cov khoom

Rau cov tuam txhab tsim khoom thoob ntiaj teb hauv kev tsim tsheb, cov khoom siv hauv tsev, thiab kev lag luam, Long Glass Fiber Reinforced Polypropylene (LGFPP) yog cov khoom siv tseem ceeb rau kev ua kom lub cev sib dua thiab txo nqi. Ua ib tus kws tshaj lij LGFPP chaw tsim khoom, peb tau sau cov lus qhia txog kev yuav khoom no los pab cov neeg yuav khoom thoob ntiaj teb xaiv cov khoom zoo, zam kev ua yuam kev, thiab nkag siab txog kev sib piv cov qauv.

1. Cov txiaj ntsig tseem ceeb ntawm LGFPP piv rau SGFPP

Cov pellets LGFPP khaws cov fiber ntev ntawm 3–25 hli, tsim cov qauv 3D network tom qab molding, nrog rau qhov zoo dua li cov fiber luv luv reinforced PP (SGFPP):

- Lub Zog Kho Tshuab: Lub zog tensile siab dua 20–30%, lub zog cuam tshuam siab dua 2–3 zaug, thiab lub zog tawv zoo heev thaum kub qis

- Kev Ruaj Ntseg ntawm Qhov Ntev: Tsawg kawg nkaus warpage, zoo tagnrho rau cov khoom loj

- Kev Siv Nyiaj Txiag: Sib dua li hlau, pheej yig dua PA66, thiab tsis tas yuav ziab ua ntej

2. Cov Qauv Xaiv Tseem Ceeb rau LGFPP

2.1 Cov Khoom Noj Muaj Fiber (10%–50%)

- 10–20% LGFPP: Kev sib npaug ntawm kev ruaj khov thiab kev tawv, tsim nyog rau cov khoom siv dav dav

- 30% LGFPP: Tus qauv kev lag luam rau kev ruaj khov siab, siv dav hauv cov khoom siv tsheb

- 40–50% LGFPP: Lub zog siab heev rau cov ntawv thov hnyav

2.2 Cov Qauv Tseem Ceeb ntawm Kev Ua Haujlwm

- Melt Flow Rate (MFR): 5–30 g/10 feeb; MFR siab dua rau cov khoom nyias nyias uas nyuaj

- Qhov Kub Uas Ua Rau Kub Tawg (HDT): 140–170°C; tseem ceeb rau cov chaw kub heev

- Lub zog cuam tshuam: >50 kJ/m² rau kev tiv thaiv kev poob thiab kev tiv thaiv kev poob siab

- Hluav Taws Kub Tiv Thaiv: UL94 HB / V0 rau kev siv hluav taws xob

2.3 Kev Sib Txuas Lus ntawm Daim Ntawv Thov

- Tsheb: Cov khoom siv thaiv qhov rooj, cov qhov rooj vaj huam sib luag, cov tais roj teeb (30–40% LGFPP, muaj zog heev)

- Cov Khoom Siv Hauv Tsev: Lub tshuab ntxhua khaub ncaws, cov kiv cua (20–30% LGFPP, tsis tshua muaj kev sib txhuam)

- Kev Lag Luam: Cov thawv cuab yeej, cov khoom siv yeeb nkab (30–50% LGFPP, muaj lub nra hnyav)

- Sab nraum zoov: Cov qib UV-stabilized rau kev tiv taus huab cua ntev

3. Tej Yam Uas Yuav Tsum Tau Ua Thiab Cov Lus Qhia Txog Kev Zam Thaum Yuav Khoom

3.1 Kev Tsis Sib Haum LGFPP nrog SGFPP

- Qhov Tsis Zoo: Cov khoom lag luam "ntev fiber" pheej yig uas muaj qhov ntev ntawm cov fiber tom qab molding <1 hli

- Kev daws teeb meem: Txheeb xyuas qhov ntev ntawm cov fiber thiab thov cov ntawv qhia txog kev ntsuam xyuas cuam tshuam

3.2 Qhov Zoo ntawm Cov Khoom Uas Muab Tsis Sib Xws

- Qhov Tsis Zoo: Kev ua haujlwm sib txawv ntawm cov pawg ua rau muaj teeb meem ntau lawm

- Kev daws teeb meem: Xaiv cov chaw tsim khoom uas muaj daim ntawv pov thawj ISO9001 / TS16949 thiab kev tswj hwm zoo nruj

3.3 Tsis quav ntsej txog kev sib raug zoo ntawm cov txheej txheem

- Qhov Pitfall: MFR tsis haum ua rau cov dej ntws tsis zoo lossis cov fiber tawg

- Kev daws teeb meem: Paub meej tias MFR phim koj cov khoom siv txhaj tshuaj molding

3.4 Saib Tsis Tau Cov Kev Cai ntawm Daim Ntawv Pov Thawj

- Qhov Tsis Zoo: Cov ntaub ntawv tsis ua raws li qhov kev sim nkag mus rau hauv kev ua lag luam

- Kev daws teeb meem: Muab cov khoom lag luam uas muaj daim ntawv pov thawj FDA, RoHS, thiab UL tso ua ntej

4. Cov Lus Qhia Sib Piv Txog Tus Qauv Txheem

Qauv Cov Ntsiab Lus Fiber Tensile Zog HDT (0.45MPa) Daim Ntawv Thov Ib Txwm Muaj

LGFPP10 10% 35–45 MPa 120–130°C Cov tsev sib zog me me

LGFPP20 20% 50–65 MPa 130–140°C Cov khoom siv hauv tsev

LGFPP30 30% 70–90 MPa 140–155°C Cov khoom siv hauv tsheb

LGFPP40 40% 90–110 MPa 150–165°C Cov khoom siv hnyav
