Ukuqina kwe-zinc egcwele i-gasket enemibala? 

Makhe sinqumle i-fluff yokuthengisa. Xa umntu ebuza malunga nokuqina kwe-a I-zulthi enemibala ye-xes, badla ngokufanekisela loo nto intle eluhlaza okwesibhakabhaka, etyheli, okanye emnyama ebambelele ngonaphakade. Ukujonga okwenyani: umbala udla ngokuba lelona khonkco libuthathaka. Ayisiso isikrweqe somlingo; yingubo engaphezulu kwesiseko se-zinc, kwaye iindlela zayo zokungaphumeleli zichanekile kwaye, kumava am, zihlala zingaqondwa kakuhle kwii-procurement specs.

Umbono ongeyiyo ongundoqo: Umbala njengoMsebenzi

Ndibone imizobo emininzi kakhulu ebiza nje i-zinc gasket eluhlaza, ecinga ukuba umbala ngokwawo ubonisa ibakala eliphezulu lokuxhathisa umhlwa. Akunjalo. Isiseko sihlala siyi-zinc plating-ngokuqhelekileyo iblue iridescent chromate conversion coating phezu koko. Umbala uvela kwidayi okanye kunyango lwesibini olufakwe kula maleko ane-porous chromate. Ke, ukuqina kuqhekeka kube ngamadabi amabini: ukhuselo lwezinki lokutya, kunye nokumelana nombala wombala, i-UV, kunye nokuvezwa kwemichiza.

Apho kukho inkohliso kukuhlangana. Umsebenzi oqinisa ibholithi, okanye igasket ehlikihla kwindlu ngexesha lofakelo, unokukrwela ngokulula loo maleko anombala. Ngequbuliso, unendawo ecwebezelayo yesilivere apho isiseko sezinc sivezwa khona. Ayikokusilela kokukhuselwa kwe-corrosion okwangoku, kodwa ibonakala ngathi enye, kwaye i-aesthetics ibalulekile kwizicelo ezijongene nabathengi. Ndikhumbula ibhetshi yezinki ezimnyama ezifakwe igaskets zeflange kwindawo ebiyelweyo yombane yangaphandle apho abafakeli besebenzisa abaqhubi bamandla. Umnxibelelanisi wesokethi wawunxibe amakhonkco kumgca omnyama kanye kwizihlalo zentloko yebholt phambi kokuba iyunithi ibone imvula. Umxhasi wayengonwabanga malunga nenkangeleko yangaphambili.

Iziphumo zovavanyo lwesitshizi setyuwa zibalisa ibali elintsonkothileyo. Ichromate eluhlaza okwesibhakabhaka ngaphezulu kwe-zinc inokubetha iiyure ezingama-96 ukuya kumhlwa omhlophe. Iinguqulelo ezinemibala, ngakumbi ezimnyama ezinje nge-drab emnyama okanye yomnquma, zinokubonisa ukufiphala kombala okanye amabala nakwangaphambili, nangona i-zinc engaphantsi isasebenza. Ukuba i-spec yakho ikhathalela kuphela umhlwa obomvu, ulungile ixesha elide. Kodwa ukuba ingqibelelo yombala yinxalenye yespekthi yemveliso-yokufaka ikhowudi okanye ukubeka uphawu-usele usilele.

Iinyani zokusiNgqongileyo vs. Amabango eKhathalogi

Ulibale ilebhu. Makhe sithethe ngendawo yenjini eshushu, efumileyo, okanye isakhiwo sangaphandle esikufuphi nonxweme. Ukubonakaliswa kwe-UV kukubulala idayi eziphilayo. Obu bluwu bukhazimlayo kwiwasha enepleyiti yesibiyeli selanga bunokujika ubisi, obuluhlaza obuluhlaza obumdaka ngetshova ngexesha elinye. Ikhromati engaphantsi yenza umsebenzi wayo, kodwa into ebonakalayo ayisekho. Ukubonakaliswa kwemichiza lelinye irhamncwa. Ndikhe ndabona iigaskets ezinemibala ebomvu ye-zinc esetyenziswa koomatshini apho ngamaxesha athile isitshizi solwelo lwehydraulic sijike umbala ube bubumdaka, obupinki. Ulwelo aluzange luhlasele i-zinc, kodwa lunyibilikise idayi.

