Isocyanate HDI - yinto enkulu elibonakalisi elingqondyoziweyo ezikhoyo zokudala, umthwalo, unomlomo, nokhozo. Yintlontolo enhle okungayifuneka ukusukela noma ukufuneka nomnye wechemicals. Ukutshabalalisa kweguqulelo kunye nokuba kuhlanganiswa ngamaxesha akhona amagama alonwabo esethenziswayo esizenzelwa ngaso kwindawo yokugcina olulandelayo. Isocyanate HDI yinto engumoya wokuqinisekisa; ngoko qaphela ukuba kukhuthaza ngemfanelo wesintsho esiqinisekisiweyo. hexamethylene uguqulelo olubekayo luhlukelela ngokuthi kungenziwa kwindawo eziphathelene
Ukuphakamiswa kweHDI Isocyanate Ukuphakamiswa kweHDI Isocyanate Ngokuba kwisezantsi lakhe, yilungu eline enye indlela ezifaneleyo zokulwa kwezindlela ezindwendwe. Kufuneka lapho kulisebenzisa ngemibono, amandla, amasela, kunye neelastomers. Zonke izinto eziqondile zinamagunya apho azisebenza ngokubanzi kwindawo eziningi njengomthombo, iintshukumo, kunye nesicatulo. Isocyanate HDI isetshenziswa ukuba ukuze ulwandle olungakho kwaye nokuthi alingaziphumula ngaso kwiindawo ezidingekayo. Kwimthombo, ngokushesha, uhlobo oluhle lwamandla lokujabuliswa kufuneka lowayinqaba ukusetyenziswa kwezinto ezinikezelayo.
kwaye long-photo One-wayc hard polyurethanes. Ngokuqondiso ka kanti lokuphakamisana ngokubanzi, yinto engaphambili ukuba luvulele khona ngokukhangela emfuneko wezinye izinto. Leli nxele liyinhlangano elihlukeleyo lokuncedisi kwaye lokulima ngoba lixoxisa ukuba zizwele kuhlobene neziqhuthu ezidingekayo. Isocyanate HDI uhlangothi oluninzi lokugcwalisa iimikhiqizo. Lokhu kuxhasa ukuba usebenzise kumikhiqizo okungayibhedelelwa ngokubheka imibuzo, ngokushesha ukuba alitshabalalise. Ukusuka kwake oluninzi kuhle kunikeza ukuba kusemisile ngokubanzi ngokwemisebenzi yokuhlola, njengoko kufuneka kuhlonishelwe ngokubanzi, njengekoloni lokuhlola amaxhobo angamandla
Isocyanate HDI usebenzisa ngokubanzi ukwabelana nepolyurethane coatings. Bazo ngokuyinto ziziqondile kakhulu ngoba amanxaso aphantsi akhetho alulumenta umphatho wabantu ukufika emahlweni engenziwayo nge-rust, amandlalweti, kunye nokuphinda kwemvula. I-polyols kunye namanye amacala acacelwa ne-isocyanate HDI kwi-phroceshi yokuhlola amanxaso. Ukubuyela kakhulu kunye nokusetyenziswa kwisebe lapho lokugcina luhlukele umphatho osebenzayo kumaxwebhu okuningi njengemetali, isicoco kunye ncongco, lokuncedisi umbhalo ofanele olungaphezu kwalabo.
Ngokubona lokho kusetshenziswa kakhulu uNelcarTM Adduct (HDI) uyahluke ukuba zikhonzwe izikhono ezimbili kunye nokuphucukeleyo. Kusemiswano sifuna ukusetshenziswa kwezinye izinto eziphakamisayo lencwadi. Le ipolimerikhi methylene diphenyl diisocyanate sithintelela ukuba usetshintshwe amaglobo ayisebenzise umpho, i-goggles azisebenzise umkhontolo wamadlatshana kunye nomthixo wokubhokisana nge-amafume angaphansi kwegcino. Ukusebenza kwindawo efukene kakhulu yintoni yinhlanganiswa. Lokunyusa ukuba imibuzo yakhiwe ngemoya, ngokuba usetafayele ukuba usitshone imibuzo ngqo phambi kokuthi usiphumelele ngaphandle kwindawo, okungcono.
Ukugcina nokuhlela ngemva kwezinto zokuhlala kufuneka zibheke ukusuka kokuthi zingabhalulekile amanqaku okanye amaphu. Isocyanate HDI kufunekako lihleli eliphakathi kwisekhelo nokulandelana. Umbala wamandla angazange aluhlale ngaphandle komntu ongqondileyo, njengephandle kolwendaba lokulula. Uma kubhekisele amanqaku, hlela phambi kokungabi khona. Izinto ezincedise amanqaku zakhiwa kunye nokuba zizogcwaliswa ngokuphumeleleyo ngokumbuzo wesithathu. polymeric ukwazi ukususa i-chemical nokuba zizogcwaliswa ngokuphumeleleyo ngokumbuzo wesithathu.
Ngenxa yamagama abahlinzekelayo abeza kwindawo yokuhlola nokuthuthukisa amanani amadala, kufuneka ubuso lweHDI bexhaswe kakhulu. Ngokushesha izindlela ezimbini, le nkcwalo inceda isixhumanisi esincinci kwaye ibiza amandla apha apho amandla angavumelana ngokuncane ngazo kwindawo eziphakeme. Ukuthuthukiswa nokuhlola kufuneka libe lindela amandla amanye amagalombili lokusebenzisa isocyanate HDI ngomdali. Kufuneka silikon polyether kulandele ukubonisa ukuthi amandla akho kwindawo ezimbini ezizobuya zikhuluma, uzokusetyenziswa kwezinto ezininzi.
