Kugwiritsa Ntchito Kwambiri

1. Maziko a Khoma la Pansi:Maziko a mulu wa nyumba zokhala ndi zipinda zambiri, mafakitale, nyumba zosungiramo katundu, nyumba zamalonda ndi nyumba zokhalamo (zoyenera mtundu uliwonse wa nyumba).

2. Maziko a Milu ya Mlatho:Maziko olimba a milatho yamisewu ikuluikulu, milatho ya sitima ndi milatho ya m'matauni; yoyenera milatho yosavuta, yopepuka, yokhazikika kapena yoyandama yomwe imadutsa mitsinje, nyanja ndi nyanja.

3. Kumanga Madoko:Maziko odalirika a malo osungiramo sitima, malo osungiramo sitima ndi malo osungiramo sitima, komanso malo osungiramo zida zolemera ndi katundu.

4. Mapulojekiti ndi Mainjiniya a Mphamvu ndi Mphepo Zapamadzi ndi Zapanyanja:Zinthu zopangidwa ndi mafakitale a m'nyanja ndi ma turbine amphepo a m'mphepete mwa nyanja, zomwe zimalimbana ndi mafunde, mafunde ndi dzimbiri la m'nyanja.

5. Mainjiniya Aakulu Onse:Milu yonyamula katundu wambiri yogwirira ntchito zazikulu zauinjiniya monga madamu, malo osungiramo zinthu pansi pa nthaka, ngalande, komanso makina amafakitale ndi katundu womangidwa.

Kulongedza ndi Kutumiza

1. Ma CD:

Matabwa kapena dunnage amagwiritsidwa ntchito pakati pa zigawo za matumba olongedza kapena zotengera kuti zisawonongeke panthawi yonyamula.

Kukonza pamwamba (ngati mukufuna): Utoto wakuda, mafuta oletsa dzimbiri, kapena mipukutu ya pulasitiki.

Milu ya galvanized yoviika m'madzi otentha ikhoza kuphimbidwa ndi filimu yoteteza kwakanthawi kuti isakhwime pamwamba.

Ma phukusi apadera akupezeka.

2. Mayendedwe:

Kutalika kwa masheya opindika: mamita 6, mamita 12. Kutalika kosakhala kwachizolowezi kumapezekanso ngati polojekiti ikufuna.

Yoyenera kuyenda panyanja, pa sitima, kapena pamsewu.

Nthawi yotumizira nthawi zambiri imakhala masiku 15-30 mutalandira malipiro, kutengera mtundu wa chinthu ndi zomwe zafotokozedwa.

Yoyenera kutumiza kunja padziko lonse lapansi, yokhala ndi zikalata zonse (satifiketi yotsimikizira kutsata malamulo, mndandanda wa zonyamula katundu, chikalata chonyamulira katundu).

3. Kusamalira Machenjezo:

Mangani mapaipi mosamala pogwiritsa ntchito crane kapena forklift yokhala ndi ma sling kapena ma sling kuti mupewe kusintha kwa zinthu.

Sungani mapaipi pamalo ouma, opumira mpweya, komanso ozizira musanawayike kuti apewe dzimbiri.

Kutumiza katundu wolemera kwambiri/wolemera kwambiri kuyenera kutsatira malamulo a mayendedwe am'deralo.

FAQ

1. N’chifukwa chiyani ASTM A500 ndi yoyenera kugwiritsa ntchito mapaipi okhala ndi maziko olimba?

ASTM A500 ndi chitoliro chachitsulo chopangidwa ndi chitsulo chozizira chokhala ndi kulekerera kolimba, chiŵerengero champhamvu kwambiri pakati pa kulemera, komanso magwiridwe antchito okhazikika, zomwe zimapangitsa kuti maziko azikhazikitsidwa bwino kuti pakhale zomangamanga zolemera.

2. Kodi pali kusiyana kotani pakati pa ASTM A500 Giredi B ndiGiredi C?

Giredi B: Mphamvu yocheperako yokolola ndi 42,000 psi (290 MPa), yoyenera kugwiritsidwa ntchito m'milu yodzaza ndi zinthu wamba.

Giredi C: Mphamvu yotsika kwambiri yokolola, mpaka 46,000 psi (317 MPa), mpweya wochepa kwambiri, woyenera ntchito zonyamula katundu wambiri, komanso wokhoza kulumikiza bwino.

3. Kodi pali kusiyana kotani pakati pa ASTM A500 ndi ASTM A252 pa maziko a nyumba?

A252 ndiye muyezo wokhazikika wa mulu wa mapaipi; A500 ili ndi zolekerera zolimba komanso malo osalala, zomwe zimapangitsa kuti ikhale yoyenera maziko otseguka, a m'madzi, komanso olondola.

4. Kodi milu yachitsulo ya A500 ingalumikizidwe m'munda?

Inde. Kulamulira kuchuluka kwa kaboni ndi manganese kumachepetsa kufanana kwa kaboni, kumaletsa kusweka kozizira, komanso kumathandiza kulumikiza pamalopo.

5. Ndi mitundu iti ya zophimba zotsutsana ndi dzimbiri zomwe zimayenera kugwiritsidwa ntchito m'madzi/malo owonekera?

Zosankha zitatu zazikulu: Mafuta a Balck, zokutira za 3PE, ndi zokutira za FBE, zoyenera kugwiritsidwa ntchito m'malo owononga a m'mphepete mwa nyanja/m'mphepete mwa nyanja.

6. Kodi mungathe kusintha momwe zinthu zilili malinga ndi zojambula za polojekiti?

Inde, titha kupereka: makulidwe akunja/khoma, kutalika kokhazikika kodulira, ma bevel, mbale zomaliza, maziko oyendetsera, ndi zonyamulira zonyamulira.

7. Ndi ziphaso ziti zabwino zomwe zimaperekedwa potumiza?

Timapereka satifiketi yoyesera zinthu ya EN10204 3.1 (MTC); timavomereza kuwunika kotumizidwa kuchokera ku mabungwe ena monga SGS/BV/TUV/DNV.
