ʻeke ulana ʻeke a me ka ʻenehana hana ʻeke ʻeke

Palakiʻeke i ulana ʻiahana ʻia me ka polypropylene (PP) ma ke ʻano he kumu maka, a ua hana ʻia e ka extrusion, kiʻi uea, ulana, ulana a me ka hana ʻeke.
ʻO ka Polypropylene kahi thermoplastic translucent a semi-crystalline me ka ikaika kiʻekiʻe, ka insulation maikaʻi, ka haʻahaʻa haʻahaʻa wai, ka wela thermoforming kiʻekiʻe, ka haʻahaʻa haʻahaʻa a me ka crystallinity kiʻekiʻe.ʻO ia ka mea nui o nā ʻeke i ulana ʻia.Hoʻokomo pinepine ʻia nā mea hoʻopiha i hoʻololi ʻia i nā fila aniani, nā mea hoʻopihapiha mineral, nā ʻōpala thermoplastic, a me nā mea like.

Loaʻa i nā ʻeke i ulana ʻia i nā ʻeke he nui nā mea hoʻohana.I kēia manawa, hoʻohana nui ʻia nā ʻeke i ulana ʻia no ka hoʻopili ʻana i nā huahana mahiʻai, ʻeke ʻeke sima, ʻeke meaʻai, ʻenekinia geotechnical, huakaʻi mākaʻikaʻi, nā mea hoʻokele wai, etc. ʻeke a me nā lole ulana like ʻole.ʻO ke kaʻina hana o nā ʻeke i ulana ʻia e like me kēia: ulana paʻi, ʻoki, a humuhumu i loko o nā ʻeke ulana.
Ma muli o nā mea hana i hoʻohana ʻia, hiki ke ʻoki mua ʻia a paʻi ʻia, a paʻi ʻia a ʻokiʻoki.Hiki i nā tailors automatic ke hoʻopau mau i ka paʻi, ʻokiʻoki, humuhumu a me nā kaʻina hana ʻē aʻe, a hiki ke hana ʻia i loko o nā ʻeke valve, nā ʻeke lalo, a me nā mea ʻē aʻe.ʻO ke kaʻina hana o nā ʻeke i ulana ʻia e hoʻohui a i ʻole nā ​​lole i ulana ʻia, nā mea uhi a me ka pepa a i ʻole ke kiʻiʻoniʻoni.Hiki ke ʻoki ʻia ka paipu a ʻāpana lole paha, paʻi ʻia, humuhumu ʻia a hana ʻia i loko o kahi ʻeke humuhumu maʻamau maʻamau, a i ʻole kuʻi ʻia, pelu ʻia, ʻoki ʻia, paʻi ʻia a humuhumu ʻia i loko o kahi ʻeke sima, a ʻo ka ʻāpana lole i loaʻa e hiki ke humuhumu, gluing, paʻi ʻana, ʻokiʻoki a hoʻopili ʻia i loko o nā ʻeke ʻeke ma lalo.Hiki ke wili ʻia a ʻōwili ʻia e hana i nā tarpaulins a me nā geotextiles.Hiki ke uhi ʻia ka lole maʻemaʻe a i ʻole ka uhi ʻole ʻia e hana i nā tarpaulins, geotextiles, etc.
Hoʻokaʻawale ʻia nā hōʻailona ʻenehana o ke kaʻina hana uea pālahalaha i ʻehā mau ʻāpana:

1. Helu helu hana mīkini.ʻO ka mea nui e hoʻokomo i ka ikaika tensile, ka ikaika tensile pili, ka elongation ma ka haki, ka wikiwiki laina, ka hoʻokaʻawale ʻana o ka laina;

2. Heluhelu hoʻololi kino a kemika.Aia ka nui o ka hoʻololi ʻana, ka ratio hui ʻana, ka ratio hoʻohui hoʻohui hana, a me ka ratio hui ʻana o nā ʻōpala a me nā mea hana hou;

3. Hōʻike ʻana i ke ana ʻana.He nui ka mānoanoa uea palahalaha, laula uea palahalaha a pela aku.

4. Ka helu rheological kino.Aia ka nui o ka ratio draft, ratio expansion, draft ratio a me retraction ratio;
ʻO ka mea polyethylene i loko o ke kaʻina hana ʻeke ʻeke ua wela, hoʻoheheʻe ʻia, plasticized a extruded stably e ka extruder;
E kaomi i loko o ke kiʻi cylindrical ma ke poʻo make;hoʻokomo i ke kinoea i hoʻopaʻa ʻia e hoʻonui i nā ʻōpū tubular;
E hoʻohana i ke apo ea hoʻoluʻu e hoʻolili a hoʻohua, huki i ka iwi herringbone splint a pelu ia;
Ma o ka wili wili, kaʻa kaʻa a me ka wili wili,
ʻO ka mea hope loa, hoʻokō ʻia ka ʻoki a me ka hoʻopaʻa ʻana i ka wela e hoʻopau ai i ka hana ʻana o ka ʻeke lining i loko, a ma hope ua hoʻopiha ʻia ka ʻeke.
ʻAʻole hiki ke hoʻokō ʻia ka polypropylene maʻemaʻe no ka hana ʻana i nā wili palahalaha, a pono e hoʻohui ʻia kekahi hapa o ka polyethylene kiʻekiʻe, calcium carbonate a me ka masterbatch kala.ʻO ka hoʻohui ʻana i kahi mea liʻiliʻi o ka polyethylene kiʻekiʻe hiki ke hōʻemi i ka viscosity a me ka hoʻoheheʻe ʻana o ka mea kahe i ka wā extrusion, hoʻonui i ka wai, hoʻomaikaʻi i ka paʻakikī a me ka palupalu o ka ʻeke palahalaha a me ka ʻeke i ulana ʻia, mālama i kekahi elongation i ka wā hoʻomaha, a hoʻomaikaʻi i ka haʻahaʻa. ka hopena wela o ka polypropylene..
Hiki i ka hoʻohui ʻana o ka polypropylene grafted ke hoʻemi i ka mahana hana a me ke kaomi.Hoʻomaikaʻi i ke kahe waiwai a me ka hoʻopili ʻana, a hoʻonui i ka ikaika tensile.Hiki i ka hoʻohui ʻana o ka calcium carbonate ke hoʻololi i nā hemahema o ka ʻike a me ka opacity, e hōʻemi i ka uila static ʻino i hana ʻia e ka friction i ka wā e hoʻolōʻihi ʻia a me ka ulana ʻana, e hoʻonui i ka hoʻopili ʻana i ka ʻīnika o nā hiʻohiʻona i paʻi ʻia, a e hōʻemi i ka hōʻemi maoli o nā huahana i hoʻopau ʻia i ka wā mālama.
