Kupanga zida zowonjezera ma cecker hpmc

Mu zomangamanga, konkriti imayima ngati mwala wapadziko lonse, kupereka maziko, komanso mphamvu. Komabe, chotheka cha konkriti nthawi zambiri chimakhazikika pakuphatikiza zowonjezera zomwe zimapangitsa kuti katundu wake uwonjezere. Hydroxypylmmyl methylcellulose (hpmc) imatuluka ngati chowonjezera chowonjezera, makamaka chodalirika monga chonkriti.

1.Proteries ya HPMC:

Hydroxypropyl methylcellulose, etherse yopanda etherose eyityd kuchokera ku ma polima, omwe amadzitamandira kuti azikhala ndi mwayi wokhala ndi ma konkreti Makhalidwe abwino amaphatikizapo:
Kusunga kwamadzi: hydcc's hydrophiric chilengedwe chilili gwiritsitsani madzi mkati mwazosakaniza, onetsetsani kuti ndi yothandiza.
Kusintha kwa Rhelogy: HPMC imagwira ngati yotsitsimutsa mwa kusintha kadongosolo ka konkriti kwa konkriti, kukulitsa mgwirizano wake ndikuchepetsa tsankho.
Zotsatsa: Zimalimbikitsa kutsatira pakati pa tinthu tambiri tinthu tambiri ndi zina, kukulitsa mphamvu zambiri ndi kukhulupirika kwa ziwonetsero za konkriti.
Kukhazikitsa Kuwongolera: HPMC imathandizira kuwongolera nthawi yayitali pa nthawi ya konkriti, kulola kusintha kogwirizana ndi zofunikira pa polojekiti.
Kugwiritsa ntchito kugwirira ntchito mafuta: popatsa mafuta komanso kuchepetsa kukangana, hpmc kumathandizira kugwiritsidwa ntchito kwa zosakanikirana kwa zosakanikirana kwa ma crerete, kuwongolera kosavuta kuyika ndikuphatikizana.

2.Paplication ya HPMC mu konkriti:

Kusintha kwa HPMC kumapangitsa kuti pakhale koyenera pamapulogalamu ena a konkriti, kuphatikiza koma osangokhala:
Kudzilimbitsa nokha: HPMC imathandizira kusintha kwa zozinukira zongolimbitsa thupi konkriti, ndikuwonetsetsa osalala komanso osasunthika kuti azigwiritsa ntchito pansi.
Matope ndipo amapereka mavalo ndipo amapereka ndalama, kutsatsa kwa HPMC kumakhala kovuta kwambiri, kothandiza, kuchepetsa, ndikusintha kutsatira shriets.
Tsitsi loti:
Shotcrete: Mapulogalamu owombera mfuti, hpmc amasintha coutheon ndikuchepetsa kubwezeretsa, ndikuonetsetsa kuti kulimbikira ndi kokhazikika komanso kokhazikika.
Kukonza ndi kubwezeretsa matope owongolera matope owonetsa kuwunikira malo ophatikizika, otsogolera kukonzanso bwino komanso ntchito yobwezeretsa.

Mapa 1.

Kugwiritsa ntchito kwa HPMC ngati konkriti konkriti kuwonetsa zabwino zambiri, kuphatikizapo:
Kuthandiza Kuchita Zinthu: HPMC imathandizira kugwiritsidwa ntchito kwa zosakanikirana kwa ma crerete, kulola kuti azigwira bwino ntchito komanso kuyikamo ndalama, potero kuchepetsa ndalama ndi nthawi.
Kusasinthika: Popanga kufanana kwa zosakanikirana kwa zitsulo za siteri, HPMC zimawonetsa magwiridwe antchito komanso ntchito yomanga.
Kukhazikika: Kuphatikizika kwa HPMC kumathandizira kulimba kwa ma conrete ma contictive pochepetsa kusokonezeka, shrinkage, komanso tsankho.
Kukhazikika kwachilengedwe: Monga zowonjezera zochokera ku Cellulose zochokera ku magwero osinthidwa, hpmc mogwirizana ndi zochitika zomangamanga, zimathandizira utsogoleri wa chilengedwe.
Kugwira Bwino: Ngakhale kuti pali zopindulitsa, hpmc zimangokhala zotsika mtengo chifukwa cha kuthekera kwake kokweza maluso a konkriti ndikuchepetsa kufunikira kwa zowonjezera kapena njira zowonjezera.

Hydroxypylropyl imatuluka ngati yothandiza komanso yofunika kwambiri pakupanga konkriti yamakono, makamaka yamtengo wapatali chifukwa cha gawo lake ngati konkriti. Malo ake apadera, ntchito zosiyanasiyana, komanso ubwino wachilengedwe umatsirizira kufunika kwake pakulimbitsa magwiridwe antchito, kugwirira ntchito, komanso kukhazikika kwa ma cokistreti. Monga njira zomangira zoyendera zimasinthira bwino komanso kukhazikika, HPMC imakonzeka kusewera gawo lofunika kwambiri popanga malo omwe adamangidwa mawa.
