Ka hoʻomaopopo ʻana i ka ikaika haʻihaʻi a me ka elongation ma ke kaula poliester PET

ʻO nā helu ʻelua e wehewehe i ka hana

I ka loiloi ʻana ʻO ke kaula PET (polyester strap), ʻelua mau waiwai mechanical ʻoi aku ka nui ma mua o nā mea ʻē aʻe: ka haki ʻana i ka ikaika a me ka elongation. Hoʻoholo pū lākou inā e hoʻopaʻa ke kaula i kāu ukana, e hoʻomau i ka haʻalulu i ka wā e hele ai, a e hana pono i kāu mau mea hana. Wahi a ASTM D3950, ʻo ke kikoʻī maʻamau no ka strapping, pono e hoʻāʻo a hōʻoia ʻia ka ikaika haʻihaʻi a me ka elongation no kēlā me kēia pūʻulu hana.

Ma Jushuo Packaging , hōʻike kā mākou ʻikepili hana i nā mea kūʻai i hoʻomaopopo i kēia mau waiwai ʻelua e hana i nā hoʻoholo kikoʻī maikaʻi aʻe. Hōʻike kēia alakaʻi i ke ʻano o ka haki ʻana i ka ikaika a me ka elongation, pehea lākou e launa pū ai, a pehea e hoʻohana ai iā lākou no ke koho ʻana i ke kaula PET kūpono.

1. Ka Haʻihaʻi ʻana i ka ikaika: ʻO ka Metric Kapaa Load

1.1 He aha ka mea e haki ai ka ikaika?

ʻO ka ikaika haʻihaʻi (i kapa ʻia hoʻi ka ikaika haʻihaʻi a i ʻole ka ikaika tensile) ʻo ia ka ikaika kiʻekiʻe loa e hiki i ke kaula ke kū ma mua o ka haki ʻana. Wahi a ASTM D3950, ana ʻia ka ikaika haʻihaʻi ma ka huki ʻana i kahi laʻana o ke kaula a hiki i ka pau ʻana, e hoʻopaʻa ana i ka ikaika kiʻekiʻe loa.

Hōʻike pinepine ʻia ka ikaika haʻihaʻi ma:

• Kilograms (kg) : Mea maʻamau i nā mākeke ʻEulopa a me ʻAsia

• Paona (lbs) : Maʻa mau ma nā mākeke ʻAmelika ʻĀkau

• Nā Newtons (N) : Kūlana ʻepekema

• Megapascals (MPa) : Waiwai waiwai (ikaika no kēlā me kēia ʻāpana)

1.2 Kiʻekiʻe o ka haʻihaʻi maʻamau no ke kaula PET

Wahi a nā kikoʻī o ka ʻoihana, ʻo ke kaula ʻo PET e wāwahi ana i ka ikaika mai 160kg a 1,360kg ma muli o ka laulā, mānoanoa, a me ka papa:

1.3 Pehea e ho'āʻo ʻia ai ka ikaika haʻihaʻi

Wahi a ASTM D3950, ʻo ka hoʻāʻo ʻana i ka ikaika e hahai i kahi kaʻina hana maʻamau:

1. Hoʻomākaukau laʻana: Nā hōʻailona hōʻailona mai ka hui hana

2. Ka wikiwiki hoʻāʻo: Ka wikiwiki hoʻāʻo maʻamau (maʻamau 50mm/min)

3. Ana: Hoʻopaʻa ʻia ka ikaika kiʻekiʻe i ka wā hoʻomaha

4. Ka loiloi hopena: Pono e hoʻokō a ʻoi aku paha ma mua o ka ikaika haki

Loaʻa ka palapala hōʻoia o Jushuo Packaging i nā hopena hoʻāʻo ikaika no kēlā me kēia pūʻulu hana.

