ʻOi aku ka ikaika o ka pale ʻana o ka hapa nui o nā plastics i ka ʻakika, alkali, paʻakai, a me nā mea ʻē aʻe ma mua o nā mea metala a me kekahi mau mea inorganic, a kūpono loa ia no nā puka a me nā puka makani, nā papahele, nā paia, a me nā mea ʻē aʻe i nā mea kanu kemika; hiki ke hoʻoheheʻe ʻia nā thermoplastics e kekahi mau mea hoʻoheheʻe organik, ʻoiai ʻaʻole hiki ke hoʻoheheʻe ʻia nā plastics thermosetting, akā hiki ke pehu iki. Loaʻa i nā plastics ke kūpaʻa maikaʻi i ka wai o ke kaiapuni, haʻahaʻa ka omo wai, a hiki ke hoʻohana nui ʻia i nā papahana pale wai a me ka makū.
Paipu PE(paipu HDPE) i hana ʻia me ka polyethylene ma ke ʻano he mea maka nui, me ka hoʻohui ʻana i nā antioxidants, ka ʻeleʻele kalapona a me nā mea kala. Hōʻike ʻia ia e ka haʻahaʻa haʻahaʻa, ka ikaika kikoʻī kiʻekiʻe, ke kūpaʻa haʻahaʻa maikaʻi a me ka paʻakikī, a hiki i ka mahana embrittlement ke piʻi i -80 °C.
Paipu PE plastikhiki ke hana ʻia a hoʻokumu ʻia e nā ʻano hana like ʻole e hana i nā huahana like ʻole e like me nā kiʻiʻoniʻoni, nā pepa, nā paipu, nā ʻaoʻao, a pēlā aku; a he kūpono ia no ka ʻoki ʻana, ka hoʻopaʻa ʻana a me ka hana "welding". He maʻalahi ke kala ʻana i ka palaki a hiki ke hana ʻia i nā kala ʻōlinolino; hiki ke hana ʻia ma ka paʻi ʻana, ka electroplating, ka paʻi ʻana a me ke embossing, e hoʻolilo ana i nā plastics i waiwai i nā hopena hoʻonaninani.
ʻO ke kūpaʻa wela oNā paipu PE plastikʻaʻole kiʻekiʻe loa. Ke kau ʻia i nā ukana ma nā mahana kiʻekiʻe, palupalu a hoʻololi ʻia, a palaho a hōʻino paha. ʻO ka mahana hoʻololi wela o nā thermoplastics maʻamau he 60-120 °C, a he kakaikahi wale nō nā ʻano like ʻole e hiki ke hoʻohana ʻia no ka manawa lōʻihi ma kahi o 200 °C. . He maʻalahi ke ahi a puhi mālie paha kekahi mau plastics, a he nui ka uahi ʻawahia e hana ʻia i ka wā e puhi ana, e hōʻeha ana i nā mea i ka wā e puhi ai nā hale. ʻOi aku ka nui o ke coefficient o ka hoʻonui linear o ka plastic, ʻo ia hoʻi he 3-10 mau manawa ʻoi aku ka nui ma mua o ka metala. No laila, nui ka hoʻololi ʻana o ka mahana, a ua maʻalahi ka hōʻino ʻia o ka mea ma muli o ka hōʻiliʻili ʻana o ke kaumaha wela.
Ma muli o kāna hana haʻahaʻa haʻahaʻa maikaʻi loa a me ka paʻakikī, hiki iā ia ke kū'ē i ka pōʻino o ke kaʻa a me ka haʻalulu mechanical, ka hana hau-hoʻoheheʻe a me nā loli koke i ke kaomi hana. No laila, hiki ke hoʻohana ʻia nā paipu wili no ka hoʻokomo ʻana a i ʻole ke kūkulu ʻana i ka palau, kahi mea kūpono no ke kūkulu ʻana a haʻahaʻa hoʻi ke kumukūʻai ʻenekinia; He laumania ka paia o ka paipu, he liʻiliʻi ke kū'ē ʻana o ke kahe waena, he haʻahaʻa ka hoʻohana ʻana i ka ikehu o ka mea lawe, a ʻaʻole ia i hoʻopōʻino ʻia e nā hydrocarbons wai i loko o ka mea lawe.
