Ngokunyaniseka, xa ndiqala ukuva igama liphoswa ngapha nangapha kumboniso wezorhwebo kwiminyaka embalwa edlulileyo, ukusabela kwam kwangoko yayikukuthandabuza. Enye i-buzzword yokuthengisa, ndacinga. Ihlabathi le-gasket lizele ngamabango malunga nokuphila ixesha elide kunye ne-eco-friendlyliness ehlala ingabambeli phantsi koxinzelelo lokwenyani, ukuvezwa kweekhemikhali, okanye imozulu yakudala ecacileyo. Wonke umntu uthetha ngayo iigaskets eziphekiweyo ngenxa yokumelana nomhlwa, kodwa uqhwabe umbala ngaphezulu? Oko kwakuhlala kuvakala ngathi liqhinga lokuthambisa, indlela yokubiza ngaphezulu kwenxalenye enokusilela ngenxa yokuba iitshiphusi zeplating okanye ziphazamisana netywina. Ingqikelelo yoshishino eqhelekileyo - enye endabelana ngayo - yayikukuba mhlawumbi ufumana itywina elisebenzayo okanye elihle. Ingcamango yokuba umbala wombala ngokwawo unokuba negalelo ekusebenzeni nasekuzinzeni kwakubonakala ngathi kukwelula.

Umbono ongeyiyo ongundoqo: Umbala njengeSigqibo nje

Apha kulapho amava asebenzayo ekhaba khona. Impazamo kukujonga i-plating yombala njenge-passive, umaleko wokuhombisa. Kwi-plating ye-zinc esemgangathweni, ufumana ukhuseleko lokutya kwedini, ngokuqinisekileyo. Kodwa umbala, ofumaneka ngokuguquguquka kwechromate (blues, yellows, blacks, etc.), ayingowokuchonga amalungu okanye oomatshini bokuthelekisa. Olo maleko obhityileyo wechromate okunene wongeza ukuxhathisa kokubola kwe-zinc engaphantsi. Yinto yokutywina yomaleko wegalvanized. Ngoko, a igasket efakwe ngombala ayikho igalvanized + ipeyinti. Yinkqubo yonyango engaphezulu epheleleyo. I-engile yozinzo iqala apha: ukuba le combo yandisa ubomi benkonzo ngokubonakalayo kwindawo ezinobundlongondlongo obuphakathi (cinga amaqonga aselunxwemeni anesitshizi setyuwa okanye umoya wezityalo zekhemikhali), unciphisa ukuphindaphindeka kokutshintsha, ixesha lokuphumla, kunye nenkunkuma yezinto eziphathekayo kubomi be-asethi.

Kodwa nantsi into yokubanjiswa kwehlabathi lokwenyani, leyo ufunda kuphela ngokucacisa ezi projekthi okanye ukujongana nokusilela. Ayizizo zonke iiplating zemibala ezilinganayo. Ubunzima kunye nomgangatho we-zinc layer zisisiseko. Ndikhe ndazibona iigaskets apho umbala wawudlamkile kodwa i-zinc substrate yayibhityile kakhulu, ikhokelela kumhlwa obomvu wopha emva kwexesha elithile. Indawo yokungaphumeleli yayingeyiyo i-gasket material ngokwayo, kodwa isithintelo sokuthotywa kwe-corrosion. Isithembiso esizinzileyo siyahlukana ukuba imveliso ayinikezi ibango layo lokuqina. Ikunyanzela ukuba ujonge ngaphaya kwe-spec sheet kwaye ubuze malunga nolawulo lwenkqubo. Umthengisi onje I-Sunnian Zitai Festener Fishaner Comment Com., esekelwe kwi-hub enkulu ye-fastener yase-China e-Yongnian, e-Hebei, ihlala inenzuzo yemveliso edibeneyo. Ukulawula izigaba zokugalela kunye nokucwenga ngaphakathi endlwini, endaweni yokukhupha abasebenzi ngaphandle, kunokuthetha ukungaguquguquki okungcono - eyona nto ibalulekileyo kodwa ihlala ingahoywa kwintsebenzo yenyani yomjikelo wobomi.

