Mekhoa ea ho ntlafatsa ho tiea ha mekoallo ea nylon

Molamu oa rona oa nylon o sebelisoang ka tloaelo PA6 e leng thepa ea crystalline thermoplastic, thepa ea nylon e bonolo ho monya metsi, e nang le lihlopha tsa hydrophilic (acylamino). 

Tabeng ea li-polymers tsa crystalline, ho pholisa ka potlako haholo nakong ea ts'ebetso ea extrusion ho thibela thepa hore e se ke ea khanya ka tlhaho le ho beha, e leng se hlahisang khatello e matla ea ka hare ka hare ho thepa.Tabeng ea lithupa tsa nylon tse e-s'o "halefa", li-macromolecules li ntse li atisa ho tsamaea ka mokhoa oa tlhaho, oa kristale ka mor'a ho beha, e leng se lebisang keketsehong e eketsehileng ea khatello ea maikutlo ka hare ho thepa.Ka hona, brittleness ea likarolo tsa nylon ntle le ts'ebetso ea ho belisa e phahame haholo, 'me ho bonolo ho oa kapa ho robeha ha e kenngoa tlas'a matla a ka ntle. 

Joale, ho thoe'ng haeba re lumella limolek'hule tsa nylon tse seng li entsoe hore li tsitse le ho phatsima ho felisa khatello ea kelello ka hohle kamoo ho ka khonehang?Ke seo re se bitsang ho belisa, 'me mokhoa oa ho belisa o hlile o tšoana le ts'ebetso ea rona ea "tempering" ea tšepe.Ke ho lumella likarolo tsa nylon hore li kene ka mocheso o itseng oa metsi, e le hore li-macromolecules tsa eona tse ka hare li sekamele ho ea ka tlhaho 'me li finyelle ho leka-lekana ha crystallization ea ka hare le decrystallization, e le ho felisa khatello ea kelello ea ka hare.Ts'ebetso e ka ntle ke: ho tiea ha likarolo tsa nylon ho matlafatsoa haholo, 'me bofokoli bo fela. 

  Joale ke hobane'ng ha u e pheha ka metsi?Ke hobane nylon e na le sehlopha sa hydrophilic - acylamino sehlopha, se etsang hore nylon e monye metsi habonolo, empa ka mor'a hore nylon e monye metsi a itseng, e thusa mokhoa oa eona oa ka hare oa macromolecule le motsamao oa crystallization.

  Mocheso o betere le nako ea ho belisa lihlahla tsa nylon le likarolo tsa nylon: 90-100, lihora tse 2-8.Ka tlase ho likhato tse 90, phello ha e ntle, 'me lihora tse fetang 8, ho ke ke ha e-ba le liphello tse molemo.Mabapi le ts'ebetso ea litšenyehelo, maemo a ka holimo a ts'ebetso a molemo.Huafu Nylon e hlahisa lihlahla tsa nayilone tse ntšo tsa MC tse thata tse nang le 5-15% molybdenum disulfide, 3% e toughening agent, MC casting type "Huafu" nylon e le thepa ea motheo, e eketsa mefuta eohle ea liphetoho ts'ebetsong, e etsa hore e se ke ea senyeha. , e hana ho bola, ha e tsofale, e itlotsa, e monyang lerata.E na le khanyetso e phahameng ea ho roala, ho hanyetsa tšusumetso, ha ho bonolo ho tšoara shaft, fusion, hore e se ke ea utloisa koranta bohloko, potoloho e telele ea lubrication, e eketsa likhaba tsa khalase, graphite le lisebelisoa tse ling tsa lik'hemik'hale ho etsa hore thepa ea eona ea 'mele e se ke ea sebetsa, e telele haholo. bophelo, boholo ba thepa ea mechine semela ho etsa tšehetsa tšebeliso ea liphello tse molemo.Re amohela ka tieo batho ba tsoang libakeng tsohle ho etela k'hamphani ea rona le ho botsa lipotso!
