E lahlehetsoe ke foam

 Kakaretso ea 1.1

Ka 1958, HF Shroyer o ile a qapa theknoloji ea ho etsa litšepe ka mefuta e mengata ea polasetiki ea foam mme a fumana tokelo ea molao. Moetso o neng o sebelisoa qalong o ne o entsoe ka boto ea polystyrene (EPS) mme o entsoe ka lehlabathe le nang le binder. Likhamphani tsa Jeremane Grunzweig le Harrtmann ba rekile tokelo ena ea molao mme ba e ntlafatsa le ho e sebelisa. Mahlale a morao-rao a sebelisang lehlabathe le ommeng le senang binder ho hlahisa li-castings hamorao a fuoa patente ke TRSmith ka 1964. Pele ho 1980, ts'ebeliso ea ts'ebetso ea lehlabathe le ommeng e se nang binder e ne e tlameha ho amoheloa ke Full Mold Process (Inc). Kamora moo, patent e ne e sa sebetse.

Mokhoa o tloaelehileng le o sebetsang ka ho fetesisa ke ho beha mofuta o koahetsoeng ka lintho tse haelloang ka lebokoseng la lehlabathe, o tlatse mohlala ka lehlabathe le ommeng ka thata, ebe o tšela tšepe ea mokelikeli ho nkela mofuta oa foam. Ts'ebetso ena ea ho betsa e bitsoa: ho lahla foam (EPC), ho betsa hlobo ea khase le ho betsa hlobo e tiileng, jj. Komiti e Lahlehileng ea foam e lahliloeng ea American Foundry Association e amohetse "ho lahla foam" joalo ka lebitso la ts'ebetso.

Lahla foam Tsamaiso phallo ea ho lahla foam e lahlehileng e tjena:

1) Pele ho phoka
Tlhahiso ea Model ke mohato oa pele oa ts'ebetso e lahlehileng ea foam. Bakeng sa li-castings tse rarahaneng joalo ka lihlooho tsa silindara, mefuta e mengata ea foam e hloka ho etsoa ka thoko, ebe e manamisoa ka har'a mofuta o akaretsang. Moetso o mong le o mong oa block o hloka sete ea hlobo bakeng sa tlhahiso. Ntle le moo, ho ka hlokahala seteishene sa hlobo ho ts'ebetso ea sekhomaretsi ho boloka boemo bo nepahetseng ba boloko ka bong. Ts'ebetso ea sebopeho sa mohlala e arotsoe ka mehato e 'meli. Mohato oa pele ke ho Lifaha tsa polystyrene li eketsoa pele ho palo e loketseng, e atisang ho etsoa ka ho futhumatsa ka potlako ka mouoane. Sethala sena se bitsoa pele ho katoloso.

2) Model eaba ba etsa
Lifaha tse seng li atolositsoe li lokela ho tsitsisoa pele, ebe li romelloa ho mochini oa mochini o hlophisitsoeng, ebe li fepeloa ka lesoba la phepelo. Kamora hore lesapo la hlobo le tlale lifaha tse seng li atolositsoe, ho hlahisoa mouoane ho nolofatsa lifaha. Keketseho, ho tlatsa likheo tsohle le ho ikamahanya le 'mele o le mong, ka hona ho phethela tšebetso ea tlhahiso ea mofuta oa foam, mothati ona o bitsoa sebopeho sa autoclave.

Kamora ho bōpa, hlobo e folisoa ke phallo e kholo ea metsi kahare e pholileng ea metsi ea hlobo, ebe hlobo ea buleloa ho ntša hlobo. Nakong ena, mocheso oa hlobo o eketseha mme matla a tlase. Ka hona, tlhokomelo e tlameha ho nkuoa nakong ea ho heletsoa le ho bolokoa ho thibela ho fetoha le tšenyo.

