Zviwedzeredzo zvakagadziridzwa senge zvakagadzirirwa-zvakasanganiswa dhaka additives, cellulose ethers, coagulation regulators, redispersible latex poda, air-entraining agents, maajenti ekutanga simba, zvinoderedza mvura, nezvimwewo, izvo zvinowedzerwa zvinoenderana nezvinodiwa zvepurojekiti, zvinovandudza zvakanyanya mashandiro ematokari akagadzirira-akasanganiswa. Zvenyama uye zvemagetsi zvivakwa.
1. Yakagadzirira-yakasanganiswa dhaka additive
Iyo anionic surfactant iri mune yakagadzirira-yakasanganiswa dhaka yekuwedzera mupurojekiti inogona kuita kuti masimende zvipararire, kusunungura mvura yemahara yakavharidzirwa nesamende aggregate, kuparadzira zvizere simende yakaunganidzwa, uye yakazara hydrate kuti iwane compact chimiro uye kuwedzera dhaka density. Simba, kunatsiridza kusamira, kutsemuka kuramba uye kusimba. Iyo dhaka yakavhenganiswa neyakagadzirirwa-yakasanganiswa yedhaka additives ine yakanaka kushanda, yakakwirira yekuchengeta mvura mwero, yakasimba yakabatana simba, isiri-chepfu, isingakuvadzi, yakachengeteka uye yakatenderedza nharaunda panguva yekushanda. Yakakodzera kugadzirwa kweakajairwa masonry, kupurasita, pasi, uye dhaka risingapinde mvura mumafekitori akasanganiswa edhaka. Inoshandiswa kugadzira uye kuvaka kwekongiri yevhu zvidhinha, zvidhinha zveceramsite, zvidhinha zvisina mhango, zvidhinha zvekongiri, zvidhinha zvisina kupiswa muzvivakwa zvakasiyana siyana zveindasitiri nevagari. Kuvakwa kwemukati nekunze kwemadziro emadziro, kongiri madziro plastering, pasi uye denga rekuyera, dhaka risina mvura, nezvimwe.
2. Cellulose ether
Mune yakagadzirira-yakasanganiswa dhaka, cellulose ether ndiyo huru yekuwedzera iyo inogona zvakanyanya kuvandudza mashandiro edhaka rakanyorova uye kukanganisa kushanda kwekuvaka kwedhaka. Kusarudzwa kunonzwisisika kwema cellulose ethers emhando dzakasiyana-siyana, viscosities dzakasiyana, zvakasiyana-siyana zvidimbu, madhigirii akasiyana-siyana eviscosity uye yakawedzerwa mari ichava nemigumisiro yakanaka pakuvandudzwa kwekushanda kwevhu rakaoma dhaka.
Kugadzirwa kwe cellulose ether kunonyanya kugadzirwa neakasikwa fibers kuburikidza nealkali dissolution, grafting reaction (etherification), kugeza, kuomesa, kunyudza uye mamwe maitiro. Mukugadzirwa kwezvinhu zvekuvaka, kunyanya yakaoma poda dhaka, cellulose ether inoita basa risingadzoreki, kunyanya mukugadzirwa kwedhaka rakakosha (yakagadziridzwa dhaka), chinhu chakakosha uye chakakosha chikamu. Cellulose ether inoita basa rekuchengetedza mvura, kukora, kunonoka simende hydration simba, uye kunatsiridza mashandiro ekuvaka. Yakanaka kuchengetedza mvura inoita kuti simende hydration iwedzere kuzara, inogona kuvandudza yakanyorova viscosity yedhaka rakanyorova, kuwedzera simba rekubatanidza redhaka, uye kugadzirisa nguva. Kuwedzera cellulose ether kune mechanic yekupfapfaidza dhaka kunogona kuvandudza kupfapfaidza kana kupomba kuita uye kusimba kwechimiro chedhaka. Naizvozvo, cellulose ether iri kushandiswa zvakanyanya sechinhu chakakosha chekuwedzera mudhaka rakagadzirwa-musanganiswa. Macellulose ethers anoshandiswa mudhaka yakasanganiswa anonyanya kuve methyl hydroxyethyl cellulose ether uye methyl hydroxypropyl cellulose ether. , vanotora zvinopfuura 90% yemugove wemusika.
3. Redispersible latex poda
Redispersible latex poda i powdery thermoplastic resin inowanikwa nekupfapfaidza kuomesa uye kunotevera kugadziridzwa kwepolymer emulsion. Inonyanya kushandiswa pakuvaka, kunyanya yakaoma poda dhaka kuti iwedzere kubatana, kubatana uye kushanduka.