Apha kulapho ukhetho lwezinto eziphathekayo lukuluma khona. A I-zulthi enemibala ye-xes isoloko ikhethwa njengenye indlela engabizi kakhulu kwintsimbi engatyiwayo okanye i-hot-dip galvanizing kwindawo ephakathi. Kodwa ukumodareyitha ngundoqo. Kwiphaneli eyomileyo, yangaphakathi apho ubukhulu becala yeyokuchongwa? Ukhetho oluhle kakhulu. Ngayo nayiphi na into enokucondensation, ukukhwela ibhayisekile rhoqo, okanye ukonakala, ukwixesha elibolekiweyo. Umthi wesigqibo akufuneki uqalise ngokufuna eluhlaza okwesibhakabhaka, kodwa uya kuchukumisa ntoni?

Siye saqhuba uvavanyo lokuthelekisa kwiminyaka embalwa emva kunye namacandelo avela kwisiseko esikhulu semveliso efana neYongnian eHebei. Sasinezinc esemgangathweni, ichromate eluhlaza okwesibhakabhaka, kunye neegaskets ezimnyama kwi-rack yovavanyo kwindawo engaphandle ekhuselweyo. I-black coating ibonise ukufiphala kwe-blotchy kwiinyanga ezi-4. Umbala oluhlaza okwesibhakabhaka ubambe umbala ngcono kodwa uphuhlise imveliso emhlophe yomhlwa emaphethelweni ngokukhawuleza. I-zinc ecacileyo yayibonakala ibuthuntu ngokulinganayo kodwa ayizange iqhubele phambili kumhlwa obomvu ngokukhawuleza. Yayisisifundo esicacileyo: umaleko owongeziweyo wombala ngamanye amaxesha unokwenza ngokungaqondiyo iintanda ezincinci okanye iiyantlukwano kumaleko wechromate eziba ziindawo zokuqalisa ukubola.

Ukuguquguquka koMveliso: Yonke ikwiNkqubo

Ukuqina akukhona malunga ne-spec yemathiriyeli; ibotshelelwe ngokunzulu kulawulo lwenkqubo. Umthengisi owaziwayo njengo I-Sunnian Zitai Festener Fishaner Comment Com., ukuxhathisa indawo yayo kweyona ndawo inkulu yaseTshayina isiseko senxalenye, ngokuqhelekileyo inomlinganiselo kunye nenkqubo ehlayo. Kodwa nalapho, umtyholi ukwiinkcukacha. Amanyathelo abalulekileyo kukulungiswa komphezulu ngaphambi kokufakwa, ubukhulu kunye nokulingana kwediphozithi ye-zinc, ixesha kunye nokugxininiswa kwindawo yokuhlambela i-chromate, kunye nobushushu kunye nokutywinwa kwebhafu yedayi.

Inyathelo lechromate ekhawulezileyo okanye idayi etywinwe ngokungafanelekanga iya kukhokelela ekungaphumelelini kwangaphambi kwexesha. Ndifumene iibhetshi apho umbala ukhutshiwe ngoxinzelelo lomnwe. Lo ngumba wokutywinwa kwasemva kokufakwa. I-substrate nayo ibalulekile. I-gasket egxininiswe kwintsimbi ephantsi kwekhabhoni ngokuchasene nenye evela kwi-alloy ye-high-grade iya kuba ne-texture eyahlukileyo emva kokucoca, echaphazela ukunamathela kwi-plating. I-Sunnian Zitai Festener Fishaner Comment Com. kunye nabavelisi abakhulu abafanayo banenzuzo yemithombo yempahla ekrwada engaguqukiyo kunye nemigca ezenzekelayo, enciphisa oku kuguquguquka xa kuthelekiswa neevenkile zemisebenzi ezincinci.

Ingcebiso enye esebenzayo endihlala ndiyinika: cela icandelo elinqamlezayo okanye uvavanyo olulula lweteyiphu (nge-ASTM D3359) kwiisampulu. Ayisiyo imigangatho yeefasteners, kodwa ikuxelela malunga nokubambelela. Cinezela iqhekeza leteyiphu encamathelayo eyomeleleyo kwindawo enombala, uyikrazule. Ukuba umbala uza nayo, unengxaki yokudibanisa eya kubonakala kwindlela yokuhamba okanye indibano.

Umele Uyisebenzise Nini, Nexesha Lokuhamba

Ngoko, ngaba konke kubi? Hayi. Imalunga nolindelo olulawulwayo. Kumalungu angaphakathi kwindawo eyomileyo, elawulwayo-cinga iiracks zeseva, ii-assemblies zefenitshala yeofisi, okanye iipaneli zoomatshini bangaphakathi-i-zinc plating enemibala iyamangalisa kwinxalenye yokuchongwa kwaye ikhangeleka njengengcali. Ukuqina kwayo kwanele ngokugqibeleleyo. Kwakhona, kwizicelo ezifuna ukukhuselwa kwe-EMI/RFI, isiseko se-zinc sibonelela nge-conductivity, kwaye umbala ungasetyenziselwa ukubonisa iindlela ezithile zokumisa okanye umqondiso.