2. Elongation: The Stretch Behavior Metric

2.1 He aha ka Elongation?

ʻO ka elongation (i kapa ʻia hoʻi ka elongation ma ka haʻihaʻi) ʻo ia ka nui o ke kaula i hohola ʻia ma mua o ka haki ʻana, i hōʻike ʻia ma ke ʻano he pākēneka o kona lōʻihi kumu. Wahi a ASTM D3950, ana ʻia ka elongation i ka wā o ka hoʻāʻo tensile like e hoʻoholo ai i ka ikaika haki.

No ke kaula PET, ʻo ka hoʻolōʻihi ʻana i ka wā hoʻomaha maʻamau mai ka 10% a i ka 18% , ʻoi aku ka haʻahaʻa ma mua o ke kaula PP (12-20%) a ʻoi aku ka haʻahaʻa ma mua o ka nylon (30%+).

2.2 No ke aha he mea nui ka Elongation

Hoʻopili ka elongation i ke ʻano o ke kaula ma lalo o ka ukana:

2.3 Pehea e ho'āʻoʻia ai ka lōʻihi

Wahi a ASTM D3950, ana ʻia ka elongation i ka wā hoʻāʻo tensile:

1. Hoʻopaʻa ʻia ka lōʻihi mua

2. Kau ʻia ke kaula a haki

3. Hoʻopaʻa ʻia ka lōʻihi hope i ka wā hoʻomaha

4. Ua helu ʻia ka elongation e like me ka piʻi pākēneka

Ma Jushuo Packaging , hōʻoia kā mākou ʻikepili lab e hāʻawi mau ana ke kaula PET i nā waiwai elongation ma ka pae 10-18%, ma muli o ka pae a me ka mānoanoa.

3. Ka pilina ma waena o ka haki ʻana i ka ikaika a me ka lōʻihi

3.1 ʻO ke kālepa-off

ʻO ka ikaika haʻihaʻi a me ka elongation pili i nā ʻano ʻokoʻa. Wahi a nā loina ʻepekema waiwai, loaʻa pinepine kahi kālepa:

• ʻO ka ikaika haʻihaʻi kiʻekiʻe e hele pinepine mai me ka elongation haʻahaʻa

• ʻO ka elongation kiʻekiʻe pinepine ʻo ia ka ikaika haʻahaʻa haʻahaʻa

Aia kēia kālepa-off no ka mea molecular orientation —ka hoʻolikelike ʻana o nā kaulahao polymer e hoʻonui ai i ka ikaika—e hoʻemi ana hoʻi i ka hiki o nā mea ke kikoo.

3.2 No ke aha i loaʻa ai i ka PET ʻelua

Loaʻa i ke kaula PET kahi kaulike kūpono o ka ikaika haʻihaʻi kiʻekiʻe a me ka elongation haʻahaʻa ma o kāna kaʻina hana. Wahi a nā palapala patent e pili ana i ka hana strapping, ʻo ka hoʻomalu ʻana i ka lakene huki i ka wā hana e pili pono i nā waiwai ʻelua:

Hana ʻia ke kaula PET i nā lakene huki e hāʻawi i ka ikaika haʻihaʻi kiʻekiʻe me ka elongation haʻahaʻa-ʻo ka hui kūpono no ka palekana ukana.

4. Nā hoʻohana pono

4.1 Hoʻouka Palekana

Hoʻoholo ka ikaika haʻihaʻi i ka haʻawe kiʻekiʻe loa i hiki i ke kaula ke paʻa. E like me nā kūlana palekana, pono e helu ʻia ka strapping ma ka liʻiliʻi he 150% kiʻekiʻe ma mua o nā ukana hana i manaʻo ʻia e hoʻokō i nā haʻalulu haʻalulu a me ka hoʻohaʻahaʻa waiwai.

Ka helu laʻana:

• Kaumaha kaumaha: 500kg

• Pono ka ikaika haʻihaʻi: 500kg × 1.5 = 750kg ka liʻiliʻi

4.2 Paʻa Paʻa

Hoʻopili ka elongation i ka maikaʻi o ka mālama ʻana o ke kaula i ke ʻano o ka manawa. ʻO ke kaula PET elongation haʻahaʻa e hoʻomau i ka haʻalulu i ka wā e hoʻopaʻa ai nā ukana, ʻoiai e hoʻomaha paha nā kaula elongation kiʻekiʻe. No ka hoʻouna lōʻihi, makemake ʻia ka elongation haʻahaʻa.

