Ka hoʻohālikelike ʻana i nā mea hoʻoheheʻe EPDM a me nā mea ʻala silicone

Hiki ke hoʻohana ʻia ka lāʻau EPDM a me ka lāʻau silicone no ka paipu hoʻoemi anuanu a me ka paipu wela wela.He aha ka ʻokoʻa ma waena o kēia mau mea ʻelua?

1. Ma ke ʻano o ke kumukūʻai: ʻoi aku ka liʻiliʻi o nā mea hoʻoheheʻe EPDM ma mua o nā mea silicone rubber.

2. Ma keʻano o ka hanaʻana:ʻOi aku ka maikaʻi o ka silicone rubber ma mua o ka EPDM.

3. Ma ke ʻano o ka pale wela: ʻoi aku ka maikaʻi o ka pale ʻana i ka wela, ʻoi aku ka maikaʻi o ka pale ʻana o ka EPDM i ka mahana o 150 ° C, a ʻo ka lāʻau silicon he 200 ° C.

4. Kūleʻa i ka wā: ʻOi aku ka maikaʻi o ka ethylene-propylene rubber i ka wā, a ʻo ka lāʻau ponoʻī he mea aloha kaiapuni, akā ma kahi ʻano haʻahaʻa, ʻoi aku ka liʻiliʻi o ka ethylene-propylene rubber e hoʻohua i ka bacteria.

5. Shrinkage lākiō hoʻonui lākiō: i kēia manawa, ʻoi aku ka kiʻekiʻe o ka lākiō hoʻohaʻahaʻa o ka paipu hoʻohaʻahaʻa silikoni ma mua o ka EPDM anuanu.

6. ʻO ka ʻokoʻa o ka puhi ʻana: I ka wā e ʻā ai, e hoʻokuʻu ka silicone rubber i ke ahi ʻālohilohi, aneane ʻaʻohe uahi, ʻaʻohe ʻala, a me ke koena keʻokeʻo ma hope o ke ahi ʻana.EPDM, ʻaʻohe mea like.

7. Ma keʻano o ka haehaeʻana a me ke kū'ēʻana i ka puncture: ʻOi aku ka maikaʻi o ka EPDM.

8. Nā mea'ē aʻe: He ozone maikaʻi a me ka ikaika kiʻekiʻe ka Ethylene-propylene rubber;kiʻekiʻe paʻakikī a me ka haʻahaʻa haʻahaʻa haʻahaʻa brittleness;ʻO ka silica gel ka elasticity maikaʻi a me ka hana haʻahaʻa haʻahaʻa maikaʻi;ozone maʻamau, ikaika haʻahaʻa!
