Mutengo wakanaka Accelerator DPTU / CA cas 102-08-9 N,N-Diphenylthiourea
Upfu chena. Density ndeye 1.32. Kuvava zvishoma, kupisa, kunenge kusina chepfu. Soluble mudoro, diethyl ether, acetone, cyclohexanone, tetrohydrofuran, chikamu chinonyungudika muPVC plasticizers, isinganyunguriki mumvura uye CS2. Soluble in alkali solutions uye kunaya kubva muacid solution.
Medium-speed vulcanization accelerator. Kupisa kwayo kwakanyanya i80 ° C, inofanira kudzivirirwa kubva pakutanga sulfurization kana yakasanganiswa. Iyo activation yakakwira kana tembiricha iri kupfuura 100C.
Inoshandiswa muzvigadzirwa zve latex, tambo uye zvakajairika zvigadzirwa zvemaindasitiri. Zvigadzirwa zvayo zvakapedzwa zvine mukana wekuoma, kusimba uye kusimba. asi inogona kushandura ruvara pamhedzisiro yechiedza.
Inonyanya kushandiswa kune zvakasikwa rabha, neoprene latex zvigadzirwa uye yakasikwa rabha latex, inogona zvakare kushandiswa kugadzira matai kugadzirisa glue, waya uye tambo, zvigadzirwa zvemaindasitiri, nezvimwe.
Yakarongedzwa mumambure 25kg yakarongedza. Yakachengetwa munzvimbo inotonhorera, yakaoma uye ine mhepo yakanaka. Nguva yekuchengetedza ndeye 2 gore.
