    Taupānga

    1.Ko te takawaenga o te fungicide azoxystrobin, azoxystrobin me te herbicide Sulfuron methyl.

    2.Kei te whakamahia hei whakakōkī, kapia crosslinker, kapia whakaora whakatere whakatere, kapia me te tāpiri rapa.

    3. Ka taea te whakamahi hei whakarewa o te acetate cellulose, te mangumangu me te poaka, te taapiri o te penehi me te hinu, te whakamaroke o te peita me te parani.

    Taonga

    Ka taea te konatunatua ki te ewaro, te etera, te chloroform, te acetone, te waikawa acetic glacial me etahi atu whakarewa pararopi, ka whakarewahia ki te wai.

    Rokiroki

    1. Kia matara atu i te mura o te ahi me nga waiora kaha, ka noho ki te wahi matao.

    2. Kare ahi me te makuku, ka rongoa i roto i te whare putunga taonga kino.
    Rokiroki me te kawe i runga i nga ture matū morearea.

    Te pumau

    1. Nga Ahuatanga: Ko te Acetylasetone he wai karekau he tae, he kowhai ranei he wai muramura. Ko te 135-137 ℃ te ira koropuke, ko te 34 ℃ te tohu hiko, ko te ira whakarewa he -23 ℃. Ko te kiato whanaunga he 0.976, a ko te taupū whakaata ko n20D1.4512. Ko te 1g o te acetylacetone ka memeha i roto i te 8g o te wai, ka uru ki te waihano, benzene, chloroform, ether, acetone me te glacial acetic acid, ka pirau ki te acetone me te waikawa acetic i roto i te rei. He ngawari ki te whakaparahako ina pa ana ki te wera nui, te mura o te ahi me nga waiora kaha. Kare e tau i roto i te wai, ka ngawari te whakamaroke ki te waikawa ahetiki me te acetone.

    2. Tikanga paitini. Ka whakapouri i te kiri me nga kiri mucous. Ka noho te tinana tangata mo te wa roa i raro i te (150~300)*10-6, ka kino. Ka puta nga tohu penei i te mahunga, te nausea, te ruaki, te mangere, me te puhoi, engari ka pa ki te 75*10-6 te kukū. Kaore he kino. Ko te hanga me tango i te taputapu hiri korehau. Me whakakaha ake te hau ki te waahi mahi hei whakaiti i te rere, te turuturu, te maturuturu me te turuturu. Mena ka paihana, waiho i te waahi ka taea te hau hou. Me mau nga kaimahi i nga taputapu whakamarumaru me te whakahaere i nga tirotiro mate mahi.
