daahan dab-demiska
Ereyada la midka ah ee Ingiriisiga
daahan dab-demiska
hantida kiimikada
Mabda'a ka hortagga dabka:
(1) Daahan dab-demiska laftiisa lama gubi karo, si substrate-ka la ilaaliyo uusan si toos ah ula xiriirin oksijiinta hawada;
Dahaarka dab-demiska ayaa leh heerkulka kuleylka hooseeya, dib u dhigista heerka heerkulka sare ee substrate-ka;
(3) Daahan dab-damis ah ayaa la kululeeyaa si uu u dumiyo gaasta aan guban karin, milo gaaska guban kara ee shayga la ilaaliyo waa la kululeeyaa si uu u burburo, si aanay u fududayn in la gubo ama hoos u dhigo heerka gubashada.
(4) Daahanka dab-demiska ee nitrogenous-ka ah ayaa lagu qurxiyaa kulayl, sida NO, kooxaha NH3, iyo kooxda xorta ah ee organic, waxay joojiyaan falcelinta silsiladda, yareeyaan heerkulka.
(5) Nooca balaadhinta dahaarka dab-demiska waa kululaynta xumbo balaadhinta, samaynta lakabka daboolka xumbo kaarboon waa la xidhay si loo ilaaliyo shayga, dib u dhigo wareejinta kulaylka iyo walxaha saldhigga ah, ka hortagga shayga gubanaya ama sababtoo ah kororka heerkulka uu sababay hoos u dhaca xoog leh.
Soo bandhigida alaabta iyo sifooyinka
Dahaarka dab-demiska waa iyada oo loo marayo burushka daahan ee dusha sare ee alaabta, waxay hagaajin kartaa caabbinta dabka ee alaabta, hoos u dhigi karta xawaaraha faafidda ololka, ama wakhti go'an waxay ka hortagi kartaa gubasho, nooca noocan ah waxaa loo yaqaannaa daahan dab-demiska. , ama loo yaqaan daahan ololka retardant.
Daahan dab-demiska ah ayaa loo isticmaalaa dusha sare ee substrate guban kara, kaas oo yarayn kara ololka dusha sare ee walxaha dahaarka leh, xannibaya faafitaanka degdegga ah ee dabka, oo wanaajiya xadka caabbinta dabka ee walxaha dahaarka leh.Codsaday dusha sare ee guban kara, si loo beddelo sifooyinka gubashada dusha walxaha, xannibo fiditaanka degdegga ah ee dabka;Ama lagu dabaqo qaybaha dhismaha, si loo hagaajiyo caabbinta dabka ee xubnaha dahaarka gaarka ah, oo loo yaqaan daahan dab-demiska.
isticmaal
A. Daahan aan fidin oo dab-celis ah ayaa inta badan loo isticmaalaa ka-hortagga dabka ee alwaax, saqafka fibreed iyo agabka kale ee looxa, iyo saqafka saqafka, saqafka, albaabada iyo daaqadaha qaab dhismeedka alwaax.
B. Daahan la fidin karo ayaa leh daahan balaadhinta aan sunta ahayn, daahan fidinta emulsion-ka, daahan balaadhinta ku salaysan dareeraha.
C. Daahan aan sun ahayn oo dab-damis ah ayaa loo isticmaali karaa dahaar aan dab-damis lahayn ama suuf aan dab-damis lahayn si loo ilaaliyo fiilooyinka, tuubooyinka polyetylenka iyo looxyada dahaarka.
D. daahan balaadhinta emulsion iyo daahan balaadhinta dabka ku salaysan ee dareeraha ah waxa loo isticmaali karaa dhismo, koronto, dabka xadhiga.
E. daahan cusub oo dab-demiska ah waa: daahan dab-damis ah oo hufan, daahan ilaalinta dabka biyaha milmaya, daahan dabka retardant daahan phenolic balaadhinta, poly vinyl acetate emulsion daahan cinjirka, heerkulka qolka qalalan tan iyo nooca biyaha ee milmi dabka intumescent daahan, polyolefin dab u adkaysta. dahaarka dahaarka, daahan dab-damis ah oo la beddelay oo koloriin sare daahan polyetylen, balaadhinta caag koloriin, firewalls, daahan daahan dab-damis, daahan dab xumbo, daahan silig iyo cable Daahan olol, daahan cusub refractory, shubida refractory daahan iyo wixii la mid ah.
xirmo iyo gaadiid
B. Alaabtan waxa loo isticmaali karaa,25KG, foosto.
C. Ku kaydi meel qabow, qalalan oo hawo leh oo gudaha ah.Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor intaan la isticmaalin.
D. Alaabtan waa in si fiican loo xiraa inta lagu jiro gaadiidka si looga hortago qoyaanka, alkali xooggan iyo aashitada, roobka iyo wasakhda kale ee isku darka.
