Iyo anionic surfactant iri mukatikuvakazvinowedzera zvinogona kuita kuti masemende zvimedu zvipararire mumwe nemumwe kuitira kuti mvura yemahara yakavharidzirwa nesamende aggregate isunungurwe, uye iyo agglomerated simenti aggregate yakapararira uye yakanyatso hydrated kuti iwane dense chimiro uye kuwedzera simba revhu, kunatsiridza kusamira, kutsemuka kuramba uye. durability.
Iyo dhaka yakasanganiswa nezvinowedzerwa ine kushanda kwakanaka, chiyero chekuchengetedza mvura yakakwira, kunamatira kwakasimba, kusiri chepfu, kusakuvadza, kuchengetedzeka uye kushamwaridzana. Yakakodzera kugadzirwa kweakajairwa masonry, kupurasita, pasi uye dhaka risingapinde mvura mumafekitori akasanganiswa edhaka, uye rinoshandiswa mukuvaka zvidhinha zvekongiri yevhu, zvidhinha zveceramsite, zvidhinha zvisina mhango, zvidhinha zvekongiri, uye zvidhinha zvisiri zvekupisa zvakasiyana. zvivako zvemaindasitiri nevagari vemo. Kuvakwa kwemukati nekunze kwemadziro emadziro, kongiri yakapfava madziro emadziro, pasi, kuyera denga, dhaka risina mvura, nezvimwe.
1. Cellulose ether
Mudhaka rakagadzirwa,cellulose etherchinhu chikuru chekuwedzera icho chinowedzerwa padanho rakaderera, asi chinogona kuvandudza zvakanyanya zvimiro zvedhaka rakanyorova uye kukanganisa maitiro ekuvaka edhaka. Kusarudzwa kunonzwisisika kwema cellulose ethers emhando dzakasiyana, viscosities dzakasiyana, akasiyana particle saizi, akasiyana viscosity madhigirii uye huwandu hwekuwedzera huchave nemhedzisiro yakanaka pakuvandudzwa kwekuita kwe.dhaka rakaoma.
Mukugadzirwa kwezvinhu zvekuvaka, kunyanya dhaka rakaoma, cellulose ether inoita basa risingadzokerike, kunyanya mukugadzirwa kwedhaka rakakosha (yakagadziridzwa dhaka), chikamu chakakosha uye chakakosha. Cellulose ether inoita basa rekuchengetedza mvura, kukora, kunonoka simende hydration simba, uye kunatsiridza mashandiro ekuvaka. Yakanaka kuchengetedza mvura inoita kuti simende hydration iwedzere kuzara, iyo inogona kuvandudza yakanyorova viscosity yedhaka rakanyorova, kuvandudza chisungo chesimba redhaka, uye inogona kugadzirisa nguva yekushanda. Kuwedzerwa kwe cellulose ethers kune mechanical spray mortars kunogona kuvandudza kupfapfaidza kana kupomba zvimiro zvedhaka, pamwe nekusimba kwechimiro. Naizvozvo, cellulose ether iri kushandiswa zvakanyanya sechinhu chakakosha chekuwedzera mune yakagadzirira-yakasanganiswa dhaka.
2. Redispersible polymer hupfu
Redispersible latex podai powdery thermoplastic resin inowanikwa nekupfapfaidza kuomesa uye kunotevera kugadzirisa kwepolymer emulsion. Inonyanya kushandiswa pakuvaka, kunyanya yakaoma poda dhaka kuwedzerakubatana, kubatana uye kushanduka.
Basa re redispersible latex poda mudhaka: mushure mekupararira kweredispersible polymer poda, inoumba firimu uye inoita sechipiri chekunamatira kuti iwedzere kunamatira; iyo inodzivirira colloid inobatwa nedhaka system uye haizoparadzwi nemvura mushure mekugadzirwa kwemafirimu kana kupararira kwechipiri; iyo firimu-inogadzira polymer resin inogoverwa mukati medhaka system sechinhu chinosimbisa, nekudaro ichiwedzera kubatanidzwa kwedhaka.
Mudhaka rakanyorova, inorasika yepolymer poda inogona kuvandudza mashandiro ekuvaka, kunatsiridza kuyerera, kuwedzera thixotropy uye sag kuramba, kunatsiridza kubatana, kurebesa nguva yekuvhura, uye kuwedzera kuchengetwa kwemvura. Mushure mekunge dhaka rapora, rinogona kuvandudza simba rekusimba. Kusimba kwesimba, kukwidziridzwa kusimba kwesimba, kuderera elastic modulus, kuwedzera deformability, yakawedzera density yezvinhu, kuwedzera kupfeka kuramba, kuwedzera kusimba kwakabatana, kuderera kwekabhoni kudzika, kuderera kwekunyudza kwemvura, uye kuita kuti zvinhu zvive zvakanyanya pfuma yehydrophobic uye zvichingodaro.
