Xa usiva 'i-sustainable' kunye 'ne-flange bolts' kwisivakalisi esifanayo, abaninzi abantu abathengisayo bahlambalaza okanye baqale ukuthetha ngokuhlaziya isinyithi esilahliweyo. Lo ngumgibe oqhelekileyo-ucinga ukuzinza malunga nokuphela kobomi bezinto. Kodwa ukusuka emhlabeni ukuya phezulu, ekwenzeni nasekusebenziseni, kukho okungakumbi kuyo. Akunjalo nje ukuhlamba uhlaza; imalunga nokuba into emdaka ihlala ixesha elide phantsi koxinzelelo, isebenzisa amandla amancinci ukuyifaka, okanye ayifuni kutshintshwa yonke eminye iminyaka. Kulapho incoko yokwenyani kufuneka ibekho.

Izinto Ezinokukhethwa Ngokungaphaya Kokucacileyo

Wonke umntu utsibela kwi-stainless ukuxhathisa umhlwa, eyibiza ngokuba 'luhlaza' ukhetho. Kodwa ukuqina kwamandla okuvelisa i-austenitic ekumgangatho ophezulu, yithi i-316, inkulu. Ndiyibonile i-specs apho ibholiti yentsimbi yentsimbi yentsimbi eshushu-diphu, igqunywe ngokufanelekileyo, yenze umsebenzi kwindawo enobundlobongela obuphakathi iminyaka eli-15, kungekho mbilo. I-carbon footprint evela kwimveliso yayiphantsi ngokungathandabuzekiyo. I-innovation ayisoloko iyi-alloy entsha ethandekayo; ngamanye amaxesha imalunga nosetyenziso olukrelekrele kwezikhoyo. Siqhube ibhetshi yovavanyo yeprojekthi yosetyenziso lwaselunxwemeni, sifaka umgangatho we-A4-80 ngokuchasene nenkqubo yokwaleka ye-zinc-aluminiyam yeflake kwisiseko somgangatho ophantsi. Ezogqunyiweyo zibambe ngcono ngokuchasene nesitshizi setyuwa, kwaye ukusetyenziswa kobutyebi kukonke bekusezantsi. Ikwenza ukuba ubuze kwiinkcazo ezihlala zikhona.

Emva koko kukho ingxoxo yentsimbi ye-boron. Kuqhagamshelo lwe-flange yolwakhiwo olukumgangatho ophezulu, ukuya kwibanga le-10.9 okanye nakwi-12.9 nge-boron microalloying kuthetha ukuba unakho ukuthoba ibholithi okanye usebenzise ezimbalwa kuzo. Izinto ezincinci ngokudibeneyo. Kodwa inkqubo yonyango lobushushu ilambile ngamandla. Ngaba urhwebo lufanelekile? Siyibale kanye kwiprojekthi yeringi yesiseko se-injini yomoya. Ukusebenzisa ambalwa kodwa aphezulu-amandla I-Bolts Bolts ukunciphisa ubunzima bentsimbi bubonke malunga ne-8% kwiphakheji ye-fastener. Olu lugcino olubambekayo, kodwa kuphela ukuba inkqubo yokuvelisa iphuculwe. Ukuba isithando somlilo asisebenzi kakuhle, ulahlekelwa yinzuzo.

Ndikhumbula umthengisi, i-Handan Zitai Fastener Manufacturing Co., Ltd., esekwe kwesa siseko sikhulu semveliso saseYongnian eHebei, etyhala umgca “wokupholisa okulawulwayo” iibholiti zasemva kokufoja. Umbono yayikukufezekisa i-microstructure engcono ngaphandle kwenyathelo elongezelelweyo lokucima. Sazizama. Kwezinye iimeko, iipropati zomatshini zazingahambelani, kodwa xa zibetha uphawu, ukugcinwa kwamandla ngetoni kwakubonakala. Zezi nkqubo zohlengahlengiso, zihlala zivela kwiindawo ezinkulu zemveliso ezinje (ungajonga indlela yazo https //wwww.ziitasteners.com), ezibhabha phantsi kwerada kodwa zongeza.

IFactor yokuFakela ngokuSebenzayo

Uzinzo ayisiyobholi nje ebhokisini. Ziiyure zamadoda kunye nezixhobo zokubasa kwisiza. Ibholiti yeflange eyenzelwe ukulungelelaniswa lula kunye nokuqina ngokukhawuleza-njengazo zineewasha ezidibeneyo okanye ii-coatings ezisetyenzisiweyo zokulawula i-friction-inokunciphisa ixesha lokufakela ngesithathu. Bendikwimisebenzi yemibhobho apho abasebenzi bachitha ixesha elininzi bejijisana nemingxunya yebholiti engalungelelanisiweyo kunokoyikisa. Ukuqaliswa kwezinto ezintsha kukho kwijometri kunye neempawu zesibini. Ukuqala kwe-tapered kancinane kwimicu okanye ubuso obungena-symmetric flange bunokutshintsha umdlalo.

