Kev siv
Cov tshuab hluav taws xob siab, hluav taws kub tsis kam thiab tshuaj lom corrosion tsis kam ntawm phenol-formaldehde resin ua nws ib tug multifunctional cov khoom siv:
Hluav Taws Xob Hluav Taws Xob thiab hluav taws xob: siv los tsim cov kav insulating xws li cov board, hloov pauv, thiab lwm yam kub), thiab rwb thaiv tsev zoo dua li zoo tib yam li qub.
Kev Tsim Kho thiab Kho kom zoo nkauj: Phenolic ua npuas ncauj yog siv los ua cov khoom siv rwb thaiv tsev uas muaj hlawv thiab ua pa tawm me me, thiab ua tau los ua pa taws me me, thiab ua tau raws li cov neeg haus luam yeeb me me, thiab ua tau raws li cov neeg haus luam yeeb me me, thiab ua tau los ua pa taws me me, thiab ua tau raws li cov neeg haus luam yeeb me me, thiab ua tau los pa rau EU cov qauv kev tiv thaiv hluav taws.
Composite: impregnated iav fiber ntau lossis asbestos los ua laminates, siv rau cov tshuaj pipeline linings thiab corrosion-resistant khoom.
Casting thiab cov khoom siv refractory: raws li xuab zeb pwm binder, nws muab kev sib tsoo hauv cov hlau casting; Siv rau hauv kev tsim cov khoom lag luam magnesium magbon los txhim kho kom muaj zog kub-kub.
Cov Ntaub Ntawv Kev Nyab Xeeb
Tom qab kho, lub cob yog siv tshuaj tsis ruaj khov, tab sis kev ua kom muaj zog yuav tsim cov roj ntsha xws li hydrogen chloride thiab carbon monoxide, uas yuav tsum tau kho hauv tus neeg tshwj xeeb. EU ncav cuag cov kev cai txwv kev siv cov tshuaj ntsuab phthaltates (xws li DEHP).
