Kala duwanaanshaha Codsiga

HP-669 si guul leh ayaa loogu isticmaalaa warshadaha caagga ah sida wakiilka isku xirka poly sulfur silane ee laba-shaqo leh.
HP-669 waxaa loo isticmaali karaa nidaamka caagga ah ee la qalajiyey iyadoo la adeegsanayo buuxinta sida silica, fiberglass, budada talc, budada mica iyo dhoobada oo ah wakiilka xoojinta. Waxay hagaajin kartaa sifooyinka xoojinta ee buuxinta iyo sifooyinka iska caabbinta caagga.
Waa ku habboon tahay in loo isticmaalo sidii wax lagu daro caagga - wakiilka vulcanizing iyo firfircooni ku sameeya polymers-ka sida NR, IR, SBR, BR, NBR iyo EPDM.
Inta lagu jiro habka vulcanization, heerka isku xidhka ee alkyl poly-sulfur wuxuu la mid yahay heerka deoksaydhka ee sulfur, sidaa darteed waxay u dhaqantaa si ay uga hortagto deoksaydhka ee vulcanization, ka dibna waxay horumarisaa sifooyinka qallooca firfircoon sida ururinta kulaylka iyo dildilaaca ballaarinta. Afarta atamka sulfur waxay u dhaqmi karaan sidii firfircooni u kicinta vulcanization.
Xaaladaha firfircoon iyo kuwa aan degganayn, waxaa loo isticmaalaa soo saarista alaabadan caagga ah: taayirada, tuubada, duubka caagga ah, suunka, fiilada, kabaha iyo alaabada aasaaska farsamada. Waxay hagaajin kartaa iska caabbinta xoqidda, jarista iska caabbinta iyo iska caabbinta cadaadiska, yaraynta luminta hysteresis iyo hygroscopicity, hagaajinta sifooyinka farsamada iyo dhejiska, iyo kordhinta waxqabadka gabowga kulaylka, modulus iyo cimriga dabacsanaanta.
Ku dar walxaha isku xidhka sulfur-silane warshadaha taayirada caagga ah, kaliya ma aha inay hoos u dhigto khatarta daloolinta heerkulka aadka u sarreeya ee wadada xawaaraha sare ku socda ama waqti dheer, laakiin sidoo kale waxay yareysaa iska caabbinta duubista taayirada, ka dibna yaree isticmaalka shidaalka, tirada qiiqa ee CO2 si loo ilaaliyo deegaanka ee dhimista kaarboonka.
