upende wokupenda isakhiwo sensimbi

Insimbi iwuhlobo lwezinto zokwakha ezingashi, inezici zokuzamazama komhlaba, ukugoba nezinye. Ekusetshenzisweni okungokoqobo, insimbi ayikwazi nje ukwandisa umthamo womthwalo wezakhiwo, kodwa futhi ihlangabezana nezidingo zobuhle bokuklama izakhiwo. Iphinde igweme amaphutha izinto zokwakha ezifana nokhonkolo ezingenakugoba futhi zinwetshwe. Ngakho-ke, insimbi iye yathandwa yimboni yokwakha, enesitezi esisodwa, enezitezi eziningi, izakhiwo eziphakeme, amafektri, izindawo zokugcina impahla, amakamelo okulinda, amahholo okusuka kanye nezinye izinsimbi kuvamile. Ukuze sifundane, ukusetshenziswa kweizembozo zesakhiwo sensimbifuthiisisekelo sensimbiupende ubalulekile.

Ukuhlukaniswa kwezembozo zesakhiwo sensimbi

Izembozo zesakhiwo sensimbi ikakhulukazi zinezinhlobo ezimbili zezembozo ezingashisi zesakhiwo sensimbi kanye nezembozo zokulwa nokugqwala zesakhiwo sensimbi.
(A) upende ongashiswa yisakhiwo sensimbi

1. Ukugqoka okungashisi kwesakhiwo okunciphile kakhulu

Isembozo esingashisi sesakhiwo sensimbi esinciphile kakhulu sibhekisela ekujikeni kwesembozo ngaphakathi kwama-3 mm (kufaka phakathi ama-3 mm), umphumela wokuhlobisa muhle, unganda ekushiseni okuphezulu, futhi umkhawulo wokumelana nomlilo ngokuvamile ungaphakathi kwamahora ama-2 kusukela ekumbozweni okungashisi kwesakhiwo sensimbi. Lolu hlobo lwesembozo esivimbela umlilo sesakhiwo sensimbi ngokuvamile luyisistimu esekelwe ku-solvent, enamandla okubopha aphezulu, ukumelana nesimo sezulu okuhle kanye nokumelana namanzi, ukulingana okuhle, izici ezinhle zokuhlobisa; Uma ishiswa, iyanda kancane kancane futhi igwebu ukuze yakhe isembozo esiqinile nesiqinile esingashisi. Isembozo esingashisi sinamandla okumelana nomlilo, okubambezela ukukhuphuka kwezinga lokushisa lensimbi futhi kuvikela ngempumelelo izingxenye zensimbi. Ukwakhiwa kwesembozo esingashisi sesakhiwo sensimbi esinciphile kakhulu kungafuthwa, kubhulashwe noma kugoqwe, ngokuvamile kusetshenziswa ezidingweni zomkhawulo wokumelana nomlilo zingakapheli amahora ama-2 esakhiweni sensimbi yesakhiwo. Kube nezinhlobo ezintsha zezingubo zokuvikela umlilo ezakhiwe ngensimbi ezincane kakhulu ezinokumelana nomlilo amahora ama-2 noma ngaphezulu, ezisebenzisa kakhulu i-polymethacrylate noma i-epoxy resin enesakhiwo esikhethekile kanye ne-amino resin, i-chlorinated paraffin njengesisekelo se-binder, ene-polymerization degree ephezulu ye-ammonium polyphosphate, i-dipentaerythritol, i-melamine njengohlelo lokuvimbela umlilo. I-Titanium dioxide, i-wollastonite nezinye izinto ezingaphili ezingaphili zengezwa ku-200# solvent oil njenge-solvent composite. Izakhiwo zensimbi ezilula ezahlukahlukene, ama-grid, njll., zisebenzisa lolu hlobo lopende olungashisi umlilo ukuze kuvikelwe umlilo. Ngenxa yokugqoka okuncane kakhulu kwalolu hlobo lokugqoka okungashisi umlilo, ukusetshenziswa kokugqoka okuqinile nokuncane kwesakhiwo sensimbi kuncishiswe kakhulu, okunciphisa izindleko eziphelele zephrojekthi, futhi kwenza isakhiwo sensimbi sithole ukuvikelwa komlilo okusebenzayo, futhi umphumela wokuvikela umlilo muhle kakhulu.

