Ukuthelekiswa kokuSebenza kwePP kunye ne-HDPE, iiMpahla eZimbini eziSetyenziswa ngokuqhelekileyo kwiibhotile zeReagent

Ngokwandiswa okuqhubekayo komda wesicelo sezinto ezahlukeneyo zepolymer, iibhotile zeplastiki ze-reagent ngokuthe ngcembe ziye zasetyenziswa ngokubanzi kwindawo yokugcina iikhemikhali.Phakathi kwezinto ezisetyenziselwa ukuveliswa kweebhotile zeplastiki ze-reagent, i-polypropylene (PP) kunye ne-high-density polyethylene (HDPE) zizinto ezimbini ezisetyenziswa ngokuqhelekileyo.Ngoko ke yintoni umahluko ekusebenzeni phakathi kwezi zixhobo zimbini?

1)Ti-emperatureRukungakhathali

Ubushushu be-embrittlement ye-HDPE yi--100 ° C kunye ne-PP yi-0 ° C.Ngoko ke, xa iimveliso zifuna ukugcinwa kweqondo lokushisa eliphantsi, iibhotile ze-reagent ezenziwe nge-HDPE zikhethwa ngakumbi, ezifana ne-2-8 ° C buffers ezisetyenziselwa ukugcina ii-reagents zokuxilonga.Iibhotile ze-reagent ye-Buffer kunye ne-20 ° C enzyme;

2) IkhemikhaliRukungakhathali

Iibhotile ze-Reagent ezenziwe nge-HDPE kunye ne-PP zombini i-asidi kunye ne-alkali yokumelana nokushisa kwegumbi, kodwa i-HDPE iphezulu kune-PP ngokwemiqathango yokumelana ne-oxidation.Ngoko ke, xa ugcina izinto ze-oxidizing, iibhotile ze-HDPE reagent kufuneka zikhethwe;

Ubunzima bemolekyuli ephantsi i-aliphatic hydrocarbons, ii-hydrocarbons ezinevumba elimnandi kunye ne-chlorinated hydrocarbons zinokuthambisa kwaye zidumbe i-polypropylene.Ngoko ke, iibhotile ze-HDPE ze-reagent kufuneka zisetyenziswe xa kugcinwa izinyibilikisi ze-organic ezifana ne-benzene rings, i-n-hexane kunye ne-chlorinated hydrocarbons.

3) Ukuqina kunye nokuchasana kwempembelelo

I-Polypropylene (PP) inokumelana nokugoba okugqwesileyo, kodwa ukuchasana nempembelelo embi kumaqondo obushushu aphantsi.Ukuchasana nokuhla kweebhotile ze-HDPE ze-reagent zingcono kakhulu kuneebhotile ze-PP, ngoko ke iibhotile ze-PP azifanelekanga ukugcinwa kobushushu obuphantsi.

4)Tukungafihli

I-PP icace ngakumbi kune-HDPE kwaye ilungele ukujonga imeko yezinto ezigcinwe kwibhotile.Nangona kunjalo, iibhotile zePP ezicacileyo ngokukodwa kwimarike ngoku zinearhente ecacileyo eyongezwe kwizinto eziphathekayo, ngoko kufuneka ubeke ingqalelo xa ukhetha ibhotile ye-reagent eyenziwe ngePP.

5) Indlela yokuvala inzala

Ngokweendlela zokuvala inzala, umahluko kuphela phakathi kwe-HDPE kunye ne-PP kukuba i-PP inokuthi ifakwe inzalo ngobushushu obuphezulu kunye noxinzelelo oluphezulu, kodwa i-HDPE ayikwazi.Zombini zinokuvalwa yi-EO kunye nemitha (i-PP enganyangekiyo kwimitha iyafuneka, kungenjalo iya kujika ibe tyheli) kwaye Izibulali-ntsholongwane ziyabulala iintsholongwane.