3) Motsoako oa sehlopha sa mohlala
Pele mohlala o sebelisoa, o tlameha ho bolokoa nako e nepahetseng ho o etsa o holileng le o tsitsitseng. Nako e tloaelehileng ea polokelo ea mohlala e fihla matsatsing a 30. Bakeng sa mohlala o entsoeng ka hlobo e ikhethileng e hloka feela ho bolokoa lihora tse 2. Ka mor'a hore mohlala o hōle le ho tsitsa, o ka aroloa likarolo tse peli. Mefuta ea li-block e hokahantsoe hammoho.
Gluing ea mofuta oa block e etsoa ka mochini o iketsang oa ho khomarela o sebelisa sekhomaretsi se chesang. Manonyeletso a bokaholimo bo hoketsoeng a lokela ho tiisoa ka thata ho fokotsa monyetla oa ho baka litšitiso.

4) Model lesihla ina barbotage
Bakeng sa ho hlahisa li-castings tse ngata ka lebokoseng, ka linako tse ling mefuta e mengata e manamisoa ka lihlopha, 'me lihlopha tsa mohlala li qoelitsoe ka pente e khabisitsoeng, ebe li omisoa ka ontong ea moea o ka bang 30-60C (86-140F) bakeng sa 2 ho isa ho 3 Kamora moo. lihora tse ommeng, kenya lesihla la mohlala ka lebokoseng la lehlabathe, le tlatse ka lehlabathe le ommeng ebe o thothomela ka thata. Likoti tsohle tse kahare le lehlabathe le ka ntle le ommeng la sehlopha sa mohlala li tlameha ho koaheloa le ho tšehetsoa.

5) Ho tšela
Kamora hore lesihla la mohlala le tlatsitsoe ka lehlabathe le ommeng ka lebokoseng la lehlabathe, hlobo e ka tšeloa. Kamora hore tšepe e qhibilihisitsoeng e tšeloe ka hlobo (mocheso oa ho lahla o ka ba 760C / 1400F bakeng sa aluminium e entsoeng, 'me e ka ba ka 1425C / 2600F bakeng sa tšepe ea tšepe), mofuta ona oa foforeha. Tshepe e nkeloa sebaka ho etsa samente. Setšoantšo sa 1 ke setšoantšo sa lebokose la lehlabathe le ho tšollela ts'ebetso ea foam e lahlehileng.

Ka lahlehileng bubble thulaganyou e foromeletsoeng, lebelo tšollela ke mahlonoko tseo ho feta ho lahla ea setso sekoti. Haeba ts'ebetso ea ho tšela e sitisoa, hlobo ea lehlabathe e ka putlama ebe e baka litšila. Ka hona, molemong oa ho fokotsa phapang lipakeng tsa tšollo ka 'ngoe, ho molemo ho sebelisa mochini o tšollang o iketsang.

 Setšoantšo sa 1 Setšoantšo sa moralo oa lebokose la lehlabathe le ho tšollela ts'ebetso ea foam e lahlehileng
6) Ho hloekisa lehlabathe le oang
Kamora ho tšela, ho lahla hoa tiea le ho phola ka lebokoseng la lehlabathe, ebe ho oa lehlabatheng. Lehlabathe le oelang la ho betsa le bonolo haholo, 'me litšiea li oela lehlabatheng le ommeng le ommeng ha lebokose la lehlabathe le phethoha. Kamora moo, castings e ikarola ka bo eona, ea hloekisoa, ea hlahlojoa le ho tsamaisoa ka lebokoseng.

Lehlabathe le ommeng le ka sebelisoa bocha kamora ho pholisa, 'me lits'ebetso tse ling tsa tlatsetso ha li sebelisoe hangata. Lisebelisoa tsa tšepe li ka hlakoloa ebe li sebelisoa tlhahiso.

1.2 Melemo ea ts'ebetso e lahlehileng ea foam

Ts'ebetso e lahlehileng ea foam e na le menyetla lintlheng tse tharo tse kholo: theknoloji, moruo le ts'ireletso ea tikoloho.

