Ungasilawula kanjani isikhathi sokuqala kwesihlabathi se-furin resin ngaphansi kwendawo yokushisa ephansi

Ikakhulukazi wafunda ubudlelwano phakathi kwesikhathi esisebenzisekayo sika-furan resin sand, isikhathi sokukhishwa kwesikhunta namandla ngaphansi kwezinga lokushisa eliphansi, futhi kunqume ukushisa kwesihlabathi okufanelekile ne-resin elapha i-ejenti isilinganiso sokuqondisa ukukhiqizwa komhlangano.

Background

Isihlabathi seFuran resin no-bake sihlangene futhi sinzima, kulula ukusilawula, futhi sinokunemba okuphezulu kokuphosa. Ngakho-ke, inqubo yamanje yenhlabathi engabhakwa isetshenziselwe ukusakaza izinsimbi ezahlukahlukene zensimbi, njengamathuluzi emishini adingekayo ekwenzeni imishini nemishini yegesi esetshenziselwa ukwakha umkhumbi. Futhi okunye ukusakazwa kwensimbi kungakhiqizwa ngenqubo yesihlabathi se-resin esiqinile. Kulezi zinsuku, ukuthuthukiswa okusheshayo kokulawulwa kwe-computer automation kusheshise ukuthuthukiswa nokusetshenziswa kobuchwepheshe be-resin sand sand.

Kodwa-ke, isihlabathi se-furan resin sinamaphutha aso. Isikhathi esisebenzisekayo, isikhathi sokukhishwa kwesikhunta namandla okugcina sithinteka kakhulu ngoshintsho kumazinga okushisa nomswakama, okungadala kalula ukungazinzi komkhiqizo futhi kuphazamise ukukhiqizwa kweworkshop. Ngokuya ngezinto zokulingisa ezisetshenziswa yinkampani, leli phepha lifunda ijika elelaphayo le-furan resin ne-benzenesulfonic acid elapha i-ejenti ngezilinganiso ezahlukahlukene ngaphansi kwezinga lokushisa eliphansi, linquma isilinganiso esihle kakhulu, futhi lihlola ukuthambekela kokuqina kwesikhunta sokhuni nensimbi yesikhunta sensimbi ngalesi sisekelo. , Beka phambili indlela yokusheshisa ukukhishwa kwesikhunta ukuqina ukukhiqiza ukwenziwa kweworkshop.

Ucwaningo lokuhlola

Lo mbhalo usebenzisa i-furan resin, i-benzene sulfonic acid ekwelapheni i-ejenti nesihlabathi se-silica esivuselelwe esisetshenziswe yinkampani esizeni njengezinto zokuhlola

Izinsimbi: ibhalansi ye-elekthronikhi, isixubeki esizenzakalelayo, isivivinyo sokucindezelwa, imitha lokushisa nomswakama, i-thermometer, isitophuwashi. Amazinga we-ambient yi-5 ℃, umswakama omkhulu yi-30%, kanti izinga lokushisa lesihlabathi liyi-15 ℃. Kala isihlabathi esingu-1000g ngebhalansi kagesi. Inani le-resin kwalokho lingu-0.8% no-1.0% wesisindo sesihlabathi. Umenzeli ophulukisayo ungezwe ku-30%, 35%, 40%, 45%, 50% wesisindo se-resin, ngokulandelana. Test Orthogonal kwenza φ40mm × 40mm Molding isihlabathi test block. Ngasikhathi sinye, rekhoda isikhathi sokusebenza, isikhathi sokukhishwa kwesikhunta namandla we-24h wokucindezela.

Ngokuya ngezidingo zokukhiqizwa esizeni, kunezidingo ezilandelayo zokubumba isihlabathi:

• Isihlabathi sokubumba kufanele sigcine amandla athile wokugcina (ukusakazwa okuncane ≥2.0MPa, ukusakazwa okukhulu ≥3.0MPa) ukunciphisa ukwehliswa okuyisisekelo nokuvimbela ukufakwa kwesihlabathi ekuphonsweni.
• Isikhathi sokusebenza esidingekayo kufanele siqinisekiswe ukwenza lula ukubekwa kwensimbi eyinhloko, i-iron ebandayo nokusebenza okuhlangene.
• Ukuze kuqinisekiswe ukukhiqizwa kwesayithi okushelelayo, isikhathi sokukhishwa esiyisisekelo kufanele sibe sifushane ngangokunokwenzeka ukuthuthukisa ukusebenza kahle kokukhiqiza.
• Endabeni yokuhlangabezana nezidingo zokukhiqiza, inani le-binder elingeziwe kufanele libe liphansi ngangokunokwenzeka, elingagcini nje ngokugcina izindleko, kepha futhi lehlisa negesi eyenziwe ngomlilo we-organic binder ngesikhathi sokuthela, ithuthukise ikhwalithi yokuphosa, futhi ivikele imvelo.

