Okokuqala: Isigaba sezinkuni:
Ukhuni oluqinile lwe-Anticorrosive: imvelo, imvelo futhi iphephile (ukhuni lunombala walo wangempela, oluluhlaza kancane).Eqinisweni, ngaphezu kwezici zokulwa nokugqwala, izinkuni ezilwa nokugqwala nazo zinezimpawu zokungena kahle kanye nokumelana okuqinile nokulahlekelwa.Ngesikhathi esifanayo, kungavimbela ukuguqulwa komswakama wezinkuni eziphathwayo futhi kunciphise izinga lokuqhekeka kwezinkuni.Ukhuni oluvamile lwasekhaya olulwa nokugqwala luhlanganisa ikakhulukazi izinto ezimbili: I-Russian Pinus sylvestris kanye ne-Nordic Scots Pine.Ukhuni olulondolozayo olwenziwa ngophayini waseRussia ngokuyinhloko luwukwelashwa ngokhuni olulondolozayo lwezingodo ezingeniswa eChina, futhi eziningi zazo ziphathwa ngama-CCA agents.Izinkuni ezilondolozayo ezenziwe nge-Nordic red pine ziphathwa ngendlela elondolozayo phesheya, futhi ukhuni olulondolozayo oluthunyelwa ezweni ukuze luthengiswe ngokuqondile luphathwa ngama-agent we-ACQ futhi ngokuvamile lubizwa ngokuthi "ukhuni lwaseFinland".Abantu bajwayele ukubiza ukhuni olulondolozayo njengokhuni lwaseFinland.Eqinisweni, lokhu akulungile.Kulula ukuthi abantu abangaqondi ukhuni olulondolozayo bangaqondi kahle.
Okubili: Insimbi engagqwali:
Insimbi engagqwali ne-asidi ifushaniswa njengensimbi engagqwali.Ingaphezulu lepuleti lensimbi engagqwali libushelelezi futhi linepulasitiki ephezulu, ukuqina namandla okusebenza.Imelana nokugqwala ngama-asidi, amagesi e-alkaline, izixazululo neminye imidiya.Kuyinsimbi okungelula ukugqwala, kodwa ayinalo nhlobo ukugqwala.Insimbi engagqwali ipuleti lensimbi elimelana nemithombo yezindaba ebuthaka efana nomkhathi, isitimu namanzi, kuyilapho insimbi emelana ne-asidi isho ipuleti lensimbi elimelana ne-asidi, i-alkali, usawoti kanye nezinye imidiya egqwala amakhemikhali.Yakhiwe ngensimbi engagqwali kanye nensimbi engamelana ne-asidi.Insimbi ekwazi ukumelana nokugqwala komkhathi ibizwa ngokuthi insimbi engagqwali, kanti insimbi ekwazi ukumelana nokugqwala kwamakhemikhali ibizwa ngokuthi insimbi engamelana ne-asidi.Ngokuvamile, insimbi enokuqukethwe kwe-Wcr engaphezu kuka-12% inezici zensimbi engagqwali.Ngokuya nge-microstructure ngemva kokwelashwa kokushisa, insimbi engagqwali ingahlukaniswa ngezigaba ezinhlanu: i-ferritic stainless steel, martensitic stainless steel, austenitic stainless steel, Austenitic-ferritic stainless steel kanye ne-precipitated carbide stainless steel.
Ngenxa yokuthi insimbi engagqwali inokumelana nokugqwala okuhle kakhulu, ukwakheka, ukuhambisana, kanye nokuqina ebangeni lokushisa elibanzi, isetshenziswe kabanzi embonini esindayo, embonini ekhanyayo, embonini yezidingo zansuku zonke, ukuhlobisa izakhiwo nezinye izimboni..
Ezintathu: Isigaba seshidi le-Hot-dip galvanized:
Ishidi lensimbi eliphehliwe ukuvimbela ukugqwala ebusweni beshidi lensimbi nokwandisa impilo yalo yesevisi.Ingaphezulu leshidi lensimbi limbozwe ungqimba lwezinc zensimbi.Lolu hlobo lweshidi lensimbi lubizwa nge-galvanized sheet.
