Cia peb saib ntau npaum li cas cov ntaub ntawv raw tau nce mus.Copper nce 38 feem pua, plastics 35 feem pua ​​thiab txhuas 37 feem pua, raws li official data.Iron yog nce 30 feem pua.Cov iav yog nce 30 feem pua.Cov hlau tshiab nce 48 feem pua.Stainless steel nce 45 feem pua.Dab tsi yog qhov laj thawj tseem ceeb tom qab qhov nce ntawm cov khoom siv raw?Industry insiders ntseeg hais tias muaj plaub lub ntsiab yog vim li cas rau steel nqi nce:

(1) lub ntiaj teb kev tsis sib haum xeeb ntawm cov khoom siv tau txhawb kev nce ntawm cov nqi raw khoom;

(2) Qhov kev thov sab ntawm cov hlau yog qhov ruaj khov, tswj kev ruaj ntseg ntawm cov hlau phaj yooj yim;

(3) Kev lag luam kev lag luam yog qhov siab, txhawb nqa qhov kev xav tau ntawm cov hlau;

(4) Xyoo no, cov khoom lag luam tau muab tso rau hauv kev tsim cov cai muaj feem xyuam, kev ua lag luam yuav tsum txhawb txoj cai, cov khoom siv hlau yuav muaj qee qhov kev cog lus.

Qhov ntim thiab tus nqi ntawm cov khoom siv hlau tau nce ua ke, kuj tau ua rau lub lag luam kub steel, ib feem ntawm cov tuam txhab lag luam steel xaj kom loj hlob ob npaug, qee qhov kev lag luam steel kev lag luam kev lag luam tau nce mus txog qhov siab tshaj plaws hauv keeb kwm.Tshuaj nyob rau hauv kev sib kis thoob ntiaj teb txij li xyoo 2020, Ntxiv nrog rau kev tswj kom muaj zog hauv peb lub teb chaws, lwm lub tebchaws tseem nyob hauv qhov cuam tshuam ntawm qhov tshwm sim ntawm qhov pib tam sim no, nyob rau hauv kev cuam tshuam ntawm qhov tshwm sim, ntau lub lag luam ntawm kev tsim khoom raug cuam tshuam tag nrho, xws li tsheb chip kev lag luam, cuam tshuam los ntawm Qhov tshwm sim ntawm lub ntiaj teb no tsis txaus ntawm cov khoom siv chips nyob rau hauv tide, tau txais kev tswj tag nrho ntawm kev kis tus kab mob ua ntej, Nws xav tias tus nqi ntawm cov khoom siv raw thiab cov khoom siv dav hlau yuav nce ntxiv rau xyoo 2021. Tib lub sijhawm, tib neeg cov nyiaj tau los poob qis vim rau qhov cuam tshuam ntawm kev sib kis. Yog li ntawd, peb yuav tsum kawm txog kev npaj nyiaj txiag kom tsis txhob muaj nyiaj tsawg thaum nws los txog rau lub sijhawm.
