- AS
1. AS hana
ʻO AS he propylene-styrene copolymer, i kapa ʻia ʻo SAN, me ka mānoanoa o kahi o 1.07g/cm3. ʻAʻole maʻalahi i ka haki ʻana i ke kaumaha o loko. He kiʻekiʻe ke aniani, ʻoi aku ke kiʻekiʻe o ka wela palupalu a me ka ikaika o ka hopena ma mua o PS, a ʻoi aku ka maikaʻi o ka luhi luhi.
2. Noi o AS
ʻO nā pā, nā kīʻaha, nā mea pākaukau, nā keʻena friji, nā kī, nā mea kukui, nā mea hoʻonani, nā aniani mea kani, nā pahu pahu, nā mea kākau, nā kukui kinoea, nā lima pulupulu, etc.
3. Nā kūlana hana AS
ʻO ka mahana hana o AS he 210 ~ 250 ℃. He mea maʻalahi kēia mea e hoʻomoʻa i ka makū a pono e hoʻomaloʻo ʻia no hoʻokahi hola ma mua o ka hana ʻana. ʻOi aku ka maikaʻi o ka wai ma mua o PS, no laila ʻoi aku ka kiʻekiʻe o ke kaomi injection, a ʻoi aku ka maikaʻi o ka mahana o ka mold ma 45 ~ 75 ℃.
- ABS
1. ABS hana
ʻO ABS ka acrylonitrile-butadiene-styrene terpolymer. He polymer amorphous me ka nui o ka 1.05g/cm3. Loaʻa iā ia ka ikaika mechanical kiʻekiʻe a me nā waiwai piha maikaʻi o "vertical, paʻakikī a me ke kila". ʻO ka ABS he plastic engineering i hoʻohana nui ʻia me nā ʻano like ʻole a me ka hoʻohana ākea. Ua kapa ʻia ʻo ia ʻo "general engineering plastic" (kapa ʻia ʻo MBS transparent ABS). He maʻalahi ka hana ʻana a me ke kaʻina hana, ʻaʻohe kūpaʻa kemika, a maʻalahi nā huahana i ka electroplated.
2. Ke noi o ABS
Pump impellers, bearings, handles, pipes, electrical appliance casings, electronic product parts, toys, watch cases, instrument cases, water tank casings, cold storage and refrigerator inner casings.
3. ABS kaʻina hana
(1) He kiʻekiʻe ka hygroscopicity o ABS a me ka pale wela maikaʻi ʻole. Pono e hoʻomaloʻo piha ʻia a hoʻomaʻamaʻa mua ʻia ma mua o ka hoʻoheheʻe ʻana a me ka hana ʻana no ka mālama ʻana i ka wai ma lalo o 0.03%.
(2) ʻO ka viscosity hehee o ka resin ABS ʻaʻole i maʻalahi i ka mahana (ʻokoʻa mai nā resins amorphous ʻē aʻe). ʻOiai ʻoi aku ka kiʻekiʻe o ka mahana injection o ABS ma mua o ka PS, ʻaʻole i loaʻa kahi ākea e piʻi ana ka wela e like me PS, a ʻaʻole hiki ke hoʻohana ʻia ka hoʻomehana makapō. No ka ho'ēmiʻana i kona viscosity, hiki iāʻoe ke hoʻonui i ka wikiwiki a iʻole e hoʻonui i ke kaomi injection / ka wikiwiki e hoʻomaikaʻi i kona wai. ʻO ka mahana hana maʻamau he 190 ~ 235 ℃.
(3) ʻO ka melt viscosity o ABS he mea waena, ʻoi aku ka kiʻekiʻe ma mua o ka PS, HIPS, a me AS, a ʻoi aku ka maikaʻi o ka wai, no laila e koi ʻia ke kiʻekiʻe o ke kaomi injection.
(4) He hopena maikaʻi ko ABS me ka wikiwiki o ka hoʻoheheʻe ʻia ʻana (koe ke koi ʻia nā ʻano paʻakikī a me nā ʻāpana lahilahi i ka wikiwiki o ka injection), ʻoi aku ka maikaʻi o ka nozzle o ka huahana i nā kaha ea.
