Pamwe nekuchengetedza simba nekuchengetedza zviwanikwa zvakakosha, iko zvino kwave kuwedzera kutariswa kwekuona kuti zvigadzirwa zve polyurethane hazvisi kungoraswa kana kuraswa kana zvasvika kumagumo ehupenyu hwazvo.

Nokuti polyurethanespetrochemical-based polymers, zvakakosha kuti tizvishandise pazvinenge zvichiita, kuitira kuti zvinhu zvinokosha zvisaparare.Kune akasiyana siyana ekudzokorodza sarudzo, kusanganisira mechanical uye makemikari recycling.

Zvichienderana nerudzi rwepolyurethane, nzira dzakasiyana dzekudzokorodza dzinogona kuiswa, senge kukuya nekushandisa patsva kana particle bonding.Polyurethane foam, semuenzaniso, inogara ichishandurwa kuita carpet underlay.

Kana iyo isina kudzokororwa, sarudzo inosarudzwa ndeye simba rekudzoreredza.Tonne ye tonne, polyurethane ine simba rakafanana nemarasha, izvo zvinoita kuti rive rakanyanya kushanda zvakanaka rekudya kune masupaparati incinerators anoshandisa simba rinogadzirwa kupisa zvivakwa zveveruzhinji.

Iri diki rinodiwa sarudzo imarara, iyo inofanirwa kudzivirirwa pese pazvinogoneka.Sezvineiwo, sarudzo iyi iri kudzikira sezvo hurumende pasi rese dzichiwedzera kuziva kukosha kwemarara pakudzokorodza uye kudzoreredza simba, uye sezvo nyika dzinopedza simba radzo rekurasira.

Indasitiri ye polyurethane iri kuramba ichivandudza kugadzira zvinhu zvakatsiga.
