Aṣayan ati ohun elo ti awọn igo reagent PP / HDPE

Awọn igo reagent le ṣee lo fun ibi ipamọ ati gbigbe ti awọn kemikali pataki, awọn reagents iwadii, awọn ọja ti ibi, awọn reagents, awọn adhesives ati awọn oogun ti ogbo.Ni lọwọlọwọ, ohun elo ti awọn igo reagent jẹ gilasi pupọ ati ṣiṣu, ṣugbọn gilasi jẹ ẹlẹgẹ ati mimọ jẹ diẹ sii.Nitorinaa, awọn igo reagent ṣiṣu pẹlu iṣẹ ẹrọ ti o lagbara ati acid ati ipata alkali ti di yiyan olokiki ni ọja naa.Polyethylene iwuwo giga (HDPE) ati polypropylene (PP) jẹ awọn ohun elo ṣiṣu meji ti a lo nigbagbogbo.Bawo ni o ṣe yẹ ki a yan iru awọn igo reagent meji wọnyi?

1. Ifarada iwọn otutu

Ohun elo HDPE jẹ sooro si iwọn otutu kekere ati iwọn otutu giga, nitorinaa nigbati o ba nilo ibi ipamọ otutu kekere, awọn igo reagent diẹ sii ti ohun elo HDPE ti yan;Ohun elo PP jẹ sooro si iwọn otutu giga ati iwọn otutu kekere, nigbati o ba nilo autoclave otutu otutu, igo reagent ti ohun elo PP yẹ ki o yan.

2.Chemical resistance

Mejeeji ohun elo HDPE ati ohun elo PP jẹ sooro acid-alkali, ṣugbọn ohun elo HDPE dara julọ ju ohun elo PP ni awọn ofin ti resistance ifoyina.Nitorinaa, ni ibi ipamọ ti awọn reagents oxidizing, gẹgẹbi awọn oruka benzene, n-hexane, hydrocarbons chlorinated ati awọn ohun elo Organic miiran, ohun elo HDPE yẹ ki o yan.

3.Sterilization ọna

Ni ọna sterilization, iyatọ laarin ohun elo HDPE ati ohun elo PP ni pe PP le jẹ sterilized ni iwọn otutu giga ati titẹ giga, ati HDPE ko le.Mejeeji HDPE ati awọn ohun elo PP le jẹ sterilized nipasẹ EO, irradiation (PP ti o ni ifarapa irradiation ni a nilo, bibẹẹkọ o yoo ofeefee) ati alakokoro.

4.Awọ ati akoyawo

Awọ ti igo reagent jẹ adayeba gbogbogbo (translucent) tabi brown, awọn igo brown ni ipa iboji ti o dara julọ, a le lo lati tọju awọn reagents kemikali ti o ni irọrun ti bajẹ nipasẹ ina, gẹgẹbi nitric acid, iyọ fadaka, hydroxide fadaka, omi chlorine, ati bẹbẹ lọ, awọn igo adayeba ni a lo lati tọju awọn reagents kemikali gbogbogbo.Nitori ipa ti eto molikula, ohun elo PP jẹ alaye diẹ sii ju ohun elo HDPE, eyiti o jẹ itara diẹ sii lati ṣe akiyesi ipo ti ohun elo ti a fipamọ sinu igo naa.

Boya ohun elo PP tabi HDPE igo reagent ohun elo, ni ibamu si awọn abuda ohun elo rẹ, o dara fun iru awọn reagents kemikali, nitorinaa awọn abuda ti awọn reagents kemikali yẹ ki o ṣe akiyesi nigbati o yan igo reagent.
