Zinthu zomwe zimakhudza ntchito ya ntchentche phulusa

Pali zinthu zambiri zomwe zimakhudza ntchito ya ntchentche phulusa ndizovuta kwambiri. Zomwe zimawongolera zikuphatikizapo: mankhwala (makamaka gawo lagalasi); kapangidwe ka galasi; kuwonongeka kwa mankhwala ndi thupi la malo otsegulira mu galasi (kuphatikiza zomwe zimapangidwa ndi kugaya); madzi Ntchito ya sing'anga mankhwala anachita; kukula kwa tinthu tating'onoting'ono. Kuchulukirachulukira kwa njira zopangira phulusa la ntchentche, m'pamenenso phulusa la ntchentche limamera bwino, ndipo mtengo wa phulusa la ntchentche umakwera kwambiri. Koma kawirikawiri, ikhoza kugawidwa m'magulu awiri; imodzi ndi mankhwala, omwe makamaka amakhudza chiwerengero ndi mapangidwe a zinthu zomwe zimagwira nawo ntchito ndikulimbikitsa machitidwe a pozzolanic; chinacho ndi chakuthupi, chomwe chimakhudza kwambiri njira ya hydration ndi kuumitsa simenti Mapangidwe a miyala ya simenti yopangidwa pambuyo pake.

1. Zinthu za mankhwala

Popeza gawo la galasi la silika-aluminium ndiye gwero lalikulu la ntchito yakuwuluka phulusa , zinthu zomwe zimachepetsa kuchuluka kwa matupi agalasi, monga kutaya kwakukulu pakuyatsa ndi magawo ambiri a crystalline, sizothandiza pa ntchitoyi. Kuonjezera apo, popanga gawo la galasi, maudindo a zinthu zosiyana sali ofanana. Ma oxides ndi omwe amapezeka kwambiri m'thupikuwuluka phulusa , komanso ndi zigawo zikuluzikulu za mankhwala hydration. Komabe, pansi pa zaka zosiyanasiyana ndi kutentha, digiri ndi kufunikira kwa ma oxides omwe amatenga nawo gawo muzochita za hydration ndizosiyana. Mwachitsanzo, chitsulo chingachepetse kusungunuka kwa phulusa, zomwe zimathandiza kupanga magalasi a microbeads. Komabe, chifukwa chitsulo okusayidi ali ndi mphamvu osauka kwambiri kutenga nawo hydration reactions, ambiri amakhulupirira kuti chitsulo okusayidi wochulukirachulukira si abwino ntchito; pang'ono alkali zitsulo oxides akhoza kulimbikitsa hydration. Zimene ikuchitika, koma ntchito yogwira akaphatikiza, mkulu zili potaziyamu ndi sodium oxides mu ntchentche phulusa kulimbikitsa zimene alkaline akaphatikiza, potero kuwononga bata la konkire; sulfure trioxide pang'ono mu phulusa la ntchentche Zimapindulitsa pakupanga hydrated calcium silicate ndi mapangidwe a hydrated calcium sulfoaluminate (ettringite) yomwe imathandizira ku mphamvu yoyambirira, koma kuwonjezeka kwakukulu kwa ettringite kumayambitsa mavuto okhazikika, kotero Zomwe zili mu sulfure trioxide siziyenera kukhala 3%.

2. Zinthu zakuthupi

Zifukwa zazikulu zomwe zimakhudza ntchito ya ntchentche phulusa ndi tinthu morphology, microstructure ndi zinthu zina zakuthupi. Kwa mitundu yosiyanasiyana ya phulusa la ntchentche, zocheperako zomwe zimafunikira madzi amtundu wanthawi zonse, zimakweza ntchitoyo; kutsika kwa carbon, kumapangitsa kuti ntchitoyo ikhale yokwera; ang'onoang'ono fineness, ndi apamwamba ntchito; mwa mawu a tinthu morphology, galasi ozungulira mu ntchentche phulusa The kwambiri, ndi apamwamba ntchito ya ntchentche phulusa. Kuchokera ku microstructure khalidwe E, thekuwuluka phulusandi mawonekedwe afupiafupi a silicon-oksijeni tetrahedral ali ndi ntchito yayikulu.

Malo enieni a phulusa la ntchentche amatha kuwonetsa kapangidwe kake ndi kapangidwe ka phulusa la ntchentche pamlingo wina. Tinthu tating'onoting'ono ta phulusa la ntchentche timakhala ndi malo okulirapo; magalasi olemera a calcium ali ndi mawonekedwe owundana komanso malo ang'onoang'ono ofanana; pali magalasi ambiri amadzimadzi. Mabowo, lolingana enieni pamwamba m'dera lalikulu.
