Mowhiti-O kua pania ki te PTFE
He aha ngā Mowhiti-O kua Pania ki te PTFE?
Ko ngā mowhiti-O kua pania ki te PTFE he hiri hiato kei roto he matua mowhiti-O rapa tuku iho (hei tauira, NBR, FKM, EPDM, VMQ) hei papa rapa, ka pania ki runga he kiriata polytetrafluoroethylene (PTFE) angiangi, ōrite, ā, he piri pūmau. Ka whakakotahihia e tēnei hanganga ngā painga o ngā rauemi e rua, ka hua ake he āhuatanga mahi ahurei.
Ngā Wāhi Whakamahinga Matua
Nā ō rātou āhuatanga tino pai, e whakamahia whānuitia ana ngā mowhiti-O kua pania ki te PTFE i roto i ngā taiao uaua me ngā whakaritenga hiri motuhake:
Te Ahumahi Matū me te Pētara:
Te hiri i ngā takirere, ngā papu, ngā tauhohenga, me ngā pātara paipa e whakahaere ana i ngā pāpāho tino waikura pēnei i ngā waikawa kaha, ngā kawakore kaha, ngā kaiwhakahāora kaha, me ngā whakarewa waro.
Te hiri i roto i ngā pūnaha tuku matū parakore-teitei hei ārai i te poke.
Te Ahumahi Rongoā me te Hangarau Koiora:
Te hiri mō ngā taputapu tukatuka e hiahia ana kia tino ma, kia kaua e ringihia, kia kaua hoki e poke (hei tauira, ngā pūwero koiora, ngā mīhini whakapūkara, ngā pūnaha purenga, ngā raina whakakī).
He ātete te hiri ki ngā matū horoi kaha me te mamaoa pāmahana teitei e whakamahia ana i roto i ngā tukanga CIP (Horoi-i-te-Wāhi) me te SIP (Whakahoromata-i-te-Wāhi).
Ahumahi Kai me te Inu:
Ngā hiri mō ngā taputapu e tutuki ana i ngā ture pā kai a te FDA/USDA/EU (hei tauira, ngā taputapu tukatuka, ngā whakakī, ngā paipa).
Ātete ki ngā kai horoi me ngā wai whakamate kai-kai.
Ahumahi Ārahi me te Hikohiko:
He hiri mō ngā pūnaha tuku me te whakahaere o te wai tino parakore (UPW) me ngā pūnaha tuku matū tino parakore (waikawa, kawakore, whakarewa), e hiahia ana kia tino iti te whakaputa matūriki me te tango i ngā katote konganuku.
Ngā hiri mō ngā rūma korehau me ngā taputapu tukatuka parāuma (he iti noa te hau e hiahiatia ana).
Ahumahi Motuka:
Te hiri i ngā wāhi pāmahana teitei pēnei i ngā pūnaha turbocharger me ngā pūnaha EGR.
Ngā hiri e hiahia ana ki te iti o te waku me te ātete matū i roto i ngā tuku me ngā pūnaha wahie.
Ngā tono i roto i ngā pūnaha whakamatao pākahiko o ngā waka pūngao hou.
Te Rererangi me te Tiaki:
Ngā hiri e hiahia ana kia tino pono, kia ātete ki ngā pāmahana tino kino, kia ātete hoki ki ngā wahie motuhake/ngā waipēhi i roto i ngā pūnaha waipēhi, ngā pūnaha wahie, me ngā pūnaha whakahaere taiao.
Ahumahi Whānui:
He hiri mō ngā rango hau me te waipēhi e hiahia ana ki te iti o te waku, te roa o te ora, me te ātete ki te kakahu (ina koa mō te nekehanga tauutuutu tere-teitei, auau-teitei).
He hiri mō ngā momo takirere, papu, me ngā hononga e hiahia ana ki te ātete matū me ngā āhuatanga kore-piri.
Ngā hiri mō ngā taputapu korehau (he iti noa te hau e hiahiatia ana).
Ngā Painga Ahurei me ngā Āhuatanga Mahi
Ko te painga matua o ngā mowhiti-O kua pania ki te PTFE kei roto i te mahi hiato whakarei ake i ahu mai i tōna hanganga:
Te Āhua Matū Tino Pai:
Ko tētahi o ngā painga matua. He tino ātete te PTFE ki ngā matū katoa (tae atu ki ngā waikawa kaha, ngā kawakore kaha, ngā wai regia, ngā whakarewa waro, me ētahi atu), e kore e taea e te nuinga o ngā papa rapa te whakatutuki takitahi. Ka wehea pai e te paninga te pāpāho waikura mai i te matua rapa o roto, ka whakawhānui ake i te whānuitanga o te tono o te mowhiti-O i roto i ngā taiao matū tino kino.
Te Tauwehenga Waku Tino Iti (CoF):
He painga nui. Ko te PTFE tētahi o ngā uara CoF iti rawa i roto i ngā rauemi totoka e mōhiotia ana (ko te tikanga he 0.05-0.1). Nā tēnei ka tino pai ngā mowhiti-O pania ki ngā tono hiri hihiri (hei tauira, ngā tokotoko piston tauutuutu, ngā pou hurihuri):
Ka tino whakaiti i te waku pakaru me te waku oma.
Ka whakaiti i te wera me te kakahu e puta mai ana i te waku.
