UL94 V0, V2 a me 5VA mau helu a ua hoʻokō ʻo RoHS.A ʻo kahi papa kumu nui i hoʻoikaika ʻole ʻia e hāʻawi ana i ke kūpaʻa wela kiʻekiʻe, ka ikaika kiʻekiʻe a me ka modulus a me ka pale kemika ākea a hiki i nā wela kiʻekiʻe. |
ʻenehana
ʻO nā ʻano o nā mea i hoʻohana pinepine ʻia ma ka mākeke: polymethyl methacrylate (acrylic or plexiglass PMMA plastic), polycarbonate (PC plastic), polyethylene terephthalate (PET), transparent nylon, AS (Acrylonitrile-styrene copolymer) etc. I waena o lākou, ʻO nā plastics ʻekolu i ʻike nui ʻia iā mākou ʻo PMMA, PC a me AS.
1. ʻO nā waiwai o nā plastic transparent: ʻo ka mea mua, pono e loaʻa i nā plastic transparent kiʻekiʻe, a ʻo ka lua, pono lākou e loaʻa kekahi ikaika a me ke kūpaʻa ʻana, ka hopena hopena, ka pale wela, ke kūpaʻa kemika, a me ka lawe ʻana i ka wai.I ka hoʻohana ʻana, hoʻokō ʻo ia i nā koi o ke aniani a loaʻa ka hana paʻa.
2. Kaʻina hana o PMMA.He kiʻekiʻe ka viscosity a me ka wai maikaʻi ʻole o ka PMMA.No laila, pono e hoʻohana ʻia ke kiʻekiʻe o ka mea wela a me ke kiʻekiʻe kiʻekiʻe no ka hoʻoheheʻe ʻana.ʻOi aku ka mana o ka wela o ka injection ma mua o ke kaomi ʻana, akā ʻo ka piʻi ʻana o ke kaomi injection e kōkua i ka hoʻomaikaʻi ʻana i ka helu shrinkage o ka huahana.ʻAʻole maikaʻi ka hopena maikaʻi ʻole, maikaʻi ʻole ke kāʻei ʻana, maʻalahi i ka ʻōpala, maʻalahi i ka brittle, no laila e hoʻonui ʻia ka mahana o ka mold, a pono e hoʻomaikaʻi ʻia ke kaʻina condensation e lanakila ai i kēia mau hemahema.
3. Kaʻina hana o PC.PC i kiʻekiʻe viscosity, kiʻekiʻe melting wela a me ka ilihune fluidity, a me kona manufacturability 'aʻole maikaʻi e like me PMMA.He liʻiliʻi ka hopena o ke kaomi injection i ka wai, akā ma muli o ka viscosity kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ke kaomi injection.E like me ia, i mea e pale aku ai i ke koʻikoʻi o loko, pono e pōkole ka manawa paʻa i ka hiki.Nui ka shrinkage rate, paʻa ka nui, akā nui ke koʻikoʻi o loko o ka huahana, a maʻalahi ke haki.
4. Kaʻina hana o PET.He kiʻekiʻe ka mahana o ka hoʻoheheʻe ʻana o PET, a he haiki (260-300 ° C), akā ma hope o ka hoʻoheheʻe ʻana, loaʻa ka wai maikaʻi, no laila ʻilihune ka hana ʻana, a pono pinepine e hoʻohui i nā mea hoʻolaha anti-spreading. nozzle.ʻAʻole kiʻekiʻe ka ikaika mechanical a me ka hana ma hope o ka injection, a pono e hoʻomaikaʻi ʻia ka hana ma o ke kaʻina hana a me ka hoʻololi.
