irabha ekhloriniweyo

Ngokuphucuka okuqhubekayo kwinqanaba loqoqosho lwaseTshayina, uphuhliso lweshishini loomatshini luya lukhawuleza ngakumbi nangakumbi, kwaye intsimi yezixhobo zokulwa norhwaphilizo ezifunekayo kwishishini loomatshini nayo iqalise ixesha eliphezulu lophuhliso. Inani elikhulu lemveliso eziphucukileyo nezisemgangathweni ezichasene nokugqwala zaqala ukufakwa kwimarike. Ingubo yerabha eneklorini iye yaqatshelwa luninzi lwabasebenzisi ngenxa yokusebenza kwayo okugqwesileyo kwaye ivelele kukhuphiswano olukhulu lwemarike. Ukususela ngeminyaka yoo-1960, iingubo zerabha ezineklorini zisetyenziswe kakhulu ekwakhiweni kweenqanawa, kwiikhonteyina, kwizibonelelo zokugcina amanzi, kwi-petrochemical nasekwakhiweni kwamandla njengengubo exhasa ukubola kwamazinyo, kwaye idlala indima ebalulekileyo kwinkqubo yophuhliso loqoqosho.
Idatha efanelekileyo ibonisa ukuba ii-chlorine rabha ezifakwe i-chlorine zithatha iipesenti ezimbini ukuya kwezintathu kuphela kwimarike yee-anti-corrosion coatings iyonke. Abasebenzisi abaninzi abanalo ulwazi olunzulu ngee-chlorine rabha ezifakwe i-chlorine, ingakumbi inani elincinci labavelisi ukuze balandele iimfuno zoqoqosho, kunye nezinye iikhompawundi ze-chlorine ezingabizi kakhulu ezithatha indawo yezinto eziqhelekileyo zee-chlorine rabha ezifakwe i-chlorine, nto leyo ephazamisa imarike, kodwa ikwachaphazele nophuhliso lwee-chlorine rabha ezifakwe i-chlorine. Ukuze kuphuculwe ukuqonda uninzi lwabasebenzisi bee-chlorine rabha ezifakwe i-chlorine coat, ukukhuthaza ukukhuthazwa nokusetyenziswa kwee-chlorine rabha ezifakwe i-chlorine, kunye nokuphucula umgangatho wophuhliso lweshishini le-coating laseTshayina, ngoku umbhali ngokusekelwe kuphando lwexesha elide, iipropati ezisisiseko zee-chlorine rabha ezifakwe i-chlorine, ukuhlelwa, ukusetyenziswa kunye nokunye okuqulathweyo ziyaziswa, ngethemba lokunceda uninzi lwabasebenzisi bee-chlorine rabha ezifakwe i-chlorine.

Isishwankathelo sengubo yerabha enekhlorini

Irabha eklorini eyenziwe nge-resin yerabha eklorini eyenziwe ngerabha yendalo okanye irabha yokwenziwa njengezinto eziluhlaza njenge-matrix resin, ize emva koko ibe nezinto ezincedisayo kunye nezinyibilikisi ezifanelekileyo. I-resin yerabha eklorini ine-molecular saturation ephezulu, akukho polarity icacileyo yeebhondi ze-molecular, ulwakhiwo oluqhelekileyo kunye nozinzo oluhle kakhulu. Ngokwembono yembonakalo, i-resin yerabha ekloriniweyo yi-white powder solid, ayinatyhefu, ayinancasa, ayinakucaphuka. I-chloriniated raber coatings ingasetyenziswa ngokuguquguquka, kunye noluhlu olubanzi lwezicelo, kwaye ingasetyenziswa kunye neendidi ezahlukeneyo zepigments njenge-primer, ipeyinti ephakathi okanye ipeyinti ephezulu. Phakathi kwazo, eyona isetyenziswa kakhulu isetyenziswa njenge-topcoat yokufanisa i-coatings. Ngokutshintsha i-resin yerabha ekloriniweyo kunye nezinye i-resin, iintlobo ngeentlobo zeempawu zinokufunyanwa okanye ziphuculwe ukuze kufezekiswe isiphumo esikhulu se-coating.

