Zomangira zowuma zimagwira ntchito yofunika kwambiri pamoyo watsiku ndi tsiku

Screw ndi chida chaching'ono komanso chosawoneka bwino m'moyo wathu. Ngakhale zingawoneke zazing'ono, ndi code yogwira ntchito yomwe sitingathe kukhala popanda. Ndi ntchito yaing'ono yokhala ndi udindo wofunika kwambiri komanso mphamvu zambiri. Imakhala ndi zotsatira zosinthika kwambiri, zomangira zowuma zili ndi gawo lake lapadera m'miyoyo yathu. Tsopano, monga opanga zinthu, mtundu wonse wa zomangira zathu zowuma ndi zabwino kwambiri ndipo mtundu wonse ndi wabwino kwambiri.

Zomangira akadali chida chaching'ono chofunikira kwambiri pantchito yonse yomanga. Popanda chida chaching'ono chotere, sitingathe kuchita mitundu yonse ya ntchito zokhazikika, mitundu yonse yokongoletsera nyumba ndi kumanga nyumba. Zomangira zowuma ndi zida zina zing'onozing'ono zitha kugwiritsidwa ntchito limodzi, zokhala ndi mawonekedwe abwino komanso kukonza. Popanda chida chaching'ono chotere, zingakhale zovuta kuyankhula za zolemba zina zosungirako matabwa m'nyumba mwathu kapena kufotokoza mwachidule makulidwe osiyanasiyana opangira m'zipinda zathu. Ichi ndi chida chofunikira kwambiri kwa ife.

Tsopano wopanga wathu zomangira zowuma amapanga misomali. Ubwino wonse ndi wabwino kwambiri, mtundu wofananira ndi wabwinoko, moyo wabwino wautumiki wa gulu lamaphunziro mwachilengedwe ndi wautali, chifukwa tsopano opanga ng'ombe athu asintha bwino pazinthu zonse, magwiridwe antchito ofananira nawo adasinthidwa bwino, ndipo sewero lathu lachita bwino kugwiritsa ntchito.

Mtengo wa zomangira zowuma pamsika tsopano umasiyana kwambiri. Zomangira zotsika mtengo zomangira zimangopitilira matani 5,000, pomwe zomangira zokwera mtengo zimakhala pafupifupi kuwirikiza kawiri kwa zomangira zanthawi zonse. Chifukwa chiyani mitengo ili yosiyana? Kodi ndikusintha kwazinthu kapena vuto pakupanga?

Kuchiza kwakunja kwakunja kwa zomangira zouma zowuma ndi njira yosinthira vuto la zigawo zachitsulo ndi njira zosiyanasiyana zoziziritsa. Tsopano ambiri ntchito matenthedwe kunja mankhwala ali ndi moto. Moto wonse ndi kutenthetsa, kodi njira zitatuzi zimabweretsa chiyani?

1. Drywall screw quenching: kutentha chitsulo kupitirira 942 ℃, kotero kuti chitsulo chimawonetsa dziko la austenitic, ndiyeno muyike m'madzi ozizira kapena kuzimitsa mafuta ozizira, kuti chitsulo chiwonetsere katundu wa martensite. Njira yowonetserayi imawonjezera mphamvu ndi kuuma kwachitsulo. Mphamvu ndi kuuma kwazitsulo zamakalasi a zitsanzo zimasiyana kwambiri pakati pa zitsulo zozimitsidwa ndi zosazimitsidwa

2. Drywall screw annealing: Njira yochizira kutentha yomweyi yomwe imatenthetsa chitsulo kuti chikhale chokhazikika ndikuziziritsa mlengalenga. Njirayi imatha kuchepetsa mphamvu ndi kuuma kwachitsulo, kusintha kusinthasintha kwachitsulo, kosavuta kukonza. Nthawi zambiri, chitsulo chimadutsa mu sitepe iyi chisanayambe kukonzedwa

3, kutentha: kaya kuzimitsa, kutsekemera kapena kupanikizika, kumapangitsa kuti pakhale kupanikizika kwamkati m'zigawo zachitsulo, ndipo kusalinganika kwa kupanikizika kwamkati kumakhudza mphamvu ya kapangidwe kazitsulo ndi ziwalo zamakina kuchokera mkati, kotero ziyenera kukhala zochepetsetsa. Zinthuzo zimasungidwa m'nyumba kutentha pamwamba pa madigiri 700 kuti zisinthe kupsinjika kwake kwamkati, kenako kuzikhazikika mwachibadwa.
