I-Cast Iron Pipe A1 Indlela Elungile Yesitoreji ye-Epoxy Paint

I-Cast iron pipe epoxy resin iyadingeka ukuze kufinyelelwe kumahora angama-350 okuhlolwa kwesifutho sikasawoti ngaphansi kwezinga le-EN877, ikakhulukazi.Ipayipi le-DS sml lingafinyelela amahora angu-1500 wesifutho sikasawotitest(ithole isitifiketi saseHong Kong CASTCO ngo-2025). Kunconyelwe ukusetshenziswa ezindaweni ezinomswakama nezinemvula, ikakhulukazi ngasogwini lolwandle, i-epoxy resin enamathela esivikweni sangaphandle sepayipi le-DS SML inikeza ukuvikeleka okuhle kwepayipi. Ngokusetshenziswa okwandayo kwamakhemikhali asendlini njengama-acids e-organic kanye ne-caustic soda, i-epoxy coating iwumgoqo ongcono kakhulu omelene nezinto eziphazamisayo, kuyilapho futhi idala amapayipi abushelelezi ukuvimbela ukuvala ukungcola. Izakhiwo zokunqanda ukugqwala kwamapayipi ensimbi awenza asetshenziswe kabanzi kumalabhorethri, izibhedlela, amafekthri kanye nezindawo zokuhlala emhlabeni jikelele.

Kodwa-ke, uma upende ungagcinwanga kahle, ungabangela ipayipi lensimbi ukuba libe lula noma lishintshe umbala ngemva kokupenda, kuthinte ikhwalithi yokubukeka nokusebenza kokuvikela komkhiqizo.

1. Indlela elungile yokugcina kapende we-epoxy we-A1

I-A1 epoxy paint iyisivikelo esisebenza kahle kakhulu, futhi izimo zayo zokugcina zithinta ngokuqondile ukuzinza kwe-coating kanye nomphumela wokumboza. Indlela yokulondoloza efanele ihlanganisa izici ezilandelayo:

1. Ukulawula izinga lokushisa

Izinga lokushisa elifanele: Upende we-epoxy we-A1 kufanele ugcinwe endaweni engu-5℃~30℃ ukuze kugwenywe izinga lokushisa eliphezulu noma eliphansi elithinta ukuzinza kwamakhemikhali kapende.

Gwema amazinga okushisa aphezulu:Izinga lokushisa eliphezulu (>35℃) lizobangela isincibiliki kupende ukuthi sihwamuke ngokushesha kakhulu, futhi ingxenye ye-resin ingase ibhekane ne-polymerization, okuzokhuphula i-viscosity kapende noma kubangele ukwehluleka ukuphulukisa.

Izinga lokushisa eliphansi (<0℃) lingase libangele izingxenye ezithile kupende ukuthi zicwebezele noma zihlukane, okubangele ukuncipha kokunamathela noma umbala ongalingani ngemva kokupenda.

2. Ukuphathwa komswakama

Indawo eyomile: Umswakama ohlobene nendawo yokugcina impahla kufanele ulawulwe phakathi kuka-50% no-70% ukuvimbela umoya omswakama ukuthi ungangeni ebhakedeni likapende.

Ivalwe futhi ivikele umswakama: Ibhakede likapende kufanele livalwe ngokuqinile ukuze kunqandwe umswakama ukungena, ngaphandle kwalokho lingabangela ukuhlukaniswa kopende, ukuhlanganisa noma ukuphulukiswa okungavamile.

3. Isitoreji kude nokukhanya

Gwema ukukhanya kwelanga okuqondile: Imisebe ye-Ultraviolet izosheshisa ukuguga kwe-epoxy resin, ibangele ukushintsha kombala kapende noma ukuwohloka kokusebenza. Ngakho-ke, upende kufanele ugcinwe endaweni epholile, engenakukhanya.

Sebenzisa iziqukathi ezimnyama: Abanye opende be-epoxy be-A1 bapakishwa ngemibala emnyama ukuze kuncishiswe ukuzwela kwesithombe. Iphakheji yokuqala kufanele igcinwe injalo ngesikhathi sokugcina.

4. Gwema ukuma isikhathi eside

Phenduka njalo: Uma upende ugcinwe isikhathi eside (ngaphezu kwezinyanga eziyisi-6), ibhakede likapende kufanele liguqulwe noma ligoqwe njalo ukuze kuvinjelwe i-pigment kanye ne-resin ukuthi ihlale futhi ihlukanise.