Emva koko kukho i-chemistry yechromate ngokwayo. Ishishini liyahamba, nangona licotha, lisuka kwi-hexavalent chromium (eyakudala, esebenza kakhulu kodwa enetyhefu kwaye elawulwayo ekugqityweni kwe-iridescent yegolide) ukuya kwi-trivalent chromates. Ezi nkqubo zemibala emitsha azinabungozi kangako. Xa umenzi etyala imali kwimigca yechromate ene-trivalent, linyathelo elibambekayo elisingise kwinkqubo yokwenziwa ezinzileyo, ukunciphisa umngcipheko wokusingqongileyo kunye nempilo yabasebenzi. Ngoko ke, ukutsha akusoloko kwimveliso oyibambe ngesandla, kodwa kwiinkqubo ezibuyela kumgangatho wefektri. Xa uvavanya, kuyafaneleka ukubuza ukuba luhlobo luni lwechromate olusetyenziswayo. Impendulo ikuxelela okuninzi malunga nokuba izinto eziphambili zenkampani zilala phi.

Imeko kwindawo: IBhanki yeValve Retrofit

Makhe ndikunike umzekelo obambekayo osuka kumzi-mveliso wokucoca amanzi esiye sabonisana nawo okwethutyana emva. Babenemiba ephindaphindiweyo kunye ne-zinc-plated gaskets kwi-valve manifolds yangaphandle. Ukonakala kwakubangela ukuxhuzula kunye nokuvuza, okukhokelela ekulahlekelweni kwamanzi kunye nokugcinwa kwentloko rhoqo kwiinyanga ezili-18. Sicebise ulingo kunye nebhetshi ye iigaskets ezenziwe ngombala ezifakwe kwi-galvanized usebenzisa iblue trivalent chromate finish. Umbala ubucelwe liqela lolondolozo ukuze uchongwe lula kumalungu amadala esilivere ezinc.

Kwiminyaka emithathu ukuya phambili, ezo ntlobo zininzi zisasebenza ngaphandle kokusilela okunxulumene ne-gasket. Iindleko mhlawumbi ibiyi-15-20% ephezulu kwiyunithi nganye ekuqaleni. Kodwa xa ujonga iindleko zabasebenzi beqela labantu ababini abachitha usuku ukuze bathathe indawo yebhanki ye-gaskets, kunye neendleko zokunciphisa ixesha lokuvelisa okanye ilahleko yamanzi, uqoqosho lutshintsha kakhulu. Ukuphumelela kozinzo kube kuphindwe kabini: ukuncitshiswa okukhulu kokusetyenziswa kwenxalenye kunye nemveliso ehambelanayo/indawo yezothutho, kunye nothintelo lokuvuza okunokuba kho kongcoliseko kwiitywina ezingaphumelelanga. Olu luhlobo lozinzo olubonakalayo olubalulekileyo - ukusebenza kakuhle kunye nokunciphisa inkunkuma okuqhutywa licandelo elihlala ixesha elide.

Isifundo yayingekuko ukuba umbala-ufakwe isoloko iyimpendulo. Ngobushushu obuphezulu okanye obugqithisileyo bemichiza, uya kujonga kwi-stainless okanye kwi-PTFE. Kodwa kwi-swath enkulu yezicelo zemizi-mveliso kuluhlu oluphakathi lokutya, le ndibaniselwano ibetha ngaphezulu kobunzima bayo. Itshintshe imbono yam ukusuka ekuyiboneni njengegimmick ukuya ekuyithatheni ingqalelo njengesixhobo esisemthethweni sokwandisa amaxesha olondolozo.

INyaniso yoVeliso kunye noBonelelo

Ukuntywila nzulu, umbuzo wokuzinza awukho nje malunga nemveliso esetyenziswayo. Imalunga nendlela eyenziwe kwaye ishukunyiswe ngayo. Apha kulapho ijografi kunye nelojistikhi zingena khona. Inkampani emi kwisiseko esigxininisiweyo sokwenza izinto, njengeHandan Zitai eseYongnian ngokufikelela ngokuthe ngqo kumzila kaloliwe omkhulu kunye neendlela (iBeijing-Guangzhou Railway kunye neNational Highway 107 zilapho), inenzuzo efihlakeleyo. Ulungiselelo olusebenzayo luthetha ukukhutshwa kwekhabhoni ephantsi ngokuthunyelwa xa imathiriyeli ekrwada ingena kwaye iimpahla ezigqityiweyo ziphuma. Kumthengi wehlabathi, ukudibanisa iodolo ye iigaskets eziphekiweyo kunye nezinye iziqhoboshi ezisuka kumthombo omnye, oqhagamshelwe kakuhle zinokucutha iindleko zizonke zokusingqongileyo zokuthengwa kwempahla. Yinkqubo yenkqubo engafane ikhankanywe kwiincwadana zemveliso kodwa ibalulekile kubalo lulonke lonyawo.

