Ipeyinti ifafazwe phezu kwesakhiwo sensimbi, ngokuqhelekileyo idlala indima yokuhlobisa.Kwimeko yomlilo, iyanwenwa kwaye ijiye kwaye i-carbonize yenze aumaleko wekhabhoni ongatshiyo wesiponji, ngaloo ndlela kuphuculwe umda wokumelana nomlilo wesakhiwo sensimbi ukuyangaphezu kweeyure ze-2.5, ukuphumelela ixesha lokucima umlilo kunye nokukhusela ngokufanelekileyo.Izakhiwo zentsimbi zikhuselwe emlilweni.
I-1, i-emulsion ye-silicone-acrylic kunye ne-chlorine emulsion edibeneyo exutywe, inokuphuculaukumelana namanzikwayeukumelana nomliloyesakhiwo sentsimbi yangaphakathi ebhityileyo yokwaleka umlilo, kodwa ukwenza uvavanyo lokuhambelana kakuhle ukuthintela ukwenzeka demulsification.
I-2, ukongezwa kwe-potassium silicate ye-inorganic potassium kunokuphucula ukuhambelana kwefilimu yokugqoka, ngaloo ndlela kuphuculwe ukuxhathisa kwamanzi kunye nokumelana nomlilo kwefilimu yokugubungela, kodwa kufuneka ixutywe kwangaphambili kunye nezinto ezisisiseko xa zongezwa, kwaye emva koko zongezwa ngokukhawuleza kwi-pre. -i-slurry ukukhusela i-polyphosphoric acid Ibhodi yenziwe ibe ngamasuntswana anqabileyo.
I-3, i-Hydroxypropyl methylcellulose kunye ne-bentonite inokubonelela ngokufanelekileyo ukugcinwa kwamanzi okufunekayo kunye nexabiso le-thixotropic lenkqubo, ukuphucula ukunyameka kokuqala kokuqhekeka, kunyekulula ukutshiza, ukwakhiwa kokugquma.
Sebenzisa kwisakhiwo sentsimbi yesakhiwo ngaphakathi kweeyure ze-2.5 zomda wokumelana nomlilo, njengayeimiqadi, ii-slabs, amalungu athwele uphahla kuhlobo lwesakhiwo;iikholamu, imiqadi, amacwecwe kunyeiintlobo ezahlukeneyo zentsimbi zokukhanyakunye neegridi kudidi lwesibini lwezakhiwo.

Indawo yokwakha:
Ngaphambi kwenkqubo yokwakha kunye nokumisa ukomisa kunye nokunyanga, ubushushu be-ambient kufuneka bugcinwe kwi-5-40 ° C, umswakama ohambelanayo> 90%, umoya wendawo kufuneka ube kuhle.
Inokuthi isetyenziswe ngokutshiza, ukuxubha, i-roller coating, njl njl. Emva kokuba i-coating ifakwe kwisicelo sangaphambili isomisiwe ngokusisiseko kwaye iqiniswe, iphinda ifakwe kwakhona, ngokuqhelekileyo ngamaxesha angama-8-24, kude kube yi-thickness oyifunayo.
1. Ukwakhiwa kwengubo yomlilo, ngenxa yokuba i-fireproof coating idla ngokukrakra, kuyacetyiswa ukuba usebenzise isibhamu sokuzilinganisa ngokuzimeleyo kunye nokulawulwa koxinzelelo oluzenzekelayo lwe-0.4-0.6Mpa;ukulungiswa kwenxalenye kunye nokwakhiwa kwendawo encinci, inokuxutywa, itshizwe okanye iqengqwe, isebenzisa enye okanye Iindlela ezininzi zilungele ukwakha.Umbhobho wokutshiza weprimer yokutshiza ungasetyenziselwa ukugquma isitshizi xa i-diameter ehlengahlengiswayo iyi-1-3mm.Ukuba ipeyintwe ngesandla, inani lokupasa kwebrashi kufuneka linyuswe.
2. Ubukhulu bepasi nganye abuyi kuba ngaphezulu kwe-0.5mm xa kutshizwa, kwaye kuya kutshizwa kube kanye kwiiyure ezisi-8 kwimozulu entle.Xa utshiza idyasi enye yepeyinti, kufuneka yomiswe phambi kokuba kufakwe isitshizi.Ubuninzi bomgca ngamnye wokutshiza ngesandla buncinci, kwaye inani leengoma lilinganiswa ngokobunzima.
3. Ngokweemfuno zexesha elichasayo lesakhiwo sensimbi edibeneyo, ubuninzi obuhambelanayo bokugquma bunqunywe.Ukusetyenziswa kokusetyenziswa kweengqungquthela kwi-square meter nganye kwi-square meter ye-coating yi-1-1.5kg.
4. Emva kokutshiza i-coat retardant yomlilo, kucetyiswa ukuba usebenzise amaxesha angama-1-2 e-acrylic okanye i-polyurethane anticorrosive topcoat ukuqinisekisa ukuba ifilimu yepeyinti igudileyo kwaye igudileyo kwaye inefuthe elihle lokuhlobisa.
Yonke imiphezulu kufuneka icoceke, yome kwaye ingangcoliseki.Ngaphambi kokupeyinta, kufuneka kuhlolwe kwaye kuphathwe ngokuhambelana nomgangatho we-ISO8504: 2000.
Iqondo lobushushu elisisiseko alikho ngaphantsi kwe-0℃, kwaye ubuncinane ngaphezu kweqondo lombethe lomoya yi-3℃, ukufuma okunxulumene ne-85% (iqondo lobushushu kunye nokufuma okuhambelanayo kufuneka kulinganiswe kufutshane nesiseko sezinto), inkungu, imvula, ikhephu, umoya nemvula. ulwakhiwo lwalelwe ngokungqongqo.
I-Alkyd primer okanye i-epoxy zinc rich primer, i-epoxy primer, kunye ne-topcoat iya kuba yi-alkyd topcoat, i-enamel, i-acrylic topcoat, i-enamel ye-acrylic njalo njalo.
