irabha eneklorini yokugquma

Ngophuculo oluqhubekayo lwenqanaba loqoqosho lwaseTshayina, uphuhliso loshishino loomatshini luya lukhula ngokukhawuleza nangokukhawuleza, kwaye intsimi yezinto ezichasene norhwaphilizo eziyimfuneko kushishino loomatshini iye yangenisa ixesha lencopho yophuhliso. Inani elikhulu lentsebenzo ephucukileyo, iimveliso ezichasene ne-corrosion ezisemgangathweni zaqala ukubeka kwimarike. Ukwaleka kwerabha eneklorijini kuye kwaqatshelwa luninzi lwabasebenzisi ngokusebenza kwayo okugqwesileyo kwaye ibalasele kukhuphiswano oluqatha lwemarike. Ukususela kwiminyaka yee-1960, iingubo zerubha ezixutywe ngeklorini zisetyenziswe ngokubanzi ekwakhiweni kweenqanawa, izitya, izibonelelo zokugcina amanzi, i-petrochemical kunye nokwakhiwa kwamandla njengenkxaso yokubola kwamazinyo, kwaye idlala indima ebalulekileyo kwinkqubo yophuhliso loqoqosho.
Idatha efanelekileyo ibonisa ukuba irabha eneklorini yokugquma ibalelwa kwiipesenti ezimbini ukuya kwezintathu kuphela kwimakethi echasene nokubola. Abasebenzisi abaninzi abanalo ukuqonda okunzulu kweerabha ezineklorini zokugquma, ngakumbi inani elincinci labavelisi ukuze balandele umdla wezoqoqosho, kunye nezinye iikhompawundi zeklorini ezinexabiso eliphantsi ukuze zithathe indawo yamacandelo aqhelekileyo eengubo zerabha eklorini, ephazamisa imarike, kodwa ichaphazele nophuhliso lwerabha eklorini. Ukuze kuphuculwe ukuqonda uninzi lwabasebenzisi be-anti-corrosion yokwaleka kwerabha eneklorini, ukukhuthaza ukukhuthaza kunye nokusetyenziswa kwerabha eneklorini, kunye nokuphucula inqanaba lophuhliso loshishino lokwaleka lwaseTshayina, ngoku umbhali ngesiseko sophando lwexesha elide, iipropati ezisisiseko zokwaleka irabha eklorini, ukuhlelwa, ukusetyenziswa kunye nezinye iziqulatho ziyaziswa, ngethemba lokunceda uninzi lwabasebenzisi be-anti-corroro.

Isishwankathelo sokwaleka kwerabha ekloriniweyo

Irabha eneklorini yokwambathisa yenziwe ngerabha ekrwada eveliswe yirubha yendalo okanye irabha yokwenziwa njengento ekrwada njengeresin ye-matrix, emva koko kunye nezinto ezincedisayo ezihambelanayo kunye nezinyibilikisi. I-resin ye-rubber ye-chlorine ine-saturation ephezulu ye-molecular, akukho polarity ecacileyo yeebhondi ze-molecular, isakhiwo esiqhelekileyo kunye nokuzinza okuhle kakhulu. Ukusuka kwindawo yokujonga imbonakalo, i-resin yerabha ekloriniweyo ngumgubo omhlophe oqinileyo, ongenatyhefu, ongenancasa, awucaphuki. Iingubo zerubha zeklorini zingasetyenziswa ngokuguquguqukayo, kunye noluhlu olubanzi lwezicelo, kwaye zingasetyenziselwa ngeentlobo zemibala njenge-primer, ipeyinti ephakathi okanye ipeyinti ephezulu. Phakathi kwazo, eyona nto isetyenzisiweyo isetyenziswa njenge-topcoat yokulinganisa iingubo. Ngokuguqula i-resin ye-rubber e-chlorine kunye nezinye ii-resin, iintlobo ezahlukeneyo zeepropathi zingafumaneka okanye ziphuculwe ukufezekisa umphumo omkhulu wokugubungela.

