Resin Vinyl Ester: Ngā Akoranga a te 35 Tau i roto i ngā Ārai mō te Kimi Tika

Kua mahi ahau i roto i ngā mea hanga mai i te tau 1989. E toru tekau mā rima tau ahau e manawa ana i te styrene, e wera ana ōku maihao i te laminate extherming, me te mahi tahi me ngā kaiwhakarato e oati ana ki te ao me te tuku para. Mena kei te pānui koe i tēnei, me hiahia pea koekapia winira estermō tētahi mea nui. He tāke matū. He takere poti. He awa horoi. Ka kōrerotia e au taku i ako ai mō te kimi i tētahikaiwhakarato kapia vinyl ester ko wai e kore e whakakino i tāu kaupapa. He whakaaro ōku. Kāore au e whakangawari i aua whakaaro.

Kati te Whakapoauau i te Vinyl Ester me te Polyester

Reini winira esterhe whanaunga nō te epoxy. Ka tangohia e koe he angaanga epoxy ka tauhohe ki te waikawa methacrylic. Ka mutu ngā rōpū ester ki ngā pito o te mekameka anake. Koinā te pūkenga katoa o te ngota. Ko te iti o ngā rōpū ester he iti ake ngā pūwāhi whakaeke mō te waikawa me te kawakore.

He maha ngā rōpū ester o te polyester puta noa i te mekameka. Koia te take ka pakaru ai ngā tāke polyester i muri i te rima tau o te mahi matū. E rua tekau ngā tau e roa ai ngā tāke vinyl ester. Kua tangohia e au ngā pūtake e rua. Kāore i te tino kitea te rerekētanga.

Kua mātakitaki ahau i ngā kaihoko e whakakapi ana i te polyester isophthalic nā te mea "he tata rawa." Kāore i te tata rawa. He pai te kapia isophthalic. Ehara i tekapia winira ester. Mēnā i tohua e tō kiritaki te vinyl ester, ā, ka tukuna e koe te iso polyester, ka mau koe. Tekau mā rima meneti te roa o te whakamātautau taiwhanga. Kātahi ka puta tō ingoa ki te pūrongo rahunga. Kaua e pena.

He pai ake te mahi a te epoxy i te vinyl ester i runga i te pepa. I roto i te mahi, he rua te utu o te epoxy, me tunua ki roto i ngā oumu i muri i te whakamaroke, ā, ka kino ki ō kaiwhakapaipai te whakamahi.Reini winira esterhe rite tonu ngā tukanga ki te polyester. Ka taea e koe te whakatakoto ā-ringa, te rehu, te pultrude, te whakahaere i roto i te RTM. Ko te ngāwari o te tukatuka te takekapia winira esterKei te whakahaere i te mākete waikura taumata-waenga. Kei te whakahaere a Epoxy i te ao rererangi. Kei te whakahaere a Polyester i ngā mea iti te utu. Kei te whakahaere a Vinyl ester i ngā mea katoa i waenganui.

Te Kōrero Utu Kāore tetahi e hiahia ana kia kōrero pono

Anei te meakaihanga kapia vinyl esterKo te utu tūturu. Ko te utu mō te bisphenol-A vinyl ester paerewa he 2,800 ki te 3,500 ia tana. Ko te Novolac epoxy vinyl ester — te taumata pāmahana teitei — kei te 3,800 ki te 4,500. Ka tīmata te epoxy i te 4,500 ka piki ki tua atu i te 7,000. Kei raro iho i te $1,800 te Ortho polyester.

Reini winira estere tata ana ki te rua te utu i te utu o te polyester iso.

Engari i roto i te waikawa whanariki 30%, e toru ki te rima ngā wā ka roa ake te ora o te vinyl ester.

I tangohia e au ngā matua o tētahi tāke matū i tērā tau. Tekau mā rima tau e whakamahia ana. Kei te ora tonu te arai vinyl ester. Ko te tāke kotahi, ko te arai polyester tārua, ko ngā āhuatanga ratonga kotahi. Ka taea e au te wawahi i taua kapia polyester ki tōku koromatua me tōku maihao tohu.

