nā huahana

I nā makahiki i hala iho nei, ua lilo ka māmā, ka haʻahaʻa kalapona, a me ka hana kiʻekiʻe i mau kumuhana nui ʻekolu o ka ʻoihana hana. ʻOiai he ikaika kiʻekiʻe nā mea metala kuʻuna, he kiʻekiʻe ko lākou density, hoʻohana nui i ka ikehu hana, a he maʻalahi hoʻi i ka pala; ʻOiai he hopena hōʻemi kaumaha koʻikoʻi nā plastics i hoʻoikaika ʻia i ke aniani pōkole maʻamau, hana maikaʻi ʻole lākou ma lalo o nā koi e like me ka hiki ke lawe i ka ukana lōʻihi, ke hoʻololi ʻana i nā mahana kiʻekiʻe a me ka haʻahaʻa, a me ka paʻakikī kiʻekiʻe o ka paia lahilahi.

Ma kēia ʻano, ʻo ka polypropylene i hoʻoikaika ʻia me ke aniani lōʻihi (LGF-PP) a me ka polyamide i hoʻoikaika ʻia me ke aniani lōʻihi (LGF-PA66) kekahi o nā māhele ulu wikiwiki loa ma ke kahua plastics i hoʻololi ʻia ma ka honua. Wahi a nā helu helu ʻoihana, manaʻo ʻia ka nui o ka mākeke honua o nā composites thermoplastic i hoʻoikaika ʻia me ke aniani lōʻihi e ulu mai kahi o 2.8 biliona kālā US ma 2023 a i 4.5 biliona kālā US ma 2030, me ka nui o ka ulu makahiki hui makahiki ma kahi o 7.2%, i hoʻokele nui ʻia e nā lula māmā a me nā kaomi kumukūʻai.

一、Nā pono loea koʻikoʻi o nā mea i hoʻoikaika ʻia i ka fiber aniani lōʻihi

ʻAʻole e like me nā plastics i hoʻoikaika ʻia i ke aniani pōkole (maʻamau he 0.2-0.6mm ka lōʻihi), mālama nā mea i hoʻoikaika ʻia i ke aniani lōʻihi i ka lōʻihi o ke aniani o 10-25mm i loko o ka matrix resin ma o nā kaʻina hana impregnation a me extrusion kūikawā, a hana i kahi ʻano pūnaewele ʻekolu-dimensional ma hope o ka hoʻoheheʻe ʻana i ka injection. Pono e hoʻomaopopo ʻia ʻo ke kiʻekiʻe o ka paʻa ʻana o kēia ʻano pūnaewele e pili ana i ka hoʻolālā wili a me ke ʻano o ka puka i ka wā o ka hoʻoheheʻe ʻana i ka injection; Inā kūpono ʻole ke kaʻina hana, hiki ke emi nui ka lōʻihi o ka fiberglass.

Lawe mai kēia ʻano hana i ʻekolu mau hoʻomaikaʻi hana koʻikoʻi:

1. Ke kūpaʻa hopena kiʻekiʻe loa

Hiki i ka pūnaewele olonā aniani lōʻihi ke pale pono i ka laha ʻana o ka māwae, a ʻo kona ikaika hopena notch he 40% -80% kiʻekiʻe ma mua o ka fiber pōkole PP/PA. Ma ka mahana haʻahaʻa o -40 ℃, hiki i nā mea maʻamau ke haki palupalu, ʻoiai hiki i nā mea olonā aniani lōʻihi ke mālama i ka hana hopena ma mua o 80% ma ka mahana o ka lumi. Hoʻokumu ʻia ka ʻikepili ma luna ma nā kūlana hoʻāʻo ISO 179 a i ʻole ASTM D256.

2. Kū'ē kolo maika'i loa a me ke kūpa'a o ka dimensional

Ma lalo o nā ukana paʻa lōʻihi (e like me nā mōlina kaʻa a me nā wāwae kākoʻo mīkini home), e loli nui ka ʻano o nā mea fiber pōkole, ʻoiai e emi ana ka nui o ka loli o nā mea fiber aniani lōʻihi ma mua o 50% ma muli o ke kākoʻo ʻana o ke kinoea fiber aniani. I kēia manawa, i nā hoʻāʻo kaʻapuni wela kiʻekiʻe a me ka haʻahaʻa mai -40 ℃ a i 120 ℃, ʻo ka hoʻololi ʻana o nā huahana fiber aniani lōʻihi he hapakolu wale nō ia o nā fiber pōkole. ʻO kēia ka mea e kūpono ai nā mea LGF no nā ʻāpana me nā loli nui o ka mahana o waho.