iipropati zokugquma irabha eklorini

1. Izinto eziluncedo zepeyinti yerabha eklorini

1.1 Ukumelana okubalaseleyo okuphakathi kunye nokumelana nemozulu
Emva kokuba i-rubber ye-rubber ye-chlorine yenziwe, iibhondi ze-molecular ye-resin kwinqanaba lepeyinti ziboshwe ngokuqinileyo, kwaye isakhiwo se-molecular sizinzile kakhulu. Ngesi sizathu, umaleko wepeyinti yerabha eneklorini inokumelana nemozulu elungileyo kunye nokuchasana okugqwesileyo kumanzi, iasidi, ialkali, ityuwa, i-ozone kunye nezinye imidiya. Ukungena kwamanzi kunye negesi yipesenti ezilishumi kuphela zezinto zealkyd. Ngokombono weminyaka emininzi yokusebenza, irabha yepeyinti eklorini inamandla okumelana ne-aliphatic solvents, ioli esulungekileyo kunye ne-oyile yokuthambisa, kwaye ingasetyenziselwa unyango oluchasene nokungunda kwiindawo ezifumileyo, kwaye ukuchasana nokuchithwa kwe-cathode kuphezulu kakhulu.
1.2 Ukubambelela kakuhle, ukuhambelana kakuhle nezinye iintlobo zeengubo
Ingubo yerabha eluhlaza esetyenziswe njenge-primer inomlinganiselo omkhulu wokubambelela kwizinto zetsimbi. Njengepeyinti ephezulu, ipeyinti ephakathi ingasetyenziselwa i-epoxy resin, i-polyurethane kunye nezinye iintlobo ze-primer, umphumo uphezulu kakhulu. Ukufakwa kwerabha eneklorini kulula ukuyilungisa, ungasebenzisa irabha eneklorini ukupeyinta kwakhona, ungasebenzisa i-acrylic, iirabha ezahlukahlukeneyo ezisekelwe kwi-solvent kunye nazo zonke iintlobo ze-anti-fouling yokulungiswa kwebrashi.
1.3 Ulwakhiwo olulula noluluncedo
I-rubber ye-chlorine ye-rubber ye-rubber yecandelo elilodwa, ixesha lokubunjwa kwefilimu lifutshane kakhulu, isantya sokwakha sikhawuleza. Iimfuno zeqondo lokushisa lokwakhiwa kweerubha eziklorini zibanzi, kwaye zinokwakhiwa ukusuka kwi--5 degrees ukuya kwi-40 degrees ngaphezu kwe-zero. Isixa se-diluent esongeziweyo ngexesha lokwakha sincinci kakhulu, kwaye akukho nto inokuthi idibaniswe, enciphisa ukuguquguquka kwe-solvents yezinto eziphilayo kunye nokusebenza kakuhle kokusingqongileyo. Ukwaleka kwerabha ngeklorini kungasetyenziswa ngokuthe ngqo kumphezulu wamalungu ekhonkrithi, kwaye inokumelana nealkali elungileyo. Xa isetyenziswa kwimisebenzi yomgca wendibano, indlela "emanzi ngokuchasene nemanzi" ingasetyenziselwa ukutshiza, iphucula kakhulu impumelelo yemveliso.

2. Iintsilelo kunye neentsilelo zokugquma irabha yeklorini

2.1 Irabha eneklorini yokugquma umbala omnyama, ukukhanya okungahambi kakuhle, kulula ukufunxa uthuli, umbala awunako ixesha elide, awukwazi ukusetyenziselwa ipeyinti yokuhlobisa;
2.2 Ukumelana nokushisa kwengubo kuyingozi kakhulu kumanzi. Kwiindawo ezifumileyo, ukumelana nobushushu kuncipha kakhulu. Iqondo lobushushu lokubola kwe-thermal kwindawo eyomileyo yi-130 ° C, kwaye iqondo lobushushu lokubola kwindawo efumileyo lingama-60 ° C kuphela, nto leyo ekhokelela ekusetyenzisweni okulinganiselweyo kokugquma kwerabha eneklorini, kwaye ubushushu obuphezulu bokusebenzisa imekobume ayinakudlula i-70 ° C.
2.3 Ipeyinti yerabha eneklorijini inomxholo ophantsi oqinileyo kunye nobukhulu befilimu ebhityileyo. Ukuqinisekisa ubukhulu befilimu, kufuneka itshizwe ngokuphindaphindiweyo, echaphazela ukusebenza kakuhle kwemveliso;
2.4 Irabha egqunyiweyo ayinyamezeli kakuhle iaromatics kunye nezinye iintlobo zezinyibilikisi. Irabha enekloriji yokwaleka ayinakusetyenziswa njengokwaleka eludongeni lwangaphakathi kwindawo apho kunokubakho izinto ezinganyamezeliyo, ezifana nombhobho wekhemikhali, izixhobo zokuvelisa kunye namatanki okugcina. Ngelo xesha, i-rubber ye-rubber ye-chlorine ayinakuba yisiseko sexesha elide kunye namafutha ezilwanyana kunye namafutha emifuno;

