Ka Hoʻohālikelike Hana ʻana o PP a me HDPE, ʻElua mau mea maʻamau i hoʻohana ʻia no nā ʻōmole Reagent

Me ka hoʻomau mau ʻana o ka hoʻohana ʻana o nā mea polymer like ʻole, ua hoʻohana nui ʻia nā ʻōmole reagent plastic i ka mālama ʻana i nā reagents kemika.Ma waena o nā mea maka no ka hana ʻana i nā ʻōmole reagent plastic, polypropylene (PP) a me ka polyethylene kiʻekiʻe (HDPE) ʻelua mau mea maʻamau.No laila he aha ka ʻokoʻa o ka hana ma waena o kēia mau mea ʻelua?

1)TemperatureResistance

ʻO ka mahana embrittlement o HDPE he -100°C a ʻo ka PP he 0°C.No laila, inā makemake nā huahana i kahi mālama haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o nā hue reagent i hana ʻia me HDPE, e like me 2-8 ° C buffers i hoʻohana ʻia e mālama i nā reagents diagnostic.ʻO nā'ōmole Reagent no Buffer a me -20 ° C enzyme;

2) KemikaResistance

ʻO nā ʻōmole Reagent i hana ʻia me ka HDPE a me ka PP ʻelua ka waikawa a me ka alkali kū i ka lumi mahana, akā ʻoi aku ka HDPE ma mua o PP ma ke ʻano o ka pale ʻana i ka oxidation.No laila, i ka wā e mālama ai i nā mea oxidizing, pono e koho ʻia nā ʻōmole reagent HDPE;

Hiki ke hoʻoluliluli a pehu ka polypropylene me ka haʻahaʻa molecular weight aliphatic hydrocarbons, aromatic hydrocarbons a me chlorinated hydrocarbons.No laila, pono e hoʻohana ʻia nā ʻōmole HDPE reagent i ka wā e mālama ai i nā solvents organik e like me nā apo benzene, n-hexane a me nā hydrocarbons chlorinated.

3) ʻO ka paʻakikī a me ke kū'ē i ka hopena

ʻO ka Polypropylene (PP) maikaʻi loa ka pale ʻana i ka luhi, akā maikaʻi ʻole ka hopena i ka haʻahaʻa haʻahaʻa.ʻOi aku ka maikaʻi o ka hāʻule ʻana o nā hue HDPE reagent ma mua o nā hue PP reagent, no laila ʻaʻole kūpono nā hue PP no ka mālama haʻahaʻa haʻahaʻa.

4)Tkūʻai kālā

ʻOi aku ka mālamalama o PP ma mua o HDPE a ʻoi aku ka maikaʻi o ka nānā ʻana i ke kūlana o nā mea i mālama ʻia i loko o ka hue.Eia nō naʻe, ʻo nā hue PP maʻemaʻe loa ma ka mākeke i kēia manawa ua hoʻohui ʻia kahi mea hoʻohui i ka mea, no laila pono ʻoe e hoʻolohe i ke koho ʻana i kahi hue reagent i hana ʻia me PP.

5) Keʻano o ka sterilization

Ma ke ʻano o nā ʻano sterilization, ʻo ka ʻokoʻa wale nō ma waena o HDPE a me PP ʻo ia ka PP hiki ke sterilized e ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe, akā ʻaʻole hiki i ka HDPE.Hiki ke hoʻopaʻa ʻia nā mea ʻelua e ka EO a me ka radiation (pono ʻia ka irradiation-resistant PP, i ʻole e huli melemele) a sterilize nā Disinfectants.
