Seretse ke thepa ea bohlokoa ea ho haha e sebelisoang mererong e meholo le e menyenyane ea kaho. Hangata e na le samente, lehlabathe le metsi hammoho le lisebelisoa tse ling. Leha ho le joalo, ka tsoelo-pele ea theknoloji, li-additives tse ngata li hlahisitsoe ho ntlafatsa matla a ho kopanya, ho feto-fetoha ha maemo le ho hanyetsa metsi a seretse.
E 'ngoe ea likenyelletso tsa morao-rao lefatšeng la li-additives tsa seretse ke tšebeliso ea li-polymer tse tlamang. Li-polymers tsa binder ke lisebelisoa tsa maiketsetso tse matlafatsang matla a maqhama a seretse. Li kenngoa seretseng nakong ea ho kopanya 'me li itšoara ka samente ho theha maqhama a matla. Tšebeliso ea li-polymers tse tlamang li bontšitsoe ho ntlafatsa thepa ea mechine ea liretse, e leng ho etsa hore e be khahlanong le ho phunyeha le ho kenella ha metsi.
Keketso e 'ngoe e seng e tumme lilemong tsa morao tjena ke redispersible polymer powder (RDP). RDP ke polymer e sebelisoang ho ntlafatsa thepa ea seretse. E entsoe ka motsoako oa li-resin tsa polymer tse ntan'o kopanngoa le phofo ea samente, metsi le lisebelisoa tse ling. RDP e ntse e tsebahala haholo ka lebaka la ho feto-fetoha ha eona le thepa e ikhethang.
E 'ngoe ea melemo e ka sehloohong ea ho sebelisa RDP ka seretse ke bokhoni ba eona ba ho eketsa ho tenyetseha ha sehlahisoa se felileng. Tšobotsi ena ke ea bohlokoa ka ho khetheha libakeng tseo mehaho e atisang ho ba le litšisinyeho tsa lefatše le likoluoa tse ling tsa tlhaho. Liretse tse entsoeng ka RDP li pakiloe li tšoarella haholoanyane, li tenyetseha ebile ha li na monyetla oa ho petsoha tlas'a khatello. Ho feta moo, RDP e ka matlafatsa khanello ea metsi, ea e etsa tlatsetso e molemo libakeng tse nang le pula e ngata.
Ntle le ho ntlafatsa ho feto-fetoha ha maemo le ho hanyetsa metsi, RDP e boetse e ntlafatsa ho sebetsa ha seretse. E etsa bonnete ba hore seretse se ata le ho beha ka ho lekana, ho nolofaletsa lihahi. Sena se bohlokoa haholo ha ho hahoa mabota, fuluru le libaka tse ling tse hlokang hore ho be le qetello e tsitsitseng. RDP e boetse e fokotsa bongata ba metsi a hlokahalang nakong ea ho kopanya, e leng se etsang hore ho be le seretse se momahaneng se nang le likheo tse fokolang.
Tšebeliso ea li-additives tsa seretse tse kang li-polymers tse tlamang le li-polymer powders tse ka sebelisoang hape li fetola indasteri ea kaho. Li-mortar tse nang le li-additives tsena li matla, li fetoha habonolo ebile li hanana le metsi, li tiisa hore mohaho o tšoarella le o tšoarellang nako e telele. Hoa lokela ho hlokomeloa hore li-additives tsena li tlameha ho sebelisoa ka tekanyo e nepahetseng. Likarolo tse khothaletsoang ke moetsi li tlameha ho lateloa ho qoba ho ama boleng ba seretse.
Indasteri ea kaho e lula e fetoha 'me lintlafatso tse fapaneng tsa thepa ea kaho lia thabisa. Tšebeliso ea li-additives liretseng, tse kang li-polymers tse tlamang le li-polymer powders tse redispersible, ke mohato o lebisang tseleng e nepahetseng ho netefatsa hore mohaho o tšoarella le o tsitsitseng. Li-additives tsena li tiisa hore mohaho o ka mamella likoluoa tsa tlhaho, likhohola le lintlha tse ling tse ka senyang botšepehi ba oona. Ka hona, tsoelopele ena e tlameha ho amoheloa le ho sebelisoa ho aha meaho e betere le e matla nakong e tlang.
