Momwe Mungathetsere Fungo la Zinthu Zomangira Majekeseni?

Opanga jekeseni akamaumbakugula particles oyenerera pulasitiki, amene ndi chitsimikizo chofunika kuonetsetsa kuti jekeseni akamaumba mankhwala alibe fungo.Ponena za mapulasitiki ena, omwe ali ndi fungo linalake, opanga jekeseni amafunikira kuchitapo kanthu asanapangidwe.

Jekeseni akamaumba mankhwala si chofunika kuti akhale oyenerera, koma ngati opangidwa jekeseni akamaumba mbali ndi fungo lachilendo, adzakhala ndi zotsatira zoipa kwa makasitomala.Makamaka, ena opanga jekeseni amagwiritsa ntchito tinthu tapulasitiki toyenerera, ndipo kununkhira kowonjezereka kwachilendo kumakhudza mwachindunji kugula kwa ogula.Choncho, mankhwala kukonzedwa kudzerajekeseni nkhunguziyenera kutsimikiziridwa kuti zilibe fungo loipa lachilendo.

1. Yang'anirani mwamphamvu kugwiritsa ntchito zowonjezera

Chothandizira chapamwamba cha amine chomwe chimagwiritsidwa ntchito popanga thovu la polyurethane chidzabweretsa fungo lamphamvu ndi chifunga pawindo lamkati lagalimoto.Titha kupeza m'malo mwa ma amines kuti tigwiritse ntchito mankhwala a polyhydroxy.Polyhydroxy mankhwala si zigawo zikuluzikulu za unyolo polyurethane maselo, komanso ndi chothandizira ntchito.Mankhwala ena a polyhydroxy amatha kusintha theka la chothandizira chapamwamba cha amine, Fungo la mankhwala opangira jekeseni limakhala lofooka.

2. Sankhani zambiri koyera utomoni

Mu nkhungu zambiri za pulasitiki, makamaka muZithunzi za PVC, styrene, poly (ethyl acetate) ndi acrylate, zotsalira zotsalira za monomers zidzakhala ndi fungo losasangalatsa.Ngati utomoni wopanda fungo umasankhidwa, zotsatira zake zidzakhala bwino.

3. Samalani kugwiritsa ntchito adsorbent

Ngati zeolite zochepa zadzazidwa mu polima, fungo la zinthuzo likhoza kuchotsedwa.Ma Zeolite ali ndi hollowness yambiri ya kristalo, yomwe imatha kugwira mamolekyu ang'onoang'ono agasi ndi fungo.

Opanga jekeseni amagula tinthu tating'onoting'ono tapulasitiki, chomwe ndi chitsimikizo chofunikira kuonetsetsa kutijekeseni akamaumba mankhwalaalibe fungo.Ponena za mapulasitiki ena, omwe ali ndi fungo linalake, opanga jekeseni amafunikira kuchitapo kanthu asanapangidwe.
