ʻO ka Polyester vs. Nylon Flat Slings: Ke Kūʻai Kemika a me ka Elongation Profiles

Pono ka mea kanu kemika i ka maʻa palahalaha no ka hāpai ʻana i nā ʻāpana kila kuhiliʻole i loko o kahi kaiapuni kahi e loaʻa ai ka uahu waika. Pono kahi hale hoʻoponopono kai i ka maʻa e hiki ke mālama i ka ʻaila hydraulic a me ka ʻike wai kai. Pono nā hana ʻelua i nā maʻa palahalaha synthetic-akā ʻokoʻa ke koho waiwai kūpono no kēlā me kēia.

Lishenflex i ka synthetic Ua hana ʻo nā maʻa palahalaha no ʻelua mau makahiki ʻoi aku, a ʻo kekahi nīnau a mākou e lohe pinepine ai ʻo ia: Polyester a i ʻole nylon — ʻo wai ka mea maikaʻi loa? ʻAʻole maʻalahi ka pane. Wahi a Wikipedia i komo ai ma ka polyester , polyester kahi ʻāpana o nā polymers i waiwai ʻia no kona kūpaʻa, kūpaʻa kemika, a me ka haʻahaʻa haʻahaʻa. Wikipedia ma ka nylon ʻO ke komo ʻana o e wehewehe ana i ka waiwai o ka nylon no kona ikaika, elasticity, a me ka pale ʻana i ka abrasion. Hana nā mea ʻelua i nā maʻa hāpai maikaʻi, akā ʻaʻole hiki ke hoʻololi ʻia . Wahi a ka Canadian Center for Occupational Health and Safety (CCOHS) , ua hoʻopōʻino ʻia nā maʻa nylon e nā waikawa akā pale i ka alkalis, ʻoiai ʻo nā maʻa polyester e hōʻino ʻia e ka alkali akā kūʻē i nā waikawa. ʻO ke kī ʻo ka hoʻohālikelike ʻana i nā mea me ke kaiapuni.

Palekana Kemika: ʻO ka ʻokoʻa palekana palekana

ʻO ka ʻokoʻa koʻikoʻi ma waena o ka polyester a me ka nylon flat slings ʻo kā lākou hoʻohālikelike kemika . ʻO ke koho ʻana i ka mea hewa no kahi kaiapuni kemika hiki ke alakaʻi i ka pōʻino pōʻino - pinepine me ka ʻike ʻole ʻia.

Wahi a ke alakaʻi hoʻohālikelike waiwai a Liftex, , ʻo nā ʻokoʻa kūʻē kemika nui :

Puna: Liftex; CCOHS; CERTEX Denemaka

Hōʻoia ʻo CCOHS i ka hoʻohaʻahaʻa ʻana o ka nylon i nā ʻakika mai ka ʻole a hiki i ka hōʻemi ʻana, ʻoiai ʻo ka polyester ke kūpaʻa i nā ʻakika he nui akā ua pōʻino ʻia e ka alkali. Hoʻohui ʻo CERTEX Denmark e hiki ke hoʻopili ʻia nā hopena o nā ʻakika a i ʻole nā ​​​​alkali i nā haʻahaʻa haʻahaʻa ma o ka hoʻoheheʻe ʻana a me ka pōʻino.

ʻŌlelo aʻo palekana koʻikoʻi : ʻAʻole pinepine ʻia nā pōʻino kemika i nā maʻa synthetic ʻike . Hoʻonāwaliwali nā kaula i loko a ʻike ʻia ka maʻa ma ka ʻili. Wahi a Empire Rigging , ʻaʻole ʻike pinepine ʻia ka pōʻino kemika-e nāwaliwali nā fibers i loko a ʻoiai ke ʻano maʻamau o ka maʻa ma waho, ʻo ia ke kumu e pono ai ka ʻike i kou kaiapuni ma mua o kou koho ʻana i kāu mea.

Nā Kaiapuni ʻAka—E koho i ka Polyester

Ke hāpai ʻia i loko o nā kaiapuni me ka ʻike ʻana i ka waika—mea kanu kemika, hana pākaukau, hoʻopau metala, wili pepa— ʻo ka polyester ke koho pololei. ʻO ka nylon, ma ka ʻokoʻa, ua luku ʻia e nā waikawa. Hoʻomaopopo ʻo Mazzella Companies i ka hoʻohaʻahaʻa ʻana o ka nylon i nā ʻakika mai ka liʻiliʻi a hiki i ka pau ʻana, ʻoiai ʻo ka polyester ke kūpaʻa i ka nui o nā waikawa. Hoʻomaopopo ka NSRP Ship Production Rigging Guide e hiki i ka hydrochloric a me ka sulfuric acids, ʻoiai ma ke ʻano i hoʻoheheʻe ʻia, hiki ke hoʻemi nui i ka ikaika ma ka nylon.

