Izinkinga eziningana ekwakhiweni kokhonkolo owenziwe ngegwebu

Ukhonkolo we-Foam ijeli elixubile lezinto ezihlukahlukene kanye nezixube. Izinto ezihlukene zezinto zokusetshenziswa, izilinganiso ezahlukene zokuxuba izinto, izakhiwo ezahlukene admixtures, izilinganiso ezahlukene zokuhlanganisa amanzi noketshezi, amazinga okusebenza ahlukene emishini yokwakha kanye nabasebenzi bokwakha, izindawo ezahlukene zokwakha kanye nezimo zokunakekelwa konke kuzoletha ikhwalithi yemikhiqizo yekhonkrithi yegwebu. Ithonya elikhulu iphrojekthi yokwakha yobuchwepheshe bokulawula okuguquguqukayo okuningi. Ukungenelela kwayo yonke ipharamitha eguquguqukayo kuzokwenza umehluko omkhulu kukhwalithi yekhonkrithi yegwebu. Ngakho-ke, isilinganiso sokuxuba ekwakhiweni sibaluleke kakhulu. Indlela yokuxazulula izinkinga ezihlobene ezithinta ikhwalithi yomkhiqizo ekwakhiweni kwekhonkrithi yegwebu elifakwe endaweni okugxilwe kuyo kulesi sihloko..

1. The influence of material mixing ratio on project quality

As we all know, the mixing ratio of materials in the construction of foam concrete is the main factor affecting the quality of the project. Ukusebenza kokhonkolo we-foam kuthinteka yizici eziningi. There are many problems in quality control, and intelligent and automated construction machinery is still under further development. The mixing ratio, construction method, site management and other aspects of the cast-in-situ project of foam concrete are still in the initial stage of development. Tests have shown that the strength of the product can be increased within the optimum content of fly ash, and its strength will decrease after the optimum content is exceeded;

Kungokufanayo nangosimende. Ngemuva kokuthi umthamo omkhulu weqiwe, its strength decreases as the amount of cement increases. This warns us that the optimal amount of materials must be controlled reasonably, ikakhulukazi ukungezwa kwezakhi zokulandelela ezifana ne-silica fume kufanele kucace kakhudlwana.

Ukwengeza kakhulu noma ngokungalingani kuzodala imfucuza. Ngakho-ke, the use of a mechatronics uniform speed measurement system for control is an ideal solution.

2 The influence and control of admixtures on the quality of foam concrete

Kunezingxube eziningi zokhonkolo wegwebu, ikakhulukazi ama-agent akhipha amagwebu usimende, ama-accelerator, kanye nama-ejenti okunciphisa amanzi. The matching parameters should be accurate. Njenge-ejenti yokukhipha amagwebu usimende, the control of the initial water-liquid mixing ratio and the control of the foaming rate will have a great impact on the quality of foamed concrete. The mixing ratio control of cement foaming agent and other raw materials is not accurate enough, which makes the construction quality not stable enough.

Uhlelo lokulawula i-ejenti enegwebu olusetshenziswayo njengamanje lungahlukaniswa ngezigaba ezintathu, okungukuthi ukulawula iphampu yegiya, hose pump control and straw cross-section ratio control. Ngokungqubuzanayo, the gear pump control class is more accurate. Nokho, most of the gear pumps currently in use are substitutes, engasetshenziswa ezinhlelweni ezisebenza nge-hydraulic, kodwa uhlelo lokukala ama-ejenti ogwebu ludinga ukuthuthukiswa, ngoba indawo yokungena esikhundleni sephampu yegiya yenziwe nge-aluminium alloy, and the internal gears are quenched by carbon steel. The hardness of the two parts is very different. Endabeni yokungagcobi kahle, i-aluminium alloy ye-valve plate yangaphakathi kulula kakhulu ukugqoka futhi ibangele ukuvuza kwangaphakathi. Ngaphezu kwalokho, the internal carbon steel gear has defects such as easy corrosion, fast wear, and large internal leakage, which directly affect the measurement accuracy. The reason is that the foaming agent is a neutral substance in theory, but in fact many foaming agents are weakly alkaline or weakly acidic, which will corrode the carbon steel gears in the gear pump to a certain extent and accelerate the wear; Ngaphezu kwalokho, The foaming agent itself has a certain viscosity. If it is not cleaned or cleaned after work, it is easy to build up and block the distribution channel in the gear pump, which will increase the internal resistance of the gear pump, accelerate the wear, and increase the measurement error. Inani elikhulu, the water-liquid mixing ratio of the foaming agent will be affected, izinga legwebu ngeke lizinze, and the product quality of the foamed concrete will be directly affected. This is also an urgent problem that needs to be resolved.

I-Cie-China.org ingumhlinzeki oholayo wezithasiselo zikakhonkolo wegwebu ohlinzeka nge-ejenti yokugwedla ukhonkolo, superplasticizer,isithuthukisi samandla kakhonkolo wegwebu kukhonkolo ongasindi, Amabhulokhi e-CLC. Uma ufunai-ejenti ekhihlizayo, sicela ukhululekeXhumana nathi.
