Iyo yakajairika yakaoma dhaka additives nemhedzisiro yavo

Dry mortar additives inotamba mabasa akakosha mukuvandudza mashandiro, kushanda, uye kusimba kwekuumbwa kwedhaka. Heano mamwe akajairika dry mortar additives nemhedzisiro yawo:

1. Cellulose Ethers:

• Mhedzisiro: Cellulose ethers, seHydroxypropyl Methylcellulose (HPMC) neHydroxyethyl Cellulose (HEC), inoshanda semakobvu, ekuchengetedza mvura, uye rheology modifiers mune yakaoma dhaka maumbirwo.
• Benefits: Vanovandudza kushanda, kunamatira, uye sag kuramba, kuderedza shrinkage uye kutsemuka, kuwedzera kuchengetwa kwemvura, uye kupa zvirinani kuvhura nguva uye nyore kushandisa.

2. Redispersible Polymer Powders (RDPs):

• Mhedzisiro: RDPs ma copolymers evinyl acetate uye ethylene anopararira mumvura uye emulsify pakuomeswa, kuvandudza kunamatira, kushanduka, uye kusimba kwematope.
• Benefits: Vanosimudzira kusimba kwechisungo, kubatana, uye kuramba mvura, kuderedza kutsemuka uye shrinkage, kunatsiridza kusamira kwemamiriro ekunze, uye kuwedzera kuchinjika kwemajoini edhaka.

3. Air-Entraining Agents:

• Mhedzisiro: Air-entraining agents anopinza tutubu twemhepo mumisanganiswa yedhaka, inovandudza kutonhora-kunyungudika, kushanda, uye plastiki.
• Benefits: Vanonatsiridza kusimba, kuderedza njodzi yekutsemuka uye kuparara kunokonzerwa nechando-nyoro kutenderera, uye kunatsiridza kushanda uye kupomba kwedhaka musanganiswa.

4. Retading Agents:

• Mhedzisiro: Vamiririri vanodzosa vanononoka kudzika nguva yekumisikidza yedhaka, zvichibvumira nguva yakareba yakavhurika uye kushanda.
• Benefits: Vanovandudza kushanda, vanowedzera nguva yekunyorera, uye vanodzivirira nguva isati yakwana, kunyanya mukupisa kana kushanda nenzvimbo huru.

5. Kuwedzera maAgents:

• Mhedzisiro: Vanomhanyisa vamiririri vanomhanyisa kuseta uye nekutanga simba kusimudzira kwedhaka, zvichibvumira kukurumidza kufambira mberi kwekuvaka.
• Benefits: Vanoderedza nguva yekurapa, kukurumidza kuwedzera simba, uye kubvumira kupedzwa kwekutanga kana kurodha zvinhu zvezvimiro, kuwedzera chibereko uye nguva yeprojekiti.

6. Zvinoderedza Mvura (Plasticizers):

• Mhedzisiro: Zvinoderedza mvura zvinovandudza kuyerera uye kushanda kwemusanganiswa wedhaka nekudzikisa reshiyo yemvura-kune-simende.
• Benefits: Vanowedzera kushanda, kuwedzera kupomba, kuderedza kupatsanurwa uye kubuda ropa, kunatsiridza kukura kwesimba, uye kubvumira kugadzirwa kwepamusoro-soro, mvura yakaderera-yakawanda.

7. Anti-Washout Agents:

• Mhedzisiro: Anti-washout agents anovandudza kubatanidzwa uye kunamatira kwedhaka pasi pemvura kana mumamiriro ekunyorova, kudzivirira kushambidzwa kwemasimende esimende.
• Benefits: Vanosimudzira kusimba uye chisungo chesimba repasi pemvura kana dhaka rakanyorova, kuderedza njodzi yekutadza uye kuve nechokwadi chekushanda kwenguva refu munzvimbo dzemugungwa kana pasi pemvura.

8. Anti-Kupwanya Agents:

• Mhedzisiro: Anti-cracking agents anoderedza njodzi yekutsemuka mudhaka nekudzora shrinkage uye kukurudzira kuzorora kwemukati kushushikana.
• Benefits: Vanovandudza kusimba, chitarisiko, uye chimiro chekuvimbika kwedhaka, kuderedza kuitika kwekutsemuka kwekuputika uye kuwedzera kushanda kwenguva refu.

Muchidimbu, zvakajairika dhaka rakaoma rinowedzera senge cellulose ethers, redispersible polymer powders, air-entraining agents, retarding agents, accelerating agents, water reducers, anti-washout agents, uye anti-cracking agents vanoita basa rakakosha mukuvandudza kushanda, kushanda, kusimba, uye kutaridzika kwedhaka maumbirwo, kugovera kune chaiyo application zvinodiwa uye mamiriro ezvakatipoteredza.
