Gulu la mankhwala admixtures kwa matope

Zosakaniza za Chemical zamatope ndi konkriti zimakhala ndi zofanana komanso zosiyana. Izi makamaka chifukwa cha ntchito zosiyanasiyana za matope ndi konkriti. Konkire imagwiritsidwa ntchito makamaka ngati chomangira, pomwe matope nthawi zambiri amakhala omaliza komanso omangirira. Zosakaniza zamafuta amatope zitha kugawidwa molingana ndi kapangidwe kake ndi ntchito yayikulu.

Kugawikana ndi mankhwala

(1) Inorganic mchere matope zina: monga oyambirira mphamvu wothandizila, antifreeze wothandizira, accelerator, wothandizila kukulitsa, coloring wothandizira, madzi wothandizila, etc.;
(2) Ma polima surfactants: Mtundu uwu wa admixture makamaka surfactants, monga plasticizers/madzi reducers, shrinkage reducers, defoamers, air-entraining wothandizira, emulsifiers, etc.;
(3) ma polima utomoni: monga polima emulsions, redispersible polima ufa, mapadi ethers, madzi sungunuka zipangizo polima, etc.;

Zosankhidwa ndi ntchito yaikulu

(1) Zosakaniza kuti zipititse patsogolo ntchito (rheological properties) zamatope atsopano, kuphatikizapo plasticizers (ochepetsera madzi), othandizira mpweya, osungira madzi, ndi tackifiers (owongolera ma viscosity);
(2) Zosakaniza zosinthira nthawi yokhazikika komanso kuuma kwa matope, kuphatikiza obwezeretsa, obwezeretsanso kwambiri, ma accelerator, othandizira mphamvu zoyambira, ndi zina zotero;
(3) Admixtures kusintha durability wa matope, mpweya-entraining wothandizila, kuteteza madzi, dzimbiri inhibitors, fungicides, alkali-aggregate reaction inhibitors;
(4) Zosakaniza, zowonjezera zowonjezera ndi zochepetsera shrinkage kuti apititse patsogolo kukhazikika kwa matope;
(5) Admixtures kusintha makina zimatha matope, polima emulsion, redispersible polima ufa, mapadi efa, etc.;
(6) Admixtures, colorants, beautifiers pamwamba, ndi zowunikira kuti apititse patsogolo kukongoletsa kwa matope;
(7) Admixtures pomanga pamikhalidwe yapadera, antifreeze, kudzikonda leveling matope admixtures, etc.;
(8) Zina, monga fungicides, fibers, etc.;

Kusiyanitsa kofunikira pakati pa zida zamatope ndi zida za konkriti ndikuti matope amagwiritsidwa ntchito ngati matope ndi zomangira, ndipo nthawi zambiri amakhala wosanjikiza wocheperako akagwiritsidwa ntchito, pomwe konkriti imagwiritsidwa ntchito ngati zinthu zomangika, komanso kuchuluka kwake ndikwambiri. Choncho, zofunika workability wa malonda konkire zomangamanga makamaka bata, fluidity ndi fluidity posungira mphamvu. Zofunikira zazikulu zogwiritsira ntchito matope ndi kusunga madzi abwino, kugwirizana ndi thixotropy.
