Incamake yo Kwishyira hamwe

Kwishyira hamwe-ibikoresho, ibikoresho byingenzi mubwubatsi bugezweho bwubatswe, mubusanzwe bikozwe muri sima ya Portland, igiteranyo cyiza, polymers ikora, ninyongera zidasanzwe. Umutungo wabo wihariye wo kuringaniza ibintu ukomoka kumurongo mwinshi utemba wakozwe nyuma yo kuvanga, ushobora guhita uringaniza munsi yuburemere kugirango habeho urufatiro rworoshye hamwe nubunini buri hagati ya 3mm na 50mm.

Porogaramu zisanzwe zirimo inganda zinganda (urugero, amagorofa-yuzuye neza mumahugurwa yo gukora amamodoka), ahantu h'ubucuruzi (urugero, ahantu hanini cyane-idashobora kwihanganira kwambara mumasoko manini manini), hamwe nimishinga yo murwego rwohejuru (urugero, kuringaniza ibice bya sisitemu yo gushyushya hasi).

Ibyiza byo kubaka

Ugereranije na gakondo ya minisiteri iringaniza, ibice byo kwishyira hamwe byongera ubwubatsi 40% -60%. Uburyo bwabo bwo gukira bwihuse bugabanya cyane igihe cyumushinga, bigatuma biba byiza "kubaka ijoro - gutanga umunsi ukurikira" mubikorwa byo kuvugurura.

Kuki ukoresha HPMC murwego rwo Kwishyira hamwe? Nigute Imikorere?

a. Amabwiriza yo Kubungabunga Amazi

HPMC molekules itanga amazi binyuze mumigozi ya hydrogène, ikora umuyoboro wibice bitatu byongera amazi ya minisiteri kugeza kuri 90% (ugereranije na 75% nta HPMC). Ahantu h’ubushyuhe bwo hejuru (> 30 ° C), guhitamo HPMC hamwe nubushyuhe bwa gelation ≥65 ° C bidindiza guhumeka amazi, bikarinda gutakaza imbaraga kubera hydrata idahagije.

b. Gukwirakwiza umutungo wa Rheologiya

• Kugenzura imigezi. ubwoko bwubwiza bwinshi (urugero, 15000Mpas) byongera thixotropy, bikarinda imyanda yose hamwe mubwubatsi bwimbitse (10-50mm) kugirango habeho ubucucike bumwe.

• Ingaruka zo Guhuza: Iyo wongeyeho hamwe na polycarboxylate igabanya amazi, HPMC ibuza gutandukanya. Kuri 0.3% igabanya amazi na 0.12% HPMC, gutakaza iminota 30 yo gutemba ≤10%, byujuje ibisabwa biterwa nigihe cyo kwishyiriraho.

c. Kugabanuka no Kuvunika

Mugutinza amazi ya sima (kongera igihe cyambere cyo gushiraho iminota 15-30), HPMC igabanya imihangayiko yo kugabanuka hakiri kare 30%.Mu gukama ibizamini byo kugabanuka, minisiteri hamwe na HPMC yerekana igipimo cyiminsi 28 cyo kugabanuka kwa 0.018%, kiri munsi ya 0.035% kuburugero rutari HPMC, bigabanya neza gucika mikorobe.

Nigute ushobora guhitamo HPMC ibereye kugirango ihuze na Self-Leveling Compound Construction Scenario?

Inganda zo mu rwego rwa HPMC zashyizwe mu majwi nubwiza bwibisubizo byabo byamazi 2% muburyo buke buke ( 30000Mpas), bwujuje ibyangombwa bitandukanye byubaka.

Ibipimo by'ingenziKubyubaka bitandukanyeUrugero

Urugero rwo Gushiraho (Gypsumu-Yishingiye-Kwishyira hamwe):Ibigize shingiro: α-hemihydrate gypsum 60%, calcium karubone 30%, umucanga wa quartz (mesh 80-120 mesh) 10%; Inyongeramusaruro: HPMC (20000mPa · s, 0.18%), retarder (aside tartaric, 0,05%), kugabanya amazi (ishingiye kuri melamine, 0.3%.(Ibi nibisobanuro byawe gusa) 

Umwanzuro

Nkibikorwa byingenzi byongeweho muburyo bwo kuringaniza ibice,HPMCIhindura imikorere yibikorwa mugihe cyo kwitegura, kubaka, no mubuzima bwa serivisi. Hamwe no gukenera ibisabwa kugirango hubakwe inganda mu kubaka inganda,HPMCguhitamo no gukoresha tekinoroji bizarushaho kunonosorwa kandi bifite ubwenge.