Isimiso sokuqala sokuqala: Sebenzisa ngokulandelana kwedethi yokukhiqiza ukuze ugweme ukuhluleka kopende ngenxa yokuphelelwa yisikhathi.

5. Gwema ukungcola kwamakhemikhali

Gcina ngokuhlukene: Upende kufanele ugcinwe kude namakhemikhali afana nama-asidi, ama-alkali, nezinyibilikisi eziphilayo ukuze kugwenywe ukusabela kwamakhemikhali okubangela ukuwohloka.

Ukungena komoya okuhle: Indawo yokugcina kufanele ifakwe umoya ukuze kuvinjelwe ukunqwabelana kwezinto eziguquguqukayo ezithinta ikhwalithi kapende.

Okulandelayo yizithombe zokupakishwa zepayipi le-SML nokufakwa endaweni yokugcina impahla ye-DINSEN:

2. Ukuhlaziywa kwezimbangela zokukhanya kombala wepayipi lensimbi noma ukushintsha kombala

Uma upende we-epoxy we-A1 ungagcinwanga kahle, ipayipi lensimbi elisansimbi ngemva kokupenda lingase libe nezinkinga ezinjengokukhanya, ukuphuzi, ukuba mhlophe, noma ukuguga kancane. Izizathu eziyinhloko zihlanganisa:

1. Ukushisa okuphezulu kubangela ukuguga kwe-resin

I-Phenomenon: Umbala wopende uphenduka ubephuzi noma ube mnyama ngemva kokudweba.

Imbangela: Ngaphansi kwezinga lokushisa eliphezulu, i-epoxy resin ingase ikhiphe i-oxidize noma ixhumane, ibangele ukuthi umbala kapende ushintshe. Ngemuva kokudweba, upende ongaphezulu kwepayipi lensimbi ungalahlekelwa umbala wawo wangempela ngenxa yokuguga kwe-resin.

2. Ukungena komswakama kuholela ekwelapheni okungavamile

I-Phenomenon: Inkungu emhlophe, umbala omhlophe noma ongalingani uvela ebusweni bengubo.

Imbangela: Umgqomo kapende awuvalwanga ngokuqinile ngesikhathi sokugcina. Emuva kokuthi umswakama usungenile, uhlangana ne-ejenti elaphayo ukukhiqiza usawoti we-amine noma i-carbon dioxide, okuholela ekulimaleni kwenkungu ebusweni bento enamathelayo, kuthinte ukucwebezela kwensimbi yepayipi lensimbi ekhonjiwe.

3. Ukuwohloka kwezithombe okubangelwa imisebe ye-ultraviolet

I-Phenomenon: Umbala wepende uba lula noma umehluko wombala wenzeka.

Imbangela: Imisebe ye-ultraviolet elangeni izobhubhisa i-pigment nesakhiwo se-resin kupende, ibangele umbala ongaphezulu wepayipi lensimbi elibunjiwe ngemva kokupenda ukuthi unyamalale kancane kancane noma ushintshe umbala.

4. Ukushintshashintsha kwe-solvent noma ukungcoliswa

I-Phenomenon: Izinhlayiya, izimbobo ezishwabene noma ukushintsha kombala kuvela efilimini kapende.

Imbangela: Ukushintshashintsha kwe-solvent okweqile kwenza i-viscosity kapende iphakame kakhulu, futhi i-atomization engemihle ngesikhathi sokufafaza iholela kumbala ongalingani.
Ukungcola (njengothuli namafutha) okuxutshwe phakathi ngesikhathi sokugcinwa kuzothinta izakhiwo zefilimu zopende futhi kubangele ukukhubazeka ebusweni bepayipi yensimbi ekhonjiwe.

3. Ungawugwema kanjani umbala ongavamile wepayipi lensimbi emva kokudweba

Landela ngokuqinile izimo zokugcina futhi uqinisekise izidingo zokushisa, umswakama, ukuvikela ukukhanya, njll.Ukugcinwa okungalungile kwepayipi lensimbi elinopende we-epoxy we-A1 kungase kubangele umbala ube lula, ube phuzi noma ushintshe umbala. Ngokulawula ngokuqinile izinga lokushisa, umswakama, ukuvikelwa kokukhanya nezinye izimo, nokuhlola njalo isimo se-pt, ukukhubazeka kokumboza okubangelwa izinkinga zokugcina kungagwenywa ngokuphumelelayo, ukuqinisekisa ukuthi ubuhle nokusebenza kokuvikela kwepayipi yensimbi ekhonjiwe kusesimweni esihle kakhulu.
