Umkhiqizi Wamathangi Amanzi Angcolile Ensimbi Engagqwali waseChina
I-Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd) yakha amathangi okugcina amanzi angcolile ensimbi engagqwali ku-304 kanye ne-316L okusetshenziselwa izimboni kanye nomasipala, kanye namathangi ensimbi ehlanganiswe nengilazi lapho ikhemistri ivumela khona udonga olungelona insimbi. I-316L ikhethwa ngenxa ye-chloride, i-sulfide kanye ne-pH ephansi; i-304 yamanzi angcolile avamile. Ithangi liyithuluzi lomoya osemkhathini noma ingcindezi ephansi ye-gauge, futhi isikhathi sokusebenza kwalo sinqunywa umugqa wamanzi, ukuma kokuphuma kanye nokuhlangana kwesembozo — konke lokhu kuyizinqumo zokucaciswa ezenziwa ngaphambi kokuba uhlelo lwamapuleti lugcinwe.
Ukugcinwa kwamanzi angcolile kusesimweni esinzima sokuhlangana kokugqwala nenqubo. Umfudlana unolaka ngezindlela ezingabonakali egameni lawo — i-chloride evela enqubweni, i-sulfide evela ezintweni eziphilayo, i-pH eshintshashintshayo phakathi nekheshi — futhi ithangi okukulo lingokwesikhashana ngokwakhiwa kwalo, lilindele isigaba sokwelashwa okungenzeka sisenze singadingeki. Ukukhetha i-304 noma i-316L yingxenye ebonakalayo yencazelo; umugqa wamanzi, indawo yokuphuma kanye nekhava yingxenya enquma ukuthi isitsha sizohlala isikhathi esingakanani. Umkhiqizi ofuna ukuhlaziywa okugcwele ngaphambi kokusho nge-alloy uphendula umbuzo owodwa obalulekile.
I-chemistry ekhetha i-alloy
I-chloride ne-sulfide yizo ezenza umonakalo; i-pH yobuningi ichaza umngcele. I-304 stainless ibamba amanzi angcolile asezingeni likamasipala kanye nemifudlana eminingi yezimboni ezilula. I-316L iqukethe i-molybdenum futhi iyisicaciso esifanele lapho i-chloride ivela khona — i-brine yenqubo, amanzi anomunyu, indawo yasogwini, noma usawoti wokulinganisa — nanglapho i-sulfide ivela kuma-sulfate noma ekuboleni kwamaprotheni, okuhlasela i-304 ikakhulukazi endaweni yomhwamuko omanzi ngaphezu koketshezi. I-pH ephansi yandisa ingxoxo kunokuba iyixazulule: lapho i-pH iyiasidi futhi kusadingeka udonga lwensimbi, ukukhethwa kwe-alloy kanye nokujiya kodonga kokubili kuyahlolwa. Lapho amakhemikhali anolaka engadingi udonga lwensimbi, ithangi le-glass-fused-to-steel eline-enamel elincibilikisiwe alinayo imiphumela ku-pH 1 kuya ku-14 futhi ngokuvamile liyimpendulo enomnotho yamavolumu amakhulu.
Izindlela zokwehluleka nokuthi ziqala kuphi
Zonke iziqukathi zamanzi angcolile zilandisa indaba efanayo uma wazi lapho okufanele ubheke khona. Indawo lapho umoya nomhlabathi kuhlangana khona yilapho ukuhwamuka kuqoqa khona usawoti futhi ukushintshashintsha kokumanzi nokoma kwenza udonga lube luncane, ngakho ibhande elingaphezu nje kwezinga elijwayelekile ngokuvamile liyindawo ephathwa kabi kakhulu esitsheni nakuba ithola ukunakwa okuncane kakhulu. Isihluzo sokuphuma kanye nokushintsha kwamaphayiphu yilapho ukuqala khona ukugqwala kwemigodi kanye nokugqwala kwezikhala, ikakhulukazi lapho umsipha wokushisela wawungagundiwe waba bushelelezi futhi ukwakheka kwezikhala kubamba uketshezi eduze kwensimbi. Ngaphansi koketshezi, izinto eziqinile ezihlala phansi zigcina ifilimu emanzi phansi nasodongeni olungezansi, okuyiseli lokugqwala kanye nomthombo wephunga. Ngenhla, umgogodla wesembozo yilapho i-gasket iguga khona nalapho umoya onganele uba yindaba. Ohlelweni lwe-enamel ukwehluleka kuhambisana nomqondo ofanayo: ukuhlukaniswa endaweni yokuhlangana kokuncibilika uma isisekelo siphoca igobolondo ukuba lingabi yindilinga, kanye nokwakheka kwezimbotshana ezincane ezivela ekushayweni kokusebenza, yingakho ipuleti ngalinye elihlanganisiwe lihlolwa nge-spark ku-1500 V DC ngaphambi kokuba lithunyelwe.