Siye salinga nge-polymer-based patch fastener, efakwe ngaphambili kwimicu. Bekufanele ukuba ibonelele ngokuthambisa kunye nokutywinwa, ukunciphisa imfuno yedope eyahlukileyo kunye nokuqinisekisa ukulayisha kwangaphambili okuchanekileyo. Ithiyori yayiqinile: ukulayishwa kwangaphambili okuchanekileyo kuthetha ukuba akukho kudlula ngaphezulu (amandla achithwayo) kunye netywina eliqinileyo, elihlala ixesha elide, ukuthintela ukuvuza kunye nokugcinwa kwexesha elizayo. Yinyani? Kwiindawo ezibandayo, i-patch yaba brittle ngexesha lokugcinwa. Isilele ngokumangalisayo kwindawo yasebusika eCanada. Buyela kwibhodi yokuzoba. Kodwa olo luhlobo lokungaphumeleli kwezandla ezikuxelela apho iingxaki zokwenyani ziphi.

I-torque-to-turn ratio ibaluleke ngaphezu kokuba abantu bevuma. I-coefficient egudileyo, engaguquguqukiyo ngakumbi yokukhuhlana kuthetha ukuba ufumana amandla obambezeleyo ayiliweyo kunye netorque engasetyenziswanga. Oko kuguqulela kwizixhobo ezincinci, ukudinwa kancinci kwabasebenzi, kunye negalelo elincinci lamandla. Ivakala incinci, kodwa yikale kumawaka oqhagamshelo kwinguqu yokucoca. Ukongiwa kwamafutha kwisixhobo se-torque ye-hydraulic kuphela kunokubaluleka. Leyo yinzuzo yokuzinza ngokuthe ngqo, kodwa awuyi kuyifumana kwingxelo ye-LCA.

Ukuqina kunye noMjikelo woLondolozo

Eyona bholithi izinzileyo yileyo ungaze uyitshintshe. Umhlwa lolona tshaba lukhulu. Ngaphaya kwemathiriyeli, iinkcukacha zoyilo njengeradiyasi yengcambu engqukuva ngokupheleleyo phantsi kwentloko yebholiti okanye inguqu engenamthungo ukusuka kwi-shank ukuya kwingcambu yomsonto inciphisa kakhulu indawo zokuxinanisa uxinzelelo. Ezi ziindawo zokudinwa. Ibholithi ehlutha ukudinwa ngaphambi kokuba igqwese kukungaphumeleli kabini-ulahlekelwa yingqibelelo edibeneyo kwaye uchithe amandla aqukiweyo kuloo ndawo.

Ndikhumbula ukuhlola uxhulumaniso lwe-flange kumgca wokucubungula imichiza emva kokuhamba kweminyaka emi-5. Iibholiti zentloko ze-hex eziqhelekileyo zibonise ukuthotywa okubalulekileyo kwentanda phantsi kwentloko. Ezo zinoyilo oluthinjiweyo, olusonta simahla lwewasha luhambe ngcono kakhulu. Iwasha inokuhlala kwaye igcine uxinzelelo lokutywina nanjengoko i-gasket icinezelwe, kwaye yaphula ikroba. Luyilo olukhokelela kuphuculo lokuqina. Yongeza iqhezu kwiindleko zeyunithi, kodwa iphelisa isiganeko sokugcinwa kwexesha elizayo. Yiloo calculus ebalulekileyo.

Emva koko kukho umba wokuhambelana kwegalvanic. Ukuncamathelisa ibholiti yentsimbi engatyiwayo kwiflange yentsimbi yekhabhoni? Ucela ingxaki ngaphandle kokuba uyigqume. Siye sahamba ngakumbi ekusebenziseni iibholiti zentsimbi ezigqunywe ngekhabhoni ezine-anode zokubingelela okanye iiwasha ezihlanganisiweyo ukophula isekethe. I-sexy encinci kunesisombululo se-monolithic alloy, kodwa ihlala isebenza ngakumbi kwaye i-resource-efficient ekuhambeni kwexesha. Utshintsho lukwinkqubo, hayi nje icandelo.

ULungiselelo kunye neNgingqi yokuFumana yaseKhaya

Le yinxalenye enkulu, ehlala ingahoywa yonyawo lonyawo. Iindleko zekhabhoni zokuthumela isikhongozeli esinzima I-Bolts Bolts ukusuka eAsia ukuya eYurophu okanye kuMntla Melika kukhulu. Uxinzelelo oluzinzileyo kukukhuthaza amaqela emveliso yengingqi. Indawo efana neYongnian eHebei, eTshayina, enothungelwano olushinyeneyo lwezityalo ezizigcinayo, ababoneleli ngemathiriyeli ekrwada, kunye nabacoci bobushushu, isebenza ngendlela emangalisayo ekuboneleleni ngeemarike zaseAsia nezengingqi. Kwiprojekthi ekuMazantsi-mpuma e-Asiya, ukukhangela ukusuka apho kunokuba lelona khetho lisezantsi-lilonke lempembelelo, zonke izinto ziqwalaselwe.

