I tēnei rā, ka kōrerotia e au te pono kāore au e maia ki te kōrero tūmatanui i roto i te umanga, ā, i muri i taku panuitanga, ka penapenahia e au te 30% o te tahua.
1. Tae o te pūwero ≠ taumata kounga
Ko te hiriwa he konutea whakakikoruatia ki te hiko, ko te mangu he peita pango rehuhia, ā, tata rite tonu te utu mō ngā tikanga tukatuka e rua. Me tuku noa he ota i runga i te āhua. Kaua e tinihangatia e te kīwaha 'ki te matotoru ake te paninga, ka nui ake te ātete ki te waikura'. Ko te mea tino whakatau i te kaha ki te ārai waikura ko te roa o te whakamātautau rehu tote, ehara i te tae.
2. Pēra taha, pēra takirua rānei? Tirohia tuatahi te wāhi kaweake i mua i te tuku ota
E 90% o ngā ota mai i Ūropi me Amerika e whakamahi ana i ngā pēra taha – he māmā noa iho, he iti hoki te utu o te hanganga, ā, ki te pakaru, ka para katoa te wira;
E 90% o ngā tūāpapa hokohoko ipurangi ā-rohe e whakamahi ana i ngā pērai takirua – he āhua tuihono, ā, he teitei tāutanga tāpiri o te 3mm, he 8% -12% te utu nui ake.
Whakatau: Kōwhiria ngā pēra taha mō ngā taputapu kaweake me ngā pēra takirua mō ngā hua o roto rongonui, kāore he rerekētanga o te mahi. Kaua e pohehe te "taake ataahua" ki te "taake mahi".
3. He pakari ake ngā wira rino? He kōrero pakiwaitara noa iho nō te rautau kua taha ake nei
Ko ngā wira 4-inihi, he momo wīra werohanga nairona kaha-teitei me te kaha kawe kawenga hihiri o te 280 kg, ko te momo rino maka he 260 kg, he taumaha ake, he haruru ake, ā, he ngāwari ake te waikura. Ko te take e ora tonu ai ngā wīra rino maka i ēnei rā kotahi noa iho - i te pikinga o te utu o te konumohe maka, he 0.8 yuan te iti iho i te kotahi wahi.
4. He pepeha hokohoko te "Ihirangi rino = ātete ki te waikura"
Kua paahitia e ngā wira PU, nairona, me te rapa mai i ngā kaihanga tika te whakamātautau rehu tote kūpapa 48 hāora, i te mea kua tīmata te waikura o ngā wira rino i muri i ngā hāora 24 o te whakamātautau nā te waikura hikohiko. He hē te whakapau moni 15% atu ki te hoko i tētahi "taonga waikura e mau ana i te kawenga"?
5. He ngohengohe ake rānei ngā wira rapa i te PU? Ka taea te whakarerekē! Ka taea te whakarerekē! Ka taea te whakarerekē!
Mā te tāpiri i tētahi atu 5% plasticizer ki te tauira ka taea te whakanui ake i te pakeke o ngā wira rapa ki te 95 A, he pakeke ake i te nairona; ka taea te whakamahi i te PU o te 65A hei 'koti miro wahangu'. I mua i te tuku ota, tonoa te kaihoko kia whakaaturia ki a koe he whakamātautau pakeke Shore, kaua e tinihangatia e ngā kupu 'rapa ngohengohe' i muri mai.
6. He whāriki takirua = he whāriki teitei, he whāriki kotahi = he whāriki iti? Tirohia te tirohanga!
Ngā peera takirua: he nui te kawenga pateko, he iti te haruru, he 30% te utu, he pai mō ngā taputapu hauora me ngā waka kai papai;
Kotahi te whāriki: he nui te kawenga hihiri, he iti te ātete tīmatanga, he 30% te utu iti iho, he pai mō ngā kaata kawe me ngā kete hurihanga.
Mā te tāuta i te whāriki tuaka rua ki te waewae o te raina huihuinga ka whakaroa noa i te tere; I amuamu te nēhi mō te haruru i te aonga ake i muri i te tāutanga o te whāriki kotahi ki te moenga ICU. Tangohia te rongoā tika, kaua e 'tāruarua' noa.
7. Ko te ine he inihi, ehara i te "inihi mākete"!
Ko ngā rahi e mōhiotia whānuitia ana i te mākete ko te 3-inihi, 4-inihi, me te 5-inihi e pā ana ki te inihi 1 "=25.4 mm.
3 inihi ≈ 75 mm, 4 inihi ≈ 100 mm, 5 inihi ≈ 125 mm.
He pai te tuhi i te 4 inihi hei "100 mm", engari ko te tuhi i te "4 inihi mākete" (≈ 133 mm) he tatari noa kia whakahokia mai.
