Umehluko phakathi kwepayipi lensimbi eligayiwe elifakwe i-galvanized kanye nepayipi lensimbi elifakwe i-hot-dip, ungalihlola kanjani ikhwalithi yalo?

Umehluko phakathiipayipi elifakwe i-galvanized kusengaphambilifuthiIpayipi Lensimbi Elakhiwe Nge-Hot-DIP

1. Umehluko ngenqubo: Ipayipi elihlanganisiwe elishisayo lifakwa i-galvanized ngokucwilisa ipayipi lensimbi ku-zinc encibilikisiwe, kuyilaphoipayipi elifakwe i-galvanized kusengaphambiliimbozwe ngokulinganayo nge-zinc ebusweni bomcu wensimbi ngenqubo yokufakelwa nge-electroplating.

2. Umehluko wesakhiwo: Ipayipi eligoqekile elishisayo liwumkhiqizo onama-tubular, kuyilapho ipayipi lensimbi eligoqekile liwumkhiqizo womcu onobubanzi obukhulu nobukhulu obuncane.

3. Izicelo ezahlukene: Amapayipi ashisayo agqunywe nge-galvanized asetshenziswa kakhulu ekuthuthweni koketshezi namagesi, njengamapayipi okuhambisa amanzi, amapayipi kawoyela, njll., kuyilapho amapayipi ensimbi agqunywe nge-galvanized esetshenziswa kakhulu ekukhiqizeni imikhiqizo ehlukahlukene yensimbi, njengezingxenye zezimoto, amagobolondo ezinto zasekhaya nokunye.

4. Ukusebenza okuhlukile kokulwa nokugqwala: ipayipi eligoqiwe elishisayo linokusebenza okungcono kokulwa nokugqwala ngenxa yesendlalelo esijiyile esigoqiwe, kuyilapho i-strip yensimbi egoqiwe inokusebenza okuphansi kokulwa nokugqwala ngenxa yesendlalelo esigoqiwe esinciphile.

5. Izindleko ezahlukene: inqubo yokukhiqiza ipayipi elifakwe igesi elishisayo iyinkimbinkimbi futhi iyabiza, kuyilapho inqubo yokukhiqiza ipayipi lensimbi elifakwe igesi ilula futhi ishibhile.

Ukuhlolwa kwekhwalithi yepayipi lensimbi eligayiwe elifakwe i-galvanized kanye nelishisayo
1. Ukuhlolwa kokubukeka
Ukuphela kobuso: Ukuhlolwa kokubukeka kugxile kakhulu ekutheni ubuso bepayipi lensimbi buyisicaba futhi bubushelelezi, ngaphandle kwe-zinc slag esobala, isimila se-zinc, ukulenga kokugeleza noma ezinye iziphambeko zobuso. Ubuso obuhle bepayipi lensimbi elihlanganisiwe kufanele bube bushelelezi, kungabi namabhamuza, kungabi nazimfa, kungabi nazimila ze-zinc noma ukulenga kokugeleza kwe-zinc kanye nezinye iziphambeko.

Umbala kanye nokufana: Hlola ukuthi umbala wepayipi lensimbi uyalingana futhi uyahambisana yini, nokuthi ngabe kukhona yini ukusatshalaliswa okungalingani kwengqimba ye-zinc, ikakhulukazi ezindaweni ezihlanganisiwe noma ezihlanganisiwe. Ipayipi lensimbi elifakwe ngogesi elishisayo ngokuvamile libonakala limhlophe njengesiliva noma limhlophe qhwa, kanti ipayipi lensimbi elifakwe ngogesi ngaphambili lingase libe nombala okhanyayo kancane.

2. Ukulinganisa ubukhulu be-zinc
Isilinganiso Sokujiya: Ubukhulu besendlalelo se-zinc bulinganiswa kusetshenziswa i-coated thickness gauge (isb. i-magnetic noma i-eddy current). Lesi yisibonakaliso esibalulekile sokunquma ukuthi i-zinc coating iyahlangabezana yini nezidingo ezijwayelekile. Ipayipi lensimbi eligayiwe elishisayo livame ukuba nesendlalelo se-zinc esijiyile, ngokuvamile esiphakathi kwama-micron angu-60-120, kanti ipayipi lensimbi eligayiwe ngaphambilini linosendlalelo se-zinc esijiyile, ngokuvamile esiphakathi kwama-micron angu-15-30.

Indlela yesisindo (ukuthatha amasampula): Amasampula akalwa ngokwezinga elijwayelekile futhi isisindo sengqimba ye-zinc endaweni ngayinye sibalwa ukuze kutholakale ukujiya kwengqimba ye-zinc. Lokhu kuvame ukunqunywa ngokulinganisa isisindo sepayipi ngemva kokuyithatha.

Izidingo ezijwayelekile: Isibonelo, i-GB/T 13912, i-ASTM A123 kanye nezinye izindinganiso zinezidingo ezicacile zokujiya kwesendlalelo se-zinc, kanti izidingo zokujiya kwesendlalelo se-zinc zamapayipi ensimbi ezinhlelo zokusebenza ezahlukene zingahluka.

3. Ukufana kwesendlalelo esenziwe nge-galvanized
Isendlalelo se-galvanized sekhwalithi ephezulu siyafana ngokuthungwa, akukho ukuvuza futhi akukho monakalo we-post plating.

Akukho mphunga obomvu otholakala ngemva kokuhlolwa ngesisombululo se-copper sulfate, okubonisa ukuthi akukho ukuvuza noma umonakalo odalwe ngemva kokufakwa kwe-plating.

Lena indinganiso yezinsimbi ze-galvanized zekhwalithi ephezulu ukuqinisekisa ukusebenza kahle nokubukeka okuhle kakhulu.

4. Ukunamathela okuqinile kwengqimba ehlanganisiwe
Ukunamathela kwesendlalelo esihlanganisiwe kuyinkomba ebalulekile yekhwalithi yepayipi lensimbi elihlanganisiwe, okubonisa izinga lokuqina kwenhlanganisela phakathi kwesendlalelo esihlanganisiwe nepayipi lensimbi.

Ipayipi lensimbi lizokwakha ungqimba oluxubile lwe-zinc ne-iron ngesisombululo se-galvanizing ngemva kokusabela kwebhavu lokucwilisa, futhi ukunamathela kongqimba lwe-zinc kungathuthukiswa ngenqubo yesayensi neqondile ye-galvanizing.

Uma ungqimba lwezinki lungaphumi kalula uma lucindezelwa ngesando senjoloba, lokhu kubonisa ukunamathela okuhle.
