Class A tiv thaiv hluav taws:
Class A cov khoom siv hluav taws kub yog ib yam khoom siv hluav taws xob siv hauv cov tsev siab.Cov tsev siab siab muaj hluav taws kub nyhiab heev vim hluav taws kub nyhiab hauv cov rwb thaiv tsev sab nraud, thiab cov qauv kev siv hluav taws xob hauv lub tebchaws tau maj mam nce ntawm 65% mus rau 75%.Nws yog ib qho kev tsis pom zoo uas cov kab hluav taws xob sab nraud yuav tsum tau xaiv cov khoom siv hluav taws kub hauv chav kawm A!Cov khoom siv no tsis tshua muaj kub hnyiab, thiab cov ntaub ntawv tuaj yeem ncav cuag qib no suav nrog cov ntaub plaub pob zeb, iav ntaub plaub, hloov kho polystyrene board, ua npuas ncauj iav, foamed cement, thiab cov hlau tshiab.
Class B1 tiv thaiv hluav taws:
Chav B1 yog cov khoom siv hauv tsev uas tsis muaj hluav taws kub, uas kav ntev tshaj li 1.5 teev, thiab lub sijhawm tshwj xeeb hluav taws kub kuj txawv nyob ntawm cov khoom siv.Cov khoom siv zoo li no muaj cov nplaim hluav taws zoo, txawm tias nws ntsib hluav taws, nws nyuaj rau kev pib hluav taws, thiab nws tsis yooj yim kom kis tau sai, thiab tib lub sijhawm, nws tuaj yeem nres hluav taws tam sim tom qab qhov hluav taws kub. raug thaiv.Cov ntaub ntawv uas tuaj yeem ncav cuag qib no suav nrog phenolic, roj hmab hmoov polystyrene, thiab tshwj xeeb kho extruded polystyrene (XPS) thiab polyurethane (PU).
Class B2 tiv thaiv hluav taws:
