90% by'abantu bakandagiye kuri ubu 'bumenyi bukonje bw'abakoresha'

Uyu munsi, ndavuga ukuri ko ntatinyuka kuvuga ku mugaragaro muri uru rwego, kandi namara kurusoma, nzazigama nibura 30% by'ingengo y'imari.
1. Ibara ry'urukiramende ≠ urwego rw'ubuziranenge
Ifeza ni zinc ikozwe mu buryo bwa elegitoroniki, umukara ni irangi ry'umukara risutsweho, kandi ikiguzi cy'uburyo bubiri bwo gutunganya ni kimwe. Tanga commande ukurikije uko igaragara. Ntugashukwe n'imvugo ngo 'uko irangi rinini, ni ko ririnda ingese'. Ikintu nyacyo kigena ubushobozi bwo kwirinda ingese ni igihe cyo gupima umunyu, si ibara.
2. Feri yo ku ruhande cyangwa feri ebyiri? Banza urebe aho ibicuruzwa byoherejwe mbere yo gutumiza
90% by'ama-oda aturutse i Burayi na Amerika akoresha feri zo ku ruhande - zifite imiterere yoroshye kandi ihendutse, kandi nizivunika, ipine yose izasenyuka;
90% by'ibikoresho byo mu gihugu bikoresha feri ebyiri - zifite imiterere yo kuri interineti kandi uburebure bwo kuyishyiramo bukaba 3mm, bikaba bihenze cyane ku kigero cya 8% -12%.
Umwanzuro: Hitamo feri zo ku ruhande zo kohereza ibikoresho mu mahanga n'feri ebyiri zo ku bicuruzwa bikunzwe mu gihugu, nta tandukaniro riri mu mikorere. Ntukibeshye "umusoro w'ubwiza" n'"umusoro ku bushobozi".
3. Ese amapine y'icyuma aramba cyane? Ni ibihuha byo mu kinyejana gishize gusa
Amapine amwe ya santimetero 4, ubwoko bwa nylon bukozwe mu buryo bukomeye kandi bufite ubushobozi bwo gutwara imizigo bugera kuri kg 280, ubwoko bwa steel bukozwe mu buryo bwa cast steel bufite kg 260, araremereye, aranguruye, kandi ashobora kwangirika cyane. Impamvu yatumye amapine y'icyuma agumaho n'uyu munsi ni imwe gusa - ubwo igiciro cya aluminiyumu cyazamukaga, cyari kihendutse kuri yuan 0.8 ku gice.

4. "Uburinganire bw'icyuma = kurwanya ingese" ni intero y'ubucuruzi

Amapine ya PU, nylon, na rubber aturuka mu nganda zemewe zose zatsinze ikizamini cyo gusukura umunyu mu masaha 48, mu gihe amapine y'icyuma yatangiye kwangirika nyuma y'amasaha 24 yo gupimwa kubera kwangirika kw'amashanyarazi. Gukoresha amafaranga 15% y'inyongera kugura "ikintu gikozwe mu buryo bwa kawa" ni akarengane?
5. Ese amapine ya rubber yoroshye kurusha PU? Arashobora guhindurwa! Arashobora guhindurwa! Arashobora guhindurwa!
Kongeramo pulasitiki ya 5% kuri formula bishobora kongera ubukana bw'amapine ya rubber kugeza kuri 95 A, irusha nylon gukomera; PU ya 65A ishobora gukoreshwa nk' 'ikoti rya cotton ritagira impumuro'. Mbere yo gutumiza, saba umugurisha kukwereka icyuma gipima ubukana bwa Shore, ntukongere gushukwa n'amagambo 'rubber yoroshye'.
6. Imiterere ibiri = imitere miremire, imitere imwe = imitere yo hasi? Reba aho ibintu bibera!
Ibyuma bibiri: umutwaro mwinshi udahinduka, urusaku ruto, bihenze 30%, bikwiriye ibikoresho byo kwa muganga n'imodoka zo kuriramo zigezweho;
Ifite umuvuduko umwe: umutwaro mwinshi uhinduka, ubushobozi bwo gutangira buhoro, igiciro gito cya 30%, kibereye imodoka zitwara imizigo n'uduseke tw'ingufu.
Gushyiramo umuvuduko w’umuvuduko w’umurambararo ku kirenge cy’umurongo w’iteraniro bizagabanya umuvuduko; Umuforomo yinubiye urusaku ku munsi wakurikiyeho nyuma yo gushyiramo umuvuduko w’umuvuduko umwe mu gitanda cya ICU. Fata umuti ukwiye, ntukawushyiremo kabiri nk’umuntu utabizi.
7. Igipimo cy'ibipimo ni santimetero, ntabwo ari "santimetero zo ku isoko"!
Ingano zikunze kuvugwa ku isoko za santimetero 3, santimetero 4, na santimetero 5 zose zerekeza kuri santimetero 1 “=25.4 mm.”
Santimetero 3 ≈ mm 75, santimetero 4 ≈ mm 100, santimetero 5 ≈ mm 125.
Kwandika santimetero 4 nka "100 mm" ni byiza, ariko kwandika nka "santimetero 4 zo ku isoko" (≈ mm 133) ni ugutegereza gusa kugaruza.
