Kev ceev faj rau kev nyab xeeb:
Tsis txhob tsim cov hmoov av. Tsis txhob ua pa pos huab, roj lossis vapors. Tsis txhob tiv nrog daim tawv nqaij thiab qhov muag. Siv cov cuab yeej tiv thaiv tus kheej. Hnav cov hnab looj tes uas tsis muaj tshuaj lom neeg. Xyuas kom muaj qhov cua txaus. Tshem tawm txhua qhov chaw ntawm qhov hluav taws kub. Tshem tawm cov neeg ua haujlwm mus rau thaj chaw nyab xeeb. Khaws cov neeg nyob deb ntawm thiab nce siab ntawm cov dej ntws tawm.
Cov txheej txheem thiab cov khoom siv rau kev ntim thiab ntxuav:
Sau thiab npaj pov tseg. Khaws cov tshuaj nyob rau hauv cov thawv tsim nyog thiab kaw kom pov tseg. Tshem tawm tag nrho cov khoom siv hluav taws xob. Siv cov cuab yeej pov thawj thiab cov khoom pov thawj tawg. Adhered los yog sau cov ntaub ntawv yuav tsum tau muab pov tseg tam sim ntawd, raws li txoj cai thiab kev cai tsim nyog.
20L ntawm High density polyethylene yas chim.
Muab ib lub hnab pov thawj lub teeb dub rau sab nraum lub thoob.
Cov khoom yuav tsum tau palletized nrog tsis fumigation ntoo pallets.
Jingye muaj 86 pawg ntawm cov reactors nyob rau hauv tag nrho, uas lub ntim ntawm enamel reactor yog 69, los ntawm 50 mus rau 3000L. Tus naj npawb ntawm stainless reactors yog 18, los ntawm 50 mus rau 3000L. QC tau nruab nrog ntau pua ntawm txhua yam kev ntsuas ntsuas. Nws tuaj yeem ua tau raws li kev lag luam ntau lawm thiab kev tsom xam ntawm cov khoom. Cov khoom no yog cov khoom lag luam zoo tshaj plaws thiab tuaj yeem xa tuaj raws li cov neeg siv khoom xav tau.