Ngokwezindlela zokukhiqiza nezokucubungula, ingahlukaniswa ngezigaba ezilandelayo:
①Ishidi lensimbi elinothayela oshisayo.Ipuleti elincane lensimbi licwiliswa kubhavu we-zinc oncibilikisiwe, ukuze ipuleti elincane lensimbi elinongqimba lwe-zinc linamathele phezulu.Njengamanje, inqubo eqhubekayo yokugaya isetshenziselwa ikakhulukazi ukukhiqiza, okungukuthi, ishidi lensimbi eligoqiwe lihlala licwiliswa emanzini okugeza nge-zinc encibilikisiwe ukwenza ishidi lensimbi;
②Ishidi lensimbi elihlanganisiwe.Lolu hlobo lwepuleti lensimbi nalo lwenziwa ngendlela yokucwilisa okushisayo, kodwa ngemva kokuba seliphumile ethangini, lishiselwa ku-500 ℃ ngokushesha ukuze lenze ifilimu yengxubevange ye-zinc nensimbi.Lolu hlobo lweshidi elinezinsimbi lunokunamathela okuhle kopende kanye nokushisela;
③Ishidi lensimbi enama-electro-galvanized.Ishidi lensimbi elakhiwe ngendlela ye-electroplating linokusebenza okuhle.Kodwa-ke, ukugqoka kuncane, futhi ukumelana nokugqwala akukuhle njengeshidi elishisayo lokucwilisa;
④Ishidi lensimbi elinothayela elinohlangothi olulodwa nohlangothi olukabili.Ishidi lensimbi eliseceleni elilodwa liwumkhiqizo okhandiwe ohlangothini olulodwa kuphela.Ekushiseleni, ekudwebeni, ekwelapheni okunqanda ukugqwala, ekucubunguleni, njll., kunokuvumelana nezimo kangcono kuneshidi elinamacele amabili eliyisithako.Ukuze unqobe ukushiyeka kwe-zinc engagcotshiwe ngakolunye uhlangothi, kunolunye uhlobo lweshidi likathayela elifakwe ungqimba omncane we-zinc ngakolunye uhlangothi, okungukuthi, ishidi elihlukanisayo eliphindwe kabili;
⑤I-alloy neshidi lensimbi eliyinhlanganisela.Yenziwe nge-zinc nezinye izinsimbi ezifana ne-aluminium, i-lead, i-zinc, njll. ukwenza ama-alloys noma ngisho namapuleti ensimbi ayinhlanganisela.Lolu hlobo lwepuleti yensimbi alugcini nje ngokusebenza kahle kakhulu kokugqwala, kodwa futhi lunokusebenza okuhle kokumboza;
Ngaphezu kwalezi zinhlobo ezinhlanu ezingenhla, kukhona amashidi ensimbi anombala, amashidi ensimbi anathathisiwe aphrintiwe, namashidi ensimbi enziwe ngelayini e-PVC.Kodwa okwamanje okuvame ukusetshenziswa kakhulu kuseyishidi le-hot-dip galvanized.
Okwesine: Ipulasitiki
Ngenxa yokuthi wenziwe ngepulasitiki, ubizwa ngokuthi umgqomo kadoti wepulasitiki.Ukwakheka: i-high-density polyethylene HDPE noma i-polypropylene PP polypropylene amapulasitiki amasha amabili amasha.
Izici:
(1) Ukumelana ne-Acid, ukumelana ne-alkali, ukumelana nokugqwala kanye nokumelana nesimo sezulu esinamandla;
(2) Umklamo oyindilinga wekhona lechweba lokudiliva uphephile futhi awunanzuzo;
(3) Indawo engaphezulu ibushelelezi futhi ihlanzekile, inciphisa izinsalela zikadoti futhi kulula ukuyihlanza;
(4) Ingakhelwa phezu kwelinye, elungele ukuhamba futhi yonge indawo nezindleko;
(5) Ingasetshenziswa ngokujwayelekile phakathi kwezinga lokushisa elingu -30℃~65℃;
(6) Kunezinhlobonhlobo zemibala ongakhetha kuzo, engafaniswa ngokwezidingo zokuhlukaniswa;
(7) Isetshenziswa kabanzi ezindaweni ezehlukene, futhi ingasetshenziselwa ukuqoqwa kukadoti, njengempahla, imboni, ukuthuthwa kwendle, njll.
Inzuzo:
Amathini kadoti epulasitiki alula ukuwenza futhi enziwe ngezinto ezonga amandla.Ekusetshenzisweni, akugcini nje ukunciphisa izindleko eziningi, kodwa futhi kunokubonakaliswa okuphelele kokuthuthukiswa kwempilo yesevisi.Amathini kadoti epulasitiki nawo anombukiso omuhle wokuhlanza okwengeziwe.Sijwayele ukulahla udoti emgqonyeni kadoti.Ezinganeni eziningi manje, izophinde ibe nokubaluleka okungcono kwezemfundo, okuzokwenza ukuthi isetshenziswe ekusetshenzisweni.Ibonisa indlela ehlukile yokusebenzisa izinto.Ukuhlanzeka kalula futhi kuyinzuzo yamathini kadoti epulasitiki, okubonisa kakhulu umqondo womklamo osebenziseka kalula wamakani kadoti asetshenziswayo.
