Imfihlo yokuvimbela izikulufu zodonga lwamakhethini ukuthi zingavuzi: Khetha izikulufu zensimbi engagqwali ezingu-316 ezifanele, yonga ukukhathazeka nemali!

Kungani udonga lwamakhethini luqala ukuvuza ngemva kweminyaka embalwa?

Amaphrojekthi amaningi odonga lwamakhethini alungile lapho esanda kuqedwa, kodwa aqala ukuvuza ngemva kweminyaka embalwa. Eqinisweni, ama-80% okuvuza aqala emigodini yesikulufu! Izikulufu zensimbi engagqwali ezijwayelekile zijwayele ukugqwala ezindaweni ezinomswakama, ogwini lolwandle noma ezingcoliswe kakhulu. Ngemva kokugqwala, ivolumu iyakhula, okwenza i-sealant iqhekeke, futhi amanzi emvula azongena ngezikulufo.

Uyini umehluko phakathi kwezikulufu zensimbi engagqwali ezingama-304 nezingu-316?

Abantu abaningi bacabanga ukuthi izikulufu zensimbi engagqwali ziyefana, kodwa empeleni i-316 ikwazi ukumelana nokugqwala kune-304, ikakhulukazi ezindaweni ezivame ukugqwala njengasolwandle kanye nezindawo zezimboni:

1. 304 insimbi engagqwali: Ayikho inkinga ukusetshenziswa nsuku zonke, kodwa ngasolwandle noma emadolobheni angcoliswe kakhulu, kungase kugqwala eminyakeni 3-5.

2. 316 insimbi engagqwali: Kwengezwe into ethi "molybdenum", inokumelana nokugqwala okuqinile futhi ingasetshenziswa iminyaka engaphezu kweyi-10 endaweni efanayo.

Kungani izikulufu zethu ezingu-316 zensimbi engagqwali zingavuzi kakhulu?

1. Izinto ezingcono: kusetshenziswa insimbi engagqwali engu-316 yangempela (unganikezwa umbiko wokuhlola), okuhlala isikhathi eside kunezikulufu ezijwayelekile.

2. Ukuvala okungcono: ikhanda lesikulufu line-gasket yerabha, engacindezelwa ngemva kokufakwa ukuze kuvinjwe amanzi ukuthi angangeni embobeni yesikulufu.

3. Ukufakwa okuzinzile: umklamo okhethekile wentambo, ngeke kulimaze i-aluminium lapho iqinisa, futhi ngeke ikhululeke ngemva kokusetshenziswa isikhathi eside.

Icala langempela: Kungani amaqembu onjiniyela eshintshela kuzikulufu ezingama-316?

Impendulo evela ezinkampanini eziningi zobunjiniyela bezindonga zamakhethini esibambisene nazo:

Amaphrojekthi ayesebenzisa izikulufu ezingu-304 aqala ukulungiswa ngemva kweminyaka engu-3-5, futhi kubiza imali eningi ukulungisa isikhathi ngasinye.

Ngemva kokushintshela kuzikrini ezingu-316, akuzange kube khona inkinga yokuvuza iminyaka engu-8-10, okwasindisa inkinga yokulungiswa kamuva.

Ungakhetha kanjani izikulufu ezifanelana nawe?

1. Amadolobha avamile (umoya ongcono): 304 izikulufo zensimbi engagqwali + sealant.

2. Izindawo ezisolwandle/zezimboni (okulula ukugqwala kuzo): Qiniseka ukuthi usebenzisa izikulufu zensimbi engagqwali ezingu-316 ezinamagasket angangeni manzi.

3. Izakhiwo eziphakeme kakhulu/ezibalulekile: Kunconywa ukusebenzisa izikulufu ezingu-316 + okokunamathela kwe-fluorocarbon, okumelana kakhulu nokuguga kwe-UV.

Kungani ukhethe thina?

1. Ukunikezwa okuqondile kwasefekthri: abekho abaphakathi, intengo engcono, nekhwalithi elawulekayo.

2. Ukwesekwa ngokwezifiso: ukucaciswa okuhlukahlukene, ubude, nokwelashwa kwendawo (okufana nokucwenga, ukunamathela).

3. Ukulethwa okusheshayo: Ukucaciswa okujwayelekile kuthunyelwa emahoreni angama-72, futhi ama-oda aphuthumayo angasheshiswa.