2. Ukugqoka okuvimbela umlilo kwesakhiwo sensimbi encane

Isembozo esingashiswa yisakhiwo sensimbi esimbozwe kancane sibhekisela esenzweni esingashiswa yisakhiwo sensimbi esinobukhulu bokumboza obukhulu kuno-3mm, obungaphansi noma obulingana no-7mm, bunomphumela othile wokuhlobisa, buyanda futhi buqine ekushiseni okuphezulu, futhi umkhawulo wokumelana nomlilo ungaphakathi kwamahora ama-2. Lolu hlobo lwesembozo esingashiswa yimlilo sesakhiwo sensimbi ngokuvamile lwakhiwe yi-polymer efanelekile esekwe emanzini njengezinto eziyisisekelo, bese luhlanganiswa nohlelo oluhlanganisiwe lwezinto ezivimbela umlilo, izithasiselo ezivimbela umlilo, imicu engashiswa yimlilo, njll., futhi isimiso salo sokuvimbela umlilo sifana nohlobo olunciphile kakhulu. Kulolu hlobo lwesembozo esingashiswa yimlilo, i-polymer esekwe emanzini edingekayo ukukhethwa kumele ibe nokunamathela okuhle, ukuqina kanye nokumelana namanzi ku-substrate yensimbi. Ukuhlobisa kwayo kungcono kunezembozo ezingashiswa yimlilo eziqinile, ezingaphansi kwezembozo ezingashiswa yisakhiwo sensimbi ezinciphile kakhulu, kanti umkhawulo wokumelana nomlilo ojwayelekile ungaphakathi kwamahora ama-2. Ngakho-ke, ivame ukusetshenziswa kumaphrojekthi okuvikela umlilo wesakhiwo sensimbi anomkhawulo wokumelana nomlilo ongaphansi kwamahora ama-2, futhi ukwakhiwa kwesifutho kuvame ukusetshenziswa. Esikhathini esithile, yayithatha ingxenye enkulu, kodwa ngokuvela kwezembozo zesakhiwo sensimbi ezincane kakhulu ezingashisi, isabelo sayo semakethe sashintshwa kancane kancane.

3. Isembozo esingashisi sesakhiwo sensimbi ejiyile

Isembozo esivimba umlilo sesakhiwo sensimbi esijiyile sibhekisela ekutheni ubukhulu besembozo bungaphezu kuka-7 mm, ngaphansi noma okulingana no-45 mm, ubuso obuyi-granular, ukuminyana okuncane, ukuhanjiswa kokushisa okuphansi, umkhawulo wokumelana nomlilo wesembozo esivimba umlilo sesakhiwo sensimbi esingaphezu kwamahora ama-2. Njengoba ukwakheka kwesembozo esivimba umlilo esijiyile kuyizizinto ezingaphili, ukusebenza kwaso komlilo kuzinzile futhi umphumela wokusetshenziswa kwesikhathi eside muhle, kodwa izinhlayiya zezingxenye zaso zopende zinkulu, ukubukeka kwesembozo akulingana, kuthinta ubuhle besakhiwo sonke, ngakho-ke sisetshenziswa kakhulu ekubunjweni okufihliwe kwesakhiwo. Lolu hlobo lwesembozo esivimba umlilo lusebenzisa ubuso obuyi-granular bezinto ezisemlilweni, ukuminyana kuncane, ukuhanjiswa kokushisa kuphansi noma ukumuncwa kokushisa kwezinto ezisesembozweni, okubambezela ukukhuphuka kwezinga lokushisa lensimbi futhi kuvikele insimbi. Lolu hlobo lokugqoka okungashiswa umlilo lwenziwe nge-binder efanelekile ye-inorganic (njengengilazi yamanzi, i-silica sol, i-aluminium phosphate, usimende ongaphikisi, njll.), Bese ixutshwa nezinto zokuhlanganisa ze-adiabatic ezilula ze-inorganic (njenge-perlite enwetshiwe, i-vermiculite enwetshiwe, i-sea bouldering, ubuhlalu obuntantayo, umlotha ondizayo, njll.), izithasiselo ezivimbela umlilo, izinto zamakhemikhali nezinto zokuqinisa (njenge-aluminium silicate fiber, uboya bedwala, i-ceramic fiber, i-glass fiber, njll.) kanye nama-filler, njll., anezinzuzo zezindleko eziphansi. Ukufutha kuvame ukusetshenziswa ekwakheni, okufanelekela izakhiwo zensimbi ezifihliwe zangaphakathi nezangaphandle ezinemikhawulo yokumelana nomlilo engaphezu kwamahora ama-2, izakhiwo zensimbi ezinde ezinde kanye nezakhiwo zensimbi zasefektri ezinezitezi eziningi. Isibonelo, umkhawulo wokumelana nomlilo wamakholomu ezakhiwo zomphakathi eziphakeme, izakhiwo zezimboni nezakhiwo zomphakathi ezijwayelekile ezisekela amakholomu anezingqimba eziningi kufanele ufinyelele amahora ama-3, futhi ukugqoka okungashiswa umlilo okujiyile kufanele kusetshenziswe ukuzivikela.