3. ʻO ka lokahi o ka ikaika kiʻekiʻe a me ka māmā

ʻO ka nui o ka paʻa he 1/2-1/3 wale nō o ka aluminika hui (ʻo LGF-PP ma kahi o 1.0-1.2 g/cm³, ʻo LGF-PA66 ma kahi o 1.3-1.5 g/cm³), akā ʻo ka ikaika kikoʻī (ikaika/nui) kokoke a ʻoi aku paha i kekahi mau aluminika hui, e lilo ia i koho kūpono no ka hoʻokō ʻana i ka "pani ʻana i ke kila me ka plastic". No ka laʻana, hiki i ka ikaika tensile o LGF-PP40 ke hiki i 120-150 MPa, a hiki i ka modulus bending ke hiki i 10-12 GPa, kahi i lawa ai e pani i nā metala no ka hapa nui o nā ʻāpana semi-structured.

二、Nā wahi noi maʻamau a me nā koi kikoʻī no nā mea hana ma kēlā me kēia kahua

Nā laʻana o nā ʻāpana ʻoihana, nā koi koʻikoʻi, nā mea i ʻōlelo ʻia

三ʻIkepili o ke au o ka mākeke

Wahi a nā helu helu ʻaoʻao ʻekolu, ʻo ka nui o ka mākeke honua o nā composites thermoplastic i hoʻoikaika ʻia me ke aniani lōʻihi e manaʻo ʻia e hiki i kahi o 2.8 biliona kālā US ma 2023, a ua manaʻo ʻia e hiki i ka 4.5 biliona kālā US ma 2030, me ka nui o ka ulu ʻana o ka hui makahiki he 7.2%. Punaewele ʻikepili: Nā hōʻike ʻoihana e like me MarketsandMarkets. I waena o lākou, ʻo ka ʻāina ʻo Asia Pacific ka wikiwiki o ka ulu ʻana, a ʻo Kina, ma ke ʻano he mea hana nui a me ka mea hoʻopuka aku i nā plastics i hoʻololi ʻia, ke pani mālie nei i nā mea maka ʻEulopa a me ʻAmelika pipiʻi. ʻO ka mana hoʻokele koʻikoʻi ka pono o ke kumukūʻai (20% -30% haʻahaʻa ma mua o nā hōʻailona ʻEulopa a me ʻAmelika) a me nā pōʻaiapuni hoʻouna pōkole.

四ʻO kā mākou kūlana

Ua kālele kā mākou hui i ka noiʻi a me ka hana ʻana o LGF-PP a me LGF-PA66 no nā makahiki he 20 a ʻoi, a he ʻōnaehana hana kūʻokoʻa no ka ʻenehana hoʻopili ʻana i ka fiber aniani lōʻihi. Ua hoʻokuʻu nui ʻia ka huahana i ʻEulopa, Rusia, Hikina Hema ʻAsia, Hikina Waena, ʻAmelika Hema a me nā wahi ʻē aʻe.

ʻAʻole mākou e koi aku ʻo mākou wale nō a ʻoi aku ka maikaʻi, akā hāʻawi mākou i nā koho ʻē aʻe i hōʻoia ʻia. Ke hoʻohālikelike ʻia me nā lama ʻEulopa a me ʻAmelika nui e like me SABIC, Celanese, a me DSM, ʻo kā mākou pono kumukūʻai maʻamau he 20% -25%, ʻoiai e mālama ana i 85% -95% o kāna hana mīkini, kahi i hōʻoia ʻia ma o ka hoʻāʻo ʻana o ka batch e nā mea kūʻai aku he nui.

ʻAʻole mākou e hāʻawi wale i nā māka maʻamau, akā hoʻopilikino pū mākou i nā ʻano hana e like me nā wahi hoʻohana a nā mea kūʻai aku (nā mahana kiʻekiʻe a haʻahaʻa, ka makū, nā ʻila aila, ka ʻike ʻana i waho), e kōkua ana i nā mea kūʻai aku e hōʻemi nui i nā kumukūʻai mea me ka hōʻoia ʻana i ka hana.He ʻike kūpono: ʻO ka maʻamau, pono nā ʻano hana i hana ʻia i 4-6 mau pule o ka hoʻoponopono ʻana i ke ʻano hana a me ka hōʻoia ʻana o ka laʻana ma mua o ke komo ʻana i ka hana nui ʻana.
