    Ukuphatha kunye nokugcina

    Iingcebiso malunga nokuphathwa ngokukhuselekileyo
    Sebenzisa izixhobo zokuzikhusela.
    Musa ukutya, ukusela okanye ukutshaya ngexesha lokusebenzisa.
    Ukufudumala kakhulu kwe-quaternary amine kwixesha elide elingaphezulu kwe-180 F (82.22 C) kunokubangela ukuba imveliso yonakale.
    Iindawo zokuhlamba ezingxamisekileyo kunye neendawo zokuhlamba amehlo kufuneka zibe lula ukuzifikelela.
    Landela imithetho yokusebenza esekwe yimigaqo karhulumente.
    Sebenzisa kuphela kwiindawo ezinomoya ococekileyo.
    Kuphephe ukudibana namehlo.
    Kuphephe ukuphefumla umphunga kunye/okanye ii-aerosols.

    Amanyathelo ococeko
    Nika iindawo zokuhlamba amehlo ezifikelelekayo kunye neeshawa zokhuseleko.

    Amanyathelo okukhusela ngokubanzi
    Lahla izinto zesikhumba ezingcolisiweyo.
    Hlamba izandla ekupheleni komsebenzi ngamnye nangaphambi kokuba utye, utshaye okanye usebenzise indlu yangasese.

    Ulwazi Lokugcina
    Musa ukugcina kufutshane nee-asidi.
    Gcina kude ne-alkalis.

    FAQ

    Ndifuna ukuvelisa i-PIR foam enokugungqa kancinci kakhulu. Ngaba i-TMR-2 ingcono kune-TMR-30?

    Ewe, i-TMR-2 (ityuwa ye-ammonium ye-quaternary) ayiniki mandla okunyibilika kakhulu ngelixa isabonelela ngokusebenza kakuhle komlilo.

    Ifoam yam eqinileyo ayinamatheli kakuhle kwifoyile ye-aluminiyam. Inganceda njani i-TMR-2?

    Indalo yayo ye-polar iphucula ukunamathela kwiindawo zesinyithi, inciphisa ukuqhekeka.

    Ingakanani inqanaba eliqhelekileyo lokusetyenziswa kwe-TMR-2 kwi-laminate ye-PIR eqhubekayo?

    0.4–1.2 phr kuxhomekeke kumxholo we-trimer oyifunayo kunye nesantya somgca.

    Ngaba i-TMR-2 ingasetyenziswa kunye ne-potassium octoate?

    Ewe, zisebenza ngokubambisana. Umxube we-TMR-2 (0.5 phr) kunye ne-potassium octoate (0.5 phr) unika i-trimerization entle kakhulu kwaye ayinakuqhekeka.

    Ifoam yam ye-PIR inesakhiwo seseli esirhabaxa nesingafaniyo. Ndingasiphucula njani?

    Yongeza i-TMR-2 kancinci kwaye unciphise ubungakanani be-catalyst yejeli enamandla ukuvumela ukukhula kwamaqamza okulawulwa ngakumbi.

    Ingaba i-TMR-2 iyanyibilika emanzini? Oko kuyichaphazela njani indlela ecutshungulwa ngayo?

    Ewe, iyanyibilika emanzini, kodwa gcina amanzi kude nefomyula kuba iya kuphendula kwi-isocyanate.

    Ngaba i-TMR-2 ibangela ukugqwala kwiintloko ezixubayo?

    Hayi, ayidli kakhulu kune-alkali metal catalysts.

    Iphaneli yam yefoam iyasilela kuvavanyo lokwaluphala kobushushu begumbi (utshintsho lobukhulu >1%). Ngaba i-TMR-2 ingalulungisa?

    Ewe, umxholo ophezulu we-trimer ovela kwi-TMR-2 uphucula kakhulu uzinzo lobukhulu.

    Ingakanani ixesha lokugcinwa komxube we-polyol oqulethe i-TMR-2?

    Iinyanga ezi-3–6, kodwa musa ukuthabatha umswakama kuba i-TMR-2 ayibonakali kakuhle.

    Ngaba i-TMR-2 ingasetyenziswa ekugqumeni imibhobho egalelwa endaweni yayo?

    Ewe, inika ukuhamba kakuhle kunye nokungaguquguquki kakuhle, ifanelekile kwiipayipi ezinkulu.
