Letlapa la Polyethylene PE300 - HDPE
Tlhaloso:
HDPE ha e na monko, ha e chefo, e ikutloa joaloka boka, e na le khanyetso e ntle ea mocheso o tlase, botsitso bo botle ba lik'hemik'hale, letlapa la PE le khona ho hanyetsa boholo ba li-acids le alkalis, ha le qhale li-solvents ka kakaretso mocheso oa kamore, ho kenngoa ha metsi a tlaase, ho kenngoa ha motlakase Ho sebetsa hantle le ho bonolo. tjheseletsa.Boima bo tlase (0.94 ~ 0.98g / cm3), boima bo botle, ho otlolla hantle, ho kenya motlakase hantle le dielectric, ho kenella ha mouoane o tlase, ho monya metsi a tlase, botsitso bo botle ba lik'hemik'hale, matla a matle a thata, bohloeki bo se nang chefo.
Tshebetso:
| Ho hanyetsa hantle ho apara le ho koala motlakase |
| Boima bo phahameng le ho tiea, matla a matle a mochine |
| Ho thatafala, matla a tsitsitseng le thepa ea ho hahaba li molemo ho feta tsa ldpe |
| Mocheso o motle le ho hanyetsa serame, mocheso o sebetsang o fapaneng -70 ~ 100 ° C |
| botsitso bo botle ba lik'hemik'hale, mocheso oa kamore, ha bo qhibilihe ka har'a mokelikeli leha e le ofe, ho bola ha acid, alkali le letsoai. |