Ukungaphumeleli kuvela ekusebenziseni kakubi. Ndicebise ngokuchasene nokuzisebenzisa kwi-automotive underbody trim component kube kanye, kodwa iqela loyilo lalibekwe kwindawo emnyama ye-aesthetics. Bayivavanya kwigumbi kwaye yaphumelela uvavanyo lokutya komjikelo omfutshane. Umhlaba wokwenyani? Ityuwa yendlela, ukuqhekeka kwegrabile, kunye nokufuma okuthe rhoqo kukhokelele ekusileleni kwezithambiso kwisithuba esingaphantsi konyaka. Satshintshela kumatshini wokugalela intsimbi kunye nedyasi emnyama, eyayibiza imali eninzi kodwa ihlala ixesha elide. Isifundo: Tshatisa ingcaciso neyona ndawo imbi, ingqongqo, hayi eyona ifanelekileyo.

Enye i-niche kodwa inqaku elibalulekileyo: ukuhambelana kwegalvanic. I-zinc-plated steel gasket ngokuchasene nendlu ye-aluminium idala isibini se-galvanic, kodwa i-zinc isondele kwi-aluminium kwi-nobility scale, ngoko ayinamandla kakhulu, kunokuthi, i-gasket yensimbi ecacileyo. Umbala wombala wongeza umqobo omncinci, ongeyena-conductive, onokunciphisa kancinci i-galvanic current ukuba ihambelana. Kodwa xa sele ugqibile, ubuyela kuqhagamshelwano lwe-zinc-aluminium. Yinto encinci, kodwa kwiindawo ezivaliweyo ze-elektroniki, ikuluhlu lokutshekisha.

Ngaphaya kwePlate: Iindlela ezingezinye

Xa okusingqongileyo kufuna umbala kodwa nako ukuhlala ixesha elide, kuya kufuneka ujonge ngaphaya komgangatho we-electroplated color zinc. Iijiyometri ezifana neegaskets, ezinemiphetho yazo kunye neemilo ezinesitampu ezihlala zintsonkothile, zingumngeni ukunxiba ngokulinganayo. Enye indlela kukutyalwa koomatshini ngombala, onokunika ubukhulu obungcono kwimiphetho. Enye i-powder coating, kodwa loo nto yongeza ubukhulu obubalulekileyo kwaye inokuchaphazela ukunyanzeliswa kwesicelo se-gasket-ingaphezulu kwikhava okanye izibiyeli.

Ukomelela okuphezulu, impendulo kaninzi kuku-decouple umsebenzi ukusuka kumbala. Sebenzisa isiphelo esomeleleyo njengeGeomet? okanye iDacromet? ukwenzela ukhuseleko lomhlwa, uze wongeze isiziba esinombala, iwasha yealuminiyam enodizekisiweyo, okanye uphawu olupeyintiweyo lokuchonga. Kubiza kakhulu, kodwa bubunjineli obunyanisekileyo. Ngamanye amaxesha, esona sisombululo kukusebenzisa i-gasket ecacileyo, ephezulu ye-zinc-nickel kwaye wamkele umbala ongathathi hlangothi wesilivere-ngwevu. Ukunganyangeki kwayo kokutshizwa kwetyuwa kunokuba ziiyure ezingama-500+, kuncitshiswe nayiphi na ikroti enemibala.

Ekugqibeleni, ukucacisa a I-zulthi enemibala ye-xes lulungelelwano lweendleko, ubuhle, kunye nokuvezwa kwehlabathi lokwenyani. Kugqityiwe ngokufanelekileyo xa kusetyenziswe ngamehlo acacileyo. Musa ukuthembela kwikhathalogu yokumelana ne-corrosion ephezulu ibango ngexabiso lobuso. Fumana iisampulu, uzibeke phantsi kwemeko yakho yokwenyani-igumbi lokufuma, ibhokisi ye-UV, isuntswana lokusula i-solvent-kwaye ubone ukuba yintoni eyoyisakalayo kuqala. Amehlo akho kunye neglasi elula yokukhulisa iya kukuxelela ngaphezu kwalo naliphi na iphepha ledatha elenziwe lafana nelo elivela kumniki-nkonzo, nkqu nelo eliqinileyo elisekelwe kwindawo enkulu efana I-shoan fiitai. Ukungaguquguquki kwabo kukufumana isiqalo esihle, kodwa isicelo sakho sichaza umgca wokugqibela.
