Polycarboxylate superplasticizer imhando nyowani yemvura-yekudzikisa mumiririri yakagadzirwa ne monomer yakawanda-chikamu chemvura-based polymerization mvura inoderedza.Nekuda kweiyo yakasarudzika yemamorekuru chimiro, iyo inoderedza mvura inokwanisa kuona kupararira kwezvimedu zvesimende kuburikidza neaviri chiito che electrostatic repulsion uye steric barriers, ichiratidza yakanakisa dispersibility uye kupararira kugona kuchengetedza.Ichi chigadzirwa chine mabhenefiti eiyo yakaderera dosage, yakakwira yekudzikisa mvura mwero, yakanaka yekusimbisa mhedzisiro, yakaderera yakazara alkali yemukati, isiri-corrosion yemasimbi simbi uye kushamwaridzana kwezvakatipoteredza.Chizvarwa chechitatu chepamusoro-chekuita chekudzikisa mvura chakagadziridzwa mushure memugadziri wekudzikisa mvura pari zvino ndiye akanyanya kunyanyisa kuderedza mvura pasi rose, ane ruzivo rwepamusoro-soro rwetekinoroji, tarisiro yakanakisa yekushandisa uye yakanakisa mashandiro akazara.
Polycarboxylate superplasticizer ine zvirinani kuchengetedza pasi pemamiriro ekugadzirisa kwakanaka kune zvinhu zvinoshandiswa.
Iko kurasikirwa kwekongiri mu1.5h idiki kwazvo, kazhinji haipfuuri 15%, iyo inobatsira zvakanyanya pakufambisa kureba kwekongiri.
Musanganiswa wekongiri wakagadzirwa nepolycarboxylate superplasticizer une kugona basa kwakanaka uye kubatana kwakanaka.
Iine zvimwe zvinhu zvinovaraidza mhepo, izvo zvinogona kuwedzera mhepo yekongiri inodarika 2%.
Shanduko yereshiyo yekusanganisa ine imwe pesvedzero pamhepo inovaraidza pfuma yepolycarboxylate superplasticizer, uye kuwedzera kwemukati wemhepo hakuna mhedzisiro yakaipa pasimba.
Iine simba rekusimbisa rakanaka pane yakaomeswa kongiri, uye kukura kwesimba kwakagadzikana, kazhinji mazuva manomwe
Simba rinogona kusvika ku100% yesimba rekugadzira, uye simba rinoramba richiwedzera muchikamu chekupedzisira.
Iyo molecular chimiro ine hukuru hukuru hwerusununguko, uye kune akawanda anodzoreka paramita mune yekuwedzera yekugadzira tekinoroji.
Polycarboxylate superplasticizers ine yakakosha zvivakwa uye mashandisiro anogona kugadzirwa nekugadzirisa mamorekuru chimiro, chiri nyore kusangana nezvinodiwa zvekuchinja kwezvakatipoteredza panzvimbo yekuvaka.
Chigadzirwa chacho chakasvibirira uye chinoenderana nemamiriro ekunze, uye hachina zvinhu zvinokuvadza zvinosvibisa nharaunda uye zvinokanganisa hutano hwevanhu.
Zvakanakira zvepolycarboxylate superplasticizers zviri pachena kune vese, zvisingaenzaniswi nemamwe marudzi e superplasticizers.Chero bedzi isu tichitarisa matambudziko aya kubva kune yakarongeka uye yekusimudzira maonero, simbisa kudyidzana uye kurongeka pakati pevagadziri uye vashandisi ve superplasticizers, kusanganisira vanogadzira simende, ipai kutamba kwakazara kune zvakanakira polycarboxylate superplasticizers, uye edza kukunda zvikanganiso zvavo. tarisiro yepolycarboxylate superplasticizer ichave yakakura.
