Shin abin da ke faruwa na efflorescence a cikin turmi yana da alaƙa da hydroxypropyl methylcellulose?

Al'amarin na efflorescence shine: siliki na yau da kullun shine silicate, kuma idan ya ci karo da iska ko danshi a bango, silicate ion yana fuskantar wani maganin hydrolysis, kuma hydroxide da aka samar yana haɗuwa da ions na ƙarfe don samar da hydroxide tare da ƙarancin solubility (kayan sinadarai shine. Alkaline), lokacin da zafin jiki ya tashi, tururin ruwa yana ƙafe, kuma hydroxide yana haɗewa daga bango. Tare da ƙafewar ruwa a hankali, hydroxide yana haɓaka a saman simintin siminti. Da shigewar lokaci, ana ɗaga fenti na asali na ado ko fenti da sauran abubuwa kuma ba za su ci gaba da bin bango ba, kuma za a yi fari, bawo, da bawo. Ana kiran wannan tsari "pan-alkali". Don haka, ba shine ubiquinol da hydroxypropyl methylcellulose ya haifar ba.

Abokin ciniki ya ce wani al'amari: fesa grout da ya yi zai sami pan-alkali akan bangon kankare, amma ba zai bayyana akan bangon bulo da aka kora ba, wanda ke nuna cewa silicic acid da ke cikin siminti da ake amfani da shi akan bangon kankare gishiri mai yawa (da ƙarfi). alkaline gishiri). Efflorescence lalacewa ta hanyar evaporation na ruwa amfani da feshi grouting. Duk da haka, babu silicate akan bangon tubali da aka kora kuma babu efflorescence zai faru. Saboda haka, abin da ya faru na efflorescence ba shi da dangantaka da spraying.

1. An rage abun ciki na silicate na simintin siminti mai tushe.

2. Yi amfani da wakili na baya na anti-alkali, maganin ya shiga cikin dutse don toshe capillary, don haka ruwa, Ca (OH) 2, gishiri da sauran abubuwa ba za su iya shiga ba, kuma ya yanke hanyar pan-alkaline abu.

3. Don hana shigar ruwa, kar a yayyafa ruwa da yawa kafin a yi gini.

Maganin pan-alkaline sabon abu

Ana iya amfani da wakili mai tsaftacewa na efflorescence a kasuwa. Wannan wakili mai tsaftacewa shine ruwa mai ɗaukar hoto mara launi wanda aka yi da abubuwan da ba na ionic ba da sauran kaushi. Yana da wani tasiri akan tsaftacewa na wasu saman dutse na halitta. Amma kafin amfani, tabbatar da yin ƙaramin samfurin gwajin toshe don gwada tasirin kuma yanke shawarar ko za a yi amfani da shi.