Ka whakaroa i te roa o te hiri (ina koa i ngā whakamahinga tere-nui, auau-nui).
Ka whakapai ake i te whai huatanga o te pūngao o te pūnaha.
Awhe Pāmahana Whakahaere Whānui:
Ka mau tonu te mahi a te paninga PTFE puta noa i te whānuitanga o te pāmahana mai i te -200°C ki te +260°C (mō te wā poto tae atu ki te +300°C). Ka whakaroahia e tēnei te rohe pāmahana o runga o te mowhiti-O rapa turanga (hei tauira, ko te turanga NBR ka herea ki te ~120°C, engari me te paninga PTFE ka taea te whakamahi i ngā pāmahana teitei ake, i runga i te rapa i whiriwhiria). Ka whakapūmautia hoki te mahi pāmahana iti.
Ngā Āhuatanga Pai rawa atu mō te Kore-Pīpiri, me te Kore-Makuku:
He iti rawa te kaha o te mata o te PTFE, ā, he tino ātete ki te piri, kāore hoki e mākū i te wai me ngā wai hinu. Ko te hua o tēnei:
Ka whakaitihia te poke, te kōkō, te piri rānei o ngā toenga pāpāho ki ngā mata hiri.
He ngāwari te horoi, he mea tino pai mō ngā rāngai akuaku nui pēnei i te kai me te rongoā.
I mau tonu te mahi hiri ahakoa ngā rauemi matotoru.
Te Maama Nui, te Iti o ngā Reachables:
Mā te mata paninga PTFE maeneene, matotoru ka whakaitihia te rerenga o ngā matūriki, ngā tāpiringa, ngā matū taumaha-iti rānei. He mea nui tēnei mō ngā tono tino parakore i roto i ngā haurua-ā-ira, ngā rongoā, ngā hangarau koiora, me te kai me te inu, ā, ka ārai pai i te poke o ngā hua.
Ātete Pai ki te Mau:
Ahakoa kāore i te tino pai te ātete kakahu o te PTFE, he tino iti te CoF ka whakaiti i ngā reiti kakahu. Ina honoa ki tētahi papa rapa e tika ana (e whakarato ana i te tautoko me te manawanui) me te whakaoti/whakahinuhinu mata e tika ana, he pai ake te ātete kakahu o ngā mowhiti-O pania i ngā mowhiti-O rapa tahanga i roto i ngā tono hihiri.
Te Ātete Matū Whakarei ake o te Papa Rapa:
Mā te paninga ka tiakina te pūtake rapa o roto mai i te whakaekenga a te pāpāho, ka taea te whakamahi i ngā rauemi rapa he pai ake ngā āhuatanga ā-roto (pēnei i te ngāwari, te utu rānei, hei tauira, te NBR) ki roto i ngā pāpāho ka pupuhi, ka whakapakeke, ka whakaiti rānei i te rapa. Ka "whakapakari" i te ngāwari o te rapa ki te ātete matū o te PTFE.
Hototahi Pai ki te Korehau:
He pai te mātotoru o ngā paninga PTFE kounga teitei, ā, he iti te hau e puta mai ana i waho, me te ngāwari hoki o te matua rapa, e whakarato ana i te hiri korehau whai hua.
3. Ngā Whakaaro Hira
Utu: He nui ake i ngā mowhiti-O rapa paerewa.
Ngā Whakaritenga Tāutanga: Me āta whakahaere kia kore ai e pakaru te paninga i ngā taputapu koi. Me whai kiko whakakī tika ngā awaawa tāutanga, me ngā mata maeneene hoki.
Te Pūmautanga o te Paninga: He mea nui te kounga o te paninga (te piri, te ōritetanga, te korenga o ngā kōhao iti). Mēnā ka pakaru te paninga, ka ngaro te ātete matū o te rapa e kitea ana.
Huinga Pēhanga: Ka whakawhirinaki te nuinga ki te papa rapa kua tīpakohia. Kāore te paninga tonu e whakarato i te ātete pēhanga.
Te Ora Mahi Hihiri: Ahakoa he pai ake i te rapa tahanga, ka memeha haere te paninga i raro i te nekehanga hurihuri, hurihuri rānei mō te wā roa. Mā te whiriwhiri i ngā rapa turanga ātete ki te kakahu (hei tauira, FKM) me te hoahoa kua arotauhia ka roa ake te ora.
Whakarāpopototanga
Ko te uara matua o ngā mowhiti-O kua pania ki te PTFE kei roto i te āhua o te paninga PTFE e whakarato ana i te koretake matū pai rawa atu, he tauwehenga waku tino iti, he whānuitanga pāmahana whānui, he āhuatanga kore-piri, he ma teitei, me te tiaki papa i ngā mowhiti-O rapa tuku iho. He otinga tino pai ēnei mō ngā wero hiri uaua e pā ana ki te waikura kaha, te ma teitei, te waku iti, me ngā whānuitanga pāmahana whānui. I te wā e whiriwhiri ana, he mea nui kia whiriwhiria te rauemi papa rapa me ngā whakaritenga paninga e tika ana i runga i te tono motuhake (pāpāho, pāmahana, pēhanga, hihiri/pūmau), me te whakarite kia tika te tāutanga me te tiaki hei pupuri i te kounga o te paninga me te mahi hiri.
