Extrusion Molding ke Eng?
Extrusion molding, eo hape e tsejoang e le extrusion in plastic processing, e sebelisa khatello ea hydraulic ho qobella thepa ka hlobo, ho theha likarolo tse tsoelang pele tsa libopeho tse fapaneng. Ts'ebetso ena e kenyelletsa ho futhumatsa thepa ha e ntse e sutumelletsoa pele ke screw ka har'a moqomo, e leng se etsang hore ho thehoe li-profiles tse tsoelang pele kapa lihlahisoa tsa halofo. Extrusion molding, thekenoloji ea pele ea ho sebetsa ka polymer, e bile teng lilemong tse 100 tse fetileng hore e be mokhoa o sebetsang hantle haholo, o tsoelang pele, o theko e tlase o sebetsang ka botlalo. Hona joale ke mokhoa o sebelisoang ka ho fetesisa oa ho etsa li-polymer ka lebaka la ho ikamahanya le maemo, litheko tse phahameng tsa tlhahiso, le ho feto-fetoha ha maemo.
Mekhoa ea Motheo ho Extrusion Molding
1. Ho fepa
Lintho tsa polasetiki li tšeloa ka har'a hopper ebe li fetela ka har'a likanale tsa "screw" tlas'a matla a khoheli kapa ka thuso ea sefepi, ho ea fihla hloohong.
2. Ho fetisa
Ha polasetiki e kena ka kanaleng ea screw, e ea pele ka ho potoloha ha screw ka 'ngoe. Sekhahla sa 'nete sa phetisetso se ipapisitse le likhokahano tsa likhohlano tsa polasetiki khahlano le barrel le screw. Khohlano e phahameng ka barrel kapa khohlano e tlase e nang le screw e eketsa motsamao oa pele oa polasetiki.
3. Khatello
Compression ke ea bohlokoa ho bopeng extrusion. Plastiki ke mokhanni ea futsanehileng oa mocheso, 'me likheo leha e le life pakeng tsa likaroloana li ka sitisa ho fetisoa ha mocheso, ho ama litekanyetso tsa ho qhibiliha. Ho hatella ho thusa ho leleka likhase ho tsoa linthong tse bonahalang, ho thibela mefokolo, le ho netefatsa hore sehlahisoa se tsitsitse ka ho boloka khatello e phahameng ea tsamaiso.
4. Ho qhibiliha
Ka khatello e ntseng e phahama, li-contact tsa polasetiki tse tiileng tse tsamaeang le ho itlotsa khahlanong le lerako le futhumetseng la moqomo, ho etsa filimi e tšesaane e qhibilihang. Filimi ena e hlajoa ke screw ha e ntse e tsamaea, e bokellana ka pel'a lifofane tse fofang ebe e etsa letamo la ho qhibiliha.
5. Ho kopanya
Tlas'a khatello e phahameng, thepa e tiileng e kopantsoe ka har'a polaka e teteaneng. Ho kopanya ho etsahala feela lipakeng tsa masela a qhibilihileng, eseng ka har'a polaka e tiileng.
6. Ho khathatsa
Ho kenya moea ho bohlokoa ho tlosa likhase le mouoane o hlahisoang nakong ea ts'ebetso ea extrusion. Ho kenya moea ka nepo ho netefatsa boleng ba sehlahisoa sa ho qetela ka ho thibela likheo le mefokolo.
Melemo ea Extrusion Molding
Thepa e Bonolo e nang le Matsete a Tlase: Mochini oa ho bopa extrusion o otlolohile ebile o na le chelete e ngata.
Tlhahiso e Tsoelang Pele ka Bokhabane bo Phahameng: Extrusion e lumella tlhahiso e tsoelang pele, e ntlafatsang katleho.
Boemo bo Phahameng ba Boiketsetso: Boiketsetso bo fokotsa matla a mosebetsi mme bo eketsa ho nepahala.
Ts'ebetso e Bonolo le Taolo ea Ts'ebetso: Ts'ebetso e bonolo ho basebelisi ebile ea laoleha.
Lihlahisoa tse sa tšoaneng le tsa boleng bo phahameng: Ts'ebetso ea extrusion e hlahisa lihlahisoa tse tsitsitseng le tse teteaneng.
