Ukuba zigcinwe kwindawo eyomileyo, yangaphakathi kude nezinto ezibolayo, iibholiti ze-10.9S zinokuhlala ngokungenasiphelo. Nangona kunjalo, ukuba ziqatywe nge-oyile yokukhusela okwethutyana, le oyile inokwehla kwiminyaka emininzi. Kunconywa ukuba uhlolisise iibholiti zokugqwala okanye ukuchithwa kwengubo ngaphambi kokusetyenziswa ukuba zigcinwe iminyaka engaphezu kwe-2-3. Ukupakishwa okufanelekileyo kunye nolawulo lwemozulu lwandisa ukusetyenziswa kwabo kakhulu.

Ngaba iibholiti ze-10.9S ziyahambelana neepleyiti zentsimbi?

Ewe, kodwa kufuneka kuqwalaselwe ngokukhethekileyo. Ukuba usebenzisa iibholithi ezishushu zediphu, imisonto yamandongomane kufuneka icofe ngokugqithisileyo ukuze ilingane nengubo ejiyileyo. Ukongezelela, i-coefficient of friction change with galvanization, ngoko ke ixabiso lokufakela i-torque kufuneka lihlengahlengiswe ngokusekelwe kwiimvavanyo zokulinganisa imihla ngemihla ukuqinisekisa ukuba ukulayishwa kwangaphambili okuchanekileyo kuphunyeziwe ngaphandle kokugxininisa ibholt.

Ukuqukumbela kunye neNgcebiso yokuFumana iQhinga

I 10.9S Ulwakhiwo lweNsimbi yeBanga eNkulu ene-Hexagonal Bolt Ihlala ingumqolo wolwakhiwo olunzima lwangoku, olunikezela ngolungelelwaniso olungenakuthelekiswa nanto lwamandla, i-ductility, kunye nokuthembeka. Njengoko sijonge ku-2026, imarike iya kuqhubeka ukubeka phambili uqinisekiso lomgangatho kunye nokulandelelwa ecaleni kwamaxabiso okhuphiswano. Kubathathi-nxaxheba beprojekthi, ukuqonda ukungafani okungafaniyo kwiipropati zoomatshini, iiprothokholi zofakelo, kunye nabaqhubi beendleko kubalulekile ekuphunyezweni kweprojekthi ngempumelelo.

Kwiinjineli kunye nabaphathi bokuthengwa kwempahla, eyona nto iphambili kukubeka phambili intsebenziswano ngqo efektri ezibonisa iziqinisekiso ezicacileyo zeEEAT. Khangela ababoneleli ababonelela ngeZiqinisekiso ezibanzi zoVavanyo lweMill, babambelele kwimigangatho yamazwe ngamazwe njenge-GB/T kunye ne-ISO, kwaye babe nerekhodi eqinisekisiweyo yokubonelela ngeeprojekthi zeziseko ezingundoqo. Kuphephe ukuyekelela kumgangatho wezinto eziphathekayo zokonga iindleko ezingephi, njengoko umngcipheko wokungaphumeleli kolwakhiwo uyodlula lee izibonelelo zokuthengwa kwempahla.

Ngubani ofanele asebenzise esi sikhokelo? Olu lwazi lulungiselelwe iinjineli zezakhiwo, abaphathi beprojekthi yokwakha, iingcali zokuthengwa kwempahla, kunye nabaqulunqi ababandakanyeka kwiiprojekthi zentsimbi enzima. Nokuba uyila ibhulorho entsha okanye izixhobo zokukhangela umzi-mveliso, ukuqinisekisa ukuba iziqhoboshi zakho ziyahlangabezana nemigaqo ye-10.9S linyathelo elingaxoxisiyo elibhekiselele kukhuseleko kunye nokuqina.

Amanyathelo Alandelayo: Xa ulungiselela ithenda yakho elandelayo okanye iodolo yokuthenga, cela amaxwebhu aneenkcukacha zobugcisa kunye neengxelo zovavanyo lwesampulu kubaboneleli abanokubakho. Qinisekisa umthamo wabo wemveliso kunye neenkqubo zokulawula umgangatho. Ngokusebenzisa ulwazi malunga neentsingiselo zamaxabiso zika-2026 kunye neenkcukacha zobugcisa ezinikezelwe apha, unokwenza izigqibo ezinolwazi eziphakamisa zombini iindleko kunye nokusebenza kolwakhiwo.
