PE lisebelisoa tsa cable

PE ke motsoako oa polyethylene, haholo-holo o arotsoe ka polyethylene e phahameng (HDPE), polyethylene ea mahareng (MDPE), polyethylene e tlaase (LDPE) le polyethylene e tlaase e tlaase (LLDPE).

1.HDPE ke mofuta o phahameng oa crystallinity, non-polar thermoplastic resin e hlahisoang ke ethylene copolymerization. Ponahalo ea HDPE ea mantlha e bosoeu ba lebese, 'me e khanya ho isa bohōleng bo itseng karolong e fokolang. E na le khanyetso e babatsehang ho lik'hemik'hale tse ngata tsa malapeng le tsa indasteri, 'me e ka hanela ho bola le ho qhibiliha ha li-oxidants tse matla (concentrated nitric acid), acid le alkali salts le solvents organic (carbon tetrachloride). Polymer ha e monye mongobo 'me e na le ho hanyetsa metsi hantle ho mouoane, e ka sebelisoang bakeng sa tšireletso ea mongobo le ea metsi.

2.MDPE e khetholloa ke ho hanyetsa khatello ea kelello ea tikoloho le ho boloka matla a nako e telele. Boima bo lekanang ba MDPE ke 0.926-0.953, crystallinity ke 70% -80%, karolelano ea boima ba molek'hule ke 200,000, matla a thata ke 8-24 mpa, bolelele nakong ea khefu ke 50% -60%, mocheso o qhibilihisang 126-135 ℃, 'me sekhahla sa ho phalla ke 0.1-35 g / 10 metsotso. Thermal deformation mocheso (0.46 mpa)49-74 ℃.

3. Polyethylene e fokolang haholo ke mofuta o bobebe ka ho fetisisa oa resin ea polyethylene. Ha ho bapisoa le polyethylene e phahameng haholo, crystallinity ea eona (55% -65%) le ntlha ea ho nolofatsa (90-100 ℃) e tlase. E na le bonolo bo botle, ho atolosoa, ho pepeseha, ho hanyetsa serame le ho sebetsa hantle. Botsitso ba eona ba lik'hemik'hale bo botle, bo khona ho mamella tharollo e nang le asiti, alkali le letsoai; Insulation e ntle ea motlakase le ho kenella ha khase; Ho monya metsi a tlase; Ho bonolo ho chesa. Thepa e bonolo, e na le extensibility e ntle, ho kenya motlakase, botsitso ba lik'hemik'hale, ts'ebetso ea ts'ebetso le ho hanyetsa mocheso o tlase (ho hanyetsa -70 ℃).

4. Ha e bapisoa le LDPE, LLDPE e na le melemo ea matla a phahameng, ho tiea hantle, ho tiea ho matla, ho hanyetsa mocheso, ho hanyetsa serame, joalo-joalo, LLDPE e boetse e na le khatello e ntle ea khatello ea kelello ea tikoloho, ho hanyetsa meokho le thepa e meng, 'me e ka hanela acid, alkali, organic solvents joalo-joalo.

Tlhokomeliso: Likaroloana tsa polasetiki tsa PE li sebelisoa haholo mme li hloka ho etsoa ho latela litlhoko tsa bareki maemong a fapaneng.
