Ka Mana Viscosity i ke kaula PET: No ke aha he 0.60–0.95 dl/g i mea nui no ka ikaika

ʻO ka helu huna ma hope o ka ikaika o ke kaula PET

Ke hōʻike mai nā mea kūʻai ʻO ke kaula PET (polyester strap), ke nānā pinepine nei lākou i nā ana i ʻike ʻia: ka laulā, ka mānoanoa, a me ka ikaika haki. Eia nō naʻe, ʻo ka hana mechanical o ke kaula i hoʻopau ʻia e kuhikuhi ʻia e kahi kikoʻī ʻike ʻole o ka mea maka: intrinsic viscosity (IV).

ʻO ka viscosity kahi ana o ke kaumaha molekala o ka resin polyester. Hoʻoholo ia i ka lōʻihi o nā kaulahao polymer a me ka ikaika o ka paʻa ʻana o kekahi i kekahi. I ka ʻoihana strapping, ʻo ka wahi momona no ke kaula PET kiʻekiʻe kiʻekiʻe he viscosity ākea o 0.60 a 0.95 dl / g..

Inā haʻahaʻa loa ka viscosity, pōkole nā ​​kaulahao polymer, ka hopena i ke kaula i nele i ka ikaika tensile a hiki ke haki. Inā kiʻekiʻe loa ka viscosity, ʻoʻoleʻa loa ka resin no ka hana pono ʻana, e alakaʻi ana i nā hemahema o ka hana ʻana.

Ma Jushuo Packaging, hōʻike kā mākou ʻikepili hana i ka mālama ʻana i ka mana viscosity koʻikoʻi ma waena o 0.60 a me 0.95 dl / g he mea nui ia no ka hana ʻana i ke kaula i hiki ke pani i ke kila i nā noi kaumaha.

1. He aha ka Intrinsic Viscosity?

1.1 Wehewehe a ana

ʻO ka viscosity intrinsic (IV) kahi ana o ka hiki i ka polymer ke kahe i loko o kahi haʻina, e hoʻopili pololei me kona kaumaha molekala. Wahi a nā loina ʻepekema polymer, ua ana maʻamau ka IV i nā deciliters no ka gram (dl/g). No ka PET resin i hoʻohana ʻia i ke kaulahao, hōʻike ke ana i ke ʻano o ka polymerization.

1.2 No ke aha e hāʻule ai ka Viscosity i ka wā o ka hana ʻana

I ka wā o ka extrusion, hoʻoheheʻe ʻia ka resin PET i nā wela kiʻekiʻe. Wahi a ka hana kemika, hiki i ka wela a me ka wai ke hoʻoulu i ka hydrolysis, wāwahi i nā kaulahao polymer a hoʻohaʻahaʻa i ka viscosity. Me ka ʻole o ka mana kūpono, ʻoi aku ka liʻiliʻi o ke kaula i hoʻopau ʻia ma mua o ka mea maka, e alakaʻi ana i nā waiwai mechanical.

2. ʻO ke kuleana o ka Viscosity i ka ikaika o ke kaula

2.1 Ka ikaika ʻo Tensile

Pili pono ka ikaika tensile i ke kaumaha molekala. ʻO nā kaulahao polymer lōʻihi (ʻoi aku ka viscosity) e hana i nā kiko entanglement hou aʻe, e kūʻē i ka haki ʻana ma lalo o ka ʻāʻī. ʻO ke kaula PET me ka viscosity o 0.80 dl/g e ʻoi aku ka maikaʻi o ke kaula i hana ʻia mai ka resin 0.60 dl/g ma ke ʻano o ka ikaika haʻihaʻi a me ke kūpaʻa hopena.

2.2 Elongation and Tension Paʻa

Hoʻopili pū ka viscosity i ke ʻano o ke kaula. Hōʻike ka PET kiʻekiʻe-viscosity i ka hoʻihoʻi hou ʻana i ka elastic, ʻo ia ka mea e hoʻomau i ka haʻalulu i ka manawa ke hoʻopaʻa ʻia nā ukana. Hiki i ka PET viscosity haʻahaʻa ke kikoo mau loa, e alakaʻi ana i nā haʻahaʻa haʻahaʻa i ka wā e hele ai.

2.3 Kūʻē Kūlohelohe

Wahi a ka ʻike ʻepekema waiwai, ʻoi aku ka maikaʻi o ka PET viscosity kiʻekiʻe i ka hōʻino ʻana o UV a me ka ʻelemakule wela ma mua o nā māka haʻahaʻa viscosity. Mālama kēia i ke kaula i kona ikaika i ka wā lōʻihi o ka mālama ʻana i waho a i ʻole ka holo moana.

3. Nā hopena o ka Viscosity hewa

3.1 Inā Haʻahaʻa loa ka Viscosity (< 0.60 dl/g)

• ʻO ke kaula liʻiliʻi : Hiki i ke kaula ke haki a moku paha i ka wā e hoʻopaʻa ʻia ai.

