A cikin yanayin da ke da zafi mai zafi da ƙananan zafi, danshi na putty foda yana da sauƙi don ƙafewa, yana haifar da bushewa da sauri kuma yana tasiri tasirin ginin.
A lokacin aikin gine-gine, ya kamata a kiyaye yanayin zafin jiki da yanayin zafi mai kyau kamar yadda zai yiwu don hana putty foda daga rasa ruwa da sauri. Daidaitaccen kula da zafin jiki da zafi na yanayi kuma zai iya inganta riƙewar ruwa a kaikaice.
6. Ƙara wakili mai riƙe ruwa
Baya ga HPMC, ana iya la'akari da sauran abubuwan kiyaye ruwa a cikin foda, kamar wasu polymers, polyvinyl barasa, da dai sauransu. Wadannan magungunan ruwa na iya kara inganta yawan ruwa na putty, tsawaita lokacin ginawa, da kuma hana ma'adinan daga bushewa da tsagewa da sauri.
Koyaya, lokacin ƙara wakilai masu riƙe ruwa, ya zama dole a kula da dacewarsu tare da HPMC don tabbatar da cewa babu wani mummunan halayen da ya faru ko ya shafi aikin ginin putty.
7. Yi amfani da fasahar sarrafa zafi
A wasu lokatai na musamman, ana iya amfani da fasahar sarrafa zafi don ƙara haɓaka riƙewar ruwa na putty foda. Misali, yin amfani da sinadarai masu rufe ruwa ko kayan aikin humidification na iya yadda ya kamata ya rage asarar ruwa na putty yayin gini, kula da damshin jigon sa, ta yadda zai tsawaita lokacin gininsa da kuma inganta kiyaye ruwa.
Riƙewar ruwa na putty foda za a iya inganta yadda ya kamata ta hanyar zaɓar nau'in daidaiHPMC, ƙara yawan adadin ƙarawa, haɓaka ƙirar ƙira, haɓaka tsarin haɗuwa, sarrafa zafi da zafin jiki na yanayin gini, da sauran matakan. A matsayin wani muhimmin abu na putty foda, haɓakar ruwa na HPMC ba zai iya inganta aikin ginin ba kawai, amma har ma inganta ingancin ginin ƙarshe da rage lahani da matsaloli a cikin ginin. Sabili da haka, fahimtar da sarrafa waɗannan hanyoyin don inganta yawan ajiyar ruwa yana da matukar mahimmanci ga kamfanonin da ke samarwa da amfani da foda.
