Silica dib-u-dhigista, waxaa loola jeedaa siligga xaaladaha dabka ee dabka, guud ahaan haddii la gubo silica, haddii siligga korantada la gooyo, dabka lagu xakamayn doono, oo aan ku faafin doonin, ololka dib-u-dhigista iyo xakameynta ololaha qiiqa qiiqa. Silica dib-u-dhigga oo ah qayb muhiim ah oo ka mid ah nabdoonaanta korantada, doorashada sheygooda waa muhiim, suuqa hadda jira ee loo isticmaalo qalabka dib-u-eegaTuubbo cunto, Xlpe, caalitone caag iyo qalab macdanta macdanta.
Flame dib-u-dhigista silig iyo xulashada qarashka fiilada
Tilmaamaha sare ee oksijiinta ee sheyga loo isticmaalo fiilada ololka ololka, waxa ugu fiican waxqabadka ololka ololka, laakiin kororka tusmada oksijiinta ah, waxaa lagama maarmaan ah in la lumo qaar ka mid ah guryaha kale. Haddii dhismayaasha jireed iyo habka loo yareeyo qalliinka, qalliinka waa adag yahay, oo qiimaha sheyga ayaa lagu gudbin karaa shuruudaha oksijiinka ee heerka caadiga ah, sheygu wuxuu ka soo bixi karaa shuruudaha fasalka B iyo fasalka A. Silicadii dib udhaca iyo agabyada fiilada ayaa inta badan loo qaybiyaa qalab aan caadi ahayn oo ololaya oo olol ah oo ololaya
1. Qalabka dib loo eegay ololka
Sababo la xiriira jahwareerka iyo siidaynta hydrogen Watation marka gubashada la kululeeyo, hydrogen Jasiirku wuxuu qabanayaa xididka firfircoon, si marka loo eego in lagu gaaro ujeedada aaladda dib loo soo celiyo dib-u-dhiska dib-u-dhaca. Caadi ahaan loo adeegsado waa polyvinyl chloride, neoprene caag, pollorosulfonated polyetylonlen, polyenene-propylene ruqruarta iyo agabyada kale.
(1) olole dib u dhac ku ah polyvinyl chloride chloride In order to improve the flame retardancy of PVC, halogen flame retardants (decabromodiphenyl ethers), chlorinated paraffins and synergic flame retardants are often added to the formula to improve the flame retardancy of PVC.
Ethylene Propylement Caag (EPDM): Hardo-ka-salka (guryaha korantada ee wanaagsan, iska caabbinta sare, waa inaan yareynaa cromplen cromplens-ka, si loo hagaajiyo astaamaha moluculal-ka oo ay sababaan astaamaha dib-u-dhigga ee sheyga;
(2) qiiq hooseeya iyo waxyaabo yar oo ololaya
Badiyaa loogu talagalay polyvinyl chloride chloride iyo chlorosultene-ka ah ee 'polyetyfonene' Ku dar Caco3 iyo (IOH) 3 illaa qaababka PVC. Zinc Bolbate iyo MOO3 waxay yareyn karaan xaddiga siidaynta HCL iyo qiiqa ee ololka polyvinyl chloride chloride chloride, oo yareynaya hawada, qiiqa qiiqa, laakiin waxay ka dhigi kartaa tusaha oksijiinta, laakiin waxay yareyn kartaa tusaha oksijiinta.
2. Qalabka dib-u-dhigga ee aan tooska ahayn
Polyoleffins waa walxaha aan lahayn halogen-ka, oo ka kooban hydrocarbons kuwaas oo jebiya kaarboon dioxide iyo biyo markii la gubay iyada oo aan la soo saarin qiiqa weyn iyo gaasaska waxyeellada leh. Sitronolenka badanaa waxaa ku jira polyetyylen (PE) iyo ethylne - vinyl acetate polymers (E-VA). Qalabkaani laftooda ma leh olole dib u dhac ah, waxay u baahan yihiin inay ku daraan dib-u-dhac ololaya oo olol ah iyo dib-u-dhac toos ah oo fosfooras ah, si ay uga baaraandegaan agabyada dib-u-eegista halogen-ka ah ee halogen-ka ah; Si kastaba ha noqotee, sababtoo ah la'aanta kooxaha Polar oo ku saabsan silsiladda molikalalbalar ee walxaha aan loo yaqaan 'polars' oo leh hydrophobicity, wejiga oo leh dib-u-dhacyada ololka ololka ee inorganic waa mid liidata, adag in si adag loo xiro. Si loo wanaajiyo waxqabadka dusha sare ee politmada, surplalatyaasha ayaa lagu dari karaa qaaciddada. Ama si cilmiga loo yaqaan 'polarmis' Waxaa lagu arki karaa in qaladka dib-u-dhigga ee ololka iyo fiilada ay wali faa'iido u leeyihiin, isticmaalkuna waa mid aad u fiican deegaanka.
