Iibholiti ezinemibala ye-zinc: ukuveliswa kwezinto ezintsha? 

Ubona 'iibholiti ezinemibala ye-zinc' kwiphepha elithile okanye iwebhusayithi yomthengisi, kwaye ukusabela kwangoko kumgca wethu womsebenzi kuhlala kungumxube wokuthandabuza kunye nomdla. Ngaba yi-gimmick yokuthengisa, indlela yokuhlawula ngaphezulu kwi-fastener eqhelekileyo kunye nedash yepeyinti? Okanye ngaba kukho ubunjineli bokwenyani kunye nengxoxo yokusingqongileyo engcwatywe phantsi kwaloo maleko ebala? Ndichithe iminyaka ndikhangela kwaye ndivavanya iziqhoboshi kwiinkqubo ezahlukeneyo zangaphandle kunye nezokwakha, kwaye ndiyakuxelela, incoko ejikeleze la malungu ayifane ibe mnyama namhlophe-okanye kule meko, isilivere nebhlowu. Ibango lokuzinza lilona khonkco lokwenyani, kodwa lidityaniswe neentsomi zokusebenza, ikhemistri yokugquma, kunye nezinye iinyani eziqatha ezivela kumzi-mveliso.

Ngaphaya kweAesthetics: Umsebenzi wokwenyani woMbala

Masiyinqumle ingcamango yokuqala ephosakeleyo: umbala awuyiyo imbonakalo. Ngokuqinisekileyo, ivumela ukukhowudwa kombala kwindibano okanye ukufanisa izakhiwo, ezinexabiso. Kodwa ngengqiqo esebenzayo, loo topcoat yombala-ngokuqhelekileyo i-chromate conversion coating ngedayi okanye i-organic sealant-yeyona nto isebenzayo. Iplating ye-zinc eqhelekileyo ecacileyo okanye eluhlaza okwesibhakabhaka inika ukhuseleko lokudla kombingelelo, kodwa ubomi bayo ngokuchasene nomhlwa omhlophe, ngakumbi kwindawo efumileyo okanye engaselunxwemeni, inokuba mfutshane ngokudanisayo. Umaleko onemibala, odla ngokuba ngqindilili wekhromate enxantathu okanye engekho hexavalent, usebenza njengomqobo owomeleleyo ngakumbi. Ivala i-zinc plating ngaphantsi. Ndibone iindawo ezicacileyo ze-zinc ukusuka kwibhetshi ebonisa ukubola okumhlophe emva kweeyure ezingama-48 kuvavanyo lokutshiza ityuwa, ngelixa ezo zi-yellow iridescent ezivela kwibhetshi enye zazicocekile kwiiyure ezingama-96. Umahluko awuyonto yokuthambisa; luphuculo olusisiseko lokuxhathisa umhlwa.

Oku kukhokelela ngokuthe ngqo kwi-angle yokuzinza. Ukuba ibholithi ihlala kabini okanye kathathu ixesha elide ngaphambi kokubola, unciphisa ukuphindaphindeka kokutshintshwa, inkunkuma yezinto eziphathekayo, kunye nomsebenzi / amandla okugcina. Leyo yinzuzo ebonakalayo yomjikelo wobomi. Kodwa-kwaye inkulu kodwa-oku kuxhomekeke ngokupheleleyo kwimfezeko yale nkqubo yokugquma imibala. Ibhafu elawulwa kakubi, ixesha lokuntywiliselwa elingahambelaniyo, okanye ukuhlanjululwa ngokwaneleyo kunokukushiya unenxalenye ekhangeleka kakuhle xa ufika kodwa ingaphumeleli kwangaphambi kwexesha. Umbala unokufihla ubuninzi bezono kwinqanaba le-zinc elingaphantsi, yingakho ukuthembela kwinkqubo yomthengisi wakho kungenakuxoxisana.

Ndikhumbula iprojekthi yomzila kaloliwe osecaleni kolwandle. Umakhi wayefuna ukugqitywa kobhedu oluthile olumnyama. Siye safumana iibholiti ezinemibala ye-zinc oko kuhambelana ngokugqibeleleyo. Ngokwembonakalo, babengenasiphako. Kwisithuba nje seenyanga ezili-18, saba neengxelo zokuba nebala lomhlwa. Uhlalutyo lwasemva kokungaphumeleli lubonise ukuba i-zinc layer yayincinci kwaye i-patchy; idyasi entle yavele yagquma umsebenzi wokutyabeka okumgangatho ophantsi. Imveliso ezinzileyo, ehlala ixesha elide yaba ngumthombo wokungaphumeleli kwangaphambi kwexesha kunye nenkcitho. Isifundo yayingekuko ukuba itekhnoloji imbi, kodwa ukuba ukusebenza kwayo kuxhomekeke ngokupheleleyo kwinkqubo.

