Mea hana ʻoihana o nā mīkini thermoforming.
He aha nā mea palaki i kūpono no nā Mīkini Thermoforming Multi-station?
ʻO PVC, PET, PS, e like me nā mea maka, e hoʻololi i ka mold i hoʻokahi mīkini i ka hana ʻana i nā poʻi, nā uhi, nā pā, nā pā, nā pahu, nā meaʻai a me nā pā lapaʻau, etc.
Polyvinyl chloride (PVC)
ʻO ka polyvinyl chloride, i hoʻopau ʻia e like me PVC, he polymer i hana ʻia e ka polymerization radical manuahi o ka vinyl chloride monomer ma lalo o ka hana a nā mea hoʻomaka e like me nā peroxides a me nā pūhui azo, a i ʻole ma o ka mālamalama a me ka wela. ʻIke ʻia he pauda keʻokeʻo, ʻona ʻole a ʻala ʻole, me ke kaumaha molekala maʻamau mai 50,000 a 110,000 (no ka PVC maʻemaʻe i hana ʻia ma ka ʻoihana). ʻO 1.35–1.45 kona mānoanoa pili, e hōʻike ana i ka haʻahaʻa haʻahaʻa o ka wai a me ke kinoea permeability (PVC maʻemaʻe). ʻAʻole ia e hoʻoheheʻe i ka wai, ka ʻaila, ka waiʻona, a me ka vinyl chloride, akā hiki ke hoʻoheheʻe ʻia i nā ketones, esters, a me nā mea hoʻoheheʻe hydrocarbon chlorinated. Hoʻohanohano ka Polyvinyl chloride (PVC) i ke kūpaʻa kemika ikaika a he insulator uila maikaʻi; akā naʻe, ʻaʻole paʻa loa ka hopena. He mea nui e hoʻomaopopo ʻaʻole paʻa kēia mea i ka wā e ʻike ʻia ai i ka oxygen a me ka wela, e maʻalahi ai i ka hōʻino.
Ma ka hoʻohui ʻana i nā mea hoʻololi i ka hopena a me nā mea hoʻoponopono kino kino i ka PVC, a ukali ʻia e ka hui ʻana, ka plasticizing, a me ka calendering, hana ʻia nā ʻāpana aniani. Ma o ka thermoforming, hiki ke hana ʻia i loko o nā ipu aniani aniani a i ʻole hoʻohana ʻia no ka ʻōpala i hana ʻia me ka vacuum, e lawelawe ana ma ke ʻano he mea hoʻopihapiha maikaʻi loa a me nā mea hoʻonaninani.
E loaʻa iā ʻoe ka PVC a puni ʻoe no ka mea ʻaʻole ia e pale i ka lapalapa a mālama pono i ka wela. ʻO ke poʻo wikiwiki: ʻoiai e kū ikaika ana i nā kinikini he nui a he insulator uila maikaʻi loa ia, hiki ke maʻalahi a ʻaʻole loaʻa ka hopena paʻakikī. He mea maʻalahi hoʻi ia i ka loaʻa ʻana o ka oxygen a me ka wela kiʻekiʻe i ka wā lōʻihi, hiki ke hoʻohaʻahaʻa.
Polyethylene Terephthalate (PET)
ʻO PET ka mea hana o nā plastic māmā a ikaika. Inā ua paʻa ʻoe i ka ʻōmole soda a i ʻole kahi pahu meaʻai maʻemaʻe, ʻike ʻoe i ke ʻano o ka PET: ke aniani aniani, ʻālohilohi, a paʻakikī. He mea ʻoi aku ka maikaʻi i ka ʻeke.
Eia ka mea e pono ai ia mea:
ʻO ka ikaika a me ka māmā: He mea ikaika loa a paʻa i ka nawaliwali—3 a 5 mau manawa ʻoi aku ka pale ʻana i ka hopena ma mua o nā kiʻi ʻoniʻoni ʻoniʻoni ʻē aʻe-a pelu ia me ka nāwaliwali ʻole. Eia kekahi, he aniani aniani maoli ia me ka nani o ka nani e hoʻonanea ai nā huahana.
He Paʻa Nui: He hana maikaʻi loa ia no ka mālama ʻana i ka oxygen, ka makū, a me ka pilau, ʻo ia ke kumu e mālama ai i kāu meaʻai hou a me kāu soda fizzy.
Paʻa a palekana: Hoʻohana ʻo ia i nā mahana mai kahi hau hau -70°C a hiki i 65°C me ka pau ʻole o kona ikaika. He kū'ē i nā aila a me nā momona, a ʻaʻohe mea ʻawaʻawa a palekana no ka pili ʻana i ka meaʻai.
Palekana: Hoʻopaʻa ia i ke kukui ultraviolet, pale i ka mea o loko mai ka pōʻino o ka lā.
Polystyrene (PS)
ʻIke maikaʻi ʻia ka Polystyrene ma nā ʻano ʻelua: ʻo ia ka ʻiʻo paʻa, ka ʻilika maʻemaʻe (e like me nā pahu CD) a i ʻole he mea hoʻopuʻi ʻia (Styrofoam™). He mea maʻalahi, maʻalahi ka waiwai no kona mālamalama a me nā waiwai insulation.
ʻAʻole waihoʻoluʻu ka Polystyrene, ʻae koke i ka pigmentation, a he haʻahaʻa haʻahaʻa haʻahaʻa e like me ka polypropylene (PP) a me ka polyethylene (PE). Hōʻike ia i nā waiwai uila koʻikoʻi, ʻoi aku ka maikaʻi o nā hiʻohiʻona kiʻekiʻe, ʻelua wale nō i ka PTFE a me PPO. Eia kekahi, ʻo kona kūpaʻa māmā ka lua wale nō i ka polymethyl methacrylate (PMMA), ʻoiai ʻo kona pale ʻana i ka radiation ka ikaika loa ma waena o nā plastics āpau. ʻO ka hiʻohiʻona koʻikoʻi o ka polystyrene ʻo ia kona kūpaʻa wela maikaʻi loa a me ka kahe ʻana i ka wā e hoʻoheheʻe ai, e maʻalahi ai ka hana a kūpono no ka hana nui. Hōʻike ia i ka hoʻohaʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa dimensional maikaʻi i nā huahana i hoʻoheheʻe ʻia.
No ka ʻike ʻana pehea e hiki ai ke hoʻohālikelike ʻia kēia mea i nā huahana hope, kono mākou iā ʻoe e ʻike i kā mākou Mīkini Thermoforming Multi-station . ʻO ia ka hopena paʻa, haʻahaʻa haʻahaʻa e hoʻomaka koke i kāu laina hana pono.
Mea hana ʻoihana o nā mīkini thermoforming.
