Li ntlafatsa boreledi, ho ata ha tsona, le ts'ebetso ea ho thapolla lithōle.
Katoloso ea Nako ea ho Bula
Li liehisa ho oma ha bokaholimo, li lumella ho tenyetseha haholoanyane ha ho kenngoa.
Tshebetso e Khahlanong le ho Sag
Li eketsa ho teteana ha letlalo 'me li thibela ho thella holim'a libaka tse otlolohileng.
Lebaka Leo e Leng ea Bohlokoa
Ntle le ether ea cellulose:
- Seretse se lahleheloa ke metsi kapele haholo
- Ho ba le ho khomarela ho fokolang
- Ho petsoha hoa eketseha
Cellulose ether e nkoa e leSesebelisoa sa bohlokoa ka ho fetisisa sa ho eketsa ts'ebetso lits'ebetsong tsa seretse se ommeng.
2. Phofo ea Polymer e ka Nchafatsoang (RDP)
Phofo ea Polymer e ka qhaloang hapeke sehlomathiso se fetotsweng ke polymer se ntlafatsang ho tenyetseha le ho kgomarela.
Mefuta e tloaelehileng e kenyelletsa:

Mesebetsi e ka Sehloohong
Ntlafatso ea ho Khomarela
RDP e etsa filimi ea polymer e tenyetsehang e matlafatsang kamano pakeng tsa seretse le substrate.
Ntlafatso ea ho tenyetseha
E fokotsa ho robeha ha thepa e entsoeng ka samente.
Khanyetso ea Mapetso
E thusa ho monya khatello ea maikutlo e bakoang ke liphetoho tsa mocheso le motsamao oa sebopeho.
Khanyetso ea Metsi
E fokotsa ho kenella ha metsi 'me e ntlafatsa ho tšoarella.
Lebaka Leo e Leng ea Bohlokoa
RDP e fetola litsamaiso tsa samente e tiileng hore e beli-mortar tse tenyetsehang, tse sebetsang hantlee loketse lits'ebetso tsa sejoale-joale tse kang:
- Likhomaretsi tsa thaele
- Mekhoa ea EIFS
- Lokisa li-mortar
3. Li-Superplasticizer (PCE - Polycarboxylate Ether)
Li-superplasticizer ke li-reducer tse fokotsang metsi tse sebelisoang haholo lits'ebetsong tsa samente tsa sejoale-joale.
Mesebetsi e ka Sehloohong
Phokotso ea Metsi
Li fokotsa tlhoko ea metsi ha li ntse li boloka bokhoni ba ho sebetsa.
Ntlafatso ea Matla
Metsi a tlase a lebisa ho matla a ho hatella a phahameng.
Ntlafatso ea Phallo
Li ntlafatsa ho phalla ha metsoako le li-grout tse iketsang.
Lebaka Leo e Leng ea Bohlokoa
Li-superplasticizer li nolofalletsa:
- Seretse se matla haholo
- Mekhoa ea ho ikamahanya le maemo
- Lisebelisoa tsa konkreite e pompehang
Li bohlokoa bakeng salitsamaiso tsa samente tse sebetsang hantle, tse se nang metsi a mangata.
4. Baemeli ba Koetlisoang ke Moea
Lisebelisoa tse kenyang moea li kenya lipululana tsa moea tse laoloang ka har'a seretse.
Mesebetsi e ka Sehloohong
Ho Hatsetsa–Ho Qhibiliha
Likheo tsa moea li monya khatello ea katoloso e tsoang metsing a batang.
Ho ntlafala ha ho sebetsa
Li etsa hore ho be bonolo ho sebelisa le ho hasanya seretse.
Botebo bo Fokotsehileng
Botenya bo tlase bo ntlafatsa ho thibela mocheso.
Lebaka Leo e Leng ea Bohlokoa
Maemong a batang, lintho tse kenyang moea lia hlokahala bakeng sa:
- Samente ea kantle
- Likamore tsa ho lokisa litsela
- Kaho ea boemo ba leholimo bo batang
Li ntlafala haholoho tšoarella tlas'a maemo a thata a tikoloho.
