Gypsum retarder imathandizira kusinthika kwa zomangamanga komanso Chitukuko chokhazikika

Gypsum retarder ndi chowonjezera chofunikira chomanga, chopangidwa kuti chiwonjezere nthawi yokhazikika ya zida za gypsum, potero kupititsa patsogolo kugwira ntchito kwa zomangamanga. Mankhwalawa amagwiritsidwa ntchito kwambiri pantchito yomanga, makamaka pama projekiti omwe amafunikira nthawi yayitali yomanga, ndipo amagwira ntchito yofunika kwambiri. Chifukwa cha nthawi yaying'ono yokhazikika ya gypsum yachikhalidwe, imachepetsa ntchito yomanga yayikulu komanso yovuta, ndipo pambuyo powonjezerapo retarder, ogwira ntchito amatha kupanga zomanga ndikusintha mosavuta, kuwonetsetsa kuti ntchito yomangayo ndi yabwino komanso yothandiza.

Zigawo zazikulu za gypsum retarder zingaphatikizepo zinthu zosiyanasiyana organic ndi inorganic, monga sodium citrate, tartaric acid ndi zina zotero. Pochita zinthu ndi zida zosungunuka mu gypsum, zinthuzi zimachedwetsa kuchuluka kwa hydration reaction ya gypsum, motero zimachedwetsa nthawi yoyamba komanso yomaliza ya coagulation. Kuchedwa kumeneku sikumakhudza mphamvu yomaliza ya pulasitala, kuonetsetsa kukhazikika ndi kukhazikika kwa mankhwala omalizidwa.

M'zaka zaposachedwa, ndikusintha kwaukadaulo wa zomangamanga ndi miyezo yomanga, kufunikira kwa gypsum retarder kukukulirakulira. Ma gypsum retardants atsopano okonda zachilengedwe amakondedwa pang'onopang'ono ndi msika, ndipo amagwiritsa ntchito mitundu yobiriwira komanso yokhazikika kuti achepetse kuwononga chilengedwe. Opanga akuyang'ana kwambiri za chitukuko cha anthu oletsa kuwononga zachilengedwe komanso otetezeka kuti akwaniritse zosowa zachitukuko chamakampani amakono omanga.

Kugwiritsa ntchito gypsum retarder ndikokulirapo kwambiri, kuphatikiza pulasitala pakhoma, denga, kukongoletsa zokongoletsera ndi zina zotero. Zimatsimikizira kusinthasintha kwa ntchito yomanga popanda kukhudza katundu wakuthupi ndi kukongola kwa mankhwala omalizidwa. Izi zimapangitsa mankhwala kukhala chimodzi mwazinthu zofunika kwambiri pakumanga kwamakono.

Nthawi zambiri, gypsum retarder ngati chowonjezera chamankhwala kuti apititse patsogolo ntchito yomanga, kulimbikitsa kupita patsogolo kwaukadaulo wamakampani omanga, pomwe kutsata njira yachitukuko chokhazikika, kuthekera kwa msika wamtsogolo sikunganyalanyazidwe.
