Self-Drilling Screws

1. Kutheni i-Self-Drilling Screw yatshintsha ulwakhiwo lweMetal

Kumagumbi ophahla, iikontraka ezigqumayo, izifakeli ze-HVAC, kunye nabasebenzi abanyusela i-solar-panel, esi sikrufu ngoku lukhetho olungagqibekanga lokulungiswa kwentsimbi ecekethekileyo yegeyiji. Kwaye ngenxa yokuba isikrufu sokuzibhora siqhele ukugqobhoza ngaphandle okanye intsimbi efakwe igalvanized ngaphandle, yaso ukusebenza anti-corrosion kubaluleke kanye njengoko ukusebenza kwayo yokomba -Isikrufu esomba kakuhle kodwa sivuthe kumaxesha amabini onyaka siya kuvuza, sibe nebala, kwaye ekugqibeleni sisilele.

2. Sisebenza njani isikruru sokuZimbela

I-self-drilling screw sisikrufu sentsimbi eqinisiweyo esincam yaso igutywe ibe sisikroba esincinci sokujija. Ukulandelelana kokusebenza kwinqanaba kukuba:

1.Isikhundla- i-screw ihleli kwiphepha eliphezulu phantsi koxinzelelo lokukhanya kunye nesantya.

2.Drill- incam ephothiweyo inqumla umngxuma ococekileyo ngentsimbi; iifluti ziphakamisa i-swarf ukuze iitshiphusi zingaze zijame imisonto.

3.Umsonto-ifomu- njengoko i-drill point iphuma kwisiseko sensimbi, isenzo sokusika siyayeka kunye neentambo zibandakanya, zifake kwi-substrate.

4.Bamba- intloko idonsa iipaneli kunye; iwasha yokutywina (ukuba ifakelwe) iyacinezela ukwenza itywina elingagungqiyo kwimozulu, elimelana nomhlwa.

Umgaqo obalulekileyo woyilo ukuhambelana kobukhulu: indawo nganye ye-drill point inomthamo wokugaya - i-No. Ukuqhuba isikrufu esingaphaya komthamo waso kutshisa incam, umsebenzi-wenza lukhuni intsimbi, kwaye uvelise ijoyini ekhululekileyo, ethanda ukubola.

Indawo yokudweba	Umthamo uwonke wokomba (intsimbi)	Usetyenziso oluqhelekileyo	Uluhlu lwe-Screw diameter
Inombolo 1	ukuya kuthi ga kwi ~0.6 mm	Ishiti elikhanyayo ukuya kwiphepha	3.5–4.2 mm (#8–#10)
Inombolo yesi-2	0.6-2.5 mm	Uphahla, ukugquma, ii-purlins	4.2–5.5 mm (#8–#12)
Inombolo yesi-3	1.7–4.5 mm	Ukwakhiwa kwentsimbi yolwakhiwo	4.8–6.3 mm (#12–#14)
Inombolo yesi-4	3.0–6.5 mm	Ukuqulunqa igeyiji enzima	5.5–6.3 mm (#12–#14)
Inombolo yesi-5	6.0-12.5 mm	Ipleyiti yentsimbi eshinyeneyo	6.3 mm (#14)

3. Ingxaki yeCorrosion- kunye nendlela iScrew Coatings ezilwa ngayo nomhlwa

Isikrufu sokuzibhobhoza sesona siqhoboshelo sibonakeleyo kwimvulophu yesakhiwo. Ihlala ekudibaneni kwamaphepha amabini okanye ngaphezulu, inyamezela iminyaka ye-UV, imvula, kunye nokuhamba ngebhayisekile eshushu, kwaye intloko yayo ihlala iyazingca ngenkqubo yokugquma. Nje ukuba kuvele umhlwa phezu kwentloko, ibala lehla kwiphaneli, iwasha yokutywina iphulukana noxinzelelo, kwaye ilungu liqalisa ukulila.

lI-Zinc electroplating (emhlophe / etyheli / eluhlaza okwesibhakabhaka idluliselwe). Isiseko sezoqoqosho. I-trivalent passivation ecacileyo okanye emthubi icothisa umhlwa omhlophe, kwaye i-5-8 µm ye-zinc inika malunga neeyure ezingama-200-400 ukuya kumhlwa omhlophe kuvavanyo lokutshiza lwetyuwa olungathathi hlangothi (ISO 9227 / ASTM B117). Ifanelekile ngaphakathi kunye neendawo zangaphandle ezikhuselweyo.

lUkugalela oomatshini. Umgubo weZinc udityaniswe ngokubanda kumphezulu wesikrufu, wakha umgqumo ongqindilili, osasazwe ngokulinganayo (ukuya kuthi ga kwi-40–55 µm) ngaphandle kwe-hydrogen embrittlement-inzuzo ebalulekileyo yokuchasana nomhlwa ngaphezu kwe-electroplating yezikrufu eziqinisiweyo.

4. Ukuqukumbela

I-self-drilling screw inyanzelisa ukomba, ukuthunga kunye nokuqinisa kwintshukumo enye, kwaye ngokwenza oko kuye kwaba yinto edibeneyo yokwakheka kunye nokungangeni kwamanzi ebamba iimvilophu zentsimbi zanamhlanje kunye. Kodwa ixabiso layo lokwenyani lobunjineli lilele ekudityanisweni kweempawu ezimbini: indawo yokomba eqinile, enobungakanani obuchanekileyo eyenza umngxuma ococekileyo, kunye nenkqubo yokwaleka ephezulu yokusebenza echasene nomhlwa egcina isikrufu singenamhlwa ubomi besakhiwo. Khetha isikrufu ngomthamo wokomba, kwaye ukhethe ukugquma ngetyuwa-idatha yesitshizi - kwaye isikrufu esithobekileyo siya kudlula ipaneli esiyibambe phantsi.

Andinayo. Okulandelayo.
