Ndeipi basa remhepo inopinza agent mortar?

Nhanganyaya:

Doka musanganiswa wesimende, jecha, nemvura unoshandiswa pakuvaka kusunga zvidhinha kana kuti zvidhinha. Icho chinhu chakakosha chekuvaka masonry uye chinoshandiswa mumhando dzakasiyana siyana, kusanganisira kukanya zvidhinha, kuvharira, kugadzira matombo, uye kupurasita. Air etraining agents (AEA) imhando yemakemikari ekuwedzera anogona kushandiswa mudhaka kuvandudza zvimiro zvayo. Muchikamu chino, tichakurukura basa remhepo-entraining agents mumatope uye kuti vanogona sei kuvandudza kushanda kwedhaka.

Chii chinonzi Air-Entraining Agent (AEA)?

Air-entraining agents (AEA) makemikari ekuwedzera anowedzerwa mudhaka kuti abudise madiki, akagovaniswa mabhuru emhepo mukati memusanganiswa. Aya mabhuru emhepo anogona kuvandudza kushanda, kutonhora-kunyungudika kuramba, uye kusimba kwedhaka. Air-entraining agents anowanzo organic compounds ane surfactants kana mamwe makemikari anogona kugadzira homwe dzemhepo mukati memusanganiswa. Kuwanda kwemhepo kunowanikwa mumusanganiswa kunogona kudzorwa nekugadzirisa huwandu hwemhepo-inopinza mumiririri inowedzerwa kune dhaka.

Mhando dzeAir-Entraining Agents:

Kune akati wandei marudzi emhepo-entraining agents anoshandiswa mudhaka. Mhando dzinonyanyozivikanwa dzinosanganisira:

1. Synthetic Surfactants: Aya makemikari ekugadzira akagadzirirwa kugadzira madiki, akaenzana akagovaniswa mabhuru emhepo mukati memusanganiswa. Ivo vanowanzo wedzerwa kune musanganiswa mune yemvura fomu uye inogona kushandiswa mune ese simentitious uye isiri-cementitious madhaka.
2. Natural Surfactants: Izvi zvinhu zvechisikigo, senge zvidyarwa kana mafuta emhuka, ane masurfactants. Inogona kushandiswa mune zvese cementitious uye kwete-cementitious madhaka.
3. Hydrophobic Agents: Aya makemikari anodzinga mvura uye anogona kushandiswa kugadzira homwe dzemhepo mukati memusanganiswa. Ivo vanowanzo wedzerwa kune musanganiswa mune fomu yehupfu uye inogona kushandiswa mune ese simende uye isiri-cementitious madhaka.
4. Air-Entraining Admixtures: Aya ndiwo musanganiswa wemakemikari akagadzirwa zvakananga kugadzira mabhuru madiki, akaenzana akagovaniswa mukati memusanganiswa. Ivo vanowanzo wedzerwa kune musanganiswa mune yemvura fomu uye inogona kushandiswa mune ese simentitious uye isiri-cementitious madhaka.

Basa reMhepo-Entraining Agents muMortar:

1. Kushanda:

Kuwedzerwa kwemhepo-entraining agents kudhaka kunogona kuvandudza kushanda kwayo. Iwo madiki, akaenzana akagovaniswa mabhuru emhepo mumusanganiswa anogona kuderedza kushushikana kwepamusoro kwemusanganiswa uye kuita kuti zvive nyore kuparadzira nekushandisa. Izvi zvinogona kunyanya kubatsira kana uchishanda nedhaka munzvimbo inotonhora kana yakanyorova, sezvo mabhubhu emhepo anogona kubatsira kudzivirira musanganiswa kubva pakunyanya kuoma kana kunetsa kushanda nawo.

