Te Taonga Tuku Iho me ngā Wero o te Nairon-66

I te 28 o Pēpuere, 1935, i puta he whakatutukitanga nui i roto i te pūtaiao rauemi i te wa i angitu ai te hanga a te kaipūtaiao Amerikana a Wallace Hume Carothers i te Nylon-66, he polyamide me ngā āhuatanga whakamiharo. Nā tōna ira rewa teitei o te 263°C, tōna ātete tino pai ki ngā whakarewa noa, me te āhua rite ki te hiraka, i whakatakoto tēnei polymer auaha i tētahi paerewa hou o te ao mō te roa me te kaha o te muka. Ehara i te mea he tohu nui noa iho mō te umanga kakahu; he putanga nui hoki i roto i te whanaketanga o te matū polymer.

Kia tere whakamua ki tēnei rā, kei te noho tonu te Nylon-66 hei rauemi nui i roto i ngā ahumahi mahi-teitei pērā i te kakahu, te motuka, te hikohiko, me te waea me te taura. Heoi, i te pikinga ake o ngā whakaritenga mahi, ka puta he arai hangarau tonu mō te tukatuka PA66 e raru ana ngā kaihanga i ia rā.

Ngā "Pūwāhi Mamae" Tukatuka o PA66
Ahakoa e whakanuia ana a PA66 mō tōna pakari, he maha ngā arai tukatuka e arai ana i tōna hanganga ngota ā-roto:

• Rere Rewa Kino me te Pēhanga Putanga Teitei: Ko te matotoru teitei o te rewa PA66 ka whakawhāiti i te rere o te wai, ka piki ake te whakapaunga pūngao, ka pakaru ngā taputapu, ka whakawhāiti hoki i te tere whakaputa.

• Te Moemoeā "Muka Karāhe e Mānu Ana": Hei whakatutuki i te kaha hanganga tino nui, ka whakapakarihia te PA66 ki te 30%–50% Muka Karāhe (GF). Nā te kore e ōrite te tere rere o te muka karāhe me te anga nairona, ka heke pinepine ngā muka ki te mata. Ko te hua o tēnei ko te "Muka Mānu Ana"—he ma, he taratara ngā rārangi e whakakino ana i te mata, e hanga ana i ngā pūwāhi kukū ahotea, e whakararu ana i te hanganga o te wāhanga.

• Ngā Hapa Mata me te Ngaronga o te Māramatanga Tirohanga: Ka taea e te ahotea tukatuka nui te arahi ki te "kiri mangō" (pakaru rewa) te hanga mate rānei, ka puta te taratara o te mata me te whakapohehe i te māramatanga tirohanga o ngā polyamide mārama. He tino raruraru tēnei mō ngā tono e tino hira ana te kounga tirohanga, pērā i ngā paninga waea me te taura kounga teitei.

Ehara i te mea ka pā noa ēnei āhuatanga tukatuka ki te kounga o te hua, engari ka hua ake hoki he tere ake o te para, he roa ake ngā huringa whakaputa, me te pikinga o ngā utu whakahaere—ā, ka pā kino ki tō hua.

Hei paionia i roto ite whakarerekētanga pūmua e hangai ana ki te silicone,Ka whakaratohia e SILIKE ngā momo tāpiri siloxane mahi-teitei katoa, ngā masterbatch silicone, ngā tāpiri polymer, me ngā hangarau whakarerekētanga whakapai mata e whakarei ake ana i te roa, te ngāwari o te tukatuka, me te pumau o ngā pūnaha Nylon-66, Polyamide 66 GF.

Ngā Tāpiri Silicone a SILIKE: Te Otinga Whai Hua mō te Tukatuka PA66
Kei a SILIKE tētahi kohinga o ngā otinga motuhake kua hangaia hei whakarerekē i te kaha tukatuka o ngā pūnaha polyamide:

1. SILIKE Silicone Masterbatch
He whānuitia te whakamahinga hei hinu tukatuka me te tāpiri tukunga whai hua, SILIKEPūmua Hiraka LYSI-307meSilixone Masterbatch LYSI-407he tino pai mō ngā pūnaha kapia hototahi ki te PA6. Ka whakapai ake i ngā āhuatanga tukatuka me te kounga o te mata mā te whakarato:

• He pai ake te rere o te kapia, ā, he māmā ake te whakakī/te tuku i te pokepokea ai.

• He iti ake te taipana o te extruder me te iti ake o te tauwehenga waku (COF).

• He ātete nui ake ki te pakaru me te pakū.

