Yiziphi izinhlobo zokusakaza ezilungele ukukhiqizwa kwesihlabathi se-phenolic resin nesihlabathi se-furan resin?

1. Izici ze-phenolic resin sand kanye nebanga elifanelekile lokukhiqiza

a. Inkomba yokusebenza ejwayelekile ye-Phenolic Resin Sand: UPhenolic Resin Sand unamandla okuvikelwa okuhle futhi ngokuvamile angasetshenziselwa isikhathi eside ngaphansi kwama-200 ℃. Ezinye izihlabathi eziguquliwe ze-phenolic resin zingagcina ukusebenza kwazo emazingeni okushisa aphezulu. Emazingeni okushisa aphezulu, i-phenolic resin ikhiqiza amazinga aphezulu ekhabhoni enezinsika, okuzuzisa ukugcina ukuqina kokuqina kwesihlabathi futhi kubenze bakwazi ukubekezelela ukuguguleka kwensimbi ephakeme kakhulu ngesikhathi sokushisa. Ukuphefumula kwesihlabathi se-phenolic resin kuthonywa yizinto ezahlukahlukene. Lapho usebenzisa isitayela esiphezulu, ukuphefumula kwaso kuvame ukulawulwa phakathi kuka-100-140, ofanele kakhulu. Okokukhishwa okuncane noma izimo ezincane ezinezidingo ezisezingeni eliphakeme kakhulu zekhwalithi kanye nezidingo eziphansi zegesi eziphansi, ukuvumela kungaba cishe ngo-80-120; Ukuphonswa okukhulu noma ama-castings anezakhi eziyinkimbinkimbi kanye nezidingo eziphakeme zokuqeda igesi, kungahle kudingeke ukulawula ukuvumela ngo-120-180 noma ngaphezulu. Izinga lokusebenzisana lingabonisa ukoma, okumanzi, nokugeleza kwesihlabathi sokubumba. Ngokuvamile, lapho isilinganiso sokuhlangana kumswakama siphakathi kuka-10-12, kukhombisa ukuthi ukoma nokuma komhlaba kwesihlabathi se-phenolic resin kusesimweni esihle. Uma isilinganiso singaphansi kwe-10, okuqukethwe kobumba kwesihlabathi sokubumba kuphakeme futhi ubunzima bumpofu; Uma isilinganiso sikhulu kune-12, okuqukethwe kodaka kwesihlabathi sokubumba kungahle kube phansi, futhi ukuvumela kungenzeka kube phezulu, okungadala kalula iziphambeko zesihlabathi ekusakazeni.

b. I-Phenolic Resin sand ilungele ukukhiqiza izinhlobo ezahlukahlukene zokukhokhiswa, ikakhulukazi kufaka phakathi okulandelayo: Izingxenye zensimbi yensimbi, izingxenye zemishini ye-axle, njll. I-phospholic resin, ezingavimba amaphutha anjenge-porings futhi aqinisekise ngempumelelo ikhwalithi ye I-Alloy Steel Castings. I-High Manganese Steel Castings: njengokuthumela ngaphandle ukuthumela ama-mangesen steel castings, njll. I-Co ₂ ₂ Hardgenned Alkaliline Resin Sand isebenza kahle kakhulu inqubo. Lapho isetshenziswa ekukhiqizweni kwe-High Manganese Steel Castings, kungenza ingaphezulu kwama-castings bushelelezi, ngama-pores ambalwa, futhi akukho ukuqhekeka okubandayo, ukuqhekeka okushisayo, noma i-carbonization punomena. Cast Iron Ductile Iron CrankShaft: Njengesigaba esikhulu se-rouctile iron crankshafts ngo-6160, 6200, we-WD615 Series Diesel Enjini. Isihlabathi se-Alkaline Shenolic Phenolic Shenolic Resin singaxazulula inkinga ye-spherhailization yasendaweni ekukhiqizweni kwe-Ductile Iron CrankShaft ngokusebenzisa isihlabathi se-furan se-furan Izindawo ezingezinhle zensimbi kanye nezingxenye ze-cast aluminium: Ezinye izingxenye eziyinkimbinkimbi ze-aluminium ezihlelekile nazo zingakhiqizwa kusetshenziswa isihlabathi se-phenolic resin. Embonini, amanye amabhizinisi athole izinzuzo ezinhle zobuchwepheshe, ezomnotho kanye nezemvelo ngokusebenzisa u-Ester ukhuni u-Alkali Penolic Resin Sange Technology ukukhiqiza i-aluminium leastrings ngomugqa ofanayo wokukhiqiza. Ngaphezu kwalokho, noma ngabe izingxenye zensimbi eziphakeme eziphezulu ezikhiqizwe ngamabheji amancane, noma izingxenye ze-aluminium, izingxenye ze-aluminium, njll. Isihlabathi esikhiqizwe ngamabhathi, i-phenolic resin sand ingadlala izinzuzo zayo futhi izinhlobo zayo zokukhiqiza. Ngasikhathi sinye, kubuchwepheshe be-SAND MOL NDAWO TRIPET Technology, i-Phenolic resin eguquliwe isetshenziswa kabanzi njenge-binder yokuthuthukiswa kwamasampula we-single purt yensimbi, i-iron iron, kanye nokukhiqizwa kwemikhiqizo ephonsanayo. Inezimpawu zesivinini sokuphendula esisheshayo, umjikelezo omfushane, nokuguquguquka okuphezulu.

