Dziko lathu ndi "logwiritsa ntchito kwambiri" magalasi. Chifukwa cha chitukuko chachuma chomwe chikuchitika mwachangu, kugwiritsa ntchito magalasi kukuchulukirachulukira tsiku ndi tsiku, ndipo kutaya magalasi otayidwa pang'onopang'ono kwakhala nkhani yovuta. Gawo lalikulu la galasi ndi silica yogwira ntchito, kotero ikaphwanyidwa kukhala ufa, imatha kukhala ndi mphamvu ya pozzolanic ndipo ingagwiritsidwe ntchito ngati chosakaniza pokonzekera konkire. Izi sizingathetse vuto lotaya magalasi otayidwa okha, komanso zimalimbikitsa chitukuko cha zipangizo zomangira zobiriwira komanso zosawononga chilengedwe.Makina a HCMndi kampani yopanga mphero. Mphero yomwe timapanga ndi zipangizo zomwe zimagwiritsidwa ntchito popera ufa wagalasi. Lero ndikudziwitsani ntchito ya ufa wagalasi pa simenti.

Pofufuza mayeso a mphamvu yokakamiza ya konkriti yosakanikirana ndi ufa wagalasi ndi zotsatira za mayeso a simenti a microscopic, zitha kutsimikiziridwa kuti ngakhale CaO ya ufa wagalasi imatha kuchita ndi madzi, ndi yofooka kwambiri. Chifukwa chake, zitha kuganiziridwa kuti ufa wagalasi ulibe kuuma kwa hydraulic. Pamene kuchuluka kwa ufa wagalasi wosakaniza ndi 10%, mwachitsanzo, silica yogwira ntchito, alumina ndi calcium hydroxide mu ufa wagalasi zimachita kuti zipange calcium silicate yotsika-alkalinity. Silica yogwira ntchito imathanso kuchita ndi calcium silicate yotsika-alkalinity. Calcium silicate hydrate imachita kuti ipange calcium silicate hydrate yotsika-alkali. Pamene ikuchepetsa kuchuluka kwa calcium hydroxide, gawo la calcium silicate yosungunuka imapangidwa, zomwe zimapangitsa kuti slurry yolimba ikhale yolimba komanso kuti isalowerere; Zimakhudzana ndi mankhwala oyeretsera simenti calcium hydroxide (Ca(OH)2) kuti apange madzi. Calcium silicate yonyowa imachepetsa kuchuluka kwa Ca(OH)2 mu konkire, imawonjezera kuchuluka kwa calcium silicate yonyowa, ndikuwonjezera mphamvu ya konkire. Pamene kuchuluka kwa ufa wa galasi kufika pa 20%, chifukwa kuchuluka kwa simenti kumachepa, ma hydrate opangidwa ndi madzi a simenti amachepanso, koma ufa wa galasi umayanjana ndi madzi a simenti kuti apange calcium silicate yonyowa pang'ono. Pamene kuchuluka kwa ufa wa galasi kufika pa 20%, mphamvu imakhala yofanana ndi konkire yoyeretsera. Pamene kuchuluka kwa ufa wa galasi kukupitirira kuwonjezeka ndipo kuchuluka kwa simenti kumachepa pang'onopang'ono, kuchuluka kwa zinthu zoyeretsera kumakhala kochepa, ndipo ufa wa galasi umayanjana ndi madzi a simenti. Madzi ochulukirapo sakwanira kubweza kuchepa kwa zinthu zoyeretsera chifukwa cha kuchepa kwa simenti. Chifukwa chake, mphamvu ikuchepa. Zimapezekanso kuti pamene kuchuluka kwa ufa wa galasi kuli kochuluka, ming'alu idzawonekera.

Izi zili choncho chifukwa ngakhale kuchuluka kwa simenti kumachepa, kufunikira kwa silica yogwira ntchito yomwe imagwira ntchito mu hydration reaction kumachepanso. Silica yogwira ntchito yotsalayo imagwirizana ndi zinthu za alkaline mu ufa wagalasi, zomwe zimapangitsa kuti konkire ikule mkati. Phala lolimba la simenti lidzaswekanso ndikupanga ming'alu yayikulu, ndipo mphamvu ya simenti idzachepanso.

Mphamvu ya ufa wa galasi pa simenti:

(1) Mphamvu yokakamiza ya masiku 28 ya konkriti yokonzedwa ndi ufa wagalasi wowonekera wopanda utoto ndi ufa wobiriwira wagalasi wosakaniza ndi 10% ndi 15% ya simenti m'malo mwa simenti ndi yokwera kuposa ya konkriti yoyeserera; pamene mlingo uli 20%, mphamvu imakhala yofanana ndi ya konkriti yoyesera. Poyerekeza ndi konkriti; pamene mlingo uli 30% kapena kupitirira apo, mphamvu yokakamiza ya konkriti imachepa kwambiri.

(2) Ngati palibe ufa wagalasi womwe wawonjezeredwa, calcium hydroxide imasungunuka bwino ndipo imakhala yayikulu kukula. Pamene ufa wagalasi ukuwonjezeka, kuchuluka kwa calcium hydroxide kumachepa pang'onopang'ono ndipo makristalo amawonjezeka kwambiri.

(3) Kuyika ufa wagalasi wamitundu yosiyanasiyana sikukhudza kwambiri mphamvu ya konkriti.

(4) Ufa wagalasi umagwiritsidwa ntchito popangira konkire ndipo umakhudza kwambiri chilengedwe.

The role and economic benefits of glass powder on cement: Glass powder replaces cement, which can save 19,300 kW. , NOx15.1 t. If 20% of the 3.2 million tons of waste glass produced every year in our country is used to prepare concrete, there will be great ecological and economic benefits. The waste glass grinding machine produced by HCM Machinery is equipment for producing glass powder. It can process 80-600 waste glass powder to meet the processing needs of glass powder cement substrate. If you have relevant needs, please give us a call for details：hcmkt@hcmilling.com
