Cov nqi dichloromethane hauv tebchaws (DCM) tau ruaj khov hauv lub sijhawm dhau los, tom qab kev poob qis thaum lub sijhawm so. Qhov kev poob qis ntawm tus nqi tau txhawb nqa qee qhov kev rov ua dua tshiab los ntawm cov tub luam thiab cov neeg yuav khoom tom qab, txhawb nqa cov khoom xa tuaj zoo rau cov neeg tsim khoom, tshwj xeeb tshaj yog cov neeg muab tus nqi qis dua, thiab pab txo cov khoom muag.
Txawm li cas los xij, qhov kev thov tseem tsis muaj zog. Cov neeg siv khoom siv tau zoo feem ntau tau tshaj tawm tias lawv xav tau khoom sai sai, thaum cov neeg xa khoom xa tawm hais tias lawv tsis muaj kev txiav txim tshiab, ua rau kev siv khoom tsis zoo. Lub peev xwm yuav khoom hauv khw tseem tsawg txawm tias muaj kev yuav khoom raws li lub sijhawm.
Cov Ntsiab Lus Tseem Ceeb ntawm Kev Lag Luam:
Cov Khoom Muag: Cov khoom muag ntawm cov neeg tsim khoom yog nyob rau theem nruab nrab, thaum cov khoom muag uas cov neeg siv khoom thiab cov tub luam tuav tseem nyob qis mus rau nruab nrab.
Tus nqi: Tus nqi ntawm cov kua chlorine uas nce ntxiv tas li muab kev txhawb nqa zoo rau DCM, ua kom yooj yim rau kev poob qis.
Kev Xav Tau: Kev xa khoom yuav raug txais tos hnub no, tej zaum yuav ua rau cov khoom muag ntawm cov chaw tsim khoom ruaj khov. Txawm li cas los xij, kev xav tau tseem ceeb los ntawm cov khoom siv kawg yog qhov kev txwv tseem ceeb ntawm kev ua lag luam.
Kev Kwv Yees Nqe:
Cov nqi yuav nyob ruaj khov hauv cov lag luam loj niaj hnub no.
Thaj Tsam Shandong: Cov nqi kwv yees tias yuav nyob hauv thaj tsam ntawm RMB 1,630 - 1,680 ib tonne.
Thaj Chaw Jiangsu-Zhejiang: Cov nqi kwv yees tias yuav ruaj khov, ntawm RMB 1,600 - 1,870 ib tonne.
Tam sim no kev ua lag luam raug ntes ntawm kev txhawb nqa tus nqi ruaj khov thiab qhov kev thov tsis tshua muaj zog, tej zaum yuav ua rau muaj kev txav mus rau sab hauv lub sijhawm luv luv.
