He aha te ngongo ptfe | BESTEFLON

I ngā tau tata nei, ko te polytetrafluoroethylene (Teflon) he momo hua ārai-paru me te ārai-paru mō te hiko me te ahumahi hinu. Heoi, me aro nui ki ngā raruraru e whai ake nei inaKua whakakikoruatia ki te PTFEngongo waiKa whakarewaina te paipa, ki te kore ka pāngia te roa o te mahi me te haumaru o te paipa kua whakapurua ki te PTFE.

1. Kāore e whakaaetia kia pakaru te konganuku turanga i te wā e horoia ana te taputapu huihuinga. Kāore e whakaaetia kia pā te pewa ki te konganuku turanga i te wā e whakarewahia ana.

2. I te wāhanga whakarara o te whakarewa whakarara, me nui ake te teitei o te whakarewa whakarara i te 5mm, me nui ake, me ōrite rānei te koki whakakikorua ki te 3mm, ā, me nui ake, me ōrite rānei te koki o roto ki te 10mm.

3. I te wā e whakarewahia ana te anga o te paipa PTFE, he pai ake te whakamahi i te tikanga whakarewa o te whakarewa taha-rua. E hiahiatia ana tēnei e te taumata hangarau o ā mātou kaimahi, me papatahi te whakarewa (he maeneene, he maeneene rānei te whakawhiti), kāore he pūwero, he hononga whakarewa me te whakaurunga paru, ā, kaua te teitei o te whakarewa e neke atu i te 2mm. I muri i te whakarewa, me tango katoa te tauhiuhi i puta mai i te whakarewa.

4. Me whakamahi te whakarewa tonu i roto i te whakarewa o te paipa PTFE, ā, kaua te hononga whakarewa e pakaru, e tapahia tonutia rānei. Ngā Rapunga e Pā Ana:ngongo PTFE whiri, Ngongo PTFE miro

Ko te Polytetrafluoroethylene (PTFE) tētahi o ngā ingoa e whakamahia whānuitia ana mō te polytetrafluoroethylene. Ka whakamahia te ngongo PTFE i roto i ngā ngongo kowiri tira, nō reira he roa ake te ora o te ngongo i te ngongo rapa, i te ngongo rapa rānei kua takaihia ki te kowiri tira. He maha ngā painga o tēnei ngongo i ngā hua rapa.

Akomanga I: Paipa me ngā hononga paipa tika kua whakarārangihia ki te PTFE

E mōhiotia whānuitia ana ko te paipa raina wetewete. I roto i tēnei tukanga, ka whakamahia te PTFE hei huri i te pae. He pai mō ngā paipa kawe pēhanga noa me te pēhanga pai (pēnei i te paipa maimoatanga para e toru, me ētahi atu), ā, kaua e whakamahia mō te paipa he kawenga (pēnei i te tomokanga me te putanga o te papu me te paipa ka taea te whakaputa pēhanga kino mā te maturuturu, te whakamatao ohorere rānei).

Whakatakotoranga diameter: dn25-500mm

Te pāmahana ratonga: - 40-180oc

Pēhanga ratonga: 1.6Mpa

Akomanga II: Paipa tika me ngā hononga paipa PTFE kua whakarārangihia kiato

E mōhiotia whānuitia ana ko te paipa arai piripono e takai ana ki te waea rino.

Te tukanga hanga: tuatahi, ka takaihia ētahi paparanga o te kiriata PTFE ki runga i te pokepokea ai, kātahi ka takaihia te waea maitai (Ø 0.5-1mm) ki runga i te kiriata PTFE, kātahi ka takaihia ētahi paparanga o te kiriata PTFE angiangi ki waho o te waea maitai, ā, i te mutunga ka takaihia ki roto i te oumu hei hanga. He maeneene te pakitara o roto o te paipa PTFE i hangaia mā tēnei tukanga, ā, he porowhita te pakitara o waho nā te kaha o te rahi me te kaha o te waea maitai.

Ka whakakīia te wāhi i waenganui i te pakitara o waho o te paipa PTFE me te pakitara o roto o te paipa maitai ki te kapia (kāore he hau e toe ana). Ka taea te here pūmau i te kapia whakakī ki te paipa maitai. I taua wā anō, ka taea te takai pūmau ki te pakitara o waho o te arai PTFE porowhita. I muri i te whakamaroketanga o te kapia kua whakakīia, ka hangaia he ngaru porowhita e āraia ana e te ngaru pakitara o waho o te arai. He rite tēnei hanganga ki te whakakotahitanga o te nati me te pūtu. I tetahi taha, ka taea e ia te whakawhāiti me te whakatika i te whānui wera me te whakaheke makariri o te arai PTFE; i tetahi atu taha, ka taea e te pakari o te waea maitai te whakapai ake i te ātete pēhanga kino o te arai PTFE.

