Dziko lathu ndi "ogula zinthu zambiri" zamagalasi.Ndi chitukuko chofulumira chachuma, kumwa magalasi kukukulirakulira tsiku ndi tsiku, ndipo kutaya magalasi otayira pang'onopang'ono kwakhala vuto lalikulu.Chigawo chachikulu cha galasi ndi silika yogwira ntchito, choncho itatha kukhala ufa, imatha kukhala ndi ntchito ya pozzolanic ndipo ingagwiritsidwe ntchito ngati chosakaniza pokonzekera konkire.Izi sizingathetse vuto la kutaya galasi lotayirira, komanso kulimbikitsa chitukuko cha zipangizo zomangira zobiriwira komanso zachilengedwe.Makina a HCMndi wopanga mphero.Mphero yomwe timapanga ndi zida zomwe zimagwiritsidwa ntchito pogaya ufa wagalasi.Lero ndikufotokozerani ntchito ya ufa wagalasi pa simenti.
Pofufuza kuyesa kwa mphamvu ya konkire yosakanikirana ndi ufa wagalasi ndi zotsatira zofufuza zazing'ono za phala la simenti, zikhoza kuganiziridwa kuti ngakhale CaO ya ufa wa galasi ikhoza kuchitapo kanthu ndi madzi, ndi yofooka kwambiri.Choncho, zikhoza kuganiziridwa kuti ufa wa galasi ulibe kuuma kwa hydraulic.Pamene kusanganikirana kuchuluka kwa galasi ufa ndi 10% Mwachitsanzo, yogwira silika, aluminiyamu ndi kashiamu hydroxide mu galasi ufa amachita kupanga otsika alkalinity hydrated kashiamu silicate.Silika yogwira ntchito imathanso kuchitapo kanthu ndi high-alkalinity hydrated calcium silicate.Calcium silicate hydrate imachita kupanga otsika alkali calcium silicate hydrate.Pamene kuchepetsa calcium hydroxide okhutira, gawo la hydrated kashiamu silicate amapangidwa, amene bwino kachulukidwe ndi impermeability wa slurry wowuma;imakhudzidwa ndi simenti ya hydration mankhwala calcium hydroxide (Ca (OH) 2) kupanga madzi Hydrated calcium silicate imachepetsa zomwe zili mu Ca (OH) 2 mu konkire, imawonjezera zomwe zili mu hydrated calcium silicate, ndi kupititsa patsogolo mphamvu ya konkire. Magalasi a ufa wa galasi amafika 20%, chifukwa simenti imachepa, ma hydrates opangidwa ndi simenti hydration amachepetsanso, koma ufa wa galasi umakhudzidwa ndi simenti hydrates kupanga pang'ono hydrated calcium silicate.Pamene kuchuluka kwa galasi ufa kufika 20%, mphamvu akadali ofanana ndi benchmark konkriti.Pamene kuchuluka kwa ufa wa galasi kumapitirirabe kukula ndipo simenti imachepa pang'onopang'ono, kuchuluka kwa zinthu za hydration kumakhala kochepa, ndipo galasi la ufa limakhudzidwa ndi simenti hydrates Kuwonjezeka kwa hydrate sikukwanira kulipira kuchepa kwa mankhwala a hydration chifukwa cha kuchepa kwa simenti.Chifukwa chake, mphamvu ikucheperachepera.Zimapezekanso kuti pamene kuchuluka kwa ufa wa galasi ndi wochuluka, ming'alu idzawoneka.
Izi ndichifukwa choti ngakhale kuchuluka kwa simenti kumachepetsedwa, kufunikira kwa silica yogwira nawo gawo mu hydration reaction kumachepetsedwanso.Silika yotsalira yogwira imachita ndi zinthu zamchere mu galasi ufa, kuchititsa kukula kwamkati kwa konkire.Phala la simenti lolimba lidzaswekanso ndi kupanga ming'alu yayikulu, ndipo mphamvu ya konkire idzachepanso.
Zotsatira za ufa wagalasi pa simenti:
(1) The 28-day compressive mphamvu konkriti wokonzedwa ndi colorless manla galasi ufa ndi wobiriwira galasi ufa wothira 10% ndi 15% ya simenti m'malo simenti ndi apamwamba kuposa a benchmark konkire;pamene mlingo ndi 20%, mphamvu ndi yofanana ndi konkire ya benchmark.Zofanana ndi konkriti;pamene mlingo ndi 30% ndi pamwamba, compressive mphamvu konkire amachepetsa kwambiri.
(2) Popanda galasi ufa wothira, calcium hydroxide imawala bwino ndipo imakhala yokulirapo.Pamene kuchuluka kwa ufa wa galasi kumawonjezeka, zomwe zili mu calcium hydroxide zimachepa pang'onopang'ono ndipo crystallization imakhala yoipitsitsa.
(3) Kuwonjezera ufa wagalasi wamitundu yosiyanasiyana sikumakhudza kwambiri mphamvu ya konkire.
(4) ufa wagalasi umagwiritsidwa ntchito pokonza konkire ndipo umakhala ndi zotsatira zabwino pazachilengedwe.
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
