Nga hua me nga ahuatanga

Ko ta tatou RE, e kiia ana ko TTI, he otinga kei roto 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate me te 72.5% ethyl acetate.He kaihoko whakaora/whakawhitiwhiti mo te whakapiri i runga i te polyurethane hydroxyl, rapa maaori me te rapa waihanga, he pai rawa mo te hono i nga rawa rapa.Kei te whakamahia whānuitia hoki mo te hono konganuku ki te rapa.I tua atu, ka taea te whakamahi RE i runga i te kapia, te antioxidant, te plasticizer, me etahi atu. I roto i te waahi whakapiri, ka whakamahia te RE hei kaihoko whakawhiti i runga i te whakapiri neoprene me te p hydroxyl polyurethane whakapiri i nga waahi hu.Ko te tikanga, mo te rongoa i te whakapiri o te 100 nga wahanga ma te taumaha (pbw) i runga i te nui o te 4-7 pbw RE.Ko te ora o te kohua o te whakapiri whakauru he tata ki nga haora.

Taupānga

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 wa 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 kapia, te antioxygen, te plasticizer, te whakarewa, me etahi atu. Ina tata ki te waa e tika ana, ko te nuinga o nga haora, kotahi ra mahi ranei, te whakapiri. ka uaua ake te whakahaere, ka tere kake ake te pokey Ka mutu, ka noho hei tiēre e kore e taea te huri. , To tatou RE mahi 4-7.
