    Ukuphatha nokugcina

    1. Izinyathelo zokuphepha zokuphatha ngokuphephile
    Iseluleko ngokuphatha ngokuphephile: Ungaphefumuli uthuli. Gqoka izingubo zokuzivikela ezifanele kanye namagilavu.
    Iseluleko ngokuvikela umlilo nokuqhuma: Umkhiqizo ngokwawo awushi. Izindlela ezijwayelekile zokuvikela umlilo.
    Izindlela zokuhlanzeka: Susa futhi ugeze izingubo ezingcolile ngaphambi kokusebenzisa kabusha. Geza izandla ngaphambi kwekhefu nasekupheleni kosuku lomsebenzi.

    2. Izimo zokugcina okuphephile, okuhlanganisa noma yikuphi ukungahambisani
    Ulwazi olwengeziwe mayelana nezimo zokugcina: Gcina esitsheni sokuqala. Gcina izitsha zivaliwe kahle endaweni eyomile, epholile futhi enomoya omuhle.

    Imibuzo Evame Ukubuzwa

    Ngenza i-PIR rigid foam yokuvikela amapayipi futhi ngidinga i-trimerization catalyst esheshayo kakhulu. Ingabe i-K 2097 iyafaneleka?

    Yebo, i-potassium acetate iyisihluthulelo esisheshayo se-trimer; sebenzisa i-0.3–1.0 phr ukuze uphulukise ngokushesha futhi ube nokuqukethwe okuphezulu kwe-trimer.

    Ibhodi lami le-PIR eliqhubekayo linenkinga enkulu yokugobeka. Ngingayisebenzisa kanjani i-2097 ukuze ngiyinciphise?

    Hlanganisa i-2097 ne-trimer catalyst ebuthakathaka njenge-K 15 (isilinganiso esingu-1:1) bese ufaka inani elincane le-gel catalyst.

    Yisiphi isinyibilikisi esisetshenziswa ku-MOFAN 2097?

    Ngokuvamile isixazululo se-diol (DPG noma DEG); ukuhlushwa okucishe kube ngu-35–50% we-potassium acetate esebenzayo.

    Ingabe i-2097 ingasetshenziswa ekufakweni kwe-insulation esiqandisini?

    Yebo, kodwa ukusabela okusheshayo kudinga ukuxubana kokucindezela okuphezulu; lungisa ku-0.2–0.4 phr.

    Igwebu lami alikwazi ukugeleza kahle esikhumbeni esiyinkimbinkimbi. Ungalinciphisa kanjani ijubane le-K 2097?

    Sebenzisa i-catalyst ye-trimer efihliwe noma uhlanganise ne-K 15; futhi wehlise i-isocyanate index ibe ngu-250–300.

    Ingabe i-MOFAN 2097 iyagqwala ensimbini engagqwali?

    Kancane; sebenzisa insimbi engagqwali engu-316L ukuze uthinte isikhathi eside; hlanza imishini ngemva kokukhiqiza.

    Ingakanani isikhathi sokuphelelwa yisikhathi sesisombululo se-K 2097?

    Izinyanga ezingu-12 esitsheni sokuqala esivaliwe; gwema ukumuncwa komswakama.

    Ingabe i-K 2097 ibangela ukushintsha kombala emabhodini e-foam anombala omhlophe?

    Cha, usawoti we-potassium awubangeli ukuphuzi; ukushintsha kombala ngokuvamile kuvela ekushiseni kwe-isocyanate.

    Ngingayisebenzisa yini i-K 2097 kanye nama-catalyst e-amine trimer afana ne-TMR-30?

    Yebo, ukusebenzisana kuthuthukisa ukubambezeleka komlilo futhi kunciphisa ukuphuka; zama i-0.3 phr K 2097 + 0.5 phr TMR-30.

    Iyini isilinganiso esijwayelekile somhlangano webhodi le-PIR le-ASTM E84 Class A?

    0.8–1.2 phr (isisekelo esisebenzayo) kuhlanganiswe ne-flame retardant efana ne-TCPP.
