Quyma ko'pikli betonni qurishda bir nechta muammolar

Ko'pikli beton - bu turli xil materiallar va aralashmalarning aralash jeli. Xom ashyoning turli xil materiallari, different mixing ratios of materials, aralashmalarning turli xossalari, different water-liquid mixing ratios, qurilish texnikasi va qurilish xodimlarining turli ish darajalari, different construction environments and maintenance conditions will all bring about the quality of foam concrete products. Katta ta'sir ko'p o'zgaruvchan boshqaruv texnologiyasining qurilish loyihasidir. Har bir o'zgaruvchan parametrning aralashuvi ko'pikli betonning sifatiga katta o'zgarishlar kiritadi. Shuning uchun, qurilishda aralashtirish nisbati juda muhimdir. Quyma ko'pikli betonni qurishda mahsulot sifatiga ta'sir qiluvchi muammolarni qanday hal qilish - ushbu maqolaning asosiy mavzusi..

1. The influence of material mixing ratio on project quality

Hammamiz bilganimizdek, the mixing ratio of materials in the construction of foam concrete is the main factor affecting the quality of the project. Ko'pikli betonning ishlashi ko'plab omillarga ta'sir qiladi. 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;

Xuddi shu narsa tsement uchun ham amal qiladi. Optimal dozadan oshib ketgandan keyin, its strength decreases as the amount of cement increases. This warns us that the optimal amount of materials must be controlled reasonably, ayniqsa, silika dumanı kabi iz elementlarning qo'shilishi aniqroq bo'lishi kerak.

Juda ko'p yoki notekis qo'shish chiqindilarga olib keladi. Shuning uchun, 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

Ko'pikli beton uchun ko'plab qo'shimchalar mavjud, asosan tsement ko'pikli moddalar, tezlatgichlar, va suvni kamaytiradigan moddalar. The matching parameters should be accurate. Tsement ko'pikli agenti kabi, 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.

Hozirgi vaqtda ishlatiladigan ko'pikli agentni boshqarish tizimini uchta toifaga bo'lish mumkin, ya'ni tishli nasosni boshqarish, hose pump control and straw cross-section ratio control. Farqli o'laroq, the gear pump control class is more accurate. Biroq, most of the gear pumps currently in use are substitutes, gidravlika tizimlarida foydalanish mumkin, lekin ko'pikli agentni o'lchash tizimini takomillashtirish kerak, chunki o'rinbosar tishli nasos korpusi alyuminiy qotishmasidan qilingan, and the internal gears are quenched by carbon steel. The hardness of the two parts is very different. Kambag'al moylash holatida, ichki valf plastinkasining alyuminiy qotishmasi juda oson kiyinadi va ichki qochqinning paydo bo'lishiga olib keladi. Bundan tashqari, ichki karbonli po'lat tishli oson korroziya kabi nuqsonlarga ega, tez kiyinish, va katta ichki oqish, o'lchov aniqligiga bevosita ta'sir qiladi. Buning sababi shundaki, ko'pikli vosita nazariy jihatdan neytral moddadir, lekin aslida ko'p ko'pikli moddalar zaif gidroksidi yoki zaif kislotali, tishli nasosdagi uglerodli po'lat viteslarni ma'lum darajada korroziyaga olib keladi va eskirishni tezlashtiradi; bunga qo'chimcha, Ko'pikli vositaning o'zi ma'lum bir viskoziteye ega. Ishdan keyin tozalanmasa yoki tozalanmasa, tishli nasosdagi tarqatish kanalini qurish va blokirovka qilish oson, bu tishli nasosning ichki qarshiligini oshiradi, eskirishni tezlashtiring, and increase the measurement error. Qiymat qanchalik katta, ko'pikli vositaning suv-suyuqlik aralashtirish nisbati ta'sir qiladi, ko'piklanish sifati barqaror bo'lmaydi, and the product quality of the foamed concrete will be directly affected. This is also an urgent problem that needs to be resolved.
