Tlhahlobo e Felletseng ea Indasteri ea Tshebetso, Mekhoa le Mekhoa ea 'Maraka
Indastering ea kaho ea kajeno, phetoho e eang holitsamaiso tsa seretse se kopantsoeng ka ommenge fetotse tsela eo thepa ea kaho e hlahisoang, e tsamaisoang le ho sebelisoa ka eona. Har'a lintho tsa bohlokoa tse tlatsetsang tse thusang phetoho ena kePhofo ea Polymer e ka Nchafatsoang (RDP)—karolo ea bohlokoa e ntlafatsang haholo ts'ebetso ea thepa e thehiloeng samente.
Baetapele ba lik'hemik'hale lefatšeng ka bophara ba kang Wacker Chemie AG, Dow Chemical Company, le BASF SE ba bapetse karolo ea bohlokoa ho nts'etsapele mahlale a tsoetseng pele a RDP. Sengoloa sena se fana ka tlhahlobo e qaqileng, ea mokhoa oa litaba oaseo RDP e se etsang ka seretse se ommeng, ho kenyeletsoa le mekhoa ea eona, lits'ebetso, melemo le mekhoa ea nakong e tlang.
1. Ho Utloisisa Phofo ea Polymer e Nchafalitsoeng (RDP)
Phofo ea polymer e ka qhalwang hape ke phofo e phallang ka bolokolohi, e omisitsoeng ka spray e fumanoang ho tsoa ho li-emulsion tsa polymer tse kang vinyl acetate-ethylene (VAE), vinyl acetate-vinyl versatate (VA/VeoVa), kapa litsamaiso tse thehiloeng ho acrylic. Ha e kopantsoe le metsi, RDP e ajoa hape ho ba polasi e tsitsitseng ea polymer, e tšoanang le sebopeho sa eona sa pele sa emulsion.
Thepa ena e ikhethang e dumella RDP ho kopanya melemo ea li-polymer tse metsi le boiketlo ba litsamaiso tsa phofo e omileng. E sebelisoa haholo ka har'a li-mortar tse kopantsoeng ka mokhoa o omileng, ho kenyeletsoa:
- Likhomaretsi tsa thaele
- Mekhoa ea ho qeta ho kenya thepa ka ntle (EIFS)
- Metsoako e iketsang
- Lokisa li-mortar
- Li-mortar tse sa keneleng metsi
2. Ho Theha Filimi: Mokhoa oa Bohlokoa oa RDP
Mosebetsi oa bohlokoa ka ho fetisisa oaRDP is ho thehoa ha filimiKamora ho kopanya le metsi le ho sebelisa seretse, metsi a fetoha mouoane butle-butle, a lumella likaroloana tsa polymer ho kopana ho ba filimi e tsoelang pele ka har'a matrix ea samente.
Filimi ena ea polymer:
- Ho kopanya likheo pakeng tsa likaroloana tsa samente
- E ntlafatsa kutloano le ho tenyetseha
- E ntlafatsa ho khomarela li-substrate
Sephetho ke thepa e kopaneng e kopanyang matla a samente le ho tenyetseha ha li-polymer, e ntlafatsang haholo ts'ebetso ka kakaretso.
3. Ho Ntlafatsa Matla a Khomarelo le a Bond
E 'ngoe ea mesebetsi ea mantlha ea RDP ke ho ntlafatsaho khomarela. Likhomaretsing tsa thaele le li-mortar tsa tokiso, ho khomarelana ho matla le lintho tse kang konkreite, litene, kapa lithaele hoa hlokahala.
RDP e ntlafatsa ho khomarela ka:
- Ho eketsa sebaka sa ho kopana pakeng tsa seretse le substrate
- Ho etsa filimi ea polymer e tenyetsehang e kenang ka har'a masoba a holim'a metsi
- Ho fokotsa khatello ea maikutlo ea ho fokotseha
Sena se lebisa ho:
- Matla a tlamo e matla a ho tsitlella
- Kotsi e fokotsehileng ea ho tsoa ha bond
- Ho ntlafala ha nako e telele
4. Ho Ntlafatsa ho Tenyetseha le ho Hanela Mapetso
Dikatara tsa setso tse thehilweng ka samente di a robeha habonolo mme di ka petsoha ha di le tlasa kgatello. RDP e sebetsana le bothata bona ka ho kenya tenyetseho tsamaisong.
