Steel npawt nhpang ni a matu Self-Drilling Screws ni hpe lata la na matu lam matsun: Nta ntsa hka lim ai hte hka lim ai hpe gara hku koi lu na
Steel hte galaw ai hte magri nta ntsa hta, self-drilling screws ni gaw kaji tim, nta ting a asak hpe dawdan ya ai. Contractor law law gaw, mari ai shaloi manu hpe sha myit maju jung nna, drill point matching, coating n-gun n-rawng ai, washer a ngang grin ai lam zawn re ai ahkyak ai lam ni hpe n myit mada ai.
Shut ai fastener hpe lata ai a akyu gaw grai sawng ai:
Leaking: EPDM washer ni gaw shata loi mi laman hta n-gun yawm mat ai (sh) hten za mat ai.
Stripping: Screw gaw n-gang kata de n shang lu ai majaw, manu dan ai hku gawgap na matu aten la ra ai.
Rusting: Standard zinc plating gaw panglai hkin-gau makau grup yin hta hka lim ai hpe n dang hkam lu ai.
Mahkrum madup nga ai fastener galaw ai wa langai hku nna, n-gang n-gun, grup yin masa ni, n-gun rawng ai arung arai ni hpe madung tawn nna, hkum tsup ai self-drilling screw hpe lata la na matu ndai laika buk hpe anhte shinggyin la ga ai.
1. Steel n-gun a matu "Drill Point" hpe lata la u.
Ndai gaw ndai hpaga lam hta grau nna shut ai lam rai nga ai. Self-drilling screw a drill point (sh) n-gup gaw drill bit zawn galaw nna, nang gyit da ai n-gang a n-gun hte bung ra ai.
#3 Htu shara: 1.0mm - 3.0mm n-gun n rawng ai n-gang n-gang ni a matu htuk manu ai. Ndai gaw grau nna lang ai amyu rai nna, n-gun n law ai nlung npawt ni hte nta ntsa gap na matu lang ai.
#4 Htu shara: 3.0mm - 5.0mm lapran - galu ai n-gang n-gang ni a matu htuk manu ai.
#5 Htu shara: 5.0mm - 12.0mm n-gun ja ai n-gang n-gang ni a matu htuk manu ai.
Hpaji ninghkring ni a hpaji jaw ga: 2.5mm n-gun n rawng ai n-gang ntsa #5 drill point lang yang, screw gaw n-gang kata de n-htum mat na re. De a malai, npu kaw "skid" galaw nna, drill point hpe jahten kau ya ai katsi ai hpe shabyin ya nna, n-gun n rawng hkra pat shingdang kau ya na re.
2. Na a grup yin hte hkrak ai Surface Coating hpe lata la u .
Screw a "jacket" gaw kade daram na hkra hkam sharang na hpe dawdan ya ai. Ndai kaw gaw, n-gun rawng ai coatings ni hpe shingdaw yu ga:
.
| Hpun kap ai amyu | Hka garan ai chyam dinglik ai lam (ASTM B117) | Hpaji jaw ai Application | Jahpu manu hkrat ai |
|---|---|---|---|
| Hpraw/Hpraw Zinc | 24 - 48 Hkying hkum | Nta kata, hkyet mat ai grup yin | Nyem ai |
| Hpraw ai Zinc | 72 - 96 Hkying hkum | Shinggan de lang ai | Myi htoi |
| Dakromet | 500 - 1000+ Hkying hkum | Chemical hkai sun ni, panglai hkin-gau ginra ni | Tsaw ai |
| Ruspert | 1000+ Hkying hkum | Grai sawng ai grup yin | Pahkam gumhpraw |
Myit yu na lam: Hka hkin gau makau na sutdek ni (sh) tsi rung ni a matu, Dacromet (sh) Ruspert coatings ni hpe grai tsun shadut ga ai. Ndai masa hta, shata kru laman, standard galvanized screw ni gaw, n-gun n rawng nna, "hka hpraw" pru wa na re.
3. EPDM Washers: Hka lim ai hpe ninghkap na matu hpang jahtum na makawp maga lam
Manu n-htuk ai screw law law gaw UV nhtoi npu hta asak kaba nna ngang kang wa ai standard rubber washer ni hpe lang ma ai.
-Hpaji rawng ai EPDM: Anti-UV n-gun rawng ai arung arai ni lawm ra ai. 120℃katsi ai hte -40℃katsi ai hpe n-htum hkra hkam sharang lu ra ai.
Vulcanization: Kaja ai washer hpe n-gun dat ai shaloi n hkrat hkra, magri washer hte n-gun dat (bond) galaw da ai.
Color Matching: Standard hpraw hta lai nna, anhte gaw RAL nsam-htuk manu ai washers (ga shadawn, Dark Green, White) hpe jaw ai, dai gaw na a nta ntsa hte n-gun n rawng ai sha, manu dan ai nsam hpe lu la na matu re.
4. Masha law malawng shut ai lam ni & Case Studies ni
Shut ai lam: 5mm n-gang n-gang ntsa #3 drill point lang ai.
Mahtai: Screw gaw hka htung kata de n-gun rawng mat ai. Dai hpe n mai shaw kau ai, re-drilling galaw ra ai hte bungli galaw ai ni hpe jahten kau ra ai.
Shut ai lam: Acidic nga ai shara ni hta Blue/White Zinc screw ni hpe lang ai.
Mahtai: Shata 3 laman Red rust pru wa ai majaw, nta ntsa hka lim ai majaw customer ni claim byin wa ai.
Shut ai lam: N-gun n law ai sheet screw ni hta -torque n-gun kaba ai driver hpe lang ai.
Hpang jahtum: Dai hkra machyi ai lam gaw thread ni hpe gang je kau ya ai (sh) EPDM washer hpe gang je kau ya ai. Clutch- hpe gram lajang da ai drill hpe lang na matu anhte hpaji jaw ga ai.
5. Summary: Gara hku lawan ai hku Order galaw na?
Kaja dik ai quote hte hkrak ai product hpe lu la na matu lawu na shiga ni hpe jaw u:
Thickness: Nang htu ai steel sheet a thickness kade daram rai na kun?
Hkringmang daju: Bungli masing gaw lamu ga kata, panglai makau (sh) jak rung makau kaw rai kun?
Color: RAL color langai hte bung hkra screw baw ra ai kun?
Galoi mung san ai ga san ni (FAQ)
Q1: Tinang hkum tinang -htu ai hte tinang hkrai -htu ai screw ni gaw hpa shai ai kun?
A: Self-drilling screw ni hta pilot hka htung n lawm ai sha, n-gang hpe hkrak shang lu ai hka htung nga ai. Self-tapping screw ni hpe n bang shi yang, shawng -htu tawn da ai hka htung ra ai.
Q2: EPDM washer gaw quality kaja ai hpe gara hku chye lu na kun?
A: Loi ai chyam dinglik ai lam gaw 100℃hka lum ai hpe chyam dinglik ai lam re. EPDM gaw hkying hkum 2 tup hka ja ngut ai hpang mung elastic naw rai nga ai, 劣质 rubber gaw n-gun n rawng ai (sh) n-gun n rawng mat na re.
Q3: Test galaw na matu sample ni hpe jaw ai kun?
A: Rai sai. Anhte gaw, manu jahpu n jaw ra ai sha, masat da ai masat da ai lam ni hpe (ga shadawn, #14 x 1") jaw ai majaw, law law hpe n bang shi yang, na a bungli shara kaw chyam yu mai ai.