iipropati zokwambathisa irabha enekhlorini

1. Iingenelo zepeyinti yerabha enekhlorini

1.1 Ukumelana okuphakathi okugqwesileyo kunye nokumelana nemozulu
Emva kokuba irabha eneklorini yenziwe, iibhondi zemolekyuli zeresin kumaleko wepeyinti zibotshelelwe ngokuqinileyo, kwaye isakhiwo semolekyuli sizinzile kakhulu. Ngenxa yesi sizathu, umaleko wepeyinti yerabha eneklorini eneklorini unokumelana okuhle kwemozulu kunye nokumelana okuhle kakhulu namanzi, i-asidi, i-alkali, ityuwa, i-ozone kunye nezinye izinto. Ukungenela kwamanzi kunye negesi yi-10 ekhulwini kuphela kwezinto ze-alkyd. Ngokwembono yeminyaka emininzi yokusebenza, umaleko wepeyinti yerabha eneklorini unekumelana okukhulu ne-aliphatic solvents, ioyile ecociweyo kunye neoyile yokuthambisa, kwaye ungasetyenziselwa unyango lokulwa nokungunda kwiindawo ezifumileyo, kwaye ukumelana nokukrazula kwe-cathode kuphezulu kakhulu.
1.2 Ukunamathela okuhle, ukuhambelana okuhle nezinye iintlobo zokugquma
Ingubo yerabha eluhlaza esetyenziswa njenge-primer inomlinganiselo omkhulu wokunamathela kwizinto zentsimbi. Njengepeyinti ephezulu, ipeyinti ephakathi ingasetyenziswa nge-epoxy resin, i-polyurethane kunye nezinye iintlobo ze-primer, isiphumo siphezulu kakhulu. Ingubo yerabha ene-chlorine kulula ukuyilungisa, ungasebenzisa i-chlorine raber coating ukuze uphinde uyipeyinte, ungasebenzisa ne-acrylic, ii-solvent-based coating ezahlukeneyo kunye nazo zonke iintlobo zeengubo ezichasene nokungcola ukuze kulungiswe ibrashi.
1.3 Ulwakhiwo olulula nolulula
Ingubo yerabha eneklorini yingubo yento enye, ixesha lokwenziwa kwefilimu lifutshane kakhulu, isantya sokwakha sikhawuleza. Iimfuno zobushushu bokwakha i-coating yerabha eneklorini zibanzi kakhulu, kwaye zingakhiwa ukusuka kwi--5 degrees ukuya kwi-40 degrees ngaphezu kwe-zero. Ubungakanani be-diluent eyongeziweyo ngexesha lokwakha buncinci kakhulu, kwaye akukho diluent inokongezwa, nto leyo enciphisa ukuguquguquka kwezinyibilikisi zendalo kwaye inokusebenza kakuhle kokusingqongileyo. Ingubo yerabha eneklorini inokusetyenziswa ngokuthe ngqo kumphezulu wamalungu ekhonkrithi, kwaye inokumelana okuhle kwe-alkali. Xa isetyenziswa kwimisebenzi yomgca wendibano, indlela "emanzi ngokuchasene nokumanzi" ingasetyenziselwa ukutshiza, iphucula kakhulu ukusebenza kakuhle kwemveliso.

2. Iintsilelo kunye nokusilela kwengubo yerabha enekhlorini

2.1 Umbala omnyama werabha eklorini, ukukhanya okungekho ngqiqweni, kulula ukufunxa uthuli, umbala awuhlali ixesha elide, awunakusetyenziselwa ipeyinti yokuhombisa;
2.2 Ukumelana nobushushu kwengubo kubuthathaka kakhulu emanzini. Kwiindawo ezifumileyo, ukumelana nobushushu kuncipha kakhulu. Ubushushu bokubola kobushushu kwindawo eyomileyo yi-130 ° C, kwaye ubushushu bokubola kobushushu kwindawo efumileyo yi-60 ° C kuphela, nto leyo ekhokelela kwindawo engasetyenziswa kakhulu yengubo yerabha enekhlorini, kwaye ubushushu obukhulu bendawo esetyenziswayo abunakudlula kwi-70 ° C.
2.3 Ipeyinti yerabha eneklorini inomxholo ophantsi oqinileyo kunye nobukhulu befilimu ebhityileyo. Ukuqinisekisa ubukhulu befilimu, kufuneka itshizwe ngokuphindaphindiweyo, nto leyo echaphazela ukusebenza kakuhle kwemveliso;
2.4 Ingubo yerabha eneklorini ayinyamezeli kakuhle izinto ezinuka kamnandi kunye nezinye iintlobo zezinyibilikisi. Ingubo yerabha eneklorini ayinakusetyenziswa njengengubo yokukhusela udonga lwangaphakathi kwiindawo apho kunokubakho izinto ezinganyamezeliyo, ezifana nemibhobho yeekhemikhali, izixhobo zokuvelisa kunye neetanki zokugcina. Kwangaxeshanye, ingubo yerabha eneklorini ayinakusekelwa ixesha elide kumafutha ezilwanyana kunye namafutha emifuno;

