Ke kiʻekiʻe hakakino polyethylene: hōʻuluʻulu manaʻo, 'ano, laulā

O ka lā, i loko o ka poepoe o kanaka aayoaeuiinoe hoʻolauna iā 'hou i nā mea i loaa mai ma kaʻimi hoʻopunipuni' ana. Kekahi o kēia mau mea he kiʻekiʻe hakakino kaumaha polyethylene, i mea mua a me ka 50-ies o ka hope kenekulia ua lilo ke kalepa huahana, akā, ka mea, ua ho onui maoli hiʻona a hiki i kēia manawa.

hōʻikeʻano

Ke kiʻekiʻe hakakino kaumaha polyethylene o kekahi o ka laha 'ana o ka thermoplastic polymerized'etolina. Kona papa kuhikuhiE hiʻona - he lōʻihi loa hakakino na kaula. Ka mea, i na mea maikai hoomaopopo, a ke hoʻouna i ka haawe, "offsetting" kā lākou intermolecular hana kūleʻa.

Kā lākou mau helehelena mea hoi i kekahi mau mai nāʻano o nā lula ea. Ua loaʻa i nā dudima, ai, ka mea, aole e liloʻawahia waiwai. He hiki iaʻu ke hana i kekahi waihoʻoluʻu manaʻo callers. I ka Ia manawa ia i ka lākou o ka waiwai i maopopo ia mea eʻoi aʻe ma luna o nā polymers.

Ke kiʻekiʻe hakakino kaumaha polyethylene mea he paakiki mea me ka kiʻekiʻe hopena ikaika. He mea hiki ke hoole aku i ke nui lua anakahi uila. Ua 'Aʻole i ka hoʻokemu ona mau, no ka mea, o ka mea ka mea, aole ia pāʻani ole me kanaka ili a me ia mea i pahee. Eia hou, ka mea, i ke kiʻekiʻe abrasion ia'ku (oi ma mua o kila) a me ka haahaa kaʻi lau waiwai o ke kū'ē.

ʻO ka waiwai o ka kiʻekiʻe hakakino ke kaupaonaʻana polyethylene

I ua kaulana, ka nui hiʻona o ke kiʻekiʻe pīlali hakakino na kaula i lōʻihi. No hoi, ka mea e aʻo i kaʻoihana i loko o ka e like me mamua. Kuni ihola ia i kūpono kou ia laua i kekahi i kekahi. Kēia wehewehe i ka ikaika o ka mea.

I loko nō o ka mea i ka mea kiʻekiʻe hakakino kaumaha polyethylene ano lōʻihi nā kaula hao, i ka pilina ma waena o ke kanaka nā lātoma, ua nawaliwali ia. Kēia huahelu mea haʻahaʻa ma mua ia o ka Kevlar ma ka liʻiliʻi mau nō mea. Kēia hiʻona i ka pīlali ua e hoʻa'ā i hoʻopale - ia heheʻe i ka wela o ka 144 kekelē Kelekia.

Ma keia polyethylene haku mele 'ana noi nā mea kemika, amines a hydroxyl pūʻulu, a e nā pono hana susceptible i chemicallyʻeleu a me ka loa hana kūpono. No ka mea, o keia waiwai mea e malama i ka wai, ona mau,ʻano pākīkē konohiki, microorganisms a me ultraviolet kukuna.

I ka papa kuhikuhiE ano o ka aaioee

Nā Koina e pono e i kiʻekiʻe-hakakino polyethylene, GOST 16338-85 be. E like me ia ia lakou, i ka hoʻololi kemikala o ka mea e alakai i ka aoao o ke metallocene catalysts i loko o ka lātoma -'etolina. No ka mea? Iecaianoaaiiie o huahana pololei a hiki i ka hope o ka papa kuhikuhiEʻano o ka lapaʻau i hoʻohana:

1. Ka tuko pīlali-spinning. e hui maka mea me ka'ūheheʻe. Ke kūpono nuipa a ua ikaika loa o Paulo ma i ka weheʻana i loko o ka wai. Hoʻonaʻauaoʻia filament puhi i ka umu i i ka wā hoʻokahi huki, a wehe i ka'ūheheʻe.
2. Hot koiʻana iā a sintering. Ka pauka nuipa ua'opihia nui ikaika, ma ia loaa homogeneous mea. Alaila, ia mea wela-ino - sintering i ka wela o 150-200 degere.
3. Rama extrusion. Ka maka mea ua hoʻoheheʻeʻia i ka homogeneous laholio-me nuipa a laila extruded ma kūikawā nozzles.

