Setting-Accelerator-Calcium Formate

Calcium formate imatha kukhala ngati chowonjezera pa konkriti. Umu ndi momwe zimagwirira ntchito:

Kukhazikitsa Mathamangitsidwe Mechanism:

1. Njira ya Hydration: calcium formate ikawonjezeredwa ku zosakaniza za konkire, imasungunuka m'madzi ndikutulutsa ayoni a calcium (Ca ^ 2+) ndi ma ion a formate (HCOO^-).
2. Kulimbikitsa Mapangidwe a CSH: Ma ion a calcium (Ca ^ 2 +) otulutsidwa kuchokera ku calcium formate amachitira ndi ma silicates mu simenti, kufulumizitsa mapangidwe a gel a calcium silicate hydrate (CSH). Gelisi ya CSH iyi ndiye chomangira konkriti, chomwe chimakhala ndi mphamvu komanso kulimba kwake.
3. Nthawi Yoyikira Mwachangu: Kupanga kofulumira kwa gel osakaniza a CSH kumabweretsa nthawi yokhazikika yosakaniza konkriti. Izi zimalola kumalizidwa mwachangu komanso kuchotsedwa koyambirira kwa formwork, kufulumizitsa ntchito yonse yomanga.

Ubwino Wogwiritsa Ntchito Calcium Formate Monga Accelerator Yokhazikitsira:

1. Kupititsa patsogolo Mphamvu Zoyambirira: Mphamvu yoyambirira ya konkire imakulitsidwa chifukwa cha kuthamangitsidwa kwa hydration komwe kumayendetsedwa ndi calcium formate. Izi zitha kukhala zothandiza makamaka nyengo yozizira pomwe nthawi yocheperako imawonedwa.
2. Kuchepetsa Nthawi Yomanga: Mwa kufulumizitsa nthawi yoyika konkire, mawonekedwe a calcium amathandizira kuchepetsa nthawi yomanga ndikulola kuti ntchitoyo ithe mwachangu.
3. Kupititsa patsogolo Kugwira Ntchito: Calcium Formate imathanso kupititsa patsogolo kugwira ntchito kwa konkire, kupangitsa kuti ikhale yosavuta kuyigwira ndi kuyiyika, makamaka pamene kuyikako kumafunikira.

Ntchito mu Konkire:

• Calcium formate nthawi zambiri imawonjezedwa ku zosakaniza za konkire pa mlingo woyambira 0.1% mpaka 2% pa kulemera kwa simenti, kutengera nthawi yomwe mukufuna komanso zofunikira pakuchita.
• Nthawi zambiri amagwiritsidwa ntchito popanga konkriti yokhazikika, kugwiritsa ntchito shotcrete, ndi ntchito zomanga pomwe kukhazikika ndikofunikira.

Zoganizira:

• Ngakhale kuti calcium formate imatha kufulumizitsa nthawi yoyika konkriti, ndikofunikira kuganizira mozama kuchuluka kwa mlingo ndi kugwirizana ndi zosakaniza zina kuti mupewe zotsatira zoyipa za konkriti.
• Njira zowongolera upangiri ziyenera kukhazikitsidwa kuti konkriti yothamanga ikhalebe ndi mphamvu, kulimba, komanso magwiridwe antchito.

Calcium formate imagwira ntchito ngati chiwongolero chothandizira mu konkriti, kulimbikitsa kuthamanga kwamadzi komanso kukula kwamphamvu koyambirira. Kugwiritsiridwa ntchito kwake kungathandize kufulumizitsa ndondomeko yomanga ndi kupititsa patsogolo ntchito, makamaka nyengo yozizira kapena ntchito zomwe zimakhala zovuta nthawi. Komabe, mulingo woyenera komanso zofananira ndizofunikira kuti mukwaniritse zomwe mukufuna mukamagwiritsa ntchito calcium formate ngati chowonjezera.