2. Kupokana neFreeze-Thaw:

Imwe yemabhenefiti ekutanga ekushandisa mhepo-inopinza maajenti mudhaka ndeyekuti ivo vanogona kuvandudza kwayo kutonhora-kunyungudika kuramba. Mvura painotonhora, inowedzera, izvo zvinogona kukonzera kukanganisa kudhaka. Zvisineyi, mabhuru madiki, akagovaniswa zvakaenzana akagadzirwa nemhepo-etraining agents anogona kupa nzvimbo yekuti mvura iwedzere kupinda, ichideredza kuwanda kwekukuvara kunoitika. Izvi zvinogona kunyanya kubatsira mumatunhu ane nguva yechando yakaoma, uko kutonhora-kunyorova kutenderera kwakajairika.

3. Durability:

Air-entraining agents anogonawo kuvandudza kusimba kwedhaka. Iwo madiki mahomwe emhepo mukati memusanganiswa anogona kuita sebuffer pakati pezvimedu zvakasimba zvemusanganiswa, zvichideredza kushushikana kwakaiswa pavari. Izvi zvinogona kubatsira kudzivirira kutsemuka uye mamwe marudzi ekukuvadza nekufamba kwenguva, kunyanya mumamiriro ezvinhu apo dhaka rinoratidzwa nekunetseka kwakanyanya kana kudedera.

4. Kuchengeta Mvura:

Air-entraining agents anogonawo kubatsira kuvandudza kuchengetwa kwemvura kwedhaka. Zvimedu zviduku zvemhepo mukati memusanganiswa zvinogona kubatsira kudzivirira mvura kuti irege kubuda nokukurumidza kubva pamusoro pevhu, iyo inogona kunyanya kukosha mumamiriro ekupisa kana akaoma. Izvi zvinogona kubatsira kuve nechokwadi chekuti dhaka rinoramba richishanda kwenguva yakareba, zvichideredza kudiwa kwekusanganisazve kana kunyorera zvakare.

5. Bond Simba:

Imwe bhenefiti yekushandisa mhepo-inopinza maajenti mudhaka ndeyekuti ivo vanogona kuvandudza chisungo chesimba pakati pedhaka uye masonry units. Madiki emhepo mapeji mukati memusanganiswa anogona kubatsira kugadzira imwe nzvimbo ine porous, zvichibvumira dhaka kuti ribatanidze zviri nani pamusoro peiyo masonry unit. Izvi zvinogona kubatsira kugadzira chisungo chakasimba, chakasimba icho chisinganyanye kutsemuka kana kukundikana nekufamba kwenguva.

6. Yakaderedzwa Shrinkage:

Air-entraining agents anogonawo kubatsira kuderedza kuderera kwedhaka painorapa. Kana dhaka raoma, rinogona kupera zvishoma, izvo zvinogona kukonzera kutsemuka kana mamwe maitiro ekukuvadza. Nekudaro, mahomwe madiki emhepo akagadzirwa nemhepo-entraining agents anogona kubatsira kudzikisira shrinkage iyi, kuderedza njodzi yekukuvadza uye kuve nechokwadi chekuti dhaka rinoramba rakasimba uye rakagadzikana nekufamba kwenguva.

Mhedziso:

Mukupfupisa, mhepo-inopinza vamiririri vanoita basa rinokosha mukuita kwedhaka. Vanogona kuvandudza kushanda, kutonhora-kunyungudika kuramba, kusimba, kuchengetedza mvura, simba rebhondi, uye kuderedza kuderera kwedhaka, zvichiita kuti ive chinhu chakavimbika uye chinoshanda chekushandisa mukuvaka. Kune akati wandei marudzi emhepo-entraining agents anowanikwa, imwe neimwe iine yayo yakasarudzika midziyo uye mabhenefiti. Nekunzwisisa basa revanopinza mweya mudhaka, nyanzvi dzekuvaka dzinogona kusarudza mhando yakakodzera uye huwandu hwemumiririri kuti vawane mhedzisiro inodiwa uye kuona kuti mapurojekiti avo anovakwa kuti agare.
