Ua hoʻolauna nā mea hana kiʻekiʻe modulus polyethylene fiber ikaika kiʻekiʻe i kāna hana
(1) Kūleʻa hopena maikaʻi loa
ʻO ka pulupulu UHMWPE he fiber thermoplastic me ka mahana hoʻololi aniani haʻahaʻa.Loaʻa iā ia ka paʻakikī maikaʻi a komo i ka ikehu i ke kaʻina o ka deformation plastic.No laila, ʻoi aku ka maikaʻi o kāna mea hoʻohuihui i nā ʻano mechanical maikaʻi ma ke kiʻekiʻe o ke kānana a me ka wela haʻahaʻa.ʻOi aku ka kiʻekiʻe o ka hopena ma mua o ka fiber carbon, arylon fiber a me nā aniani fiber composites.ʻO ka hopena kikoʻī o ka ikehu absorption Et/P o ka UHMWPE fiber composite he 1.8, 2.6 a me 3 manawa o ka fiber carbon, aramide fiber a me E glass fiber, kēlā me kēia.ʻO ka hiki ʻana i ka pōkā o ka UHMWPE fiber composite he 2.5 mau manawa kiʻekiʻe ma mua o ka fiber aramide.ʻO ka ikaika o ka hopena o ka fiber UHMWPE ua aneane like me ka nylon, a ʻo ka hoʻohana ʻana i ka ikehu o ka fiber UHMWPE ma lalo o ka hopena kiʻekiʻe he pālua ia o ka PPTA fiber a me ka fiber nylon.He kūpono loa kēia hana no ka hana ʻana i nā mea pale pōkā.
(2) Hana kulou maikai
ʻO ka fiber polyethylene kiʻekiʻe ke kaumaha o ka molekala maikaʻi nā waiwai kuʻi a hiki ke hana i nā wili wili a me nā poʻo wili me ka haki ʻole.ʻAʻole maikaʻi nā waiwai wili o ke aniani aniani, ka fiber carbon a me ka arylon fiber.ʻO ka hoʻohālikelike ʻana i nā waiwai hana o nā fibers like ʻole e hōʻike ana he kiʻekiʻe ka molecular weight polyethylene ka ikaika hoʻopaʻa kiʻekiʻe a me ka ikaika hana apo, a ʻoi aku ka maikaʻi o ke apo UHMWPE fiber ma mua o ka fiber aramid.
(3) Ke kū'ē kū'ē o ka fiber
ʻO ka hana creep o ka fiber HSHMPE e pili ana i ka mahana a me ka ukana o ke kaiapuni hana.Hōʻike ʻia ka hana kolo o ka HSHMPE fiber ma 35 ℃ a me 1g / d load ma ka Papa 3. Ke hoʻohālikelike ʻia me ka fiber maʻamau, ʻoi aku ka maikaʻi o ka hana creep resistance o ka fiber HSHMPE.
(4) maikaʻi ka moisture kū'ē a me kemika corrosion kū'ē
Ma muli o ke ʻano kemika maʻalahi o ka polyethylene, maikaʻi ke kūpaʻa corrosion.ʻO nā huahana i hana ʻia i kēia fiber ʻaʻole e nalowale ko lākou ikaika ma ka hoʻopili ʻana me nā waikawa, alkalis, wai kai lepo, a me nā mea ʻē aʻe. i mea e pale pono i ka erosion o ka wai molekele a me kemika reagents, no laila, he maikai solvent solubility kū'ē.Hoʻopaʻa piha ʻia ka ikaika o nā kiko kikoʻī i ka wā i hoʻopaʻa ʻia no ka hapalua makahiki i loko o nā ʻano media like ʻole, e like me ka wai, ka aila, ka waikawa, a me nā haʻina kumu.Mālama ka Spectra fiber i kona ikaika ma hope o ka hoʻokomo ʻia ʻana i loko o ka wai a hiki i ʻelua makahiki a kūʻē hoʻi i ka corrosion biological.Papa 1 -- 8 ka papa inoa o ka paa ikaika o Spectra fiber a me Kevlar fiber i loko o na media kemika.UHMWPE fiber macromolecular kaulahao ʻaʻole i loaʻa i kekahi apo aromatic, amino pūʻulu, hydroxyl pūʻulu a i ʻole nā hui kemika ʻē aʻe i hiki ke hoʻouka kaua reagent, kiʻekiʻe ka crystallinity, no laila e mālama ʻia ka ikaika i nā ʻano caustic ʻē aʻe ma mua o 90%, ʻoiai ʻo aramid fiber i loko. ʻakika ikaika, emi nui ke kumu ikaika.
(5) E hoʻohana i ka pale
Ke emi nei ka pale ʻana o ka mea me ka modulus nui, akā no ka UHMWPE fiber, ʻo ke ʻano ke kū'ē, no ka haʻahaʻa haʻahaʻa o ka friction, no laila ke kūpaʻa kiʻekiʻe.ʻO ke kaula fiber Spectra900PE he 8 mau manawa ke kiʻekiʻe o ka haki ʻana i ka helu N ma mua o ka fiber aramid, a ʻoi aku ka kiʻekiʻe o ka lole a me ke kulou ʻana i ka ikaika luhi ma mua o ka fiber aramid.Ma muli o kāna hana maʻalahi, loaʻa iā ia kahi manaʻo noi maikaʻi i ka ʻoihana.Hoʻopaʻa kūʻē i ka UHMWPE i ka lei palaki, ʻoi aku ka nui o nā manawa ma mua o ke kila kalapona, ʻo Huang Gang ke pale ʻana i ka lole, ʻoi aku ka nui o kona pale ʻana ma mua o ka polyethylene maʻamau, a me ka nui o ka molekala pili kiʻekiʻe, ʻoi aku ka maikaʻi o ka hana pale ʻana, akā. ma hope o ka hiki ʻana o ka molekala pili i kahi waiwai, ʻaʻole loli hou kona pale ʻana me ka nui o ka molekala pili kiʻekiʻe.
(6) Hoʻopili uila a me ka pale māmā
ʻOi aku ka kiʻekiʻe o ka hoʻouna ʻana o nā huila UHMWPE fiber i hoʻoikaika ʻia i nā nalu radar ma mua o nā mea i hoʻohui ʻia i ka fiber glass no ka haʻahaʻa haʻahaʻa o ka dielectric mau a me nā waiwai poho dielectric a me ka liʻiliʻi o nā nalu radar i ʻike ʻia.ʻO ka dielectric mau o nā mea polyethylene a me ka waiwai hoʻopakele mana he liʻiliʻi, kūpono ia no ka hana ʻana i nā radomes like ʻole.Eia kekahi, ʻo ka ikaika dielectric o UHMWPE e pili ana i 700kV / mm, hiki ke hoʻomalu i ka hoʻololi ʻana o ke arc a me ka uila uila.
ʻOiai ma hope o ka hoʻomālamalama ʻana o 1500h, ʻo ka nui o ka paʻa ʻana o ka UHMWPE fiber ma kahi o 68 pakeneka, aʻo nā mea ʻē aʻe ma lalo o 50 pakeneka.
