Ntog huab cua voids Txo cov bugholes los ntawm kev siv: du, impermeable formwork; lub tsho thinnest ua tau ntawm tus neeg tso tawm tsim nyog; txwv nqa thicknesses; high-frequency vibrators; thiab cov txheej txheem vibrating kom zoo nrog lub sijhawm txaus ntawm kev co kom de-aerate cov pob zeb.
Yuav ua li cas kuv thiaj tso tsis tau honeycomb?
Siv cov koob nyias hais tias 25mm lossis tsawg duanrog vibrator ntawm qhov chaw sib txawv ntawm kev ua vaj tse kuj yuav pab txo cov zib ntab kom zoo. Taping nrog ntoo rauj ntawm ob sab ntawm kev kaw los ntawm sab nraud thaum lub sijhawm ua vaj tse yuav pab txo qis honeycombs mus rau qhov zoo.
