Hoʻolauna i nā ʻano waiwai maʻamau o ka lole ʻaʻole i ulana ʻia PP
(1) Nā waiwai kino: ʻO ka lole ʻaʻole i ulana ʻole ʻia ʻo PP he mea ʻawaʻawa ʻole, ʻono waiu keʻokeʻo kiʻekiʻe crystalline polymer, ʻo ia kekahi o nā ʻano māmā o nā plastics āpau i kēia manawa.He paʻa loa ia i ka wai, a ʻo ka nui o ka absorption o ka wai i ka wai he 0.01% wale nō ma hope o 14h.ʻO ke kaumaha molekala ma kahi o 80,000 ~ 150,000, me ka formability maikaʻi.Eia nō naʻe, ma muli o ka emi ʻana o ka nui, ua maʻalahi nā huahana o ka pā mua i ka sag, a ʻālohilohi ka ʻili o nā huahana a maʻalahi ke kala.
(2) Mechanical waiwai: PP non-woven fabric he kiʻekiʻe crystallinity a me ka hana maʻamau, no laila, loaʻa iā ia nā waiwai mechanical maikaʻi loa.ʻOi aku kona ikaika, paʻakikī a me ka elasticity ma mua o ka PE kiʻekiʻe kiʻekiʻe (HDPE).ʻO ka hiʻohiʻona koʻikoʻi ʻo ke kuʻekuʻe ʻana i ka luhi (7 × 10 ^ 7) ʻO ka lua o ka wehe a me ka pani ʻana e piʻo me ka ʻole o ka pōʻino, a ua like ka coefficient friction maloʻo me ka nylon, akā ʻoi aku ka haʻahaʻa i ka nylon ma lalo o ka lubrication aila.
(3) Hana wela: ʻO ka lole PP non-woven maikaʻi ke kūpaʻa wela, ka helu hoʻoheheʻe he 164 ~ 170 ℃, a hiki ke hoʻomaʻemaʻe ʻia nā huahana ma kahi mahana ma luna o 100 ℃.Ma lalo o ka hana o waho ikaika, ʻaʻole ia e deform ma 150 ℃.ʻO ka mahana embrittlement he - 35 ℃, e kū ana ma lalo - 35 ℃, a ʻaʻole maikaʻi ka pale wela e like me PE.
(4) Paʻa kemika: ʻO ka lole i ulana ʻole ʻia ʻo PP he paʻa kemika maikaʻi.Ma waho aʻe o ka hoʻopau ʻia ʻana e ka waika, paʻa ia i nā mea hoʻokalakupua kemika ʻē aʻe.Eia naʻe, hiki i ka haʻahaʻa molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, a me nā mea ʻē aʻe ke hoʻoluliluli a pehu ka lole PP non-woven, a hoʻomaikaʻi ʻia ka paʻa kemika me ka piʻi ʻana o ka crystallinity.No laila, kūpono ka lole PP non-woven no ka hana ʻana i nā paipu kemika a me nā mea hana ʻo Rūsia a me Kina, me ka hopena anti-corrosion maikaʻi.
(5) Hana uila: He maikaʻi loa ka hana insulation kiʻekiʻe o ka lole i ulana ʻole ʻia.No ka mea aneane ʻaʻole e komo i ka wai, ʻaʻole pili ka hana insulation i ka haʻahaʻa.Loaʻa iā ia kahi helu dielectric kiʻekiʻe.Me ka piʻi ʻana o ka mahana, hiki ke hoʻohana ʻia e hana i nā huahana insulation uila wela.He kiʻekiʻe loa ka puʻupuʻu haʻihaʻi, a kūpono ia no nā mea uila.ʻO ke kūpaʻa uila maikaʻi a me ke kūpaʻa arc, akā kiʻekiʻe ka uila static, maʻalahi i ka wā kahiko ke launa pū me ke keleawe.
(6) ʻO ka pale ʻana i ka wā: ʻo nā lole i ulana ʻole ʻia ke maʻalahi loa i ke kukui ultraviolet, a hiki ke hoʻomaikaʻi ʻia ke kūpaʻa ʻelemakule ma ka hoʻohui ʻana i ka zinc oxide thiopropionic acid lauryl ester, carbon black e like me ka milky white filler, etc.
