Cia Thiab Thauj Cov Nruas Yas

Tus qauv ntsuas kub tsis kam rau High-Density Polyethylene (HDPE) nruas yas yog nruab nrab ntawm -50℃thiab +70 degree, txawm hais tias lawv tuaj yeem tiv taus qhov kub ntawm kwv yees li 100℃rau lub sijhawm luv. Thaum lub sij hawm cia, lub nruas yuav tsum tau muab tso rau hauv qab kom tsis txhob raug tshav ntuj ncaj qha; Qhov siab tshaj plaws kev pab cuam qhov kub thiab txias yog 60 degree, thaum pom zoo cia kub yog qis dua 40 degree. Thaum stacking, yuav tsum tau saib xyuas kom ntseeg tau tias cov pawg yog theem thiab cov nruas nyob rau hauv cov khaubncaws sab nraud povtseg sab sauv thiab sab qis kom zoo; staggered stacking yog nruj me ntsis txwv tsis pub. Yog tias cov khoom tau ntim rau hauv lub nruas siab tshaj 40 degree, nws yuav tsum tau tso cai kom txias rau ambient kub ua ntej lub kaus mom nruj thiab lub nruas yog stacked.

Ua ntej khaws cia thiab kev thauj mus los, cov nruas yas yuav tsum tau kuaj xyuas kev ua haujlwm raws li cov qauv tsim nyog. Piv txwv ntawm cov kev sim no suav nrog kev sim stacking (raws li GB / T 4857.3-2008), kev sim airtightness (raws li GB / T 17344-1998), kev ntsuas hydraulic (raws li GB 18191-2008), thiab kev sim poob (raws li GB / T 4857.5-1992). Cov kev ntsuam xyuas no yog tsim los xyuas kom muaj kev ncaj ncees ntawm cov ntim khoom thaum lub sij hawm thauj mus los thiab stacking txheej txheem.

Raws li qhov yuav tsum tau ua ntawm tus qauv *GB 18191-2008: Ntim Cov Thawv-Plastic Drums rau ntim cov khoom txaus ntshai*, cov khoom pov tseg uas muaj kev phom sij (xws li cov kua dej hauv chav kuaj) yuav tsum muaj nyob rau hauv cov nruas yas ntawm lub peev xwm. Tsis tas li ntawd, qhov ntim ntim yuav tsum tsis pub tshaj 75% ntawm lub nruas tag nrho lub peev xwm, thiab cov pa xau- pov thawj pallet yuav tsum muab tso rau hauv qab lub nruas. Kev siv cov nruas yas zoo tib yam kom muaj cov kua dej uas muaj hluav taws kub - xws li roj av - yog txwv tsis pub, vim qhov no ua rau muaj kev pheej hmoo ntawm kev tawg vim muaj hluav taws xob zoo li qub. Yog tias cov ntaub ntawv zoo li no yuav tsum muaj, tshwj xeeb los tiv thaiv- cov nruas zoo li qub yuav tsum tau siv, thiab ua raws li cov txheej txheem ua haujlwm nruj me ntsis- xws li tswj tus nqi sau thiab ua kom zoo hauv av-yog yuav tsum tau ua. Piv txwv ntawm cov khoom txaus ntshai uas yuav raug thauj hauv cov nruas yas no suav nrog acetic acid, hydrochloric acid, thiab sulfuric acid; hloov pauv, piv txwv ntawm cov khoom uas * tsis tuaj yeem * thauj hauv cov nruas no suav nrog fuming sulfuric acid, concentrated nitric acid, benzene, thiab roj av.
