pendi yesimbi yekuputira chimiro

Simbi rudzi rwezvinhu zvekuvaka zvisingatsvi, ine hunhu hwekudengenyeka kwenyika, kukotama nezvimwe. Mukushanda kwayo, simbi haingogone kuwedzera mutoro wezvivakwa chete, asiwo inosangana nezvinodiwa zvekushongedza zvivakwa. Inodzivisawo zvikanganiso izvo zvinhu zvekuvaka zvakaita sekongiri zvisingagoni kukotama nekutambanudza. Saka, simbi yave ichifarirwa neindasitiri yekuvaka, ine nhurikidzwa imwe chete, ine nhurikidzwa dzakawanda, zvivako zvakakura, mafekitori, matura, makamuri ekumirira, dzimba dzekubuda nesimbi dzimwe zvakajairika. Kuti tidzidze kubva kune mumwe nemumwe, kushandiswa kwekuputira kwesimbiuyesimbi yekutangapendi inokosha.

Kupatsanurwa kwezvipfeko zvesimbi zvechimiro

Machira esimbi ane mhando mbiri dzemachira esimbi asingatsvi uye machira esimbi anodzivirira ngura.
(A) pendi yesimbi isingatsvi

1. Kuputira kwakatetepa zvikuru kusingatsvi

Kuputira kwesimbi yakatetepa zvikuru kusingapisi kunoreva ukobvu hwejira iri mukati me3 mm (kusanganisira 3 mm), mhedzisiro yekushongedza yakanaka, inogona kukura pakupisa kwakanyanya, uye muganho wekudzivirira moto unowanzo kuve mukati memaawa maviri kubva pakuputira kwesimbi isingapisi. Rudzi urwu rwejira rinodzivirira moto rinowanzo kuve sisitimu inobva kune zvinonyungudutsa, ine simba rekubatanidza rakakwirira, inodzivirira mamiriro ekunze akanaka uye inodzivirira mvura, inoenzana zvakanaka, ine hunhu hwakanaka hwekushongedza; Kana ikapiswa, inokura zvishoma nezvishoma uye inopupuma furo kuti igadzire layer yakasimba uye yakasimba isingapisi. Layer isingapisi ine hunhu hwakasimba husingapisi, inononoka kukwira kwekupisa kwesimbi uye inodzivirira zvinobudirira zvikamu zvesimbi. Kuvakwa kwejira resimbi rakatetepa zvakanyanya rinogona kupfapfaidzwa, kukweshwa kana kumonerwa, rinowanzo shandiswa muzvinodiwa zvemuganhu wekudzivirira moto mukati memaawa maviri pachivako chesimbi. Kwave nemarudzi matsva ezvipfeko zvesimbi zvakatetepa zvikuru zvisingatsve zvine simba rekudzivirira moto kwemaawa maviri kana kupfuura, izvo zvinonyanya kushandisa polymethacrylate kana epoxy resin ine chimiro chakakosha uye amino resin, chlorinated paraffin se base binder, ine high polymerization degree ammonium polyphosphate, dipentaerythritol, melamine senzira inodzivirira moto. Titanium dioxide, wollastonite nezvimwe zvinhu zvisingagadzirisike zvinowedzerwa mu 200# solvent oil se solvent composite. Zvivako zvakasiyana-siyana zvesimbi dzakareruka, magridi, nezvimwewo, zvinoshandisa rudzi urwu rwependi inodzivirira moto kudzivirira moto. Nekuda kwezvipfeko zvakatetepa zvakanyanya zvemhando iyi yezvipfeko zvinodzivirira moto, kushandiswa kwezvipfeko zvakatetepa uye zvakatetepa zvesimbi zvakaderera zvakaderera zvikuru, izvo zvinoderedza mari yese yeprojekiti, uye zvinoita kuti chimiro chesimbi chiwane dziviriro inoshanda yemoto, uye mhedzisiro yekudzivirira moto yakanaka kwazvo.

2. Kuputira kunodzivirira moto kwechimiro chesimbi chakatetepa

Kuputira kwesimbi yakatetepa kusingapisi kunoreva kuputira kwesimbi kusingapisi ukobvu hwayo hwakakura kupfuura 3mm, pasi pe7mm kana kuti hwakaenzana, kune mhedzisiro yekushongedza, kunokura uye kukora pakupisa kwakanyanya, uye muganho wekudzivirira moto uri mukati memaawa maviri. Rudzi urwu rwekuputira kusingapisi kwesimbi runowanzo umbwa nepolymer yakakodzera inobva mumvura sehwaro hwechinhu, uye zvinozoumbwa nehurongwa hwakabatana hwezvinodzivisa moto, zvinowedzera zvinodzivirira moto, fibers dzinodzivirira moto, nezvimwewo, uye musimboti wayo wekudzivirira moto wakafanana nerudzi rwakatetepa kwazvo. Kune rudzi urwu rwekuputira kusingapisi, polymer inobva mumvura inodiwa kusarudzwa inofanira kunge yakabatana zvakanaka, yakasimba uye inodzivirira mvura kune substrate yesimbi. Kushongedzwa kwayo kuri nani pane kuputira kwakakora kusingapisi, kushoma pane kuputira kusingapisi kwesimbi kwakatetepa, uye muganho wekudzivirira moto uri mukati memaawa maviri. Nokudaro, inowanzoshandiswa mumapurojekiti ekudzivirira moto echivako chesimbi ane muganho wekudzivirira moto uri pasi pemaawa maviri, uye kuvaka kwespray kunowanzo shandiswa. Mune imwe nguva, yaitora chikamu chikuru, asi nekubuda kwemachira esimbi akatetepa zvikuru asingatsvi, mugove wayo wemusika wakatsiviwa zvishoma nezvishoma.