Melemo e kenyelletsa:
- Ho eketseha ha elasticity
- Ho hanyetsa hamolemo katoloso ea mocheso le ho fokotseha ha mocheso
- Ho fokotseha ha ho thehoa ha mapetso
Sena se bohlokoa haholo lits'ebetsong tse pepesehetseng:
- Ho feto-fetoha ha mocheso
- Khatello ea mechine
- Motsamao oa substrate
5. Tshebetso ea ho Hanela Metsi le ho Thibela Metsi
RDP e bapala karolo ea bohlokoa ntlafatsongho hanyetsa metsiFilimi ea polymer e entsoeng ka har'a seretse e fokotsa ho monngoa ha metsi ka har'a capillary 'me e eketsa ho se kenelle.
Litlamorao tsa bohlokoa:
- Ho fokotseha ha ho kenella ha metsi
- Ho hanyetsa pula le mongobo ho ntlafetse
- Ho tšoarella ho matlafalitsoeng libakeng tse mongobo
Ha e kopantsoe le lintho tse eketsang metsi, RDP e kenya letsoho lits'ebetsong tsa ho thibela metsi tse sebetsang hantle.
6. Bokgoni ba ho Sebetsa le Tshebetso ya Tshebediso
RDP e ntlafatsa bokgoni ba ho sebetsa ba di-dry-mix mortar, e leng se etsang hore ho be bonolo ho di kopanya, ho di sebedisa le ho di qeta.
E kenya letsoho ho:
- Ho tsitsa ho boreleli
- Ho ata ho betere
- Ho khomarela ho fokotsehile nakong ea kopo
Sena se ntlafatsa bokgoni ba kaho mme se fokotsa boiteko ba basebetsi.
7. Khanyetso ea Tšusumetso le Matla a Mekaniki
RDP e ntlafatsa thepa ea mechini ea seretse, haholo-holo:
- Matla a ho tenyetseha
- Khanyetso ea tšusumetso
- Khanyetso ea ho khohlela
Sebopeho se fetotsweng ke polymer se monya matla ka katleho ho feta ditsamaiso tsa samente tsa setso, e leng se etsang hore se lokele ditshebediso tse nang le kgatello e phahameng.
8. Ho lumellana leLi-Ether tsa Cellulose
Hangata RDP e sebediswa mmoho le di-ether tsa cellulose tse kang HPMC le MHEC. Di-additives tsena di a tlatsana:
- Ether ea selulose: E fana ka ho boloka metsi le ho sebetsa habonolo
- RDP: E ntlafatsa ho khomarela le ho tenyetseha
Tšebelisano ena e fella ka ts'ebetso e ntlafalitsoeng ea seretse.
9. Litšebeliso ho Mekhoa ea Kaho ea Sejoale-joale
RDP e sebelisoa haholo lits'ebetsong tse fapaneng:
Likhomaretsi tsa Lithaele
E ntlafatsa matla a ho kopanya le ho tenyetseha ha lithaele tse kholo.
Mekhoa ea EIFS
E ntlafatsa ho tšoarella ha sistimi ea ho thibela ho ruruha le ho hanyetsa mapetso.
Metsoako e Itekanetseng
E ntlafatsa phallo le qetello ea bokaholimo.
Li-mortar tsa ho lokisa
E fana ka ho khomarela ho matla le ho tšoarella.
Li-mortar tse sa keneleng metsi
E eketsa ho se kenele metsi le ho hanyetsa mongobo.
10. Melemo ea Tikoloho le Botsitso
RDP e tšehetsa kaho e tsitsitseng ka:
- Ho nolofalletsa litsamaiso tsa motsoako o omileng (ho fokotsa litšila)
- Ho ntlafatsa ho tšoarella (bophelo bo bolelele ba tšebeletso)
- Ho fokotsa litlhoko tsa tlhokomelo
Bahlahisi ba kang Wacker Chemie AG ba tsetela mahlaleng a polymer a sireletsang tikoloho.
11. Mekhoa ea 'Maraka le Nts'etsopele ea Indasteri
Mmaraka oa lefats'e oa RDP o hola ka potlako ka lebaka la:
- Tlhoko e ntseng e eketseha ea lithako tsa metsoako e ommeng
- Ntlafatso ea litoropo le meralo ea motheo
- Maemo a boleng a ntseng a hola kahong
Asia-Pacific ke sebaka se holang ka potlako, ha Yuropa e etella pele ka theknoloji e tsoetseng pele.
12. Mekhoa e Mecha ea Bocha ea Nakong e Tlang
Lintlafatso tsa nakong e tlang tsa RDP li kenyelletsa:
- Mekhoa e tlase ea VOC le e mosa tikolohong
- Ho ntlafala ha ho qhalana hape
- Ts'ebetso e ntlafalitsoeng ka litekanyetso tse tlase
- Lisebelisoa tse bohlale tse nang le thepa ea ho ipholisa
