Conductive ntim hnab is a special packaging form of container bag, which is often used in the packaging of various chemical raw materials, which can play a very good role in preventing moisture and light, and the structure of these container bags is very reasonable. Generally, at least four-layer packaging structure is used to achieve better water and oxygen insulation. At the same time, this kind of packaging bag can be made into various shapes, whether users want flat mouth packaging or three-dimensional packaging, they can actually be modified and customized. Let's take a look at the specific aspects of the quality identification of this container bag.
Ua ntej, kev ua haujlwm ntawm kev sib cais yog qhov zoo. Qhov kev ua haujlwm rwb thaiv tsev no yog cov yam ntxwv tseem ceeb uas txhua lub hnab ntim khoom yuav tsum tau ntsib, suav nrog lub peev xwm los tiv thaiv oxidation, tsis muaj dej thiab lub teeb pov thawj, thiab cov khoom no yuav tsum muaj los ntawm cov hnab ntim khoom.
Thib ob, cov cuab yeej tiv thaiv - kev ua phem ua phem tau zoo. Qhov no yog ib qho kev ua tau zoo uas lwm lub hnab ntim khoom yuav tsis muaj, vim tias nws muaj lub zog tsim kua muag zoo heev, yog li nws qhov kev ua tau zoo hauv kev tawm tsam kev tawm tsam yog qhov pom tseeb dua.
Thib peb, nws tuaj yeem hloov kho qhov sib txawv ntawm qhov kub thiab txias. Los ntawm qhov kub siab tshaj ntawm 120 degrees mus rau qhov kub qis tshaj ntawm rho tawm 40 degrees, lub hnab ntim khoom no muaj kev hloov pauv tau zoo. Ntxiv rau qhov no, nws muaj corrosion thiab roj kuj zog. Tau kawg, nws yog qhov tseeb vim tias cov yam ntxwv no uas lig - lub hnab ntim cov theem muaj cov yas muaj zog heev, kev ua haujlwm zoo thaum tshav kub kub sealing, thiab zoo softness, uas tuaj yeem thaiv qhov kub ntawm sab nraud.
Plaub, tsis muaj ntxhiab tsw ntxhiab, thiab nws tuaj yeem hloov mus rau cov khoom ntim sib txawv, txawm tias cov khoom noj tuaj yeem ntim tau. Nws cov qauv kev tu cev ua tau raws li qhov xav tau ntawm kev ntim khoom noj. Ntawm chav kawm, qhov no kuj yog qhov tshwj xeeb muaj nuj nqi ntawm lub hnab ntim khoom conductive.
