Kodi ndi chisankho chiti chomwe chingakulepheretse kukhazikika kwa simenti? (Hpmc)

HydroxypropymethylCelose (hpmc) ndi gawo losiyanasiyana lomwe limagwiritsidwa ntchito pomanga, kuphatikizapo mapangidwe a konkriti. Ngakhale sizingathandize molondola kulimba kwa konkriti, imagwira ntchito yofunika kwambiri yokonza zinthu zosiyanasiyana za kusakaniza konkriti.

1. Kuyambitsa kwa hydroxypropyl methylcellulose:

Hydroxypypyl methylcellulose (hpmc) ndi etherle yosinthidwa kuchokera ku ma polima achilengedwe. Chifukwa cha zovuta zake zapadera, zimagwiritsidwa ntchito kwambiri ngati zowonjezera pamatongani. Ku Concerete, hpmc nthawi zambiri amagwiritsidwa ntchito ngati wothandizira madzi, wokulirapo, ndi binder. Kapangidwe kake kamathandiza kuti apange filimu yoteteza mozungulira cemements, akukhudza zojambula zamtundu wazosasinthasintha.

2. The Udindo wa HPMC mu Condiclity:

Kusunga kwamadzi komanso kugwirira ntchito:

HPMC imagwira ngati mwayi wololera madzi, kupewa kutaya madzi ambiri kumayambiriro kwa kuvala konkriti.
Kusungidwa kwamphamvu kwamadzi kumathandiza kukhalabe othandiza kwambiri, chifukwa choyikapo konkriti.

Kupititsa patsogolo:

Katundu wopanga chithandizo HPMC amathandizira kutsatira pakati pa simenti pakati pa simenti, zomwe zimapangitsa matrix ogwirizana komanso olimba.

Chepetsani kupatukana ndi magazi:

HPMC imathandizira kuchepetsa chiopsezo cha tsankho komanso magazi mu zosakaniza ndi konkriti, zomwe zimapangitsa kuti mudziwe zambiri, zolimbitsa thupi.

Nthawi Yabwino Yokhazikika:

Kugwiritsa ntchito HPMC kungapangitse kukhazikika kwa konkriti, potero kumapereka mwayi pakati pa kugwirira ntchito komanso kupitilizidwa kukula.

Zotsatira zamakina:

Ngakhale HPMC yokha siyingakuthandizeni mwachindunji kukhazikika kwa konkriti, kumathandizanso pakugwiritsa ntchito konkriti kosagwirizana ndi makina opanga konkriti, kuthandiza kupanga zolimba komanso zolimba.

3. Zolemba ndi machitidwe abwino:

Mlingo:

Mlingo woyenera wa HPMC ndiwotsutsa. Kugwiritsa ntchito bongo kumatha kuyambitsa mavuto, pomwe kudana mtima sikungapereke kusintha.

Kugwirizana:

Kugwirizana ndi Adretective Andrectures ndi zida ziyenera kuganiziridwa kuti zisachitike zovuta zomwe zingasokoneze zinthu zosakaniza.

Njira yochiririra:

Ngakhale HPMC imathandizira kusunga madzi, njira zoyenera zochiritsira ziyenera kugwiritsidwa ntchito potsimikizira kulimba kwa konkriti kwa nthawi yayitali.

Ngakhale HPMC si Mthandizi mwachindunji yemwe amathandizira kulimba kwa konkriti, kugwiritsa ntchito zinthu zosakanikirana ndi ma conthete amatha kusintha mokhazikika, ndipo pali zinthu zina, potengera kusinthasintha kokhazikika kwa ma cobretive. HPMC iyenera kuonedwa ngati gawo la njira yophatikizira kupita ku mapangidwe a konkriti osakaniza ndi zomangira zomangira kuti mukwaniritse zolimba komanso zotsalira.
