Kushandiswa
4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA) chinhu chinowanikwa mumakemikari, uye nzira huru dzekushandisa kwayo ndeidzi:
- Kugadzirwa kwezvinhu zvePolyurethane: MOCA chinhu chakakosha chekuwedzera cheni ye polyurethane elastomers. Mukugadzira polyurethane, isocyanate prepolymers inofanira kuita ne chain extenders kuti igadzire high - molecular - weight polyurethane polymers. MOCA ine reactivity yakakwira ne isocyanates, iyo inogona kuwedzera zvinobudirira polyurethane molecular chain uye kuvandudza kuomarara, simba, kuramba kupfeka, kuramba kubvaruka nezvimwe zvinhu zvechinhu chacho. Inowanzoshandiswa mukugadzira zvigadzirwa zve polyurethane elastomer zvine mutoro wakakwira, zvakaita se sieve plates, rabha rollers, seals, nezvimwewo zvinoshandiswa mumaindasitiri akadai semigodhi, metallurgy, uye peturu. Zvigadzirwa izvi zvinofanirwa kuva ne resistance yakanaka yekupfeka uye hunhu hwemakanika.
- Mushonga weEpoxy Resins: MOCA inogona kushandiswa semushonga wekupisa maepoxy resins. Inosangana nemaepoxy resins kuti igadzire network ine mativi matatu, nokudaro ichirapa maepoxy resins. Maepoxy resins akacheneswa ane hunhu hwakanaka hwemuchina, anodzivirira ngura yemakemikari, uye anodzivirira kupisa. Inowanzoshandiswa mukugadzira mamwe maepoxy composites ane zvinodiwa zvepamusoro-soro, senge muminda yezvinhu zvemagetsi zvekuisa muhari uye zvekuisa pasi. Zvinhu zvemagetsi zvekuisa muhari zvinoda kuchengetedza zvikamu zvemagetsi zvemukati kubva kunharaunda yekunze. Epoxy resin yakacheneswa nekubatanidzwa kweMOCA inogona kupa chisimbiso chakanaka uye dziviriro yemuchina. Maepoxy floor coatings anofanira kuva nehunhu hwakadai sekudzivirira kupfeka uye kuramba ngura kuti asvike pazvinodiwa munzvimbo dzakadai semaworkshop emaindasitiri nenzvimbo dzekupaka mota.
Kurongedza uye Kutumira
25KG/bhegi kana zvichienderana nezvinodiwa nevatengi.
Kutumira: Mhando 6.1 dzezvinhu zvine njodzi uye zvinogona kutumirwa negungwa.
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
