Ngā Rerekētanga Tukatuka o te Rapa Taiao me te Rapa Hanga

Ngā Whakaaro Matua

• Ko te āputa tūturu ko te āheinga ki te whakahoki anō, ehara i te matū: ko te horapa o ngā taonga-mai8-12 ngā waeine Mooney mō te rapa maori, me te 3-5 MU mō te SBR, NBR, EPDM rāneimai i tētahi kaiwhakarato.
• Ka nekehia e te kaha matomato tō tautuhinga tapahi mā te10-30 ōrau o te tere whāngaii te inenga 0.5 mm kotahi, me te silicone i te pito puhoi.
• Te whakakorenga kiriu i-150 nekehanga Celsiuse kapi ana i ngā pūmua noa katoa nā te mea ka rere noa ngā whakawhiti karāhe mai i te -125 nekehanga ki te -20 nekehanga, engari ka memeha te uira silicone ngohengohe mā te mana hau anake.
• Ko te Silicone me te FKM e hiahia ana ki tētahi200-250 nekehanga Celsius i muri i te whakamaroketanga mō ngā haora 4-24; ka oti te hanga rapa maori i muri i te whakapakeketanga pēhi.

Ko te whakautu poto:He rerekē te tukatuka o te rapa māori me te rapa hangai i ngā teihana e whā, he nui te utu:te ōritetanga o te puranga i te wā e tukuna mai ana, te kaha matomato i te kaitapahi, te aratau rahunga o te rama i te wae whakakore, me te mea me whakaora tuarua te wāhangaKa horahia e te rapa maori ngā waeine Mooney e 8-12 i waenga i ngā rota engari ka mau tonu tōna āhua, kia whānui ake ai ngā ātete tapahi. Ka tae mai te SBR, NBR, EPDM, FKM me te silicone he ōrite ake engari he iti ake te kaha matomato, ā, he maha ngā wā ka hiahiatia he 200-250 nekehanga Celsius i muri i te whakamaroke kāore e tonoa e te NR.

Kāore he moni e ngaro i te raina whakaputa i roto i te taiwhanga matū. Ka ngaro te moni ina totoro te rīpene i raro i te roera whāngai, ina pakaru te rīpene, ina tere ake rānei te whakamaroke o te puranga i te 15 ōrau i te mea whakamutunga. E whai ana tēnei aratohu i te wāhanga mai i te whakaurunga ki te tākai, ā, e tohu ana i ngā rerekētanga anake e akiaki ana i te tautuhinga kia huri.

He aha te rerekētanga tūturu i waenga i te rapa taiao me te rapa hangai i roto i te hanga?

Ko te rerekētanga e tae atu ana ki te papa o te toa ko te āheinga ki te tāruarua, ehara i te hanganga ngota.Ko te rapa māori he cis-1,4-polyisoprene i tangohia mai i ngā rākau Hevea, ā, ka whakarōpūtia mā te paru, te pungarehu me te ihirangi pūngāwerewere. Nā te mea kāore i hangaia kia rite ki tētahi whāinga, ka whiwhi koe i te mea i puta i te wā. Ko te rapa hangai, i whakarōpūtia i raro i teISO 1629e te whānau, ka whakapūhuitia kia rite ki tētahi whakatakotoranga.

Nā te mea ka mākahia tētahi tāuru, ā, ka tohua tētahi, ka nekehia e te NR ō tautuhinga, ā, ka nekehia e te rapa hangai ō whakamārama.Ko taua rerekētanga kotahi e whakamārama ana i ngā rerekētanga mahi katoa i raro nei.

He aha te āhua o te ōritetanga o te puranga e whakatau ai i tō manawanui tapahi?

Nā te mea ko ia tawhā tapahi ka tohua e koe he whakapae matotoru. A Mīhini tapahi rīpene rapa CNCHe tika te whāngai mā te 0.1 mm pea, ā, ka kutikuti i te matotoru 0-20 mm tae atu ki te 80 whiu ia meneti, engari i te wā anake e mau ana te pakari o te matū e uru ana ki te mata e rite ana ki te tunu.

Me ngaungau te rapa maori i mua i te whakaranu, kia tae atu ai ki a koe me te hītori kutikuti e rerekē ana i ia rota. I roto i ngā rekoata taonga-roto a te kiritaki, ko ngā rota NR e horahia ana i te 8-12 wae Mooney (ML 1+4 i te 100 nekehanga Celsius) ko ngā rota SBR, NBR me EPDM e horahia ana i te 3-5 MU — ngā uara noa mai i ō mātou wheako.

