Fahimtar Ƙarfafa Ƙwarri da Magani a cikin Dogon Gilashin Fiber Reinforced Polypropylene (LGFPP)

Gabatarwa

Dogon Gilashin Fiber Ƙarfafa Polypropylene (LGFPP)ya fito a matsayin abu mai ban sha'awa don aikace-aikacen mota saboda ƙaƙƙarfan ƙarfinsa, taurinsa, da kaddarorin nauyi. Koyaya, babban ƙalubale mai alaƙa da abubuwan LGFPP shine halayensu na fitar da wari mara daɗi. Wadannan wari na iya fitowa daga wurare daban-daban, ciki har da resin polypropylene (PP), dogayen zaruruwan gilashin (LGFs), jami'an haɗin gwiwa, da tsarin gyaran allura.

Tushen Odor a cikin Abubuwan LGFPP

1. Base Polypropylene (PP) Guduro:

Samar da resin PP, musamman ta hanyar lalatawar peroxide, na iya gabatar da ragowar peroxides waɗanda ke taimakawa ga wari. Hydrogenation, madadin hanyar, yana samar da PP tare da ƙaramin ƙamshi da gurɓataccen ƙazanta.

2. Dogon Gilashin Fiber (LGFs):

LGFs da kansu ba za su fitar da wari ba, amma jiyyarsu ta saman tare da abubuwan haɗin gwiwa na iya gabatar da abubuwa masu haifar da wari.

3. Wakilan Haɗawa:

Abubuwan haɗin gwiwa, masu mahimmanci don haɓaka mannewa tsakanin LGFs da matrix PP, na iya ba da gudummawa ga wari. Maleic anhydride grafted polypropylene (PP-g-MAH), wakili na gama gari, yana sakin anhydride na namiji mai wari lokacin da bai cika amsawa ba yayin samarwa.

4. Tsarin gyare-gyaren allura:

Babban yanayin gyare-gyaren allura da matsa lamba na iya haifar da lalacewar thermal na PP, yana haifar da mahaɗan maras kyau kamar aldehydes da ketones.

Dabarun Rage wari a Abubuwan LGFPP

1. Zabin Abu:

• Yi amfani da guduro na PP hydrogenated don rage ragowar peroxides da wari.
• Yi la'akari da madadin abubuwan haɗin haɗin gwiwa ko inganta tsarin grafting na PP-g-MAH don rage ƙwayar anhydride na namiji da ba a yi ba.

2. Inganta Tsari:

• Rage yanayin gyare-gyaren allura da matsa lamba don rage lalata PP.
• Yi amfani da ingantacciyar iska mai kyalli don cire mahaɗar mahalli yayin gyare-gyare.

3. Magani Bayan Gyara:

• Yi amfani da wakilai masu sanya wari ko adsorbents don kashe ko kama kwayoyin wari.
• Yi la'akari da magani na plasma ko corona don gyara sinadarai na saman abubuwan LGFPP, rage haɓakar wari.

Kammalawa

LGFPP yana ba da fa'idodi masu mahimmanci don aikace-aikacen mota, amma al'amuran wari na iya hana ta karɓuwa. Ta hanyar fahimtar tushen wari da aiwatar da dabarun da suka dace, masana'antun za su iya rage wari yadda ya kamata da haɓaka aikin gabaɗaya da roƙon abubuwan LGFPP.
