Izikrufu zetsimbi estainless vs. izikrufu zentsimbi yekhabhoni: Unokukhetha njani esona sisombululo silungileyo sokuqinisa?

Kwimimandla yokwakha, ukuveliswa koomatshini kunye nokugcinwa kobunjineli, ukhetho lwezikrini luchaphazela ngokuthe ngqo ukhuseleko lwesakhiwo, iindleko zokugcinwa kunye nobomi beprojekthi. Abathengi abaninzi bahlala bewela kwingxaki: izikrini zetsimbi ezingenasici zibiza kakhulu, kwaye i-carbon steel screws kulula ukugqwala - indlela yokukhetha? Njengomenzi we-fastener oyingcali, Umzi-mveliso weNanning Aozhan uya kukunceda ufumane esona sisombululo ngokuthelekisa ukusebenza + iimeko zokwenyani!

Umahluko obalulekileyo phakathi kwentsimbi engatyiwa kunye nezikrufu zentsimbi yekhabhoni

1. Ukumelana nokubola: isitshixo ekumiseleni ubomi benkonzo

Izikrufu zensimbi ezingenasici (ezifana ne-304/316) zine-chromium kunye ne-nickel, enokuthi ngokwemvelo yenze umaleko okhuselayo we-oxide ukuxhathisa ukufuma, isitshizi setyuwa kunye nokubola kweekhemikhali. I-Carbon steel screws iya kuhlwa kwiinyanga ezi-6-12 kwindawo enomswakama, ngakumbi kwiindawo eziselunxwemeni okanye kwiindawo zoshishino, apho izinga lokubola likhawuleza.

Imeko yokwenyani: Indawo yokugcina izinto isetyenziselwe izikrufu zentsimbi yekhabhoni ukulungisa isakhiwo sentsimbi. Emva kweminyaka eyi-3, iipaneli zephahla zikhululekile ngenxa yokugqwala, kwaye iindleko zokulungisa zadlula i-US $ 50,000; ngelixa i-warehouse efanayo eyatshintshela kwi-screws ye-stainless steel engama-304 yayingenayo ingxaki yokubola iminyaka eyi-10.

2. Ukuthelekisa amandla: ayizizo zonke iimeko ezifuna amandla aphezulu

Izikrufu zentsimbi yekhabhoni zidla ngokuba namandla aphezulu okuqina (afana ne-8.8, 10.9), zilungele izakhiwo ezinobunzima. Nangona kunjalo, amandla e-screws yensimbi engenasici (efana ne-A2-70, A4-80) inokuhlangabezana neyona mfuno yokwakha kunye nemishini. Ngaphandle kokuba yimeko ethwele umthwalo ogqithisileyo (efana neebhulorho, oomatshini abanzima), akukho mfuneko yokusukela ngokugqithisileyo amandla aphezulu.

3. Uhlalutyo lweendleko: ukonga imali yexesha elifutshane xa kuthelekiswa nexabiso lexesha elide

Iindleko zokuqala zokuthengwa kwe-carbon steel screws yi-30% -50% ephantsi kuneyensimbi engenasici, kodwa unyango oluqhelekileyo lokulwa ne-rust okanye ukutshintshwa luyafuneka. Kwiindawo ezifumileyo, ezine-acidic kunye ne-alkaline, iindleko zomjikelo wobomi obupheleleyo bezikrufu zensimbi ezingenasici ziphantsi-ukuphelisa ukugcinwa rhoqo kunye nokulahleka kwexesha lokuphumla.

Isikhokelo sokuKhetha: Khetha ngokwemeko yesicelo sakho

Imeko yokukhetha izikrufu zentsimbi yekhabhoni

1. Izakhiwo zexeshana elifutshane (ulwakhiwo lwemiboniso, iindawo ezivaliweyo zethutyana)
2. Indawo eyomileyo yangaphakathi (uhombiso lweofisi, indibano yefenitshala)
3. Iiprojekthi ezingabizi kakhulu kwaye zinokuvuma ukutshintshwa rhoqo

Imeko yokukhetha izikrufu zentsimbi engenasici

1. Iindawo zokuvezwa ngaphandle (uphahla, iintsimbi zokugada, izibonelelo zothutho)
2. Ukufuma okuphezulu/iindawo ezinetyuwa eninzi (izakhiwo eziselunxwemeni, iinqanawa, izityalo zemichiza)
3. Ukutya kunye nezixhobo zonyango (kufuneka zihlangabezane nemigangatho yococeko)
4. Iindawo ezinzima-ukugcina (izakhiwo eziphakamileyo, imibhobho engaphantsi komhlaba)

Izisombululo ezilungiselelwe uNanning Aozhan

Siyaziqonda iimfuno ezizodwa zeprojekthi nganye, ngoko sibonelela:

1. Inkonzo yovavanyo lwezinto: kukunceda uqinisekise ukuba izikrufu ezikhoyo zifanelekile kwindawo yangoku
2. Isisombululo sokusetyenziswa okuxubileyo: sebenzisa insimbi engenasici kwiindawo eziphambili kunye ne-carbon steel kwiindawo ezingezona eziphambili zokwandisa iindleko
3. Ukuphuculwa konyango lomphezulu: I-Dacromet / i-hot-dip galvanizing ye-carbon steel screws ukwandisa ubomi

Kutheni ukhetha thina?

I-10 + iminyaka yokugxila kwimveliso ye-fastener, ngokuhambelana nemigangatho ye-ISO / GB / DIN

Xhasa ii-odolo zovavanyo lwebhetshi encinci, qinisekisa umphumo phambi kokuthengwa kwezinto ezinkulu

Ukubonelela ngengxelo yovavanyo lomngcipheko wokutya ukuthintela iimpazamo zokukhetha
