1. Redispersible latex foda
Wannan abu mai shayar da baki wani nau'in polymer ne na musamman mai tsayi, wanda ake yin shi ya zama foda bayan bushewar feshi. Bayan tuntuɓar ruwa, wannan foda zai iya sake zama emulsion kuma yana da kaddarorin iri ɗaya kamar emulsion. Bayan ruwan ya ƙafe, zai iya samar da fim. Fim ɗin yana da babban sassauci, tsayin daka na yanayi, kuma yana nuna babban mannewa ga maɓalli daban-daban.
Saboda haka, shi ne wani makawa raw abu a bushe-mixed turmi, wanda zai iya inganta yi, ƙara ƙarfi, inganta adhesion na bushe foda turmi zuwa daban-daban substrates, inganta sassauci, matsawa ƙarfi, da kuma sa juriya bushe foda turmi. Bugu da ƙari, Idan an haɗe shi da foda na latex na hydrophobic, zai iya sa busassun busassun turmi ya hana ruwa.
2. Cellulose
Cellulose tare da viscosities daban-daban yana da amfani daban-daban. Ana iya amfani da Cellulose a cikin ƙananan ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar cuta don bango na ciki, wanda zai iya ƙarfafa riƙewar ruwa da ƙara haɓaka. Yana da tsayayye a cikin sinadarai, yana iya hana mildew, yana da tasiri mai kyau na riƙe ruwa, kuma canje-canje a ƙimar pH ba ya shafar shi. Ana iya amfani da shi daga 50,000 zuwa 200,000 viscosities. Ƙarfin haɗin gwiwa yana da bambanci, danko yana da girma, amma ƙarfin yana da ƙananan, gabaɗaya tsakanin 50,000 zuwa 100,000. Yana da yafi don ƙara matakin da constructability na busassun foda turmi, da kuma daidai da rage adadin siminti.
Bugu da ƙari, turmi siminti yana da lokacin ƙarfafawa. A lokacin ƙarfafawa, ana buƙatar kulawa da hannu don kiyaye shi da ɗanshi. Saboda riƙewar ruwa na cellulose, ana iya samun danshin da ake buƙata don ƙarfafa turmi daga riƙewar ruwa na cellulose, don haka za'a iya ƙarfafa shi ba tare da kulawa ta musamman ba.
3. Lignin
Matsayin lignin a cikin busassun busassun turmi shine don tsayayya da fashewa. Lokacin da aka tarwatsa lignin a cikin ruwa, yana wanzuwa a cikin nau'i na gajerun fibers. Misali, lokacin gina katanga tare da ƙasa a cikin gida, ana ƙara bambaro na alkama da bambaro shinkafa don hana tsagewa. Lokacin amfani da lignin, yana da kyau a zaɓi kayan tsabta ba tare da ƙazanta ba. Lokacin gano lignin, zaku iya juya lignin don ganin ko akwai wata ƙura da ta rage. Ƙarin foda, mafi muni da inganci. Ko kuma a zuba lignin kadan a cikin ruwa sannan a duba, idan aka watsar da shi, zai fi kyau, ma’ana idan aka hada shi da busasshiyar turmi, yana da sauki a watse kuma ba za ta yi kwallo ba.
4. Inorganic bonding abu
Ash calcium foda shine calcium hydroxide, kayan haɗin da aka saba amfani dashi. Yafi taka rawa a bonding a putty foda don cimma ruwa mai hana ruwa da kuma ruwa-resistant effects. Akwai wurare da yawa da ake samar da farar ƙasa a kasar Sin, don haka samar da sinadarin calcium foda ya zama ruwan dare gama gari. Duk da haka, a wasu wurare, turmi da aka yi da foda na calcium na lemun tsami da aka samar zai iya ƙone fatar hannu yayin gini. Exothermic dauki, don haka daftarin ash calcium foda ne sosai alkaline. Girman daftarin, mafi yawan rashin kwanciyar hankali, kuma yana da sauƙi a fashe lokacin da aka zazzage shi a bango. Muna neman wani abu mai ingantacciyar ash ash foda, wanda ke da ɗan ƙaramin daftari, fari mai kyau, kuma baya ɓarna hannu.
