ʻOiai he nui nā waiwai maikaʻi o ka plastic, ʻaʻole hiki i kēlā me kēia ʻano plastik ke loaʻa nā waiwai maikaʻi a pau.Pono nā mea ʻenekinia waiwai a me nā mea hoʻolālā ʻenehana e hoʻomaopopo i nā waiwai o nā plastik like ʻole i mea e hoʻolālā ai i nā huahana plastik kūpono.ʻO ka waiwai o ka plastic, hiki ke hoʻokaʻawale ʻia i ka waiwai kino kumu, ka waiwai mechanical, ka waiwai wela, ka waiwai kemika, ka waiwai optical a me ka waiwai uila, a me nā mea ʻē aʻe.ʻO lākou nā plastics me ka ikaika maikaʻi loa, ka pale ʻana i ka hopena, ka pale wela, ka paʻakikī a me nā waiwai anti-aging.E wehewehe ka ʻoihana Iapana iā ia ma ke ʻano he "hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana a me nā ʻāpana mīkini o nā plastics hana kiʻekiʻe, pale wela ma luna o 100 ℃, hoʻohana nui ʻia i ka ʻoihana".
Ma lalo mākou e papa inoa i kekahi mau mea maʻamaumea hoao:
1.Helu Hehe(MFI):
Hoʻohana ʻia no ke ana ʻana i ka waiwai MFR melt flow rate o nā plastik like ʻole a me nā resins i loko o ke kūlana kahe viscous.He kūpono ia no nā plastics ʻenekinia e like me polycarbonate, polyarylsulfone, fluorine plastics, nylon a pēlā aku me ka wela hoʻoheheʻe kiʻekiʻe.He kūpono hoʻi no ka polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyformaldehyde (POM), polycarbonate (PC) resin a me nā mea hoʻoheheʻe plastik ʻē aʻe he haʻahaʻa haʻahaʻa.Hoʻokō i nā kūlana: ISO 1133, ASTM D1238, GB/T3682
ʻO ke ʻano o ka hoʻāʻo ʻana e hoʻoheheʻe i nā ʻāpana palaka i loko o ka wai plastik i loko o kekahi manawa (10 mau minuke), ma lalo o kahi mahana a me ke kaomi (nā kūlana like ʻole no nā mea like ʻole), a laila kahe i waho ma kahi anawaena 2.095mm o ka helu o nā kala. (g).ʻOi aku ka nui o ka waiwai, ʻoi aku ka maikaʻi o ka hoʻoili ʻana i ka wai o ka mea plastic, a me ka hope.ʻO ka maʻamau hoʻāʻo maʻamau i hoʻohana ʻia ʻo ASTM D 1238. ʻO ka mea ana no kēia maʻamau hoʻāʻo ʻo Melt Indexer.ʻO ke kaʻina hana kikoʻī o ka hoʻāʻo ʻana: ʻo ka polymer (plastic) mea e hoʻāʻo ʻia e waiho ʻia i loko o kahi ʻāpana liʻiliʻi, a ua pili ka hopena o ke awāwa me kahi paipu lahilahi, ʻo ke anawaena o ia mea he 2.095mm, a me ka lōʻihi o 8mm ka paipu.Ma hope o ka hoʻomehana ʻana i kahi mahana, ʻoki ʻia ka hopena o luna o ka mea maka i lalo e kekahi paona i hoʻohana ʻia e ka piston, a ana ʻia ke kaumaha o ka mea maka i loko o 10 mau minuke, ʻo ia ka helu kahe o ka plastic.I kekahi manawa e ʻike ʻoe i ka hōʻike MI25g/10min, ʻo ia hoʻi ua hoʻopau ʻia ka 25 grams o ka plastic i loko o 10 mau minuke.ʻO ke kumukūʻai MI o nā plastic i hoʻohana mau ʻia ma waena o 1 a me 25. ʻO ka nui o ka MI, ʻoi aku ka liʻiliʻi o ka viscosity o ka mea palaka a me ka liʻiliʻi o ke kaumaha mole;a i ʻole, ʻoi aku ka nui o ka viscosity o ka plastic a ʻoi aku ka nui o ke kaumaha mole.
2. Universal Tensile Testing Machine (UTM)
ʻO ka mīkini hoʻāʻo ʻenehana honua (mīkini tensile): hoʻāʻo i ka tensile, haehae, kulou a me nā mea hana ʻē aʻe o nā mea plastik.
Hiki ke hoʻokaʻawale ʻia i nā ʻāpana:
1)Ka ikaika tensile&ʻO ka lōʻihi:
ʻO ka ikaika tensile, i kapa ʻia ʻo ka ikaika tensile, e pili ana i ka nui o ka ikaika e koi ʻia e hoʻolōʻihi i nā mea plastik i kekahi ʻano, e hōʻike pinepine ʻia i ka nui o ka ikaika o kēlā me kēia ʻāpana, a ʻo ka pākēneka o ka lōʻihi o ka lōʻihi ka elongation.Ka ikaika tensile ʻO ka wikiwiki tensile o ka specimen he 5.0 ~ 6.5mm / min.ʻO ke ala hoʻāʻo kikoʻī e like me ASTM D638.
