Kushandisa Zvigadzirwa
HQEE ndeye symmetrical inonhuhwirira diol cheni extender. Inogona kuvandudza kusimba, kuoma, kusimba zvivakwa kune MDI-polyurethane elastomers. HQEE/MDI iPU elastomer akatevedzana akafanana MOCA/TDI. Zvigadzirwa zvakapedzwa se: oiri tsime zvisimbiso, forklift matayi, conveyor bhandi, hydraulic cylinder seals uye zvimwe zvakawanda zvigadzirwa zvePU.
LCU elastomers inoda maviri emisimboti zvikamu: prepolymer inogumiswa neanoshanda isocyanate mapoka uye difunctional inoshanda hydrogen-terminated cheni extender. Prepolymer chigadzirwa chinoenderana nekuita kwepolyester kana polyether ine isocyanate (TDI, MDI, ADI). Iyo chain extender inowanzova pfupi chain ye diamine kana diol. MDI prepolymers inowanzowedzerwa ne diols.
Package Uye Kuchengeta
Package:
25kg/carton dhiramu kana sezvinodiwa zvako.
Remark: Kemikari kuumbwa uye saizi inogona kuvandudzwa nezvinodiwa nevatengi
Kuchengeta:
Ramba wakavharwa zvakasimba. HQEE ndeye hygroscopic uye inoshandura ruvara pasi pezuva. Ramba wakavharwa zvakasimba uye chengeta munzvimbo ine mhepo. Ramba kure nehunyoro nechiedza chezuva
Safety Protection
Chengetedzo yekubata zvakachengeteka
Kubata munzvimbo ine mhepo yakanaka. Pfeka zvipfeko zvinodzivirira zvakakodzera. Dzivisa kusangana neganda nemaziso. Dzivisa kuumbwa kweguruva uye aerosols. Shandisa midziyo isiri-sparking. Dzivirira moto unokonzerwa ne electrostatic discharge steam.