3. Kuputira kwesimbi gobvu isingatsvi

Chimiro chesimbi chakakora chinodzivisa moto chinoreva kuti ukobvu hwechidziro hwakakura kupfuura 7 mm, husingasviki kana kuti hwakaenzana ne45 mm, pamusoro pegranular, hushoma, kudziya kwakaderera, muganho wekudzivirira moto weanopfuura maawa maviri esimbi chidziro chinodzivisa moto. Sezvo kuumbwa kwezvipfeko zvinodzivisa moto kwakakora kuri kazhinji zvinhu zvisina organic, kushanda kwaro mumoto kwakagadzikana uye mhedzisiro yekushandiswa kwenguva refu yakanaka, asi zvidimbu zvezvikamu zvaro zvependi zvakakura, chitarisiko chechidziro hachina kuenzana, zvichikanganisa runako rwechivako chose, saka chinoshandiswa zvakanyanya pakugadzira zvinhu zvakavanzwa. Rudzi urwu rwechidziro chinodzivisa moto chinoshandisa pamusoro pezvinhu zviri mumoto, hushoma, kudziya kwakaderera kana kupinza kupisa kwezvinhu zviri mupurasitiki, izvo zvinononotsa kukwira kwekupisa kwesimbi uye zvinodzivirira simbi. Rudzi urwu rwekuputira rusingatsve runogadzirwa nechinhu chisina kutsvedza chakakodzera (senge girazi remvura, silica sol, aluminium phosphate, simende isingatsvedzere, nezvimwewo), Ipapo inosanganiswa nezvinhu zvisingatsvedzere zveadiabatic aggregate (senge perlite yakawedzerwa, vermiculite yakawedzerwa, sea bouldering, floating beads, fly ash, nezvimwewo), zvinowedzera zvinodzivirira moto, makemikari nezvinhu zvinosimbisa (senge aluminium silicate fiber, rock wool, ceramic fiber, glass fiber, nezvimwewo) uye zvinozadza, nezvimwewo, zvine mabhenefiti emutengo wakaderera. Kupfapfaidza kunowanzo shandiswa mukuvaka, uko kwakakodzera zvivakwa zvesimbi zvemukati nekunze zvine miganhu yekudzivirira moto inopfuura maawa maviri, zvivakwa zvesimbi zvese uye zvivakwa zvesimbi zvefekitori zvine nhurikidzwa dzakawanda. Semuenzaniso, muganho wekudzivirira moto wemakoramu ezvivakwa zvehurumende, zvivakwa zvemaindasitiri nezvivakwa zvehurumende zvinotsigira makoramu akawanda zvinofanirwa kusvika maawa matatu, uye kobvu rekudzivirira moto rinofanira kushandiswa kuzvidzivirira.

(2) pendi yesimbi inorwisa ngura

Kuvhara ngura kwechimiro chesimbi imhando itsva yekufukidza ngura kwechimiro chesimbi yakagadzirwa zvichibva pakupenda kunodzivirira ngura kusingapindi mafuta. Pendi yakakamurwa kuita mhando mbiri dzependi yekutanga nependi yepamusoro, pamusoro pezvo, huwandu hwayo hwekushandiswa hwakakura, uye pendi inogona kugadziriswa kune mavara akasiyana zvichienderana nezvinodiwa. Kuvhara ngura kwechimiro chesimbi kwakakodzera tsvina, mvura yegungwa, mvura yeindasitiri, peturu, parafini, mafuta edhiziri, gasi nezvimwe matangi ekuchengetera, mafuta, mapaipi egasi, mabhiriji, magridhi, michina yemagetsi nemhando dzese dzemichina yemakemikari kudzivirira ngura, inogona zvakare kushandiswa pakuchengetedza ngura munzvimbo dzekongiri.

Chekutanga, vandudza hunhu hwesimbi: ndiko kuti, kurapwa kwe alloy:

Nyanzvi zhinji dzekune dzimwe nyika dzakadzidza nezvesimba rezvinhu zvakasiyana-siyana zvinosanganisa simbi pakurwisa ngura mumvura yegungwa. Zvakaonekwa kuti simbi dzemhando ye alloy dzakavakirwa paCr, Ni, Cu, P, Si uye rare earth dzine hunhu hwakanaka hwekudzivirira ngura, uye nekuda kweizvi, simbi dzakawanda dzinodzivirira ngura mumvura yegungwa dzakagadzirwa. Zvisinei, nekuda kwezvikonzero zvehupfumi netekinoroji, zvinhu zvataurwa pamusoro apa hazvishandiswi zvakanyanya musimbi dzinodzivirira ngura mumvura yegungwa.

Chechipiri, kuumbwa kwechikamu chinodzivirira: ndiko kuti, kufukidza chikamu chinodzivirira chisina simbi kana simbi:

Rutivi rwesimbi runonyanya kushandiswa pakurapa simbi yakaputirwa ne phosphate, oxidation uye passivation. Rutivi rwesimbi rusingapindi simbi runonyanya kuputirwa nependi, purasitiki, enamel, mineral grease nezvimwewo pamusoro pesimbi kuti pave nerutivi rwekudzivirira. Chinangwa cherutivi urwu rwekudzivirira ndechekuparadzanisa zvinhu zvepasi kuti zvisabatane nemvura yegungwa, pachinzvimbo chekubatana nemvura yegungwa, nokudaro zvichigadzira dziviriro.