Basa re redispersible latex powder mumatope: redispersible latex powder inoumba firimu mushure mekupararira uye inoita sechipiri chekunamatira kuti chiwedzere kunamatira; iyo inodzivirira colloid inobatwa nedhaka system uye haizoparadzwi nemvura mushure mekuumbwa kwefirimu Kana maviri dispersions; iyo firimu-inogadzira polymer resin inogoverwa mukati medhaka system sechinhu chinosimbisa, nekudaro ichiwedzera kubatanidzwa kwedhaka.
Redispersible latex powder mumatope emvura inogona kuvandudza kushanda kwekuvaka, kunatsiridza kuyerera kwekushanda, kuwedzera thixotropy uye sag resistance, kunatsiridza kubatana, kuwedzera nguva yakazaruka, kuwedzera kuchengetwa kwemvura, nezvimwewo. Kusimba kwesimba, kukwidziridzwa kusimba kwekukotama, kuderedzwa elastic modulus, yakagadziridzwa deformability, yakawedzera zvinhu compactness, yakagadziridzwa kupfeka kuramba, kuvandudzwa kwesimba rakabatana, kuderera kwecarbonization kudzika, kuderedzwa kwemvura kunyura kwechinhu, uye kuita kuti zvinyorwa zvive zvakanakisa kudzoreredza mvura Mvura-yakavakirwa uye zvimwe zvinokonzeresa.
4. Air-entraining agent
Air-entraining agent, inonziwo air-entraining agent, inoreva kuiswa kwenhamba yakawanda yakagoverwa zvakafanana micro-bubbles panguva yekusanganiswa kwevhu, izvo zvinogona kuderedza kushushikana kwepamusoro pemvura mudhaka, zvichiita kuti kupararira kuri nani uye kuderedza musanganiswa wedhaka. Kubuda ropa, kupatsanura zvinowedzera. Mukuwedzera, kuiswa kwemabhururu emhepo akanaka uye akagadzikana anovandudzawo kushanda kwekuvaka. Huwandu hwemhepo hwakaunzwa hunoenderana nerudzi rwedhaka uye midziyo yekusanganisa inoshandiswa.
Kunyangwe huwandu hwemhepo-inopinza mumiriri idiki kwazvo, iyo mhepo-inopinza mumiriri ine simba guru pakuita kwedhaka rakagadzirwa-yakasanganiswa, iro rinogona kuvandudza kushanda kweyakagadzirira-yakavhenganiswa dhaka, kuvandudza kusamira uye chando kuramba kwedhaka, uye kuderedza density yedhaka, chengetedza zvinhu uye kuwedzera nzvimbo yekuvaka, asi kuwedzera kwedhaka remhepo kunoderedza dhaka. Correlation intensity yekuona iyo yakakwana dosage.
5. Mumiriri wesimba rekutanga
Iyo yekutanga simba mumiriri muwedzero unogona kukurumidzira kukura kwesimba rekutanga redhaka, mazhinji acho ari inorganic electrolytes, uye mashoma ari organic makomisheni.
Iyo accelerator yeyakagadzirira-yakasanganiswa dhaka inodiwa kuti ive upfu uye yakaoma. Calcium formate ndiyo inonyanya kushandiswa mudhaka rakagadzirwa-yakasanganiswa. Calcium formate inogona kuvandudza simba rekutanga redhaka, uye nekumhanyisa hydration ye tricalcium silicate, inogona kuderedza mvura kusvika pamwero wakati. Uyezve, izvo zvemuviri zvimiro zvecalcium formate zvakagadzikana pakudziya kwekamuri. Hazvisi nyore kuita agglomerate uye zvakanyanya kukodzera kunyorera muvhu rakaoma dhaka.
6. Water reducer
Mvura inoderedza mumiririri inoreva kuwedzera kunogona kuderedza kuwanda kwekusanganiswa kwemvura pasi pemamiriro ekuchengetedza kuwirirana kwedhaka zvakangofanana. Iyo inodzikisira mvura inowanzo surfactant, iyo inogona kukamurwa kuita yakajairwa mvura inodzikisira, yakanyanya kunaka inodzikisira mvura, yekutanga simba inodzikisira mvura, inodzoreredza mvura inoderedza, inodzoreredza yakakwira inodzikisira mvura uye inoderedza mvura inoderedza zvinoenderana nemabasa avo. .
Iyo inoderedza mvura inoshandiswa kune yakagadzirira-yakasanganiswa dhaka inodiwa kuti ive powdery uye yakaoma. Mvura yakadaro inoderedza mvura inogona kuparadzirwa zvakaenzana mumatope akaoma pasina kuderedza hupenyu hwesherufu yedhaka rakagadzirwa. Parizvino, kushandiswa kwemvura inoderedza mumiririri mudhaka yakakanyiwa inowanzoita sement self-leveling, gypsum self-leveling, plastering dhaka, dhaka risina mvura, putty, nezvimwewo. Sarudza.