Painga Matua: Te whakaputanga pai ake o ngā rīpene pakaru wera polyamide, kia tere ake ai te putanga me te tukunga maeneene o te pokepokea ai.

2.SILIKE SILIMER 5150: Te Auahatanga o te Ware Silicone Kua Whakarerekētia

Ko te tāpiri kirihou SILIMER 5150 a SILIKE he mea hanga motuhake hei whakatau i ngā wero tukatuka PA66 tino uaua, inā koa mō ngā tono kua whakakahangia ki te muka karāhe me te mārama:

• Whakakore i ngā "Muka Mānu": Mā te whakapai ake i te hototahitanga me te taurite rere i waenga i te kapia me ngā muka karāhe, ka whakarite te kaihoko whakamarara hinu silicone SILIMER 5150 kia ōrite te takai o ngā muka, kia kore ai e heke ki te mata. Ka hua ake he mutunga maeneene, he ōrite ahakoa he nui ngā uta GF.

• Te Rerenga Whakarei Ake: Hei hinu whakahinuhinu kaha ā-roto, ā-waho hoki, ka whakaitihia e te Modified Silicone Wax te matotoru o te rewa me te pēhanga whakaputa. Ka whakanui ake tēnei i te whai huatanga, ā, ka tiaki i ō taputapu mai i te pakaru nui.

• Kounga Mata Pai Rawa: Ka whakaitihia e te tāpiri silicone SILIKE te taratara o te mata, ka ārai hoki i te hanga o ngā mate, i ngā hapa "kiri mangō" rānei, kia pai ai te kanapa o te mata, kia tutuki ai ngā paerewa ataahua pakari.

• Te Māramatanga o te Tirohanga: He rerekē ki ngā ware pi tuku iho,Ngā tāpiringa silicone SILIKE me te āwhina whakaputa SILIMER 5150kia mau tonu te mārama o PA66 ahakoa te taumahatanga nui—he mea tino pai mō ngā paninga waea me ngā taura mārama.

• Te Pakaritanga Pai Ake: Haunga te tukatuka, ka whakarei ake ngā Tāpiri Silicone a SILIKE i te ātete ki te pakū o te wāhanga whakamutunga, ka roa ake te ora o te hua, ka whakaiti hoki i ngā utu tiaki mō te wā roa.

Ngā Pātai Auau: Te Arotau i te Tukatuka Polyamide Whakakahangia e te PA66 me te muka karāhe
P1: Me pēhea taku whakakore i te "Muka Mānu" (ngā rārangi mā) i runga i te mata o te PA66 kua whakapakarihia ki te muka karāhe?
A: Ka puta te "Muka Mānu" ina kore e ōrite ngā tere rere o te muka nairona me ngā muka karāhe. Mā te whakamahi i te SILIKE SILIMER 5150, he tāpiri ware piro kua whakarerekētia, ka whakapai ake i te hototahitanga o te atanga me te taurite rere. Mā tēnei ka whakarite kia whai hua te kapia PA66 ki te kapi i ngā muka (30%–50% GF), ka hua ake he mata maeneene, he ōrite, me te kore he rārangi muka e kitea ana.

Q2: He aha te huarahi pai hei whakaiti i te pēhanga whakaputa me te whakapai ake i te rere rewa i roto i te hanga PA66?
A: Ko te matotoru rewa nui i roto i te PA66 ka arahi i te pēhanga nui o te extrusion me te pakaru o ngā taputapu. Ko te SILIKE Silicone Masterbatch LYSI-407 me te SILIMER 5150 he hinu whakahinuhinu ā-roto, ā-waho hoki e mahi nui ana. Ka tino whakaitihia e rāua te matotoru rewa me te taipana extruder, ka taea ai te whakaiti i ngā pāmahana tukatuka, te whakaiti i te whakapaunga pūngao, me te whakanui ake i te kaha whakaputa.

P3: Ka taea e ngā tāpiringa tukatuka te whakapai ake i te kounga o te mata PA66 me te kore e ngaro te māramatanga whatu?
Āe. Ahakoa ka puta te kapua, te "kohu" rānei i ngā ware pi tuku iho, he mea hanga motuhake te SILIKE SILIMER 5150 mō ngā polyamide mārama. Ka whakaitihia ngā hapa mata pēnei i te "kiri mangō" me te hanga mate, me te pupuri tonu i te māramatanga whatu me te māramatanga e hiahiatia ana mō ngā paninga waea me te taura kounga teitei me ngā wāhanga PA66 kounga-whatu.
