Phapang ke efe pakeng tsa mekotla ea lijo le mekotla e tloaelehileng ea polasetiki?

1. Polyethylene: Karolo e ka sehloohong ke resin ea polyethylene, 'me palo e nyenyane ea lubricant, botsofali le lisebelisoa tse ling li kenngoa.Polyethylene ke boka bo bosoeu bo bosoeu bo tiileng, bo sa nkheng, bo sa nkheng.HDPE e arotsoe ka polyethylene e phahameng haholo, polyethylene e tlaase-tlaase le polyethylene e nang le linear e tlaase-tlaase ho ea ka morphology, dikahare le sebopeho sa ketane ea polymer.
Polasetiki ea polyethylene hangata e bitsoa HDPE ea khatello e tlase.Ha ho bapisoa le polyethylene e tlaase-tlaase le LLDPE, lipolasetiki tsa polyethylene li na le mocheso o phahameng oa ho hanyetsa, ho hanyetsa abrasion, mouoane oa metsi hydrophilicity le khatello ea kelello ea crack libakeng tsa tlhaho.Ho phaella moo, polasetiki ea polyethylene e na le matla a matla a dielectric, ho hanyetsa tšusumetso le ho hanyetsa serame.E loketse lihlahisoa tse se nang letho (joalo ka libotlolo tsa khalase, libotlolo tsa sesepa), ho bopa ente, ho bopa ente le liindasteri tse ling.
Linear low-density polyethylene (LINEARLOWDENSYPOYETHYLENE, LLDPE) ke polymer e hlahisoang ke polymerization ea ethylene le palo e nyane ea olefin e tsoetseng pele ka boteng ba catalyst.Ponahalo ea eona e tšoana le ea polyethylene e tlaase-tlaase, empa gloss ea eona e ntle e ntle, e nang le mocheso o tlaase oa mocheso le Modulus e phahameng, ho hanyetsa ho khumama, ho hanyetsa khatello ea kelello ea fatše, mocheso o tlaase oa tšusumetso matla a khatello le melemo e meng.
E sebelisoa haholo-holo bakeng sa ho bōptjoa ha ente, extrusion, ho phunya le mekhoa e meng ea ho bōpa ho hlahisa lifilimi, litlhoko tsa letsatsi le letsatsi, liphaephe, lithapo le likhoele.
2. Polypropylene: Karolo e ka sehloohong ke resin ea polypropylene, e nang le khanya e phahameng le transmittance e khanyang.Ts'ebetso ea ho tiisa mocheso e mpe ho feta PE, empa e molemo ho feta lisebelisoa tse ling tsa polasetiki.
1. Ts'ebetso ea thibelo e molemo ho feta PE, matla a eona, boima le ho tiea ho feta PE;
2. Bophelo bo botle le polokeho li phahametse lipapali
3. E na le ho hanyetsa mocheso o babatsehang 'me e ka sebelisoa nako e telele mocheso oa likhato tse 100 tsa Celsius, empa ho hanyetsa ha eona ho batang ho ntlafatsa ts'ebetso ea HDPE mme e fetoha brittle ho -17 degrees Celsius.
Mokotla oa ho paka o entsoeng ka filimi ea polasetiki o phahametse platinum, lisebelisoa tse tala tse pepeneneng le lisebelisoa tse thibelang ho taboha ka lebaka la ho hanyetsa le ho hanyetsa mongobo, empa phello ea khatiso ea liphutheloana e fokola 'me litšenyehelo li tlaase.E ka sebelisoa bakeng sa ho paka ka morao ea li-lollipops le li-snacks.E ka etsoa ka mocheso oa lijo shrinkable filimi packaging mokotla mocheso shrinkable filimi, tse kang lijo le lijo polasetiki ambalaji mekotla le tse ling tse composite ambalaji mekotla.
3. Polystyrene: Polymer e nang le styrene monomer e le karolo e ka sehloohong.Boitsebiso bona bo pepenene ebile boa benya.
1. Ho hanyetsa mongobo ho mpe ho feta PE, botsitso ba lik'hemik'hale bo tloaelehile, boima bo phahame, empa brittleness e kholo.
2. Ho hanyetsa mocheso o tlase o motle, empa ho hanyetsa mocheso o fokolang, ho ke ke ha feta 60≤80℃.
3. Ntho e ntle ea tšireletso.
