wall surfaces such as silicate board, plasterboard, lightweight cement (such as white brick ALC), etc., when constructed from the outside are bound to be ineffective and a waste of effort!<\/p>","protected":false},"excerpt":{"rendered":"<p>\u7b54\uff1a (\u4e00) \u6d74\u5ba4\u5167\u7684\u6c34\u6c23\u91cd\u3001\u6d74\u5ba4\u5916\u7684\u6c34\u6c23\u8f15\u3002\u800c\u6d74\u5ba4\u5167\u7684\u6c34\u6c23\u56e0\u7232\u8207\u7a7a\u6c23\u4e2d\u7684\u4e8c\u6c27 \u5316\u78b3\u3001\u4e00\u6c27\u5316\u78b3\u76f8\u7d50\u5408\u5f62\u6210\u9178\u6027\u6c34 [&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-8923","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\/8923","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=8923"}],"version-history":[{"count":0,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/posts\/8923\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/media?parent=8923"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/categories?post=8923"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/tags?post=8923"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