Nō reira, ina kī mai te kaiwhakahaere hoko he nui rawa te utu mō te vinyl ester, ka pātai atu ahau i tētahi pātai. He aha te utu mō te tāke ina pakaru? Ko te horoi taiao anake e tekau ngā wā e nui ake ai te utu o te kapia. He nui ake te utu mō te kereme. He māmā noa iho te pāngarau. Kāore te iwi e hiahia ki te mahi i tēnei nā te mea he nui te nama o mua i runga i te PO.

He paikaiwhakarato kapia vinyl esterhei āwhina i a koe ki te hanga i taua tauira huringa ora. Ko te tauira kino ka whakahua noa i te utu mō ia kirokaramu ka ngaro atu.

Kaihokohoko, Kaihanga rānei — Ako ki te Kite i te Rerekētanga

Ko te haurua o ngā kamupene kei runga i ngā papaaho B2B e kī ana i a rātou anō he "kaiwhakarato kapia vinyl ester"He kaihokohoko rātou. Kāore ā rātou tauhohenga. Kāore ā rātou taiwhanga. Ka hoko mai rātou i tētahi wheketere e hoko ana i te epoxy mai i tētahi atu wheketere. Ka puta te kapia ki tō tauranga me ngā tau puranga kāore e ōrite ki te CoA. Kua heke te matotoru mā te 40%. Ka waea atu koe ki te amuamu. Kāore he tangata e whakautu mai.

Anei me pēhea te tango tere i a rātou.

Tonoa ngā whakaahua o te tauhohenga me te rā o nāianei i runga i tētahi pepa i roto i te whakaahua. Tonoa ngā putanga o ia marama i roto i ngā tana mita. Tonoa ngā CoA mai i ngā puranga e toru karapīpiti. He tinokaihanga kapia vinyl esterka whakautua tonutia ēnei pātai. Ka mea tetahi kaihokohoko "tukua ahau kia tirohia, ka hoki atu ki a koe." Mā taua rerenga kōrero koe e whakamārama i ngā mea katoa.

I toro atu ahau ki tētahi "kaihanga" i te tau 2019, he paetukutuku ataahua tāna e whakaatu ana i tētahi whare reactor parakore. I tae atu ahau ki reira. He whare putunga te whare me ngā pahu kua tohua anō. Kāore he reactor. Kāore he taiwhanga. Kotahi te tangata me tana waea. I haere atu ahau. Kāore taku hoa whakataetae i pera. I ngaro i a ia te $80,000 i tētahi puranga kino i uru ki roto i te pahu i te wā e tukuna ana. I aukatia e te "kaituku" tana nama waea.

Ngā Taonga Hiranga i te Papa Toa, Kaua i te Pukapuka Whakamārama

Kāore au e aro ki te pepa raraunga. Ko tāku e aro nui ana ko te aha ka puta ina pā te kapia ki te pokepokea ai.

Te matotoru. Mena kei runga ake i te 500 mPa·s i te 25°C, ka whawhai ō laminators ki te makuku i runga i te whatu roving. Ka whakangawarihia e rātou ki te styrene. Inaianei kua waimeha e koe te kapia. Ka heke ngā āhuatanga. Ka whakapae te kaiwhakarato i a koe mō te tāpiri styrene. Ka whakapae koe i te kaiwhakarato mō te tuku kapia matotoru. Kua kite ahau i tēnei tautohe e tupu ana i ngā wā e 100. He māmā noa te whakatika. Hokona mai i tētahikaihanga kapia vinyl estere whakahaere ana i te matotoru i waenga i te 200 me te 400 mPa·s. He rite tonu.

