Pom vs.nylon

Abstract: Lisebelisoa tsa Pom le lisebelisoa tsa nylon ke lisebelisoa tsa polymer ka bobeli, empa li na le likarolo tse fapaneng tsa polymer tsena, thepa le ts'ebeliso

1. Sebopeho sa lik'hemik'hale

Boitsebiso bo pompo, hape bo tsejoang e le polyoxethylene, ke kristale ea limolek'hule tsa limolek'hule tsa hae Tokisetso ea lifolakha tsa formalldehlde li-silent tsa pom li khafetsa, li theha libaka tsa kristale. Libaka tsena tsa kristale li fa Pompo e phahameng haholo, matla a phahameng mme a apara.

Lintho tsa nylon, tse tsejoang hape e le polyamide, ke khomo ea mang ea amelikalaneng eo li thetsoang limolek'hule. Majoe a limolek'hule tsa amino acid ka lisebelisoa tsa nylon li hlophisoa ka mokhoa o laetsoeng, ho theha libaka tsa amorphous. Libaka tsena tsa Amorphous li fana ka lisebelisoa tsa nylon hantle kapa li-elasticity.

2. Ts'ebetso

LITLHAKISO TSA 'Mele

Lintho tse itlhophisang li thata, li apere matla a phahameng, li hlophisehile ka nako e tšoanang, li hlophisehile ka nako e ts'oanang, thepa ea pom e na le thepa e ntle ea motlakase le botsitso ba bokhabane 'me bo ka sebelisoa ho etsa mekhatlo ea elektroniki, lihokelo, joalo-joalo

Lisebelisoa tsa nylon li na le maemo le maemo , cable sheath, joalo-joalo

Boitšoaro ba Boikarabello

Melemo ea mecha ea lisebelisoa ea lisebelisoa tsa pom e kenyelletsa boholo bo phahameng, ba apereng matla a phahameng, litho tsena li li sebelisetse ho etsa likarolo tse ngata tse u romang. Mohlala, lisebelisoa tsa pom li ka sebelisoa ho etsa lisebelisoa tsa mochini tse tataisang tse tataisang lijana, tse behang litoro, jj.

Melemo ea mecha ea lisebelisoa ea thepa ea nylon e kenyelletsa ho fetoha le maemo, ho hanyetsa le ho hanyetsa tšusumetso e matla. Lintho tsena li li sebelisoa haholo ho etsa tlhahiso e hlokang ho e mamella le ho khumama. Mohlala, lisebelisoa tsa nylon li ka sebelisoa ho etsa li-hostes tse feto-fetohang, mabanta a khang, likarolo tsa auto, jj.

3. Lylon o na le thepa e ntle e theko e phahameng haholo ea ho hanyetsa, ho hanela ho hanyetsa, ho hanana le ho hanyetsa mocheso.

1) thepa e ntle e ntle. Nylon e na le matla a phahameng a matla le ho ba thata haholo.

2) Ho ikhatholla hamonate le ho hanyetsa. Nylon o na le thepa e ntle ea boithati le e nang le monko o monyane oa likhohlano. E le karolo ea phetisetso, e na le bophelo bo botle ba tšebeletso.

3) Ho hanyetsa mocheso o monate oa mocheso. Li-krinon lickstalline e joalo ka nylon 46 li na le mocheso o phahameng haholo oa mocheso mme o ka sebelisoa nako e telele ka la 150 ° C. Kamora nylon e matlafala ka fiber ea khalase, mocheso oa eona o khopisang o fihla ka holimo ho 250 ° C.

4) thepa e ntle ea tlhatlhobo ea eleklose. Nylon e na le khanyetso e phahameng ea ho hanyetsa le ho senya maikutlo a boleng bo holimo, e e etsa lingoliloeng tse ntle tsa motlakase.

5) Boemo ba leholimo bo botle ba leholimo bo botle ba leholimo.

6) Ho kena ka metsing. Nylon e na le monyaka o phahameng oa metsi, 'me metsi a lutseng a ile a tlala ho feta 3%, e amang botsitso ba likarolo tse itseng ho isa tekanyong e itseng.

4.POM, Polyformalddehyde, e boetse e tsejoa e le "tšepe ea morabe", "ho molemo ho feta morena kobo!"

1) matla le matla a phahameng;

2) Matla a maano a phahameng ka ho fetisisa;

3) Ho hanyetsa hantle ha tikoloho le ho hanyetsa li-solyts tsa manyolo;

4) Ho hanyetsa matla ho litšusumetso tse phetoang.

5) Matla a motlakase a motlakase;

6) Matla a ho hlaphoheloa;

7) Boithati bo apara hantle le ho roala bo botle;

8) ho tsitsa haholo ka mokhoa o motle;

9) Mocheso o sebetsang o tlase haholo, ke 70 ~ 80 ℃;

10) Ha ho na sehlopha sa ho khutlela lelato; Ha a hanela hydrolysis.

Likhetho tsa ho etsa kopo:

(1) apara khanyetso:

Ha sehlahisoa sa hau se sena litlhokahalo tse ngata mme ho batla feela ho roala pompo, ho khetha. Hobane pom e molemo ho feta nylon.

(2) o hanyetsana le mocheso o thibelang:

Ha sehlahisoa sa hau se hloka ho halefa 'me u na le litlhoko tsa mocheso, u lokela ho khetha nylon, hobane pompo e hana ho ikhula ebile ha e khone ho amohela litlhoko tsa hau.

(3) Ho hanela ho ama le ho ikopanya le metsi:

Ha sehlahisoa sa hau se ka etsoa khafetsa, se hloka ho hanyetsa tšusumetso, 'me se kopana le metsi, joalo ka sejo sa tan, hobane Pom ha e hanyetse hydrolysis, leha e le hantle ho hanyetsa.

(4) Ho thata le ho apara khanyetso:

Ha o hloka ho thatafala hantle, theko e tlase, 'me ha ho litlhoko tsa mocheso, khetha pom.

(5) ho thatafala le ho ba thata:

Nylon e loketse lisebelisoa tse hlokang ho ba thata le ho ba thata.

(6) mojaro:

Bakeng sa meroalo e mahareng le e tlase, khetha pom.
