These two additives, when mixed with the joint compound alone or in combination, produced a more flexible, higher strength wallboard with a reduce moisture content and quicker drying time.doi:US6402832 B1Bhima R. VijayendranGregory R. White...
An accelerator, such as zinc sulfate, may be added to the ready-mixed, cementitious composition to initiate the setting action, or the ready-mixed cementitious composition can be used as a drying type joint compound without the addition of an accelerator. 展开 ...
insufficient for any significant drying shrinkage to have taken place in a well cured slab. If the joints are sealed at this time it is likely that re-sealing will be required at a later date. If they are left unsealed all but the narrowest of joints may suffer damage, thus requiring so...

Here, we propose a two-in-one femtosecond laser writing strategy to fabricate microjoints composed of hydrogel and metal nanoparticles, and develop multi-joint microactuators with multi-deformation modalities (>10), requiring short response time (30 ms) and low actuation power (<10 mW) to ...
Chemical setting-type joint compounds are similar to cement in that they set instead of drying. This type of joint compound offers low shrinkage and resistance to cracking and humidity. As with cement, setting compounds adjust well to climate changes. ...
We find that 33.64−46.18% of flash droughts with 5-day onset of drying, and there is a significant increasing trend in the proportion of flash droughts with the 1-pentad onset time globally during the period 2000−2020. Flash droughts do not appear to be occurring more frequently in ...
or container for containing a selected quantity of premixed drywall joint compound of desired consistency to the job site for dispensing to construction workers as needed, which hopper is highly mobile, and is designed to retard drying of the joint compound for a considerable period of time. ...
Most commercial joint compound formulations contain limestone, clay, mica, resinous binder, thickener, lubricant and preservative in varying amounts. The resinous binder is normally a coalescable vinyl material, such as (poly)vinyl acetate and ethylene-vinyl acetate copolymer. Upon drying or curing of...