(2) upende wesakhiwo sensimbi ovimbela ukugqwala

Upende ovimbela ukugqwala wesakhiwo sensimbi uhlobo olusha lopende ovimbela ukugqwala wesakhiwo sensimbi olwakhiwe ngesisekelo sopende ovimbela ukugqwala ongamelana namafutha. Upende uhlukaniswe izinhlobo ezimbili zopende we-primer kanye nopende ophezulu, ngaphezu kwalokho, ububanzi bokusetshenziswa kwawo bubanzi, futhi upende ungalungiswa ngemibala ehlukahlukene ngokuya ngezidingo. Upende ovimbela ukugqwala wesakhiwo sensimbi ufanelekela indle, amanzi olwandle, amanzi ezimboni, uphethiloli, uphethiloli, uphethiloli wejethi yedizili, igesi kanye nezinye izitolo, uwoyela, amapayipi egesi, amabhuloho, amagridi, imishini yamandla kanye nazo zonke izinhlobo zemishini yamakhemikhali ukuvikela ukugqwala, kungasetshenziswa futhi ezindaweni zekhonkrithi ukuvikela ukugqwala.

Okokuqala, thuthukisa uhlobo lwensimbi: okungukuthi, ukwelashwa kwe-alloy:

Izazi eziningi zakwamanye amazwe ziye zafunda ithonya lezinto ezahlukahlukene zokuhlanganisa ekuphikiseni ukugqwala kwensimbi emanzini olwandle. Kutholakale ukuthi izinsimbi ze-alloy ezisekelwe ku-Cr, Ni, Cu, P, Si kanye nomhlaba ongavamile zinezakhiwo ezinhle kakhulu zokulwa nokugqwala, futhi ngenxa yalokhu, kuye kwasungulwa uchungechunge lwezinsimbi ezimelana nokugqwala emanzini olwandle. Kodwa-ke, ngenxa yezizathu zomnotho nezobuchwepheshe, lezi zinto ezingenhla azisetshenziswa kabanzi ezinsimbini ezimelana nokugqwala emanzini olwandle.

Okwesibili, ukwakheka kwesendlalelo esivikelayo: okungukuthi, ukumboza isendlalelo esivikelayo esingeyona insimbi noma insimbi:

Ingqimba yokuvikela yensimbi isetshenziswa kakhulu ekuphatheni i-phosphate, i-oxidation kanye ne-passivation yensimbi eboshiwe. Ingqimba yokuvikela engeyona eyensimbi ngokuyinhloko iwukumbozwa kopende, ipulasitiki, i-enamel, amafutha amaminerali nokunye ebusweni bensimbi ukuze kwakhiwe ungqimba lokuvikela. Inhloso yalezi zingqimba ezimbili zokuvikela ukuhlukanisa izinto eziyisisekelo ekuthinteni amanzi olwandle, esikhundleni sokusabela emanzini olwandle, ngaleyo ndlela kwakhiwe isivikelo.