Ko te horapa 8-12 MU he tata ki te 15-20 ōrau te pikinga o te pakari o te matū., he nui hei whakarerekē i te whāngai o te rīpene, te tawhiti e hoki whakamuri ai i muri i te mata, me te mea he tapawhā, he haehae rānei te mata i tapahia.

He uara noa iho ngā whika horapa mai i ō mātou wheako, ehara i te rohe o te rarangi pukapuka — tirohia ēnei ki tāu ake tirotiro whiwhinga.

Kei hea te wehenga o te rapa taiao me te rapa hangai i te tango rama?

Ko te rerekētanga kei te pehea te rahunga o te uira, ehara i te nui o te uira.He pīngore te uira rapa maori, ā, ka haehaea ki ngā aho, ka pakaru te uira SBR me te NBR, ā, he ngoikore te uira silicone ki te mirimiri atu.

Ko te makariri te whakaōrite whānui. Ka rere ngā whakawhiti karāhe mai i te -125 nekehanga Celsius mō te silicone ki te -20 nekehanga Celsius mō te FKM, nō reira hemīhini whakakore hauota waii te -150 nekehanga Celsius ka waiho katoa i raro i te pūwāhi pakarukaru. Ka taea e tā mātou waeine LN2 te pupuri i te 80 rita o te rōrahi roera (15-20 kg o ngā wāhanga iti) ā, ka huri i raro i te 8 meneti i te 20-70 RPM me te tere paahi neke atu i te 98 ōrau.

Kāore anō a Cryo i te mea taunoa. Ka puta te uira ngawari, iti te kaha o te haehae me temīhini whakaweto hau haui te tata ki te 4 kg/min o te pāpāho, nā te meaki te kore, ka utua e koe te hauota wai hei mahi i te haurua hēkona kua oti kē te pupuhiWhakahaerehia he puranga para i te -80 nekehanga Celsius i te tuatahi, ka whakaheke i te 10 nekehanga i ia wā; ko te tautuhinga mahana rawa atu e eke ana ki tāu whakaritenga mura ko te mea e penapena ana i te hauota.

Me whai huringa whakaora tuarua ngā matū hangai?

Ae, ā, ko te rapa maori kāore.Ko te whakamomona NR ka oti i roto i te mīhini perehi. Me whakamaroke i muri i te silicone me te FKM kia peia atu ai ngā mea pupuhi me te honohono katoa, ki te kore ka rere tonu te pakeke me te huinga pēhanga i muri i te whakatakotoranga o ngā wāhanga ki roto i te pouaka.

Ko te taputapu tika heoumu roera mō te whakamomona tuarua, ehara i te pēhi tuarua. Ka whakahaerehia ā mātou waeine XCJ-K600 (600 L) me XCJ-K900 (900 L) mai i te pāmahana rūma ki te 280 nekehanga Celsius i runga i te whakamahana 10.5 kW, ka nekehia te 3,000 CBM/H o te hau mā roto i te pahu waru-ā-toru kia kitea ai e ia mata te pāmahana ōrite, ā, ka whakaaetia te wā whakaora mai i te 0 ki te 99.99 hāora.

Whakanohoia te tuhinga whai muri i te whakaora ki runga i te kāri tunu kai, kaua ki roto i te mahara o te kaiwhakahaere.Ka whakarerekē te pakeketanga me te huinga pēhanga e te matapihi 4-hāora noa e neke ana ki te 6 hāora, ā, kei te wātea te parenga rua ki te pāmahana nui nā te mea ka wera te FKM i muri i te whakaora.

He aha te take e pakaru ai tō manawanui i te whakaitiiti i mua i te tapahi i tetahi mea?

Ko te mimiti haere, ko te wā i tapahia tika ai tētahi wāhanga ka huri hei wāhanga hē.Ko te whakahekenga whakaora o te 1.5-4 ōrau te tikanga me wehe te roa tapahi mā te kotahi tango i te āhua whakahekenga, kaua e whakatakotoria ki te ine tuhi.ASTM D2000ka whakatakoto i ngā akomanga pakeke me te manawanui engari kāore i te whakaheke, nō reira me ahu mai te tau i tāu ake whakamātautau.

Mēnā ka whakaitihia te rahi o te 3 ōrau, me tapahi he 51.5 mm te whānui o te gasket kua oti te 50.0 mm. Mēnā ka whakatakotoria he 50.0 mm, kua iti kē te rahi o te wāhanga i te 1.5 mm i mua i te tirotiro — he hapa tēnei e kore e kitea e te kaiwhakahaere, ā, e kore hoki e whakaaetia e te kiritaki.

