ipulasitiki yegwebu
Ipulasitiki enegwebu uhlobo lwepulasitiki olutholakala ngokukhiqiza ngokomzimba noma ngamakhemikhali ukwakheka kwe-microcellular ngaphakathi kwepulasitiki.Lolu hlobo lwepulasitiki lunobuhle besisindo esilula, ukwahlukanisa ukushisa, ukugcinwa kwe-buffering, ukwahlukanisa, ukulwa nokugqwala kanye nenani eliphansi.Cishe wonke amapulasitiki e-thermosetting kanye ne-thermoplastic angenziwa abe amapulasitiki anegwebu.Amapulasitiki anegwebu avamile i-polystyrene, i-polyurethane, ne-polyolefin.
Ukuqhathaniswa kwamapulasitiki amathathu amakhulu anegwebu
Isingeniso se-Foamed Polypropylene
I-polypropylene enegwebu ipulasitiki enegwebu elungiswe nge-polypropylene njenge-resin eyisisekelo.Uma kuqhathaniswa namapulasitiki anegwebu asetshenziswa ngokuvamile, i-polypropylene enegwebu inezinzuzo eziningi.
I-polypropylene enegwebu impahla eluhlaza
Njengoba amandla aphansi ancibilika e-polypropylene evamile awakwazi ukuqinisekisa ukucindezelwa okuqinile ezindongeni zeseli lapho amabhamuza ekhula, i-polypropylene yokwenza amagwebu idinga ukusebenzisa i-polypropylene yamandla aphezulu aphezulu (HMSPP).
Izindlela zokuthuthukisa amandla okuncibilika kwe-polypropylene zihlanganisa ukuxubana ngokomzimba nokuguqulwa kwamakhemikhali.
Njengamanje, abakhiqizi bezinto zokusetshenziswa ze-polypropylene zamandla aphezulu ancibilika bahlanganisa i-Basell, i-Borealis, i-Dow Chemical, i-Samsung, i-Exxon Mobil, njll.Izikhungo eziningi zocwaningo lwasekhaya zenze ucwaningo oluningi ngobuchwepheshe obukhipha amagwebu, futhi abanye abakhiqizi sebekubonile ukukhiqizwa kwezimboni, njengeZhenhai Refinery, Yanshan Petrochemical Resin Research Institute, Wuhan Futiya, kodwa kusenegebe elikhulu phakathi kwekhwalithi yomkhiqizo namazwe angaphandle. ..
Inqubo yokukhiqiza ye-polypropylene enegwebu
Kunezinqubo ezintathu zokulungiselela eziyinhloko: amandla aphezulu ancibilika i-polypropylene Foaming, igwebu le-polypropylene elixhumene, kanye nenqubo yokuhlanganisa amagwebu.
Isihluthulelo sokulungiswa kwe-polypropylene enegwebu
Imikhiqizo ye-polypropylene enegwebu inokusebenza okuhle namathemba okusebenza, kodwa ukuthuthukiswa kobuchwepheshe kunzima.Ubuchwepheshe obuyisihluthulelo benqubo ye-polypropylene yokwenza amagwebu ukulawula ukuzinza kwegwebu kanye nesilinganiso sokugwedla se-polypropylene ngokulungisa izinga lokushisa lenqubo.
Izinkambu zokufaka isicelo se-polypropylene enegwebu
1. Ukupakishwa kokudla
I-polypropylene enegwebu inokonakala okuhle nokumelana nowoyela okuhle, okuyenza ibe nezinzuzo ezisobala ngaphezu kokudla okunwetshiwe kwe-polystyrene emakethe yokupakisha alahlwayo.
2. Ukushisa okushisayo
Impahla ye-polypropylene enegwebu uhlobo olusha lwezinto ezishisayo zokushisa ezinokumelana nokushisa okuqinile.Ivamise ukumelana nezinga lokushisa elingu -40 kuya ku-110 °C, futhi ingamelana nezinga lokushisa eliphakeme elingu-130 °C ngesikhathi esifushane.
3. Imboni yezimoto
Eminyakeni yamuva nje, ukusetshenziswa kwe-polypropylene enegwebu embonini yezimoto kuye kwanda, okunganciphisa kakhulu isisindo semoto futhi konge ukusetshenziswa kukaphethiloli.
4. Inkambu yokwakha
Izinto zokuvikela ezingangeni manzi, izinto zokugudluza phansi, izinto ezifakwa odongeni zangaphandle
5. I-Electronic Packaging
6. Ukupakishwa kwebhafa
7. Izimpahla Zezemidlalo
8. Amathoyizi
Abakhiqizi abakhulu be-polypropylene enegwebu
Imikhiqizo ye-polypropylene enegwebu inokusebenza okuhle namathemba okufaka isicelo, kodwa ukuthuthukiswa kobuchwepheshe kunzima kakhulu.Okwamanje, ayikho imikhiqizo ehlobene yezimboni e-China.Ubuchwepheshe obuyisisekelo busezandleni ze-JSP kanye ne-KANEKA.
