ʻO ke koʻikoʻi o ka hoʻopuehu ʻana i ka puaʻa ma ka waihoʻoluʻu plastic

He mea koʻikoʻi ka hoʻopuehu ʻana o nā puaʻa no ke kala ʻana o nā plastics. Ka hopena hope opuaʻaʻAʻole pili wale ka dispersion i ka ikaika o ka puaʻa, akā pili pū kekahi i ke ʻano o ka huahana kala (e like me nā kiko, streaks, gloss, color and transparency), a pili pū kekahi i ka maikaʻi o ka huahana kala, e like me ka ikaika, elongation, kū'ē i ka huahana. ʻO ka ʻelemakule a me ka resistivity, a me nā mea ʻē aʻe, pili pū i ka hana hana a me ka hana noi o nā plastics (me ka waihoʻoluʻumasterbatch).

ʻO ka dispersibility o nā puaʻa i loko o nā plastics e pili ana i ka hiki o nā puaʻa e hōʻemi i ka nui o nā aggregates a me nā agglomerates i kahi nui i makemake ʻia ma hope o ka pulu. Aneane nā waiwai a pau o nā puaʻa i loko o nā noi plastik e pili ana i ke kiʻekiʻe e hiki ke hoʻopuehu maikaʻi ʻia nā puaʻa. No laila, ʻo ka dispersibility o nā puaʻa he hōʻailona koʻikoʻi no ka noi makala ʻulaʻula.

I ke kaʻina hana o ka puaʻa, ua hoʻokumu mua ʻia ka nucleus kristal. ʻO ka ulu ʻana o ka nucleus crystal he aniani hoʻokahi i ka hoʻomaka, akā e ulu koke ia i polycrystal me kahi ʻano mosaic. ʻOiaʻiʻo, ʻoi aku ka maikaʻi o kāna mau ʻāpana, a ʻo ka nui o ka laina o nā ʻāpana ma kahi o 0.1 a 0.5 μm, ka mea i kapa ʻia ʻo nā ʻāpana kumu a i ʻole nā ​​​​palapala mua. Hoʻohui ʻia nā ʻāpana mua, a ua kapa ʻia nā ʻāpana i hoʻohui ʻia he mau ʻāpana lua. Wahi a nā ʻano ʻano hoʻohui like ʻole, ua māhele ʻia nā ʻāpana lua i ʻelua mau ʻāpana: ʻo ka mea hoʻokahi e pili ana nā kristal e nā kihi aniani a i ʻole nā ​​kihi, liʻiliʻi ka huki ʻana ma waena o nā crystals, wehe ʻia nā ʻāpana, a maʻalahi hoʻi e hoʻokaʻawale ʻia. ka hoʻopuehu ʻana, i kapa ʻia he hoʻopili. Huihui; ʻO kekahi ʻano ʻē aʻe, ua hoʻopaʻa ʻia nā kristal e nā mokulele aniani, ikaika ka ikaika hoihoi ma waena o nā kristal, paʻa paʻa nā ʻāpana, i kapa ʻia ʻo aggregates, ʻoi aku ka liʻiliʻi o ka ʻili o nā aggregates ma mua o ka huina o nā ʻāpana ili o ko lākou mau ʻāpana. a ke hilinaʻi nei nā hui i nā kaʻina hoʻopuehu maʻamau. Aneane paakiki ka hoopuehu.
