Ko te Polyamide (PA66), e mōhiotia ana ko Nylon 66, ko te polyhexamethylene adipamide rānei, he kirihou hangarau he tino pai te mahi, i hangaia mā te polycondensation o te hexamethylenediamine me te waikawa adipic. Kei a ia ēnei āhuatanga matua:
Te Kaha me te Pūmau: He nui ake te kaha ā-mīhini, te tauwehenga ngāwari, me te pūmau o te PA66 i te PA6.
Ātete Paku Tino Pai: Hei tētahi o ngā polyamides ātete-paku pai rawa atu, he tino pai te PA66 i roto i ngā tono pēnei i ngā wāhanga miihini, ngā taputapu, ngā peera, me ētahi atu wāhanga ātete-paku.
Ātete Wera Pai rawa atu: He pai ake te ātete wera o PA66 i te PA66, nā te mea he 250-260°C tōna ira rewa, ā, he pai hoki mō ngā taiao pāmahana teitei.
Ātete Matū Kaha: He ātete a PA66 ki te waikura mai i ngā hinu, ngā waikawa, ngā kawakore, me ngā momo matū maha.
Ngā Āhuatanga Pai o te Whakahinuhinu-ā-Whaiaro: Haunga te ātete ki te kakahu, he āhuatanga whakahinuhinu-ā-whaiaro anō hoki tā PA66, ko te tuarua anake ki te POM (Polyoxymethylene).
He Ātete Pai ki te Pakarutanga me te Ātete Pānga: He tino pai te ātete a PA66 ki te pakarutanga me te kaha pānga.
Te Pūmautanga o ngā Ahu: He iti ake te mimiti o te makuku o te PA66 ki te PA6, ahakoa ka pā tonu te makuku ki tōna pumautanga o ngā ahu.
Whānuitanga o ngā Whakamahinga: E whakamahia whānuitia ana te PA66 i roto i ngā wāhanga miihini huri noa i ngā miihini motuka, ngā taputapu hiko me te hiko, ngā taputapu ahumahi, ngā kakahu, me te maha atu.
Ahakoa he maha ngā painga o te PA66, ka taea tonu te whakapai ake i tōna ātete ki te kakahu kia pai ai te whakamahi i roto i ngā taiao ahumahi uaua.
Ka tūhuratia e tēnei tuhinga ngā tikanga whakarerekētanga kua whakamātauhia mō te PA66, ā, ka whakaurua mai hoki te SILIKE LYSI-704, hetāpiri tukatuka hinu whakahinuhinu e hangai ana ki te siliconehe pai ake te ātete ki te kakahu, me te pumau ki te whakataurite ki ngā otinga PTFE tuku iho.
He aha ngā hangarau whakarerekētanga motuhake hei whakapai ake i te ātete ki te kakahu o PA66 mō te whakamahinga ahumahi?
Ngā Tikanga Tuku Iho hei Whakapai ake i te Ātete ki te Maukati PA66 mō te Whakamahinga Ahumahi:
1. Te Tāpiri i ngā Muka Whakakaha
Muka Karāhe: Ka tāpiri i te kaha kume, te pakari, me te ātete ki te pakū, ka mārō ake, ka roa ake hoki te PA66. Mā te tāpiri i te 15% ki te 50% o te muka karāhe ka nui ake te ātete ki te kakahu me te pumau.
Muka Waro: Ka whakapai ake i te ātete ki te pānga, te pakari, me te whakaiti i te taumaha. Ka whakarei ake hoki i te ātete ki te kakahu me te kaha ā-ringa mō ngā wāhanga hanganga me ngā wāhanga mahi teitei.
2. Te Whakamahinga o ngā Whakakī Kohuke
Ngā Whakakī Kohuke: Ka whakapakeke ēnei whakakī i te mata PA66, ka whakaiti i ngā tere pakaru i roto i ngā taiao tino koi. Ka whakapai ake hoki i te pumau o ngā āhuatanga mā te whakaiti i te whānui o te wera me te whakanui ake i te pāmahana piko wera, ka whai wāhi ki te roa o te ora mahi i roto i ngā āhuatanga uaua.
3. Te Whakaurunga o ngā Hinu Whakahinuhinu Totoka me ngā Tāpiringa
Ngā Tāpiri: Ngā tāpiri pēnei i te PTFE, MoS₂, rāneingā puranga matua siliconewhakaiti i te waku me te kakahu i runga i te mata PA66, ka maeneene ake te mahi me te roa ake o te ora o te wāhanga, inā koa i ngā wāhanga miihini e neke ana.
4. Ngā Whakarerekētanga Matū (Te Whakakotahitanga)
Ngā Whakarerekētanga Matū: Mā te whakauru i ngā waeine hanganga hou, i ngā copolymer rānei, ka whakaiti i te mimiti o te makuku, ka whakapakari i te pakari, ā, ka whakapai ake i te pakeketanga o te mata, ā, ka whakanui ake i te ātete ki te kakahu.
