He aha te takirere kuaha maripi polyurethane?
Takirere kēti maripi polyurethanee pā ana ki tētahi takirere kēti maripi me te hiri nohoanga takirere polyurethane.Polyurethane (PU)He āhuatanga o te ātete hinu, te ātete kakahu, te ātete pāmahana iti, te ātete koroheketanga, te pakeketanga teitei, te ngāwari pai me te mahi paitini pai. He maha ngā wā e whakamahia ana mō ngā matūriki pakeke-teitei me ngā paipa reo kei roto te hau me te wai. He pai te mahi hiri me te ātete kakahu kaha-teitei.
E mōhiotia ana te polyurethane ko te "rapa ātete-mau". Kāore tōna ātete hinu i raro iho i te rapa nitrile, ā, he rite ki te rapa polysulfide. He tino pai mō ngā paipa reo maha e hiahia ana kia hiritia nuitia, kia kaha hoki te pakaru o ngā matūriki.

Ngā Āhuatanga Hoahoa:
Takirere Kēti Maripi PolyurethaneKoia tēnei tetahi o ngā rauemi tino ātete ki te kirikiri. Ko tā mātou Polyurethane Knife Gate Valve (NSW) he mea whakakikorua katoa ki te urethane kounga teitei, he mea e hira ake ana i te roa o te mau o te rapa kāpia me ētahi atu raina ngohengohe, ngā rauemi ringaringa rānei.
1.Kore turuturuKo te tinana takirere urethane kua whakakikoruatia katoatia me te hiri kuaha elastomer kua whakarewahia hei ārai i te turuturu tuturu o te hiri takirere me te tinana takirere tonu i te wā e mahi ana.
2.Te roa o te ora mauKo ngā arai urethane kounga teitei ātete ki te kirikiri, me ngā kēti maripi kowiri tira pakari me te hoahoa ahurei o te takirere tonu e whakarato ana i te roa o te ora mahi.
3.Whakaweto ā-ruaIna puta te rere whakamuri, ka taea hoki te whakamahi i a NSW hei ārai.
4.Hoahoa horoi-ā-rotoI te wā e kati ana te takirere, ka hurihia e te kuaha maripi piko te paru e rere ana ki te nohoanga o te arai urethane piko, ka puta he aueuetanga, ka whakanuia te rere, kātahi ka tukuna te paru i waho o te raro o te urethane i te wā e tau ana te kuaha ki roto i te nohoanga.
5. Ngā hanga hou wateaIna hiahiatia he hanga anō, ka taea te whakakapi i ngā wāhanga pakaru (ngā urethane, ngā hiri kēti, ngā kēti maripi) i te mara. Ka taea te whakamahi anō i ngā tinana takirere me ētahi atu wāhanga.
Ngā Kōwhiringa
1. Mowhiti Nohoanga (Ngā Raina):He maha ngā momo urethane e wātea ana.
2. Ngā Kūaha Takirere:Ko ngā kēti SS304 kua pania ki te chromium mārō te paerewa. Kei te wātea ētahi atu koranu (SS316, 410, 416, 17-4PH…). Kei te wātea hoki ngā paninga kēti kōwhiringa.
3. Kei te wātea ngā PN10, PN16, PN25, me te 150LB.
4. Kei te wātea ngā kaiwhakaoho kōwhiringa.
