TGIC m'malo mwa Chemistries mu zokutira ufa-Hydroxyalkylamide (HAA)
Hydroxyalkylamide(HAA) TGIC Replacement Chemistries Popeza tsogolo la TGIC silikudziwika, opanga akufufuza yofanana nayo. Mankhwala a HAA monga Primid XL-552, opangidwa ndi odziwika ndi Rohm ndi Haas, adayambitsidwa.

Zinthu zina zofunika pakuwonongeka kwa zokutira za polyester
Kuwonongeka kwa polyester kumakhudzidwa ndi kuwala kwa dzuwa, zosakaniza za photocatalytic, madzi ndi chinyezi, mankhwala, mpweya, ozoni, kutentha, kuphulika, kupsyinjika kwamkati ndi kunja, ndi kutayika kwa pigment. Chofunika kwambiri pakuwonongeka kwa zokutira: chinyezi, kutentha, makutidwe ndi okosijeni, ma radiation a UV. Moisture Hydrolysis imachitika pamene pulasitiki imadziwikiratu m'madzi kapena chinyezi. Izi zimachititsa kuti mankhwala azitha kukhala chifukwa chachikulu cha kuwonongeka kwa ma polima a condensation monga polyesters, kumene gulu la ester.Werengani zambiri …
Zofunikira pakupaka ufa pakuthirira kotentha koviika
Mafotokozedwe otsatirawa akulimbikitsidwa: Gwiritsani ntchito zinc phosphate pretreatment ngati kumamatira kwambiri kumafunika. Pamwamba payenera kukhala paukhondo. Zinc phosphate ilibe zotsukira ndipo sizichotsa mafuta kapena nthaka. Gwiritsani ntchito iron phosphate ngati ntchito yokhazikika ikufunika. Iron phosphate imakhala ndi zotsukira pang'ono ndipo imachotsa kuipitsidwa pang'ono pamtunda. Zogwiritsidwa ntchito bwino pazinthu zopangira malata. Pre-kutentha ntchito isanayambe ntchito ufa.
