I tua atu：Ka taea e te kamupene te rangahau me te whakawhanake i nga hua hou i runga i te hiahia motuhake o o taatau kiritaki.

Āhuatanga:Ko te RFE polyisocyanate he hononga honohono tino whai hua mo te whakapiri i runga i te polyurethane, te rapa taiao me te rapa Synthesis. He pai hoki te RFE polyisocyanate mo te whakapai ake i te whakapiringa o nga rawa rapa. Ka taea te whakamahi hei whakawhiti whakawhiti hei utu mo Bayer's Desmodur RFE.

Whakamahinga: Me whakamahi te whakapiri-waahanga e rua me te waa e tika ana i muri i te whakaurunga o te RFE. 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 wa e tika ana, he maha nga haora, kotahi ra mahi ranei, ka uaua ake te whakapiri

ka mahi, ka tere ake te pokey. Ka mutu, ka waiho hei tiēre korekore. 100 te whakapiri kounga, Hydroxyl polyurethane ( Polyurethane account mo a tawhio noa 20%), RFE mahi 4-7. rapa Chloroprene ( Rubber account for around 20%) , RFE e 4-7.

Rokiroki: Tena koa penapena ki roto i te ipu hiri taketake i raro i te 23℃, ka taea te pupuri i nga hua mo te ono marama. Ko nga hua raupapa Crosslinker katoa e tino pa ana ki te makuku; ka puta mai te hauhaa waro me te Urea karekau ki te tauhohenga ki te wai. Mena ka puta ki te hau, ki te marama ranei, ka tere ake nga huringa tae o nga hua, Engari kaore e pa te mahi mahi.
