Nga taonga hua me nga ahuatanga

Ko te RFE polyisocyanate he hononga whakawhiti 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 hononga whakawhiti hei utu mo te Desmodur RFE a Bayer.

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 iti noa nga haora, kotahi ra mahi ranei, ka uaua ake te mahi a te whakapiri, 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.

Te Tarapi me te Rokiroki

Mōkī: 0.75kg / pounamu, katoa 20 ipu i roto i te kotahi pouaka kātene, 180kg / oko, RĀNEI rite ki te tono kiritaki.

Tena koa rongoatia 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 whakaputa i te hauhā me te Urea karekau e whakarewahia i roto i 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.