(5) He kiʻekiʻe ke kiʻekiʻe o ka mahana hoʻoheheʻe ʻana o ABS, a ua hoʻoponopono ʻia kona ʻano wela ma waena o 45 a me 80 ° C. I ka hana ʻana i nā huahana ʻoi aku ka nui, ʻoi aku ka nui o ka mahana o ka mold paʻa (mua o mua) ma kahi o 5 ° C kiʻekiʻe ma mua o ka movable movable (hope mold).
(6) ʻAʻole pono ʻo ABS e noho i loko o ka pahu wela wela no ka lōʻihi loa (e emi iho ma mua o 30 mau minuke), i ʻole e pohō a huli melemele.
- PMMA
1. Hana o PMMA
ʻO ka PMMA he polymer amorphous, i ʻike mau ʻia ʻo plexiglass (sub-acrylic), me ka nui o kahi 1.18g/cm3. Loaʻa iā ia ka transparency maikaʻi a me ka transmittance māmā o 92%. He mea optical maikaʻi ia; maikaʻi kona kūpaʻa wela (heat resistance). ʻO ka mahana deformation he 98 ° C). Loaʻa i kāna huahana ka ikaika mechanical a me ka paʻakikī haʻahaʻa. ʻAi maʻalahi ʻia e nā mea paʻakikī a waiho i nā meheu. Ke hoʻohālikelike ʻia me PS, ʻaʻole maʻalahi ka palupalu.
2. Noi o PMMA
ʻO nā lens mea hana, nā huahana optical, nā mea uila, nā mea lapaʻau, nā hiʻohiʻona akaka, nā mea hoʻonani, nā aniani o ka lā, nā niho niho, nā papa hoʻolaha, nā paneli uaki, nā kukui huelo kaʻa, nā pale makani, etc.
3. Kaʻina hana o PMMA
He koʻikoʻi nā koi hana o PMMA. He mea maʻalahi loa ia i ka makū a me ka mahana. Pono e maloʻo loa ma mua o ka hana ʻana. He mea kiʻekiʻe kona melt viscosity, no laila pono e hoʻoheheʻe ʻia ma kahi kiʻekiʻe o ka mahana (219 ~ 240 ℃) a me ke kaomi. ʻOi aku ka maikaʻi o ka mahana ma waena o 65 ~ 80 ℃. ʻAʻole maikaʻi loa ka paʻa wela o PMMA. E hoʻohaʻahaʻa ʻia e ka wela kiʻekiʻe a i ʻole ka noho ʻana ma kahi wela kiʻekiʻe no ka lōʻihi loa. ʻAʻole pono ke kiʻekiʻe loa ka wikiwiki o ka wili (e pili ana i 60rpm), no ka mea he maʻalahi ia i nā ʻāpana PMMA mānoanoa. Pono nā ʻīpuka nui a me ka "mea wela kiʻekiʻe, ka wela kiʻekiʻe, ka wikiwiki lohi" i nā kūlana injection e hana.
4. He aha ka acrylic (PMMA)?
ʻO ka Acrylic (PMMA) he ʻilika māmā a paʻakikī hoʻi i hoʻohana pinepine ʻia ma kahi o ke aniani i nā huahana e like me nā puka makani paʻa ʻole, nā hōʻailona i hoʻomālamalama ʻia, nā kukui a me nā canopies mokulele. No ka PMMA ka ʻohana koʻikoʻi o nā resins acrylic. ʻO ka inoa kemika o ka acrylic he polymethyl methacrylate (PMMA), he resin synthetic polymerized mai ka methyl methacrylate.
Ua ʻike ʻia ʻo Polymethylmethacrylate (PMMA) he acrylic, aniani acrylic, a loaʻa ma lalo o nā inoa kālepa a me nā hōʻailona 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 e like me ke ʻano māmā a i ʻole nā haʻalulu i ke aniani. Hoʻohana ʻia ʻo PMMA ma ke ʻano he resin hoʻolei, inika, a me ka uhi. ʻO ka PMMA kahi ʻāpana o ka hui ʻenehana plastik.