I-Handan Zitai Fastener, umzekelo, iqaqambisa uncedo lwayo lolungiselelo lokuba kufutshane neendlela zikaloliwe ezinkulu kunye nohola wendlela. Akunjalo nje intetho yokuthengisa. Ukuthunyelwa ngobuninzi ekhaya okanye kumazibuko akufutshane, oko kusebenza kunciphisa ukukhutshwa komlenze wothutho. Ukwenziwa kwezinto ezintsha apha kukulungelelaniswa kwekhonkco lonikezelo kwaye mhlawumbi nokufunyanwa kwemathiriyeli yengingqi. Ndibone ii-mill ziseta kufutshane kwezi ziseko zemizi-mveliso ukwenza mfutshane uhambo lwe-coil yentsimbi.

Icala le-flip lutyhalo olukufutshane nonxweme eYurophu nase-US. Ihlawuliswa ngokwezopolitiko, kodwa ngokwembono esulungekileyo yokuqina, inokufaneleka. Ngaba i-forge yasekhaya inokukhuphisana kwinkqubo yokusebenza kakuhle kwamandla kunye neplanti enkulu, edibeneyo e-Asia? Ngamanye amaxesha akunjalo. Kodwa ukuba ujonga kuncinci, amakhonkco obonelelo angaguquguqukiyo kunye nokukwazi ukwenza okuncinci, iibhetshi zangexesha ezinciphisa inkunkuma yoluhlu, umfanekiso wokuzinza uya kuba buthuntu. Akukho mntu uphendulayo. Ngoku senza iibhidi zemithombo emibini kwiiprojekthi ezinkulu, ezifuna uqikelelo lwekhabhoni evela phesheya kunye nababoneleli balapha ekhaya. Idatha imdaka, kodwa inyanzelisa umba.

Isetyhula: UkuSetyenziswa kwakhona kunye neNyaniso yokuphela koBomi

Masithembeke ngokukhohlakeleyo: uninzi lweebholiti ze-flange zolwakhiwo oluphezulu alusetyenziswanga kwakhona. Ziye zathotywa ukuze zivelise, okanye zidliwe, okanye zithathwa njengento enokutyiwa ngenxa yezizathu zokhuseleko. Iphupha loqoqosho olujikelezayo libetha eludongeni apha. Nangona kunjalo, kwezinye izinto ezingabalulekanga, ezinoxinzelelo oluphantsi, njengolwakhiwo oluthile lolwakhiwo okanye ukuyilwa kweemodyuli, siye savavanya amacebo okubuyisela umva ngeebholiti eziphawulweyo. Umngeni kukuhlolwa. Ukuqinisekisa njani ngokuthembekileyo ukuthembeka kwebholithi esetyenzisiweyo? Uvavanyo lwe-Ultrasonic lokwelula? Inokwenzeka, kodwa ixabiso lihlala ligqithise ixabiso elitsha lebholithi.

Eyona ndlela isebenzayo kukuyila ukuqhaqha. Ukusebenzisa iintlobo zebholithi ezingathandekanga kakhulu kwintambo yokugalela kunye nokubamba-njengazo zineengubo ze-molybdenum disulfide-yenza ukususwa kwexesha elizayo kunye nokusetyenziswa kwakhona okunokwenzeka ngakumbi. Sizibalule ezo bholithi zeprojekthi yenkqubo yemodyuli yokutyibilika. Ingcamango yayikukuba i-skids inokupheliswa, ihanjiswe, kwaye iphinde ifakwe kwisiza esitsha. Isebenzile, kodwa ngenxa yokuba inkqubo yogcino ibize ngokucacileyo ikhompawundi yokuchasana nokubamba ngexesha lofakelo kwakhona. Ngaphandle kolu qeqesho lusebenzayo, ukuveliswa kwezinto ezintsha kuyasilela.

Ekugqibeleni, ukurisayikilishwa. Yintsimbi ethe tye, kodwa iingubo ziyingxaki. I-Zinc, i-cadmium, i-polymer layers engqindilili-inokungcolisa umlambo we-scrap. Ukuya kufikelela kwezo zincinci, itekhnoloji yokwambatha ephucukileyo, okanye kungabikho nto yokugquma ngesiseko esingagugiyo, yenza ukuba isiphelo sobomi sicoceke. Yinkcukacha encinci, kodwa ivala i-loop. Ibholithi ekulula ukuyirisayikilishela, ngengqiqo engacacanga, izinzile. Kodwa le yindlela yokugqibela. Iinzuzo zokwenyani kukwenza ukuba ihlale ixesha elide kwaye isebenze ngcono kwasekuqaleni.

Ke, ngaba kukho iinguqulelo ezizinzileyo kwiibholithi zeflange? Ngokuqinisekileyo. Aziyiyo nje impumelelo ebambe intloko. Bakulwakhiwo lweenkozo zentsimbi, ijometri yengcambu yentambo, i-friction ye-coating, kunye nokusebenza kakuhle kwekhonkco lokubonelela. Kukusila, hayi uguquko. Kwaye umlinganiselo wempumelelo ayisosincamathelisi sesiqinisekiso; yibholithi ehlala iqinile, ayivuzi, kwaye iyalityalwa amashumi eminyaka. Oko kukusebenza okuzinzileyo kokugqibela.
