I-2021 China New Design Microspheres Powder For Cement Slurries - Ama-microspheres engilazi angenalutho okugcwalisa upende – Kehui

Ama-microsphere engilazi angenalutho angama-microsphere engilazi anobukhulu obuphansi, isisindo esincane kanye namandla aphezulu. Ngenxa yezici ezingenalutho, uma kuqhathaniswa nobuhlalu beglasi obujwayelekile, inezici zesisindo esilula, ubukhulu obuphansi kanye nokusebenza kahle kokushisa. Le ndlela ingezwa ngqo ohlelweni lokumboza, ukuze ifilimu yokumboza eyakhiwe ngokuqina kwengubo ibe nezakhiwo zokushisa. Ngaphezu kokumuncwa kwayo okuphansi kwamafutha kanye nobukhulu obuphansi, ukwengeza u-5% (wt) kungandisa umkhiqizo oqediwe ngo-25% kuya ku-35%, ngaleyo ndlela kungakhulisi noma kunciphise izindleko zevolumu yeyunithi yengubo.
Ama-microsphere engilazi angenalutho ayizindilinga ezivaliwe ezingenalutho, ezifakwa embozweni ukuze zakhe imigodi eminingi yokushisa ezimele engabonakali, ngaleyo ndlela zithuthukisa kakhulu ukufudumala kwefilimu yokugqoka ngokumelene nokushisa nomsindo futhi zidlala indima enhle ekushiseni nasekunciphiseni umsindo. Yenza ukugqoka kube nezakhiwo ezingangeni manzi, ezilwa nokungcola kanye nezokulwa nokugqwala. Ubuso obungenawo amakhemikhali bama-microbeads bumelana nokugqwala kwamakhemikhali. Lapho ifilimu yakheka, izinhlayiya ze- ama-microbead engilazi zihlelwe eduze ukuze zakhe i-porosity ephansi, ukuze ubuso bokumboza bakhe ifilimu evikelayo enomphumela wokuvimba umswakama nama-ion agqwalisayo, okudlala indima enhle ekuvikeleni.

Isakhiwo esiyindilinga sama-glass beads angenalutho senza sibe nomthelela omuhle wokusabalala emandleni okushaya kanye nokucindezeleka. Ukuyifaka ephepheni kungathuthukisa ukumelana komthelela wefilimu yokumboza futhi kunganciphisa nokwanda kokushisa kanye nokufinyela kokugqoka.

Umphumela omuhle wokwenza mhlophe kanye nomthunzi. Impuphu emhlophe inomphumela omuhle wokwenza mhlophe kunemibala evamile, inciphisa ngempumelelo inani lezinye izigcwalisi ezibizayo kanye nemibala (uma kuqhathaniswa ne-titanium dioxide, ivolumu yezindleko zama-microbeads cishe iyi-1/5 kuphela) Ithuthukisa ngempumelelo ukunamathela kokugxila kokumboza. Izici eziphansi zokumunca uwoyela zama-microbeads engilazi zivumela i-resin eningi ukuthi ihlanganyele ekwakhiweni kwefilimu, ngaleyo ndlela ikhulisa ukunamathela kokumboza izikhathi ezi-3 kuya kwezi-4.

Ukwengeza u-5% wama-microbeads kungenza ubuningi be-coating busuke ku-1.30 bube ngaphansi kuka-1.0, ngaleyo ndlela kunciphisa kakhulu isisindo se-coating futhi kugwemeke ukuthi i-coating yodonga ihlubuke.

Ama-microbeads anomthelela omuhle wokukhanya emisebeni ye-ultraviolet, evimbela ungqimba ukuthi lungabi phuzi futhi luguge.

Indawo ephezulu yokuncibilika kwama-microbeads ithuthukisa kakhulu ukumelana nokushisa kwengubo futhi idlala indima enhle kakhulu ekuvimbeleni umlilo. Izinhlayiya eziyindilinga zama-microbeads zidlala indima yama-bearings, futhi amandla okungqubuzana mancane, okungathuthukisa ukusebenza kwengubo yokugeleza futhi kwenze ukwakhiwa kube lula kakhudlwana.

Izincomo zokusetshenziswa: Inani elijwayelekile lokwengeza lingu-10% wesisindo sonke. Ama-microbead alungiswa ebusweni futhi anobuningi obuphansi, okwenza uqweqwe luthambekele ekwandeni kwe-viscosity nokuntanta ngesikhathi sokugcina. Sincoma ukwandisa i-viscosity yokuqala yoqweqwe (ngokwandisa inani elengeziwe le-thickener lilawula i-viscosity engaphezu kuka-140KU), kulokhu, lesi simo esintantayo ngeke senzeke ngoba i-viscosity iphansi kakhulu, futhi izinhlayiya zezinto ngazinye ohlelweni zincishisiwe emsebenzini ngenxa ye-viscosity ephezulu, okuzuzisa ukulawula i-viscosity. Sincoma kakhulu indlela elandelayo yokwengeza: ngoba ama-microbead anezindonga ezincane zezinhlayiya kanye nokumelana okuphansi kokucheba, ukuze kusetshenziswe ngokugcwele izici ezingenalutho zama-microbeads, kunconywa ukuthi kuthathwe indlela yokugcina yokwengeza, okungukuthi, faka ama-microbeads ekugcineni koqweqwe. Ukwengeza kuhlakazwa ngemishini yokuxuba ngesivinini esiphansi kanye namandla aphansi okucheba ngangokunokwenzeka. Ngenxa yokuthi ukuma kwe-spherical kwama-microbeads kunokuguquguquka okuhle futhi ukungqubuzana phakathi kwawo akukukhulu, kulula ukuhlakazeka. Ingamanziswa ngokuphelele ngesikhathi esifushane, vele nje yandise isikhathi sokuxuba ukuze kutholakale ukuhlakazeka okufanayo.

Ama-microbead awasebenzi ngamakhemikhali futhi awanobuthi. Kodwa-ke, ngenxa yesisindo sawo esilula kakhulu, kudingeka ukunakekelwa okukhethekile lapho uwafaka. Sincoma indlela yokwengeza isinyathelo ngesinyathelo, okungukuthi, inani lokwengeza ngakunye liyi-1/2 yama-microbead asele, futhi afakwe kancane kancane, okungavimbela kangcono ama-microbead ukuthi antante emoyeni futhi kwenze ukuhlakazeka kuphelele.
