Ke mokhoa ofe oa ts'ebetso ea phofo ea polymer e ka sebelisoang hape?

Mokhoa oa ts'ebetso oa li-polymer powders tse ka sebelisoang hape (RPP) o kenyelletsa ho sebelisana ha bona le metsi le likarolo tse ling tsa metsoako ea seretse, e lebisang ho ntlafatseng tshebetso le thepa. Mona ke tlhaloso e qaqileng ea mokhoa oa ts'ebetso oa RPP:

1. Ho hasana hape ka Metsing:
   • RPP e etselitsoe ho hasana habonolo ka metsing, ho etsa li-suspensions tse tsitsitseng tsa colloidal kapa tharollo. Redispersibility ena e bohlokoa bakeng sa ho kenyelletsoa ha tsona ka har'a metsoako ea seretse le hydration e latelang.
2. Tlhahiso ea lifilimi:
   • Ha e hasana hape, RPP e theha filimi e tšesaane kapa e koahelang likaroloana tsa samente le likarolo tse ling tsa matrix a seretse. Filimi ena e sebetsa e le tlamahano, e tlamella likaroloana hammoho le ho ntlafatsa momahano ka har'a seretse.
3. Ho khomarela:
   • Filimi ea RPP e ntlafatsa ho khomarela pakeng tsa likarolo tsa seretse (mohlala, samente, li-aggregates) le libaka tsa substrate (mohlala, konkreite, masonry). Khomarelo ena e ntlafalitsoeng e thibela delamination mme e tiisa maqhama a matla lipakeng tsa seretse le substrate.
4. Paballo ea Metsi:
   • RPP e na le thepa ea hydrophilic e ba nolofalletsang ho monya le ho boloka metsi ka har'a matrix a seretse. Ts'ebetso ena e ntseng e eketseha ea ho boloka metsi e lelefatsa hydration ea lisebelisoa tsa cementitious, e leng se bakang ts'ebetso e ntlafetseng, nako e telele e bulehileng, le ho ntlafatsa ho khomarela.
5. Ho fetoha ha maemo le ho ba bonolo:
   • RPP e fana ka bonolo le elasticity ho matrix ea seretse, e etsa hore e se ke ea hlola e qhekella le ho senyeha. Ho feto-fetoha ha maemo hona ho lumella seretse ho amohela motsamao oa substrate le katoloso ea mocheso / ho honyela ntle le ho sekisetsa botšepehi ba ona.
6. Tšebeliso e ntlafetseng:
   • Ho ba teng ha RPP ho ntlafatsa ho sebetsa le ho tsitsa ha seretse, ho etsa hore ho be bonolo ho kopanya, ho sebelisa le ho hasana. Ts'ebetso ena e ntlafalitsoeng e fana ka tšireletso e ntle le ts'ebeliso e ts'oanang, e fokotsang menyetla ea likheo kapa likheo seretseng se felileng.
7. Ntlafatso ea ho tšoarella:
   • Liretse tse fetotsoeng tsa RPP li bonts'a ho tšoarella ho ntlafetseng ka lebaka la ho hanyetsa ha tsona boemo ba leholimo, tlhaselo ea lik'hemik'hale le ho senyeha. Filimi ea RPP e sebetsa e le thibelo e sireletsang, e sireletsa seretse ho bahlaseli ba ka ntle le ho lelefatsa bophelo ba eona ba tšebeletso.
8. Phatlalatso e Laolang ea Li-additives:
   • RPP e ka kenyelletsa le ho lokolla metsoako e sebetsang kapa li-additives (mohlala, li-plasticizers, accelerators) ka har'a matrix a seretse. Mokhoa ona o laoloang oa tokollo o lumella ts'ebetso e lokiselitsoeng le libopeho tse ikhethileng ho fihlela litlhoko tse ikhethileng tsa kopo.

mokhoa oa ts'ebetso oa phofshoana ea polymer e qhalakantsoeng e kenyelletsa ho hasana ha tsona hape ka metsing, sebopeho sa filimi, ho ntlafatsa ho khomarela, ho boloka metsi, ntlafatso ea ho feto-fetoha ha maemo, ntlafatso ea ts'ebetso, ntlafatso ea nako e telele, le tokollo e laoloang ea li-additives. Mekhoa ena ka kopanelo e kenya letsoho ntlafatsong ea ts'ebetso le thepa ea lirekere tse fetotsoeng tsa RPP lits'ebetsong tse fapaneng tsa kaho.
