lihlahisoa

Bakeng sa bahlahisi ba lefats'e ka bophara ba likoloi, lisebelisoa tsa lapeng le indasteri, Long Glass Fiber Reinforced Polypropylene (LGFPP) ke thepa ea bohlokoa bakeng sa ho bebofatsa le ho ntlafatsa litšenyehelo. Joaloka moetsi oa litsebi oa LGFPP, re hlophisitse tataiso ena e qaqileng ea ho reka ho thusa bareki ba machabeng ho khetha lihlahisoa tse nepahetseng, ho qoba maraba a tloaelehileng, le ho utloisisa lipapiso tsa mehlala.

1. Melemo ea Bohlokoa ea LGFPP khahlanong le SGFPP

Li-pellet tsa LGFPP li boloka bolelele ba faeba ba 3–25mm, li etsa sebopeho sa marang-rang sa 3D kamora ho bopa, ka melemo e meholo ea ts'ebetso ho feta PP e khuts'oane e matlafalitsoeng ea faeba (SGFPP):

- Matla a Mekaniki: Matla a ho thapolla a phahameng ka 20–30%, matla a ho shapuoa a phahameng ka makhetlo a 2–3, le ho tiea ho babatsehang ha mocheso o tlase

- Botsitso ba Dimensional: Ho ba le warpage e nyane, e loketseng dikarolo tse kgolo tsa sebopeho

- Ho Sebetsa ka Botlalo: E bobebe ho feta tšepe, e theko e tlase ho feta PA66, 'me ha ho hlokahale hore e omisoe pele e omisoa

2. Mekhoa ea Khetho ea Bohlokoa bakeng sa LGFPP

2.1 Dikahare tsa Faeba (10%–50%)

- 10–20% LGFPP: Ho tiea le ho tiea ho leka-lekaneng, ho loketse likarolo tsa sebopeho ka kakaretso

- 30% LGFPP: Tekanyetso ea indasteri bakeng sa ho tiea ho hoholo, e sebelisoang haholo likarolong tsa likoloi

- 40–50% LGFPP: Matla a phahameng haholo bakeng sa lits'ebetso tsa mojaro o boima

2.2 Liparamente tsa Ts'ebetso ea Bohlokoa

- Sekhahla sa Phallo ea ho Qhibiliha (MFR): 5–30 g/metsotso e 10; MFR e phahameng bakeng sa likarolo tse rarahaneng tsa lebota le lesesaane

- Mocheso oa ho Fokotsa Mocheso (HDT): 140–170°C; e bohlokoa bakeng sa libaka tse nang le mocheso o phahameng

- Matla a Tšusumetso: >50 kJ/m² bakeng sa litlhoko tsa ho thibela ho oa le ho thibela ho thothomela

- Ho Thibela Lelakabe: UL94 HB/V0 bakeng sa lits'ebetso tsa motlakase

2.3 Ho Bapisa Ts'ebeliso

- Likoloi: Li-bumper, liphanele tsa mamati, literei tsa betri (30–40% LGFPP, tšusumetso e phahameng)

- Lisebelisoa tsa Lapeng: Meropa ea mochini o hlatsoang, mahare a fene (20–30% LGFPP, warpage e tlase)

- Indasteri: Mabokose a lisebelisoa, li-fitting tsa liphaephe (30–50% LGFPP, e jarang mojaro o moholo)

- Kantle: Mekhahlelo e tsitsitseng ea UV bakeng sa ho hanyetsa boemo ba leholimo ba nako e telele

3. Likotsi tse Tloaelehileng tsa ho Reka le Malebela a ho Qoba

3.1 Ho ferekanya LGFPP le SGFPP

- Leraba: Lihlahisoa tsa "faeba e telele" tse theko e tlase tse nang le bolelele ba faeba ea kamora ho bopa <1mm

- Tharollo: Netefatsa ho bolokoa ha bolelele ba fiber le ho kopa litlaleho tsa liteko tsa tšusumetso

3.2 Boleng ba Sehlopha bo sa Tsitseng

- Kotsi: Phapang ea ts'ebetso lipakeng tsa lihlopha e bakang mathata a tlhahiso

- Tharollo: Khetha bahlahisi ba nang le setifikeiti sa ISO9001/TS16949 le taolo e tiileng ea boleng

3.3 Ho Hlokomoloha ho Tsamaellana ha Ts'ebetso

- Kotsi: MFR e sa lokelang e lebisang ho phallo e mpe kapa ho robeha ha faeba

- Tharollo: Netefatsa hore MFR e tsamaisana le liparamente tsa lisebelisoa tsa hau tsa ho bōpa ka ente

3.4 Ho hlokomoloha Litlhoko tsa Setifikeiti

- Kotsi: Lisebelisoa tse sa lateleng melao li hlōleha ho fumana 'maraka ka liteko tse fapaneng

- Tharollo: Beha lihlahisoa pele ka setifikeiti sa FDA, RoHS, le UL

4. Tafole e Tloaelehileng ea Papiso ea Mohlala

Tensile Strength HDT (0.45MPa) Tšebeliso e Tloaelehileng ea Moetso oa Faeba

Matlo a bobebe a LGFPP10 10% 35–45 MPa 120–130°C

Likarolo tsa lisebelisoa tsa lapeng tsa LGFPP20 20% 50–65 MPa 130–140°C

LGFPP30 30% 70–90 MPa 140–155°C Likarolo tsa meaho ea likoloi

LGFPP40 40% 90–110 MPa 150–165°C Dikarolo tse boima

Lisebelisoa tsa indasteri tsa LGFPP50 50% 110–130 MPa 160–175°C

5. Hobaneng re ka re Khetha?

- Tlhahiso ea Litsebi: Mela e khethehileng ea tlhahiso ea LGFPP e nang le taolo e tsitsitseng ea bolelele ba faeba

- Ho iketsetsa: Iketsetse dikahare tsa faeba, di-additives, le tshebetso ho latela ditlhoko tsa hao

- Phepelo e Tsitsitseng: Thepa e kholo le phano e tenyetsehang bakeng sa bareki ba lefats'e ka bophara

- Tšehetso ea Tekheniki: Tataiso ea mahala ea tlhahlobo ea sampole le ntlafatso ea ts'ebetso

Qetello

Ho khetha LGFPP ea boleng bo holimo ho hloka ho leka-lekanya ts'ebetso, ts'ebeliso le litšenyehelo. Ka ho latela tataiso ena, u ka qoba likotsi tsa ho reka 'me ua fumana tharollo e ntle ea thepa. Ikopanye le rona bakeng sa litheko tse ikhethileng le tšehetso ea tekheniki—molekane oa hau ea tšepahalang oa LGFPP bakeng sa katleho ea tlhahiso ea lefats'e.
