Zvimiro zveChigadzirwaChitarisiko
(1)Kugadzikana kwakanaka kwemakemikari: Inoratidza kusagadzikana, kuramba maasidhi akasimba (kunze kwehydrofluoric acid), alkalis akasimba, aqua regia, uye organic solvents dzakasiyana-siyana dzemishonga yakawanda yemakemikari uye solvents.
(2) Kukwikwidzana kwakakwirira: Ndiyo imwe yemhando dzakaderera dzekukweshana pakati pezvinhu zvakasimba (0.05-0.11), uye inogona kushandiswa semuviri unotsvedza kana kutenderera, ine huwandu hudiki hwekukweshana pakati pemapurasitiki.
(3) Mwero wekuwedzera kwekupisa wakaderera: Kana tembiricha iri pasi pe260 ° C, 1/100~1/1000 chete yesimbi ndiyo yakakura;Pakati pe300 ne600 ° C, inotangira pa1 × 10-6 kusvika 1 × 10-8/m · K-1, uye ndeimwe yezvinhu zvinozivikanwa kuti zvine mwero wekuwedzera kupisa mupurasitiki.
(4) Hunhu hwakanaka hwekuzvizora wega uye husina kunamira: chiyero chayo chekukakavadzana chinoshanduka chingangoita 0.5 (pasi pemamiriro ekuzora mvura);Nguva yekukakavadzana isingachinji inongova 2/5 yenzvimbo yekubatana pakati pesimbi nesimbi;Pamusoro payo pakanyatsotsvedzerera uye hapabatike nyore nyore kuzvinhu zvinosvibisa zvakaita seguruva nemafuta mumhepo.
(5) Haina hwema, haina hwema, uye haina chepfu.
NZIRA YEKUSARUDZAChitarisiko
1. Tarisa zvinhu zvinoshandiswa kugadzira firita yemhepo yemotokari
Bepa remhepo remhando yepamusoro rine kusimba kwakanaka uye rinodzivirira hunyoro, rine zvinhu zvefirita zvakarongwa zvakanaka, uye zvikamu zviri mukati mechikamu chekuvhara zvese zvinoshanda pakusefa. Zvisinei, zvigadzirwa zvemhepo zvemhando yepamusoro zvinoshandisa bepa refirita remhando yakaderera kuchengetedza mari.
Nzvimbo yekusefa yemafirita emhepo asina kunaka ine zvikamu zvishoma zvemafirita uye chimiro chakasununguka, izvo zvinoita kuti zviome kugara zvichipa mhedzisiro yakanaka yekusefa, zvichikonzera tsvina kupinda muinjini uye zvichikurumidzisa kumhanya kwekuvharika kwemafirita emhepo netsvina.
2. Tarisa maitiro ekuvhara zvinhu zvemhepo yemotokari
Chidimbu chekuvharira chemafirita emhepo emhando yepamusoro chinowanzogadzirwa nefuro rePU, iro rine chisimbiso chakanaka uye rinochinjika. Kana chidimbu chekuvharira chefirita yemhepo chisina kuenzana, chisina kuvharirwa zvakasimba, kana kukuvara zviri nyore pasi pesimba rekunze, zvinogona kuratidza kuti chigadzirwa chemhando yepasi kana chenhema.
Pamusoro pezvo, kana muganhu uri pakati pechinhu chinovhara firita yemhepo nezvinhu zvinosefa usina kurongeka, zvinowanzo ratidza kuti maitiro ekugadzira firita iyi yemhepo haasi ekare uye haana kutarisirwa kwemhando yepamusoro, zvichiita kuti zviome kuona kuti chigadzirwa chakanaka.
