    Tsananguro

    MOFAN TMR-2 imhando ye tertiary amine catalyst inoshandiswa kukurudzira polyisocyanurate reaction (trimerization reaction), Inopa chimiro chakafanana uye chinodzorwa chekukwira kana tichienzanisa nema catalysts akavakirwa pa potassium. Inoshandiswa mukushandiswa kwefuro rakasimba uko kunodiwa kuti kuyerera kuve nani. MOFAN TMR-2 inogona zvakare kushandiswa mukushandiswa kwefuro rakagadzirwa nenzira inochinjika yekurapa kumashure.

    Kushandiswa

    MOFAN TMR-2 inoshandiswa pafiriji, freezer, polyurethane continuous panel, pombi insulation nezvimwewo.

    Mibvunzo Inowanzo bvunzwa

    Ndinoda kugadzira furo rePIR risina kupwanyika zvakanyanya. TMR-2 iri nani pane TMR-30 here?

    Ehe, TMR-2 (munyu we quaternary ammonium) hainyanyi kupwanyika asi ichipa simba rakanaka remoto.

    Furo rangu rakaomarara harina kunamira zvakanaka pafoshoro realuminium. TMR-2 ingabatsira sei?

    Hunhu hwayo hwe polar hunovandudza kunamira pamusoro pesimbi, zvichideredza kupatsanurwa kwesimbi.

    Ndeipi nhanho yekushandiswa kweTMR-2 muPIR laminate inoenderera mberi?

    0.4–1.2 phr zvichienderana nehuwandu hwe trimer yaunoda uye kumhanya kwemutsara.

    TMR-2 inogona kushandiswa pamwe chete ne potassium octoate here?

    Ehe, zvinoshanda pamwe chete. Musanganiswa weTMR-2 (0.5 phr) nepotassium octoate (0.5 phr) unopa kucheneswa kwakanaka uye kusasimba zvakanyanya.

    Furo rangu rePIR rine chimiro chemasero chisina kuenzana uye chisina kuenzana. Ndingavandudza sei?

    Wedzera TMR-2 zvishoma uye deredza huwandu hwejeli ine simba kuti ikwanise kukura nemabubbles zvakanyanya.

    Ko TMR-2 inonyungudika mumvura here? Izvozvo zvinokanganisa sei kugadzirwa kwayo?

    Ehe, inonyungudika mumvura, asi chengetedza mvura kure nemusanganiswa wayo nekuti ichasangana ne isocyanate.

    Ko TMR-2 inokonzera ngura pamisoro inosanganisa here?

    Kwete, haina kukuvadza zvakanyanya kupfuura alkali metal catalysts.

    Panel yangu yefuro inokundikana bvunzo yekukwegura kwetembiricha yemumba (kuchinja kwehukuru >1%). TMR-2 inogona kugadzirisa here?

    Ehe, huwandu hwakawanda hwe trimer kubva kuTMR-2 hunovandudza kugadzikana kwehukuru zvakanyanya.

    Musanganiswa wepolyol une TMR-2 unogara kwenguva yakareba sei?

    Mwedzi 3–6, asi usatore hunyoro sezvo TMR-2 isinganyanyi kunyorova.

    TMR-2 inogona kushandiswa here mukudzivirira pombi dzinoiswa mukati mepombi?

    Ehe, inopa kuyerera kwakanaka uye kusachinjika kwakaderera, yakakodzera mapaipi ane dhayamita hombe.
