Zotsatira za ufa wa latex pa mphamvu ya zida zapansi za simenti

Pankhani ya kusinthasintha ndi mphamvu yopondereza, pansi pa chiŵerengero cha madzi-simenti nthawi zonse ndi mpweya, kuchuluka kwa ufa wa latex kumakhudza kwambiri mphamvu zowonongeka ndi zopondereza za zipangizo zapansi za simenti. Ndi kuwonjezeka kwa ufa wa latex, mphamvu yowonongeka inachepa pang'ono, pamene mphamvu yowonongeka inakula kwambiri, ndiko kuti, chiŵerengero chopinda (compressive mphamvu / flexural mphamvu) pang'onopang'ono chinachepa. Izi zikuwonetsa kuti kuwonongeka kwa zipangizo zodzipangira pansi kumachepa kwambiri ndi kuwonjezeka kwa ufa wa latex. Izi zidzatsitsa modulus ya elasticity ya zinthu zodziyimira pawokha ndikuwonjezera kukana kwake kusweka.

Pankhani ya mphamvu yolumikizirana, popeza gawo lodziyimira pawokha ndi gawo lachiwiri lowonjezera; makulidwe omanga a gawo lodzipangira okha nthawi zambiri amakhala ochepa kuposa matope wamba; Wosanjikiza wosanjikiza amafunika kukana kupsinjika kwamafuta kuchokera kuzinthu zosiyanasiyana; nthawi zina zida zodziyimira pawokha zimagwiritsidwa ntchito pazinthu zapadera monga malo oyambira omwe ndi ovuta kutsatira: Chifukwa chake, ngakhale ndi othandizira othandizira othandizira mawonekedwe, kuti awonetsetse kuti gawo lodziyimira pawokha likhoza kumangirizidwa mwamphamvu pamwamba. kwa nthawi yayitali Pazigawo zoyambira, kuwonjezera kuchuluka kwa ufa wa latex kumatha kuonetsetsa kuti nthawi yayitali komanso yodalirika kumamatira kwazinthu zodzipangira okha.

Mosasamala kanthu kuti ili pamtunda wotsekemera (monga konkire yamalonda, ndi zina zotero), maziko a organic (monga nkhuni) kapena maziko osasunthika (monga zitsulo, monga sitima yapamadzi), mphamvu ya mgwirizano wa zinthu zodziyimira pawokha zimasiyanasiyana ndi kuchuluka kwa ufa wa latex. Kutengera mawonekedwe a kulephera mwachitsanzo, kulephera kwa mayeso a mphamvu ya bond ya zinthu zodziyimira pawokha zosakanikirana ndi ufa wa latex zonse zidachitika pazinthu zodziyimira pawokha kapena m'munsi pamwamba, osati pamawonekedwe, zomwe zikuwonetsa kuti kugwirizana kwake kuli bwino. .
