Ukukhetha ukuchitha kwe-powder yokuthintana ngokupheleleyo kwezindawo zokusebenza eziphakeme kakhulu

Ukuziqonda Izingxenye Zokuphakema Kwezikhathi: Kungani Ukuchitha Kwe-Powder Yokuthintana Ngokupheleleyo Akakwazi Ukubona Ukuphakema Kwezikhathi

I-200°C Yokuphakema Kwezikhathi: Izindlela Zokugcina Kwesikhathi Kwezinhlangano Zepoxy Nezinhlangano Zepolyester Ezizenzakale

Amakhamphu asebenzayo okukhanya kwezinkampani ezihlukene, ngokuvamile amaphutha nezinkampani zepoxy, ayadlula ukubhekana nempilo xa izintemperetsha ziphuma emva kwezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zezinkampani zez......

Ukubambisana Kwemithambo Yekhemikhali Nezinkinga Zokubhala Kwezinye Izingxenye: Indlela Okuyimithambo Yezinkulungwane Iyathola Ukuthi Ukuqonda Kwakho Kukhulu Kuphi

Umbala wokusebenza wokufaka kwezinkulungwane akuyiyo kuphela ukuthi yizinto zokubhala okuzimele. Kodwa, ubukhulu bakho buyikwazi kakhulu ngokuthi umbala wokubambisana kwezinkulungwane kuyibhala njani, ukuthi kuyibhala ngokufanafanani kwezinye izinye izinkulungwane, nokuthi izinkulungwane zokubambisana ziyiziphi. Izifomula zezinkulungwane zokuzimele ziyabhekana ngezinkulungwane eziningi zezinkulungwane ezingahlanganisiwe ngokuphelele kwezinye izinye izinkulungwane. Lokhu okungafanani kokubhala kuyenza amaphuzu okubhala okungafanani kwezinye izinkulungwane. Uma lezi zinkulungwane ziyabhalwa phansi kwembala yokuqonda (Tg), lezi zinkinga zokubhala ziyadlala indlela yezimbili zokuhlwa:

• Ukubhala kwezinkulungwane ngokuhamba kwezinkulungwane : Ukubhala okuhamba kwezinkulungwane nezinkulungwane zokubhala kwezinkulungwane kuyenza ukubhala kwezinkulungwane kwezinkulungwane
• Ukubhala kwezinkulungwane ngokuhamba kwezinkulungwane : Ukubhala kwezinkulungwane kuyenza ukuthi izinkulungwane ziyabhalwa ngokuphelele, ukubhala kwezinkulungwane zezinkulungwane nezinkulungwane zezinkulungwane

Izinsizimili ezimangalisayo zizokhuluma ngalesi simo ngokusebenzisa izilinganiso zezinkampani zokuhlanganisa eziphelele, ukugcina kwezinsizimili ngemuva kokugcina, nokudonsa amasimbi okususa umoya—okunikeza ukuthi izinsizimili ziyasebenza kahle ku-150–400°C ngaphezu kwemithombo yezinsizimili ezingaphansi.

Ukukhetha i-Resin System bakuze kubhekwe izinkinga zokusebenza kwezinsizimili zokugcina ezihlukene ngezintemperatura ezide.

I-Silicone-Polyester Hybrids: Ukusebenza okulinganiswe kuzokwenzela ukusebenza kahle kwezintemperatura ezi-350–450°C ngokuthekelwa kwezinsuku zonke.

Kodwa izinto zizingafune ukusebenza kumazinyo okukhulu kwe-350 ku-450 degrees Celsius ngokuphambili, amakholi we-silicone-polyester ayisisekelo esihle. Lezi zikhulukana zokufana ziyahlukanisa ukuthintana okuhle kwe-oxidation kwe-silicone nesifunda sokubaluleka kwe-polyester. Ngakho, bakhuluma kahle kakhulu kubizo bezinhlobo zezinkinga ezibalulekile zokugcina umbala, ukuchaza kwesikhwama, nokuphela kokubamba kusikhwama xa kubhekwa kumazinyo okukhulu ngemva yezinsuku eziningi. Noma ke isibonelo sesi-400 degrees Celsius, amakholi we-polyester amaningi aya kuhlukana kabusha emva kwezinsuku eziyishumi ezizibili, kodwa lezi zikhulukana ziyabamba isiqondiso sezinkampani zabo ngokwesibini ngokuphakeme kwe-85%. Abadlayi bayavakelwe ngokuthula kwe-glass transition temperature okuyinto eyenza lezi zikhulukana zibaleke kahle nakuba kubhekwa kumazinyo okukhulu futhi kubhekwa kumazinyo okuncane ngokuphambili. Lokhu kuyenza kubo kubalulekile kakhulu kubizo bezinyo ezibonakaliswa ngokuphambili kwezinyo ezikhulu kakhulu njengezinyo zokuphuma kwezinyo, izinyo zomkhumbi, nezinyo zemetal ezibophelela i-catalytic converters.

Izinhlangano Ze-Epoxy-Nesikhundla Sesihlangothi: Izisombululo Zokusebenza Kwezinkulu Kuya Kusukela Ku-600°C

Ukugcina vs. Isilinganisi Sesikhathi Sokusebenza: Ukuchazisa Ukubheka Okungafanele Okuphambili Ekukhombeni Kwemithombo Yokuqala Yekhobhela

Abaningi ababili bafana ngokubhakha isikhathi sokuhlanzwa nokuhlanzwa kwezinkampani zokufaka amaphetha. Sizobonisa: isikhathi sokuhlanzwa kusukela ku-150 ku-200 degrees Celsius kubasekelwe eminye imithombo. Lokhu kuyizindlela zokuhlaza okufanele kuzime kahle ukuthi izinkampani zokufaka amaphetha zihlanganise kahle ngokuphelele kumsebenzi wokufaka amaphetha. Manje isikhathi sokusebenza sibonisa isiphumo esisodwa.

Izinqubo Zemithi Yomkhumbi Nezinkampani Zokuphatha Isikhati: Kufuneka Kube Nenkululeko Yokubaluleka Kwesikhathi Eside Kusukela Kwe-500°C

Kodwa izinkampani zihamba ngokuzimisa kusukela kwezinkathi ezingaphezulu kwe-500°C, iziresini zezindaba zokusebenza kahle azikwazi ukuphatha isikhati kahle. Isiphumo sibonakala njengamathilili amashumi ayisikhombisa okuqondile nezinkampani zoceramiki. Lezi ziqondisa loo zinto ozizwa ngazo ngokuthi ziyizinhlobo zezinhlobo zezindaba ezinjalo: ukuguqula kwesikhathi eside, ukuvulwa kwe-oxygen, nokuphuma kwamaphuzu angafanele. Lokho okwenza lezi zinhlobo ziseworka kahle kuyilo lokusebenzisa izinhlobo zokugxilwa zezindaba ezinjalo emhlabeni, kungakhathali ukusebenzisa kuphela izinhlobo zokugxilwa zezindaba zokugxilwa kwe-covalent eziphathelene nezinhlobo zezindaba zokusebenza kahle. Lokhu okuhambisana kuyilo lokuba kubhekise izinhlobo zokugxilwa zabo nangona izinhlobo zezindaba zokusebenza kahle zizokwakha kahle kusukela kwezinkathi eziningi. Kusukela kwezinhlobo zezindaba zokusebenza kahle zokusebenza kwezindaba zokusebenza kahle, lokhu kuyilo lokuthuthukiswa kakhulu kwezindaba zezindaba zokusebenza kahle.