2. Izici zesihlabathi se-furan resin kanye nohlu olufanele lokukhiqiza

a. I-Uhlu Lokulawula Lenkomba Ehlobene Nobulungiswa yeFuran Resin Amanye ama-remins we-furan aguqulwe ngokukhethekile, anjenge-XLZ Furan Resin, angakwazi ukumelana no-180 ℃, kanye ne-Huibo XLZ600 Furan Resin Adhesive asakwazi ukugcina amandla aphezulu endaweni engama-230 ℃. Kukhona futhi ama-fulan ahlala njenge-Sugar Alcohol Remins, engamelana namazinga okushisa angama-400 ℃ -500 ℃, futhi izinto zazo ze-carbonised zingamelana namazinga okushisa amakhulu kune-2100 ℃. Ukuphefumula: Lapho usebenzisa isitayela esiphezulu, ukuphefumula kungabhekisela ku-100-140; Uma kuyinqubo ejwayelekile yesitayela, ukuphefumula kungaphakathi kwebanga le-300-500. Ukuphefumula kwezindleko ezincane zingaba phakathi kuka-300-400, kuyilapho izinkambo ezinkulu noma izinqolobane ezinezinto eziyinkimbinkimbi, ukuphefumula kungadinga ukulawulwa phakathi kuka-400-500 noma ngaphezulu. Izinga lokusebenzisana: Izinga lokuhlangana kwesihlabathi se-furan resin ngokuvamile asilawulwa ngokuqinile ngaphakathi kobubanzi obuhleliwe, imvamisa cishe ngo-40% -60%. Kodwa-ke, ekukhiqizweni kwangempela, ukulungiswa kudinga ukwenziwa ngokuya ngezinto ezifana nezimpawu zesihlabathi esiluhlaza, inani le-resin ne-ejenti yokuvuka. Ngaphezu kwalokho, amandla ashubile e-furan resin hlaba amabhlokhi angu-8 ngokuvamile adinga ukuthi amandla okuqala (amandla ashubile ayi-1) kufanele alawulwe phakathi kwe-0.1mpa-0.4MPA, namandla okugcina) kufanele alawulwe phakathi kuka-0.6mpa-0.9MPA. Uhla lokushisa olufanele lokuxuba kwesihlabathi lungu-20 ℃ -30 ℃, kanye nenani le-ejenti yokwelapha elingeziwe ngokuvamile 30% -60% we-resin mass.

b. Ingabe isihlabathi se-furan resin silungele ukukhiqiza izinhlobo ezahlukahlukene zokukhokhiswa? Izingxenye ze-Iron: ezinjengezingxenye zensimbi ephakeme, izingxenye zensimbi ezimpunga, njll. I-Furan Resin Isihlabathi inobunzima obuhle, ingenza ubuso bube bushelelezi, ukunemba okuphezulu, futhi kuqukethe ama-nitrogen, isibabule nezinye izinto. Ingahlangabezana nezidingo zenqubo ekwenziweni kwezingxenye zensimbi futhi zinezindleko eziphansi. Ama-Steel Castings: Kwamanye ama-castings ensimbi adinga amandla aphezulu nokunemba, njengamagiya kanye nemishini yemishini emikhulu, isihlabathi se-furan resin kunganikeza amandla amahle nokuqiniseka okuphezulu ngenkathi kuqinisekiswa ukwakheka kwama-castings. Kodwa-ke, ngenxa yokuqukethwe kwe-nitrogen kanye nesibabule esihlabathini se-furan resin, amaphutha anjenge-porolity angenzeka ezingxenyeni zensimbi. Ngokuvamile kunconyelwa ukusebenzisa i-nitrogen free noma ephansi ye-nitrogen furan resin (ngokuqukethwe kwe-nitrogen okungaphansi kwe-1.5%) ukukhiqiza izingxenye zensimbi. Ama-castings wensimbi angenzi lutho: njenge-aluminium alloys, ama-alloys ethusi, nezinye izindlela ezingezona zensimbi ezingezinhle. Isihlabathi se-furan resin sinokukhula okuhle futhi kulula ukuhlanza umnyombo, okuzuzisa ukuthuthukisa indawo kanye nekhwalithi yangaphakathi yokukhokhwa kwensimbi engeyona eyonakalisiwe. Izakhi eziyinkimbinkimbi zezakhiwo: Inqubo ye-Furman Resin Sand ingakhiqiza ama-castings anezimo eziyinkimbinkimbi, njengama-cylinder ezinjini ezinjini zezimoto, amakhanda amasilinda, nezinye izingxenye ngezakhiwo zangaphakathi ze-cavity yangaphakathi. Kungaphindaphinda ngokunembile ukwakheka okuyinkimbinkimbi ukuqinisekisa ukunemba okubucayi kanye nekhwalithi ephezulu yentela. Ukukhishwa okunembile: Ukuphonsa ngokunemba, isihlabathi se-furan resin singasetjenziselwa i-Shell casting noma isikhunta sesihlabathi sokuphrinta esingu-3D, silungele ukukhiqizwa kwezinto ezinobunzima bokunemba, isikhunta, njll. Lokho kudinga ubulukhuni obukhulu obukhulu nobunzima obukhulu. Isihlabathi se-furan resin silungele ukukhiqizwa kwe-batch encane kanye nokukhiqizwa komugqa omkhulu womhlangano.
