Gushonga Urugendo (MFI) na Polymer Gutunganya

Niki gituma polymers byoroshye gushiraho no gutunganya? Igisubizo kiri mumyandikire yashonga (MFI). MFI ingamba uburyo byoroshye gushonga no gutemba, gukina uruhare rukomeye mugukora polymer. Ni ngombwa guhitamo uburyo bukwiye bwo gutunganya no kwemeza ko ibicuruzwa. Muri iyi nyandiko, uzamenya ishingiro rya MFI, akamaro kayo muburyo bwo gutunganya, nuburyo bitanga umusaruro wibicuruzwa. Tuzareba kandi ibintu bigira ingaruka mfi, inzira zo kugihindura, nuburyo ikoreshwa muburyo bwiza.

Ni ubuhe butumwa bwo gushonga (MFI)?

Gushonga Urugendo (MFI) gikora nk'ibipimo ngenderwaho binegura bipima ibyuma byo kwirangirwa cyangwa gushonga. Byerekana uburyo byoroshye polymes byoroshye gutemba muburyo bwihariye nubushyuhe.

Gusobanukirwa mfi nibipimo byayo

MFI yerekana igipimo cyimiterere ya gipimishijwe binyuze mu gupfa bisanzwe mubihe byateganijwe:

• Igisobanuro : Uburemere (muri garama) ya Polymer atemba binyuze muminota 10

• Ibipimo byo kwipimisha :

• Gupfa diameter nuburebure (bisanzwe)

• Imyitozo ngororamubiri (uburemere)

• Ubushyuhe bugenzurwa

MFI nkibipimo byumutungo

MFI Colledations ibiranga byinshi bya polymer:

1. Ibintu bya molekale :