5. Pehea i hana ʻia ai ka acrylic?
Hana ʻia ka polymethyl methacrylate ma o ka polymerization ʻoiai ʻo ia kekahi o nā polymers synthetic. ʻO ka mua, hoʻokomo ʻia ka methyl methacrylate i loko o ka mold a hoʻohui ʻia kahi catalyst 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 lau, resins, poloka, a me nā pahu. Hiki ke hoʻomāmā i nā ʻāpana PMMA a hoʻopaʻa pū iā lākou.
He maʻalahi ka PMMA i nā ʻano like ʻole. Hiki ke hoʻopaʻa ʻia me nā mea ʻē aʻe e kōkua i ka hoʻomaikaʻi ʻana i kāna mau waiwai. Me ka thermoforming, lilo ia i mea maʻalahi ke hoʻomehana ʻia a paʻa i ka wā i hoʻoluʻu ʻia. Hiki ke hoʻohālikelike ʻia me ka hoʻohana ʻana i kahi ʻoki a laser paha. Inā hoʻonaniʻia, hiki iāʻoe ke wehe i nā'ōpala mai kaʻili a kōkua i ka mālamaʻana i kona kūpaʻa.
6. He aha nā ʻano like ʻole o ka acrylic?
ʻO nā ʻano nui ʻelua o ka plastic acrylic he acrylic cast a me extruded acrylic. ʻOi aku ka pipiʻi o ka cast acrylic no ka hana ʻana akā ʻoi aku ka maikaʻi o ka ikaika, ka lōʻihi, ka māmā, ke ʻano thermoforming a me ka paʻa ma mua o ka acrylic extruded. Hāʻawi ka Cast acrylic i ke kūpaʻa kemika maikaʻi a me ka lōʻihi, a maʻalahi ke kala a me ke ʻano i ka wā o ka hana ʻana. Loaʻa ka acrylic cast i nā ʻano mānoanoa. ʻOi aku ka maikaʻi o ka acrylic extruded ma mua o ka acrylic cast a hāʻawi i ka acrylic i ʻoi aku ka paʻa, hiki ke hana ma mua o ka acrylic cast (ma ka lilo o ka ikaika hoʻemi). He maʻalahi ka hana a me ka mīkini extruded acrylic, e hana ia i kahi koho maikaʻi loa i nā lau aniani i nā noi.
7. No ke aha i hoʻohana pinepine ʻia ai ka acrylic?
Hoʻohana pinepine ʻia ʻo Acrylic no ka mea he like nā ʻano pono like me ke aniani, akā me ka ʻole o nā pilikia brittleness. Loaʻa i ka aniani Acrylic nā waiwai optical maikaʻi loa a loaʻa iā ia ka helu refractive like me ke aniani i ke kūlana paʻa. Ma muli o kāna mau waiwai paʻa ʻole, hiki i nā mea hoʻolālā ke hoʻohana i nā acrylics ma nā wahi e weliweli loa ai ke aniani a i ʻole e hāʻule ʻole (e like me nā periscope submarine, nā puka makani mokulele, etc.). No ka laʻana, ʻo ke ʻano maʻamau o ke aniani pōkā he 1/4-iniha ka mānoanoa o ka acrylic, i kapa ʻia ʻo ka acrylic paʻa. Hana maikaʻi nō hoʻi ka Acrylic i ka hoʻoheheʻe ʻia ʻana a hiki ke hana ʻia i kahi ʻano like ʻole e hiki ai i ka mea hana mold ke hana. ʻO ka ikaika o ke aniani acrylic i hui pū ʻia me ka maʻalahi o ka hana ʻana a me ka hana ʻana he mea maikaʻi loa ia, e wehewehe ana i ke kumu e hoʻohana nui ʻia ai i nā ʻoihana kūʻai a me nā ʻoihana.
