Product Description
Copper hleb screws yog tshwj xeeb fasteners tsim los sib sau ua ke, kev ruaj ntseg, los yog sealing hleb (casket) Cheebtsam, integrating functional durability nrog kev coj noj coj ua thiab tswv yim (adaptability). Lawv cov qauv tsim thiab kev ua tau zoo yog ua raws li cov kev cai tshwj xeeb ntawm kev tsim lub hleb -xws li kev tiv thaiv corrosion (kom muaj kev ntseeg ruaj khov nyob rau lub sijhawm), tuav lub zog ruaj khov (kom lub hleb tsis zoo), thiab ua raws li qee qhov kev coj noj coj ua lossis kev lag luam rau cov khoom siv pam tuag. Hauv qab no yog cov lus piav qhia ntxaws thoob plaws qhov loj me:
1. Cov yam ntxwv ntawm cov khoom: Cov yam ntxwv tseem ceeb ntawm tooj liab alloys
Copper hleb screws tsis yog ua los ntawm ntshiab tooj liab (uas yog mos heev rau load-bearing) tab sis cov tooj liab alloys (tooj liab-zinc-raws li) los yog tshwj xeeb tooj liab alloys, xaiv rau lawv lub zog sib npaug, corrosion resistance, thiab workability.
Common Alloys:
C2680 Brass (70/30 Brass): Cov khoom siv dav tshaj plaws, muaj ~ 70% tooj liab thiab ~ 30% zinc. Nws muaj kev ua haujlwm zoo heev (yooj yim los txiav cov xov thiab cov duab), lub zog nruab nrab, thiab ntuj tiv thaiv rau atmospheric corrosion- tseem ceeb heev rau kev tiv thaiv xeb lossis degradation yog tias lub hleb khaws cia lossis faus rau lub sijhawm ntev.
C2800 Brass (65/35 Brass): Nrog cov ntsiab lus zinc ntau dua (~ 35%), nws muaj zog me ntsis siab dua li C2680, thaum khaws zoo corrosion kuj. Nws feem ntau yog siv rau cov ntsia hlau uas yuav tsum tau dais lub zog tensile ntau dua (xws li, ruaj khov hleb sab panels).
Tshwj xeeb Alloys (piv txwv li, CuSn5Pb5Zn5): Rau siab -xav tau scenarios, me me ntawm tin (Sn) los yog txhuas (Pb) ntxiv los txhim kho hnav tsis kam thiab xov smoothness, kom ntseeg tau tias cov ntsia hlau tuaj yeem nruj / loosened yam tsis muaj xov stripping (tseem ceeb rau kev kho lub hleb lossis kev hloov kho thaum tsim khoom).
Nrig txog kev pom & Tactile Nta: Ntuj tooj dag ntsia hlau muaj qhov sov so kub -xim av xim av, uas tuaj yeem ntxiv cov hleb ntoo (tsis txhob ua kom txias txias ntawm cov hlau ntsia hlau). Qhov saum npoo feem ntau yog polished los yog txhuam kom txo cov burrs, tiv thaiv khawb rau lub hleb ntoo los yog ntaub hauv ob sab phlu thaum lub sij hawm installation.
2. Tus Qauv Tsim: Tsim kom haum rau lub hleb los ua ke xav tau
Txhua feem ntawm cov ntsia hlau cov qauv yog optimized rau txuas lub hleb Cheebtsam (xws li, ntoo panels, tuav, hniav trim), ua ntej tuav ruaj khov thiab kev puas tsuaj tsawg kawg nkaus rau cov khoom hleb.
(1) Xov Tsim
Xov Hom: Feem ntau siv metric coarse threads (piv txwv li, M4, M5, M6, M8), uas muaj cov xov loj dua (piv txwv li, M4 muaj 0.7mm suab). Qhov kev tsim no muaj zog tuav hauv cov ntoo mos (ntau ntau hauv hleb, xws li ntoo thuv, cedar) los ntawm kev ua kom thaj chaw sib cuag nrog ntoo- tiv thaiv cov ntsia hlau los ntawm loosening vim ntoo nthuav dav / kev cog lus.
Xov Length: Feem ntau suav rau 2/3 txog 3/4 ntawm tag nrho cov ntsia hlau ntev. Piv txwv li, 20mm-ntev M5 ntsia hlau yuav muaj 12-15mm ntawm cov xov uas siv tau. Qhov no ua kom cov ntsia hlau nkag mus rau lub hom phiaj lub vaj huam sib luag kom txaus (tsis tas yuav mus rau txhua txoj hauv kev los ntawm thiab ua kom puas lub hauv ob sab hauv) thaum tawm hauv lub luv luv unthreaded shank kom txo kev sib txhuam thaum lub sij hawm installation.
Xov Xaus: Cov xov feem ntau dov (txias- tsim) tsis yog txiav. Rolled threads muaj ib tug smoother nto thiab muaj zog tensile zog, txo txoj kev pheej hmoo ntawm kev sib cais ntawm cov ntoo thaum lub ntsia hlau yog tsav mus rau hauv (qhov kev txhawj xeeb tseem ceeb rau cov khoom siv hleb zoo li cedar).
(2) Lub taub hau hom
Lub taub hau tsim kev sib npaug ntawm kev ua haujlwm (kev yooj yim installation) thiab kev zoo nkauj (tso kom pom qhov cuam tshuam ntawm lub hleb qhov tsos):
Flat Head (Countersunk Head): Hom ntau tshaj plaws. Lub taub hau muaj cov duab conical (feem ntau yog 90℃lossis 120℃lub kaum sab xis) uas zaum yaug nrog lub hleb saum npoo thaum nruj nruj. Qhov no tiv thaiv lub taub hau los ntawm protruding thiab ntes ntawm cov ntaub, thiab tseem tso cai rau sau los yog pleev xim rau ntawm lub taub hau kom nkaum nws - zoo tagnrho rau cov chaw pom zoo li lub hleb lub hau los yog pem hauv ntej vaj huam sib luag.
Lub taub hau lub taub hau (Round Head): Siv rau cov uas tsis yog - pom lossis ua haujlwm (piv txwv li, kev ruaj ntseg sab hauv cov kab hluav taws xob). Lub taub hau me ntsis muab lub ntsej muag loj dua, faib lub siab sib npaug kom tsis txhob tsoo cov ntoo nyias nyias. Nws feem ntau ua ke nrog lub tshuab ntxhua khaub ncaws kom ntxiv kev ruaj ntseg.
