Kugwiritsa ntchito

Pentaerythmit imagwiritsidwa ntchito makamaka popanga mafakitale. Itha kugwiritsidwa ntchito popanga zojambula za alkyd zokutira, zomwe zimatha kusintha kuuma, komwe kumatha kusintha maluso, kukhazikika kwa filimu yokutidwa. Amagwiritsidwanso ntchito ngati zopangira za rosin zomwe zimafunikira poizoni, ma varnish ndi mapulogalamu osindikizira, ndipo amatha kugwiritsidwa ntchito pokonza mafuta, zokutira zonunkhira ndi mafuta opaka mafuta. Kuphatikiza apo, imagwiritsidwanso ntchito popanga mankhwala, mankhwala ophera tizilombo ndi zinthu zina. Molekto Molekylule ali ndi magulu anayi ofanana ndi ma hydroxymethyl ndipo ali ndi mawonekedwe apamwamba kwambiri. Chifukwa chake, nthawi zambiri imagwiritsidwa ntchito ngati chinthu chopangira pokonzekera mankhwala a polyfinucal. Kusankhidwa kumatha kutulutsa pentaerythmitol tetranrate, komwe ndi mphamvu yamphamvu; Kutulutsa kumatha kupeza pentaerythmitol triacrytola, yomwe imagwiritsidwa ntchito ngati yophimba. Itha kugwiritsidwanso ntchito ngati layala womata zomatira. Akaphatikizidwa ndi ammonium polyfuosphate, thiremescenty flamentant okhazikika imatha kupezeka. Amagwiritsidwanso ntchito ngati wothandizira wa pourerethane kuti apereke unyolo wobwera mu polyurethane.

Kutumiza ndi kutumiza

Kulongedza: 25 / kg,Mapulogalamu opangidwa ndi pulasitiki kapena matumba a Kraft kapena monga zofunikira makasitomala.

Kutumiza: Kukhala kwa mankhwala wamba komanso kumatha kupereka pa sitima, nyanja ndi mpweya.

Pitilizani ndikusunga

Moyo wa alumali: Mwezi 24 kuyambira tsiku lopanga mu phukusi lokhazikika losagwirizana ndi dzuwa louma, madzi.
Chosokoneza chosungira, kuyanika kwa kutentha kochepa, kupatulidwa ndi oxidants, ma acid.