Nā Kaiapuni Alkali—E koho i ka Nylon

Ke hāpai ʻia i loko o nā kaiapuni me ka ʻike alkali — nā hoʻomaʻemaʻe hoʻomaʻemaʻe caustic, ka hana ʻana i ka palaki, kekahi hana kemika - ʻo nylon ka koho maikaʻi loa. Hoʻopilikia ʻia ka polyester e ka alkalis, ʻoiai ʻaʻole pale ʻia ka nylon i ka hopena o ka alkalis. Hoʻomaopopo ke alakaʻi waiwai fiber UNIROPE he kūʻē maikaʻi ka nylon i nā aldehydes, hydrocarbons, ethers, a me kekahi mau alkali.

Nā Koho Elongation: Hoʻopololei ma lalo o ka ukana

ʻO ka ʻokoʻa nui ʻelua ma waena o nā maʻa palahalaha polyester a me ka nylon he elongation - pehea ka nui o ka maʻa i ka wā e hoʻouka ai.

Hāʻawi ʻo Liftex i ka ʻikepili elongation penei:

Puna: Liftex; UNIROPE

Polyester—Pono a me ka Pa'a

ʻO ka lōʻihi haʻahaʻa o ka Polyester (3-4% ma ka haʻahaʻa helu) ʻo ia ka mea i koho ʻia no:

• Ke hoʻonohonoho pono ʻana i ka ukana - ʻo ka liʻiliʻi liʻiliʻi ʻo ia ka mana maikaʻi

• Nā noi lumi poʻo haʻahaʻa — ʻoi aku ka liʻiliʻi o ka wahi kū i ka wā hāpai

• Nā haawe hiki ʻole ke ʻae i ke kuʻi ʻana a i ʻole ke koli ʻana

• Pono nā hana e hoʻokiʻekiʻe paʻa, wānana

Hāʻawi ʻo Empire Rigging i kahi laʻana kūpono: ʻo ka hāpai ʻana i kahi ukana 20-kapuaʻi me kahi maʻa nylon e hoʻolōʻihi i 10% ka hopena i ʻelua mau kapuaʻi o ka elongation, ʻoiai ʻo ka maʻa polyester e kau wale ma kahi o ʻehiku ʻīniha wale nō. Ma nā wahi ākea paʻa, pono kēlā ʻokoʻa.

ʻO Nylon—Hoʻopuʻi ʻia a me ka 'kala kala'

ʻO ka lōʻihi kiʻekiʻe o ka Nylon (6-10% ma ka ukana helu) hāʻawi:

• ʻO ka haʻalulu —ʻo ka mea 'hāʻawi' ma mua o ka lawe ʻana i ka ikaika

• ʻOi aku ka maikaʻi o ka hoʻouka ʻana i nā ukana i ka wā hāpai

• ʻO ke kala ʻana ma luna o nā lako hana maʻamau - ʻoi aku ka kala ʻana o ka nylon inā e hoʻopili ʻia a hoʻokomo ʻia ma luna o nā ʻano hāmeʻa like ʻole.

• ʻO ka palena palekana o ka mea hoʻohana i hoʻonui ʻia - e hoʻopaʻa i nā ukana hikiwawe

Wahi a Liftex , ʻo ke kiko kiʻekiʻe o ka nylon ka mea e hoʻopaneʻe ai i ka haʻalulu, e hoʻolilo iā ia i ke koho i makemake ʻia i ka wā e neʻe ai nā ukana a i ka wā e hopohopo ai ka hoʻouka ʻana.

ʻO ka wai a me ka pane UV

Nā hopena wai

He hygroscopic ka Nylon — hoʻomohu ia i ka makū mai ke kaiapuni. Wahi a ka NSRP Ship Production Rigging Guide , nalo ka nylon i ka 15% o kona ikaika ke hoʻopaʻa . ʻo Liftex a me CCOHS i kēia, me ka ʻike ʻana e hiki i nā maʻa nylon ke lilo i 10-15% ka mana ke pulu. Hoʻihoʻi hou ʻia ka ikaika ma ka maloʻo ʻana, akā ʻaʻole pono e hoʻohana ʻia ka maʻa ma ke ʻano i koho ʻia ke pulu.

ʻAʻole komo ka Polyester i ka wai a ʻaʻohe nalowale ikaika i ka wā pulu. ʻO kēia ka polyester i koho maikaʻi ʻia no:

• Nā noi moana a me waho

• ʻO nā hāpai waho ma nā kūlana pulu

• Nā kaiapuni me ka haʻahaʻa kiʻekiʻe

Hoʻomaopopo ʻo CERTEX Denmark ʻaʻole komo ʻo Dyneema® i ka wai, ʻaʻole like me nā mea ʻē aʻe e like me ka polyester a me ka polyamide.

