ʻO ka hana ʻana a me ka hana ʻana i nā plastik, ke kaʻina hana o ka extrusion plastik

ʻO ka extrusion plastik kahi hana kahi e hoʻoheheʻe ʻia ai ka plastic a hana ʻia i ʻano mau.Hoʻohana ʻia kēia kaʻina hana no ka hana ʻana i nā mea e like me ka paipu, fencing, tubing, wire insulation, window frames, a me railing…

ʻO ka hana ʻana a me ka hana ʻana i nā plastik

ʻO nā plastik he polymers me nā kaumaha molekala kiʻekiʻe.He mea maʻamau ka plastics i nā ʻano huahana like ʻole, mai nā kaʻa kaʻa a hiki i nā paipu.ʻO ka hana ʻana a me ka hana ʻana i nā plastik he ʻekolu mau ʻanuʻu kumu: 1) ka hāʻawi ʻana i kekahi mau hiʻohiʻona i nā resins plastik me nā mea hoʻohui kemika, me nā lubricants, nā mea pale ahi, nā kala a me nā plasticizers;2) ka hoʻololi ʻana i nā mea maka (plastic granules, pellets, sheets, fluids or preformed plastics) i waena a i ʻole ka hopena hope;a me 3) ka hoʻopau ʻana i ka huahana ma o ka hoʻoheheʻe ʻana / hana ʻana, e like me ka hoʻoheheʻe ʻana a i ʻole extrusion.Hoʻopili ʻia ka hoʻoheheʻe ʻia ʻana i nā granules a i ʻole nā ​​pellets i kahi kūlana wai a me ke kaomi ʻana i ka palaki wai i loko o nā poni anu no ka hoʻonohonoho ʻana.Hoʻokomo ʻia ka extrusion i ka hoʻokuʻu ʻana i nā mea plastik wai ma o ka make e hana i nā ʻano lōʻihi a mau, e like me nā paipu a i ʻole nā ​​paipu.

ʻO ke kaʻina hana kumu o ka Extrusion Plastic

Hoʻohana ʻia ke kaʻina hana i ka resin plastic, ʻo ia nā peʻa plastik liʻiliʻi, i hānai ʻia ma o ka hopper i loko o ka pahu wela o ka extruder.Ma laila, hoʻoheheʻe ʻia ka wili, e huli maʻamau i ka 120 rpm, e hoʻoheheʻe ʻia ma nā wahi āpau mai 392 degere a 527 degere Fahrenheit, ma muli o ka polymer i hana ʻia ai ka resin.No ke kōkua ʻana i ka hōʻemi ʻana i ka hopena o ka wela nui ʻana o ka resin, hoʻonui mālie ʻia ka wela mai kekahi ʻaoʻao o ka barela a i kekahi.

Ma ke alo o ka pahu, aia kahi pale e hoʻolei ʻia ai ka resin hehee e kōkua i ka kānana ʻana i nā mea i haumia i ka resin.I ka manawa e hele ai ka resin thermoplastic hehee i ka pale, e hoʻouna ka pahu hānai i ka resin ma o ka make kino, a laila hāʻawi i ka huahana i kona ʻike.

Hiki ke hana mau ʻia kēia ʻano a i ʻole ka ʻaoʻao, i kēlā me kēia lōʻihi.

ʻO ka hope, pono e hoʻomaloʻo ka huahana.Hana ʻia kēia me ka ʻauʻau wai.Hoʻopaʻa maikaʻi ka plastik i ka wela, no laila e lōʻihi ke kaʻina hoʻomaha.Ma muli o kēia, hoʻopaʻa pinepine ʻia ka ʻauʻau wai a hoʻohana ʻia kahi ʻōpala e mālama i ka huahana mai ka nalowale ʻana i kona ʻano i ka wā e maʻalili ai.
