Ukukhethwa kanye nokusetshenziswa PP/HDPE amabhodlela reagent

Amabhodlela ama-reagent angasetshenziselwa ukugcinwa nokuthuthwa kwamakhemikhali akhethekile, ama-reagents okuxilonga, imikhiqizo yezinto eziphilayo, ama-reagents, ama-adhesives kanye nezidakamizwa zezilwane.Njengamanje, impahla yamabhodlela e-reagent iningi lengilazi nepulasitiki, kepha ingilazi ithambile futhi ukuhlanza kunzima kakhulu.Ngakho-ke, amabhodlela e-plastic reagent anokusebenza okuqinile kwemishini kanye ne-asidi nokugqwala kwe-alkali kancane kancane abe yinketho ethandwayo emakethe.I-High density polyethylene (HDPE) ne-polypropylene (PP) yizinto ezimbili zepulasitiki ezivame ukusetshenziswa.Kufanele sizikhethe kanjani lezi zinhlobo ezimbili zamabhodlela ama-reagent?

1. Ukubekezelela izinga lokushisa

Impahla ye-HDPE imelana nokushisa okuphansi kanye nokushisa okuphezulu, ngakho-ke lapho isitoreji sokushisa esiphansi sidingeka, amabhodlela e-reagent amaningi enziwe ngezinto ze-HDPE akhethiwe;Impahla ye-PP imelana nokushisa okuphezulu kanye nezinga lokushisa eliphansi, lapho izinga lokushisa eliphakeme le-autoclave lidingeka, ibhodlela le-reagent lempahla ye-PP kufanele likhethwe.

2.Ukumelana namakhemikhali

Kokubili impahla ye-HDPE nezinto ze-PP zimelana ne-asidi-alkali, kodwa impahla ye-HDPE ingcono kunempahla ye-PP ngokokumelana ne-oxidation.Ngakho-ke, ekugcinweni kwama-reagents oxidizing, njenge-benzene rings, i-n-hexane, ama-hydrocarbons ane-chlorinated nezinye izinyibilikisi eziphilayo, kufanele kukhethwe impahla ye-HDPE.

3.Indlela yokuvala inzalo

Endleleni yokuvala inzalo, umehluko phakathi kwezinto ze-HDPE nezinto ze-PP ukuthi i-PP ingenziwa inzalo ekushiseni okuphezulu nokucindezela okuphezulu, futhi i-HDPE ayikwazi.Kokubili okokusebenza kwe-HDPE ne-PP kungenziwa inzalo nge-EO, i-irradiation (iyadingeka i-PP emelana nemisebe, ngaphandle kwalokho izoba phuzi) nesibulala-magciwane.

4.Umbala nokucaca

Umbala webhodlela le-reagent ngokuvamile ungokwemvelo (i-translucent) noma ensundu, amabhodlela ansundu anomphumela omuhle kakhulu we-shading, angasetshenziswa ukugcina ama-reagents amakhemikhali achithwa kalula ngokukhanya, njenge-nitric acid, i-nitrate yesiliva, i-hydroxide yesiliva, amanzi e-chlorine, njll., amabhodlela emvelo asetshenziselwa ukugcina ama-reagents amakhemikhali ajwayelekile.Ngenxa yethonya lesakhiwo samangqamuzana, izinto ze-PP zisobala kakhulu kune-HDPE impahla, evumelana kakhulu nokubheka isimo sezinto ezigcinwe ebhodleleni.

Kungakhathaliseki ukuthi i-PP impahla noma ibhodlela le-reagent ye-HDPE yezinto ezibonakalayo, ngokusho kwezici zayo ezibonakalayo, kukhona ezifanele uhlobo lwama-reagents amakhemikhali, ngakho-ke izici zama-reagents amakhemikhali kufanele zicatshangelwe lapho kukhethwa ibhodlela le-reagent.
