Ukuqina kwepleyiti efakwe kwisitya esishushu-diphu? 

Makhe sinqumle i-fluff yokuthengisa. Xa umntu ebuza malunga nokuqina kweepleyiti ezifakwe ngegalvanized dip, badla ngokufumana impendulo yegeneric engama-50+ eminyaka. Ubunyani bumessier. Akunjalo nje malunga nobukhulu be-zinc yokwambathisa; malunga nokuba kwenzekani ukususela kumzuzu apho iplate ishiya i-kettle de ingcwatywe kwikhonkrithi kwaye ilibale amashumi eminyaka. Ndibone iipleyiti zisilela kwiminyaka eli-10 kwaye ezinye zijongeka zicocekile emva kwe-30, kwaye umahluko uhlala uhla kwiinkcukacha akukho mntu uthetha ngazo kumaphepha athile.

Iketile ayingoMda wokugqibezela

Uninzi lweengxoxo luqala kwaye luphele kwinkqubo yokuvuselela. I-ASTM A123, ubukhulu bokugquma, yonke loo nto. Ngokuqinisekileyo, eso sisiseko. Kodwa ndiye ndabukela iipleyiti zisonakala eyadini phambi kokuba zithunyelwe. Ukuzipakisha zintsha kwiketile ngaphandle kokugalelwa kwenkunkuma efanelekileyo? Ugawula i-coating kwiindawo zoqhagamshelwano. Ndikhumbula ibhetshi yeprojekthi yebhulorho apho kwafuneka silahle i-pallet ngenxa yokuba iikona zazingaphathwa kakubi. I-galvanizer idibene ne-spec, kodwa i ukuqina yafakwa esichengeni phambi kokufakwa. Ingcinga yokuba isikrweqe sokugqibela, esingenakuguqulwa yimpazamo yokuqala.

Emva koko kukho indawo yokugcina. Ukuba ugcina ezi ngaphandle kwiinyanga, uqala iwashi kwindawo yokugcina emanzi (umhlwa omhlophe). Ubukhulu becala i-cosmetic, kodwa ithetha ngokunqongophala kwenkathalo kwikhonkco lokugcinwa. Umqambi olungileyo okanye umthengisi, njengoHandan Zitai Fastener, uyayiqonda le nto. Indawo abakuyo eYongnian, laa ndawo inkulu yokudibanisa, ithetha ukuba bahambisa imveliso ngokukhawuleza. Ukusondela koololiwe abakhulu kunye nothungelwano lwendlela efana neBeijing-Guangzhou line ayiyona nje indawo yokuthengisa; kuthetha ukuba iipleyiti zichitha ixesha elincinci zihleli kwiimeko eziguquguqukayo, ezichaphazela ngokuthe ngqo ukuthembeka kwengubo oyihlawuleleyo.

Ukuwelda kwee-studs okanye i-anchors emva kwegalvanizing sesinye isigaba esibalulekileyo. Kuya kufuneka uphinde uvuselele indawo echatshazelwe bubushushu. Ndiye kwiindawo apho basebenzisa ipeyinti ecebileyo ye-zinc njenge-touch-up. Kwindawo epholileyo, mhlawumbi iyayibamba. Kwindawo yonxweme okanye i-icing yetyuwa, eso siqwenga sihluleka ngokukhawuleza, sidala i-pinpoint ye-corrosion ukuhlasela isiseko sentsimbi. I Iplate efakwe yinkqubo, hayi nje isiqwenga esisicaba sesinyithi.

Ukugalela ngekhonkrithi: Apho ithiyori idibana nesiphithiphithi

Apha kulapho ipleyiti yakho echazwe ngononophelo ivavanywa khona. I-chemistry yekhonkrithi ibaluleke ngaphezu kokuba abantu becinga. Imixube yekloridi ephezulu ingumbulali. Ndisebenze kwiprojekthi yegaraji yokupaka apho umxube wamandla okuqala wawu… ndlongo. Sabona ukugqabhuka kwezinki kwisithuba esingangonyaka. Ukufakwa kwegalari kwakuza kuchazwa, kodwa imeko-bume ekhonkrithi yayinobutshaba.

Isenzo somzimba sokugalela sikhohlakele. IiVibrator zinokuyilimaza ipleyiti ukuba zityhalwe ngqo kuyo. Ndikhumbula isiseko sekholomu apho i-vibrator ikhuphe i-zinc kumda wokuzinzisa. Ijongeka incinci, kodwa idale indlela. I I-HOT-DIP-IXESHA LOKUGQIBELA I-coating iyazincama, ngoko ke ulwaphulo luhlala kwindawo yokukhusela. Kulungile kude kube ulwaphulo lukwindawo yoxinzelelo olunzima, njengokujikeleza i-anchor stud.

Ubunzulu bekhava yenye yeklasikhi. Ipleyiti ibekwe ngokugqibeleleyo ephepheni. Kwisiza, iikheji ze-rebar ziyatshintsha, ukuhamba kwekhonkrithi, kwaye ngequbuliso isigqubuthelo sakho esiyi-50mm sibe yi-30mm. Ngaloo mngcele, i-carbonation ifikelela kwi-plate ngokukhawuleza. Kwindawo yekhonkrithi ye-carbonated, i-zinc idlula, kodwa ukuba isigqubuthelo asihambelani, ufumana iimeko ezahlukeneyo. Kunqabile ukusilela okufanayo; iqala kwindawo ebuthathaka.