Te wā whakapūkara. I mahi ahau me tētahi puranga i whakapūkara i roto i ngā meneti 12 i te pāmahana toa 35°C. Tekau mā rua meneti. Kāore e taea te whakatakoto i tētahi hononga manway i roto i ngā meneti tekau mā rua. Me 25 ki te 40 meneti te wā mahi mō te mahi whakatakoto-ā-ringa tino kaha. Ko tekaiwhakarato kapia vinyl esterMe whakarerekē te mōkihi kaiwhakatairanga kia rite ki tō toa. He nui ake te cobalt naphthenate mō ngā toa matao. He iti iho mō ngā mea wera. BPO mēnā kei raro iho i te 15°C te pāmahana e whakamaroke ana koe. Mēnā kāore e taea e te kaiwhakarato te whakarerekē i te pūnaha whakamaroke, kei te hoko atu rātou i tētahi tātai pumau ki a koe, ā, e tumanako ana kia mahi koe. He whakamuri tēnā. He pai te kapia māu. Kāore koe e mahi mā te kapia.

Te pakeketanga o te Barcol. Me eke ki te 35 ki te 40 i roto i ngā hāora 24 i te pāmahana rūma. Ki te mau tonu ki te 28 i muri i ngā rā e rua, he tohu kei te hē tetahi mea. Kua hē te ōrau MEKP, kua tawhito rānei te kapia, kua pakaru rānei te kaiwhakatairanga nā te korenga o te rokiroki. Kua kite ahau i te kapia "hou" e tekau mā waru marama te pakeke nā te mea i noho ki roto i te whare putunga wera o te kaituku. Kua tīmata kē te kaiwhakatairanga ki te tauhohe i roto i te pahu. Ka puta he puhoi o te whakamaroke me ngā mata piri e kore e tino whakapakeke.

Te Wāhi i Kite ai Au i te Wini a Vinyl Ester — me te Wāhi e Moumou Moni ai te Tangata

Kua tohua e aukapia winira estermō ngā tāke rokiroki matū, ngā awa horoi, ngā takere moana, ngā paipa tanumia, me ngā kōtaha hanganga pultruded. He pai te mahi. He tino pai te mahi i roto i te ratonga waikura me ngā wāhi katoa e hiahia ana koe kia 20 tau te roa o te ora hoahoa.

Ngā tipu matū. Koinā te mea nui.Reini winira esterko te rauemi whakapuru paerewa mō te pupuri tuarua. Mena kei te hanga koe i tētahi tāke e pupuri ana i te 30% waikawa hauwai, kāore he mea kē atu e iti ake te utu e ora tonu ana. Ka kī pūmau atu ahau i tēnā.

Moana. Ka kai te wai tote i te polyester. Ka roa te ora o te vinyl ester. Ka whakamahia e ngā kaihanga poti atamai te vinyl ester mō te kiri o waho i raro i te raina wai, ā, ka huri ki te polyester mō te hanganga o roto. Ka whiwhi koe i te ārai waikura i te wāhi e hiahiatia ana. Ka penapena moni koe i te wāhi kāore e hiahiatia ana.

Engari koinei te wāhi e riri ai ahau. Kua kite ahau i ngā miihini e tohu ana i te vinyl ester mō te tāke wai i te pāmahana taiao. Wai. Mahana rūma. Ka taea e te polyester Iso te whakahaere i tēnā mō ngā tau e rua tekau i te haurua o te utu. Ka kōrero ahau ki ngā kiritaki ahakoa he iti ake te kapia e hokona ana e au. Ki te nui rawa tāu tohu, kei te moumou moni a ō kiritaki. Ā tōna wā ka kitea e rātou tēnā, ā, ka kitea he tangata e pono ana ki a rātou.

Ka Whakamatea tō Tapeke Hua e te Rokiroki

Reini winira estere 3 ki te 6 marama te roa o te oranga i te 25°C. Mā ia 10°C neke atu i tēnā ka haurua te roa o te oranga.

Kua kite ahau i ngā kaihoko e tono ana i tētahi ipu kī tonu, e tū ana i roto i tētahi whare putunga pepa whakarewa i te marama o Hūrae, ā, e miharo ana ahau he aha i whakapūmautia ai te kapia ki roto i te pahu i muri i ngā wiki e waru. Ka patua e te wera te vinyl ester. Ka tīmata te tauhohe a te kaiwhakatairanga. Ka piki ake te matotoru. I tētahi ata ka whakatuwherahia e koe tētahi pahu, ā, kua totoka.

