Pob hlau tsis xeb - Cov yam ntxwv zoo thiab cov kev xav tau ntawm cov hlau tsis xeb

Daim ntawv thov ntawm cov hlau tsis xeb hauv kev tsim cov tshuab kev lag luam yog dav heev, thiab ua lub luag haujlwm tseem ceeb. Cov hlau tsis xeb raws li nws tus kheej cov yam ntxwv ntawm tus qauv qauv yog txawv, kev siv yog txawv. Thiab kuj los ntawm cov hlau tsis xeb nws tus kheej cov khoom siv raw. Thiab cuam tshuam los ntawm ntau yam mob, qhov nyuaj ntawm cov hlau tsis xeb kuj txawv.

(1) Cov Khoom Siv:

① DDQ (zoo kos duab tob): Hais txog cov khoom siv rau kev kos duab tob (punching), uas yog, cov khoom mos peb hais, cov yam ntxwv tseem ceeb ntawm cov khoom siv no yog qhov ntev siab (≧ 53%), qhov nyuaj tsawg (≦ 170%), qib nplej sab hauv ntawm 7.0 ~ 8.0, kev ua tau zoo heev kos duab tob. Tam sim no, ntau lub tuam txhab uas tsim cov raj mis thermos thiab POTS, qhov piv ntawm kev ua tiav ntawm lawv cov khoom (BLANKING SIZE / khoom txoj kab uas hla) feem ntau yog siab, thiab lawv qhov piv ntawm kev ua tiav yog 3.0, 1.96, 2.13, thiab 1.98, raws li. Cov ntaub ntawv SUS304 DDQ feem ntau yog siv rau cov khoom no uas xav tau qhov piv ntawm kev ua tiav siab dua, tau kawg, cov khoom nrog qhov piv ntawm kev ua tiav ntau dua 2.0 feem ntau yuav tsum tau ua tiav tom qab ntau qhov ncab. Yog tias qhov kev nthuav dav ntawm cov khoom siv raw tsis tuaj yeem ncav cuag, qhov tshwm sim ntawm kev tawg thiab rub los ntawm yog qhov yooj yim tshwm sim hauv kev ua cov khoom sib sib zog nqus, uas cuam tshuam rau tus nqi tsim nyog ntawm cov khoom tiav, thiab ntawm chav kawm nce tus nqi ntawm cov chaw tsim khoom;

② Cov ntaub ntawv dav dav: Feem ntau siv rau cov ntaub ntawv uas tsis yog DDQ lub hom phiaj, cov ntaub ntawv no yog tus cwj pwm los ntawm qhov ntev me me (≧ 45%), qhov nyuaj siab heev (≦180), qib loj ntawm cov noob sab hauv ntawm 8.0 thiab 9.0, piv nrog cov ntaub ntawv DDQ, nws qhov kev ua tau zoo kos duab tob tsis zoo, nws feem ntau yog siv rau cov khoom uas tuaj yeem tau txais yam tsis muaj kev ncab. Zoo li ib hom diav tais diav, diav rawg, rab diav rawg, cov khoom siv hluav taws xob, cov yeeb nkab hlau siv. Txawm li cas los xij, nws muaj qhov zoo dua piv nrog cov ntaub ntawv DDQ, uas yog, cov cuab yeej BQ zoo heev, feem ntau vim nws qhov nyuaj me ntsis.
