Nhanganyaya
Xylene diisocyanate.
Properties: TDI imvura isina ruvara kuenda kuchiedza yero ine kunhuhwirira kwakasimba. Inogona kunyungudika muorganic solvents uye inopindirana nezvakawanda organic zvinhu.
Zvishandiso: TDI inonyanya kushandiswa seyakasvibirira ye polyurethane, inogona kushandiswa kugadzira polyurethane furo, polyurethane elastomer uye coatings, adhesives, etc. TDI inoshandiswawo munzvimbo dzakadai sekugara kwemotokari, fenicha, shangu, machira uye machira emotokari. .
Nzira yekugadzirira: TDI inowanzogadzirirwa nekuita kwexylene uye ammonium bicarbonate pakupisa kwepamusoro. Mamiriro ekuita chaiwo uye sarudzo yecatalyst inogona kukanganisa kuchena uye goho rechigadzirwa.
Ruzivo Rwekuchengetedza: TDI chinhu chine njodzi chinogumbura uye chinoita ngura paganda, maziso uye nzira yekufema. Kuratidzwa kwenguva refu kana kuratidzwa kune yakawanda kunogona kukonzera kukuvara kwekufema, kusawirirana, uye kuzvimba kweganda. Paunenge uchishandisa TDI, matanho akakodzera anofanirwa kutorwa, sekupfeka maziso ekudzivirira, magirovhosi uye zvinofema. Paunenge uchichengeta uye uchibata TDI, dzivisa kusangana nenzvimbo dzemoto uye shanda munzvimbo ine mhepo inofefetera. Mukugadzirwa kwemaindasitiri uchishandisa TDI, maitiro ekuchengetedza akakodzera uye mirau inofanirwa kutevedzwa.
