Selelekela: Mathata a Tsoelang Pele a Lisebelisoa tsa PA/GF

Glass fiber reinforced polyamides (PA/GF) ke lejoe la motheo tlhahisong ea sejoale-joale ka lebaka la matla a eona a ikhethang a mochini, ho hanyetsa mocheso, le botsitso ba sebopeho. Ho tloha ho likarolo tsa likoloi le lisebelisoa tsa elektronike tsa bareki ho ea mehahong ea sefofane le mechine ea indasteri, thepa ea PA/GF e sebelisoa haholo lits'ebetsong tse sebetsang hantle tse hlokang ho tšoarella, ho nepahala le ho tšepahala.

Leha ho na le melemo ena, thepa ea PA/GF e hlahisa mathata a sa khaotseng a ka senyang katleho ea tlhahiso, boleng ba sehlahisoa le ts'ebetso ea ts'ebeliso ea ho qetela. Lintlha tse tloaelehileng tsa bohloko li kenyelletsa warpage, phallo e fokolang ea ho qhibiliha, ho roala lisebelisoa, le ho pepeseha ha fiber fiber (likhoele tse phaphametseng). Litaba tsena li eketsa litefiso tsa lichelete, li phahamisa litšenyehelo tsa tlhahiso, 'me li batla hore ho etsoe mosebetsi o eketsehileng - liphephetso tse atisang ho ama R&D, tlhahiso le lihlopha tsa ho reka thepa.

Ho utloisisa le ho rarolla mathata ana ho bohlokoa ho bahlahisi ba ikemiselitseng ho eketsa bokhoni ba thepa ea PA/GF ha ba ntse ba boloka ts'ebetso e sebetsang hantle le ho fihlela litekanyetso tse thata tsa boleng.

Ntlha ea Bohloko ea 1: Ts'ebetso e rarahaneng le e thata ho laola

Warpage le Deformation

Lisebelisoa tsa PA / GF li na le anisotropic haholo ka lebaka la ho shebana le likhoele tsa khalase. Nakong ea ho pholisa, shrinkage e sa lekanang hangata e baka warpage ka likarolo tse kholo kapa tse rarahaneng tsa geometri. Sena se senya ho nepahala ha dimensional, se eketsa litefiso le litefiso tsa mosebetsi hape, 'me se ja nako le lisebelisoa. Bakeng sa liindasteri tse kang tsa likoloi le tsa sefofane, moo ho mamellana ho thata ho leng bohlokoa, esita le warpage e nyenyane e ka fella ka ho hana likarolo.

Phallo e Mebe Melt

Ho eketsoa ha likhoele tsa khalase ho eketsa haholo viscosity ea ho qhibiliha, ho baka mathata a phallo nakong ea ente. Viscosity e phahameng ea ho qhibiliha e ka lebisa ho:

• Lits'oants'o tse khutšoane

• Weld mela

• Litšitiso tse holim'a metsi

Litaba tsena li na le mathata haholo bakeng sa likaroloana tsa lebota le tšesaane kapa likarolo tse nang le meralo e rarahaneng ea hlobo. Viscosity e phahameng e boetse e hloka khatello e matla ea ente, ho eketsa tšebeliso ea matla le khatello ea maikutlo ho lisebelisoa tsa ho bopa.

Accelerated Tool Wear

Likhoele tsa khalase lia hohla 'me li thata, li potlakisa ho koaheloa ha hlobo, limathi le li-nozzles. Ha ho etsoa ente le khatiso ea 3D, sena se khutsufatsa bophelo ba lisebelisoa, se phahamisa litšenyehelo tsa tlhokomelo, 'me se ka fokotsa nako ea tlhahiso. Bakeng sa khatiso ea 3D, likhoele tse nang le PA/GF li ka senya li-nozzles, tse amang boleng ba likarolo le tlhahiso.

Insufficient Interlayer Bonding (bakeng sa Khatiso ea 3D):

Lefapheng la tlhahiso ea li-additive, li-filaments tsa PA/GF li ka ba le maqhama a fokolang pakeng tsa lihlopha nakong ea khatiso. Sena se fella ka ho fokotsa thepa ea mechine ea likarolo tse hatisitsoeng, e leng se etsang hore li se ke tsa khona ho finyella litlhoko tse lebeletsoeng tsa matla le nako e telele.

