** 1. Dab tsi yog cov khoom siv ntawm cov yeeb nkab steel? **
Ib cov yeeb nkab steel yog feem ntau ua los ntawm cov hlau thiab carbon thiab carbon, uas yog lub hauv paus ntsiab lus ntawm cov hlau. Other alloying elements, such as manganese, chromium, nickel, or molybdenum, are often added in varying amounts to achieve specific properties like increased strength, corrosion resistance, or ductility.
** 2. Dab tsi yog feem ntau cov khoom siv hlau siv hauv cov kav dej? **
Feem ntau cov khoom siv hlau siv rau cov kav dej yog cov hlau. Cov qhab nia tshwj xeeb xws li A53 thiab A106 (rau qhov siab thiab cov kev pab kub, thiab cov khoom siv roj av thiab cov roj av, durability, thiab tus nqi- ua hauj lwm zoo.
** 3. Dab tsi yog 4 hom hlau? **
Plaub hom hlau, cais tawm los ntawm lawv cov tshuaj lom neeg muaj pes tsawg leeg, yog:
* ** Carbon Steel: ** Hom hom, ua cov hlau thiab carbon. Nws yog paub txog nws lub zog thiab yog siv dav siv hauv kev tsim kho thiab kev tsim khoom.
* ** ALLOY STEEL: ** muaj cov ntsiab lus ntxiv (zoo li chromium, npib tsib xee, molybdenum) hauv cov khoom siv tseem ceeb, kev siv tawv me, kev ua haujlwm nruj, thiab hnav tsis kam.
* ** Feem pua Stainless: ** Muaj feem pua siab ntawm chromium (tsawg kawg 10,5%) uas muab rau nws tshwj tsis muaj kev zam corrosion thiab xeb tsis kam.
* ** Cov Steel Steel: ** Qhov nyuaj heev thiab hnav {{{}} {Resistant hom hlau, muaj cov ntsiab lus xws li Tupsten, Molybdenum, thiab Vanadium. Nws yog tshwj xeeb tsim los ua cov cuab yeej, tuag, thiab cov khoom siv txiav.
** 4. Cov khoom siv yog ib qho yeeb nkab ua los ntawm? **
Cov kav dej tuaj yeem tsim los ntawm ntau cov ntaub ntawv, xaiv raws li daim ntawv thov. Cov Khoom Siv Uas Muaj:
* ** MEHAL: ** STEEL (POB KHOB (CARBON (Stainless, Alloy), Tooj Liab, Tsev Pem, Hlau, Thiab Aluminium.
* ** PLASTSICE: ** PVC (HDYvinyl chloride), hdо (high- qhov ceev polyvinyl chloride)
* ** LWM COV NTAUB NTAWV: ** QHOB, av nplaum, thiab sib xyaw zoo li FRP (Fiberglass Reflefored yas).
** 5. Dab tsi yog cov khoom siv yeeb nkab feem ntau? **
Tsis muaj ib qho "feem ntau" cov khoom siv tso yeeb rau txhua daim ntawv thov, raws li nws muaj nyob ntawm kev siv rooj plaub siv:
* ** Rau cov dej hluav taws xob hauv zos: ** Tooj liab thiab PEX yas yog qhov muaj heev.
* ** Rau cov dej ntws tawm - khib - pa (DWV) (** PVC yas yog feem ntau.
* ** Rau cov dej hauv nroog thiab roj kis: ** Zas cov hlau thiab cov hlau muaj ntau heev.
* ** Rau cov ntawv thov kev lag luam Txuas tshuaj chemicals
Yog li ntawd, thaum ** ** PVC **
