Ngā RFQ
He aha te mea i hangaia ai te whakamarumaru paipa rapa nitrile?
Ko te whakamarumaru paipa rapa nitrile he mea hanga ki te rapa nitrile, ki te Buna R rānei, he elastomer e whakamahia whānuitia ana. Ko te rapa nitrile he mea hanga mai i ngā copolymers kāore i te mākū o ngā monomers acrylonitrile me te butadiene. He rerekē ngā āhuatanga matū me ngā āhuatanga ā-tinana o te rapa nitrile i runga i te hanganga polymer.
He aha te rerekētanga i waenga i te whakamarumaru NBR/PVC me te whakamarumaru EPDM?
Kua tata ki te 70 tau te roa o te whakamahi i te rapa hei ārai i ngā pūnaha miihini i raro i te taiao (makariri) pērā i te HVAC, VRF/VRV, te pouaka whakamātao, te wai matao, te hau hauora, me ngā paipa wai matao.
Mō te whiriwhiri rauemi hanga, he mea nui te tātari me te whakataurite kia tika ai te whiriwhiri hua. Ahakoa kei te whiriwhiri koe i te rauemi whakakikorua mō te whare teitei, i te hua whakamahana rānei mō te HVAC, i te pūnaha paipa rānei, he mea nui te whakarite kia tutukihia ngā whakaritenga tono me ngā ture hanga kia whai hua ai, kia tutuki ai hoki te whakaurunga. Ka pāngia katoatia te whiriwhiri kaupapa angitu e ngā taurangi pēnei i te pāmahana, te mātotoru, te uruhanga wai, te ātete UV rānei e ngā taurangi rerekē.
I roto i te ao whakamahana miihini, he kōwhiringa a Kingflex mō te nuinga o ngā tono me ngā hiahia. Kāore i rite ki ētahi atu kaihanga whakamahana, e rua ngā rauemi whakamahana elastomeric rongonui a Kingflex mō te HVAC, te wai matao, me ngā pūnaha whakamatao e hangai ana ki te hangarau rapa nitrile butadiene (NBR) me te rapa ethylene propylene diene monomer (EPDM) e hangaia ana e ia. He ngāwari, he pūtau kati ēnei pahuka elastomeric e rua, ā, he ātete nui ki te makuku me te urunga mai o te wai. Inaa, he iti rawa te uruhanga wai, kāore e hiahiatia he aukati wai-haumanu. Waihoki, me te ātete nui ki te kohu me te putanga o te mata, he tino pai te mahi a ēnei pahuka elastomeric ki te aukati i te hanganga o te haukū o te mata.
Ngā Kaha Rerekē me ngā Whakamahinga Rerekē
Ahakoa te āhua ōrite o te NBR me te EPDM, he rerekētanga matua anō kei reira. He matū pūmua kore-kakara te NBR, engari he pūmua kakara te EPDM. Heoi anō, ka hangaia te NBR mā te whakamahi i ngā monomers acrylonitrile me te butadiene, ko te EPDM ia ka hangaia mā te whakamahi i te ethylene, propylene me te diene comonomer. Ko tētahi atu rerekētanga nui mō te whakamahinga, ko te whānuitanga pāmahana o te NBR mai i te -40F ki te 180F, ko te whānuitanga pāmahana mahi o te EPDM he whānui ake mai i te -65°F ki te 250°F.
Ko te NBR anake te elastomer tino ātete ki te hinu me te wahie. E mōhiotia ana hoki mō te pupuri i tōna pumau i ngā pāmahana iti. I tētahi atu taha, ko te EPDM he rapa ātete ki te wera, te ozone, me te UV, he kaha nui tōna ki te kume, te ātete ki te koroheketanga, me te ātete ki te paoa, ā, he iti ake te matotoru o te paowa me te whanaketanga mura toharite, inā koa i te matotoru 1-1/2 me te 2 inihi.
Ko ngā hua whakamahana pahuka pūtau rapa e rua mai i Kingflex kua whakamātauhia hei whakakapi i te muka karāhe i runga i te HVAC, te wai matao, me ngā pūnaha whakamatao (ngā paipa, ngā papu, ngā tāke, ngā ipu, me ngā porowhita) nā te mea he matū wai-kore, he hanganga pūtau-kati, me ngā ārai kohu kua hangaia ki roto.