2)Ka ikaika lohi&Ka ikaika kulou:
ʻO ka ikaika kulou, i ʻike ʻia ʻo ka ikaika flexural, hoʻohana nui ʻia e hoʻoholo i ke kūpaʻa flexural o nā plastics.Hiki ke hoʻāʻo ʻia e like me ke ʻano ASTMD790 a hōʻike pinepine ʻia i nā ʻōlelo o ka nui o ka ikaika o kēlā me kēia wahi.ʻO nā plastik maʻamau i PVC, Melamine resin, epoxy resin a me ka polyester bending ikaika ka mea maikaʻi loa.Hoʻohana ʻia ʻo Fiberglass e hoʻomaikaʻi i ka pale ʻana o nā plastics.ʻO ka elasticity bending e pili ana i ke koʻikoʻi kulou i hana ʻia i kēlā me kēia ʻāpana o ka deformation ma ka pae elastic i ka wā e piʻo ai ka mea hoʻohālike (ʻano hoʻāʻo e like me ka ikaika kulou).Ma keʻano laulā, ʻoi aku ka nui o ka elasticity bending, ʻoi aku ka maikaʻi o ka rigidity o ka mea plastic.
3)Ka ikaika compressive:
ʻO ka ikaika hoʻoemi e pili ana i ka hiki o nā plastics ke kū i ka ikaika hoʻoemi waho.Hiki ke hoʻoholo ʻia ka waiwai hōʻike e like me ke ʻano ASTMD695.ʻO ka polyacetal, polyester, acrylic, urethral resins a me meramin resins he mau waiwai koʻikoʻi ma kēia ʻano.
3.Mīkini hoʻāʻo hopena cantilever/ Simply i kākoʻo ʻia i ka mīkini hoʻāʻo hopena
Hoʻohana ʻia no ka hoʻāʻo ʻana i ka paʻakikī o nā mea non-metallic e like me ka pepa paʻa paʻa, paipu, mea hana kūikawā, hoʻoikaika ʻia ka nylon, aniani fiber reinforced plastic, ceramic, hoʻolei ʻia i nā mea uila uila, etc.
E like me ke kūlana honua ISO180-1992 "plastic - hard material cantilever impact strength determination";ʻO ka pae aupuni GB/ T1843-1996 "paʻakikī paʻakikī cantilever hopena hopena hoʻokolohua", ka mīkini hana maʻamau JB/ T8761-1998 "plastic cantilever hopena hoʻokolohua mīkini".
Nā ho'āʻo 4.Environmental: hoʻohālike i ke kū'ē i ka wā o nā mea.
1) ʻO ka incubator wela mau, ka mīkini hoʻāʻo ʻana i ka mahana a me ka haʻahaʻa haʻahaʻa he mau mea uila, aerospace, automotive, home appliances, pena, ʻoihana kemika, noiʻi ʻepekema i nā wahi e like me ke kūpaʻa o ka mahana a me ka haʻahaʻa hoʻāʻo pono pono, pono no nā ʻāpana ʻoihana, nā ʻāpana mua, nā huahana semi-finished, uila, uila a me nā huahana ʻē aʻe, nā ʻāpana a me nā mea no ka wela kiʻekiʻe, ka haʻahaʻa haʻahaʻa, ke anu, ka wai a me ka wela a i ʻole ka hoʻāʻo mau ʻana o ka hoʻāʻo ʻana i ka mahana a me ka haʻahaʻa.
2) Ka pahu ho'āʻo elemakule pololei, pahu ho'āʻo UV kahiko (ke kukui ultraviolet), pahu ho'āʻo wela kiʻekiʻe a haʻahaʻa,
3) Hōʻike Hōʻikeʻike Thermal Shock Programmable
4) ʻO ke anuanu a me ka wela wela ka mīkini hoʻāʻo ʻana i nā mea uila a me nā mea uila, mokulele, automotive, nā mea hana hale, nā uhi, ʻoihana kemika, ʻoihana pale aupuni, ʻoihana koa, noiʻi ʻepekema a me nā kahua ʻē aʻe e pono ai nā mea hoʻāʻo, He kūpono ia no nā loli kino o ʻāpana a me nā mea waiwai o nā huahana ʻē aʻe e like me ka photoelectric, semiconductor, nā ʻāpana e pili ana i ka uila, nā ʻāpana kaʻa a me nā ʻoihana pili kamepiula e hoʻāʻo i ke kūpaʻa mau ʻana o nā mea i ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa a me nā loli kemika a i ʻole ka pōʻino kino o nā huahana i ka wā e hoʻonui ai ka wela a me ka hoʻohaʻahaʻa anu. .
