    Nga hua me nga ahuatanga

    Ko RE he kaihoko whakawhiti-whakawhiti tino kaha, Ka whakamahia i roto i nga whakapiri i hangaia e te hydroxyl polyurethane, rapa taiao, rapa waihanga ranei,

    He pai te hononga te kaha o te rapa me te kaa ka whakamahia ki te kapia, antioxidant, kaihoko kirihou, pehanga-tairongo etc.

    Ka taea te whakamahi hei hononga whakawhiti hei utu mo te BAYER's Desmodur RE

    Whakamahinga

    Me whakamahi te whakapiri-waahanga e rua i roto i te waa e tika ana i muri i te whakaurunga ki roto RE.

    Ko te roa o te waa e tika ana ehara i te mea e pa ana ki te ihirangi polymer o te whakapiri, engari ano hoki etahi atu waahanga e tika ana (penei i te resin, antioxygen, plasticizer, solvent, etc.

    Ka tata ki te waa e tika ana, he maha nga haora, kotahi ra mahi ranei, ka uaua ake te mahi a te whakapiri, ka tere te piki o te pokey.

    Ka mutu, ka waiho hei tiēre korekore.100 te whakapiri kounga, Hydroxyl polyurethane (Polyurethane kaute mo te 20%), RE horopeta 4-7.rapa Chloroprene (Rubber account for around 20%), RE e 4-7.

    RE 2

    Rokiroki

    Tena koa rongoatia ki roto i te ipu hiri taketake i raro i te 23 ℃, ka taea te pupuri i nga hua mo te 12 marama.

    He tino tairongo ki te mosture;ka puta te hauhā me te Urea karekau ki te tauhohenga ki te wai.

    Mena ka pa atu ki te hau, ki te marama ranei, ka tere ake nga huringa tae, engari kaore e pa te mahi.

    Mōkī

    750 g / pounamu ranei 50 kg / drum ranei 180 kg / drum ranei i runga i nga whakaritenga a te kiritaki.
