1. Hana AS
He copolymer propylene-styrene ʻo AS, i kapa ʻia hoʻi ʻo SAN, me ka nui o ka density ma kahi o 1.07g/cm3. ʻAʻole ia e maʻalahi i ka haki ʻana o ke koʻikoʻi kūloko. ʻOi aku ka kiʻekiʻe o kona transparency, ʻoi aku ka mahana palupalu a me ka ikaika o ka hopena ma mua o PS, a ʻoi aku ka maikaʻi ʻole o ke kūpaʻa ʻana i ka luhi.
2. Hoʻopili ʻana o AS
Nā pā, nā kīʻaha, nā ipu ʻaina, nā keʻena pahu hau, nā pihi, nā mea pono kukui, nā mea hoʻonaninani, nā aniani mea kani, nā pahu hoʻopili, nā pepa kākau, nā kukui kinoea, nā ʻauamo palaki niho, a pēlā aku.
3. Nā kūlana hana AS
ʻO ka mahana hana o AS ma ke ʻano laulā he 210 ~ 250 ℃. He maʻalahi kēia mea e omo i ka makū a pono e hoʻomaloʻo ʻia no ka ʻoi aku ma mua o hoʻokahi hola ma mua o ka hana ʻana. ʻOi aku ka ʻino o kona kahe ma mua o PS, no laila ʻoi aku ka kiʻekiʻe o ke kaomi injection, a ʻoi aku ka maikaʻi o ka hoʻomalu ʻia ʻana o ka mahana o ka mold ma 45 ~ 75 ℃.
- ʻABS
1. Hana ABS
ʻO ABS ka acrylonitrile-butadiene-styrene terpolymer. He polymer amorphous ia me ka density ma kahi o 1.05g/cm3. Loaʻa iā ia ka ikaika mechanical kiʻekiʻe a me nā waiwai piha maikaʻi o "vertical, tough and steel". He plastic ʻenekinia i hoʻohana nui ʻia ʻo ABS me nā ʻano like ʻole a me nā hoʻohana ākea. Ua kapa ʻia hoʻi ʻo "general engineering plastic" (ua kapa ʻia ʻo MBS ʻo ABS transparent). He maʻalahi ke hoʻoponopono a me ke kaʻina hana, ʻaʻole maikaʻi ke kūpaʻa kemika, a maʻalahi hoʻi ke hoʻopili ʻia nā huahana.
2. Hoʻopili ʻia ʻana o ABS
Nā mea hoʻoili pamu, nā bearings, nā lima, nā paipu, nā pahu o nā mīkini uila, nā ʻāpana huahana uila, nā mea pāʻani, nā pahu uaki, nā pahu mea kani, nā pahu wai, nā pahu waiho anu a me nā pahu o loko o ka pahu hau.
3. Nā ʻano hana ABS
(1) He kiʻekiʻe ka hygroscopicity o ka ABS a he haʻahaʻa ke kūpaʻa ʻana i ka mahana. Pono e hoʻomaloʻo piha ʻia a hoʻomehana mua ʻia ma mua o ka hoʻoheheʻe ʻana a me ka hana ʻana e kāohi i ka nui o ka makū ma lalo o 0.03%.
(2) ʻOi aku ka liʻiliʻi o ka viscosity heheʻe o ka resin ABS i ka mahana (ʻokoʻa mai nā resins amorphous ʻē aʻe). ʻOiai ʻoi aku ka kiʻekiʻe o ka mahana injection o ABS ma mua o PS, ʻaʻohe ona pae piʻi mahana e like me PS, a ʻaʻole hiki ke hoʻohana ʻia ka hoʻomehana makapō. No ka hōʻemi ʻana i kona viscosity, hiki iā ʻoe ke hoʻonui i ka wikiwiki o ka wili a i ʻole e hoʻonui i ke kaomi/wikiwiki injection e hoʻomaikaʻi i kona kahe ʻana. ʻO ka mahana hana maʻamau he 190 ~ 235 ℃.
(3) ʻO ka mānoanoa heheʻe o ABS he waena, ʻoi aku ka kiʻekiʻe ma mua o PS, HIPS, a me AS, a ʻoi aku ka maikaʻi ʻole o kona kahe ʻana, no laila pono ke kaomi injection kiʻekiʻe.
(4) Loaʻa i ka ABS kahi hopena maikaʻi me nā wikiwiki injection waena a waena (ke ʻole nā ʻano paʻakikī a me nā ʻāpana lahilahi e koi i nā wikiwiki injection kiʻekiʻe), ua maʻalahi ka nozzle o ka huahana i nā māka ea.
