Nhanganyaya:
Plastics anoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kwekusiyana-siyana uye mutengo-unoshanda.Nekudaro, kupisa kwavo kunounza njodzi dzinogona kuitika, zvichiita kuti murazvo udzoke ive nzvimbo yakakosha yekutsvaga.Ichi chidzidzo chekuedza chine chinangwa chekuongorora kushanda kwezvakasiyana-siyana zvinodzoreredza murazvo mukusimudzira kuramba kwemoto kwemapurasitiki.
Nzira:
Muchidzidzo ichi, takasarudza marudzi matatu anowanzo shandiswa emapurasitiki: polyethylene (PE), polypropylene (PP), uye polyvinyl chloride (PVC).Mhando yega yega yepurasitiki yakabatwa nemhando nhatu dzakasiyana dzemoto, uye midziyo yavo isingadziviriri moto yakaenzaniswa nemasampuli asina kurapwa.Zvidzoreso zvemurazvo zvaisanganisira ammonium polyphosphate (APP), aluminium hydroxide (ATH), uye melamine cyanrate (MC).
Maitirwo Ekuedza:
1. Kugadzirira Kwemuenzaniso: Zvienzaniso zvemhando imwe neimwe yepurasitiki yakagadzirirwa maererano nehukuru hwemazuva ose.
2. Flame Retardant Treatment: Izvo zvakasarudzwa zvinopisa moto (APP, ATH, uye MC) zvakasanganiswa nemhando imwe neimwe yepurasitiki inotevera zviyero zvakakurudzirwa.
3. Kuedza Kwemoto: Masampuli epurasitiki akabatwa uye asina kubatwa akaiswa pasi pemoto wakadzorwa wemoto uchishandisa Bunsen burner.Nguva yekubatidza, murazvo wakapararira, uye chizvarwa cheutsi zvakacherechedzwa uye kurekodhwa.
4. Kuunganidza Data: Zviyero zvaisanganisira nguva yekudzima, kupararira kwemoto, uye kuongororwa kwekuona kwekugadzirwa kweutsi.
Mhinduro:
Mhedzisiro yekutanga inoratidza kuti ese matatu emurazvo anodzosa moto akavandudza kudzivirira kwemoto kwemapurasitiki.Iwo masampula akabatwa airatidza nguva refu yekubatidza uye kunonoka kwemurazvo kupararira zvichienzaniswa nemasampuli asina kurapwa.Pakati pevakaregeredza, APP yakaratidza kuita kwakanyanya kwePE nePVC, nepo ATH yakaratidza mhedzisiro inoshamisa yePP.Kugadzirwa kwehutsi hudiki kwakaonekwa mumasampuli akarapwa pamapurasitiki ese.
Hurukuro:
Kuvandudzwa kwakacherechedzwa mukudzivirirwa nemoto kunoratidza kugona kweizvi zvinodzosa moto kuwedzera kuchengetedzwa kwezvinhu zvepurasitiki.Misiyano yekushanda pakati pemhando dzepurasitiki uye zvinodzosa moto zvinogona kukonzerwa nekusiyana kwekuumbwa kwemakemikari uye chimiro chemidziyo.Kumwe kuongorora kunodiwa kuti tinzwisise nzira dzepasi dzinokonzeresa zvakaonekwa.
Mhedziso:
Ichi chidzidzo chekuyedza chinosimbisa kukosha kwekudzoreredza kwemurazvo mumapurasitiki uye inoburitsa zvakanaka mhedzisiro yeammonium polyphosphate, aluminium hydroxide, uye melamine cyanrate sezvinoshanda zvinodzosa moto.Zvakawanikwa zvinobatsira mukugadzirwa kwezvinhu zvakachengeteka zvepurasitiki zvekushandisa zvakasiyana, kubva pakuvaka kusvika kune zvevatengi.
Dzimwe Tsvakurudzo:
Tsvagiridzo yeramangwana inogona kupenengura mukukwenenzverwa kwereshiyo inodzosa moto, kugadzikana kwenguva refu kwemapurasitiki akarapwa, uye kukanganisa kwezvakatipoteredza kweizvi zvinodzosa moto.
Nekuita chidzidzo ichi, tine chinangwa chekupa ruzivo rwakakosha mukufambiswa kwemapurasitiki asingabati murazvo, kukurudzira zvinhu zvakachengeteka uye kuderedza njodzi dzine chekuita nekupisa kwepurasitiki.
