Indlela yokukhetha nokusebenzisa i-coating ekwaziyo ukumelana nomlilo kwizakhiwo zentsimbi

Kwizakhiwo zesakhiwo sentsimbi, ukuthintela umlilo kuyimfuneko. Nangona intsimbi ngokwayo ingatshi, amandla ayo ancipha ngokukhawuleza xa kushushu kakhulu, nto leyo ekhokelela ekuweni kwesakhiwo. Kufuneka kuthathwe amanyathelo okukhusela umlilo kwizakhiwo zentsimbi, kwaye ukusebenzisa ii-coating ezimelana nomlilo yenye yezona ndlela ziqhelekileyo nezibalulekileyo zokufezekisa oku. Namhlanje, siza kwazisa indlela yokukhetha nokusebenzisa ii-coating ezimelana nomlilo kwizakhiwo zentsimbi.

Iingubo ezimelana nomlilo zezakhiwo zentsimbi zahlulwe zibe ziintlobo ezingaphakathi kunye nezingezizo ezingaphakathi. Apha ngezantsi kukho intshayelelo emfutshane yomahluko wazo:

Ngoku sele sisazi ulwazi lwabo kunye nomahluko, mandikuxelele indlela yokukhetha i-coating efanelekileyo enokumelana nomlilo: Kwiindawo zangaphakathi ezineemfuno eziphezulu zobuhle, njengeevenkile ezinkulu, izakhiwo zeeofisi, iiholo zemiboniso, kunye neeholo zokulinda kwizikhululo zeenqwelo-moya, imiqadi yentsimbi kunye neekholamu ziyavezwa, kwaye azifuni nje kuphela umbono omhle kodwa kunye nokusebenza kakuhle kokulwa nomlilo, ukuba ixesha lokulwa nomlilo lingaphantsi kweeyure ezi-2 (okanye iiyure ezi-2.5), cebisa ukusebenzisa i-coating enokumelana nomlilo e-intumescent. Kwizakhiwo zentsimbi ekhanyayo kunye nezakhiwo zesakhelo sesithuba, cebisa nokusebenzisa i-coating enokumelana nomlilo e-intumescent, kuba ezi zakhiwo zinobuthathaka ekuthwaleni umthwalo, kwaye uhlobo olukhaphukhaphu lwe-coating e-intumescent luluncedo olukhulu.

Kwiikholamu zesakhiwo sentsimbi eziphakamileyo kunye nezinto ezithwala umthwalo, apho ukhuseleko lwesakhiwo lubaluleke ngakumbi kunempembelelo yokuhombisa, nakwiiprojekthi zemizi-mveliso ezinzima okanye ze-petrochemical ezifana nezityalo zoshishino kunye nezibonelelo ze-petrochemical ezineemfuno eziphezulu kakhulu zokukhusela umlilo, cebisa ukuba ukhethe iingubo ezingangenisi umlilo; kwiimfuno zexesha lokuthintela umlilo ≥3h; kwaye kwizakhiwo ezifihliweyo kunye nezakhiwo zentsimbi ezingagxininisi kakhulu kwiimpawu zokuhombisa, iingubo ezingangenisi umlilo kufuneka nazo zibekwe phambili.

Nangona ixabiso leengubo ezimelana nomlilo ezingaphakathi kwesisu libiza kakhulu, zifuna idosi encinci kwaye kulula ukuzisebenzisa. Ixabiso leengubo ezingezizo ezingaphakathi kwesisu liphantsi kakhulu, kodwa iingubo zazo zityebile, zifuna ubungakanani obukhulu kwindawo nganye, ngoko ke ixabiso lezinto azikho phantsi ngokuyimfuneko. (Ubukhulu bengubo obungezizo ezingaphakathi kwesisu akufuneki bube ngaphantsi kwe-15mm, kungenjalo, kunzima ukuqinisekisa umgangatho wokusetyenziswa kunye nesiphumo sokuthintela umlilo.)

Ngamafutshane, ngokuyintloko kukutshintshana phakathi “kobuhle kunye nokukhanya okukhaphukhaphu” kunye “nokuchasana nomlilo kunye nokuqina.” Ukuba le projekthi ingaphakathi kwaye ubuhle buyinto ephambili, ukugqunywa kwe-intumescent lukhetho lokuqala; nangona kunjalo, ukuba kubandakanya iindawo ezibalulekileyo ezithwala umthwalo wezakhiwo zoshishino ezinzima okanye izakhiwo zentsimbi eziphakamileyo, ukugqunywa kwe-non-intumescent, kunye nokuzinza kwazo kunye nokuchasana nomlilo okuphezulu, zisisiseko esithembekileyo ngakumbi.

Emva kokukhetha i-coating efanelekileyo enokuchasana nomlilo, ulwakhiwo oluchanekileyo lubalulekile ekufumaneni iziphumo ezilungileyo. Nazi ezinye iingcebiso zokwakha ezisebenzayo:

1) Unyango Lomphezulu: Qinisekisa ukuba umphezulu wentsimbi ucocekile, womile, kwaye awunayo i-rust okanye izinto ezingcolisayo. Ukusebenzisa umaleko we-anti-rust primer kunokuphucula ukunamathela kunye nokuphucula ukusebenza ngokubanzi. Oku kubalulekile ukuqinisekisa ukubopha okuqinileyo phakathi kwengubo ethintela umlilo kunye nesakhiwo sentsimbi kwaye akufuneki kushiywe.

2) Ubukhulu buphawu olubalulekileyo: Umgangatho wesizwe we-GB 14907-2018, "Iingubo eziKhusela uMlilo zeZakhiwo zeNsimbi", ucacisa ngokucacileyo ukuba ubukhulu bengubo yengubo echasene nomlilo engaphakathi kwe-tumescent akufuneki bube ngaphantsi kwe-1.5 mm, kwaye ubukhulu bengubo yengubo echasene nomlilo engaphakathi kwe-tumescent akufuneki bube ngaphantsi kwe-15 mm. Le yimfuneko esisiseko yokuqinisekisa umgangatho wokwakha kunye nesiphumo sokungatshisi. Kwangaxeshanye, kufuneka kulandelwe izikhokelo zomenzi malunga nobukhulu bengubo, ixesha lokomisa, kunye neemeko zokusingqongileyo. Oku kuya kuqinisekisa ukuba ingubo ifikelela ekusebenzeni kwayo okulindelweyo.

3) Ulondolozo oluqhelekileyo: Hlola rhoqo umphezulu wengubo ukuze ubone iimpawu zokuguguleka okanye zokonakala. Sombulula naziphi na iingxaki ngokukhawuleza ukuze ugcine izinga lokumelana nomlilo.

Xa usebenzisa ii-intumescent fire coats, kubalulekile ukuqinisekisa ukuba ziyahambelana kwaye ziyahambelana ne-anti-corrosion coating kunye ne-topcoat engaphantsi; kungenjalo, isiphumo se-intumescent sinokuphazamiseka, nto leyo enokubangela ukuba i-coating peel iqale. Ulandelelwano oluqhelekileyo lwesicelo lulandelayo: i-anti-corrosion primer → i-anti-corrosion intermediate coat → i-intumescent fire resistant coating → i-anti-corrosion topcoat.