Ngokuya ngezici ezingenhla, isilinganiso esihle kakhulu sezinto ezingamanzi esihlabathi esibuyiselwe ngomshini yi-resin 1.0% (ukubalwa kwesisindo sesihlabathi), i-ejenti elapha i-30% (i-accounting ye-resin); isilinganiso esihle kunazo zonke sezinto eziwuketshezi sesihlabathi esibuyisiwe esishisayo yi-resin 1.0% (ukubalwa kwesisindo sesihlabathi)), i-ejenti elapha i-45% (ukubalwa kwe-resin).

Ngaphezu kwalokho, kucatshangelwa umehluko ngesikhathi sokukhishwa phakathi kwesikhunta sokhuni kanye nesikhunta sensimbi esikhiqizwe esizeni, ngesisekelo sovivinyo olungenhla, ibhokisi lomgogodla wokhuni nebhokisi lensimbi eyinsimbi kwasetshenziswa ukulungiselela amasampula, namandla acindezelayo kukalwe njalo ngo-1h, futhi kwaqoshwa umkhuba wokushintsha kwamandla we-6h no-24h wokuqala. Amandla okugcina

Futhi ngaphansi kwemvelo ka-5 ℃, lapho i-resin ne-ejenti elaphayo ingezwa engxenyeni ethile:

• Ukwenziwa kwesikhunta sokhuni kuthatha cishe amahora amabili kuya kwamathathu ukukhipha isikhunta kusikhunta (2MPa), bese isikhunta siqina ukuthola amandla anele ngaphandle kokukhubazeka; isikhunta sensimbi sithatha amahora ama-3 ukukhipha, futhi ingxenye yangaphakathi ingakhishwa kusenesikhathi. Kuqiniswe ngokuphelele, ukususwa kwe-extrusion kuzokwenzeka, futhi amandla wokugcina ngokufanayo ayafana, cishe nge-1.5MPa.
• Ukukhulisa nje inani le-asidi ye-ejenti elaphayo akukwazi ukwandisa kakhulu ijubane lokuqina futhi kunciphise isikhathi sokukhishwa kwesikhunta.

Ngokwalo mkhuba wokwenza lukhuni, ukukhiqizwa esizeni kungakuhlelela ngokunengqondo ukukhiqizwa ngokusho kwesikhathi sokuqala sokuqala samamodeli ukugwema ukuqala kwesikhunta ngaphambi kwesikhathi. Amandla anele okuqinisa isihlabathi emgodini azobangela ukusonteka nokuqhekeka okuyisisekelo. Umnyombo wemodeli unamandla aqinile futhi uhlanganiswe ngokuqinile kusikhunta. , Kunzima ukuqala isikhunta, okuholele ekutheni ikhwalithi engalungile yomhlaba nokubambezeleka kokukhiqizwa kusayithi.

Isiphetho

Esimweni sokushisa okuphansi, lapho i-furan resin ne-benzene sulfonic acid curing agent isetshenziswa njengezihlanganisi, kuneziphetho ezintathu zokuhlola ngokulandelayo:

• Okusemandleni uketshezi lwesihlabathi esibuyiselwe ngomshini i-resin 1.0% (ukubalwa kwesisindo sesihlabathi), i-ejenti elapha i-30% (ukubalwa kwe-resin); okungcono kakhulu okokufaka oketshezi kwesihlabathi esibuyisiwe esishisayo yi-resin 1.0% (ukubalwa kwesisindo sesihlabathi), kuphulukisa i-Agent 45% (ukubalwa kwe-resin).
• Ezinye izimo zihlala zingashintshiwe. Ukukhulisa nje i-asidi ephelele yomenzeli ophulukisayo akukwazi ukunciphisa kakhulu isikhathi sokukhishwa kwesikhunta. Ukuphendula kwangaphakathi nokwenza lukhuni kungasheshiswa ngokwandisa izinga lokushisa lemodeli, izinga lokushisa kwensimbi ebandayo nokusetshenziswa kwamathuluzi.
• Lapho izimo zifana, isikhathi sokukhishwa kwesikhunta sokhuni sincishiswe kakhulu uma kuqhathaniswa nesikhunta sensimbi, kanti esokuqala siyi-1/2 yesibili.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Ungasilawula kanjani isikhathi sokuqala kwesihlabathi se-furin resin ngaphansi kwendawo yokushisa ephansi
