1. Ke Hobane'ng ha Sekheo sa ho Ithuta se Fetotse Kaho ea Metal
Bakeng sa marulelo, likonteraka tse koahelang, li-installer tsa HVAC, le basebetsi ba kenyang liphanele tsa solar, sekoti sena ke khetho ea kamehla ea ho lokisa tšepe e tšesaane ea gauge. 'Me hobane sekoti sa ho itšeha hangata se phunya litšepe tse se nang letho kapa tse entsoeng ka masenke ka ntle, eona anti-corrosion performance e bohlokoa joalo ka ts'ebetso ea eona ea ho cheka - sekoti se chekang hantle empa se rusa ka linako tse peli se tla lutla, se silafatse, 'me qetellong se hlolehe.
2. Kamoo Sekoahelo sa ho Icheka se Sebetsang Kateng
Sekurufu sa ho itšebetsa ke sekurufu sa tšepe se thata seo ntlha ea sona e siloang hore e be boro e nyenyane ea ho sotha. Lethathamo la ts'ebetso tabeng ena ke:
1.Boemo- screw e lutse holim'a lakane e ka holimo tlas'a khatello e khanyang le lebelo.
2. Qeta- ntlha e nang le fluted e khaola lesoba le hloekileng ka tšepe; Likolilo li phahamisa moqomo e le hore litsupa li se ke tsa koala likhoele.
3.Sebopeho sa khoele- ha ntlha ea ho phunya e tsoa tšepe ea motheo, ketso ea ho itšeha e emisa 'me likhoele li kopanela, li phunyeletsa ka har'a substrate.
4.Clamp- hlooho e hula liphanele hammoho; washer e tiisang (haeba e kentsoe) e hatella ho etsa tiiso e thibelang boemo ba leholimo, e hananang le mafome.
Molao oa bohlokoa oa moralo ke ho tsamaisana le botenya: boholo ba ntlha e 'ngoe le e' ngoe ea ho phunya e na le matla a ho phunya - ntlha ea 2 ka tloaelo e sebetsana le hoo e ka bang 0.6-2.5 mm ea tšepe eohle, ha ntlha ea No. Ho khanna sekoti se fetang matla a sona ho chesa ntlha, ho sebetsa-ho thatafatsa tšepe, 'me ho hlahisa lenonyeletso le hlephileng, le khonang ho bola.
| Sebaka sa ho phunya | Kakaretso ea matla a ho cheka (tšepe) | Tšebeliso e tloaelehileng | Sebaka sa bophara ba screw |
| No. 1 | ho fihlela ho ~ 0.6 mm | Letlapa le bobebe ho lakane | 3.5–4.2 mm (#8–#10) |
| No.2 | 0.6-2,5 limilimithara | Ho rulela, ho koaheloa, li-purlins | 4.2–5.5 mm (#8–#12) |
| No.3 | 1.7–4.5 limilimithara | Ho etsa foreimi ea tšepe ea sebopeho | 4.8–6.3 mm (#12–#14) |
| No.4 | 3.0–6.5 limilimithara | Mekhahlelo e boima ea foreimi | 5.5–6.3 mm (#12–#14) |
| No.5 | 6.0–12.5 limilimithara | Letlapa le letenya la tšepe | 6.3 limilimithara (#14) |
3. Bothata ba Corrosion - le Kamoo Screw Coatings e loantšang mafome ka teng
Sekurufu sa ho itšeha ke sekoahelo se le seng se pepeneneng ka ho fetesisa se enfelopong ea moaho. E lutse mateanong a lilakane tse peli kapa ho feta, e mamella lilemo tse ngata tsa UV, pula le libaesekele tse futhumetseng, 'me hlooho ea eona hangata e ithorisa ka mokhoa oa ho roala. Hang ha mafome a hlaha hloohong, letheba le theohela holim'a phanele, mochini o tiisang o lahleheloa ke khatello, 'me lenonyeletso le qala ho lla.
lZinc electroplating (e tšoeu / e mosehla / e putsoa e fetelletseng). Motheo oa moruo. Ho hlaka kapa ho tšehla trivalent passivation ho liehisa mafome a masoeu, 'me 5-8 µm ea zinki e fana ka lihora tse ka bang 200-400 ho mafome a masoeu tekong ea spray ea letsoai e sa nke lehlakore (ISO 9227 / ASTM B117). E loketse ka hare le ka ntle e sirelelitsoeng.
lMechanical galvanizing. Zinc phofo e tšeloa ka metsi a batang holim'a sekoti, 'me e haha lesela le letenya, le arohaneng ka mokhoa o ts'oanang (ho fihla ho 40-55 µm) ntle le hydrogen embrittlement - molemo oa bohlokoa oa ho thibela ho bola ho feta electroplating bakeng sa likurufu tse thata.
4. Qetello
The self-dolling screws compresses ho cheka, ho roala le ho fastening ka motsamao o le mong, 'me ka ho etsa joalo e fetohile tlamo ea sebopeho le e sa keneleng metsi e tšoarang lienfelopo tsa tšepe tsa morao-rao hammoho. Empa boleng ba 'nete ba boenjineri bo ka har'a ho kopanngoa ha thepa e' meli: sebaka sa ho phunya se thata, se boholo bo nepahetseng se etsang lesoba le hloekileng, le sistimi e sebetsang e phahameng e thibelang kutu e bolokang screw e se na mafome bophelo bohle ba moaho. Khetha screw ka ho phunya, 'me u khethe sekoaelo ka data-spray - 'me screw e tla feta phanele eo e e tšoereng.