indlela yophuhliso lwengubo yerabha enekhlorini

1. Uphando malunga nokuguquguquka kwefilimu yepeyinti Iingubo zerabha ezifakwe iklorini zisetyenziswa kakhulu kunyango lokulwa nokugqwala kweemveliso zesinyithi.

Ekubeni umthamo weemveliso zesinyithi uza kutshintsha kakhulu xa ubushushu butshintsha, ukuqinisekisa ukuba umgangatho wefilimu yepeyinti awuchaphazeleki kakhulu xa isiseko sikhula kwaye sincipha, irabha egqunywe ngechlorine kufuneka ibe nokuguquguquka okuhle ukunciphisa uxinzelelo oluvela xa isiseko sikhula kakhulu. Okwangoku, indlela ephambili yokuphucula ukuguquguquka kwepeyinti yerabha egqunywe ngechlorine kukongeza iparafini egqunywe ngechlorine. Ukusuka kwidatha yovavanyo, xa isixa sisonke separafini egqunywe ngechlorine sifikelela kwi-20% ye-resin yerabha egqunywe ngechlorine, ukuguquguquka kwefilimu kunokufikelela kwi-1 ~ 2mm.

2. Uphando ngetekhnoloji yokuguqula
Ukuze kuphuculwe iipropati zefilimu yokupenda nokwandisa uluhlu lokusetyenziswa kwezambatho zerabha ezine-chlorine, abaphandi benze uphando oluninzi lokuguqula kwiingubo zerabha ezine-chlorine. Ngokusebenzisa irabha ene-chlorine ene-alkyd, i-epoxy ester, i-epoxy, i-coal tar pitch, i-thermoplastic acrylic acid kunye ne-vinyl acetate copolymer resin, iingubo ezidityanisiweyo zenze inkqubela ebonakalayo ekuguquguqukeni kwefilimu yokupenda, ukumelana nemozulu kunye nokuxhathisa ukugqwala, kwaye kwakhuthaza uphuhliso lweshishini lokugquma elikhusela ukugqwala kakhulu.

3. Funda ngomxholo oqinileyo weengubo
Umxholo oqinileyo werabha efakwe iklorini uphantsi kwaye ubukhulu befilimu buncinci, ukuze kuhlangatyezwane neemfuno zobukhulu befilimu, kuyimfuneko ukwandisa inani lamaxesha okuxubha kunye nokuchaphazela ukusebenza kakuhle kwemveliso. Ukuze kusonjululwe le ngxaki, kuyimfuneko ukuqala ngengcambu kwaye kuphuculwe umxholo oqinileyo wepeyinti. Ekubeni irabha efakwe iklorini kunzima ukuyifumisa, umxholo oqinileyo unokuncitshiswa kuphela ukuqinisekisa ukusebenza kolwakhiwo. Okwangoku, umxholo oqinileyo werabha efakwe iklorini uphakathi kwe-35% kunye ne-49%, kwaye umxholo we-solvent uphezulu, ochaphazela ukusebenza kwendalo kwerabha.

Iindlela eziphambili zokuphucula umxholo oqinileyo weengubo zerabha ezifakwe iklorini kukulungisa ixesha lokungena kwegesi yeklorini kunye nokulawula ubushushu bokusabela xa kuveliswa i-resin ngerabha efakwe iklorini.
