A rubber plasticizer is a reagent. The plasticization of rubber refers to the addition of certain substances in the rubber, which can reduce the force between the rubber molecules, thereby reducing the glass transition temperature of the rubber, making the rubber plasticity, fluidity, and facilitating the forming operations such as calendering and pressing. It can improve certain physical and mechanical properties of vulcanizates, such as lowering hardness and modulus, giving higher elasticity and nababbaba a panagpataud ti pudot, ken panangpasayaat ti resistensia ti lamiis..
The plasticization of rubber refers to the addition of certain substances in the rubber, which can reduce the force between the rubber molecules, thereby reducing the glass transition temperature of the rubber, making the rubber plasticity, fluidity, and facilitating the forming operations such as calendering and pressing. It can improve certain physical and mechanical properties of vulcanizates, such as lowering hardness and modulus, giving higher elasticity and lower heat generation, and improving cold resistance.
Plasticization of rubber can be done by physical and chemical methods. Chemical plasticization, including plasticizing and plasticizing in various plastics, is a process in rubber processing. In the case of synthetic rubber, the plasticization is introduced into the rubber molecular chain by chemical reaction to increase the flexibility of the molecular structure to achieve plasticization. . Chemical plasticization does not lose its effect due to the volatilization or precipitation of the plasticizing material, and the plasticizing effect is long-lasting and Isu a nakaawat ti ad-adu ken ad-adu nga atension. Ti pisikal a plastikisasion ket mangibagbaga ti panggep ti panagplastiko babaen dagiti kanayonan a substansia. Ti makunkuna a plastikisasion ket mangibagbaga ti pisikal a plastikisasion, ken ti nainayon a substansia iti pisikal a plastikisasion ket maawagan iti mangpalukneng a plasticizer..
Dagiti goma a pangpalukneng a plasticizers ket sapasap a naidasig kadagiti softener ken plasticizer segun ti polaridad ken panagusar da. daytoy ket nagtaud manipud kadagiti natural a substansia ken maawagan iti softener para iti saan a polar a goma. daytoy ket kangrunaan a maus-usar a kas maysa a plasticizer para iti polar a goma wenno plastik. nga agdama a naamammuan iti industria a kas dagiti plasticizers{4}} .
Ti plasticizer ket rumbeng a makasangpet kadagiti sumaganad a kasasaad bayat ti panagpataud ken panagusar: nasayaat a plasticizing effect, nababa a dosis, napartak a panagsebseb, nasayaat a panagtunos iti goma, nababa a volatility, awan ti panagakar, nasayaat a lamiis a resistensia, resistensia iti danum, resistensia iti lana ken resistensia. solvent, nasayaat a panagandur iti pudot, resistensia ti lawag, nasayaat nga elektrikal nga insulasion, nasayaat a panagandur iti gil-ayab, resistensia ti bakteria, awan kolorna, saan a makasabidong, nalaka ken nasayaat a {22}
Nupay kasta, daytoy ket gangani nga imposible a maaddaan ti maysa a plasticizer a naan-anay a mangpennek kadagiti kondision iti ngato. Gapuna, iti aktual a panagusar, dua wenno ad-adu pay a plasticizer ket maus-usar a kombinasion tapno mangbayad ti tunggal maysa iti tunggal maysa. ti kaadu ti plasticizer ket sapasap a naibagbaga a kas ti kangrunaan a plasticizer, ken ti sabali ket maawagan iti auxiliary plasticizer. .
Ti tipo ti plasticizer ket mabalin pay a mailasin iti petroleum plasticizer, coal tar plasticizer, pine oil plasticizer, fat plasticizer ken synthetic plasticizer segun iti gubuayan..