(5) He kiʻekiʻe ke ana wela o ka hoʻoheheʻe ʻana o ABS, a hoʻoponopono pinepine ʻia kona mahana hoʻoheheʻe ma waena o 45 a me 80°C. I ka hana ʻana i nā huahana nui aʻe, ʻo ka mahana o ka hoʻoheheʻe paʻa (ʻōmole mua) ma kahi o 5°C ke kiʻekiʻe ma mua o ka hoʻoheheʻe neʻe (ʻōmole hope).
(6) ʻAʻole pono e noho lōʻihi ka ABS i loko o ka pahu wela kiʻekiʻe (pono e emi ma lalo o 30 mau minuke), a i ʻole e pala maʻalahi a melemele.
- PMMA
1. Hana o PMMA
He polymer amorphous ka PMMA, i ʻike nui ʻia ʻo plexiglass (sub-acrylic), me ka nui o ka density ma kahi o 1.18g/cm3. Loaʻa iā ia ka transparency maikaʻi loa a me ka transmittance māmā o 92%. He mea optical maikaʻi ia; loaʻa iā ia ke kūpaʻa wela maikaʻi (kū'ē wela). ʻO ka mahana deformation he 98°C). Loaʻa i kāna huahana ka ikaika mechanical waena a me ka paʻakikī o ka ʻili haʻahaʻa. Hiki ke kahakaha maʻalahi ʻia e nā mea paʻakikī a waiho i nā kaha. Ke hoʻohālikelike ʻia me PS, ʻaʻole maʻalahi ke palupalu.
2. Ka hoʻohana ʻana o PMMA
Nā aniani mea kani, nā huahana optical, nā mīkini uila, nā lako lapaʻau, nā hiʻohiʻona moakaka, nā mea hoʻonaninani, nā aniani lā, nā niho kuʻi, nā papa hoʻolaha, nā panela uaki, nā kukui hope kaʻa, nā pale makani, a pēlā aku.
3. Nā ʻano hana o PMMA
He paʻakikī nā koi hana o ka PMMA. He maʻalahi loa ia i ka makū a me ka mahana. Pono e hoʻomaloʻo loa ʻia ma mua o ka hana ʻana. He kiʻekiʻe iki kona mānoanoa heheʻe, no laila pono e hoʻoheheʻe ʻia ma kahi mahana kiʻekiʻe (219 ~ 240 ℃) a me ke kaomi. ʻOi aku ka maikaʻi o ka mahana o ka mold ma waena o 65 ~ 80 ℃. ʻAʻole maikaʻi loa ke kūpaʻa wela o ka PMMA. E hōʻino ʻia e ka mahana kiʻekiʻe a i ʻole e noho ana ma kahi mahana kiʻekiʻe no ka lōʻihi. ʻAʻole pono e kiʻekiʻe loa ka wikiwiki o ka wili (ma kahi o 60rpm), no ka mea, he maʻalahi ke hana ma nā ʻāpana PMMA mānoanoa. Pono ka hanana "void" i nā puka nui a me nā kūlana injection "kiʻekiʻe o ka mahana mea, kiʻekiʻe o ka mahana mold, wikiwiki lohi" e hana ai.
4. He aha ka acrylic (PMMA)?
He palakika maopopo a paʻakikī ka Acrylic (PMMA) i hoʻohana pinepine ʻia ma kahi o ke aniani i nā huahana e like me nā puka makani hiki ʻole ke wāwahi ʻia, nā hōʻailona i hoʻomālamalama ʻia, nā kukui lani a me nā canopies mokulele. No ka ʻohana koʻikoʻi o nā resins acrylic ka PMMA. ʻO ka inoa kemika o ka acrylic he polymethyl methacrylate (PMMA), he resin synthetic i polymerized mai ka methyl methacrylate.
ʻIke ʻia ʻo Polymethylmethacrylate (PMMA) ʻo ia hoʻi ka acrylic, ke aniani acrylic, a loaʻa ia ma lalo o nā inoa kālepa a me nā lama e like me Crylux, Plexiglas, Acrylite, Perclax, Astariglas, Lucite, a me Perspex, a me nā mea ʻē aʻe. Hoʻohana pinepine ʻia ka Polymethylmethacrylate (PMMA) ma ke ʻano pepa ma ke ʻano he mea māmā a pale paha i ka haki ʻana i ke aniani. Hoʻohana ʻia hoʻi ka PMMA ma ke ʻano he resin hoʻolei, ʻīnika, a me ka uhi ʻana. ʻO ka PMMA kekahi ʻāpana o ka hui mea plastik ʻenekinia.
