Product Description

Iri mvura pane tembiricha yekamuri, saka iri nyore kushandisa nekugadzirisa. Iyo tembiricha yegirazi yekuchinja ndeye -80 ℃ (-112 ℉) ine yakanakisa yakaderera tembiricha zvivakwa. Iwo ma mechanika ezvigadzirwa zvayo elastomer ari padyo nePTMG.

Iyo ine yakanakisa yakaderera-tembiricha michina zvivakwa uye yakafara tembiricha yekushandiswa.

Nekuda kweiyo yakanaka mamorekuru kuchinjika, inogona kutsiva PTMG mune inochinjika yematehwe echigadzirwa neingi. Inogona zvakare kushandiswa kune yakaderera-inodzivirira inonamira, machira, polyurethane elastomers, nezvimwe.

Kurongedza & Kuchengeta

Yakarongedzwa mu50kg / drum, 170kg / drum, Nguva yekuchengetedza ndeye 1 gore.

Mirayiridzo yekuchengetedza:

Kuchengetera kunofanirwa kunge kuchitonhorera, kuoma uye kufefetera. Mamiriro akanaka ari pakati -20 ~ 38 ℃. Sherufu yemwedzi gumi nemiviri, kana yapera, ichiri kushandiswa kana yasvika pachiyero kuburikidza nekuongororazve. Apo kutakurwa kunofanira kudzivisa mvura, chiedza chezuva. Usasanganise neoxidizer yakasimba.
