Imfihlo yokuthintela izikrufu zodonga lwekhethini ukuba zingavuzi: Khetha izikrufu ezichanekileyo ezingama-316 zentsimbi engenakutyiwa, yonga ixhala kunye nemali!

Kutheni udonga lomkhusane luqala ukuvuza emva kweminyaka embalwa?

Iiprojekthi ezininzi zodonga lwamakhethini zilungile xa zigqityiwe, kodwa ziqala ukuvuza emva kweminyaka embalwa. Enyanisweni, i-80% yokuvuza iqala kwimingxuma yezikrufu! Izikrufu eziqhelekileyo zentsimbi engatyiwayo ziyathanda ukuba nomhlwa kwindawo efumileyo, engaselwandle okanye engcoliseke kakhulu. Emva kokugqwala, umthamo uyanda, nto leyo ebangela ukuba i-sealant iqhekeke, kwaye amanzi emvula aya kungena nge-screws.

Uthini umahluko phakathi kwe-304 kunye ne-316 yezikrufu zensimbi ezingenasici?

Abantu abaninzi bacinga ukuba izikrufu zentsimbi estainless steel ziyafana, kodwa eneneni i-316 iyakwazi ukumelana nomhlwa kune-304, ngakumbi kwiindawo ezithanda ukuba nomhlwa ezifana nolwandle kunye neendawo zoshishino:

1. I-304 insimbi engenasici: Akukho ngxaki yokusetyenziswa kwemihla ngemihla, kodwa elwandle okanye kwizixeko ezingcoliseke kakhulu, inokugqwala kwiminyaka eyi-3-5.

2. I-316 insimbi engenasici: Yongeziweyo "molybdenum", inokumelana nokugqwala okunamandla kwaye ingasetyenziselwa iminyaka engaphezu kwe-10 kwindawo efanayo.

Kutheni le nto izikrufu zentloko yentsimbi engama-316 zingenakuvuza ngakumbi?

1. Izinto ezingcono: usebenzisa i-real 316 insimbi engenasici (ingxelo yovavanyo lwezinto eziphathekayo inokubonelelwa), ehlala ixesha elide kunezikrufu eziqhelekileyo.

2. Ukutywinwa okungcono: Intloko ye-screw ine-gasket yerabha, enokuthi icinezelwe emva kofakelo ukunqanda amanzi ukuba angangeni kwi-screw hole.

3. Ufakelo oluzinzile ngakumbi: uyilo olukhethekileyo lwentambo, aluyi kulimaza i-aluminium xa iqinisa, kwaye ayiyi kukhulula emva kokusetyenziswa kwexesha elide.

Imeko yokwenyani: Kutheni amaqela obunjineli etshintshela kwizikrufu ezingama-316?

Ingxelo evela kwiinkampani ezininzi zobunjineli bodonga lwamakhethini esiye sisebenzisane nazo:

Iiprojekthi ezazisetyenziselwa ukusebenzisa izikrufu ze-304 zaqala ukulungiswa emva kweminyaka emi-3-5, kwaye kubiza imali eninzi ukulungisa ixesha ngalinye.

Emva kokutshintsha kwii-screws ze-316, kwakungekho ngxaki yokuvuza iminyaka eyi-8-10, eyasindisa ingxaki yokulungiswa kamva.

Unokukhetha njani izikrufu ezikufanelayo?

1. Izixeko eziqhelekileyo (umoya ongcono): 304 izikhonkwane zensimbi ezingenasici + sealant.

2. Iindawo ezingaselwandle/zemizi-mveliso (kulula ukurusa): Qiniseka ukuba usebenzisa izikrufu zentsimbi engatyiwayo ezingama-316 ezinegaskhi ezingangeni manzi.

3. Izakhiwo eziphezulu eziphezulu / ezibalulekileyo: Kucetyiswa ukuba kusetyenziswe izikrufu ze-316 + i-fluorocarbon coating, ekwazi ukumelana nokuguga kwe-UV.

Kutheni ukhetha thina?

1. Ubonelelo oluthe ngqo lwefektri: akukho bantu baphakathi, ixabiso elingcono, kunye nomgangatho olawulekayo.

2. Inkxaso yokwenza ngokwezifiso: iinkcukacha ezahlukeneyo, ubude, kunye nonyango lomphezulu (njengokugquma, ukugquma).

3. Ukuhanjiswa ngokukhawuleza: Iimpawu eziqhelekileyo zithunyelwa kwiiyure ze-72, kwaye ii-odolo eziphuthumayo zinokukhawuleza.
