Te Tino Whai Hua o te Paura Ma o te Kōrunuma Ma i roto i te Whakakanapa Kōhatu
Ki te pono, ina tae ki te "whakakanapa kōhatu," ko te whakaaro tuatahi o te tini tāngata ko ngā mīhini nui, ngā wheketere haruru, me ngā kōpae huri i roto i ngā ringa o ngā kaiwhakakanapa mohio. Engari ki te tino mārama koe ki te umanga, ka kitea e koe ko ngā paura iti e kore e kitea te nuinga o te wā e whakatau ana i ngā hua whakamutunga. Hei tauira, ko tepaura moroiti kōrunuma māKo tā tātou e kōrero nei i tēnei rā ko tēnei "rangatira o te whakakanapa" e huna ana i muri i ngā whakaaturanga. I taku tīmatanga ki te mahi i tēnei mara, i pōhēhē anō hoki ahau: Ehara i te mea he kōhatu whakakanapa noa iho? Kāore he aha te "paura". Engari i muri i taku kitenga atu i ētahi atu, ka kite ahau ka taea e te whiriwhiri i te paura iti tika te hanga i tētahi rerekētanga nui ki ngā hua.
1. He aha te paura iti o te kōrundum mā? He aha i pai ai mō te whakakanapa?
Ki te kī māmā, he mea hanga e te tangata te kōrundum mā, he mea tino parakorewaikura konumohe (Al₂O₃)He mārō ake i te kōrundum tūturu, ko te pakeketanga Mohs he 9.0, ko te tuarua anake ki te taimana me te silicon carbide. E ai ki te ingoa, ko te "micropaur" e pā ana ki te rauemi kua kuruhia, kua tātarihia kia rite ki te paura pai o te taumata micron. Tērā pea ka pātai koe: "E kore e rakurakuhia e tēnei rauemi te kōhatu?" Nā tēnei ka kitea ōna painga: he mārō teitei engari he tino pakari: he ātete ngā matūriki kōrundum mā ki te pakaru, ka mau tonu te kaha tapahi ōrite i te wā e whakakanapahia ana; he pumau matū: kāore e tauhohe ki ngā kohuke i roto i te kōhatu, kāore e puta he tae, he waikura rānei; ā, he tino taea te whakahaere i te rahi o te matūriki: he ratonga whānui tā rātou e tuku ana mai i te huri taratara ki te whakakanapa pai, he mea tino pai mō ngā tukanga whakakanapa maha-wāhanga. Nā ēnei āhuatanga e tino pai ai mō te tukatuka i ngā kōhatu whakapaipai noa pēnei i te māpere, te karāneti, me te kōhatu horihori.
II. He aha rawa te mea e "tino whai hua" ai i roto i te whakakanapa?
He tokomaha e whakaaro ana ko te whakakanapa he mea noa iho kia kanapa te mata o te kōhatu, engari ehara i te mea pēnā. Me tere te tango i ngā karawarawa i roto i te tukanga whakakanapa pai, me te whakapai haere i te kanapa, me te karo hoki i te whakakanapa nui rawa, i te kino rānei o te kakano.
1. Te oro matotoru, te oro waenga, me te oro pai, kua oti pai te oro
Hei tauira, ina mahi ana me ngā papa māpere:
Whakakanapa taratara (80#-200#): Whakamahia he mea whakakanapa taratarapaura kōrunuma mā(pērā i te W40-W20) hei whakangawari tere i te mata, hei tango hoki i ngā karawarawa hōhonu;
Whakakanapa waenga (400#-800#): Whakawhiti ki te paura angiangi (pērā i te W14-W7) mō te whakakanapa tuatahi;
Te whakakanapa pai (1500#-3000#): Ahakoa ngā paura he W3.5, iti iho rānei, ka taea te whakamahi hei whakatutuki i te āhua whakaata.
Ka kitea e koe ka taea te whakamahi i ngā paura o te rauemi kotahi, i roto i ngā rahi matūriki rerekē, puta noa i te tukanga whakakanapa katoa, ā, ka kore e hiahiatia he whakawhiti rauemi auau—ka penapena i te wā, te kaha, me ngā hapa.
