garaaca Polymer-ka: Dahaarka Sare ee PA12 iyo Mustaqbalka Sare - Iska caabinta Daalka Wareegga
Jirdhiska casriga ah iyo kuwa sare - warshadaha farsamada saxda ah, xadhigga siliga hadda looma arko qayb taagan; waa matoor kinetic ah oo firfircoon. Meesha fashilka ugu daran ee fiilooyinka caadiga ah ee PVC{2}ku dahaaran maaha birta lafteeda, laakiin waa "daalka polymeric" ee u horseeda micro{3} dildilaaca dusha sare. Marka dahaarka la jebiyo, qoyaanka soo gala waxa uu dedejiyaa daxalka gudaha 5x ka dhaqso badan birta soo shaac baxday.
Faa'iidada PA12 (Nylon 12)
Marka la eego heerka molecular, Nylon 12 waxa uu bixiyaa qaab-dhismeed semi{1}}crystalline gaar ah kaas oo ilaalinaya dabacsanaan mug leh xataa kumanaan wareegyo cadaadis ah Inkasta oo PVC-ga caadiga ah ay u egtahay inay noqoto mid jajaban maadaama balaastiijiyeyaasha ay soo baxayaan waqti ka dib, PA12 ayaa weli ah mid adkeysi leh. Tani waa sababta sare -qalabka jimicsiga dhamaadka iyo nidaamyada otomaatiga ah ee saxda ah ay ugu wareegayaan Nylon 12.
500,000-Cycle Benchmark:
Tijaabada warshadaha, fiilo caadi ahaan waxa lagu dul ordaa xidhmo dhexroor gaar ah leh (D: ratio D). Xadhkaha ganacsiga caadiga ahi waxay inta badan ku fashilmaan 120,000 ilaa 150,000 wareeg. Heerka farsamada SOLITE waxa uu amrayaa badbaadada ugu yar ee 500,000 wareeg ah. Tani ma aha tiro kaliya; waxay ka dhigan tahay 300% korodhka daaqada hawlgalka mishiinka. Iyada oo hoos u dhigaysa isku-dhafka is jiid-jiidka, PA12 waxay sidoo kale yaraynaysaa soo saarista kulaylka, iyada oo ilaalinaysa daacadnimada saliidaha cadaadiska sare ee gudaha{12}. Maareeyayaasha maraakiibta caalamiga ah, caqliga injineernimada waa mid fudud: polymer-ka saxda ah waa ilaaliyaha ugu dambeeya ee nafta birta.
