Tsarin Samar da Fim na RDP a Turmi Siminti

Tsarin samar da fim ɗin Redispersible Polymer Powder (RDP) a cikin turmi siminti ya ƙunshi matakai da yawa waɗanda ke ba da gudummawa ga haɓaka fim ɗin polymer mai haɗin kai da ɗorewa.Ga bayyani kan tsarin samar da fim:

1. Watsawa: Da farko, ana tarwatsa barbashi na RDP daidai gwargwado a cikin lokaci mai ruwa da tsaki na cakuda turmi siminti.Wannan tarwatsawa yana faruwa a lokacin haɗuwa, inda aka shigar da barbashi na RDP a cikin cakuda turmi tare da wasu busassun sinadaran.
2. Ruwa: Bayan haɗuwa da ruwa, ƙwayoyin polymer na hydrophobic a cikin RDP sun fara kumbura da shayar da danshi.Wannan tsari, wanda aka sani da hydration, yana haifar da barbashi na polymer don yin laushi kuma ya zama mai sauƙi.
3. Samar da Fim: Yayin da ake amfani da cakudawar turmi kuma ya fara warkewa, barbashi na RDP masu ruwa da ruwa suna haɗuwa kuma suna haɗawa tare don samar da fim ɗin polymer mai ci gaba.Wannan fim ɗin yana manne da saman matrix na turmi kuma yana ɗaure ɓangarorin mutum tare.
4. Haɗin kai: Yayin aikin warkewa, ɓangarori na RDP na kusa suna shiga cikin hulɗa kuma suna jurewa, inda suke haɗuwa kuma suna samar da haɗin gwiwar intermolecular.Wannan tsarin haɗin gwiwar yana ba da gudummawa ga samar da haɗin kai da ci gaba da hanyar sadarwa ta polymer a cikin matrix turmi.
5. Crosslinking: Yayin da turmi siminti ke warkewa kuma yana taurare, haɗin gwiwar sinadarai na iya faruwa tsakanin sarƙoƙin polymer a cikin fim ɗin RDP.Wannan tsarin haɗin gwiwar yana ƙara ƙarfafa fim ɗin kuma yana haɓaka mannewa da mannewa da sauran abubuwan turmi.
6. Bushewa da Ƙarfafawa: Tumin siminti yana shan bushewa da ƙarfafawa yayin da ruwa ke ƙafewa daga cakuɗen da siminti ɗin daurin.Wannan tsari yana taimakawa wajen ƙarfafa fim ɗin RDP kuma ya haɗa shi cikin matrix turmi mai tauri.
7. Samar da Fina-Finan Karshe: Bayan kammala aikin warkewa, fim ɗin RDP ya haɓaka gabaɗaya kuma ya zama wani ɓangare na tsarin siminti na siminti.Fim ɗin yana ba da ƙarin haɗin kai, sassauci, da dorewa ga turmi, haɓaka aikin gabaɗaya da juriya ga fashewa, nakasawa, da sauran matsalolin injina.

tsarin samar da fina-finai na RDP a cikin turmi siminti ya haɗa da hydration, coalescence, crosslinking, da matakan ƙarfafawa, waɗanda ke ba da gudummawa ga ci gaban fim ɗin polymer mai haɗin gwiwa da ɗorewa a cikin matrix turmi.Wannan fim yana haɓaka mannewa, sassauƙa, da dorewa na turmi, yana haɓaka aikin sa a cikin aikace-aikacen gini daban-daban.
