Isbarbardhigga Waxqabadka PP iyo HDPE, Laba Walxood oo Ceyriin ah oo Caadi ahaan Loo Isticmaalo Dhalooyinka Reagent

Iyada oo balaadhinta joogtada ah ee baaxadda codsiga ee agabyada kala duwan ee polymer, dhalooyinka reagent caag ah ayaa si tartiib tartiib ah loogu isticmaalay kaydinta reagents kiimikaad.Waxaa ka mid ah alaabta ceeriin ee soo saarista dhalooyinka reagent caag ah, polypropylene (PP) iyo polyetylen cufnaanta sare (HDPE) waa laba shay oo caadi ahaan la isticmaalo.Haddaba maxay ku kala duwan yihiin waxqabadka labadan agab?

1)TemperatureRdareen

Heerkulka hoos u dhaca HDPE waa -100 ° C iyo PP waa 0 ° C.Sidaa darteed, marka alaabtu u baahdaan kaydinta heerkulka hooseeya, dhalooyinka reagent ee ka samaysan HDPE ayaa aad loo door bidaa, sida 2-8°C baffers loo isticmaalo in lagu kaydiyo reagents ogaanshaha.Dhalooyinka reagent ee Buffer iyo -20°C enzyme;

2) KiimikadaRdareen

Dhalooyinka reagent ee laga sameeyay HDPE iyo PP labaduba waa aashito iyo alkali u adkaysta heerkulka qolka, laakiin HDPE way ka sarreeyaan PP marka loo eego iska caabinta oksaydhka.Sidaa darteed, marka la kaydinayo walxaha oksaydhaynta, dhalooyinka reagent HDPE waa in la doortaa;

Hydrocarbons aliphatic miisaan yar, hydrocarbons caraf udgoon iyo koloriin hydrocarbons ayaa jilicsan oo barara polypropylene.Sidaa darteed, dhalooyinka reagent HDPE waa in la isticmaalaa marka la kaydinayo dareerayaasha organic sida giraanta benzene, n-hexane iyo hydrocarbons koloriin leh.

3) Adkaynta iyo iska caabinta saamaynta

Polypropylene (PP) waxay leedahay iska caabin daal foorarsi heer sare ah, laakiin iska caabin xun oo heerkul hoose ah.Iska caabbinta hoos u dhaca dhalooyinka reagent HDPE ayaa aad uga wanaagsan tan dhalooyinka reagent PP, markaa dhalooyinka PP kuma habboona kaydinta heerkulka hooseeya.

4)Tdaahsoon

PP waa ka hufanaan badan yahay HDPE oo aad bay ugu habboon tahay in la eego xaaladda walxaha lagu kaydiyo dhalada.Si kastaba ha noqotee, dhalooyinka PP ee hufan ee suuqa hadda waxay leeyihiin wakiil hufan oo lagu daray walxaha, markaa waxaad u baahan tahay inaad fiiro gaar ah u yeelato markaad dooranayso dhalada reagent ka samaysan PP.

5) Habka jeermiska

Marka la eego hababka jeermiska, farqiga kaliya ee u dhexeeya HDPE iyo PP waa in PP lagu jeermiyo heerkulka sare iyo cadaadiska sare, laakiin HDPE ma awoodo.Labadaba waxaa lagu jeermi karaa EO iyo shucaac (PP-ga u adkaysta shucaaca ayaa loo baahan yahay, haddii kale waxay isu rogi doontaa huruud) iyo jeermiska jeermiska dila.
