Lagu daro la taaban karo oo khafiif ah | Wakiilada Xumbaynta Waxqabadka Sare ee Shabka Gacanta
Shubka xumbo waa jel isku dhafan oo ah walxo kala duwan iyo isku-dar ah. Qalabka kala duwan ee alaabta ceeriin, Saamiyada isku dhafka kala duwan ee alaabta, sifooyinka kala duwan ee admixtures, saamiga isku dhafka dareeraha biyaha ee kala duwan, heerarka kala duwan ee hawlgalka mishiinada dhismaha iyo shaqaalaha dhismaha, deegaan dhismo oo kala duwan iyo xaaladaha dayactirka ayaa dhamaantood keeni doona tayada alaabta la taaban karo ee xumbo. Saamaynta weyni waa mashruuc dhisme oo ah tignoolajiyada xakamaynta kala duwan ee kala duwan. Faragelinta halbeeg kasta oo doorsoome ah ayaa wax weyn ka beddeli doonta tayada shubka xumbo. Sidaa darteed, saamiga isku dhafka ah ee dhismaha ayaa aad muhiim u ah. Sida loo xalliyo dhibaatooyinka la xidhiidha ee saameeya tayada alaabta dhismaha ee shubka xumbo-ku-meel-gaadhka ah waa diiradda qodobkan.
1. The influence of material mixing ratio on project quality
Sidaan wada ognahay, the mixing ratio of materials in the construction of foam concrete is the main factor affecting the quality of the project. Waxqabadka shubanka xumbo waxaa saameeya arrimo badan. 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;
Sibidhkana waa sidaas oo kale. Ka dib markii qiyaasta ugu wanaagsan la dhaafo, its strength decreases as the amount of cement increases. This warns us that the optimal amount of materials must be controlled reasonably, gaar ahaan ku darida walxaha raadraaca sida qiiqa silica waa inay ahaataa mid sax ah.
Ku darida badan ama aan sinnayn waxay keenaysaa qashin. Sidaa darteed, 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
Waxaa jira waxyaabo badan oo isku dhafan oo loogu talagalay shubka xumbo, inta badan walaxyada sibidhka, dardargeliyayaasha, iyo wakiilada biyaha dhimaya. The matching parameters should be accurate. Sida wakiilka xumboynta sibidhka, 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.
Nidaamka xakamaynta xumbo-samaynta ee hadda la isticmaalo waxa loo qaybin karaa saddex qaybood, kuwaas oo ah xakamaynta bamka gear-ga, hose pump control and straw cross-section ratio control. Taas bedelkeeda, the gear pump control class is more accurate. Si kastaba ha ahaatee, most of the gear pumps currently in use are substitutes, kaas oo loo isticmaali karo hababka hawo-mareenada, laakiin habka cabbiraadda wakiilka xumboynta ayaa u baahan in la hagaajiyo, sababtoo ah guriga bamka gear-ga beddelka ah wuxuu ka samaysan yahay aluminium aluminium ah, and the internal gears are quenched by carbon steel. The hardness of the two parts is very different. Marka la eego saliidda liidata, daawaha aluminium ee saxanka waalka gudaha waa mid aad u fudud in la xidho oo keena dheecaan gudaha ah. Waxaa intaa dheer, qalabka birta kaarboon ee gudaha ayaa leh cillado sida daxal fudud, xirashada degdega ah, iyo dareere weyn oo gudaha ah, kaas oo si toos ah u saameeya saxnaanta cabbirka. Sababta ayaa ah in wakiilka xumbayntu uu yahay walax dhexdhexaad ah aragtida, laakiin dhab ahaantii qaar badan oo ka mid ah wakiilada xumbo waa alkaline daciif ah ama daciif ah acidic, kaas oo daxaleynaya gears-ka birta kaarboon ee ku jira bamka gear-ka ilaa xad iyo dedejin doona xidhashada; in addition, Wakiilka xumbaynta lafteedu waxay leedahay viscosity gaar ah. Haddii aan la nadiifin ama aan la nadiifin shaqada ka dib, Way fududahay in la dhiso oo la xannibo kanaalka qaybinta ee bamka qalabka, taas oo kordhin doonta caabbinta gudaha ee bamka gear-ka, dedejiso xidhashada, and increase the measurement error. Way weyn tahay qiimaha, saamiga isku dhafka dareeraha biyaha ee wakiilka xumbada ayaa saameyn doonta, tayada xumbo ma noqon doonto mid deggan, and the product quality of the foamed concrete will be directly affected. This is also an urgent problem that needs to be resolved.
