Utu Hokomaha 2021 Ngā Porowhita Uku - Ngā Pīra Karāhe Whakaata mō ngā Tohu Rori – Kehui

He momo rauemi hou ngā pīrere karāhe i whakawhanakehia i ngā tau tata nei, he whānuitia ngā whakamahinga me ngā āhuatanga motuhake. He mea hanga te hua mai i ngā rauemi mata borosilicate mā te tukatuka hangarau teitei, me te rahi o te matūriki o te 10-250 microns me te matotoru o te pakitara o te 1-2 microns. He māmā te taumaha o te hua, he iti te kawe wera, he kaha teitei, he pai te pumau matū, me ētahi atu. Kua rongoatia tōna mata kia whai āhuatanga lipophilic me hydrophobic, ā, he tino ngāwari ki te horapa i roto i ngā pūnaha rauemi rauropi.
E whakamahia ana ngā piripiri karāhe moroiti hei tango i te waikura o ngā mīhini rererangi, ngā whiti zebra, ngā rārangi kore-mutu, ngā rārangi kōwhai takirua i ngā whakaata pō i runga i ngā rori waka o te tāone, me ngā taputapu whakaata pō mō ngā tohu waka.

Taupū matū
1. Te hanganga matū:
SiO2 >67%, CaO >8.0% MgO >2.5%, Na2O0.15, ētahi atu 2.0%.
2. Taumaha motuhake: 2.4-2.6g/cm³.
Āhua: karāhe maeneene, porowhita, mārama, kāore he poke
Te tere whakaawhiwhi: ≥85% neke atu rānei.
3. Kaua ngā matūriki aukume e neke ake i te 0.1% o te taumaha o te hua.
4. He iti iho i te 10% te nui o te mirumiru i roto i ngā pirepire karāhe.
5. Kāore he wāhanga o te kapia silicone.
6. Te mātotoru o te papatipu: 1.5g/cm³
7. Te pakeketanga o Mohs: 6-7
8. Te pakeke o Rockwell: 48-52HRC

He whānuitia ngā whakamahinga me ngā āhuatanga motuhake o ngā pīrere karāhe. He iti noa te whānui, he māmā, he kaha hoki. Mā te tāpiri atu ki ngā paninga ka taea te hanga paninga whakaata e hiahiatia ana e te tangata. He kaha te mahi whakaata-muri, ā, i te nuinga o te wā, ka taea te whakaata tika i te mārama ki te pūtake mārama, nō reira ka puta he pānga whakaata-muri kaha. Nā te whakamahinga o ngā pīrere karāhe whakaata kua tino pai ake te mahi haumaru rori.

Kāore e hiahiatia he hiko mō te peita i tāpirihia ki ngā pīrere karāhe whakaata rori, ā, ka taea hoki te whakaoti i te mahi whakamahara o ngā tohu pō. Nō reira, ka whakamahia ngā pīrere karāhe whakaata rori i roto i ngā tohu huarahi, i ngā whare o waho, i ngā tohu rori me ētahi atu whakatūpato pō. Nā te maha o ngā tohu kua tino pai ake te mōhio ki ēnei tohu i te pō, he tino pai te mahi hei ārahi me te whakatūpato, ā, kua whakarato i tētahi raina haumaru kaha ake mō ngā taraiwa e taraiwa ana i te pō.

Ngā painga o ngā pīrere karāhe whakaata rori:

Ka tāpirihia tika te rauemi karāhe whakaata-iti ki te kāpū wai, kātahi ka whakatikatikahia kia ōrite. Mena e tika ana, ka taea te tāpiri i tētahi nui o ngā tāpiringa hei whakapakari i tōna pakari, kātahi ka taea te whakamahi tika. Tāpirihia tika ki te paraoa mārama, whakaohokia kia ōrite, ka tāpirihia he nui o ngā tāpiringa kia rite ki ngā hiahia tūturu kia pai ake ai te pānga o te tono.

Ka taea te tāpiri tika i ngā poroporo karāhe whakaata rori ki te waituhi hei hanga waituhi whakaata, ka taea te tā mata, te peita rānei ki runga i ngā kakahu, ki ētahi atu taonga rānei. He tino māmā, he watea hoki te whakamahi, ā, he ngāwari hoki te ako. Me mōhio ko te nui o ngā poroporo karāhe whakaata e tāpirihia ana ka taea te tāpiri tika i runga i te nui o te whakaata e hiahiatia ana.

Rehuhia te turanga whakaata i te tuatahi, kātahi ka tatari kia maroke te turanga whakaata i mua i te rehu i te paninga whakaata. Mena kua hangaia te mata sima, he pai ake te rehu i ngā paparanga e rua. I te wa e rehu ana, me whakamahi i te hinu ngaio. I te wa e rehu ana, ngana ki te whakamahi i tetahi waahi iti i mua, kia aro ki nga ahuatanga o te rangi o te hanganga, kaua e hanga i te rangi ua, kia kore ai e kore e taea e nga piripiri karaihe whakaata te mahi katoa.
