1. Ihe mere ihe nkedo nke onwe ya ji gbanwee ihe owuwu ígwè

Maka ndị na-arụ ụlọ, ndị na-arụ ọrụ mkpuchi mkpuchi, ndị na-arụ ọrụ HVAC, na ndị na-arụ ọrụ na-arị elu anyanwụ, screw a bụ nhọrọ a na-adịghị mma maka idozi ígwè dị mkpa. Na n'ihi na skru nke na-egwupụta onwe ya na-apukarị ígwè efu ma ọ bụ galvanized n'èzí, ya arụmọrụ mgbochi corrosion dị oke mkpa dị ka arụmọrụ mkpọpu ya - skru nke na-akpụ akpụ nke ọma mana nchara n'ime oge abụọ ga-adapụta, ntụpọ, ma mechaa daa.

2. Kedu ka ihe nkedo nke onwe ya si arụ ọrụ

Ihe nkedo nke na-egwupụta onwe ya bụ ịghasa nchara siri ike nke ọnụ ya gbadara n'ime mkpụgharị obere mgbagharị. Usoro ọrụ n'oge a bụ:

1. Ọnọdụ- ịghasa na-anọdụ ala n'elu mpempe akwụkwọ n'okpuru ìhè nrụgide na ọsọ.

2.Drill- ọnụ na-efegharị efegharị na-egbutu oghere dị ọcha site na nchara; ọjà na-ebuliri eju ka ibe ya ghara imechi eri.

3.Thread-ụdị- ka ebe a na-egwupụta ihe na-apụ na nchara isi, ihe nkwụsị ahụ na-akwụsị na eri na-etinye aka, na-abanye n'ime mkpụrụ.

4.Mkpade- isi na-adọta ogwe ọnụ; ihe na-asachapụ ihe (ma ọ bụrụ na ọ dabara) na-akpakọ ka ọ bụrụ akara ihu igwe na-adịghị egbochi nchara.

Iwu imewe dị oke egwu bụ ọkpụrụkpụ dakọtara: onye ọ bụla akuakuzinwo n'ókè size nwere a mkpọpu ala ikike - a No. 2 isi a ejiri banyere 0.6-2.5 mm nke ngụkọta ígwè, mgbe a No. 5 ebe nwere ike akuakuzinwo ruo banyere 12.5 mm. Ịkwọ ụgbọ ala karịa ikike ya na-ere ọnụ ọnụ ya ọkụ, na-arụ ọrụ na-eme ka ígwè ahụ sie ike, ma na-emepụta nkwonkwo na-adịghị mma, nke na-adị mfe corrosion.

Ebe egwu egwu	Mkpokọta ike mkpọpu ihe (igwe)	Ngwa a na-ahụkarị	Oke dayameta ịghasa
Nke 1	ruo ~ 0.6 mm	Akwụkwọ ọkụ na mpempe akwụkwọ	3.5-4.2 mm (#8-#10)
Nke 2	0.6-2.5 mm	Ime ụlọ, mkpuchi, purlins	4.2-5.5 mm (#8-#12)
Nke 3	1.7-4.5 mm	Nhazi nchara nchara	4.8-6.3 mm (#12-#14)
Nke 4	3.0-6.5 mm	Nhazi ihe nleba anya	5.5-6.3 mm (#12-#14)
Nke 5	6.0-12.5 mm	Efere ígwè dị oké njọ	6.3 mm (#14)

3. Nsogbu corrosion - yana ka mkpuchi mkpuchi na-alụ ọgụ nchara

Ihe nkedo nke na-egwupụta onwe ya bụ otu ihe mgbochi ekpughere nke ọma na envelopu ụlọ. Ọ na-anọdụ na nkwụsị nke abụọ ma ọ bụ karịa galvanized Ibé akwụkwọ, na-edi ọtụtụ afọ nke UV, mmiri ozuzo, na thermal ịgba ígwè, na isi ya na-adịkarị mpako maka usoro mkpuchi. Ozugbo nchara dị n'elu pụtara n'isi, ntụpọ ahụ na-agbada na panel ahụ, ihe nchara na-ekpuchi ya na-efunahụ mkpakọ, nkwonkwo ahụ na-amalite ịkwa ákwá.

lZinc electroplating (ọcha / odo / acha anụnụ anụnụ passivated). Ntọala akụ na ụba. Nri doro anya ma ọ bụ odo odo na-ebelata nchara ọcha, yana 5-8 µm nke zinc na-enye ihe dị ka awa 200-400 maka nchara ọcha na nnwale ịgba nnu na-anọpụ iche (ISO 9227 / ASTM B117). Kwesịrị ekwesị maka ime ime na ebe nchekwa.

lMechanical galvanizing. Zinc ntụ ntụ bụ oyi-welded n'elu ịghasa n'elu, na-ewu a thicker, otu nkesa mkpuchi (ruo 40-55 µm) na-enweghị hydrogen embrittlement - mkpa mgbochi corrosion uru n'elu electroplating maka skru siri ike.

4. Mmechi

Ihe nkedo a na-egwupụta onwe ya na-ejikọta mkpọpu, threading na fasting n'ime otu mmegharị, na ime nke a, ọ ghọwo ihe nhazi na mmiri na-adịghị mma nke na-ejikọta envelopes ígwè ọgbara ọhụrụ. Ma ya n'ezie engineering uru dabeere na pairing nke abụọ Njirimara: a kpọrọ okuku ume, n'ụzọ ziri ezi sized ebe na-eme ka oghere dị ọcha, na a elu-arụmọrụ mgbochi corrosion mkpuchi usoro na-eme ka ịghasa nchara-free maka ndụ nke ụlọ. Họrọ ịghasa site na mkpọpu ikike, wee họrọ mkpuchi site na data ịgbasa nnu - na ịghasa dị umeala n'obi ga-agafe panel nke ọ na-ejide.

Enweghị. Na-esote.