Kumgangatho wefektri, impembelelo yokusingqongileyo ixhomekeke kunyango lwenkunkuma. I-zinc plating kunye ne-chromating ivelisa amanzi amdaka. Abavelisi abakhokelayo kwimimandla efana neYongnian ngoku baphantsi kwemithetho engqongqo yokusingqongileyo, banyanzelisa utyalo-mali kwi-loop evaliweyo okanye kwiinkqubo zonyango eziphambili. Xa uvela kumenzi othembekileyo, uxhasa ngokungathanga ngqo imveliso elawulwayo, ecocekileyo. Luhlobo lokuzinza kwekhonkco lokubonelela. Enye indlela - ukuthenga eyona ndlela inexabiso eliphantsi kwivenkile engalawulwayo - kunokonga iisenti ngesiqwenga ngasinye kodwa ikhuphele ngaphandle iindleko zokusingqongileyo ngendlela eqatha. Olu lubizo lobuchwephesha ekufuneka silwenzile rhoqo: elona xabiso liphantsi xa lithelekiswa nelona xabiso liphantsi lokwenyani.

Apho i-Innovation isehla imfutshane

Masingaze sithabatheke, nangona kunjalo. Ukuyibiza njengento entsha ezinzileyo kufuna isiqinisekiso esinzima. Inkqubo isasebenzisa amandla amaninzi (iibhafu zokufudumeza izitya) kwaye isebenzisa imichiza. Ukuqaliswa kwenyani kuya kuba yinto engeyiyo ityhefu, i-low-energy coating ehambelana okanye edlula ukusebenza kwe-zinc + trivalent chromate. Asikabikho. Ezinye iicolymers ezisekwe kwibhayoloji okanye eziphucukileyo zibonisa isithembiso kwiilebhu kodwa ziswele amashumi eminyaka okuthembeka okungqiniweyo okufunwa ngumzi-mveliso kumatywina abalulekileyo.

Enye i-hiccup ebonakalayo yi-galvanic corrosion. Ukubhanqa a igasket efakwe ngombala ngentsimbi engasebenziyo (njengensimbi engenasici) kwindawo emanzi inokukhawulezisa ukubola kwe-zinc. Kufuneka uqaphele ukubhanqa kwezinto. Ndiyibonile igasket ecwecwe kakuhle isilele ngokukhawuleza kuba ifakwe phakathi kweeflange ezimbini ezingenasici kumngxunya ohlala ufumile. I-gasket izinikele ngokufanelekileyo, kodwa ayisosiphumo esizinzileyo eso. I-takeway? Akukho zixhobo zisisombululo jikelele. Ukuyichaza ngokuchanekileyo sisiqingatha sedabi.

Isiphelo: Inyathelo lePragmatic, hayi iPanacea

Ngoko, buyela kumbuzo wokuqala. Ngaba iigasthi ezifakwe ngentsimbi ezinemibala ziyinto entsha ezinzileyo? Ukusuka kwimbono ecacileyo, iibhutsi-emhlabeni, ndingathi zimele indaleko yepragmatic ukuya kulondolozo oluzinzileyo. Ayibobuchwephesha obuhlaza benguquko. Igalelo labo lokuzinza lifunyanwa ngokwandiswa kobomi obubonakalayo, utshintsho lweshishini ukuya kwiichromates ezikhuselekileyo ezinqabileyo, kunye nokusebenza ngokukuko abakwenzayo xa kusetyenziswe ngokuchanekileyo.

Into ephambili kukubabona njengenkqubo: isiseko se-zinc esisemgangathweni, i-chromate layer yanamhlanje, kunye nolawulo lokuvelisa olomeleleyo. Ababoneleli abakuqondayo oku, njengabo banezixhobo ezidityanisiweyo kwiindawo zemveliso, ngabo abaphumeza isithembiso. Sisixhobo. Kwaye njengaso nasiphi na isixhobo, ixabiso layo - kunye ne-quotient yozinzo - igqitywe ngolwazi kunye nenjongo yomntu oyisebenzisayo. Ungayihoyi i-hype, gxila kwiinkcukacha zesicelo, kwaye ngokwenene zinokuba yinxalenye encinci kodwa enentsingiselo yokwakha iziseko zemizi-mveliso ezihlala ixesha elide, ezingenankcitho. Le yeyona nto intsha: ukutshintsha indlela esicinga ngayo ngendima yecandelo elithobekileyo kumfanekiso omkhulu.
