Fiberglass Rock Bolt
Mafotokozedwe Akatundu
Nangula wa Fiberglass ndi chinthu chopangidwa ndi fiberglass chomwe nthawi zambiri chimapangidwa ndi ma fiberglass bundles amphamvu kwambiri ozunguliridwa ndi resin kapena simenti. Chimawoneka ngati chofanana ndi rebar yachitsulo, koma chimakhala chopepuka komanso cholimba kwambiri pakukana dzimbiri. Nangula wa Fiberglass nthawi zambiri amakhala ozungulira kapena opangidwa ndi ulusi, ndipo amatha kusinthidwa kutalika ndi m'mimba mwake kuti agwiritsidwe ntchito mwanjira inayake.
Makhalidwe a Zamalonda
1) Mphamvu Yaikulu: Ma nangula a fiberglass ali ndi mphamvu yabwino kwambiri yokoka ndipo amatha kupirira katundu wovuta kwambiri.
2) Zopepuka: Ma nangula a fiberglass ndi opepuka kuposa zitsulo zachikhalidwe, zomwe zimapangitsa kuti zikhale zosavuta kunyamula ndikuyika.
3) Kukana Kudzimbiritsa: Fiberglass siichita dzimbiri kapena dzimbiri, choncho ndi yoyenera malo onyowa kapena owononga.
4) Kuteteza: Chifukwa chakuti sizitsulo, ma fiberglass nangula ali ndi mphamvu zotetezera kutentha ndipo angagwiritsidwe ntchito pazinthu zomwe zimafuna kutetezera kutentha kwa magetsi.
5) Kusintha kwa Makonda: Ma diameter ndi kutalika kosiyana kungatchulidwe kuti kukwaniritse zofunikira za polojekiti inayake.

Ubwino wa Zamalonda
1) Kulimbitsa kukhazikika kwa nthaka ndi miyala: Ma nangula a fiberglass angagwiritsidwe ntchito kulimbitsa kukhazikika kwa nthaka kapena miyala, kuchepetsa chiopsezo cha kugwa kwa nthaka ndi kugwa.
2) Kapangidwe Kothandizira: Kawirikawiri imagwiritsidwa ntchito pothandizira zomangamanga monga ngalande, zofukula, zigwa ndi ngalande, zomwe zimapatsa mphamvu ndi chithandizo chowonjezera.
3) Kumanga pansi pa nthaka: Ma nangula a fiberglass angagwiritsidwe ntchito m'mapulojekiti omanga pansi pa nthaka, monga ngalande zapansi panthaka ndi malo oimika magalimoto pansi pa nthaka, kuti atsimikizire chitetezo ndi kukhazikika kwa polojekitiyi.
4) Kukonza Dothi: Ingagwiritsidwenso ntchito m'mapulojekiti okonza nthaka kuti iwonjezere mphamvu ya nthaka yonyamula.
5) Kusunga ndalama: Ikhoza kuchepetsa mayendedwe ndi ndalama zogwirira ntchito chifukwa cha kulemera kwake kopepuka komanso kuyika kosavuta.
Kugwiritsa Ntchito Mankhwala
Nangula wa Fiberglass ndi chinthu chogwiritsidwa ntchito kwambiri pa ntchito zosiyanasiyana, chomwe chimapereka mphamvu yodalirika komanso kukhazikika pamene chimachepetsa ndalama zomwe zimagwiritsidwa ntchito. Mphamvu yake yayikulu, kukana dzimbiri komanso kuthekera kosintha zinthu mwamakonda zimapangitsa kuti chikhale chotchuka pa ntchito zosiyanasiyana.
