Te utu pai rawa atu Desmodur RE / Isocyanate RE mō ngā piripiri CAS 2422-91-5
He kaihopu hononga-whakawhiti kaha rawa tā mātou RE, e whakamahia ana i roto i ngā piripiri i hangaia mai i te polyurethane hydroxyl, te rapa tūturu, te rapa hangai rānei. He tino kaha te here i roto i te rapa me te kāpene ka taea te whakamahi ki te kapia, te antioxidant, te kaihopu kirihou, te tairongo-pēhanga me ētahi atu. Ka taea te whakamahi hei hononga-whakawhiti hei utu mō te Desmodur RE a BAYER.

Ko tā mātou RE, e kiia ana ko te TTI, he otinga kei roto ko te 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate me te 72.5% ethyl acetate. He mea whakaora/whakawhitiwhiti mō te piripiri i ahu mai i te polyurethane hydroxyl, ngā rapa taiao me ngā rapa hangai, he mea tino pai mō te hono i ngā rauemi rapa. He mea whakamahi whānuitia hoki mō te hono i ngā konganuku ki te rapa. Hei tāpiri, ka taea te whakamahi i te RE ki te kapia, te antioxidant, te plasticizer, me ētahi atu. I roto i te mara piripiri, ka whakamahia te RE hei kaihoko whakawhiti i runga i te piripiri neoprene me/ranei te piripiri polyurethane hydroxyl i roto i ngā wāhi hu. I te nuinga o te wā, mō te whakaora i te piripiri o te 100 wāhanga taumaha (pbw) i runga i te nui o te RE e taunakitia ana o te 4-7 pbw. Ko te roa o te ora o te piripiri whakauru he tata ki te hāora.
Me whakamahi te piripiri wāhanga-rua i roto i te wā e tika ana i muri i te whakaurunga o te RE. Ko te roa o te wā e tika ana ehara i te mea e pā ana ki te nui o te polymer i roto i te piripiri, engari me ētahi atu wāhanga e tika ana (pēnei i te kapia, te ārai-hāora, te plasticizer, te whakarewa, me ētahi atu). Ina tata ki te wā e tika ana, he torutoru hāora, he rā mahi rānei, ka uaua ake te whakamahi i te piripiri, ā, ka piki wawe te matotoru. Hei whakamutunga, ka huri hei tiēre kore e taea te hoki. Piripiri kounga 100, Hydroxyl polyurethane (tata ki te 20%), RE horopeta 4-7. Rapa chloroprene (tata ki te 20%), E 4-7 ngā mahi a tā mātou RE.
Te tākai:
750g/pounamu, 20 ngā pounamu i roto i te kātene kotahi, 24, 30 rānei ngā kātene i roto i te papa kotahi;
20kg/pahu, 18 pahu, 27 pahu rānei i roto i te kotahi papa;
55kg/pahu, 8, 12 rānei ngā pahu i roto i te kotahi papa;
180kg/pahu, 4 ngā pahu i roto i te papa kotahi
Rokiroki:
Me rongoa ki roto i te ipu hiri taketake i raro i te 23℃, ka taea te pupuri i ngā hua mō te 12 marama. He tino pāngia e te hau; ka puta he hauhā waro me te urea kore-rewa i te tauhohenga ki te wai. Ki te pāngia e te hau, e te mārama rānei, ka tere ake te hurihanga o te tae, engari kāore e pāngia te mahi a te tinana.