Ntlha ea Bohloko ea 2: Ho pepeseha ha Fiber ea Khalase le Tšusumetso ea Eona

Ho pepeseha ha fiber ea khalase, e tsejoang hape e le "likhoele tse phaphametseng," ho etsahala ha likhoele li tsoa bokaholimo ba polima. Ketsahalo ena e ka ama bokhabane le ts'ebetso hampe:

Ponahalo e Senyehileng:Likamore li bonahala li le makukuno, tse sa leka-lekaneng le tse lerootho. Sena ha se amoheloe bakeng sa lits'ebetso tse hlokang boipiletso bo phahameng ba pono, joalo ka bokahare ba makoloi, matlo a elektroniki, le lisebelisoa tsa bareki.

Maikutlo a Foor Tactile:Libaka tse makukuno, tse ngoahang li fokotsa boiphihlelo ba basebelisi le boleng ba sehlahisoa se lemohuoang.

Nako e Fokotsoeng:Likhoele tse pepesitsoeng li sebetsa e le li-concentrators tsa khatello ea kelello, li theola matla a holim'a metsi le ho hanyetsa abrasion. Libakeng tse thata (mohlala, mongobo kapa ho pepesehela lik'hemik'hale), ho pepeseha ha fiber ho potlakisa botsofali le ho senyeha ha ts'ebetso.

Litaba tsena li thibela thepa ea PA/GF ho fihlela bokhoni ba eona bo felletseng, e qobella bahlahisi ho sekisetsa lipakeng tsa boleng, botle bo botle le katleho ea tlhahiso.

Litharollo tse Ncha bakeng sa Mathata a Ts'ebetso ea PA/GF

Likhatelo-pele tsa morao-rao tsa mahlale a lintho tse bonahalang, thekenoloji ea tlatsetso, le boenjiniere ba li-interface li fana ka tharollo e sebetsang litabeng tsena tsa nako e telele. Ka ho kopanya metsoako e fetotsoeng ea PA / GF, li-additives tse thehiloeng ho silicone, le lisebelisoa tsa ho lumellana le fiber-matrix, bahlahisi ba ka fokotsa ntoa, ba ntlafatsa ho phalla ha metsi, 'me ba fokotsa haholo ho pepeseha ha fiber ea khalase.

1. Lisebelisoa tsa PA / GF tsa Low-Warp

Lisebelisoa tsa PA/GF tse tlase-warp li etselitsoe ho sebetsana le warpage le deformation. Ka ho ntlafatsa:

• Mofuta oa fiber ea khalase (likhoele tse khutšoane, tse telele, kapa tse tsoelang pele)

• Kabo ea bolelele ba fiber

• Theknoloji ea phekolo ea holim'a metsi

• Resin sebopeho sa molek'hule

metsoako ena e fokotsa shrinkage ea anisotropic le khatello ea kelello ea ka hare, ho netefatsa botsitso ba likarolo tse rarahaneng tse entsoeng ka ente. Limaraka tse entsoeng ka mokhoa o ikhethileng oa PA6 le PA66 li bonts'a taolo e ntlafalitsoeng ea deformation nakong ea pholileng, ho boloka mamello e tiileng le boleng bo sa fetoheng ba karolo. 

2. Lisebelisoa tse phahameng tsa PA / GF

Lisebelisoa tse phahameng tsa PA/GF li sebetsana le phallo e mpe ea ho qhibiliha ka ho kenyelletsa:

• Lisebelisoa tse khethehileng

• Li-plasticizers

• Li-polymers tse nang le kabo ea boima ba molek'hule

Liphetoho tsena li fokotsa viscosity e qhibilihisitsoeng, e lumellang hlobo e rarahaneng hore e tlale hantle ka khatello e tlase ea ente. Melemo e kenyeletsa: ikatleho e ntlafalitsoeng ea tlhahiso, rba rutehileng sekoli litekanyetso, lho roala lisebelisoa le litšenyehelo tsa tlhokomelo.

Lisebelisoa tse thehiloeng ho Silicone

Lisebelisoa tsa silicone tsa SILIKE li sebetsa e le litlolo tse sebetsang hantle haholo le lithuso tsa ho sebetsa.

Likarolo tsa bona tse sebetsang tsa silicone li ntlafatsa kabo ea li-filler le ho phalla ha metsi, li eketsa phallo ea extruder ha li ntse li fokotsa tšebeliso ea matla. Tekanyetso e tloaelehileng: 1-2%, e lumellana le mafahla-screw extrusion.