Ka neke te NR i te 1.5-3 ōrau, ā, ka nui ake te mimiti puta noa i te witi i tō te taha, nā te mea ka anga whakamua ngā mekameka i te wā e mira ana. Ka neke te silicone me te FKM i te 2-4 ōrau, ā, ka nui ake te aro ki te pāmahana whakamaroke i tō te wā, nō reira ka taea e te tunu kotahi i runga i tētahi pēhi rerekē te tau ki waho o te manawanui.

Ko tēhea Ara Horoi e Taurite ana ki tēhea Polymer?

Āta whakaarohia te rahi o te horoinga kia rite ki te mata o te mea, kaua ki te mea i hangaia ai te wāhanga.Ka tae mai ngā wāhanga NR kua tauhiuhihia ki te talc, ki te kōhatu hopi rānei, kāore e mau ana i ngā wāhanga hangai, ā, ka pupuhi te NR i roto i te wai, engari kāore i te silicone.

Temīhini horoi me te whakamaroke rapaKa whakamahia e te XCJ-QXJ 600 tētahi pūwero kowiri tira 304, he 600 mm te whānui, he 1,000 mm te roa, ka taea te whakamahi i te 15-30 kg mō ia kawenga, ā, e toru ngā rōpū e ono ngā wāhanga e whakahaere ana. Ka whakamahia e ia te 20 rita wai (0.1 tāne mō ia horoinga 6-meneti) me te 2.5 kWh mō te horoinga me te whakamaroke mō te 20-meneti i te 12 kW / 380 V, me ngā pūwero hurihuri-whakamuri e kore e waiho he wāhi matapo.

Mō te NR, whakamahia te horoinga poto rawa e whakakore ana i te puehu, nā te mea ka pupuhi te wāhanga i muri i tō tirotiro i te roa o te rumaki. Mō te silicone, ka whiwhi te wāhanga tāpiri i tōna tūranga: ka waiho e te horoinga wai anake he kiriata ka puta ake i muri mai hei pakaru hononga i runga i te raina a te kiritaki.

Me pēhea te whakarite anō i tētahi raina mō tētahi wāhi hou?

Me whai anō i ngā kaupae e rima, kaua hoki e pekehia te tuatahi.Ko te nuinga o ngā whakawhiti rauemi i rahua ka rahua nā te mea kāore i tuhia he pūtake taketake, nō reira kāore e taea e tetahi te whakaatu he aha te mea i rerekē.

1. Whakatiohia te tauwhāititanga e haere mai ana.Tuhia te matotoru o Mooney, te mārō, te taumaha motuhake me te tau o ngā rota mō ngā rota e toru i mua i te pā atu ki tētahi tautuhinga.
2. Tapahia anō te tuhinga tuatahi i ngā tere whāngai e toru.Puritia te mea puhoi rawa e mau ana te manawanui, nā te mea ko te tere tāpiri i runga i te matū iti-kaha matomato ka hoko noa i ngā para.
3. Kimihia te matapihi pakarukaru i runga i te para.Tīmata i te -80 nekehanga Celsius ka heke iho i te 10 nekehanga kia pakaru ra ano te uira, kaua e haehae.
4. Tātaihia anō te roa tapahi mai i te whakaitinga i inehia.Inehia kia rima ngā wāhanga i roto i ngā hāora 24 i muri i te whakamaroke, kaua rawa i taua rā anō, nā te mea ka oti te nuinga o te mimiti i taua wā tonu.
5. Tuhia te tunu i muri i te whakamaroke ki te kaiwhakahaere.Te tere piki, te pāmahana pupuri, te wā pupuri me te tere whakamatao, ngā mea e whā, kaua ko te pūwāhi tautuhi anake.

Whakatau: Ko ēhea Rauemi hei Whakapūmau i te Whakamahinga?

Whakaritea ngā rauemi ka taea e tō tirotiro te whakahaere.Mā te matū hangai me te 3 MU o te horapa ka taea e koe te whakahaere i ngā taunga pakari ake me te iti ake o ngā tirotiro tuhinga tuatahi, he mea nui ake i tētahi āhuatanga ā-tinana kotahi. Ka whiwhi te NR i tōna tūranga i te mea he nui ake te hiranga o te manawanui me te kaha haehae i te auautanga - kātahi ka hokona e koe te manawanui me ngā tere whāngai puhoi ake me ngā horoinga poto ake.

Ahakoa te whānau e whakahaerehia ana e koe, kei roto i te mīhini ngā tautuhinga, ehara i te polymer. Tukuna mai tō matū, tō ine me tō whakatakotoranga rama, ā, ka taurite mātou i tētahite whakakorengate tapahi rānei i te tatūnga ki reira.
