ʻAʻole ʻōlelo ʻia nā ʻeke pahu no ka hoʻohana lōʻihi ʻana i nā wahi wela kiʻekiʻe a haʻahaʻa

ʻO ka ʻeke pahu kahi ʻano o ka ʻike ʻana o ka pahu pahu, ʻo ia kekahi ʻano o ka pahu lawe lawe maʻalahi.Hoʻohana nui ʻia i ka meaʻai, ka palaoa, ka lāʻau lapaʻau, kemika, nā huahana mineral a me nā pauka ʻē aʻe, granular, poloka i ka lawe ʻana a me ka hoʻopili.Nui nā ʻano ʻeke pahu, ʻeke lole i uhi ʻia maʻamau, ʻeke lole resin, ʻeke hui a pēlā aku.No laila, ma ke ʻano o ke kaiapuni e hoʻohana ʻia ai nā ʻeke pahu?He aha ka mahana e hiki ai i nā ʻeke pahu ke kū?E hahai pū me Xiaobian e hoʻomaopopo iā ia!

ʻeke pahu mea maka

ʻO ka pahu he pahu palaki maʻalahi me ka polypropylene a me ka polyethylene resin ma ke ʻano he kumu waiwai, ʻo ka nui o ia mea ma lalo o 3m3 a ʻoi aku ka nui o ka lawe ʻana ma mua o 3 tons.

polypropylene

Ka helu heheʻe 165 ℃, palupalu ma kahi o 155 ℃;

Aia ka mahana hana mai -30°C a i 140°C.

Hiki iā ia ke pale i ka ʻino o ka waikawa, alkali, ka paʻakai paʻakai a me nā ʻano mea hoʻoheheʻe kūlohelohe ma lalo o 80 ℃, a hiki ke decompose ma lalo o ka wela kiʻekiʻe a me ka oxidation.

politena

ʻO ka helu heheʻe 85 ℃ a 110 ℃, me ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi loa;

Hiki i ka mahana hoʻohana ke piʻi i -100 ° C a -70 ° C, kūpaʻa kemika maikaʻi, kū'ē i ka nui o ka waikawa a me ka erosion base (ʻaʻole kū i ka waikawa me nā waiwai oxidizing)

ʻeke pahu hoʻohana wela?

He aha ke ʻano wela o nā ʻeke pahu i hana ʻia me ka polypropylene a me ka polyethylene?

Wahi a ke kūlana aupuni GB/T10454-2000, ʻo ka mahana hoʻāʻo kūʻē kūʻē o ka pahu pahu he -35 ℃.

E kau i ka ʻeke pahu i loko o kahi pahu wela mau ma mua o 2 mau hola, a laila e pelu i ka huahana hoʻāʻo i ka hapalua a 180 degere e nānā inā ua pōʻino ka mea substrate, māwae a me nā kūlana ʻē aʻe.

ʻO ka mahana ho'āʻo pale wela he 80 ℃.

E kau i ka ukana o 9.8N i ka huahana ho'āʻo a waiho i loko o ka umu ma 80 ℃ no 1h.Ma hope koke o ka lawe ʻana i ka huahana hoʻāʻo, e hoʻokaʻawale i nā ʻāpana hoʻāʻo ʻelua a nānā i ka ʻili no ka hoʻopili ʻana, nā māwae a me nā kūlana ʻē aʻe.

Wahi a ke kūlana hoʻāʻo, hiki ke hoʻohana ʻia ka ʻeke pahu i loko o ke kaiapuni o -35 ° C a 80 ° C, akā ʻaʻole ia e ʻōlelo ʻia no ka hoʻohana lōʻihi i nā wahi wela a haʻahaʻa.