1.2.1 Lintlha tsa tekheniki

1) Bolokolohi bo eketsehileng ba moralo oa mohlala
Ts'ebetso e ncha e kanna ea etsoa ka setaele, 'me ho ka etsahala hore o kenye mesebetsi e meng ea tlatsetso ho mohlala ho tloha sethaleng sa pele. Mohlala, preheater ea disele e na le karolo e ikhethang e sebetsang, e ka etsoang ke ts'ebetso e lahlehileng ea foam e lahliloeng ho fapana le mokhoa oa setso oa ho betsa.
 
2) Tlosa mokokotlo oa lehlabathe o sebelisitsoeng ho hlahiseng castings

3) Li-castings tse ngata li ka fepa ntle le riser

4) Ntlafatsa ho nepahala ha ho lahla
E ka fumana sebopeho le sebopeho se rarahaneng, 'me e ka hlahisa makhetlo a mangata ka mokhoa o nepahetseng o phetoang ka 100%, mme ho kheloha ha botenya ba castings ho ka laoloa lipakeng tsa -0.15 ~ + 0.15mm.

5) Ha ho na khanya holim'a sefahleho se kopaneng sa mohlala

6) E na le monyetla oa ho fokotsa boima ba "castings" ka "1/3"

7) Fokotsa kabelo ea machining
Chelete ea machining e ka fokotsoa, ​​'me likarolo tse ling li kanna tsa se sebetsoe. Sena se fokotsa matsete haholo ho lisebelisoa tsa mechini le mochini (mohlala, matsete a ka fokotsoa ka halofo bakeng sa maemo a fapaneng).

8) Ha ho bapisoa le ho lahla setso cavity, le dipeeletso hlobo e fokotsehile.
 
9) Felisa ka botlalo ts'ebetso ea moetlo ea lehlabathe le oelang le khubung

1.2.2 Likarolo tsa moruo

1) E ka hlahisa castings e rarahaneng ka kakaretso
Ho amohela moralo o mocha oa tšebetso, mofuta oa block o ka manamisoa ho etsa mofuta oa kakaretso mme o kenngoe karolong e rarahaneng ea bohlokoa. Ha e bapisoa le likarolo tsa pele tsa kopano tse lahlang (tse kang preheater ea dizeli), e ka una molemo ho tloha makhetlo a 1 ho isa ho a 10.

2) Fokotsa basebetsi ba likopanong
Ho theha feme e lahlehileng ea foam, palo ea bahiruoa e tlase ho feta ea feme ea setso, ka hona ntlha ena e lokela ho tsotelloa.

3) tenyetsehang foromeletsoeng thulaganyou e
Ho feto-fetoha ha mokhoa oa ho betsa ho bohlokoa haholo, hobane ts'ebetso e ncha e ka hlahisa palo e kholo ea li-castings tse tšoanang kapa tse fapaneng ka botlolo, ka hona sistimi ea gating e fetoha haholo. Ka bokhutšoanyane, re ka re monyetla o mong le o mong o tsamaellana le lithahasello tsa moruo, ha o ntse o ntlafatsa maemo a ho sebetsa.

1.2.3 Ts'ireletso ea tikoloho

Polystyrene le PMMA li hlahisa carbon monoxide, carbon dioxide, metsi le likhase tse ling tsa hydrocarbon ha li chesoa, 'me litaba tsa eona li tlase ho feta maemo a lumelloang Europe. Lehlabathe le ommeng le ka sebelisa lehlabathe la silika ea tlhaho, e ka sebelisoang hape ka 100% ebile ha e na binder. Pente e sebelisitsoeng mohlaleng ona e entsoe ka binder le lisebelisoa tse ling tse thusang tse ekelitsoeng metsing, tse sa bake tšilafalo.

Ka kopo boloka mohloli le aterese ea sengoloa sena hore se hatisoe hape:E lahlehetsoe ke foam
