Masela entsoe ka poliester. Tlhahiso ea likhoele poliester

Lik'hemik'hale tlhahiso ea - e le mohloli e khōlō ea leruo la motho. Ka mor'a hore tsohle, tsohle ho tswa ho lintho tse ba ntlo ea ho liaparo, o phethile 'me le hlahisa ka lebaka la saense e ba.

A karolo ea khethehileng ho sebelisoa masela a fapaneng lik'hemik'hale, eo fumana kopo masimong tse ngata tsa theknoloji e saense le indasteri.

Classification tsa likhoele lik'hemik'hale

e entsoeng ke motho likhoele tsohle di ka arotsoe ka lihlopha tse peli tse khōlō.

1. Maiketsetso - ba elang tse thehiloeng polymer tsa tlhaho, empa ho tshwara le bōpa ka ho toba linaleli le hlaha le ho kenya letsoho ha mekhoa physicochemical.
2. Maiketsetso - likhoele tse ka ho toba ka liteko tsa laboratori (liindasteri) maemo. Ba li thehiloe tloaelehileng tlaase metsoako ea limolek'hule boima hore ba fetoloa macromolecules ka liphetoho molekyler.

Le eena, a maiketsetso le maiketsetso likhoele le bona ba na tlhophiso bona le mehlala. Nahana ka e 'ngoe bakeng sa disampole maiketsetso.

Ba ka arotsoe ka lihlopha tse peli tse khōlō. Mohaho ka sehloohong tsa ketane k'habone, le mekhoa ea ho theha likamano tsa batho.

1. Carbochain ea likhole tse iketselitsoeng. The ketane ka sehloohong e hahiloeng ka tieo k'habone liathomo, ya kokangana ke tloaelehileng litlamo Sigma-mofuta. haholo palo e khōlō ea disampole ka ngotsoe ke sehlopha sena. Mohlala, polyacrylonitrile, nhua polyethylene, polyvinylchloride, polypropylene, polyvinyl joala.
2. Heterochain ea likhole tse iketselitsoeng. Tšoauoa ka ho akarelletsa le k'habone ka heteroatoms macrochain - naetrojene, sebabole, phosphorus le ba bang. sehlopha sena se akarelletsa ho sebelisoa masela a joalo: poliester, kettle, polyamide.

Ha re bua ka tšebeliso ea eona ho indasteri e Textile, boleng tse hlalositsoeng ke baemeli ba fapaneng. Kahoo, faeba maiketsetso le lintho tse ngata ho hlokehang haholo bakeng sa liaparo, line ea boleng bo bethe, lithaole le lintho tse ling line ea lelapa. Leha ho na le ntle le mabaka a, ha lesela joalo e sebelisoa ka tsebo.

Maiketsetso lik'hemik'hale likhoele, ka lehlakoreng le leng, tse ling tse ngata tshwanelanang ka kaho, le boenjiniere, indasteri, ho ena le ho feta ka lapeng. A shebisisa ka masela hantle poliester li phutholohe ho bona le dikopo.

Masela entsoe ka poliester: a kakaretso kakaretso

Ho tswa ho lik'hemik'hale maikutlo, sehlahiswa sena - ena ke lebaka la sebelisana tsa terephthalic acid e C ₈ H ₆ O ₄ le ethylene glycol, ka joala C dihydric ₂ H ₆ O _2. Ka lebaka leo, e rarahaneng molekyler itsoara joang ka bopa ka kristale hlakile kapa o mosoeu, o na thepa ea bohlokoa - e tiileng e qamathelang. Ho etsa joalo ba mocheso bona. Ho ka ba lokisetsa ho ena e khethehileng, e thehiloe likhoele ka kotloloho ho tswa ho lithethefatsi le.

The qhibiliha mocheso ea thepa tsena holimo 260 ⁰ C. Sena se etsa hore ba ho bonolo ho e sebelisa bakeng sa merero ea liindasteri. Ho na le a 'maloa a thepa e khethehileng ena ke likhoele tse joalo.

1. Maiketsetso poliester yarns ka mamella ditharollo tsa acid, alkalis.
2. Ha ho qhala ka metsi, solvents, mofuta manyolo.
3. Ke kobo e, ho e hoo e batlang e sa itšoareng motlakase.
4. Products entsoe ba matla, tsoarellang haholo ebile ea tšepahala.

Ho a maiketsetso a ka ho feletseng ka lintho tsa tlhaho, yarns tsena le phahametse ka litsela tse ngata bakeng sa botekgeniki le Textile litšobotsi tsa batho ba bangata likhoele e entsoeng ke motho.

mekhoa ho hlahisoeng

Ho ea ka tlhaloso e boletsoeng ka holimo e lokela ho ba ka poliester difeme terephthalic acid e. Leha ho le joalo, tsa lona thepa 'meleng a batla a le tšitiso bakeng sa lumellana le ho ka potlako molekyler itsoara joang ka ethylene glycol, kahoo, ho ha e sebelisoa ka foromo e hloekileng, e le Ester e. lebitso la lona - dimethyl terephthalic acid e Ester tsa lebitso tšoanang, khutsufalitsoe ka DMT.

Ka lebaka leo, tlhahisong ea poliester faeba e entsoe ka mehato e 'maloa tse latellanang tsa lik'hemik'hale:

• ho kena moea ka motsoako oa esters ba le para-xylene, i.e. ba lokisetsa ho ea qalang thepa;
• esterification, ke hore, sa tlhahiso ya Ester DMT;
• Distillation le tlhoekiso ea sehlahiswa sephetho;
• DMT recrystallization ho fumana lintho tse bonahalang bo hloekileng.

Lokisetsa ho ea ka ena lithethefatsi sekemeng loketse bakeng sa ho kena ka potoloho ea latelang a itšoare hore fella 'me e be poliester (poliester). Ho nka sebaka ka mekhahlelo mabeli a ka sehloohong.

1. Transesterification fumana DMT le ethylene glycol. Sephetho - diglycol le tlaase polyesters limolek'hule boima.
2. Polycondensation fumanweng ka mohato oa pele ke pakeng tsa lihlahisoa. Phello ke polietilentereftalatat viscous.

Hona joale ho ke ke ho fihlela ho lehlakoreng le botekgeniki. ntho e feta har'a e khethehileng tse nyenyane spinneret prodavlivaya joaloka, 'me kahoo likhoele lokisitseng. Ka Cooling ba crystallize. sebetsa ka ho eketsehileng e ntša, le tlhoekiso le colouring.

lebitso la lintho tse bonahalang

linaheng tse sa tšoaneng 'me li likhoele tsena li sebelisoa. Poliester maiketsetso likhoele ka e mong le e boemo a lebitso la eona, kahoo ba le e ngata synonymes. A re ke re bone hore na ba leng sona.