Air-entraining agent, inozivikanwawo seaerating agent, inoreva kuunzwa kwenhamba huru yemabhuru madiki akagovaniswa zvakaenzana mukuita kwekusanganiswa kwedhaka, izvo zvinogona kuderedza kusagadzikana kwepamusoro pemvura mudhaka, zvichikonzera kupararira kuri nani uye. kuderedza musanganiswa wedhaka. Additives ekubuda ropa uye kupatsanurwa. Mukuwedzera, kuiswa kwemabhururu emhepo akanaka uye akagadzikana anovandudzawo kushanda. Huwandu hwemhepo hwakaunzwa hunoenderana nerudzi rwedhaka uye midziyo yekusanganisa inoshandiswa.
Kunyange zvazvo huwandu hwemhepo-entraining agent huri huduku zvikuru, mhepo inopinda mumhepo ine simba guru pakuita kwedhaka rakagadzirira-yakasanganiswa. Inogona kunyatso kuvandudza kushanda kwedhaka rakagadzirwa-yakasanganiswa, kuvandudza kusamira uye chando kuramba chedhaka, uye kuderedza density yedhaka. , chengetedza zvinhu uye uwedzere nzvimbo yekuvaka, asi kuwedzerwa kwemhepo-inopinza mumiririri kunoderedza simba redhaka, kunyanya dhaka risingaiti. Nokudaro, chiyero chemhepo-entraining agent inofanira kunyatsodzorwa, uye mhepo yemhepo yevhu, kushanda kwekuvaka uye Simba rekuenzanisa kuti rione huwandu hwakakwana hwekuwedzera.
4. Mumiriri wesimba rekutanga
Iyo yekutanga simba mumiriri ndeyekuwedzera iyo inogona kukurumidzira kusimudzira kwekutanga kwesimba rematope. Mazhinji acho inorganic electrolytes, uye mashoma ari organic komisheni.
Iyo yekutanga simba mumiriri weyakagadzirira-yakasanganiswa dhaka inodiwa kuve hupfu uye yakaoma. Calcium formate ndiyo inonyanya kushandiswa mudhaka rakagadzirwa-yakasanganiswa. Calcium formate inogona kuvandudza simba rekutanga redhaka uye nekumhanyisa hydration ye tricalcium silicate, ine imwe mhedzisiro yekudzikisa mvura, uye hunhu hwekarusiyamu formate hwakagadzikana pakupisa kwekamuri. Hazvisi nyore kuita agglomerate, uye inonyanya kukodzera kushandiswa mune yakaoma poda dhaka.
5. Mvura inoderedza mumiririri
Mvura inoderedza mumiriririinoreva chimwe chinowedzera chinogona kuderedza kuwanda kwekuvhenganisa mvura pasi pemamiriro ekuti kuwirirana kwedhaka kwakafanana.Superplasticizersanowanzo surfactants, ayo anogona kukamurwa kuita: akajairwa superplasticizers, superplasticizers, ekutanga-simba superplasticizers, kudzoreredza superplasticizers, kudzoreredza superplasticizers, uye superplasticizers zvinoenderana nemabasa avo.
Iyo yekudzikisa mvura inoshandiswa kugadzira yakasanganiswa dhaka inodiwa kuti ive upfu uye yakaoma. Mushonga wakadaro unoderedza mvura unogona kuparadzirwa zvakafanana mumatope akaoma pasina kuderedza hupenyu hwesherufu yedhaka rakagadzirwa. Parizvino, kushandiswa kwekudzikisa mvura mudhaka yakagadzirira-yakasanganiswa kazhinji mune simende self-leveling, gypsum self-leveling, batch scraping mortar, waterproof dhaka, putty, nezvimwewo. zvakasiyana dhaka zvivakwa. optional.
Yakagadzirira-yakasanganiswa dhaka additives inosanganisirawo retarders, accelerators,fibers, thixotropic lubricants, defoaming agents, nezvimwewo, izvo zvinowedzerwa maererano nemhando dzakasiyana dzematope. Izvi zvinowedzera zvinoshandiswa mudhaka rakagadzirwa-musanganiswa kuunza kuvandudzwa kwekuita kwakafanana nekurunga kwekubikisa chikafu. Inowedzerwa mundiro kuti ijekese ruvara rwendiro, kuwedzera kuravira, uye kuvhara chikafu, kuitira kuti marudzi akasiyana eakagadzirira-akasanganiswa madhakaanogona kuita basa riri nani. Chombo chemashiripiti chekushandisa zvirinani mumapurojekiti akaoma akasanganiswa edhaka.
