Lub raj mis cawv yog tsim los ntawm ntau cov ntaub ntawv, uas tuaj yeem muab faib ua hom hauv qab no raws li kev muaj pes tsawg leeg: ib qho yog sodium iav, lwm qhov yog iav iav, thiab qhov thib peb yog iav borosilicate. Cov ntaub ntawv tseem ceeb ntawm cov iav fwj yog ntuj ore, quartz pob zeb, caustic soda, limestone, thiab lwm yam. Cov iav fwj muaj qhov pom tseeb thiab corrosion tsis kam, thiab cov khoom siv yuav tsis hloov thaum sib cuag nrog cov tshuaj feem ntau.
Cov iav iav fwj tau siv dav vim tias lawv tsis muaj tshuaj lom, tsis qab, pob tshab, zoo nkauj, zoo thaiv, airtight, nplua nuj nyob rau hauv raw cov ntaub ntawv, tsis tshua muaj nqi, thiab yuav siv tau ntau zaus. Thiab nws muaj qhov zoo ntawm kev ua kom sov, ua haujlwm siab thiab ntxuav, thiab nws tuaj yeem ua kom tsis muaj menyuam ntawm qhov kub thiab txias los yog khaws cia ntawm qhov kub thiab txias. Thiab ntau lwm yam zoo, nws tau siv dav hauv cawv, npias thiab lwm yam kev lag luam, thiab tam sim no nws kuj tau siv dav hauv kev lag luam khoom noj thiab dej haus.
Cia kev paub txog iav cawv fwj
Cov iav iav fwj muaj ntau yam zoo, xws li cov khoom thaiv kev tiv thaiv, zoo rwb thaiv tsev, pob tshab thiab zoo nkauj, tab sis kuj muaj qhov tsis hloov pauv tsis zoo, xws li: iav tsis muaj zog, tsis zoo rau cov khoom siv, tsis zoo cuam tshuam, thiab yog raug rau qhov thib ob thaum tsoo tsoo, nws yooj yim tawg, thiab nws yog qhov nyuaj rau kev thauj mus los thiab tus nqi siab. Nws tuaj yeem ntim rau hauv pallets, thauj los ntawm lub tsheb lossis ntim rau hauv thawv. Qhov kev puas tsuaj ntawm cov thawv yog qhov tsawg tshaj plaws, tab sis tus nqi ntawm kev ntim khoom yog qhov siab tshaj plaws. Feem ntau, muaj tsib-txheej lossis peb-txheej corrugated cartons. Kev puas tsuaj rau cov iav fwj los ntawm kev sib tsoo ntawm cov khoom xa tuaj.
Nyob rau hauv txoj kev no, qhov cuam tshuam quab yuam ntawm lub khob cawv lub raj mis raug txo. Txawm hais tias lub sijhawm thauj mus los ntev, qhov kev puas tsuaj yog peb feem kaum ntawm qhov qub. Txawm hais tias lub khob cawv cawv tsis yog ib qho yooj yim khaws cia, tab sis nrog ntau qhov zoo, kev lag luam siv tus nqi tsis tau txo. Nws tau txawm nkag mus rau hauv dej haus, tshuaj tua kab, tshuaj pleev ib ce thiab lwm yam kev lag luam, thiab nws cov kev cia siab muag yog booming.