I-Chemistry Shift: Ukusuka kwi-Hex-Cr ukuya kwi-Trivalent naNgaphaya

Ukuqhuba kozinzo kuye kwatshintsha ngokusisiseko ikhemistri emva kwezi zambatho. Kangangamashumi eminyaka, umgangatho wegolide wokumelana nokonakala okuphezulu ibiyihexavalent chromate (Hex-Cr) umaleko wokudlula. Ivelise ezo zigqibo zahlukileyo ezityheli okanye eziqaqambileyo kwaye yayisebenza ngokumangalisayo. Kodwa ikwayityhefu kakhulu kwaye ine-carcinogenic, ekhokelela kwimithetho engqongqo yokusingqongileyo kunye nokhuseleko lwabasebenzi (RoHS, REACH). Ukufowunela i-Hex-Cr egqunywe ngebholiti ezinzileyo iyakuhlekisa, nokuba iphila ixesha elide.

I-innovation-inyathelo langempela elizinzileyo-kuye kwaqulunqwa i-chromate esebenzayo ye-trivalent kunye ne-non-chromium (umzekelo, i-zirconium-based, i-silica-based) yokuguqulwa kweengubo ezinokuthi zibe nombala. Ezi aziyongozi kangako. Xa umthengisi ethanda I-Sunnian Zitai Festener Fishaner Comment Com. bathetha ngokutyalwa kwe-zinc enemibala ngoku, ngokuqinisekileyo babhekisa kwezi khemistri zintsha. Ifumaneka eYongnian, intliziyo yemveliso ekhawulezayo yaseTshayina, zikwingingqi ekuye kwafuneka ukuba iqhelane ngokukhawuleza nemigangatho yokusingqongileyo yehlabathi. Utshintsho alukhethi kubathumeli ngaphandle.

Nangona kunjalo, ingxoxo yokulinganisa ukusebenza iyinyani. Iichromates zakwa-trivalent azizange zihambelane neempawu zokuziphilisa ze-Hex-Cr okanye ukumelana nokutshizwa kwetyuwa. Itekhnoloji ibambe kakhulu, kodwa ifuna ulawulo lwenkqubo oluchanekileyo. I-chemistry yokuhlambela ayixoleli kakhulu. Ndineempendulo zobugcisa ezivela kwiinkampani zeekhemikhali zokugquma zivuma ukuba ukuba i-pH okanye ubushushu buhamba, ukuhambelana kombala kunye nokusebenza kwe-corrosion yeenkqubo ezincinci kunokwahluka ngakumbi kunomgangatho omdala, onetyhefu. Ke, enye indlela ezinzileyo ifuna ubuchule obuphezulu kumenzi. Asiyonto ilula yokulahla.

IiNyinene zoBonelelo kunye neYongnian Factor

Xa uchwechwela phantsi apho ezi iibholiti ezinemibala ye-zinc zivela, umthamo omkhulu uqukuqela kumaqela afana neSithili saseYongnian eHandan. Ukugxininiswa kobuchule kunye neziseko zophuhliso apho kuyamangalisa. Inkampani efana ne-Handan Zitai Fastener, ebekwe kufutshane neendlela ezinkulu zezothutho, ibandakanya ubungakanani kunye nobuchule besi siseko. Banokuphatha lonke ikhonkco: isihloko esibandayo, ukuthunga, unyango lobushushu, ukubeka, kunye nemibala. Oku kudityaniswa ngokuthe nkqo ngundoqo kulawulo lomgangatho kwinkqubo enovakalelo njengokufakwa kombala.

Kodwa isikali sizisa imingeni yaso. Ngexesha lemfuno ephezulu, ndibone ukungaguquguquki komgangatho kuchaphazeleka kuyo yonke ibhodi kummandla. Inqanaba lokufaka imibala, elidla ngokuba linyathelo lokugqibela, linokuba ngumqobo. Ukuhlanjululwa ngokukhawuleza okanye ukucutha ixesha lokumisa ngaphambi kokupakishwa kunokukhokelela kwi-stain yokugcina emanzi-i-corrosion eyenzeka kwi-transit kuba ukufuma okushiyekileyo kubanjwe kwi-bolt. Ufumana ibhokisi yeebholiti ezinemibala emihle esele iqalisa ukugqwala emhlophe kwimingxuma. Oku akukona ukungaphumeleli kwengcamango yemveliso, kodwa ukuveliswa kwemveliso kunye namasango asemgangathweni. Kusisikhumbuzo esisebenzayo sokuba ukuzinza akukhona nje malunga nekhemikhali yokwambathisa; imalunga nenkqubo yokuvelisa yonke into ethintela inkcitho.

