Self-Drilling Screws

1. Sei Self-Drilling Screw Yakachinja Metal Kuvaka

Kune vanodzika matenga edzimba, vanovhara makondirakiti, maHVAC anoisa, uye solar-panel inokwira vashandi, iyi screw ndiyo yave sarudzo yakasarudzika yekugadzirisa nhete-gauge simbi. Uye nekuti siruu yekuzviboora inowanzobaya simbi isina chinhu kana galvanized panze, its anti-corrosion performance yakakosha sekuchera kwayo - sikuruu inoboora zvinoyevedza asi ichiita ngura mumwaka miviri inobvinza, kusvibisa, uye nekuzokundikana.

2. Iyo Self-Drilling Screw Inoshanda

A self-drilling siruuru isimbi yakaomeswa sikuruu iyo ine muromo unogayiwa kuita kaminiature twist drill. Kutevedzana kwekushanda panguva yacho ndeiyi:

1.Position- iyo screw yakagara papepa repamusoro pasi pekumanikidzwa kwechiedza uye nekukurumidza.

2.Drill- muromo wenyere unocheka gomba rakachena kuburikidza nesimbi; nyere dzinosimudza mbichana zvekuti machipisi haambojaidza shinda.

3.Thread-fomu- sezvo chibooreso chinobuda pachigadziko chesimbi, chiito chekucheka chinomira uye tambo dzinobatanidzwa, dzichipinda mu substrate.

4.Clamp- musoro unodhonza mapaneru pamwe chete; iyo yekuisa chisimbiso washer (kana yakaiswa) inomesa kuti iite chisimbiso chisina kusimba, chinodzivirira ngura.

Mutemo wakakosha wekugadzira ndewe kuenzanisa ukobvu: saizi yega yega yekudhiraivha ine simba rekuchera - 2 point inowanzobata nezve 0.6-2.5 mm yesimbi yakazara, nepo No. Kutyaira sikuruu kupfuura kugona kwayo kunopisa muromo, kushanda-kunoomesa simbi, uye kunoburitsa rakasununguka, rinoita ngura.

Drill point	Huwandu hwekuchera (simbi)	Yakajairika application	Screw diameter range
Nhamba 1	kusvika ~ 0.6 mm	Chiedza pepa kune pepa	3.5–4.2 mm (#8–#10)
Nhamba 2	0.6–2.5 mm	Roofing, cladding, purlins	4.2–5.5 mm (#8–#12)
Nhamba 3	1.7–4.5 mm	Structural steel frameming	4.8–6.3 mm (#12–#14)
Nhamba 4	3.0–6.5 mm	Heavy gauge framing	5.5–6.3 mm (#12–#14)
Nhamba 5	6.0–12.5 mm	Ndiro yesimbi yakakora	6.3 mm (#14)

3. Dambudziko reCorrosion - uye Mabatiro EScrew Coatings Anorwisa Ngura

A self-drilling screw ndicho chibatiso chimwe chete chinonyanyo ratidza ngura pahamvuropu yekuvaka. Inogara panosangana mashizha maviri kana anopfuura, inotsungirira makore eUV, mvura, uye kuchovha bhasikoro, uye musoro wayo unowanzo mira uchidada nehurongwa hwekupfeka. Kana ngura yepamusoro painooneka kumusoro, gwapa rinoyerera richidzika nepanera, washer yekuisa chisimbiso inorasikirwa nekumanikidzana, uye mubatanidzwa unotanga kuchema.

lZinc electroplating (chena / yero / bhuruu passivated). The economic baseline. Yakajeka kana yero trivalent passivation inononoka chena ngura, uye 5-8 µm yezingi inopa angangoita 200-400 maawa kune chena ngura mukusarerekera munyu yekupfapfaidza bvunzo (ISO 9227 / ASTM B117). Inokodzera zvemukati uye yakadzivirirwa kunze.

lMechanical galvanizing. Zinc poda inotonhora-yakaiswa paburiro, ichivaka coating yakakora, yakagovaniswa zvakafanana (kusvika 40–55 µm) isina hydrogen embrittlement - yakakosha anti-corrosion mukana pane electroplating yeakaomeswa screws.

4. Mhedziso

Iyo self-drilling screw inomanikidza kuchera, kupinza uye kusungirira mukufamba kumwe chete, uye mukuita izvi yave iyo yechimiro uye isina mvura chisungo chinobata mahamvuropu esimbi emazuva ano pamwechete. Asi kukosha kwayo kweinjiniya chaiko kuri mukubatanidzwa kwezvivakwa zviviri: chibooreso chakaomeswa, chakakura zvakaringana chinoita gomba rakachena, uye nepamusoro-soro inorwisa-corrosion coating system inochengeta sikuru isina ngura kwehupenyu hwechivakwa. Sarudza siruu nekudhirowa simba, uye sarudza iyo yekupotera nemunyu-spray data - uye iyo yakazvininipisa screw ichapfuura pane pane yainobata pasi.
