Ntchito Yaikulu

1. Maziko a Khoma la Pansi:Maziko ozama a nyumba zazitali, mafakitale, nyumba zosungiramo katundu, nyumba zamalonda ndi nyumba zokhalamo. Maziko ozungulira (oyenera mitundu yonse ya nyumba).

2. Maziko a Milu ya Mlatho:Maziko onyamula katundu a milatho yamisewu ikuluikulu, milatho ya sitima, ndi misewu yodutsa m'matauni. Ikani maziko a milatho yodutsa mitsinje, nyanja, ndi milatho yowoloka nyanja.

3. Kumanga Madoko:Maziko onyamula katundu wa malo oimikapo doko, malo osungiramo sitima, ndi malo oimikapo doko. Zipangizo zolemera ndi malo osungira katundu wa doko.

4. Mapulojekiti a Mphamvu ya Mphepo ya M'nyanja ndi Uinjiniya wa Zam'madzi:Maziko a ma turbine amphepo akunyanja. Kapangidwe kothandizira mapulatifomu akunyanja, mapaipi akunyanja, makoma a nyanja, ndi zina zotero. Kukana mafunde, kukana mafunde, ndi kukana dzimbiri la m'nyanja.

5. Uinjiniya Waukulu Wanyumba:Maziko akuya okhala ndi milu yayikulu ya mainchesi a ntchito zazikulu zauinjiniya (monga madamu, malo osungiramo zinthu pansi pa nthaka, ndi ngalande). Thandizo la makina amafakitale ndi katundu womangidwa.

Kulongedza ndi Kutumiza

Phukusi 1:Ma bandeji achitsulo kuti agwire mosavuta. Mabuloko a matabwa kapena dunnage amayikidwa pakati pa milu kuti apewe kusuntha kwa ziwalo panthawi yonyamula. Kukonza pamwamba (ngati mukufuna): Kupaka utoto wakuda, mafuta oletsa dzimbiri, filimu ya pulasitiki. Milu ya galvanized yoviika m'madzi otentha ikhoza kuphimbidwa ndi filimu yoteteza kwakanthawi kuti ipewe kukanda pamwamba. Mapaketi okonzedwa mwamakonda angaperekedwe.

2 Kutumiza:Kutalika kwa katundu wamba: 6m, 12m. Kumapezeka muutali wapadera. Kumabwera ndi Sitima Yapamadzi ndi Msewu Woyenera mayendedwe apanyanja, sitima kapena pamsewu. Nthawi yotumizira nthawi zambiri imakhala masiku 15-30 mutalandira malipiro, kutengera kuchuluka ndi zomwe zafotokozedwa. Yoyenera kutumiza kunja padziko lonse lapansi, yokhala ndi chikalata chokwanira (satifiketi yowunikira, mndandanda wolongedza, bilu yonyamula katundu).

3 Malangizo Othandizira:Musagwiritse ntchito zingwe kapena zingwe zopanda ma pad kuti zigwire ntchito mwachindunji pamwamba pa chitoliro kuti chitolirocho chisawonongeke. Sungani pamalo ozizira, ouma komanso opumira bwino, pewani dzimbiri musanayike. Kutumiza kwakukulu komanso kolemera kwambiri chonde tsatirani malamulo a m'deralo otumizira katundu.

FAQ

Q1: Kodi ndi chiyaniMulu wa chitoliro chachitsulo cha ASTM A252?
Ndi chitoliro chachitsulo chomwe chimagwiritsidwa ntchito pobowola, maziko, milatho, malo osungiramo zinthu, ndi malo omanga.

Q2: Kodi magiredi omwe alipo ndi ati?
Giredi 1, 2, ndi 3 - Gr.1 imagwiritsidwa ntchito ponyamula zinthu mopepuka, Gr.2 imagwiritsidwa ntchito pomanga nyumba zonse, Gr.3 imagwiritsidwa ntchito kwambiri pouma.

Q3: Kodi muli ndi kukula kotani?
Ma diameter: 4"–24" (114–610mm)

Kutalika: 6–12m kapena malinga ndi zomwe mukufuna

Q4: Kodi milu iyi imapakidwa utoto?
Inde - Yoviikidwa ndi Galvanized, Yopakidwa Epoxy kapena Yopakidwa utoto kuti iteteze dzimbiri.

Q5: Ndi mtundu wanji wa satifiketi womwe umaperekedwa?
Milu yonse kuphatikizapo kuyang'aniridwa ndi MTC ya chipani chachitatu ikupezeka.

Q6: Kodi milu imatumizidwa bwanji?
Zomangidwa ndi zingwe zachitsulo
Kutumiza katundu wambiri kapena mapaleti amatabwa.
Ndi zipewa zomaliza komanso mankhwala oletsa dzimbiri

Q7: Kodi ndingapeze kukula koyenera?
Inde, tikhoza kukupatsani ma diameter, kutalika ndi ma grade apadera a polojekiti yanu.

Q8: Kodi mungasankhe bwanji giredi yoyenera?
Kutengera mphamvu ya katundu, momwe nthaka ilili komanso momwe imagwiritsidwira ntchito pomanga. Thandizo kuchokera kwa mainjiniya.

Q9: Kodi nthawi yotumizira nthawi zambiri imakhala yotani?
Masiku 15-30, kutengera kuchuluka ndi kusintha kwa zinthu.