Iwebhusayithi yabo, I-Zitafasteners.com, ibonisa uluhlu-ukusuka kwigalvanized standard ukuya I-chinc-ipinc-ipeyintiwe iinketho. Into ongayiboniyo lutyalo-mali olungemva kwe-scenes kunyango lwamanzi amdaka kwimigca yabo yokucwenga, eyinxalenye enkulu yeendleko zendalo esingqongileyo. Ukuzibophelela komnikezeli ekuphatheni ukungcola okusuka kwinkqubo yokuqaba kunye nemibala, ngokokubona kwam, luphawu olubonisa ngakumbi isimo sabo esizinzileyo kunombala webholi ngokwayo.

Iingcaciso zeSicelo: Apho Ivakala khona (kwaye Apho Ingenziyo)

Ke, uyichaza nini ibholithi enemibala ye-zinc? Ayilophuculo lwehlabathi jikelele. Kwiindawo zangaphakathi, ezomileyo, zigqithise; i-zinc eqhelekileyo ineendleko eziphezulu. Indawo eswiti ikwimisebenzi yangaphandle apho imodareyitha ukuya kokuphezulu kokungatyanga kuyafuneka, kodwa intsimbi engatyiwayo ayibizi kakhulu, kwaye igalvanizing eshushu idiphu ininzi kakhulu okanye irhabaxa ukulungiselela ukudibanisa. Cinga ngezibiyelo zombane, ukunyuswa kwe-HVAC, ukwenza isakhelo sephaneli yelanga, izixhobo zebala lokudlala, kunye nolwakhiwo oluthile lwesinyithi.

Sizisebenzise ngempumelelo kuthotho lweepali zokukhanyisa zangaphandle zeemodyuli. Iibholithi zazifuneka ukuze zixutywe nepali yobhedu emnyama kwaye zimelane nomoya ongaselunxwemeni wedolophu. Iibholithi zekhromatiki ezinemibala entlantlu-ntathu zibonelele ngokuxhathisa umhlwa kunye nomdlalo wobuhle. Iminyaka emihlanu, ngaphandle kwesondlo, basajongeka kwaye baqhuba kakuhle. Lulo loloyiso lwengxoxo yozinzo-akukho kutshintshwa, akukho mabala, akukho callbacks.

Kodwa kukho imida. Sizame ukuzisebenzisa kwindawo erhabaxa kakhulu, intshukumo ephezulu koomatshini bezolimo. Ingubo enemibala, ngelixa i-resission-resission, yayincinci kwaye ikhawuleza igugile kwindawo ethwele, iveza i-zinc engaphantsi ekunxibeni okukhawulezileyo. Ukusilela. Isifundise ukuba ukuxhathisa i-abrasion yipropathi eyahlukileyo ngokupheleleyo. Inguqulelo entsha ithe ngqo; isombulula ingxaki yomhlwa/yochongo, hayi ukunxitywa koomatshini.

Isigwebo: Ewe ofanelekileyo, enamehlo avuleke ngokubanzi

Ngaba yinto entsha ezinzileyo? Ewe, kodwa ngeziqinisekiso ezinzima. Ukufuduka ukusuka kwi-Hex-Cr enetyhefu ukuya kwi-trivalent ekhuselekileyo okanye engeyiyo i-chrome chemistry kukuphumelela okucacileyo kokusingqongileyo kunye nempilo. Amandla okwandisa ubomi benkonzo ngokhuseleko oluphezulu lomqobo kunciphisa inkunkuma. Leyo ngundoqo wetyala elizinzileyo.

Nangona kunjalo, igama elithi uzinzo liyahlanjululwa ukuba inkqubo yokuvelisa iyinkcitho okanye ilawulwa kakubi, okukhokelela kumazinga aphezulu okwaliwa okanye ukusilela kwangaphambi kwexesha entsimini. I-innovation ayikho kwibholithi eluhlaza okwesibhakabhaka okanye etyheli; ikwi-Advanced, i-chemistry elawulwayo isetyenziswe ngokuchanekileyo phezu kwe-zinc substrate yesandi. Ifuna umenzi onobuchule, otyaliwe.

Ingcebiso yam? Musa nje uku-odola nge-swatch yombala. Ukugocagoca inkqubo. Cela iingxelo zovavanyo lwesitshizi setyuwa (ASTM B117) echaza iiyure ukuya kumhlophe kunye nomhlwa obomvu ngokugqitywa kwazo kombala othile. Buza malunga nolawulo lwabo lwamanzi amdaka. Phicotha ukuba unako. Ukuzinza kwangempela, kunye nokusebenza, kuvela kwiinkcukacha ezingemva kwe-facade enemibala. Kubathengisi abasebenza kwisikali kunye nolawulo oludibeneyo, njengabo bakwisiseko seYongnian abaye baziqhelanisa, imele inyathelo lokwenyani eliya phambili. Kwabanye, yintsimbi enemibala nje. Ukwazi umahluko yinto yonke.
