I roto i ngā mara hangahanga teitei pēnei i ngā semiconductors me ngā whatu tika, kua noho ngā turanga tapahi karāneti hei wāhanga matua o ngā taputapu matua nā te mea he tino pumau me te ātete ki te kakahu. Heoi, kua waipuke te mākete i ngā hua rūpahu me ngā hua kino e whakaatu ana i te māpere, te kōhatu horihori me te kōhatu tae, e kore e arahi noa ki te hekenga o te tika o ngā taputapu, engari ka puta hoki he mate nui. Kei roto i tēnei tuhinga he aratohu tautuhi pūtaiao mai i ngā taha e toru: ngā āhuatanga rauemi, ngā tikanga whakamātautau, me ngā pūnaha tiwhikete, hei āwhina i a koe ki te karo i ngā mahanga a ngā kaihoko.
I. Ngā Āhuatanga Rauemi: Te Mātauranga Taketake mō te Tāutu i te Huna
1. Ngā tohu mārō o te mātotoru me te pakeke
Te karāhe tūturu: Ko tōna mātotoru kei waenganui i te 2600 me te 3100kg/m³ (ka taea e ngā karāhe pango kounga teitei pērā i ngā hua ZHHIMG® te eke ki runga ake i te 3000kg/m³), me te pakeke Mohs o te 6 ki te 7. Ina rakurakuhia he moni puta noa i tōna mata, kāore he tohu e toe ana.
Hua rūpahu: Ko te matotoru o te māpere he tata ki te 2500-2700kg/m³, ā, ko tōna pakeke he 3-5 noa iho ngā taumata. Ka waiho he tohu mā te karawarawa māmā ki te moni. Ka tino rerekē te matotoru o te kōhatu horihori, ā, ka puta he tangi ngoikore ina whiua (ko te karāhe tūturu ia ka puta he tangi mārama).
2. Ngā rerekētanga moroiti o te hanganga me te kakano
Karaati tūturu: He mea hanga mai i ngā matūriki kohuke pēnei i te kuata me te feldspar e raranga piri tahi ana. He ira, he rārangi rānei kāore i te ōrite te āhua o tōna kakano, ā, he taratara te tapahi whakawhiti me te āhua kirikiri motuhake.
Kohatu kua taehia: He mangu te āhua o te mata. Tērā pea ka memeha ina murua ki te waipiro, ā, he rerekē rawa te tae o te wāhanga whakawhiti i te tae o te mata. Ko te āhua o te māpere he rārangi tonu, ā, kei roto he tioata konupūmā kāponāte (ka pupuhi ina maturuturuhia te waikawa hauwai waimeha ki runga).
II. Whakamātautau Pūtaiao: Te Whakakite i ngā Kōrero teka mā te Raraunga
1. Whakamātautau mahi taketake
2. Te tautuhi taputapu ngaio
Te kimi hapa ā-orooro: Kāore he haruru hapa e kitea ana i roto i te karāhe tūturu, engari tera pea he ngatata, he whakaata kau rānei o ngā rauemi rūpahu.
Tātaritanga hihi-X: Ka taea te whakatau tika i te hanganga o te kohuke (ko te nuinga o te kirikiri he quartz me te feldspar, ko te mapere he calcite).
III. Pūnaha Tiwhikete: He tiwhikete whai mana mō te karo i ngā tūponotanga
Rārangi o ngā tuhinga me tirotiro
Taunakitanga o te āheinga ki te whai i te uaua o te kōhatu: Mō te kōhatu karāhe tūturu, me whakarato ngā mōhiohio motuhake mō te rua (pēnei i te Shandong Jinan Black, Indian Black).
Pūrongo whakamātautau tuatoru: Kei roto ko ngā raraunga matua pēnei i te mātotoru, te pakeke, me te tauwehenga o te whakawhānui wera (i tukuna e te taiwhanga whaimana CNAS, ISO 17025 rānei);
Tiwhikete Kounga ISO: Me whiwhi ngā kaihanga noa i te tiwhikete pūnaha whakahaere kounga ISO 9001, ā, me whiwhi hoki ngā hua kounga teitei i te tiwhikete taiao ISO 14001.
2. Kia tūpato ki ngā mahanga o ngā pānuitanga teka
Ko ngā hua e kīia ana he "kōhatu whānui" he "mārō tipua" rānei, he mahi tinihanga noa iho.
Me tūpato te hoko i ngā turanga kāore he tawhā hangarau motuhake (pēnei i te papatahi me te tika).
Ko ngā hua he iti iho i te 30% te utu i te toharite o te mākete, tera pea he rūpahu, he iti iho rānei i te paerewa.
