Mhedziso yeSelf-Leveling Compound

Kuzvimisikidza komisheni, zvinhu zvakakosha muinjiniya yekuvaka pasi, zvinowanzo gadzirwa kubva kuPortland simende, akaunganidzwa akakwana, anoshanda mapolima, uye hunyanzvi hwekuwedzera. Nzvimbo yavo yakasarudzika yekuzvimiririra inomuka kubva kune yakakwira-fluidity slurry yakaumbwa mushure mekusanganiswa, iyo inogona kungoerekana yadzika pasi pegiravhiti kugadzira mabhesi akatsetseka ane ukobvu kubva pa3mm kusvika 50mm.

Zvishandiso zvakajairika zvinosanganisira zvirimwa zvemaindasitiri (semuenzaniso, uriri hwepamusoro-soro mumashopu ekugadzira mota), nzvimbo dzekutengesa (semuenzaniso, nzvimbo huru-isingapfeki uriri muzvitoro zvikuru), uye mapurojekiti ekugara epamusoro (semuenzaniso, mitsara yekuyera yepasi pepasi).

Kuvaka Zvakanakira

Kuenzaniswa nemaitiro echinyakare ekuyeresa dhaka, maumbirwo ega ega anowedzera kushanda kwekuvaka ne40% -60%. Chimiro chavo chekukurumidza kurapa chinopfupisa nguva yeprojekiti, zvichiita kuti ive yakanakira "kuvaka kwehusiku-zuva rinotevera kuendesa" zviitiko mumapurojekiti ekugadzirisa.

Sei uchishandisa HPMC muSelf-Leveling Compound? Ko Performance iri sei?

a. Kuchengeta Mvura Regulation

HPMC mamorekuru adsorb mvura kuburikidza nehydrogen bond, achigadzira matatu-dimensional network inowedzera dhaka rekuchengetedza mvura kusvika pamusoro pe90% (ichienzaniswa ne75% isina HPMC). Munzvimbo dzepamusoro-soro (> 30 ° C), kusarudza HPMC ine gelation tembiricha ≥65 ° C inononoka kubuda kwemvura, kudzivirira kurasikirwa kwesimba nekuda kwekusakwana simende hydration.

b. Rheological Property Optimization

• Kudzora Kuyerera: Low-viscosity HPMC (semuenzaniso, 400Mpas) inoderedza kushushikana kwegoho, kubudirira kwekutanga kuyerera kwe180-220mm kune yakaonda-layer self-leveling (3-5mm); mhando dzepamusoro-viscosity (semuenzaniso, 15000Mpas) inosimudzira thixotropy, kudzivirira aggregate sedimentation mune gobvu-layer kuvaka (10-50mm) kuve nechokwadi yunifomu density.

• Synergistic Mhedzisiro: Kana yakasanganiswa ne polycarboxylate mvura inoderedza, HPMC inodzivisa kusarura. Pa 0.3% mvura inoderedza uye 0.12% HPMC, iyo 30-maminetsi ekuyerera kurasikirwa ≤10%, kusangana nenguva-inotsamira kuyerera kwezvinodiwa zvekuzvimiririra.

c. Shrinkage uye Cracking Inhibition

Nekunonotsa simende hydration (kurebesa nguva yekutanga kuseta nemaminetsi gumi nemashanu-30), HPMC inoderedza kukurumidza shrinkage kushushikana nepamusoro pe30%.Mukuomesa shrinkage bvunzo, madhaka ane HPMC anoratidza 28-day shrinkage rate ye0.018%, yakaderera zvakanyanya pane 0.035% yeasiri-HPMC samples, zvinobudirira kuderedza micro-cracking.

Maitiro ekusarudza iyo chaiyo HPMC kuti ienderane akasiyana Self-Leveling Compound Constructions Scenario?

Indasitiri-giredhi HPMC inoiswa neiyo viscosity yavo 2% aqueous mhinduro mune yakaderera-viscosity ( 30000Mpas) mhando, ichipa kune zvakasiyana zvinodiwa zvekuvaka.
