Namira RFE / DESMODUR RFE CAS 4151-51-3

Tsananguro Pfupi:

Zvinhu zviviri zvinonamira zvinofanirwa kushandiswa mukati menguva inoshanda mushure mekuisa mushure mekuisa muRFE. Kureba kwenguva inoshanda hakusi kungoenderana neye polymer zvemukati zvinonamatira, asi zvakare zvimwe zvakakosha zvikamu (Senge reisn, antioxygen, plasticizer, solvent, nezvimwe. Kana iri padyo nenguva inoshanda, kazhinji maawa mashoma kana zuva rimwe rekushanda, namira. inova yakaoma kushanda, uye viscosity inomuka nekukurumidza, Pekupedzisira, inova jelly isingachinjiki. , Yedu RFE dose 4-7.

Chitarisiko

Transpareant yero-shava mvura. Ruvara rwayo harukanganisi simba rekubatanidza.

Zvigadzirwa zvinogona kunge zvine lamellar sediment.

Chigadzirwa Chikumbiro

Zvinhu zviviri zvinonamira zvinofanirwa kushandiswa mukati menguva inoshanda mushure mekuisa mushure mekuisa muRFE. Kureba kwenguva inoshanda hakusi kungoenderana neye polymer zvemukati zvinonamatira, asi zvakare zvimwe zvakakosha zvikamu (Senge reisn, antioxygen, plasticizer, solvent, nezvimwe. Kana iri padyo nenguva inoshanda, kazhinji maawa mashoma kana zuva rimwe rekushanda, namira. inova yakaoma kushanda, uye viscosity inomuka nekukurumidza, Pekupedzisira, inova jelly isingachinjiki. , Yedu RFE dose 4-7.

Zvimwe Zvakatsanangurwa Zvakabatana

Kurongedza:

750g / bhodhoro, mabhodhoro makumi maviri mune rimwe katoni, makumi maviri nemana kana makumi matatu makatoni mune imwe nhovo;

20kg / dhiramu, 18 madhiramu kana 27 madhiramu mune imwe nhovo;

55kg / dhiramu, 8 kana gumi nemaviri madhiramu mune imwe nhovo;

180kg / dhiramu, 4 madhiramu mune imwe nhovo

Kuchengetedza:

Ndokumbirawo kuti muchengetwe muhari yepakutanga yakavharidzirwa pasi pe23 ℃, zvigadzirwa zvinogona kuchengetedzwa zvakagadzikana kwematanhatu matanhatu.

Zvese zvedu zvigadzirwa zvinoteedzana zvakanyanya nehunyoro; Ichaburitsa kabhoni dhayokisaidhi uye isingasviki urea mune inoitwa nemvura. Kana ikasangana nemhepo kana / uye nechiedza, ichakurumidzisa kushanduka kwemavara ezvigadzirwa.

Asi basa rinoshanda richakanganiswa.)

Kudzivirirwa:

Hutachiona hunhu, hunopisa zvakanyanya, hunosimudzira kumeso, kana uchifemerwa unogona kukonzeresa kurwara. Kakawanda kubata kunogona kukonzera ganda kuoma kana kupenga. Mhepo yezvigadzirwa inogona kuita kuti munhu anete uye vertigo.