Ukukhanya Okude: Kujongeka Njani Ukuqina Kwenyani

Ukuqina ayisiyonto yokupasa/yokusilela. Kukusetyenziswa ngokuthe ngcembe kwe-zinc layer. Kwikhonkrithi elungileyo, exineneyo, ephantsi kwekloridi, i-zinc yenza i-zincates ezinzile kwaye izolile. Inokuhlala ubomi besakhiwo. Ingxaki asifane sibe neemeko ezigqibeleleyo. Ndiphonononga iingxelo zohlolo ezivela kwizakhiwo ezindala. Iipleyiti azivuthwanga; babonisa imingxuma yendawo okanye ibala kumgca ongaphezulu wekhonkrithi, rhoqo apho ukufuma kutsalwa rhoqo.

Imeko enye: indlela yokuhamba yokucoca amanzi amdaka. Amacwecwe ayekhangeleka emakhulu ngaphandle kwaxa ukujiya kwemibhobho engaphezulu kwakuhlala kuthontsizela kwicandelo elinye lesiphelo somqadi wekhonkrithi. Loo mjikelo usoloko umanzi/wokoma wadala iseli yokubola. I-zinc yaphelelwa apho emva kweminyaka emalunga ne-15, kunye ne-corrosion encinci yentsimbi. Ipleyiti eseleyo yayilungile. Ngoko ke, i ukuqina Iminyaka eyi-15 okanye engama-50? Kuxhomekeke kwi-micro-environment.

Kungenxa yoko le nto ndithandabuza iimvavanyo zaselebhu ezikhawulezileyo. Balinganisa uhlaselo olufanayo. Ubomi bokwenyani bumalunga neziphene zasekhaya, ukunyamezela ulwakhiwo, kunye neendawo zokusingqongileyo. Umthengisi okuthengisa nje ipleyiti esemgangathweni akakuniki umfanekiso opheleleyo. Ufuna umntu ocinga ngesicelo. Ukujonga indawo efana I-Zitafasteners.com, ubona ukuba bagxile kwikhonkco lokuvelisa kunye nempahla. Kumenzi wemveliso, ukuthembeka okunyukayo kukhulu-isusa enye into ebalulekileyo. Ukwazi ukuba iipleyiti zakho zifikile zivela kwisiseko semveliso efana neYongnian ngaphandle kokubanjwa ngaphaya kwamanqaku amaninzi ogqithiselo yinto ebambekayo yokuqina.

Xa iZinc engakumbi ingeyiyo impendulo

I-reflex eqhelekileyo kukucacisa isambatho esinzima. Izigidi ezininzi, iminyaka emininzi. Kodwa kwipleyiti edibeneyo enezikhonkwane ezidityanisiweyo, isambatho esityebileyo esigqithileyo sinokuba brittle kwaye sithambekele ekuqhekekeni ngexesha lokuphatha okanye ukubeka ikhonkrithi. Ndayibona ibuhlungu. Kukho indawo epholileyo. Kwakhona, isambatho esityebileyo sinokuchaphazela ukulingana kunye nokudityaniswa kokunyamezela. Ngamanye amaxesha, ukugquma okusemgangathweni okuhambelanayo, ukusetyenziswa kakuhle komgangatho ogqithiseleyo, ongaqhelekanga.

Enye indlela ayisoloko ingenabala. Kwizicelo ezininzi, oko kugqithise. I-robust hot-dip galvanized plate, kunye nengqalelo kwiinkcukacha ze-post-galvanizing, ixabisa kakhulu. Undoqo kukuphatha njengenkqubo, hayi imveliso. Kukwenziwa, ukugalela, ukuphatha, ukugcina, ukufakela, kunye nokubekwa kwekhonkrithi. Ukuqhawuka kwelo khonkco likhefu kwi ukuqina.

Siye sazama ii-duplex coatings (galvanizing + powder coat) kwindawo eveziweyo yoyilo lwezakhiwo kanye. Iphupha elibi. Ibhondi yekhonkrithi yayikhohlisayo, kwaye nayiphi na i-chip ngexesha lokugalela yayingumgibe wokufuma. Ubuyele kwidiphu eshushu esemgangathweni. Ngamanye amaxesha isisombululo esisemgangathweni, esenziwa ngokuqwalasela ngokugqithiseleyo iinkcukacha, sesona sihlala sihlala.

I-Takeaway: Yinkqubo, hayi iMveliso

Ngoko, buyela kumbuzo wokuqala. Ukuqina kwepleyiti efakwe kwi-galvanized ye-hot-dip kuncinci malunga nepleyiti ngokwayo kwaye ngakumbi malunga nenkqubo eyinxalenye yayo. Unokufumana ipleyiti egqibeleleyo kwisiseko esikhulu sokwenziwa kwemveliso efana nale iHandan Zitai asebenza kuyo, kodwa ukuba iqela lakho lesayithi liyiphatha njengentsimbi yentsimbi, ulahlekile.

Isigwebo sobuchwephesha siza ekuchazeni kungekuphela nje ukugquma, kodwa iimfuno zokuphatha, imiyalelo yokugcina, kunye namanqaku ofakelo. Kukukhetha ababoneleli abayinxalenye ye-ecosystem edibeneyo yoshishino-apho iipleyiti zihamba ukusuka kwiketile ukuya kwilori ukuya kwindawo enengxabano encinci-kuba oko kunciphisa iindawo zomngcipheko.

Ekugqibeleni, ukuqina kufunyenwe, akuchazwanga. Lisixa sekhulu elincinci, izigqibo ezichanekileyo ukusuka kuyilo ukuya kuthululelwa. I-hot-dip galvanizing lolona khuselo lwakho lokuqala, kodwa ayisiyondawo yokunyanzela. Ingumaleko wedini obomi bayo buxhomekeke kwindlela oyikhusela ngayo, ixesha elide emva kokuba ishiye i-rack ye-galvanizer.
