Kunzwisisa kunhuhwirira kwechizvarwa uye mhinduro mune refu girazi fiber yakasimbiswa polypropylene (LGFPP) zvikamu

Nhanganyaya

Refu girazi fiber yakasimbiswa polypropylene (LGFPP)yakabuda sechinhu chinovimbisa zvekushandisa zvemotokari nekuda kwesimba rayo rakasarudzika, kuomarara, uye kuremerwa. Nekudaro, chinetso chakakosha chakabatana neLGFPP zvikamu ndezvekuti tarisiro yavo yekubvisa kusafadza kwekunyepedzera. Uku kunhuhwirira kunogona kumuka kubva kune dzakasiyana siyana masosi, kusanganisira iyo base polypropylene (PP) resin, refu girazi machira (LGFS), maAgnling macomputer, uye jekiseni rakaumbwa.

Source of Odor muLGFPPPP zvikamu

1. Base polypropylene (PP) resin:

Iko kugadzirwa kwePP Resin, kunyanya kuburikidza neye peroxide yekushambadzira nzira, inogona kuunza yakasara maperembudzi inopa kune kunhuhwirira. Hydrogenation, imwe nzira, inoburitsa pp ine kunhuhwirira kushoma uye kusara kusara.

2. Yakareba girazi machira (LGFS):

Zvicho moteshiti ivo pachavo vangasatarisa kunhuhwirira, asi kurapwa kwavo kune vamiririri vekodhi kunogona kuunza kunhuhwirira-kukonzera zvinhu zvinokonzeresa.

3. Coupling vamiririri:

Compling vamiririri, zvakakosha kuti uwedzere kusungirirwa pakati peLGFS uye PP Matrix, inogona kubatsira kune kunhuhwirira. Maleic Anhydride akaprofed Polypropylene (PP-G-MAH), akajairika kuunganidza mumiririri, anoburitsa odous maleic andeddride kana asina kunyatsoitwa panguva yekugadzira.

4. Jekiseni kuumbwa maitiro:

Yakakura jekiseni inoumbwa tembiricha uye dzvinyiriro dzinogona kutungamira kune iyo yekunyora kusvibiswa kwePP, kugadzira ine mishonga ine madhiri yakadai seAldehydes neKetoni.

Strategies kusvika kuMitigate kunhuhwirira muLGFPP zvikamu

1. Kusarudzwa kwezvinhu:

• Shandisa hydrogenated pp resin kuti uderedze zvakasara maperexide uye kunhuhwirira.
• Funga nezve dzimwe nzira dzakapetwa mumudziyo kana isaira PP-G-MAG-MAGFTING maitiro ekudzora zvisina kufanira anewydride.

2. Process optimization:

• Kuderedza jekiseni inoumba tembiricha uye dzvinyiriro kuderedza PP kusvibiswa.
• Shandisa inoshanda mold yekuvhara kuti ubvise mishonga isina kujairika panguva yekuumbwa.

3. Post-kugadzirisa kurapwa:

• Shandisa odor-masking vamiririri kana adsorbents kusapindira kana kubata zvinonhuwira mamorekuru.
• Funga nezve plasma kana corona kurapwa kugadzirisa chemistry yeLGFPPPL, kuderedza kwechizvarwa chechizvarwa.

Mhedziso

LGFPPP Inopa Zvakakosha Zvakanakira Zvekushandisa Zvekushandisa, asi zvinonhuwira zvinokanganisa kuuraya kwayo kwakapararira. Nekunzwisisa masosi ekunhuhwirira uye kuita zviyero zvakakodzera, vagadziri vanogona kuita kunhuhwirira kunhuhwirira uye kusimudzira maitiro ekuita uye kukwirira kweLGFPP zvikamu.