Ki te mea ko tāukaiwhakarato kapia vinyl esterKi te tukuna mai ngā taonga mai i tāwāhi, e 3 ki te 4 wiki te roa o te oranga o ngā taonga i te wā e tukuna ana. Ka pau anō te wiki e te Tari Taake. Ka noho tō whare putunga ki runga mō te marama kotahi. E ono wiki pea te roa o te oranga o ngā taonga ina whakatuwherahia e koe te pū tuatahi.

Me tono i ngā rahinga iti ake i ngā wā katoa. Ka piki ake te utu mō ia kirokaramu. He iti ake te kapia e makahia ana e koe. I whakawhitihia e au tētahi kiritaki mai i te tuku tāke nui ki ngā putea IBC ā-marama. I heke tana para mai i te 12% ki raro iho i te 2%. I mahi te pāngarau.

Kāore ngā Tiwhikete i te Kōwhiringa

Ko te ISO 9001 te papa. Ki te mea ko tāukaihanga kapia vinyl esterkāore e mutu, mutu te kōrero.

Tukunga ki Ūropi? Me rēhita koe ki te REACH. Kāore he REACH, kāore he whakaaetanga tikanga. I mātakitaki ahau i te ipu katoa a te kiritaki e puritia ana i Rotterdam mō ngā wiki e toru. Kāore he tuhinga REACH i roto i te kapia. Ko ngā utu whakahekenga i nui ake i te uara kapia. I pōkarekare noa te kaiwhakarato.

Me whai whakaaetanga momo DNV, momo ABS rānei ngā tono moana. Me whai UL 94 V-0 ngā tohu ātete-mura. Me manatoko kei te kapi te tiwhikete i te tohu motuhake e hokona ana e koe. Kua hopukina e au ētahi kaiwhakarato e whakaatu ana i te tiwhikete UL mō tētahi atu raina hua, ā, ko te tumanako kāore au e kite. I kite ahau.

Ngā mea e kōrerotia ana e au ki ngā kiritaki hou katoa

Kimihia hekaihanga kapia vinyl estermāna e whakamātautau i ia puranga, ka tukuna atu te CoA i mua i tō pātai. Me whakautu te kaimahi rongoā i te waea ina kore e maroke tō kapia. Me ora te takai mō ngā wiki e toru i roto i te ipu. Me tae mai ngā tuhinga i mua i tō whai i a ia.

Whakamātauria te ota tuatahi. I ngā wā katoa. Kotahi ki te rima tana. Whakahaerehia mā roto i tō raina whakaputa tuturu. Ehara i te taiwhanga. Ko te taiwhanga te teka. Ko te papa o te toa e kōrero ana i te pono. Tuhia te wā o te werowero i te pāmahana o tō toa. Tirohia te whakamakuku i runga i tō whakakaha motuhake. Wāhia te wā o te tangohanga. Rapua he poka iti me ngā karu ika i runga i te mata o te koti werowero.

Kātahi ka whakatauritea te mata ki te mata o te mea kei te whakamahia e koe ināianei. Ki te tere ake te maroke o te kapia hou, ka pai ake te mākū, ā, kua ma te mata, kua kitea e koe tō kaiwhakarato. Ki te kino ake tētahi o aua mea, me rapu tonu.

Kua mahi tahi ahau mengā kaiwhakarato kapia vinyl estermai i Haina, i Īnia, i Ūropi, me te US. Kei ngā wāhi katoa ngā mea pai. Kāore te whenua e whakatau i te kounga. Ko te mana whakahaere tukanga e whakatau i te kounga. He pai ake te whakahaere o tētahi wheketere i Shandong i tētahi mahi koretake i Stuttgart. Kua kite ahau i ngā mea e rua.

Kāore rawa te kapia iti rawa te utu i te kapia iti rawa. I ako ahau i tēnā i te tau 1997. I utua e au mā te whakamahi i tētahi tāke pakaru, ā, he kaihoko riri nui. Kāore anō kia rerekē te akoranga i roto i ngā tau 28. Kaua e ako pērā i ahau.
