15 Nzira dzekuziva Fake uye Shoddy Simbi

Mumaindasitiri umo kuchengetedzeka, kusimba, uye kunaka kwakakosha, kushandisasimbi chaiyohaisi nyaya yokungofarira—inotodiwa. Nehurombo, zvigadzirwa zvesimbi zvekunyepedzera uye zvisina mwero zviri kuwedzera kupinda mumusika, kunyanya muzvikamu zvekuvaka, zvekugadzira, uye zveinjiniya. Kushandisasimbi yemanyepo kana shoddyzvinogona kutungamirira kukukundikana kukuru, kukuvadzwa kwegadziriro, uye kurasikirwa nemari. Semutengesi akavimbika,sakysteelinotenda mukudzidzisa vatengi uye mainjiniya nezve nzira yekuona nekudzivirira isina kunaka-simbi. Muchikamu chino, tinonyora15 nzira dzinoshandakuziva simbi yekunyepa kana isingakodzeri nguva isati yakwana.

1. Tarisa Mamikira eMugadziri

Zvechokwadi zvigadzirwa zvesimbi zvinowanzove nazvozvidhindo zvakajeka, kusanganisira:

• Zita remugadziri kana logo

• Giredhi kana mwero (semuenzaniso, ASTM A36, SS304)

• Kupisa nhamba kana batch nhamba

Simbi yenhemakazhinji inoshaya zvicherechedzo zvakafanira kana kuratidza zvisingaenderane, zvakasvibiswa, kana zvisizvo.

2. Ongorora Surface Pedzisa

Zvigadzirwa zvesimbi zvechokwadi zvine ayunifomu, nzvimbo yakatsetsekaine controlled mill scale or coatings.

Zviratidzo zvesimbi isina kusimbazvinosanganisira:

• Nzvimbo dzakashata, dzine makomba, kana dzine ngura

• Uneven finishes

• Mitswe inooneka kana delaminations

At sakysteel, zvinhu zvose zvinoongororwa zvinoonekwa zvisati zvaitika.

3. Simbisa Dimensional Kururama

Shandisa calipers kana micrometer kuyera:

• Diameter

• Ukobvu

• Urefu

Simbi yenhemakazhinji inotsauka kubva pazviyero zvakatarwa, kunyanya mumutengo wakaderera rebar kana zvikamu zvezvimiro.

4. Kumbira Chitupa Chekuyedza (MTC)

Mutengesi ari pamutemo anofanira kupaEN 10204 3.1 kana 3.2 MTC, inotsanangura:

• Kemikari yakagadzirwa

• Mechanical properties

• Kurapa kwekupisa

• Testing results

Hapana chitupa kana magwaro ekunyepa mureza mutsvuku mukuru.

5. Ita Spark Test

Uchishandisa vhiri rekukuya, tarisa pfarivari dzinogadzirwa nesimbi:

• Carbon steel: Maspark akareba, machena kana yero

• Simbi isina ngura: Mhepo pfupi, tsvuku kana orenji ine kuputika kushoma

Zvisingaenderani spark mapataniinogona kuratidza kuti zvinyorwa hazvina kunyorwa zvisizvo kana kusanganiswa zvisizvo.

6. Ita Magnet Test

• Carbon steeline magnetic

• Austenitic simbi isina tsvina (304/316)kazhinji asiri magineti

Kana mhinduro yemagineti yesimbi isingaenderane negiredhi inotarisirwa, inogona kunge isiriyo.

7. Ongorora Huremu

Weresa hurefu hwakajairwa wohuenzanisa nehuremu hwedzidziso hunoenderana nekuwanda. Kutsauka kunogona kuratidza:

• Hollow kana porous zvikamu

• Giredhi yezvinhu zvisiri izvo

• Undersized dimensions

Simbi yechokwadi kubvasakysteelnguva dzose inowirirana neindasitiri kushivirira.

8. Ongorora Weldability

Simbi yekunyepera kana yakaderera-giredhi inowanzoita zvisizvo muwelding, zvichikonzera:

• Mitswe padyo nenzvimbo yeweld

• Kunyanya spatter

• Kupinda kusingawirirani

Yekuyedza diki weld inogona kufumura zvimiro zvakakanganisika mumasekonzi.

9. Tsvaga Inclusions uye Kukanganisa

Shandisa inotakurikaultrasonic test devicekana X-ray scanner yekutarisa:

• Mukati makatsemuka

• Slag inclusions

• Laminations

Kukanganisa uku kunowanikwa musimbi dzekunyepedzera kana dzakadzokororwa zvakare dzine hutsika husina kunaka.

10. Edzai Kuoma

Kushandisa ainotakurika kuomarara tester, simbisa kuti zvinhu zvinoenderana neyakaomeswa chiyero (semuenzaniso, Brinell kana Rockwell).

Hurema hwakaderera kana kukwira kugiredhi yakaziviswa zviratidzo zvekutsiva.

11. Ongorora Edge Hunhu

Genuine simbi zvigadzirwa vanemicheto yakachena, isina burrkubva pakuveura zvakanaka kana kukunguruka.

Simbi yekunyepa kana yakadzokororwa inogona kuratidza:

• Micheto yakakombama

• Kupisa ruvara

• Mativi akatsemuka kana akatsemuka

12. Ongorora Corrosion Resistance

Kana uri kubata nesimbi isina tsvina, ita amunyu spray kana vhiniga testpachikamu chidiki:

• Genuine stainless inofanira kuramba corrosion

• Fake stainless ichaita ngura mumaawa kana mazuva

sakysteelinopa corrosion-resistain stainless zvigadzirwa zvine kuteedzera kuzere.

13. Simbisa neThird-Party Lab Testing

Kana usina chokwadi, tumira muenzaniso kuneISO-certified test labzve:

• Spectrochemical analysis

• Tensile simba rekuedza

• Microstructure kuongorora

Kuzvimiririra verification kwakakosha kumapurojekiti makuru kana ane njodzi.

14. Tsvakurudza mukurumbira weMutengesi

Usati watenga:

• Simbisa zvitupa zvekambani (ISO, SGS, BV)

• Tarisa wongororo uye nhoroondo yekutengeserana

• Tsvaga ruzivo rwakasimbiswa uye kero yenzvimbo

Vasingazivikanwe kana vatengesi vasingatarisirwi vanozivikanwa masosi esimbi yokunyepera.

sakysteelmugadziri ane certified ane makore eruzivo rwekunze kwenyika.

15. Enzanisa Mutengo Wemusika

Kana mutengo wakapihwa urikure pasi kukosha kwemusika, zvingangonyanya kunaka kuti zviite chokwadi.

Vatengesi vesimbi dzemanyepo vanowanzokwezva vatengi nemitengo yakachipa asi vachiendesa zvinhu zvakaderera. Nguva dzose enzanisa makotesheni kubvamanyuko akavimbika akawanda.
