Piʻi nui mai ka hopohopo e pili ana i ka ʻike ʻana i ka wai ke nānā nā luna kūʻai i nā mea hoʻopaʻa no ka mālama ʻana ma waho, ka hoʻouna ʻana ma ke kai, a i ʻole nā ​​hale waihona wai. ʻO ka pane maʻalahi ʻaʻole, ʻaʻole e hōʻeha ka wai i ke kaula polyester. No ka mea he hydrophobic kona mau mole, ʻo ke kaula PET (Polyethylene Terephthalate) he ver

ʻO ke kaumaha nui loa e hiki ke paʻa i nā kaula pulupulu mai 180 kg a 1360 kg, e pili ana i ke ʻano o nā mea i hana ʻia ai lākou, ko lākou mānoanoa, a me ko lākou laulā. ʻO nā ʻōnaehana kāʻei o ka pulupulu bale hou, ʻoi aku ka nui o nā mea i hana ʻia mai nā mea PET ikaika kiʻekiʻe, ʻoi aku ka maikaʻi o ka ikaika tensile ʻoiai ʻo ia ka f

He aha nā ʻano maikaʻi loa o ka PP Strapping no ka Packaging Duty? ʻO ka ikaika haʻihaʻi o kēia mau mea strapping ʻenehana kiʻekiʻe ma waena o 150 a 230 kg, ʻo ia ka mea hiki ke hoʻohana ʻia.

ʻO Polypropylene PP Strap vs Polyester Strap: Pros and ConsNo ke koho ʻana ma waena o ke kaula polyester a me ke kaula polypropylene PP no ka ʻeke kalepa, he mea nui e ʻike i ka mea e ʻokoʻa ai lākou. ʻO nā kaula polypropylene ka koho ʻoi aku ka maikaʻi a me ka maʻalahi no ka noi māmā a me ka hana maʻamau.

ʻO ke kaula PET (polyester strap) kahi mea hoʻopaʻa ikaika kiʻekiʻe i hoʻohana ʻia ma nā ʻoihana ʻoihana koʻikoʻi kahi e koi ʻia ai ka ikaika e like me ke kila me ka ʻole o nā drawbacks o ke kila. Me ka ikaika tensile a hiki i 600 N/mm², ka hoʻopaʻa ʻana i ka hoʻopaʻapaʻa maikaʻi, a me ka hana ʻole o ka ʻōpala, ʻo ke kaula PET ka mea i koho ʻia no ka hui pū ʻana o ke kila, ka pulupulu bale, ka palletizing brick, ka hoʻopili ʻana i ka lāʻau, a me ka mālama ukana kaumaha. Ke ʻimi nei kēia alakaʻi i nā noi nui o ke kaula PET, e kōkua ana i ka poʻe ʻoihana kūʻai e hoʻomaopopo i kahi a me ke kumu i kuhikuhi ʻia ai kēia ʻano mea.

ʻO ka nānā ʻana i ke kaula PET (polyester strap) i nā hoʻouna ma mua o ka ʻae ʻia ʻana he mea nui ia no ka hōʻoia ʻana i ka kūlike o ka maikaʻi a me ka pale ʻana i nā pilikia hana. Hoʻopili kēia alakaʻi i kahi kaʻina nānā ʻōnaehana e uhi ana i ka hōʻoia ʻana i ka ikaika haʻihaʻi, ka pololei o ke ana, ka maikaʻi o ka hoʻopau ʻana o ka ʻili, ka pololei o ka ʻōwili ʻana, ke ʻano o ka pahu, a me ka loiloi palapala. ʻO ka hoʻokō ʻana i kēia mau ʻanuʻu nānā e kōkua i ka poʻe ʻoihana kūʻai e ʻike i nā pilikia maikaʻi ma mua o ka hoʻopili ʻana i nā hana hoʻopili.

ʻO ka nīnau 'ʻoi aku ka maikaʻi o ka PP ma mua o ka PET moisture barrier?' he mea maʻamau i waena o nā poʻe loea e koho ana i nā mea no nā noi e pili ana i ka wai. Wahi a ka ʻikepili hoʻāʻo i paʻi ʻia, hāʻawi ka kiʻiʻoniʻoni polypropylene (OPP) oriented i ka hana pale wai ma kahi o 3 mau manawa ʻoi aku ka maikaʻi ma mua o ka PET o ka mānoanoa like.

He kūpono loa ke kaula PET (polyester strap) no nā noi mālama waho. Wahi a Signode, pale ʻo PET i ka UV, ka makū, a me ka nui o ka hoʻololi ʻana o ka mahana, e kūpono ana ia no nā ukana i mālama ʻia ma waho a i ʻole nā ​​kūlana paʻakikī.

ʻO ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana i ke kaula PP (polypropylene strap) he mea nui ia no ka palekana o ka ukana a me ka hilinaʻi o ka pahu. Hoʻopili kēia alakaʻi i nā loina hoʻomalu ʻana, nā ʻano hoʻopaʻa ʻana (sealing wela a me friction welding), nā hewa maʻamau e pale aku ai, a me nā hana maikaʻi loa no ka hana ʻana i ka lima a me ka ʻakomi. Wahi a ka loiloi ʻoihana, hoʻopaʻa ʻia ka haʻalulu a me ka sila ʻana i ka hāʻule ʻole o ka ukana a hōʻemi i nā koi pōʻino huahana.

ʻO ke koho ʻana i ka laulā kūpono a me ka mānoanoa o ka strapping PP pono e loiloi i kāu paona paona, nā kūlana hoʻouna, a me ke ʻano noi. No nā ukana liʻiliʻi, aia ma waena o 9 a me 12 mm ākea a me 0.35 a me 0.5 mm ka mānoanoa. No nā ukana nui, pono ka laulā ma waena o 15 a 19 mm a me ka mānoanoa ma waena
