Njira zobwezereranso zinyalala zapulasitiki ndi ziti?

Pali njira zitatu zobwezeretsanso: 1. Chithandizo cha kuwonongeka kwa kutentha: Njira iyi ndi kutentha ndi kuwola mapulasitiki otayika kukhala mafuta kapena gasi, kapena kuwagwiritsa ntchito ngati mphamvu kapena kugwiritsanso ntchito njira zamakemikolo kuwalekanitsa kukhala zinthu za petrochemical kuti zigwiritsidwe ntchito.Njira ya kuwonongeka kwa matenthedwe ndi: polima amachotsa potentha kwambiri, ndipo maunyolo a maselo amathyoka ndikuwola kukhala mamolekyu ang'onoang'ono ndi ma monomers.Njira yowonongeka kwa kutentha ndi yosiyana, ndipo chomalizacho ndi chosiyana, chomwe chingakhale ngati mawonekedwe a monomer, ma polima otsika kwambiri, kapena osakaniza ma hydrocarbons angapo.Kusankhidwa kwa njira yopangira mafuta kapena gasification iyenera kutengera zosowa zenizeni.Njira zomwe zimagwiritsidwa ntchito ndi: tanki yosungunuka (ya PE, PP, PP, PS, PVC, etc.), mtundu wa microwave (PE, PP, PP, PS, PVC, etc.), mtundu wa screw (wa PE, PP) , PS, PMMA).Tube evaporator mtundu (wa PS, PMMA), ebullating bedi mtundu (wa PP, mwachisawawa PP, mtanda zogwirizana Pe, PMMA, PS, PVC, etc.), chothandizira kuwonongeka mtundu (kwa Pe, PP, PS, PVC, etc. ).Chovuta chachikulu pakuwola kwa mapulasitiki ndikuti mapulasitiki alibe matenthedwe abwino, zomwe zimapangitsa kuwonongeka kwakukulu kwamafuta m'mafakitale ndi kusweka kwamafuta kukhala kovuta kuchita.Kuphatikiza pakuwola kwamafuta, palinso njira zina zochizira mankhwala, monga kuphulika kwamafuta, hydrolysis, alcoholysis, alkaline hydrolysis, ndi zina zambiri, zomwe zimatha kuchira zopangira mankhwala osiyanasiyana.

2. Sungunulani zobwezeretsanso ntchito Njira iyi ndi yosankha, kuphwanya, ndi kuyeretsa zinyalala zamapulasitiki, kenako kuzisungunula ndi kuzipanga pulasitiki.Pazinthu zonyansa ndi zotsalira zochokera ku mafakitale opanga utomoni ndi mafakitale opangira pulasitiki ndi kupanga, njirayi ingagwiritsidwe ntchito kupanga zinthu zosiyanasiyana zabwinoko.Zimakhala zovuta kusankha ndi kuyeretsa mapulasitiki omwe amagwiritsidwa ntchito ndi anthu, ndipo mtengo wake ndi wokwera.Nthawi zambiri amagwiritsidwa ntchito popanga zinthu zovuta komanso zotsika mtengo.3. Kugwiritsanso ntchito kophatikizana: Njirayi ndikuphwanya mapulasitiki a zinyalala, monga zinthu za thovu la PS, thovu la PU, ndi zina zambiri m'zidutswa za kukula kwake, ndiyeno kuzisakaniza ndi zosungunulira, zomatira, ndi zina zambiri kuti apange matabwa opepuka ndi liners.
