Sealant waa shay daboolaya oo qaabeeya qaabka dusha wax lagu xidho, ma fududa in la dareero, oo leh xabag gaar ah. Waa xabag loo isticmaalo in lagu buuxiyo godadka u dhexeeya shayada si ay u ciyaaraan door xidhidh. Waxay leedahay hawlaha ka-hortagga daadinta, biyuhu, ka-hortagga gariirka, dahaarka dhawaaqa iyo kuleylka kulaylka.
Caadi ahaan waxay ku salaysan tahay walxaha viscous ee engegan ama aan qallajin sida asphalt, resin dabiiciga ah ama resin synthetic, caag dabiici ah ama caag synthetic ah. Waxaa lagu sameeyaa maaddooyin aan firfircooneyn sida talc, dhoobo, kaarboon madow, titanium dioxide iyo asbestos, ka dibna lagu daro balaastikada, dareerayaasha, wakiilada daweynta, dardar-geliyayaasha, iwm.
Kala soocida shaabadeynta
Sealant waxa loo qaybin karaa xidhid laastikada ah, gaasaska dareeraha ah ee dareeraha ah iyo saddex qaybood oo shaabadaysan.
Marka loo eego kala soocidda ka kooban kiimikada:waxa loo qaybin karaa nooca caag ah, nooca resin, nooca saliid ku salaysan iyo polymer sealant dabiiciga ah. Habkan kala-soocidda ayaa ogaan kara sifooyinka alaabta polymer-ka, waxay ka tarjumaysaa caabbinta heerkulka, xirida iyo la qabsiga warbaahinta kala duwan.
Nooca cinjirka:Noocaan daboolka ah wuxuu ku saleysan yahay caag. Caadooyinka caadiga ah ee la isticmaalo waa caag polysulfide, caag silikoon, caag poliurethane, caag neoprene iyo caag butyl ah.
Nooca xabagta:Noocaan shaabadeynta ah waxay ku saleysan tahay resin. Xabagta sida caadiga ah loo isticmaalo waa xabagta epoxy, xabagta polyester-ka aan saturated ahayn, xabagta phenolic, xabagta polyacrylic, resin polyvinyl chloride, iwm.
Saliid ku salaysan:Noocaan daboolka ah wuxuu ku saleysan yahay saliid. Saliidaha sida caadiga ah loo isticmaalo waa saliidaha kala duwan ee khudradda sida saliidda linseed, saliidda castor oil iyo tung oil, iyo saliidaha xoolaha sida saliidda kalluunka.
Kala soocida sida ku cad codsiga:waxaa loo qaybin karaa nooca heerkulka sare, nooca caabbinta qabow, nooca cadaadiska iyo wixii la mid ah.
Kala soocida iyadoo loo eegayo sifooyinka samaynta filimada:Waxa loo qaybin karaa nooc xabag qalalan, nooc qalalan oo diirran, nooc dhegdheg ah oo aan qallayl ahayn iyo nooca viscoelastic semi-qallalan.
Kala soocida isticmaalka:Waxa loo qaybin karaa xidhidhiyaha dhismaha, gawaadhida gawaadhida, xidhidhiyaha dahaarka, baakadaha baakadaha, macdanta macdanta iyo noocyo kale.
Marka loo eego waxqabadka dhismaha ka dib:waxa loo kala qaybin karaa laba nooc: daawaynta shaambadaynta iyo dawada-daawaynta. Waxaa ka mid ah, daawaynta shaandhaynta waxaa loo qaybin karaa mid adag oo dabacsan. Shaabad adag waa adag tahay ka dib vulcanization ama adkeysi, oo marar dhif ah ayaa leh barti, lama leexin karo, badanaana tolida lama dhaqaajin karo; shaabadeeyayaasha dabacsan waa kuwo dabacsan oo jilicsan vulkanization ka dib. Xirmooyinka aan daawaynta lahayn waa shaabad adag oo jilicsan oo wali sii ilaalinaysa tackifier aan qalajin ka dib dhismaha oo si joogto ah ugu guura xaaladda dusha sare.
