    Ukuphatha kunye nokugcina

    1. Amanyathelo okuzikhusela xa uphatha izinto ngokukhuselekileyo
    Icebiso malunga nokuphatha ngokukhuselekileyo: Musa ukuphefumla uthuli. Nxiba impahla yokuzikhusela efanelekileyo kunye neeglavu.
    Ingcebiso malunga nokukhusela umlilo nokuqhuma: Imveliso ngokwayo ayitshi. Amanyathelo aqhelekileyo okukhusela umlilo.
    Amanyathelo ococeko: Susa kwaye uhlambe impahla engcolileyo ngaphambi kokuba uphinde uyisebenzise. Hlamba izandla ngaphambi kokuba uphumle nasekupheleni kosuku lomsebenzi.

    2. Iimeko zokugcina ngokukhuselekileyo, kuquka naziphi na izinto ezingahambelaniyo
    Ulwazi oluthe vetshe malunga neemeko zokugcina: Gcina kwisikhongozeli sokuqala. Gcina izikhongozeli zivalwe kakuhle kwindawo eyomileyo, epholileyo nengena umoya kakuhle.

    FAQ

    Ndenza i-PIR rigid foam ukuze ndigqume umbhobho kwaye ndifuna i-trimerization catalyst ekhawulezayo kakhulu. Ngaba i-K 2097 ifanelekile?

    Ewe, i-potassium acetate yeyona nto ikhawulezayo ekulungiseni i-trimer; sebenzisa i-0.3–1.0 phr ukuze unyangeke ngokukhawuleza kwaye ube nomxholo ophezulu we-trimer.

    Ibhodi yam ye-PIR eqhubekayo inengxaki enkulu yokugungqa. Ndingayisebenzisa njani i-2097 ukuyinciphisa?

    Hlanganisa i-2097 kunye ne-trimer catalyst ebuthathaka efana ne-K 15 (umlinganiselo we-1:1) kwaye wongeze inani elincinci le-gel catalyst.

    Yeyiphi i-solvent esetyenziswa kwi-MOFAN 2097?

    Ngokwesiqhelo isisombululo se-diol (DPG okanye DEG); uxinaniso olujikeleze i-35–50% ye-potassium acetate esebenzayo.

    Ngaba i-2097 ingasetyenziswa ekugqumeni ifriji egalelwayo?

    Ewe, kodwa impendulo ekhawulezayo ifuna ukuxubana koxinzelelo oluphezulu; lungisa ukuya kwi-0.2–0.4 phr.

    Igwebu lam alinamanzi kakuhle kwisikhunta esintsonkothileyo. Ungayicothisa njani i-K 2097?

    Sebenzisa i-catalyst ye-trimer efihlakeleyo okanye udibanise ne-K 15; nciphisa ne-isocyanate index ukuya kwi-250–300.

    Ngaba i-MOFAN 2097 iyakonakalisa intsimbi engagqwaliyo?

    Kancinci; sebenzisa intsimbi engagqwaliyo engama-316L ukuze unxibelelane nayo ixesha elide; hlambulula izixhobo emva kokuveliswa.

    Ingakanani ixesha lokuphelelwa kwesisombululo se-K 2097?

    Ihlala iinyanga ezili-12 kwisikhongozeli esivaliweyo sokuqala; kuphephe ukufunxwa komswakama.

    Ngaba i-K 2097 ibangela ukutshintsha kombala kwiibhodi zefoam ezimhlophe?

    Hayi, iityuwa zepotassium azibangeli tyheli; ukutshintsha kombala kudla ngokubangelwa yi-isocyanate oxidation.

    Ndingayisebenzisa i-K 2097 kunye nee-catalysts ze-amine trimer ezifana ne-TMR-30?

    Ewe, ukusebenzisana kuphucula ukubambezeleka kwelangatye kwaye kunciphisa ukubuthathaka; zama i-0.3 phr K 2097 + 0.5 phr TMR-30.

    Ithini idosi eqhelekileyo yentlanganiso yebhodi ye-PIR ye-ASTM E84 Class A?

    0.8–1.2 phr (isiseko esisebenzayo) idityaniswe ne-flame retardant efana ne-TCPP.
