Thepa e Tšeletseng ea Nylon

01 Ho hanyetsana le Abrasive

Nylon e na le thepa e tšoanang le polyester. Phapang ke hore mocheso o hanyetsanang le mocheso oa nylon o mpe ho feta oa polyester, matla a khoheli a khethehileng a nylon a nyenyane 'me a monya mongobo.nylone kholo ho feta ea polyester. Nylon e bonolo ho daea. Matla a eona, khanyetso ea abrasive le ho hanyetsa mokhathala kaofela li molemo ho feta polyester. Nylon e tla holofala habonolo, empa e na le ts'ebetso e ntle ea ho hlaphoheloa le ho ba le botsitso bo phahameng.

Bolelele bo phahameng ba nylon bo etsa hore e be ntle ho hanyetsanang le ts'ebetso ea ts'ebetso. Ho hanyetsa ho apara ha nylon ke eona e ntle ka ho fetisisa har'a likhoele tsohle, e leng makhetlo a 10 a phahameng ho feta a k'hothone le makhetlo a 20 ho feta a boea.

02 Matla a Khoheli a Khethehileng

Har'a likhoele tse ka sehloohong tsa maiketsetso (polyester, nylon, fiber ea acrylic le Vinal), matla a khoheli a khethehileng a nylon ke a manyane, e leng 1.14. Ka lebaka la matla a eona a khoheli a khethehileng, nylon e loketse lisebelisoa tsa ho sebetsa libakeng tse phahameng le lithabeng tse phahameng. Hape ka lebaka la matla a eona a phahameng, nylon e ka sebelisoa ha ho etsoa thapo, letlooa la ho qetela, khoele e ntle ea sisal le "hollow cored fiber".

03 Thepa ea Mocheso

Ha nylon e sebetsanoa, tšusumetso ea mocheso ho thepa ea fiber e lokela ho nkoa. Ha mocheso oa moea o chesang o feta 100 ℃, tahlehelo ea matla ea nylon e hlakile. Ke hobane tlas'a karabelo ea mocheso, thefiberLimolek'hule li tla ba le ho senyeha ha lik'hemik'hale tsa oxidative. Ka kakaretso, mocheso o tlase, matla a nylon a matlafala. Hobane ha mocheso o le tlaase, limolek'hule li na le motsamao o fokolang oa mocheso 'me matla a intermolecular a matla.

Mocheso oa kamore, matla a nylon staple fiber a ka fihla ho 57.33 ~ 66.15cN / tex 'me matla a nylon high-tenacity fiber a ka fihla ho 83.8cN / tex, e matla ka makhetlo a 2 ~ 3 ho feta ea fiber ea k'hothone. . Ho phaella moo, ho eketseha ha mocheso ho tla lebisa ho fokotseha ha nylon. Ha e le haufi le ntlha ea ho qhibiliha, ho fokotseha ho matla 'me fiber e tla ba mosehla.

04 Thepa ea Motlakase

The conductivity ea nylon e tlaase haholo. Kahoo ho tla ba bonolo ho bokella motlakase o tsitsitseng nakong ea tlhahiso. Empa ha mocheso o lekanyelitsoeng oa tikoloho o eketseha, conductivity ea eketseha e le ts'ebetso ea exponential. Ka mohlala, ha mongobo o lekanyelitsoeng o fetoha ho tloha ho 0 ho ea ho 100%, conductivity ea Nylon 66 e tla eketseha 10.⁶linako. Kahoo kalafo ea phepelo e kolobileng joalo ka sefafatsi sa moholi ha ho etsoa nylon e tla fokotsa ho bokellana ha motlakase o sa fetoheng.

05 Ts'ebetso ea Mongobo oa Mongobo

Nylon ke fiber ea hydrophobic. Empa ka har'a macromolecules ea nylon, ho na le lihlopha tse ngata tse fokolang tsa hydrophilic, joalo ka -C = O-NH-. 'Me lipheletsong tse peli tsa limolek'hule, ho boetse ho na le -NH2 le -COOH lihlopha tsa hydrophilic. Ka hona, ts'ebetso ea ho monya mongobo ea nylon e phahame ho feta ea likhoele tse ling tsohle tsa maiketsetso, e lebelletseng bakeng sa Vinal.

06 Thepa ea Lik'hemik'hale

Ho tsitsa ha lik'hemik'hale tsa nylon ho molemo, haholo-holo ho hanyetsa alkali. Ka tharollo ea 10% ea NaOH, ka mor'a ho sebetsa lihora tse 10 ho 85 ℃, matla a fiber a fokotseha 5% feela.

Sehlopha se sebetsang haholoanyane ka har'a macromolecule ea nylon ke sehlopha sa amide, se tla hlahisoa ka hydrolyzed tlasa maemo a itseng.

Acid e ka etsa hydrolyze macromolecules ea nylon mme ea baka ho fokotseha ha tekanyo ea fiber polymerization. Li-macromolecules tsa nylon le tsona li ka hydrolyze ka metsing ka holimo ho 150 ℃. Asiti le mocheso li ka susumetsa hydrolysis ea fiber.

Oxidant e matla e tla senya nylon, joalo kableachingphofo, sodium hypochlorite le hydrogen peroxide, joalo-joalo, e tla etsa hore ho robeha ha fiber molecular chain le ho fokotsa matla a fiber. Hape masela a tla ba mosehla ka mor'a hore a soeufatsoe ke li-oxidants tsena. Kahoo haeba e hloka ho bleach masela a nylon, hangata ho sebelisoa sodium chlorite (NaCLO₂) kapa ntho e fokotsang bosoeu.
