Hana ʻia nā ʻeke ʻeke palaki i ka polypropylene (PP) ma ke ʻano he kumu nui, ka mea i hoʻokuʻu ʻia, huki ʻia me ka hao, ulana hou ʻia, ulana ʻia, a hana ʻia i ʻeke pahu.
ʻO ka PP he mea aniani, semi-crystalline thermosetting plastic me ka paʻakikī kiʻekiʻe, nā waiwai insulation maikaʻi, haʻahaʻa haʻahaʻa wai, kiʻekiʻe ambient wela, haʻahaʻa haʻahaʻa pili, a me ke aniani aniani kiʻekiʻe.ʻO ia ka mea nui no ka hana ʻana i nā ʻeke ʻeke.ʻO nā mea hoʻopihapiha hoʻololi i hoʻololi pinepine ʻia i nā fibers aniani, nā mea hoʻopiha mineral, nā ʻōpala thermoplastic, a me nā mea like.
He ākea loa ka laulā o ka hoʻohana ʻana i nā ʻeke ʻeke plastik.I kēia pae, ʻo nā noi nui o nā ʻeke ʻeke plastik ʻo ia ka ʻeke o waho o nā huahana mahiʻai, ka ʻeke waho o nā ʻeke i ulana ʻia i ka meaʻai, nā mea ʻai meaʻai, ka ʻenekinia geological, ka halihali huakaʻi hoʻomaha, ka hakakā ʻana i ka wai a me nā mea pilikia, etc. ʻano nui o nā ʻeke ʻeke: ʻeke ʻeke pepa (nā ʻeke ʻeke kiʻiʻoniʻoni ʻole), nā ʻeke ʻeke plastik composite a me nā ʻeke i ulana ʻia.ʻO ke kaʻina hana o nā ʻeke ʻeke plastik: lilo nā ʻeke i ulana ʻia i ʻeke ʻeke ma hope o ka hoʻopili ʻana a me ka paʻi ʻana, ka ʻoki ʻana a me ka humuhumu.
Ma muli o ka mīkini a me nā mea hana i hoʻohana ʻia, hiki ke ʻoki ʻia i ka laser a laila paʻi ʻia, a paʻi ʻia a laila ʻoki ʻia ka laser.Hiki ke hoʻomau i ka mīkini ʻoki ʻoki ʻoki laser i ke kaʻina hana o ka paʻi paʻi, ʻoki ʻoki laser, mīkini humuhumu, a me nā mea ʻē aʻe, a hiki ke hana ʻia i loko o nā ʻeke valve, nā ʻeke lalo, a me nā mea ʻē aʻe. hiki ke hana i ka eke.ʻO ke kaʻina hana o nā ʻeke ʻeke plastik composite e hoʻopili i nā ʻeke i ulana ʻia, nā pōhaku i hoʻohui ʻia a i ʻole nā kiʻiʻoniʻoni no ka hoʻolauleʻa ʻana a i ʻole ka uhi ʻana.Hiki ke ʻoki ʻia nā ʻōwili i loaʻa a i ʻole nā lau a me nā ʻōwili i ka laser, ʻoki ʻia a paʻi ʻia a humuhumu ʻia no ka hana ʻana i nā ʻeke humuhumu maʻamau.Hiki iā lākou ke wehe i nā puka, ka ʻokiʻoki ʻana i ka ʻaoʻao, ka ʻoki ʻana i ka laser, ka paʻi paʻi ʻana, ke humuhumu ʻoki ʻoki a me nā ʻeke i ulana ʻia.Hiki ke hoʻopili ʻia ka pepa i loaʻa me ka seam, ka paʻi paʻi, ka ʻoki ʻana i ka laser, ka hoʻopaʻa ʻana i ka uhi a me ka ʻeke ʻeke.Hiki iā ia ke welded, waiho ʻia, crimped, hana ʻia i loko o nā hale lāʻau a me nā geotextiles non-woven.Hiki ke hana hou a hana hou ʻole ʻia nā looms flat, nā geotextiles non-woven, etc. Hiki ke hana pinepine ʻia ka lole pahu pahu a ʻaʻole paha.
Hoʻokaʻawale ʻia nā hōʻailona hana o ke kaʻina hana mīkini kiʻi kiʻi kiʻi kiʻi i ʻehā mau ʻāpana:
1. Waiwai helu helu hana kino.Loaʻa ka hapa nui o nā ʻāpana e like me ka ikaika haʻihaʻi, ka ikaika haʻihaʻi pili, ka ikaika tensile, ka wikiwiki angular, a me ka nui;
2. Nā waiwai helu o nā mea i hoʻololi ʻia me ke kemika.Hoʻopili nui ia i ka hui ʻana i nā mea i hoʻololi ʻia, ka hoʻomākaukau ʻana i ka hui ʻana, ka hoʻohui ʻana i ka lākiō o nā mea hoʻololi, a me ka lakio o ka ʻōpala regenerated granular compound fertilizer;
3. ʻO ka helu kuhikuhi kikoʻī o ka hoʻomanawanui.Loaʻa ia i ka mānoanoa o ka mīkini kiʻi uea plastik a me ka laulā o ka uea palahalaha.
4. Waiwai kuhikuhi rheological waiwai kino.Loaʻa ka nui o ka lāki hoʻokaʻawale yarn, ratio inflation, ratio draft and shrinkage ratio;
ʻO ka ʻenehana hana ʻeke ʻeke laina kiʻekiʻe i hoʻomehana ʻia e kahi extruder, hoʻoheheʻe ʻia a hoʻokuʻu ʻia me ka maʻalahi;
E kaomi i ka ʻilika ʻano pahu i loko o kahi kiʻi kiʻiʻoniʻoni pahu;komo e hoemi i ka puhi lepo a hooulu i ka ohu paipu;
ʻO ka herringbone-like hair straightening splint ua hoʻomaloʻo ʻia a hoʻohālikelike ʻia e ke apo ea anuanu, a lawe ʻia ka traction i ka hoʻololi ʻana;
Ua huki ʻia ka ʻōnaehana hoʻokele i ka wili wili ma o ka wili kāʻei traction;
ʻO ka hope, hoʻokō ʻia ka ʻoki ʻana i ka laser, hana ʻia ka ʻeke lining e ke kaʻina hoʻoheheʻe wela, a ma hope ua ʻeke ʻia ka hua.
ʻAʻole hiki i ka polypropylene maʻemaʻe ke hoʻokō i nā pono o nā mīkini kaha kiʻi uea plastik, akā pono nō hoʻi e hoʻohui i kahi pākēneka o ka polyethylene, calcium bicarbonate a me ka masterbatch kala.ʻO ka hoʻohui ʻana i kahi liʻiliʻi o ka polyethylene i ka wā o ke kaʻina extrusion holoʻokoʻa hiki ke hōʻemi i ka viscosity a me ka hoʻoheheʻe ʻana o ka kahe waiwai, hoʻomaikaʻi i ka wai, hoʻomaikaʻi i ka ductility a me ka maʻalahi o ka mīkini kiʻi uea plastik a me nā ʻeke ʻeke plastik, mālama i kahi ikaika tensile, a hoʻomaikaʻi i ka polypropylene ultra-low wela pōʻino.
