Kuyerekeza kwa Magwiridwe a PP ndi HDPE, Zida Ziwiri Zomwe Amagwiritsidwa Ntchito Pamabotolo a Reagent

Ndi kukulitsa kosalekeza kwa kuchuluka kwa ntchito za zida zosiyanasiyana za polima, mabotolo apulasitiki a reagent pang'onopang'ono akhala akugwiritsidwa ntchito kwambiri posungira zinthu zopangira mankhwala.Zina mwazinthu zopangira mabotolo apulasitiki opangira pulasitiki, polypropylene (PP) ndi polyethylene yapamwamba kwambiri (HDPE) ndi zida ziwiri zomwe zimagwiritsidwa ntchito kwambiri.Ndiye pali kusiyana kotani pakuchita pakati pa zida ziwirizi?

1)TmlengalengaRkukana

Kutentha kwa embrittlement kwa HDPE ndi -100 ° C ndipo kwa PP ndi 0 ° C.Chifukwa chake, zinthu zikafunika kusungirako kutentha pang'ono, mabotolo a reagent opangidwa ndi HDPE amakonda kwambiri, monga ma buffers a 2-8 ° C omwe amagwiritsidwa ntchito posungira zowunikira.Mabotolo a reagent a Buffer ndi -20 ° C enzyme;

2) ChemicalRkukana

Mabotolo a reagent opangidwa ndi HDPE ndi PP onse ndi asidi ndi alkali osamva kutentha kwa chipinda, koma HDPE ndiyabwino kuposa PP potengera kukana kwa okosijeni.Chifukwa chake, posungira zinthu zopangira oxidizing, mabotolo a HDPE reagent ayenera kusankhidwa;

Low molecular kulemera aliphatic hydrocarbons, onunkhira ma hydrocarbons ndi chlorinated hydrocarbons amatha kufewetsa ndi kutupa polypropylene.Choncho, mabotolo a HDPE reagent ayenera kugwiritsidwa ntchito posunga zosungunulira za organic monga mphete za benzene, n-hexane ndi ma hydrocarboni a chlorinated.

3) Kulimba komanso kukana kwamphamvu

Polypropylene (PP) ili ndi kukana kutopa kwambiri kwa kupindika, koma kukana kwamphamvu pakutentha kochepa.Kukana kwa mabotolo a HDPE reagent ndikobwino kwambiri kuposa mabotolo a PP reagent, chifukwa chake mabotolo a PP sali oyenera kusungirako kutentha pang'ono.

4)Tkusazindikira

PP ndi yowonekera kwambiri kuposa HDPE ndipo imathandizira kwambiri kuwona momwe zinthu zosungidwa mubotolo zilili.Komabe, mabotolo owoneka bwino a PP pamsika pano ali ndi wowonjezera wowonekera pazinthuzo, chifukwa chake muyenera kusamala posankha botolo la reagent lopangidwa ndi PP.

5) Njira yotseketsa

Pankhani ya njira zobereketsa, kusiyana kokha pakati pa HDPE ndi PP ndikuti PP ikhoza kutsekedwa ndi kutentha kwambiri komanso kuthamanga kwambiri, koma HDPE singathe.Zonsezi zitha kutsekedwa ndi EO komanso ma radiation (PP yolimbana ndi radiation ndiyofunika, apo ayi imasanduka yachikasu) ndipo Mankhwala ophera tizilombo amatenthetsa.
