Nga 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 te 20%), RFE e 4-7.rapa Chloroprene ( Rubber account for around 20%) , RFE e 4-7.

Te takai

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

Rokiroki

- Rokiroki i roto i te ipu Covestro hiri taketake.

- Te pāmahana rokiroki e taunaki ana: 10 - 30 °C.

- Tiakina mai i te makuku, te wera me nga mea ke.

Nga korero whanui: I te wa e kawe ana me te rokiroki i nga waahi iti,ka puta pea nga putunga tioata.

Ka rewa ano enei i te pāmahana rūma.Ko tehe tino tairongo te hua ki te makuku me te tauhohe ki te wai hei hanga warohauhā me te urea korekore.

No reira me mau tonu nga ipuhiritia.Te urunga o te wai ahakoa te ahua (nga ipu makuku, waikorewhakarewa, hau makuku) me aukati i te mea ka kore te hanga o te waroka nui ake pea te pehanga kino i roto i nga ipu.

Ko te mararatanga ki te hau me te marama/ranei ka kaha ake te paheketanga engari kare he paanga o teneinga ahuatanga tukatuka i te nuinga.
