E boetse e ntlafatsa ho tenyetseha, ho sebetsa le ho tšoarella ha sekhomaretsi sa lithaele.Ha e kopane le metsi, phofo ea polymer e qhalakantsoeng e etsa filimi holim'a lithaele le li-substrates.Filimi e fana ka maqhama a matla 'me e thibela metsi hore a se ke a phalla pakeng tsa lithaele, ho fokotsa kotsi ea ho phunyeha kapa ho arohana.Ka kakaretso, redispersible polymer powder ke karolo ea bohlokoa mefuteng ea sekhomaretsi sa lithaele kaha e ntlafatsa ts'ebetso le ho tšoarella ha sekhomaretsi, ho netefatsa hore ho kenngoa lithaele tse tšoarellang nako e telele le tse tšepahalang.
Phofo ea latex e ka qhaloang hapes e ka boela ea sebelisoa e le li-additives tse entsoeng ka konkreite ho ntlafatsa thepa e sa tšoaneng le litšobotsi tsa ts'ebetso ea konkreite.Mona ke tse ling tsa ts'ebeliso e tloaelehileng ea li-polymer powders tse ka sebelisoang hape ka konkreite:
Ntlafatso ea ts'ebetso leho khomarela lithaele:
Li-powders li thusa ho ntlafatsa ts'ebetso ea konkreite, ho etsa hore ho be bonolo ho kopanya, ho pompa le ho beha sebaka.E boetse e ntlafatsa ho khomarela pakeng tsa konkreite le libaka tse ling, tse kang ho roala kapa ho koahela.
E Ntlafetseng ea ho Fetolana le ho hanyetsa Crack:
Redispersible polymer phofo e eketsa ho tenyetseha ha konkreite, e etsa hore e se ke ea thijoa habonolo.Sena se bohlokoa ka ho khetheha lits'ebetsong tsa konkreite moo ho hlokahalang matla a holimo kapa a ho feto-fetoha, joalo ka likarolo tsa meralo kapa likoahelo tse tšesaane.
Matla a Matlafalitsoeng le a Hanyetsa Metsi:
Phofo ea polymer e etsa filimi e sireletsang ho pota-potile likaroloana tsa samente ka konkreite, e leng ho etsang hore e be e hanyetsanang le ho kenella ha metsi.Sena se thusa ho thibela mathata a kang boemo ba leholimo, tšenyo ea leqhoa, le ho senyeha ho bakoang ke ho pepesehela maemo a thata a tikoloho.
Matla le Matla a Ntlafetseng:
Li-polymer powders tse ka sebelisoang hapee ka matlafatsa matla a hatellang, matla a feto-fetohang le ho hanyetsa ha konkreite, ho etsa hore e tšoarelle le ho lokela lits'ebetso tse hlokang.
Fokotsa ho Shrinkage le ho Ntlafatsa Taolo ea Crack:
Keketso ena e thusa ho fokotsa shrinkage le ho fokotsa kotsi ea ho phatloha nakong ea ts'ebetso ea konkreite.Sena se thusa ho qoba mapetsong a sa hlokahaleng a ho theha, a ka senyang botšepehi ba sebopeho sa konkreite.Ka kakaretso, ho eketsoa ha li-polymer powders tse ka sebelisoang hape ho lihlahisoa tsa konkreite ho ka ntlafatsa haholo ts'ebetso, ho tšoarella, ho hanyetsa metsi le ts'ebetso e akaretsang ea konkreite, ho etsa hore e tšoanelehe bakeng sa mekhoa e mengata ea kaho.