Whakatakotoranga diameter: dn25-200 mm

Te pāmahana mahi: - 50-180oc

Pēhanga mahi: 0.5-1.6mpa

Ko te momo tuatoru: Paipa pana (kōpeke) PTFE kua whakarārangihia ki te paipa tika

E mōhiotia whānuitia ana ko te paipa tika kua whakarārangihia ki te pana (pēhi), e whakamahia whānuitia ana i ngā whenua whakawhanake i ngā tau 1990.

Te tukanga hanga: tuatahi, ka whakamahia te paura PTFE kawemai hei pana (whakaputa) i te paipa, kātahi ka panaia ki roto i te paipa maitai kore hononga (he paku nui ake te diameter o waho o te arai i te diameter o roto o te paipa maitai mā te 1.5-2mm) hei hanga i tētahi arai piripono kore hononga. Hei whakakore i te pēhanga, ka maka ki roto i te oumu ka whakamahana ki te 180°C kia mau tonu te pāmahana, kia taea ai te whakamahi i te pāmahana i raro i te 180°C. I taua wā anō, pana (pēhia) te kakau o te paipa.

He pai ake te kaha o te kume i tērā o te ngongo pakaru. He tino pai te ātete o te paipa ki te pēhanga pai me te pēhanga kino.

Te rerekētanga i waenga i te arai PTFE me te arai rapa

Ko te whakapuru tetrafluoroethylene e whakamahia ana e te ātete waikura o te fluorine, te ātete pāmahana teitei, te ātete waikawa me te kawakore kaha, te piri pai, te roa o te ora mahi me te ātete uru kaha. Ko te rehu katoa o te tetrafluoroethylene he mahi hangarau teitei, he aha ngā rere o tana tukanga? 1. I mua i te rehu, me pania te mata ki te onepu me te whakakoi, ā, ka rehuhia he paparanga o te paninga motuhake. 2. Kātahi ka utaina te paura fluoroplastic ki ngā taputapu hiko-teitei-ngaohiko, ā, ka piri ōrite ki te mata o te mea mahi i raro i te mahi a te mara hiko. 3. I muri i te tunu i te pāmahana teitei, ka rewa ngā matūriki clinker hei paparanga tiaki matotoru, ka piri pūmau ki te mata o te mea mahi. Hei tauira, me rehu me tunu anō hoki he kiriata paninga 1 mm te matotoru mō te 5-6 wā. I te nuinga o te wā, ka taea te rehu i te matotoru mōrahi ki te 2mm. He hangarau whānui te whakapuru PTFE i tēnei wā. Ka whakamahia katoatia e ia te ātete waikura o te fluorine, te parakore teitei, te ma, te kore piri, te kore mākū, te whakahinuhinu-ake, te ātete kakahu, te ātete pāmahana teitei me te iti, te whakamarumaru, me ētahi atu i roto i te tukanga hanga, ka whakatikatika tonuhia tōna ngaohiko me tōna iahiko ki te āhua pai hei whakatutuki i te pānga paninga. Ka kiia hoki te arai rapa he arai rapa. Ko te tikanga he whakapiri i te pereti rapa tukatuka ki runga i te mata whakarewa me te piripiri hei wehe i te reo waikura mai i te anga whakarewa hei tiaki. Ka whakamahia te rapa taiao me te rapa hangai mō te arai. Ko te nuinga o te rapa e whakamahia ana i roto i te arai taputapu matū he rapa taiao. Ko te wāhanga matua o te rapa taiao ko te polymer cis o te isoprene, ka whakamomonahia mā te tāpiri whanariki. He ātete wera me te kaha miihini te rapa whakamomona. Ka taea te wehewehe ki ngā momo rapa ngohengohe, rapa āhua-mārō me te rapa mārō e toru. He pai te ātete waikura, te ātete koroheketanga me te kaha piri ki te whakarewa te rapa mārō. He pai te ātete makariri, te ātete wera me te ātete pānga o te rapa ngohengohe, ā, he ngāwari; kei waenganui i ngā momo e rua te rapa āhua-mārō. Haunga ngā waikura kaha me ētahi whakarewa, ka taea e te rapa mārō te ātete i te waikura o te nuinga o ngā waikawa kore-waro, ngā waikawa waro, ngā kawakore, ngā tote me ngā waipiro. Nō reira, ko te arai rapa mārō te mea matua hei ārai i te waikura kore-whakarewa. Ka taea te wehewehe i te rapa whakamomona ki te rapa whakamomona mua, te rapa whakamomona wai wera pēhanga noa, me te rapa whakamomona tūturu. Ka whakamahia te rapa whakamomona mua i roto i ngā taputapu whakamātao nui.