Tšebelisano e pharaletseng ea lintho tse bonahalang: Boholo ba thermoplastic le lisebelisoa tse ling tsa thermosetting li ka sebelisoa.
Lisebelisoa tse fapaneng: Ho bopa ha Extrusion ho loketse lihlahisoa tse fapaneng, ho etsa hore e be ts'ebetso e mengata.
Compact Production Lines: Ts'ebetso e hloka sebaka se fokolang mme e boloka tikoloho ea tlhahiso e hloekileng.
Lintlha tsa bohlokoa ho Extrusion Molding
Litlhahlobo tsa ho qala: Lekola barrel, hopper, le li-fasteners, ho netefatsa hore likarolo tsohle li bolokehile. Tlotsa ha ho hlokahala 'me u hloekise lisebelisoa.
Ho qala ka lebelo le tlase: Qala ka ho sebelisa screw ka lebelo le tlase, ho beha leihlo bakeng sa liphoso leha e le life tsa tšebetso ea enjene kapa molumo.
Liteko tse Khutšoanyane tsa ho se be le moroalo: Teko ea "Limit screw" e nka metsotso e 30 pele e hokela hlobo ea tlhahiso, e tlotsa liboutu tsa hlobo hore li tlosoe habonolo.
Ho fepa butle butle: Qala ka lebelo le tlase la screw mme u fepe thepa ka ho lekana, u shebelle liphetoho life kapa life tsa motlakase oa motlakase.
Tlhokomelo ea Mocheso: Kamehla hlahloba mocheso oa ho beha, ho etsa bonnete ba hore ha o kopane ka ho toba le likarolo tse tsamaeang nakong ea ts'ebetso.
Litharollo tsa Surface Roughness: Eketsa mocheso, lokisa lebelo la sekoti, fetola li-filters, 'me u sebelise lisebelisoa tse omisang tse loketseng ho thibela bofokoli bo holim'a metsi.
Thibelo ea ho Eketsa: Fokotsa tšebeliso ea mafura, ntlafatsa thepa ea thepa, kapa sebelisa litlolo tsa Teflon ho fokotsa sekhahla.
Ho Boloka Sephetho se Tsitsitseng: Lokisa ho feto-fetoha ha maemo ka ho lokisa maemo, ho sebelisa libopeho tse fapaneng tsa screw, le ho laola phapang ea mocheso ho netefatsa extrusion e tsitsitseng.
Lisebelisoa tsa Extrusion Molding
Litlaleho tsa polasetiki tsa extrusion li loketse ho hlahisa liphaephe, litlaleho tsa mamati, likarolo tsa likoloi, le tse ling.
1. Liphaephe le Tubing
Extrusion e atisa ho sebelisoa ho hlahisa liphaephe tsa polasetiki le li-tubing ho tloha thepa e kang PVC le thermoplastics tse ling.
2. Mohaho oa Mohala
Li-thermoplastics tse ngata ke li-insulators tse ntle haholo, tse etsang hore li tšoanelehe bakeng sa ho kenya terata e tsoang ka ntle ho terata le thapo le sheathing, ho kenyelletsa le likhetho tsa fluoropolymer.
3. Menyako le Lifensetere Profiles
PVC ke thepa e tsebahalang bakeng sa ho hlahisa liforeimi tse tsoelang pele tsa mamati le lifensetere, tse loketseng lits'ebetso tsa lapeng.
4. Lifofu
Thermoplastics e ka fetisoa ho etsa li-slats tse tšoanang tsa lifofu, hangata li sebelisa polystyrene bakeng sa ponahalo ea lehong la bohata.
5. Ho hlobola boemo ba leholimo
Hangata lihlahisoa tsa ho hlobolisa rabara tsa leholimo li ntšoa, 'me li fana ka tharollo e sebetsang ea ho tiisa lits'ebetso tse fapaneng.
6. Windshield Wipers le Squeegees
Li-wipers tsa likoloi tsa likoloi le li-blade squeegee blades li atisa ho etsoa ka thepa ea rabara e entsoeng ka extruded joaloka EPDM.
Ho feto-fetoha ha maemo le bokhoni ba ho bopa extrusion ho etsa hore e be motheo oa indasteri ea tlhahiso ea polasetiki, e nang le mefuta e mengata ea likopo le melemo e tsamaisang tšebeliso ea eona e pharaletseng.
