Nkag siab txog cov lej tsis meej thiab cov ntsiab lus hauv cov iav ntev fiber cuam tshuam txog polypropylene (LGFPP) Cheebtsam

Lub hauv paus rau phau ntawv

Cov iav ntev fiber ntau txhawb polypropylene (LGFPP)tau tawm los ua cov khoom siv cog lus rau cov ntawv thov kev lag luam vim nws lub zog tshwj xeeb, txhav, thiab lub teeb yuag. Txawm li cas los xij, txoj kev sib tw tseem ceeb cuam tshuam nrog LGFPP cov cheebtsam yog lawv qhov nyiam ua emit tsis muaj ntxhiab tsw. Cov neeg ntxhiab tsw no tuaj yeem tshwm sim los ntawm ntau qhov chaw, suav nrog lub hauv paus polypropylene (PP) Resin, ntev iav Fibers (LGBs), txuas cov txheej txheem moulding.

Cov khoom ntawm cov ntxhiab nyob hauv LGFPP Cheebtsam

1. Lub hauv paus Polypropylene (PP) Resin:

Kev tsim cov khoom siv pp, tshwj xeeb los ntawm cov txheej txheem peroxide tsis zoo, tuaj yeem qhia cov khoom seem uas ua rau muaj ntxhiab tsw. Hydrogenation, ib txoj kev lwm txoj hauv kev, tsim tawm pp nrog cov ntxhiab tsw tsawg thiab seem ntawm cov kab mob tsis sib haum.

2. Cov iav ntev fibers (LGBs):

LGBs lawv tus kheej yuav tsis tawm cov ntxhiab tsw, tab sis lawv txoj kev kho mob saum npoo nrog cov neeg sawv cev sib tw tuaj yeem ua kom pom cov tshuaj tsw qab.

3. Coupling Cov Neeg Sawv Cev:

Coupling cov neeg sawv cev, tseem ceeb rau kev txhim kho cov nplaum ntawm LGFs thiab lub PP matrix, tuaj yeem pab txhawb rau cov ntxhiab tsw. Txiv neej moov anhydride gradropylene (p-mah), ib qho kev sib tw txuas, tso tawm cov txiv neej tsis muaj mob thaum tsis muaj kev cuam tshuam thaum lub sij hawm tsim khoom.

4. Txhaj tshuaj molding:

Kev Txhaj Tshuaj Moulding Qhov kub thiab txias thiab kev lag luam tuaj yeem ua rau lub thermal degradation ntawm PP, tsim cov ntawv xaiv tsa tshiab xws li Aldehydes thiab Ketones.

Cov tswv yim los txo ntxhiab tsw hauv LGFPP cov khoom siv

1. Cov khoom xaiv:

• Ua haujlwm hydrogenated pp resin kom txo cov khoom seem thiab tsw.
• Xav txog lwm txoj kev txuas los yog ua kom zoo dua PP-G-Mah Graft txheej txheem los txo cov txiv neej uas tsis raug.

2. Txheej Txheem Txhim Kho Kom Zoo:

• Txo kev txhaj tshuaj molding kub thiab kev ua kom raug kom txo pp kev tsis tshwm sim.
• Ua haujlwm tau zoo pwm kom tshem tawm cov teb chaws tsis sib txuas thaum maub.

3. Cov kev kho mob tom qab:

• Siv cov ntxhiab tsw -kas ntsej muag lossis cov adsorbents los nruab nrab lossis ntes cov ntxhiab tsw.
• Txiav txim siab txog ntshav lossis kev kho corona hloov kho cov kev siv dag zog hauv LGFPP, txo qis tiam.

LGFPP muaj cov txiaj ntsig tseem ceeb rau cov ntawv thov siv khoom lag luam, tab sis cov teeb meem ntxhiab tuaj yeem tuaj yeem cuam tshuam nws cov kev saws me nyuam. Los ntawm kev nkag siab cov khoom ntawm cov ntxhiab thiab kev siv cov tswv yim tsim nyog, cov tuam txhab tsim nyog tuaj yeem txhim kho cov kev ua tau zoo thiab ua tiav ntawm LGFPP cov khoom.
