Si loo yareeyo gubashada uu keeno dabka, dharka dab-demiska ayaa ah khadka ugu dambeeya ee difaaca si loo hubiyo badbaadada isticmaalaha, sidaas darteed sifooyinka ilaalinta ee dharka ololka ayaa aad muhiim u ah, gaar ahaan raaxada, ololka dabka iyo hoos u dhigista dabka. Kaliya saddexdan tilmaame ayaa buuxinaya shuruudaha halbeegyada qaranka isla mar ahaantaana, ayaa si fiican u ciyaari kara door ilaalin ah.Shidaalka Bamka Dabka ee la qaadi karo
Ka dib marka la taabto ololka iyo walxaha kulul, dab-dejiyayaal ku habboon ayaa naftooda ka ilaaliya inay shidaan, guban ama qiiqaan muddo cayiman.Shidaalka Bamka Dabka ee la qaadi karoka ilaalinta shaqaalaha holac furan ama ilo kulaylka. Sidaa darteed, waxqabadka suudhadhka dab-damiska ayaa aad muhiim u ah, gaar ahaan raaxada, dab-demiska iyo dab-demiska.Shidaalka Bamka Dabka ee la qaadi karoKaliya marka saddexdan tilmaame ay buuxiyaan shuruudaha isku mar, ayaa shaqada ilaalinta si fiican loo ciyaari karaa.
Waqtigan xaadirka ah, waxaa jira noocyo badan oo ah dharka dib u ololeeya ee loo isticmaalo suuqa, oo ay ku jiraan suufka ololka, polyester-ka ololka wax laga beddelay, taxanaha arylon (sida arylacrylic, acrylic), iwm, laakiin waxaa jira tiro yar oo tayo sare leh oo dab-damis ah oo leh raaxo leh, dabcinta ololka iyo dhimista dabka. Sababtoo ah fiber-ku ma qummana, dhammaantood waxay leeyihiin waxyaalahooda iyo meelaha ay ku fiican yihiin.
Maro ololaysa in kastoo raaxo leh, laakiin xoog yar, iska caabin heerkul hooseeya, 180 ℃ carbonization; fiber Aramid, fiber acrylic, interposition aramid fiber yaraynta dabka, nuugista qoyaanku waa mid yar, raaxo liidata; Paracaramid waxay leedahay iska caabin heerkul sarreeya, hoos u dhaca dabka, laakiin raaxada liidata; Fiilooyinka PBO (polyp-styrene iyo dioxazole) kuma lumiyaan dabka, laakiin hadda maaha kuwo deegaan ah oo waa qaali. Intaa waxaa dheer, sababtoo ah hygroscopicity fiber polymer waa yar yahay, xidhashada raaxada waa liidata.
Raaxada, ololka celiska iyo hoos u dhaca heerkulka sare ee dharka dib u ololeeya ayaa sidoo kale muhiim ah. Kaliya marka la isku daro saddexdan hawlood ee dharka dab-demiska waxay siin kartaa ilaalin wanaagsan qofka xiran. Si loo daboolo shuruudaha saddexdan sifo ee dharka ololka, shirkadaha hadda jira ee Shiinaha waxay soo saareen aramid isku dhafan oo isku dhafan oo ololka ololka ah oo leh fiber flame cellulose oo ah qalabka aasaasiga ah iyo fiber-aramid sida qalfoofka, iyada oo la tixgelinayo raaxada, ololka. dib u dhigista iyo kulaylka oo yaraada ee dharka dib u celisa ololka.
