Ipakhi eFumanekayo kweChemistry: Ukwenza ukuthi Chemistry Ayikho Ngenzi umgabheni ngokuzenzakalelayo xa uvula amagunyaziso apha esiqinisekileyo lomculo. Umgabheni ayishayi ukuze uqeda 70°C Ngumgabheni obheke, ungaphumelela ukuba aphumelele kuhluke kukaPhosgene. Xa uvula umdlambo, uvumela ukuba alungiselele kakhulu kunye nokubhedelela.
Vula Isoda Esasetyenziswa: Ngoku sikhona isikhathi somvula isoda esasetyenziswa emva kokuba umdlalo wake wancane. Ichemical leyiya kuyenza ukuba akukho amanzi amahhusha esihlalene nesigunyazo, ukulandelayo lokuhlola. Umthengiso owenziwayo waye kusenzo sawo sesingcono kwisebe sokuhlola kunye nokuhlola.
Bhala ukususa i-MDI: Kufuneka uye uhlale ukususa amaninzi ngokusemva kwezilondolozi zokususwa ukusure ukuba i-MDI isosyanate yakho yikususa ngakwesentla. Lento ifuna ukubonisa ukususa kwesiphumo sasemva ngoku kwi-remedying nokuhlola i-phosgene, MDA, kunye nezinto ezazange zithathe izinkinga ngenxa yokulandelana ngephandle komdlalo wechemicals. Ukususa kulungile lapho kukho!
Ukushicilela Ukususa: Ngoku kwenziwe ukususwa, xa usetyenziswa ukuba i-MDI isosyanate yakho yikususa okanye ayikususa. Uma uvume amaningi apho, kufuneka ususe futhi ukuba ulandele umsebenzi omncane. Nguqukumbi lokuncedisi, leyo lokuhlola kunye neyiphi lokukhona.
Zingqina zakho ze-MDI isosyanate esihlaleni.
Iindlela ezifanelekayo apha ukusure ukuba uzityenza i-MDI isosyanate elikhoyo lokunceda.
Amaninzi Amakhulu: Use amaninzi amakhulu emva kwe-MDI isosyanate. Sebenzisa i-MDA efanelekayo kunye ne-phosgene. Iziphethu ezikhulu zizohlola ukuba uzityenze umdlalo olungempumelelo.
