Intshayelelo
Xylene diisocyanate.
Iimpawu: I-TDI lulwelo olungenambala ukuya kumthubi olukhanyayo kunye nevumba elibukhali elibukhali. Inokunyibilika kwizinyibilikisi zendalo kwaye ichaphazeleke ngezinto ezininzi eziphilayo.
Ukusetyenziswa: i-TDI isetyenziswa kakhulu njengento ekrwada ye-polyurethane, engasetyenziselwa ukuvelisa i-polyurethane foam, i-polyurethane elastomer kunye ne-coatings, i-adhesives, njl. njl. .
Indlela yokulungiselela: I-TDI ilungiswa ngokubanzi ngokusabela kwexylene kunye ne-ammonium bicarbonate kubushushu obuphezulu. Iimeko ezithile zokusabela kunye nokukhethwa kwe-catalyst kunokuchaphazela ukucoceka kunye nesivuno semveliso.
Ulwazi ngoKhuseleko: I-TDI yinto enobungozi enokucaphukisa kwaye yonakalisa ulusu, amehlo kunye nomjelo wokuphefumla. Ukuvezwa ixesha elide okanye ukuvezwa kwizixa ezikhulu kunokubangela umonakalo wokuphefumla, ukuchasana nomzimba, kunye nokudumba kolusu. Xa usebenzisa i-TDI, kufuneka kuthathwe amanyathelo okhuseleko afanelekileyo, njengokunxiba ieyewear ezikhuselayo, iiglavu kunye neziphefumli. Xa ugcina kwaye uphethe i-TDI, kunqande ukunxibelelana nemithombo yomlilo kwaye usebenze kwindawo engena umoya. Kwimveliso yemizi-mveliso esebenzisa i-TDI, iinkqubo ezifanelekileyo zokusebenza kunye nemimiselo yokhuseleko kufuneka ithotyelwe ngokungqongqo.
