Mutengo wakanakisisa Desmodur RE yezvinonamira CAS 2422-91-5 Triphenylmethane -4,4`,4"-triisocyanate/ Methylidintri-p-phenylene triisocyanate
RE yedu inoshanda zvikuru mukubatanidza zvinhu, Inoshandiswa mumaglues akagadzirwa nehydroxyl polyurethane, rabha yechisikigo kana yekugadzira, ine simba rakanaka rekubatanidza zvinhu murabha uye cab inoshandiswa mu resin, antioxidant, plasticizing agent, inonzwa kumanikidzwa nezvimwewo. Inogona kushandiswa se crosslinker pachinzvimbo cheBAYER's Desmodur RE.
Ruzivo rwechigadzirwa:
Zita reKemikari: Triphenylmethane-4,4',4''-triisocyanate
Fomura yeMorekuru: C22H13N3O3
CAS: 2422-91-5
MW: 367.36
Hunhu: mugadziri
Fomura yechimiro: HC[NCO]3
Kuwanda: 1.0g/c m3, 20℃
Nzvimbo yekunyunguduka: 89℃
RE yedu, inonziwo TTI, imushonga une 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate uye 72.5% ethyl acetate. Imushonga wekurapa/crosslinker wekubatanidza wakavakirwa pa hydroxyl polyurethane, rabha dzechisikigo uye dzekugadzira, kunyanya wakanakira zvinhu zverabha zvekubatanidza. Inoshandiswawo zvakanyanya pakubatanidza simbi nerabha. Uyezve, RE inogona kushandiswa pa resin, antioxidant, plasticizer, nezvimwewo. Munzvimbo yekubatanidza, RE inoshandiswa semushonga wekubatanidza pa neoprene adhesive uye/kana p hydroxyl polyurethane adhesive munzvimbo dzeshangu. Kazhinji, yekubatanidza adhesive yezvikamu zana nehuremu (pbw) zvichibva pahuwandu hunokurudzirwa hwe 4-7 pbw RE. Hupenyu hwehari yekubatanidza adhesive hunosvika maawa.
Chinonamira chine zvikamu zviviri chinofanira kushandiswa mukati menguva inoshandiswa mushure mekuiswa muRE. Kureba kwenguva inoshandiswa hakungobatanidzwi chete nehuwandu hwepolymer hwechinonamira, asiwo nezvimwe zvikamu zvakakosha (senge resin, antioxygen, plasticizer, solvent, nezvimwewo). Kana yave pedyo nenguva yakakodzera, kazhinji maawa mashoma kana zuva rimwe chete rekushanda, chinonamira chinova chakaoma kushandisa, uye viscosity inomuka nekukurumidza. Pakupedzisira, chinova jelly isingadzoreki. Chinonamira chemhando yepamusoro che100, Hydroxyl polyurethane (Polyurethane inokwana 20%), RE dose 4-7. Chloroprene rabha (Rabha inokwana 20%), RE yedu inoita 4-7.
Kurongedza:
750g/bhodhoro, mabhodhoro makumi maviri mubhokisi rimwe, mabhokisi makumi maviri nemana kana makumi matatu mupallet rimwe chete;
20kg/dhiramu, madhiramu gumi nemasere kana madhiramu makumi maviri nemanomwe mupareti imwe chete;
55kg/dhiramu, madhiramu masere kana gumi nemaviri mupareti imwe chete;
180kg/dhiramu, madhiramu mana mupareti imwe chete
Kuchengetera:
Ndapota chengetai mubhodhoro rekutanga rakavharwa pasi pe23℃, zvigadzirwa zvinogona kuchengetedzwa zvakanaka kwemwedzi gumi nemiviri. Rinonyorova zvakanyanya; rinoburitsa carbon dioxide uye urea isinganyunguduke mumvura. Kana rikasangana nemhepo kana chiedza, rinokurumidza kuchinja ruvara, asi basa rekushandisa harizokanganisike.
