Me nā haneli o nā waiwai a me nā ʻenekinia resins i loaʻa ma ka mākeke i kēia lā, ʻo ke kaʻina koho mea no ka hana hoʻoheheʻe ʻana i ka plastik hiki ke ʻike pinepine ʻia i ka wā mua.
Ma DJmolding, hoʻomaopopo mākou i nā pono kūʻokoʻa a me nā waiwai o nā ʻano plastics like ʻole a hana pū me nā mea kūʻai aku e ʻike i ka mea kūpono loa no kā lākou papahana.
He aha ke ʻano o nā resins plastik?
Noho mākou i kahi honua i hoʻopuni ʻia e nā resins plastic. Ma muli o kā lākou mau waiwai i makemake nui ʻia, hiki ke loaʻa nā resins plastic i nā mea āpau mai nā hue a me nā ipu i nā ʻenehana a me nā mea lapaʻau a me nā mea hou aku. Hoʻokomo ʻia nā resins plastik i kahi ʻohana nui o nā mea i loaʻa i kēlā me kēia me ko lākou mau waiwai ponoʻī e kūpono iā lākou no nā noi like ʻole. Ke koho ʻana i ka resin kūpono no kāu papahana, he mea nui e hoʻomaopopo i ka mea a kēlā me kēia ʻano e hāʻawi ai.
He aha ka ʻokoʻa ma waena o Resin a me Plastic?
ʻO ka resin a me ka plastic he mau mea koʻikoʻi nui, akā loaʻa kekahi mau ʻokoʻa koʻikoʻi, me:
*Kumu: ʻOiai ke ulu maoli nei nā resins i nā mea kanu, he synthetic ka plastics a loaʻa pinepine ʻia mai nā petrochemical.
*Wehewehe: ʻO ka plastik kahi ʻano o ka resin synthetic, ʻoiai nā resins he mau mea amorphous i hiki ke semi-paʻa a paʻa paha.
* Paʻa a me nā haumia: ʻOi aku ka paʻa o nā plastik ma mua o ka resin a nele i nā haumia. Me nā resins, ʻaʻole hiki ke pale ʻia nā haumia.
*Oolea: ʻOiʻaʻa a paʻakikī ka plastik, ʻoiai ʻo ka resin ka mea maʻamau he mea gluey a viscous.
* Ka hopena o ke kaiapuni: No ka mea he kūlohelohe ka resin, hāʻawi ia i kahi koho ʻoi aku ka maikaʻi o ke kaiapuni i ka plastic. Hoʻohaʻahaʻa mālie ʻia ka plastik a loaʻa pinepine nā mea hoʻohui ʻona e hiki ke alakaʻi i ka pollution kaiapuni.
ʻO nā noi maʻamau no ka hoʻoheheʻe ʻia ʻana o ka Resin
Hoʻopili ʻia ka hoʻoheheʻe ʻana i ka plastik me ka nui o nā mea resin. Ke hoʻoholo nei i ka resin kūpono no kāu mau pono, he mea nui e hoʻomaopopo i nā pono o kāu noi ponoʻī. ʻO nā noi maʻamau no nā resins injection molding like ʻole:
ABS
Hoʻohana ʻia ʻo ABS i hoʻoheheʻe ʻia i loko o nā ʻano noi like ʻole, e like me nā pā pākiki no nā puka uila, ke poʻo pale, nā kī kī, nā mea uila, a me nā ʻāpana kaʻa e like me nā ʻāpana kino kaʻa, nā uhi huila, a me nā dashboards. Hoʻohana ʻia ia no ka nui o nā lako hana, nā mea haʻuki, a me nā mea kūʻai aku.
Celson (Acetal)
Ma muli o kona haʻahaʻa haʻahaʻa o ka friction, ua kūpono ʻo Celson i hoʻoheheʻe ʻia no nā huila pulley, nā kāʻei conveyor, nā mīkini, a me nā bearings. Hiki ke ʻike ʻia kēia mea i loko o nā ʻāpana ʻenekinia hana kiʻekiʻe, nā ʻōnaehana laka, nā pū ahi, nā papa aniani, a me nā mea hoʻopaʻa.
ʻO Polypropylene
Hoʻohana ʻia ka polypropylene injection-molding i nā ʻano like ʻole o ka ʻoihana, ʻoihana, a me nā noi mea kūʻai aku. No ka laʻana, hiki ke loaʻa i loko o nā kino mea hana mana, nā mea hana, nā mea hoʻopili, nā mea haʻuki, nā pahu mālama, a me nā mea pāʻani keiki.
HIPS
Ma muli o ka loaʻa ʻana o ka HIPS i ka ikaika hopena kiʻekiʻe, hiki ke loaʻa i nā mea hana, nā mea paʻi paʻi, nā hōʻailona, a me nā mea hana. ʻO nā polokalamu maʻamau ʻē aʻe nā mea pāʻani a nā keiki a me nā mea uila.
LDPE
Ma muli o kona maʻalahi a me ke kū'ē i ka makū a me nā kinikona, hoʻohana pinepine ʻia ʻo LDPE i hoʻoheheʻe ʻia no nā noi me nā ʻāpana lāʻau lapaʻau, nā uea a me nā insulators uwea, nā pahu hana, a me nā mea pāʻani keiki.
Nā mea nui e noʻonoʻo ai i ke koho ʻana i kahi mea hoʻoheheʻe injection
ʻO nā ʻāpana plastik maʻamau mai DJmolding e hōʻoia e koho ʻoe i ka resin kūpono no kāu papahana, e hoʻomanaʻo i nā ʻano like ʻole:
*Ka ikaika hopena - Pono kekahi mau noi i ka ikaika kumu ma mua o nā mea ʻē aʻe, no laila e hoʻoholo ʻia ka ikaika hopena o ka resin Izod mai ka hoʻomaka ʻana.
*Ka ikaika tensile — ʻO ka ikaika tensile hope loa, a i ʻole ka ikaika hope loa, e ana i ke kūʻē ʻana o ka resin i ka haʻalulu a me kona hiki ke kū i ka ukana i hāʻawi ʻia me ka huki ʻole ʻana.
*Modula hoʻololi o ka elasticity — E pili ana kēia i ke kiʻekiʻe o ka hiki ke hoʻopololei ʻia kahi mea me ka pōʻino ʻole a hoʻi hou i kona ʻano kumu.
*Ka wela wela - He mea koʻikoʻi kēia no nā noi e koi ana i ka hana insulating a i ʻole ka hoʻomanawanui ʻana no nā pae wela like ʻole.
*Ka hoʻoheheʻe wai — Hoʻokumu ʻia kēia ma ka pākēneka o ka wai i lawe ʻia e kekahi mea ma hope o 24 mau hola o ka hoʻoinu ʻana.
Koho Maikaʻi me DJmolding
ʻO Djmolding ka mea hana hoʻoheheʻe ʻia, hana i nā ʻāpana plastik me ka acrylic (PMMA), acrylonitrile butadiene styrene (ABS), nylon (polyamide, PA), polycarbonate (PC), polyethylene (PE), polyoxymethylene (POM), polypropylene (PP), polystyrene (PS) a pēlā aku
ʻO ke koho ʻana i ka mea kūpono mai ka hoʻomaka ʻana ʻaʻole ia e mālama wale iā ʻoe i ka manawa, a me ke kālā akā e hōʻoia pū kekahi i ka hana maikaʻi loa a me ka hana. E noʻonoʻo pono i kāu mau koho, a e kamaʻilio pū me ka mea hoʻoheheʻe ʻike i ka ʻike e kōkua i ka hoʻoholo ʻana i ke koho kūpono.
