Ndedzipi nzira dzekushandisa patsva mapurasitiki emarara?

Pane nzira nhatu dzekugadzirisa zvakare: 1. Kurapa kwekuora kwekupisa: Iyi nzira ndeyekupisa uye kuparadza mapurasitiki emarara mumafuta kana gasi, kana kuashandisa sesimba kana kushandisazve nzira dzemakemikari kuti azviparadzanise kuita petrochemical zvigadzirwa kuti zvishandiswe.Maitiro ekuora kwekushisa ndeichi: iyo polymer inobvisa pakupisa kwakanyanya, uye cheni dzemamorekuru dzinotyora nekuora kuita mamorekuru madiki uye monomers.Kuora kwekushisa kwakasiyana, uye chigadzirwa chekupedzisira chakasiyana, chinogona kunge chiri muchimiro chemonomer, low molecular weight polymer, kana musanganiswa wemahydrocarbon akawanda.Sarudzo yeoiri kana gasification process inofanirwa kuenderana nezvinodiwa chaizvo.Nzira dzinoshandiswa ndeidzi: tangi yekunyunguduka (yePe, PP, random PP, PS, PVC, nezvimwewo), microwave mhando (PE, PP, random PP, PS, PVC, nezvimwewo), screw type (ye PE, PP , PS, PMMA).Tube evaporator type (yePS, PMMA), ebullating bed type (yePP, random PP, cross-linked PE, PMMA, PS, PVC, etc.), catalytic decomposition type (yePE, PP, PS, PVC, nezvimwewo. )Chinetso chikuru mumapurasitiki ekuora ari kupisa nderekuti mapurasitiki ane hurombo hwekupisa conductivity, izvo zvinoita kuti maindasitiri akakura-kuora kwekupisa kwekupisa uye kutsemuka kwemafuta kunetsa kuita.Pamusoro pekuora kwekupisa, kune dzimwe nzira dzekurapa makemikari, senge thermal cracking, hydrolysis, alcoholysis, alkaline hydrolysis, nezvimwewo, inogona kudzoreredza akasiyana makemikari zvinhu.

2. Melt recycling Iyi nzira ndeyekuronga, kupwanya, uye kuchenesa marara epurasitiki, uye ozonyungudusa nekuaisa mupurasitiki.Kune zvigadzirwa zvemarara uye zvinhu zvakasara kubva kumiti yekugadzira resin uye mapurasitiki ekugadzirisa nekugadzira zvidyarwa, nzira iyi inogona kushandiswa kugadzira zvigadzirwa zvakasiyana zvine mhando iri nani.Zvinonetsa kuronga nekuchenesa mapurasitiki akaraswa anoshandiswa munharaunda, uye mutengo wakakwira.Iwo anowanzo shandiswa kugadzira rough uye yakaderera-yekupedzisira zvigadzirwa.3. Kushandiswazve kweComposite: Iyi nzira ndeyekupwanya marara epurasitiki, akadai sePS foam zvigadzirwa, PU foam, nezvimwewo kuita zvidimbu zvehumwe saizi, wozozvisanganisa nezvinonyungudutsa, zvinonamira, nezvimwewo kugadzira mapuranga akareruka uye liner.