Loa kaiāulu tuko pīlali-spinning. No, ma keia ala loaa kiʻekiʻe hakakino kaumaha polyethylene olona, ua kiʻekiʻe ikaika.

E hoʻohana i nā luna hoʻolale hana

Na olona, hoʻohana no ka? Iecaianoaaiiie o kiʻekiʻe hakakino kaumaha pīlali i ua hoʻomano hoʻohana no ka hanaia'na o ke kino aiiay pono, i loko o ua kino kapa kila. Mahalo i kēia mau waiwai filaments like me ka haʻahaʻa kekahi kaumaha a me ka kiʻekiʻe'ē aʻe hua stress (ka lākiō o kēia mau indices mea 7-8 manawa oi aku ma mua ia o ka kila) kapa kila loaa ka malamalama, a me ka hoʻopale i ka pōkā, shrapnel a me kaʻino wale i kumu 'ē aʻe.

Kino kapa kila i ka a lahilahi loaa mai ma ka blending na olona, i kekahi i kekahi i kekahi pana pua. Mahalo i ka 'enehana a ua ikeia multiaxial lole - he kūikawāʻano o glassy Pūnaewele Puni Honua i hoomanawanui aʻo nui i loko o kekahi ao ao. Hoʻohana 'ia e mālama i ke kumu a me kaʻaoʻao kiʻekiʻe hakakino kaumaha polyethylene. Waiwai multiaxial lole hiki ke hoomalu a me ka mea e kahiko ai kaa, e like me ka hoʻohana 'ana o ka puluniu, e ho okumu i ka oki hoʻopale Loan.

Hoʻohana 'ia ma ka lapaau

I ka lapaau, kiʻekiʻe hakakino kaumaha polyethylene ua hoʻohanaʻano nui no ka hanaia'na o implants no ke ki kala a me ka spine o ke kuli. No ka mea manawa mua ia i ua hoʻohana me ia i ka manaʻo i loko o ka mamao 1962. A mai laila au i hoomaka ai e Kīwala'ō.

Hoʻomano hoʻohana a Hoʻololi 'mea - reticulated paha keʻa-ua hoʻopili pīlali. Ua Ua loaa ma ke kiʻekiʻe hakakino ke kaupaonaʻana polyethylene olona, obstrelivaniya gamma kukuna a me electrons, i mea crosslinked i kekahi i kekahi huakaʻi. Mahope, ka mea, hoi na hoopai ana a hiki i thermal ole, a ho'ēmi i kā kona'okesaside-ka ho'ēmiʻana hiki.

Olona, ka nānā 'ana ma luna o kēia mau maka i nā mea i hoʻohana no ka suturing. Alakaʻi ma ka hana ana i kēia mau huahana o ka poe DSM, i pau ai i ke kālepa ma kahi kuai no ka 'inikua sutures kapa Dyneema maemae.

E hoʻohana i ka hana

Ka loa hoʻomano hoʻohana ma o ka hana ua loaʻa ke kiʻekiʻe hakakino polyethylene pepa, a ua lako pū ai i ka? Iecaianoaaiiie market slab mānoanoa o ka 2 knm, Ma ke kumu o ua hanaʻia ea window 'ihiʻihi papa, PVC-panel hoʻonohonohoʻia a me kiʻekiʻe PVC profiles.

Ma mechanical e 'enekinia, no ka mea? Iecaianoaaiiie o hoailona iho la i apo, nā mea pilihao, hanaia'na o nā māhele, e hana ana i loko o ka neaa aila paha meakino, a ma pneumatic nenoai me kiʻekiʻe pae'ōnaehana puʻe, ka hapanui mau hoʻohana kiʻekiʻe-hakakino polyethylene 1000 - kekahi o na kumu nui pīlali? Ueo.
