Abakhiqizi bokubumba umjovoukuthenga izinhlayiya zepulasitiki ezifanelekayo, okuyisiqinisekiso esibalulekile sokuqinisekisa ukuthi imikhiqizo yokubumba umjovo ayinaphunga.Ngokuqondene namapulasitiki athile, anephunga elithile, abakhiqizi bokubumba umjovo badinga ukuthatha izinyathelo ezithile ngaphambi kokukhiqiza.
Imikhiqizo yokubumba umjovo ayidingeki nje kuphela ukuthi ifaneleke, kodwa uma izingxenye zokubumba ezikhiqizwayo zinephunga elingavamile, kuzoba nomthelela omubi kumakhasimende.Ikakhulukazi, abanye abakhiqizi bokubumba umjovo basebenzisa izinhlayiya zepulasitiki ezifanelekayo, futhi ukukhuphuka kwephunga elingavamile kuzothinta ngokuqondile ukuthengwa kwabathengi kwemikhiqizo.Ngakho, imikhiqizo kusetshenzwe ngokusebenzisaumjovo isikhuntakudingeka kuqinisekiswe ukuthi ayinalo iphunga elingavamile eliyingozi.
1. Lawula ngokuqinile ukusetshenziswa kwezithasiselo
I-catalyst tertiary amine esetshenziswa ekukhiqizeni igwebu le-polyurethane izoletha iphunga elinamandla nenkungu efasiteleni langaphakathi lemoto.Singathola ezinye esikhundleni salezi amines ukusebenzisa i-polyhydroxy compounds.Izinhlanganisela ze-Polyhydroxy azizona nje izingxenye zeketanga le-polyurethane yamangqamuzana, kodwa futhi zinomsebenzi okhuthazayo.Ezinye izinhlanganisela ze-polyhydroxy zingashintsha ngisho nengxenye ye-tertiary amine catalyst, Iphunga lemikhiqizo yokubumba umjovo iba buthaka.
2. Khetha inhlaka ehlanzekile ngaphezulu
Ezikhunjini eziningi zepulasitiki, ikakhulukazi kuI-PVC, i-styrene, i-poly (i-ethyl acetate) ne-acrylate, inani elisele lensalela lama-monomers lizoba nephunga elingemnandi.Uma i-resin engenaphunga ikhethiwe, umphumela uzoba ngcono.
3. Naka ukusetshenziswa kwe-adsorbent
Uma ama-zeolite ambalwa agcwaliswa ku-polymer, iphunga lezinto ezibonakalayo lingasuswa.Ama-Zeolite ane-crystal hollowness eningi, ekwazi ukuthwebula lawo ma-molecule amancane egesi ngephunga.
Abakhiqizi bokubumba umjovo bathenga izinhlayiya zepulasitiki ezifanelekayo, okuyisiqinisekiso esibalulekile sokuqinisekisa lokhoimikhiqizo yokubumba umjovoazinaphunga.Ngokuqondene namapulasitiki athile, anephunga elithile, abakhiqizi bokubumba umjovo badinga ukuthatha izinyathelo ezithile ngaphambi kokukhiqiza.