5. Bareti le Batsamaisi ba Litlhophiso
Baretarders ba laola sekhahla sa metsi a samente.
Mefuta e tloaelehileng e kenyelletsa:
- Asiti ea citric
- Asiti ea Tartaric
- Metswako e thehiloeng ho phosphate
Mesebetsi e ka Sehloohong
Ho Beha Taolo ea Nako
Li liehisa linako tsa pele le tsa ho qetela tsa ho beha.
Katoloso ea Bokhoni ba ho Sebetsa
Li lumella nako e telele ea ho sebetsa bakeng sa libaka tse kholo tsa kaho.
Thibela ho thatafala pele ho nako
Bohlokoa bakeng sa lits'ebetso tsa boemo ba leholimo bo chesang.
Lebaka Leo e Leng ea Bohlokoa
Ntle le ho beha taolo:
- Seretse se ka thatafala kapele haholo
- Boleng ba kopo boa fokotseha
- Keketseho ea litšila
Bareti ba bohlokoa bakeng sataolo ea mocheso le ho tenyetseha ha kaho.
Litlamorao tsa ho Kopanela Litlatsetso
Mekhoa ea seretse sa sejoale-joale, lintho tse ling ha li sebetse ka boikemelo.
Ho e-na le hoo, lia sebelisana:
- Cellulose ether → ho boloka metsi + ho sebetsa habonolo
- RDP → ho tenyetseha + ho khomarela
- PCE → phallo + matla
- Li-air entertrainers → ho tšoarella
- Barekisi → taolo ea nako
Hammoho ba thehasistimi ea seretse e sebetsang hantle haholo.
Libaka tsa Kopo tsa Seretse se Fetotsoeng
Li-mortar tsa sejoale-joale tse thehiloeng ho tlatsetso li sebelisoa ho:
- Likhomaretsi tsa thaele (C1, litsamaiso tsa C2)
- Setlolo sa lebota le lijase tse sa koaheloang ka letsoho
- Metsoako e iketsang
- Mekhoa ea ho kenya mocheso ea EIFS
- Lokisa li-mortar
- Liplaster tse entsoeng ka gypsum
Tšebeliso e 'ngoe le e 'ngoe e hloka tekanyo e fapaneng ea li-additives.
Bohlokoa ba Moruo
Le hoja li-additives li emela karolo e nyane ea litšenyehelo tsohle tsa tlhahiso, li fana ka:
- Ho hloleha ha kaho ho fokotsehile
- Litšenyehelo tse tlase tsa tlhokomelo
- Bokgoni bo phahameng ba ho kenya
- Nako e ntlafetseng ea bophelo ba moaho
Ke e 'ngoe eaLikarolo tse phahameng ka ho fetisisa tsa ROI k'hemistri ea kaho.
Mekhoa ea Tikoloho
Lisebelisoa tsa sejoale-joale li ntse li eketseha:
- E thehiloeng ho bio (li-derivatives tsa cellulose)
- VOC e Tlase
- Tlhahiso e bolokang matla
Ho tšoarella ho fetoha sesosa sa bohlokoa sa boqapi bo eketsehileng.
Tshebetso ya seretse sa sejwalejwale e itshetlehile haholo hodima di-additives tsa dikhemikhale. Di-additives tse hlano tsa bohlokwa—di-cellulose ethers,RDP, li-superplasticizer, li-agent tse kenyang moea, le balaoli ba ho beha—li sebetsa 'moho ho fetola metsoako ea motheo ea samente hore e be thepa ea kaho e sebetsang hantle.
Ho utloisisa lintho tsena tse eketsang ho lumella bahlahisi le borakonteraka ho rala li-mortar tse fihlelang litlhoko tsa kaho ea sejoale-joale: tse matla, tse tenyetsehang haholoanyane, tse tšoarellang haholoanyane le tse sebetsang hantle haholoanyane.
Ha maemo a kaho a ntse a tswela pele ho fetoha, theknoloji ya tlatsetso e tla dula e le motheo wa boqapi ditsamaisong tsa seretse.
