Hana ʻia no ka hoʻomanawanui: pehea ka haʻahaʻa haʻahaʻa o ka wai e hōʻoiaʻiʻo ai i ka paʻa ʻana o nā paepae Granite pololei.

ʻO ka pono no ke kūpaʻa dimensional i ke ana pololei loa. ʻOiai e hoʻomaikaʻi ʻia ka granite no kona kūpaʻa wela a me ka hoʻoheheʻe ʻana i ka haʻalulu, ua kū mai kahi nīnau maʻamau mai nā mea ʻenekinia i ka piʻi ʻana o ka ʻāina: Pehea ka hopena o ka makū i kahi paepae pōhaku pololei?

He manaʻo kūpono ia, ʻoiai ʻo nā mea i hoʻohana ʻia ma ke ʻano he mokulele kuhikuhi no nā micrometers a i ʻole CMMs pono e pale i ka hopena o ke kaiapuni. ʻO ka pane pōkole: ma muli o ka mea i koho pono ʻia a me ka hana ʻana, ʻoi aku ka maikaʻi o ka granite precision kiʻekiʻe i ka hopena o ka wai.

ʻO ke kuleana o ka haʻahaʻa wai haʻahaʻa ma Metrology

ʻO Granite, ma ke ʻano he pōhaku maoli, loaʻa kekahi pae o ka porosity. Eia nō naʻe, koho pololei ʻia nā ʻano kikoʻī o ka granite ʻeleʻele i hoʻohana ʻia e ZHHIMG no nā noi metrology no ko lākou ʻano paʻa a me ka maikaʻi, ka mea e alakaʻi ai i ka liʻiliʻi o ka lawe ʻana i ka wai.

Hōʻike maʻamau ka granite metrology-grade maʻamau i ka nui o ka absorption o ka wai ma lalo o 0.13% (ʻoi aku ka haʻahaʻa o nā ʻano premium, kokoke pinepine i ka 0.07% a i ʻole ka liʻiliʻi). He mea koʻikoʻi kēia ʻano no ka mālama ʻana i ka pololei i ka wā lōʻihi:

• Hoʻemi i ka Hoʻonui Hygroscopic: ʻOiai hiki ke pehu a ʻaelike paha kekahi mau mea i ko lākou komo ʻana a hoʻokuʻu paha i ka makū (hygroscopic expansion), ʻo ka porosity haʻahaʻa loa o ka granite precision e kaupalena nui i kēia hopena. He mea ʻole ka nui o ka wai i hoʻomoʻa ʻia e ka pōhaku, e pale ana i kekahi hoʻololi nui nui e hiki ke hoʻopilikia i ka palahalaha o ka mokulele.
• Palekana i ka Rust: Malia paha ʻoi aku ka maikaʻi o ka hoʻomaʻamaʻa ʻana i ka pale i hāʻawi ʻia i kāu mau mea hana waiwai. Inā loaʻa ka porosity kiʻekiʻe o ka pā ili, e mau ana ka makū ma kahi kokoke i ka ʻili. Hiki i kēia wai ke kumu i ka ʻino a me ka ʻōpala ma nā ana metala, nā mea pono, a me nā ʻāpana i kau ʻia ma luna o ka granite, e alakaʻi ana i ka ʻaʻahu mua a me nā ana haumia. ʻO ka porosity haʻahaʻa o kā mākou Black Granite Components e hōʻemi i kēia pilikia, e kākoʻo ana i kahi kaiapuni ʻole.

ʻO ka haʻahaʻa a me ka pololei: ka hoʻomaopopo ʻana i ka hoʻoweliweli maoli

ʻOiai ʻo ka granite ponoʻī e kūʻē i ka deformation dimensional mai ka haʻahaʻa o ka lewa, pono mākou e wehewehe i ka ʻokoʻa ma waena o ka paʻa o ka mea a me ka hoʻomalu ʻana i ke kaiapuni i loko o kahi keʻena kikoʻī.

Ma ke ʻano he poʻe loea i ka Ultra-Precision Platforms, manaʻo mākou e mālama nā mea kūʻai aku i kahi kaiapuni i mālama ʻia i ka haʻahaʻa, kūpono ma waena o 50% a me 60% Relative Humidity (RH). He mea liʻiliʻi kēia mana e pili ana i ka pale ʻana i ka papa pōhaku a ʻoi aku e pili ana i ka mālama ʻana i ka ʻōnaehana metrology holoʻokoʻa (CMMs, gauges, optics) a me ka hōʻoia ʻana i ka paʻa wela o ka ea ponoʻī.

ʻO ka hōʻoiaʻiʻo o ZHHIMG no ka paʻa mau

ʻO ka granite a mākou e koho ai—kaulana no kona ʻano nui a me ka palaoa maikaʻi—hāʻawi i kahi kahua paʻa paʻa e kūʻē i nā loli wela a me ka makū. ʻO kā mākou kūpaʻa i ka hoʻohana ʻana i ka granite me ka ʻumekaumaha kikoʻī kiʻekiʻe e hōʻoiaʻiʻo e loaʻa iā ʻoe kahi papa nānā ʻana i ka corrosion-resistant e mālama ai i kona palahalaha a me kona kūpaʻa no nā makahiki he nui, e koi ana i ka hoʻoponopono hou ʻana i ka ʻoihana maʻamau ma muli o ka ʻaʻahu, ʻaʻole ka deformation kaiapuni.

Ke hoʻokomo nei ʻoe i kahi waihona ZHHIMG Precision Granite, ke hoʻopukapuka nei ʻoe i kahi kahua i hana ʻia no nā ʻano koʻikoʻi o ke ana ʻana i ke ana ʻana kiʻekiʻe.