5. Ngā Kaiwhakarerekē Pānga me ngā Kaiwhakaōrite
Ngā Whakarerekētanga Pānga: Mā te tāpiri i ngā whakarerekētanga pānga (hei tauira, EPDM-G-MAH, POE-G-MAH) ka whakapai ake i te pakari me te roa i raro i te ahotea ā-mīhini, ka tautoko ā-tikanga i te ātete kakahu mā te aukati i te hanganga kapiti.
6. Ngā Tikanga Tukatuka me te Whakamaroke kua Arotauhia
Te Whakamaroke Tika me te Tukatuka Whakahaere: He waiora te PA66, nō reira he mea nui te whakamaroke tika (i te 80–100°C mō te 2-4 hāora) i mua i te tukatuka hei karo i ngā hapa e pā ana ki te makuku ka pā kino ki te ātete ki te kakahu. Hei tāpiri, mā te pupuri i ngā pāmahana whakahaere i te wā e tukatukahia ana (260–300°C) ka noho kaha, ka pumau hoki te rauemi.
7. Ngā Maimoatanga Mata
Ngā Paninga Mata me ngā Hinu Whakahinuhinu: Mā te paninga o ngā hinu whakahinuhinu o waho, ngā paninga mata rānei, pērā i ngā paninga uku, whakarewa rānei, ka taea te whakaiti i te waku me te pakaru. He tino whai hua tēnei mō ngā tono tere-nui, kawenga-nui rānei, ina hiahiatia he whakaiti waku tāpiri hei whakaroa i te roa o te mahi a te rauemi.
Otinga Auaha Kore-PTFE mō ngā Kirihou Hangarau Polyamide Ātete-Kakahu (PA66): SILIKE LYSI-704
Haunga ngā tikanga whakarerekētanga tuku iho,SILIKE LYSI-704—he tāpiringa ātete-mau i ahu mai i te silicone—he tohu tēnei i tētahi ahunga whakamua nui ki te whakapai ake i te pakari me te mahi a te PA66.
Tirohanga Whānui mō te Hangarau Kirihou Whakarerekētanga
He tāpiringa hangai ki te silicone te LYSI-704 e whakarei ake ana i te ātete kakahu o te PA66 mā te hanga i tētahi paparanga hinu pumau i roto i te hanganga polymer. He rerekē ki ngā otinga ātete kakahu tuku iho pērā i te PTFE, ka marara noa te LYSI-704 puta noa i te nairona me ngā tere tāpiri tino iti.
LYSI-704 Ngā otinga matua mō te Hangarau Kirihou:
Ātete Paku Pai Rawa: He rite te ātete pakū o te LYSI-704 ki ngā otinga PTFE engari he iti ake te utu taiao, nā te mea kāore he fluorine, e aro ana ki te āwangawanga e piki haere ana mō te PFAS (ngā matū ia- me te polyfluoroalkyl).
Te Kaha Pānga Whakapai Ake: Haunga te whakarei ake i te ātete kakahu, ka whakapai ake anō hoki a LYSI-704 i te kaha pānga, he mea uaua i mua ki te whakatutuki i te wā kotahi me te ātete kakahu teitei.
Whakapai Ahua: Ina whakauruhia ki roto i te PA66 me ngā muka karāhe, ka aro atu a LYSI-704 ki te take o te muka e mānu ana, ka whakapai ake i te kounga o te mata, ā, he mea tino pai mō ngā tono e hira ana te āhua.
Te Oranga Tonu: Ka tukuna e tēnei hangarau silicone he huarahi kē atu i te PTFE hei oranga tonutanga, ka whakaiti i te whakapaunga rauemi me ngā tapuwae waro, me te whakarato hoki i te mahi teitei.
Ngā Hua Whakamātautau
Ngā tikanga mō te whakamātautau ātete kakahu: te pēhanga i te taumaha 10-kirokaramu, te pēhanga 40 kirokaramu ki runga i te tauira, me te roa o te 3 hāora.
I roto i te rauemi PA66, ko te tauwehenga waku o te tauira kau he 0.143, ā, ko te ngaronga papatipu nā te kakahu he 1084mg. Ahakoa kua tino heke te tauwehenga waku me te kakahu papatipu o te tauira me te PTFE tāpiri, kāore tonu e taea te rite ki te LYSI – 704.
Ina tāpirihia te 5% LYSI – 704, ko te tauwehenga waku he 0.103, ā, ko te papatipu kākahu he 93mg.
He aha te take i whakamahia ai te silicone masterbatch LYSI-704 ki runga ake i te PTFE?
-
He ātete kakahu rite, he pai ake rānei
-
Kāore he āwangawanga mō te PFAS
-
He iti ake te tere tāpiri e hiahiatia ana
-
Ngā painga tāpiri mō te whakaotinga mata
