He aha te Polyphenylene Sulfide (PPS)?

Ko te Polyphenylene Sulfide (PPS) he pūhui kirihou haurua-kiriata, he āhua kōwhai mā. Ko tōna ira rewa he tata ki te 290°C, ā, ko tōna mātotoru he tata ki te 1.35 karamu/cm³. Ko tōna tuara ngota - he mea tito mai i ngā mowhiti benzene me ngā ngota whanariki - ka hoatu he hanganga pakari, he tino pumau hoki.

E mōhiotia ana te PPS mō tōna pakeketanga teitei, tōna pumau wera, tōna ātete matū, me tōna kaha miihini. Nā tōna mahi tino pai, e mōhiotia whānuitia ana te PPS hei tētahi o ngā kirihou hangarau matua e ono, me te polyethylene terephthalate (PET), te nairon (PA), te polycarbonate (PC), te polyoxymethylene (POM), me te polyphenylene ether (PPO).

Ngā Puka me ngā Whakamahinga o te PPS

Kei te wātea ngā hua Polyphenylene Sulfide (PPS) i roto i ngā āhua me ngā taumata rerekē, pērā i ngā kapia, ngā muka, ngā miro, ngā kiriata, me ngā paninga, ā, he tino maha ngā whakamahinga. Ko ngā wāhi matua o te whakamahinga o te PPS ko te umanga motuka, te hiko me te hikohiko, te umanga matū, te ope taua me te parepare, te rāngai kakahu, me te tiaki taiao.

Ngā Wero Noa i roto i te PPSengā kirihou hangarau ame te pehea te whakaoti i aua raruraru

Ahakoa ōna āhuatanga pai rawa atu, he maha tonu ngā wero tukatuka me te mahi a ngā kirihou hangarau PPS i roto i ngā tono mahi. Anei ētahi o ngā take e toru e tino kitea ana me ō rātou otinga e rite ana:

1. Ngā Pakaru o ngā PPS Kāore i Whakakīia

Wero: He pakarukaru te PPS kāore i whakakīia, ā, ka whakawhāiti i tōna whakamahinga i ngā tono e hiahia ana kia nui te ātete ki te pānga, te ngāwari rānei (hei tauira, ngā wāhanga e pāngia ana e te ru, e te wiri rānei).

Ngā Take:

He iti te toronga i te wā whati nā te mea he pakari tōna hanganga ngota.

Te kore o ngā tāpiringa hei whakapakari i te pakari.

Ngā otinga:

Whakamahia ngā momo PPS kua whakapakaritia me te muka karāhe (hei tauira, 40% kua whakakīia ki te karāhe) me ngā whakakī kohuke rānei hei whakapai ake i te kaha me te pakari o te pānga.

Whakaranua ki ngā elastomers, ki ngā whakarerekētanga pānga rānei mō ngā tono motuhake.

2. Te Piri Kino mō ngā Paninga, te Hononga rānei

Wero: Nā te koretake o te matū o te PPS ka uaua te piri o ngā piripiri, ngā paninga, ngā peita rānei, ka uaua ai te huihuinga, te whakaotinga mata rānei (hei tauira, i roto i ngā whare hiko, i ngā wāhanga ahumahi kua pania rānei).

Ngā Take:

He iti te pūngao mata nā te hanganga matū kore-porowhita o te PPS.

Ātete ki te here matū, ki te mākū rānei o te mata.

Ngā otinga:

Whakamahia ngā maimoatanga mata pēnei i te whakairo plasma, te tukunga korona, te paninga matū rānei hei whakanui ake i te kaha o te mata.

Whakamahia ngā piripiri motuhake (hei tauira, he mea hanga ki te epoxy, ki te polyurethane rānei) i hangaia mō te PPS.

3. Te Whakamau me te Waku i roto i ngā Taupānga Hihiri

Wero: Ko ngā momo PPS kāore i whakakīia, ko ngā momo paerewa rānei, he nui te tere o te pakaru, te waku rānei i roto i ngā wāhanga neke pēnei i ngā peera, ngā taputapu, ngā hiri rānei, ka hua ake te rahunga wawe i roto i ngā tono hihiri.

Cngā ause:

He teitei te tauwehenga o te waku i roto i ngā PPS kāore i whakakīia.

He iti te whakahinuhinu i raro i ngā kawenga nui, i te nekehanga tonu rānei.

Ngā otinga:

Tīpakohiangā kōeke PPS kua whakahinuhinuhia me ngā tāpiringapērā i te PTFE, te graphite, te molybdenum disulfide rānei hei whakaiti i te waku me te whakapakari i te ātete ki te kakahu.

Whakamahia ngā papa whakapakari (hei tauira, kua whakakīia ki te muka waro) kia nui ake ai te kaha ki te pikau kawenga.

Ngā Āwhina Tukatuka Hinu SILIKE me ngā Kaiwhakarerekē Mata mō ngā Kirihou Hangarau PPS

Ngā Otinga Hou mō te Whakapai ake i te Ātete Pakaka o ngā Wāhanga Paheke PPS

Te whakauru i ngā tāpiringa silicone a SILIKE LYSI-530A me SILIMER 0110

He āwhina tukatuka hinu hou a LYSI-530A me SILIMER 0110, ā, he whakarerekētanga mata anō hoki mō te polyphenylene sulfide (PPS), i whakarewahia tata nei e SILIKE. He rite tonu te mahi a ēnei tāpiri silicone ki te polytetrafluoroethylene (PTFE), he iti nei te kaha o te mata. Nō reira, ka tino whakaitihia e rātou te tere kakahu me te tauwehenga waku o ngā hiato PPS.

He tino iti te tauwehenga waku o ēnei tāpiringa, ā, he hinu whakahinuhinu ā-roto tā rātou mahi. Ka hangaia he kiriata angiangi ki runga i te mata o te PPS ina pāngia e ngā kaha kutikuti, ā, ka whakaitihia te waku i waenga i te PPS me ngā mata e hono ana, ahakoa he mea whakarewa, he mea kirihou rānei.

Mā te whakamahi noa i te 3% LYSI-530A, ka taea te whakaiti i te tauwehenga waku hihiri ki te 0.158, ka hua ake he mata maeneene.

Hei tāpiritanga, mā te tāpiri i te 3% SILIMER 0110 ka taea te whiwhi i te tauwehenga waku iti o te 0.191, me te whakarato i te ātete ki te pakū rite ki te mea e tukuna ana e te 10% PTFE. E whakaatu ana tēnei i te whai huatanga me te kaha o ēnei tāpiringa ki te whakapai ake i te mahi me te pakari puta noa i ngā tono maha, he mea pai mō ngā wāhanga PPS reti, hurihuri, utaina hihiri rānei.

He tino pai te mahi a SILIKEngā hinu whakahinuhinu me ngā āwhina tukatuka e hangai ana ki te siliconemō te whānuitanga o ngā tono kirihou. Kua hangaia ā mātou tāpiri hei whakapai ake i te pai o te tukatuka me te whakarei ake i ngā āhuatanga o te mata o ngā kirihou me ngā matū kua whakarerekētia.

Kei te rapu koe i te tāpiri tika mō tō hanganga? Kōwhiria a SILIKE — tērā pea ka miharo koe ki te mahi a ā mātou otinga silicone.
Whakapai ake i te mahi PPS me ngā tāpiringa silicone e whakaiti ana i te waku me te kakahu — kāore e hiahiatia he PTFE.
