Ndi kuphatikiza kotani komwe kungathandizire kukhazikika kwa konkriti?(HPMC)

Hydroxypropylmethylcellulose (HPMC) ndi gulu losunthika lomwe limagwiritsidwa ntchito popanga zomangamanga, kuphatikiza zopangira konkriti.Ngakhale sizingawongolere kulimba kwa konkriti, zimagwira ntchito yofunika kwambiri pakuwongolera zinthu zosiyanasiyana za konkriti.

1. Chiyambi cha hydroxypropyl methylcellulose:

Hydroxypropyl methylcellulose (HPMC) ndi etha yosinthidwa ya cellulose yochokera ku ma polima achilengedwe.Chifukwa cha mawonekedwe ake apadera, amagwiritsidwa ntchito kwambiri ngati chowonjezera pazomangira.Mu konkire, HPMC imagwiritsidwa ntchito ngati chosungira madzi, thickener, ndi binder.Kapangidwe kake ka mankhwala kumathandizira kupanga filimu yoteteza kuzungulira tinthu ta simenti, zomwe zimakhudza ma rheological ndi makina osakanikirana a konkire.

2. Udindo wa HPMC pakukhazikika kwa konkriti:

Kusungidwa kwa madzi ndi ntchito:

HPMC imagwira ntchito ngati chosungira madzi, kuteteza kutaya madzi ochulukirapo kumayambiriro kwa kuchiritsa konkire.
Kusungika bwino kwa madzi kumeneku kumathandizira kuti konkriti ikhale yogwira ntchito bwino, zomwe zimapangitsa kuti konkriti ikhale yabwino komanso kuphatikizika.

Wonjezerani adhesion:

Kapangidwe ka filimu ka HPMC kumathandizira kumamatira pakati pa tinthu tating'ono ta simenti, zomwe zimapangitsa kuti pakhale konkriti yolumikizana komanso yolimba.

Chepetsani kulekana ndi kutuluka magazi:

HPMC imathandiza kuchepetsa chiopsezo cha tsankho ndi kutaya magazi mu zosakaniza za konkire, zomwe zimapangitsa kuti pakhale yunifolomu, yomveka bwino.

Nthawi yokhazikitsira bwino:

Kugwiritsiridwa ntchito kwa HPMC kungakhudze nthawi yoyika konkire, potero kumapereka mgwirizano pakati pa kugwira ntchito ndi kupititsa patsogolo mphamvu.

Mphamvu pamakina:

Ngakhale HPMC palokha mwina kumapangitsanso kulimba kwa konkire, zotsatira zake pa workability ndi adhesion zingakhudze mwachindunji katundu makina konkire, kuthandiza kulenga amphamvu ndi cholimba nyumba.

3. Zolemba ndi machitidwe abwino:

Kuwongolera mlingo:

Mlingo woyenera wa HPMC ndi wofunikira.Kupitilira muyeso kumatha kubweretsa zovuta, pomwe kutsitsa sikungapereke kusintha kofunikira.

kugwilizana:

Kugwirizana ndi admixtures ena konkire ndi zipangizo ayenera kuganiziridwa kupewa chilichonse chokhwima zochita kuti kusokoneza katundu wa konkire osakaniza.

Njira yothetsera:

Ngakhale HPMC imathandiza kusunga madzi, njira zochiritsira zoyenera ziyenera kugwiritsidwa ntchito kuonetsetsa kuti konkire imakhala yolimba.

Ngakhale HPMC si wothandizira mwachindunji kuti bwino durability wa konkire, ntchito yake zosakaniza konkire akhoza kusintha workability, adhesion, ndi katundu zina, potero kuwongolera kulimba wonse wa nyumba konkire.HPMC iyenera kuganiziridwa ngati gawo la njira yophatikizira yopangira konkriti komanso njira zomanga kuti zikwaniritse zokhazikika komanso zolimba.
