Pauka Wollastonite Kina no nā mea kūkulu hale hana keramika uhi ʻoihana hana metallurgical hale hana a me nā mea hoʻolako

Pauka Wollastonite no nā mea kūkulu hale nā huahana seramika ʻoihana uhi hana metallurgical Kiʻi i hōʻike ʻia

Pauka Wollastonite no nā mea kūkulu hale, nā huahana seramika, ka ʻoihana uhi ʻana, ka hana ʻana i nā mea hao

Wehewehe Pōkole:

ʻO ka pauka Wollastonite, kahi mineral versatile i haku ʻia me ka calcium metasilicate, loaʻa nā noi nui ma nā ʻoihana like ʻole ma muli o kona mau waiwai kino a me ke kemika kū hoʻokahi. I ka ʻoihana keramika, lawelawe ia ma ke ʻano he mea hoʻololi pāʻani. No ka laʻana, hoʻohui pinepine nā mea hana tile i ka 10-15% pauka wollastonite i kā lākou mau ʻano. Hoʻemi nui kēia hoʻohui i ka helu shrinkage i ka wā o ke ahi ʻana a hiki i ka 30%, e hoʻemi ana i ka hanana o nā māwae a me nā deformations. ʻO ka hopena, piʻi ka hua hana, a hōʻike nā tile i ka paʻakikī i hoʻonui ʻia a me ke kū'ē ʻana i ke kahakaha, e kūpono ai lākou no nā wahi kaʻa nui e like me nā hale kūʻai kūʻai a me nā kahua mokulele.

I ka hana ʻana i nā plastik, hana ka pauka wollastonite ma ke ʻano he mea hoʻopihapiha hoʻoikaika maikaʻi loa. Ua hoʻohui kahi mea hoʻolako ʻāpana kaʻa alakaʻi i ka 25% pauka wollastonite i ka polypropylene e hana i nā ʻāpana puka māmā. ʻAʻole i hoʻomaikaʻi wale ka mea i hoʻololi ʻia i ka ikaika hopena ma ka 40% akā ua hōʻemi pū i ka warpage, e hōʻoia ana i kahi kūpono kūpono i ka wā o ka ʻākoakoa. Ua kōkua kēia hana hou i ka hui e hōʻemi i nā kumukūʻai hana ma ka 18% me ka hoʻokō ʻana i nā kūlana palekana kaʻa paʻa.

Loaʻa pū ka pōmaikaʻi nui i ka ʻāpana pena a me ka uhi ʻana mai ka pauka wollastonite. Ke hoʻohui ʻia i loko o nā pena o waho, hana kona ʻano kristal acicular i kahi pale e kūʻē i ka wai a me ka radiation UV. Ua hōʻike ʻia kahi hihia noiʻi ua mālama nā hale i uhi ʻia me nā pena i loaʻa he 12% pauka wollastonite i 80% o ko lākou kala mua ma hope o ʻekolu mau makahiki, hoʻohālikelike ʻia me 60% wale nō no nā pena maʻamau.

Wollastonite

Nā kikoʻī:

He mineral silicate kaulahao hoʻokahi ʻo Wollastonite, ʻo ka ʻāpana nui ʻo Ca₃Si₃O₉ʻŌnaehana kristal Triclinic, ma ke ʻano maʻamau o nā flakes, radial a i ʻole fibrous aggregates. Keʻokeʻo me ka hina iki. ʻĀlohilohi aniani, ʻālohilohi momi ma ka ʻili cleavage. Paʻakikī 4.5-5.0 me ka density o 2.78-2.91g/cm³ʻO ia ka mea nui i hana ʻia ma ka ʻāpana metamorphic pili o ka pōhaku intrusive acidic a me ka limestone, ʻo ia ka mea nui o ka mineral skarn.

Ka Pōmaikaʻi o ka Huahana:

ʻOihana palakiko:

I loko o ka ʻoihana palakiko, ʻaʻole wale ka pauka wollastonite e hoʻopiha, akā hoʻololi hapa pū kekahi i ka asbestos a me ke aniani fiber no nā mea hoʻoikaika. Hoʻohana nui ʻia e hoʻomaikaʻi i ka ikaika tensile a me ka ikaika flexural a hoʻemi i nā kumukūʻai.

ʻOihana laholio:

I loko o ka ʻoihana laholio, ʻo ka pauka wollastonite kahi mea hoʻopihapiha kūpono no ka laholio, ʻaʻole hiki ke hōʻemi wale i ke kumukūʻai hana o nā huahana laholio, akā hiki ke hoʻomaikaʻi i nā waiwai mechanical laholio e hāʻawi i nā hana kūikawā i loaʻa ʻole i ka laholio.

ʻOihana Pena a me nā Uhi:

I ka ʻoihana uhi ʻana, hoʻohana ʻia ka pauka wollastonite ma ke ʻano he mea hoʻopihapiha no nā pena a me nā uhi ʻana, hiki ke hoʻomaikaʻi i nā waiwai kino a me nā kemika o ka huahana, ka lōʻihi a me ke kūpaʻa i ka wā, hoʻemi i ka ʻōlinolino o ka pena, hoʻonui i ka hiki ke hoʻonui i ka uhi ʻana, hoʻemi i nā māwae, a hiki ke hoʻemi i ka omo ʻana o ka aila a hoʻonui i ke kūpaʻa ʻana i ka corrosion.