4.3 Nā lako lako

Pili nā waiwai ʻelua i ka hana ʻana o nā mea hana. Wahi a nā mea hana mea hana, ua calibrated nā mīkini strapping maʻalahi no ka ikaika haʻihaʻi a me nā pae elongation. ʻO ka hoʻohana ʻana i ke kaula ma waho o kēia mau pae hiki ke hoʻopilikia i ka hānai ʻana, ka pau ʻole o ka sila, a i ʻole nā ​​​​mea hana.

5. Nā Kūlana Koho

5.1 Hoʻohālikelike i nā waiwai me nā noi

5.2 Noʻonoʻo i nā kumu palekana

E like me nā kūlana palekana, e hoʻopili mau i kahi mea palekana:

• Nā haʻahaʻa paʻa : 1.5 × ka liʻiliʻi

• Nā haʻahaʻa ikaika : 2× liʻiliʻi

• Nā noi koʻikoʻi : 3 × manaʻo ʻia

5.3 Ho'āʻo Laʻana

E like me nā kūlana maikaʻi, ʻōlelo ʻia ka hoʻāʻo ʻana ma mua o ka hana piha. E ho'āʻo i ka ikaika haʻihaʻi a me ka elongation e hōʻoia i nā kikoʻī e hoʻokō i nā koi.

Hāʻawi ʻo Jushuo Packaging i nā laʻana me ka ikaika haki a me nā waiwai elongation no ka hōʻoia.

Hōʻuluʻulu manaʻo

ʻO ka ikaika haʻihaʻi a me ka elongation ʻelua mau mea koʻikoʻi koʻikoʻi o ke kaula PET . Hoʻoholo ka ikaika haʻihaʻi i ka haʻahaʻa kiʻekiʻe i hiki i ke kaula ke hoʻopaʻa ʻia, ʻoiai ʻo ka elongation e hoʻoholo i ke ʻano o ke kaula ma lalo o ka ukana. Hiki i ke kaula PET ke koena maikaʻi loa o ka ikaika haʻihaʻi kiʻekiʻe (160-1,360kg) a me ka elongation haʻahaʻa (10-18%) ma o nā kaʻina hana hoʻomalu.

Ke koho ʻana i ke kaula PET, e noʻonoʻo pū i nā waiwai ʻelua: ka haki ʻana i ka ikaika no ka hiki ke hoʻouka a me ka mea palekana, elongation no ka paʻa ʻana o ka ʻāʻī a me ke kūpono o ka noi. E noi i kahi kumu palekana 1.5x liʻiliʻi no nā haʻahaʻa static a me 2 × no nā haʻahaʻa ikaika. No ka hoʻouna lōʻihi a i ʻole nā ​​ukana paʻa, makemake ʻia ka elongation haʻahaʻa. No nā haawe compressible, hāʻawi ka elongation haʻahaʻa i ka haʻalulu haʻalulu.

Hāʻawi ʻo Jushuo Packaging i nā hāmeʻa kāʻei PET piha me ka ikaika haki a me nā kikoʻī elongation. ʻO kā mākou hiki ke hana - 4 mau laina hana PET me 20,000 tons makahiki - e hōʻoia i ka hana maʻamau ma nā ʻāpana āpau. Hāʻawi mākou i nā palapala hoʻāʻo piha me kēlā me kēia hoʻouna a kākoʻo i nā mea kūʻai aku ma o ke koho kikoʻī.

Inā makemake ʻoe i ke kōkua e hoʻomaopopo i ka haki ʻana i ka ikaika a me ka elongation no kāu noi kāʻei PET, e ʻoluʻolu e hoʻouna i leka uila i sales@jushuopackaging.com , a e hāʻawi kā mākou hui ʻoihana i ke kākoʻo hoʻokahi.
