Butyl mpira kuzuia kwa viini 20mm crimp

Maelezo:
Kuna tofauti nyingi kati ya butyl na mpira wa asili. Faida kuu ni kwamba mpira wa butyl una utulivu bora wa kemikali na upinzani wa kuzeeka kuliko mpira wa asili. Inayo elasticity ya mpira wa asili na haina viungo vya protini, lakini haina butyl. Uingiliano wa kemikali na upinzani wa kuzeeka

Bidhaa ya mpira wa butyl ni laini-nyeupe-kama-nyeupe-kama-wiani na wiani wa 0.92g \ / cm3. Haina harufu, haina maji, na mumunyifu katika hexane na chloroform. Bidhaa pia ina upenyezaji wa hewa ya chini, hewa nzuri, na upinzani mzuri. Upinzani wa ozoni, upinzani wa kemikali, insulation ya umeme, upinzani wa kubadilika, upinzani wa kuzeeka, kunyonya kwa nishati na sifa zingine.

Sehemu kuu ya mpira wa butyl ni polyisobutylene. However, the methyl group in polyisobutylene has large steric obstacles, so the thermal motion of the molecules is not active, so its gas permeability is smaller than that of synthetic rubber, and the molecules are double The number of bonds in the main chain is very small, so it has very good resistance to ultraviolet rays, ozone and weather resistance, and also high heat resistance.

Faida za Stopper ya Mpira wa Butyl:

(1) Inayo hewa nzuri na upenyezaji mdogo wa hewa.

(2) Upinzani mzuri sana wa joto.

(3) Upinzani mzuri wa ozoni na upinzani wa hali ya hewa.

(4) Alkali na vimumunyisho vya kati vya asidi.

(5) Kunyonya kwa maji duni na upinzani mzuri wa mionzi
