ʻElua mau hoʻohana nui o nā olonā polypropylene i loko o ka sima:
1) Kāohi i nā māwae ʻūlū palaki i loko o ka sima.
I ka wā o ke kaʻina hana hoʻonohonoho a me ka paʻakikī ʻana o ka sima, hiki i ka nalowale ʻana o ka wai o ka ʻili ke alakaʻi i ka emi ʻana o ka plastic a me nā māwae. ʻO ka hoʻohui ʻana i nā olonā polypropylene i ka sima hiki ke pale i kēia mau māwae. Ma muli o ka modulus elastic haʻahaʻa o nā olonā polypropylene i hoʻohālikelike ʻia me ka sima paʻakikī, ua kaupalena ʻia ka hoʻomaikaʻi ʻana i ke kū'ē ʻana i ka māwae (ka māwae i hoʻokumu ʻia e ke kaumaha wela a i ʻole ka ukana mechanical) o ka sima paʻakikī, a ʻaʻole koʻikoʻi ka hoʻomaikaʻi ʻana i ka ikaika tensile a me ka flexural, kahi i loaʻa ai kekahi kekelē o ka hoʻomaikaʻi ʻana i ka paʻakikī o ka sima.
2) Hoʻomaikaʻi i ke kūpaʻa ahi o ka sima paʻakikī. Ma lalo o ka hana o ka mahana kiʻekiʻe, e palupalu mua nā olonā polypropylene a puhi ʻia, e hana ana i nā pores he nui i loko o ka sima. Hiki ke hoʻokuʻu ʻia ka wai i mahu ʻia e ka mahana kiʻekiʻe i loko o ka sima ma kēia mau pores, e pale ana i ka hoʻokumu ʻia ʻana o ke kaomi kiʻekiʻe kūloko ma muli o ka mahu ʻana o ka wai a me ke kumu o ka pahū ʻana o ka sima, a pēlā e hoʻomaikaʻi nui ai i ka manawa kūpaʻa ahi a me ke ʻano o ka sima.
Hiki ke hoʻokaʻawale ʻia nā olonā polypropylene i nā olonā lōʻihi, nā olonā pōkole, nā lole i ulana ʻole ʻia spunbond, nā lole i ulana ʻole ʻia i hoʻoheheʻe ʻia, a pēlā aku.
(1) Māmā
ʻO ka nui o ke olonā polypropylene he 0.90-0.92 g/cm, ʻo ia ka māmā loa ma waena o nā olonā kemika āpau, 20% māmā ma mua o ka nylon, 30% māmā ma mua o ka polyester, a 40% māmā ma mua o nā olonā viscose. No laila, kūpono loa ia no ka hoʻohana ʻana ma ke ʻano he mea hoʻopiha no nā lole hoʻoilo a i ʻole he lole no ka ski, ka piʻi mauna, a me nā lole ʻē aʻe.
(2) Ikaika kiʻekiʻe, elasticity maikaʻi, pale ʻaʻahu, a me ke kūpaʻa i ka palaho
He ikaika kiʻekiʻe ko ka Polypropylene (like i nā kūlana maloʻo a pulu) a he mea kūpono ia no ka hana ʻana i nā ʻupena lawaiʻa a me nā kaula; ʻOi aku ka maikaʻi o ke kūpaʻa a me ke kūpaʻa, like ka ikaika me ka polyester a me ka nylon, me ka helu rebound e like me ka nylon a me ka hulu hipa, ʻoi aku ka kiʻekiʻe ma mua o nā fibers polyester a me viscose; He paʻa haʻahaʻa ka polypropylene, he maʻalahi i ka pilling a me ka deformation, kū i nā microorganisms, a ʻaʻole ia e hōʻino; ʻOi aku ka maikaʻi o ke kūpaʻa kemika ma mua o nā fibers maʻamau.
(3) Loaʻa iā ia nā waiwai pale uila a me ka mālama ʻana i ka mehana
He kiʻekiʻe ke kū'ē uila o ka olonā polypropylene (7 × 10 Ω. cm) a he haʻahaʻa ka conductivity thermal. Ke hoʻohālikelike ʻia me nā olonā kemika ʻē aʻe, ʻoi aku ka maikaʻi o ka insulation uila a me ka paʻa ʻana o ka mehana o ka olonā polypropylene, akā he maʻalahi ia e hoʻoulu i ka uila static i ka wā e hana ai.
(4) Hana maikaʻi ʻole i ka wela a me ke kūpaʻa ʻana i ka ʻelemakule
He haʻahaʻa ka pae heheʻe o nā olonā polypropylene (165-173 ℃) a he paʻa ʻole hoʻi i ka mālamalama a me ka wela. No laila, he haʻahaʻa ka pale ʻana o nā olonā polypropylene i ka wela, ke kūpaʻa ʻana i ka ʻelemakule, a ʻaʻole kūpaʻa i ka hao ʻana. Eia nō naʻe, hiki ke hoʻomaikaʻi ʻia ka waiwai anti-kahiko ma ka hoʻohui ʻana i kahi mea anti-kahiko i ka wā e milo ai.
(5) Nā waiwai omo wai a me ka hoʻoluʻu maikaʻi ʻole
ʻO nā waiwai omo wai a me ka hoʻoluʻu ʻana o nā olonā polypropylene ka mea ʻino loa i waena o nā olonā kemika, me ka aneane ʻole omo wai a me ka helu hoʻihoʻi wai ma lalo o 0.03%. Loaʻa i ka polypropylene denier maikaʻi ka hopena omo kumu ikaika, a hiki ke hoʻopau ʻia ka mahu wai ma o nā capillaries i loko o nā olonā. Ma hope o ka hana ʻia ʻana i lole, ʻoi aku ka maikaʻi o ka ʻoluʻolu o ke kapa, ʻoi aku hoʻi me nā olonā polypropylene ultra-fine. Ma muli o ka hoʻonui ʻia o ka ʻili, hiki ke hoʻoili wikiwiki ʻia ka hou, e mālama ana i ka ʻoluʻolu o ka ʻili. Ma muli o ka omo ʻole o ka wai a me ka helu emi haʻahaʻa o nā olonā, loaʻa i nā lole polypropylene nā ʻano o ka holoi maʻalahi a me ka maloʻo wikiwiki.
ʻAʻole maikaʻi nā ʻano hoʻoluʻu o ka Polypropylene, nā waihoʻoluʻu māmā, a ʻaʻole paʻa ka hoʻoluʻu ʻana. ʻAʻole hiki i nā wahie maʻamau ke hoʻoluʻu iā ia, a ʻo ka hapa nui o nā olonā polypropylene kala e hana ʻia e ka hoʻoluʻu mua ʻana. Hiki ke hoʻohana ʻia ka hoʻoluʻu ʻana i nā mea maka a me ka hoʻololi ʻana i ka fiber, a hiki ke hoʻohuihui ʻia nā mea hoʻohuihui wahie ma mua o ka wili hoʻoheheʻe ʻia.