2. He piri kaha me te oro tere
Ki te whakatauritea ki ngā rauemi tuku iho pērā i te oneone diatomaceous me te cerium oxide, he māmā ake te mimiti o te paura korundum mā ki te mata o te kōhatu, me ōna matūriki koi (kaua ki te porowhita), ā, ka nui ake te pai o te tapahi. Kua whakahaerehia e mātou he whakataurite: mā te whakakanapa i te wahi kotahi o te karāhe ki te paura moroiti korundum mā ka taea te whakatutuki i te kanapa ōrite i roto i te 1/3 o te wā poto atu i te whakakanapa ki ngā rauemi noa.
3. Kāore e whiriwhiria rawatia ngā rauemi kōhatu, he maha ngā whakamahinga
Korunuma māHe mea noa iho, ahakoa he māpere waikawa nui, he karāneti rānei he nui te hiraka. He pono rawa tēnei mō ngā kōhatu horihori whakauru (pērā i te kuata), kei roto nei ngā rauemi kapia me ngā rauemi kohuke. He maha ngā mea whakakoi tuku iho ka taea te whakapōturi, te whakakorikori rānei, engari he koi tonu te kōrunuma mā.
4. He roa te ora, he iti ake te utu katoa
Ahakoa he iti ake te utu o te paura iti korundum mā mō ia waeine i ētahi rauemi tuku iho, he ātete ki te kakahu, he ātete ki te memeha, ā, he tere te whakamahi anō. He maha ngā wā, ka taea e te puranga rauemi te kapi i te 20%-30% te horahanga mata nui ake, ā, he pai ake te utu mō te wā roa.
Ⅲ. He tauira tūturu kei reira? He tino whai hua rānei?
Me hoatu e au he tauira whaiaro ki a koe: I te tau kua hipa, i whakahoutia te tomokanga o te hōtēra. I kapi te papa māpere parauri i ngā karawarawa nā ngā tau maha o te whakamahinga, ā, he iti iho i te 30 te kanapa. I te tīmatanga i whakamahia e te tīma hanga he paura whakakanapa noa, engari i muri i ngā paninga e toru, kāore tonu i te pai ngā hua. Kātahi ka huri rātou ki te whakapiri whakakanapa i hangaia ki te paura iti korundum mā. I muri i ngā paninga e rua noa iho, i eke rātou ki te taumata kanapa neke atu i te 75 nekehanga. Ko te taumata kanapa whakamutunga i te tukunga tata ki te 85. I whakahoutia tonutia e te kiritaki te kirimana. I kī te tohunga toi i tētahi mea tino ngākau nui: "He rite tēnei ki te whiwhi patu hou i roto i tētahi kēmu—ka tere te patu i ngā taniwha, ā, kāore he utu hauora mōu."
IV. Ngā Auahatanga Whanaketanga ā-Mārama? Ka Whakakapia rānei?
I tēnei wā, kei te mau tonu te tūranga pakari o te paura kōrunamu mā i roto i te whakakanapa kōhatu, engari kei te whanake haere tonu hoki:
Rahi matūriki angiangi ake, angiangi ake: Kua tīmata te whakamahi i te paura korundum mā nano-grade (hei tauira, W1.0 me raro iho) mō te whakakanapa whakaata-tino, inā koa i roto i ngā whakapaipai teitei me te tukatuka kōhatu toi;
Ngā whakamahinga whakakotahi: Hei tauira, ina konatunatua ki te cerium oxide me te paura taimana, ka tutuki he kaha tapahi taurite me te kanapa, he pai mō ngā rauemi kōhatu motuhake;
Te tiakitanga me te haumaru taiao kua whakarei ake: Kei te whakakapia haeretia ngā paura maroke tawhito e tētahi whakatupuranga hou o ngā para whakakanapa wai, e whakaiti ana i te parahanga puehu, ā, e pai ake ai mō te miihini aunoa;
Whakatau: Ngā Rauemi Iti, Pānga Nui
He maha ngā wā ka arotahi tātou ki ngā mea e kitea whānuitia ana—pērā i te waitohu o te mīhini whakakanapa, i te ingoa rongonui rānei o te tīma hanga—engari ka warewarehia ngā taipitopito e tino pā ana ki ngā hua.Paura kōrunuma mā he rauemi "māmā noa iho, engari he mea nui". Mena kei te whakahou koe i tōu ake whare, kei te mahi rānei koe i roto i te umanga tiaki kōhatu, i te wā e whai wāhi atu ai koe ki te tukanga whakakanapa, me pātai atu anō koe i tētahi atu pātai: "He aha te momo paura moroiti e whakamahia ana e tātou?" Tērā pea he rerekē rawa te pānga whakamutunga nā tēnei pātai.
