Kutentha kochepa m'nyengo yozizira kwalepheretsa ntchito ya maphwando omanga.Pakumanga konkire, njira zogwirira ntchito ziyenera kuchitidwa kuti zisawonongeke chifukwa cha kuzizira panthawi yowumitsa konkire.Miyezo yachikhalidwe ya antifreeze sikuti imangogwiritsa ntchito mphamvu zambiri, komanso imafunikira antchito owonjezera ndi zida, zomwe zimawonjezera zovuta zomanga ndi mtengo.
Ndiye kodi konkire iyenera kumangidwa bwanji m'nyengo yozizira?Ndi njira ziti zomwe zingachepetse vuto la kumanga konkriti?
M'nyengo yozizira yomanga konkire, zosakaniza zimagwiritsidwa ntchito kuti ziwonjezere mphamvu.Ndipotu, zakhala mgwirizano mumakampani kuti agwiritse ntchito zosakaniza kuti athetse mavuto omanga konkire m'nyengo yozizira.Kwa mayunitsi omanga, zowonjezera zowonjezera zowonjezera zimapatsidwa patsogolo panthawi yomanga konkire m'nyengo yozizira.Zowonjezera za konkire zoyambirira zimatha kufulumizitsa kuthamanga kwa simenti, kupangitsa kuti ikhale yolimba komanso yamphamvu mwachangu.Mphamvu yovuta imatha kufika kutentha kwa mkati kusanatsike pansi pa 0 ° C, kuchepetsa Kuvuta ndi zovuta za zomangamanga za konkire m'madera otsika kutentha kumachepetsanso ndalama zomanga.
Kuphatikiza pa zida zoyambira mphamvu, antifreeze ingathandizenso pakumanga konkriti.Konkire antifreeze imatha kuchepetsa kwambiri kuzizira kwa gawo lamadzimadzi mu konkriti, kuletsa madzi kuzizira, kufulumizitsa kuyatsa koyambirira kwa simenti, ndikuchepetsa kuthamanga kwa ayezi.Kuyenera kukumbutsidwa kuti ntchito kutentha kwa antifreeze ndi kutentha komwe kumalola konkriti yomanga, koma ziyenera kumveka pokhudzana ndi mphamvu yotsutsa-kuundana ya konkire, ndiko kuti, kutentha kozungulira kumatsika kukugwiritsa ntchito kutentha kwa admixture. , konkire iyenera kufika ku mphamvu yotsutsa-kuzizira.Mwanjira iyi konkire imakhala yotetezeka.
Admixtures amagwira ntchito yofunika kwambiri poonetsetsa kuti konkire imamangidwa m'nyengo yozizira.Pokhapokha podziwa mfundo zogwiritsira ntchito zosakaniza mu konkire yomanga yozizira ndi kupanga zomangamanga zomwe zingatheke kuti konkire ikhale yabwino.
