    Kev Qhia Tshwj Xeeb:

    QAUV Nominal Txoj kab uas hla Xov Tus Nqi Nqus K Factor Qauv
    ZSTDY DN15 R1/2 80 ± 4 5.6 lub tshuab txau hluav taws zais cia
    DN20 R3/4 115±6 8.0

    Yuav siv li cas:

    Lub hau ntawm lub tshuab txau dej tua hluav taws zais tau vuam rau ntawm cov xov nrog cov hlau fusible, qhov chaw yaj yog 57 degrees. Yog li ntawd, thaum muaj hluav taws, thaum qhov kub nce siab, lub hau yuav raug tshem tawm ua ntej, thiab thaum qhov kub nce mus txog 68 degrees dua (feem ntau yog lub tshuab txau dej), lub raj iav tawg thiab dej ntws. Yog li ntawd, qhov txwv tshaj plaws ntawm lub taub hau txau dej tua hluav taws zais yog tias lub hau yog npog nrog xim thiab xim roj, uas yuav ua rau tsis ua haujlwm.