Ke kū'ē UV

ka Polyester i Hāʻawi ka pale UV maikaʻi i hoʻohālikelike ʻia me ka nylon. Hoʻopilikia ʻia nā fila nylon e nā kukuna UV a me ka lā, e hopena i ka nalowale o ka ikaika i ka manawa. Hoʻomaopopo nā ʻoihana ʻo Mazzella ʻo nā kaiapuni kahi e hōʻike mau ʻia ai nā maʻa pūnaewele synthetic i ke kukui ultra-violet hiki ke hoʻopilikia i ka ikaika o ka webbing synthetic i nā pae like ʻole, mai ka liʻiliʻi a hiki i ka hoʻohaʻahaʻa holoʻokoʻa, a ʻo ka hoʻohaʻahaʻa ʻana he kumulative. No nā maʻa i hoʻohana ʻia i waho a i ʻole i ka lā pololei, ʻo ka polyester ka koho lōʻihi loa.

Palena Mahana

Ma lalo o EN 1492-1 , kūpono nā maʻa polyester a me ka nylon no ka hoʻohana ʻana a me ka mālama ʻana i ka pae wela -40°C a 100°C . Pili kēia i nā mea ʻelua. Eia naʻe, ʻike ʻo Empire Rigging i kahi ʻokoʻa kūpono i nā palena hoʻohana mau: ua helu ʻia ka nylon a hiki i 194°F (90°C), ʻoiai ua helu ʻia ka polyester a hiki i 180°F (82°C)—haʻahaʻa iki. Ma luna o kēia mau mahana, hoʻomaka nā mea e nalowale i ka ikaika.

Manaʻo koʻikoʻi : I loko o kahi kaiapuni kemika, ʻokoʻa paha kēia mau pae wela, a pono e ʻimi ʻia ka ʻōlelo aʻo a ka mea hoʻolako.

ʻIke: Pehea e haʻi ai i ka polyester mai ka Nylon

Pono ʻo ASME B30.9 a me WSDA-WS-1 e loaʻa i kēlā me kēia maʻa pūnaewele kahi hōʻailona paʻa e hōʻike ana i ka mea. Eia kekahi, ʻo nā maʻa polyester he laina ʻike polū i ulana ʻia i loko o ka webbing —inā ʻike ʻoe i ka laina polū, he polyester. ʻAʻole kēia laina ʻike i nā maʻa nylon. Hoʻopili like ka ʻōnaehana kala kala ma lalo o EN 1492-1 i nā mea ʻelua.

Alakai Koho

Hōʻuluʻulu a me nā Manaʻo Hoʻomaʻamaʻa

Hāʻawi ka polyester a me ka nylon flat slings i ka ikaika maikaʻi a me ka lōʻihi, akā ʻaʻole hiki ke loli . ʻO ke koho ʻana i ka mea hewa no kou kaiapuni hiki ke alakaʻi i ka hōʻino huna a me ka hāʻule koke.

Nā mea nui e lawe ai:

1. Kaiapuni ʻakika = Polyester — hoʻopau ʻia ka nylon e nā ʻakika

2. Kaiapuni alkali = Nylon —ua poino ka polyester e ka alkali

3. ʻO nā hoʻokiʻekiʻe pololei = Polyester —ʻo ka elongation haʻahaʻa e hāʻawi i ka mana

4. ʻO nā haʻahaʻa ikaika = Nylon — ʻoi aku ke kiʻekiʻe o ka hoʻopaʻa ʻana i nā haʻalulu

5. Ma waho / pulu = Polyester —UV-pale a me ka makū

6. E nānā i ka laina polū — ʻo nā maʻa polyester he laina tracer polū; ʻAʻole naylon

7. E hōʻoia mau i ka hōʻailona —ASME B30.9 pono ka ʻike mea ma ka maʻa maʻa

Hana ʻo Lishenflex i nā maʻa paʻa polyester a me ka nylon i nā kūlana EN 1492-1 a me ASME B30.9, me ka ʻike pono mea a me nā hōʻailona hiki ke hoʻopaʻa ʻia. Hāʻawi mākou i ke alakaʻi no ke koho ʻana i nā mea e pili ana i kāu kaiapuni kemika kikoʻī a me nā koi noi.

Inā makemake ʻoe i ke kōkua no ka hoʻoholo ʻana inā ʻo ka polyester a i ʻole ka nylon ka koho kūpono no kāu hana hāpai ʻana—a i ʻole makemake i kōkua e ʻike i ka maʻa kūpono no kahi kaiaola hana kemika—e ʻoluʻolu e hoʻouna i leka uila i sales@lishenflex.com , a e hāʻawi kā mākou hui loea i ke kākoʻo hoʻokahi.
