Amakristalu amhlophe noma i-powder emhlophe ekristalu, encibilika emanzini, utshwala kanye nezinye izinyibilikisi eziphilayo. Isixazululo sayo samanzi sine-acidic
I-1,2,3,4-Butanetetracarboxylic acid (BTCA) iyi-ejenti yokuqeda eqinile (DP) engena-formaldehyde. Inomsebenzi ophezulu wokusabela futhi ayinaphunga elicasulayo. Uma icutshungulwa yi-BTCA, izindwangu ezifana nekotini nesilika zingaba nezakhiwo ezifaka phakathi ukulwa nokuphela, ukucindezela okuhlala njalo nokugcina isimo futhi ziqinile.
I-BTCA ingasetshenziswa ukulungiselela izinto ze-polyimide. Lolu hlobo lwezinto lunokumelana okuhle kakhulu nokushisa, ukumelana ne-asidi, ukumelana ne-hydrocarbon kanye nezakhiwo ezinhle zokuvimbela ugesi, futhi lungasetshenziswa ukulungiselela izinto ezahlukene ze-polymer ezisebenzayo, njengezinto ezithinta ukukhanya, izinto ze-polymer zezokwelapha kanye nezinto ze-polymer membrane ezisebenzayo. Ingasetshenziswa ukulungiselela amasongo okuvimbela ugesi, izembozo zocingo kanye nezinto zokuvimbela ugesi.
Isikhwama sephepha esihlanganisiwe esingu-25kg, esiPolish - isihlahla selineni noma njengoba kudingeka kumakhasimende.
Isitoreji:
Gcina endaweni efudumele nengenawo umoya. Isikhathi sayo sokuphelelwa yisikhathi yizinyanga eziyi-12. Ingasetshenziswa uma ivuliwe
Ezokuthutha:
Gwema ukushisa okuphezulu kanye nokushiswa yilanga ngesikhathi sokuthuthwa.
