Furo repurasitiki rinopushwa sei? Jenareta rehutsi rinokuudza mhinduro

"Plastiki foam" imhando yepolymer inoumbwa nehuwandu hukuru hwegasi micropores yakaparadzirwa mupurasitiki yakasimba.Iyo ine hunhu hwehuremu huremu, kupisa kupisa, kunyudza inzwi, kubatwa nekuvhunduka, zvichingodaro, uye zvimiro zvayo zvedielectric zviri nani pane resin.Nhasi, kushandiswa kwayo munharaunda kwakakura zvekuti chero plastiki inogona kugadzirwa kuita Styrofoam.Iyo zvakare imwe yemapurasitiki anoshandiswa zvakanyanya pasi rose.Mukugadzirwa kwefuro repurasitiki, inofanirwa kuitwa pasi pechiito chekushisa kwakanyanya uye yakakwira yekumanikidza catalyst, uye iyo polymerization reaction inoitika mune yakavharwa reactor.Iyo steam jenareta zvakare imwe yeakakosha midziyo yekugadzira yefoam plastiki fekitori kugadzira purasitiki yefuro.Iyo inonyanya kupa yemhando yepamusoro soro yekugadzira furo uye inobatsira kupupa.
1. Kemikari inoputika furo: kunyanya kushandisa kemikari inopupuma furo, zvichingodaro, kugadzira mabhuru mupurasitiki kuburikidza nekuora kwekupisa.Iri bhubhu rinonyanya kuwanikwa mu polyurethane furo, uye mukuita uku, jenareta rehutsi rinodiwa kuti ripe yakagadzikana yekupisa sosi yekuora.Yedu steam jenareta inogona kupa yakagadzikana kupisa sosi, uye nguva uye tembiricha zvinogona kugadziridzwa, kuitira kuti kemikari inopupuma Iyo nzira haizokanganiswe.
2. Kupupa kwepanyama: nyungudutsa plastiki nemamwe magasi uye zvinwiwa, uye wozoita kuti plastiki iwedzere.Iyi nzira haishandure chimiro chepakutanga chepurasitiki.Mukuita uku, yechitatu-bato yekuwedzera mhedzisiro inoshandiswa kufefetedza epurasitiki.Jenareta rehutsi rinoshandiswa kupa sosi yekupisa yekunyungudutsa mamwe magasi uye zvinwiwa mupurasitiki, iyo inobva yaburitsa maitiro ekuwedzera kwezvinhu.
3. Mechanical foaming: Nzira yekusanganiswa kwemagetsi inonyanya kushandiswa kunyungudutsa gasi mumusanganiswa uye kuibudisa kunze nesimba rekunze.Mukuita uku, jenareta rehutsi rinodiwawo kubatsira.
Naizvozvo, iyo steam jenareta yakakodzera kwazvo kugadzirwa kwepurasitiki furo.Nzira dzakasiyana dzekupupa dzinoda kushandiswa kwemajenareta eutsi, uye kudiwa kwenyika kwekupupa kunoda kusangana nehutsanana hwechikafu.Iko kushandiswa chaiko kwema boilers echinyakare kwakadzikira.Iyo steam inogadzirwa nemajenareta edu ehutsi ndeyepamusoro-tembiricha uye yakachena, iyo inoenderana zvizere nemitemo yenyika.
Nobles steam jenareta anoshandiswa zvakanyanya kwete chete muindasitiri yefuro yepurasitiki, asiwo muindasitiri yechikafu, indasitiri yezvokurapa, indasitiri yemagetsi, indasitiri yekuchenesa, kurima greenhouse, kupisa uye mamwe maindasitiri.Majenareta edu ese ari kushandiswa.