5. Pehea e hana ʻia ai ka acrylic?
Hana ʻia ka Polymethyl methacrylate ma o ka polymerization ʻoiai ʻo ia kekahi o nā polymers synthetic. ʻO ka mea mua, hoʻokomo ʻia ka methyl methacrylate i loko o ka ʻōmole a hoʻohui ʻia kahi mea hoʻouluulu e wikiwiki i ke kaʻina hana. Ma muli o kēia kaʻina hana polymerization, hiki ke hoʻohālikelike ʻia ka PMMA i nā ʻano like ʻole e like me nā pepa, nā resins, nā poloka, a me nā momi. Hiki i ke kāpili acrylic ke kōkua i ka palupalu ʻana i nā ʻāpana PMMA a hoʻopili pū iā lākou.
He maʻalahi ka hoʻoponopono ʻana i ka PMMA ma nā ʻano like ʻole. Hiki ke hoʻopili ʻia me nā mea ʻē aʻe e kōkua i ka hoʻonui ʻana i kona mau waiwai. Me ka thermoforming, lilo ia i mea palupalu ke hoʻomehana ʻia a paʻa ke hoʻomaʻalili ʻia. Hiki ke hoʻonohonoho pono ʻia ka nui me ka hoʻohana ʻana i ka ʻoki ʻoki laser a i ʻole ka ʻoki ʻana. Inā hoʻopili ʻia, hiki iā ʻoe ke wehe i nā ʻōpala mai ka ʻili a kōkua i ka mālama ʻana i kona kūpaʻa.
6. He aha nā ʻano like ʻole o ka acrylic?
ʻO nā ʻano nui ʻelua o ka plastic acrylic he acrylic i hoʻolei ʻia a me ka acrylic i hoʻokahe ʻia. ʻOi aku ke kumukūʻai o ka hana ʻana i ka acrylic i hoʻolei ʻia akā ʻoi aku ka ikaika, ke kūpaʻa, ka maopopo, ka laulā thermoforming a me ke kūpaʻa ma mua o ka acrylic i hoʻokahe ʻia. Hāʻawi ka acrylic i hoʻolei ʻia i ke kūpaʻa kemika maikaʻi loa a me ke kūpaʻa, a maʻalahi hoʻi ke kala a me ke ʻano i ka wā o ke kaʻina hana. Loaʻa pū ka acrylic i hoʻolei ʻia i nā ʻano mānoanoa like ʻole. ʻOi aku ka waiwai o ka acrylic i hoʻokahe ʻia ma mua o ka acrylic i hoʻolei ʻia a hāʻawi i ka acrylic kūlike a hana ma mua o ka acrylic i hoʻolei ʻia (ma ke kumukūʻai o ka ikaika i hoʻemi ʻia). He maʻalahi ka hana a me ka mīkini ʻana o ka acrylic i hoʻokahe ʻia, e lilo ia i koho maikaʻi loa i nā pepa aniani i nā noi.
7. No ke aha i hoʻohana nui ʻia ai ka acrylic?
Hoʻohana pinepine ʻia ka acrylic no ka mea he like kona ʻano maikaʻi me ke aniani, akā me ka ʻole o nā pilikia brittleness. Loaʻa i ke aniani acrylic nā waiwai optical maikaʻi loa a he like ka refractive index me ke aniani i ke kūlana paʻa. Ma muli o kona mau waiwai shatterproof, hiki i nā mea hoʻolālā ke hoʻohana i nā acrylics ma nā wahi e weliweli loa ai ke aniani a i ʻole e hāʻule paha (e like me nā periscopes submarine, nā puka makani mokulele, a pēlā aku). No ka laʻana, ʻo ke ʻano maʻamau o ke aniani bulletproof he ʻāpana acrylic 1/4-inch-mānoanoa, i kapa ʻia ʻo solid acrylic. Hana maikaʻi nō hoʻi ka acrylic i ka hoʻoheheʻe ʻana i ka injection a hiki ke hana ʻia i loko o kekahi ʻano e hiki ai i ka mea hana mold ke hana. ʻO ka ikaika o ke aniani acrylic i hui pū ʻia me kona maʻalahi o ka hana ʻana a me ka mīkini ʻana e lilo ia i mea maikaʻi loa, e wehewehe ana i ke kumu e hoʻohana nui ʻia ai i nā ʻoihana mea kūʻai aku a me nā ʻoihana kalepa.