isalathiso sophuhliso lwerabha eneklorini

1. Uphando malunga nokuguquguquka kwefilimu yepeyinti Iingubo zeerubha ezifakwe kwi-chlorated zisetyenziselwa unyango oluchasene ne-corrosion yeemveliso zetsimbi.

Ekubeni umthamo weemveliso zetsimbi uya kutshintsha kakhulu xa ubushushu buguquka, ukwenzela ukuba kuqinisekiswe ukuba umgangatho wefilimu yepeyinti awuchaphazeleki kakhulu xa i-substrate ikhula kunye nezivumelwano, i-rubber ye-rubber ye-chlorine kufuneka ibe nokuguquguquka okulungileyo ukunciphisa uxinzelelo oluveliswayo xa i-substrate yandiswa kakhulu. Okwangoku, indlela ephambili yokuphucula ukuguquguquka kwepeyinti yerabha eklorini kukongeza iparafini eneklorini. Ukususela kwidatha yovavanyo, xa inani elipheleleyo leparafini eklorini ifikelela kwi-20% ye-resin yerubha eklorini, ukuguquguquka kwefilimu kunokufikelela kwi-1 ~ 2mm.

2. Uphando kwiteknoloji yokuguqula
Ukuze kuphuculwe iipropati zefilimu yepeyinti kunye nokwandisa uluhlu lwezicelo zeerubha ezixutywe ngeklorini, abaphandi baye baqhuba izifundo ezininzi zokuguqulwa kwiingubo zerubha eziklorini. Ngokusebenzisa irabha eneklorini ene-alkyd, epoxy ester, epoxy, coal tar pitch, thermoplastic acrylic acid kunye nevinyl acetate copolymer resin, i-composite copolymer resin, i-composite i-copolymer resin, i-composite coposite yenze inkqubela phambili ecacileyo kwi-flexible yefilimu yepeyinti, ukuxhathisa imozulu kunye nokuxhathisa ukubola, kunye nokukhuthaza uphuhliso loshishino olunzima lokukhusela i-corrosion.

3. Funda ngomxholo oqinileyo weengubo
Umxholo oqinileyo wokugquma irabha eklorini iphantsi kwaye ubukhulu befilimu buncinci, ukwenzela ukuba ukuhlangabezana neemfuno zobunzima befilimu, kuyimfuneko ukwandisa inani lamaxesha okuxubha kunye nokuchaphazela ukusebenza kakuhle kwemveliso. Ukuze ucombulule le ngxaki, kuyimfuneko ukuqala ukusuka kwingcambu kunye nokuphucula umxholo oqinileyo wepeyinti. Ekubeni iingubo zerubha ezixutywe ngeklorini zinzima ukunkcenkceshela, umxholo oqinileyo unokuncitshiswa kuphela ukwenzela ukuqinisekisa ukusebenza kokwakhiwa. Okwangoku, umxholo oqinileyo weerubha zeklorini ziphakathi kwe-35% kunye ne-49%, kwaye umxholo we-solvent uphezulu, ochaphazela ukusebenza kokusingqongileyo kweengubo.

Iindlela eziphambili zokuphucula umxholo oqinileyo weerabha ezineklorini kukulungelelanisa ixesha lokungena kwegesi yeklorini kunye nokulawula ubushushu bokusabela xa uvelisa i-resin yerabha eklorini.