• Kaha haʻahaʻa haʻahaʻa : Ua hāʻule ke kaula ma lalo o nā ukana i hiki i ke kaula i kuhikuhi pono ʻia ke lawelawe.

• Hana like ʻole : ʻO nā ʻano like ʻole o ka pūʻulu a me ka hui ke kumu o ka pau ʻana o ka laina hana.

3.2 Inā Kiʻekiʻe ʻo Viscosity (> 0.95 dl/g)

• Nā pilikia kaʻina hana : He paʻakikī ka resin viscosity kiʻekiʻe extrude a kikoo, e alakai ana i ka ikehu kiʻekiʻe a me ka lole lako.

• ʻOʻoleʻa : Paʻa loa paha ke kaula e hoʻohālikelike i nā ʻano pūʻolo, e hōʻemi ana i ka paʻa o ka ukana.

4. Pehea ʻo Jushuo Packaging e hoʻomalu ai i ka viscosity

Ma Jushuo Packaging, ʻaʻole mākou e waiho i ka viscosity i ka manawa. Hoʻohana mākou i ka ʻenehana Solid State Polymerization (SSP) e kāohi a hoʻopaʻa i ka viscosity intrinsic o kā mākou resin PET.

Wahi a kā mākou ʻikepili hana, hiki i ka ʻenehana SSP ke hoʻoponopono pololei i ka viscosity i loko o ka pae 0.60 a 0.95 dl / g. Mālama kēia i kēlā me kēia pūʻulu o ke kaula PET e hoʻokō i ka ikaika tensile a me ka lōʻihi. Ke hōʻoia nei mākou i ka viscosity ma o ka hoʻāʻo ʻana i ka lab, e hōʻoia ana i ke kaula i hoʻopau ʻia e hāʻawi i ka hana i koi ʻia no nā noi ʻoihana kaumaha.

5. Ke Loiloi ana i ka Mana Viscosity o ka Mea Hoolako

5.1 Palapala

Ke koho ʻana i kahi mea hoʻolako kāʻei PET, e noi i nā kikoʻī kikoʻī. Hāʻawi ka mea hoʻolako hilinaʻi i nā palapala o ka viscosity intrinsic o ka resin a me nā waiwai mechanical o ke kaula i hoʻopau ʻia. Hōʻike kēia ʻike ʻike i ka mana viscosity kahi ʻāpana o kā lākou ʻōnaehana hoʻokele maikaʻi.

5.2 Laʻana hoʻāʻo

E noi i nā laʻana a hoʻāʻo iā lākou. E like me nā hana maikaʻi loa:

1. Ho'āʻo Tensile : E hōʻoia i ka ikaika haʻihaʻi e like me ka kikoʻī.

2. Ho'āʻo Elongation : E ana i ka nui o ke kaula i ʻō ma lalo o ka ukana.

3. Nānā Kiʻi : E nānā i nā hemahema o ka ʻili e hōʻike ana i ka hana maikaʻi ʻole.

Hōʻuluʻulu manaʻo

ʻO ka viscosity intrinsic ka kikoʻī huna e hoʻoholo ai i ka ikaika maoli o ke kaula PET (polyester strap). ʻO ka laulā maikaʻi loa o 0.60 a 0.95 dl / g e hōʻoia i ka lōʻihi o nā kaulahao polymer e hāʻawi i ka ikaika tensile kiʻekiʻe a me ka hoʻihoʻi elastic, ʻoiai ke waiho nei i ka hana no ka hana pono.

No nā mea kūʻai, ʻo ka ʻike ʻana i ka viscosity e kōkua i ka hoʻokaʻawale ʻana ma waena o nā mea hoʻolako kiʻekiʻe a me kēlā mau kihi ʻoki. Ma ka hōʻoia ʻana i ka mana viscosity, hiki iā ʻoe ke hōʻoia i ke kaula PET āu e kūʻai ai e hana pono i nā noi noi.

Ke kū nei ʻo Jushuo Packaging ma ke ʻano he mea hana poliester PET strap hilinaʻi, e hāʻawi ana i nā ʻōnaehana strapping plastic kiʻekiʻe i kākoʻo ʻia e nā makahiki he ʻumi o ka ʻike loea. Hoʻohana kā mākou mea hana ʻenehana 15,000㎡ i ka ʻenehana Solid State Polymerization (SSP) e hoʻomalu pono i ka viscosity mai 0.60 a i 0.95 dl/g, e hana ana i ka strapping PET kiʻekiʻe me 99% pass rates. Me ka mana hana makahiki ma mua o 20,000 tons, hōʻoia mākou i nā kaulahao lako pono a me ka uku hoʻokūkū no nā kauoha nui. Inā makemake ʻoe i ke kōkua me nā kikoʻī o ke kaula PET a i ʻole ka hōʻoia viscosity, e ʻoluʻolu e hoʻouna i leka uila i sales@jushuopackaging.com , a e hāʻawi kā mākou hui ʻoihana i ke kākoʻo hoʻokahi.
