1. Ukumelana nokuhlolwa kwesisindo esiphakathi
Umkhiqizo osuqediwe ungahlehliswa, ofakwe ku-media eyodwa noma eminingana ekhethiwe, enesisindo ngemuva kokushisa okuthile nesikhathi, futhi uhlobo lwezinto ezibonakalayo lungafakwa ngokuya ngesilinganiso sokushintsha kwesisindo kanye nesilinganiso sokushintsha kobulukhuni.
Isibonelo, egxiliswa emafutheni ayi-100 ama-oyela amahora angama-24, i-NBR, irabha ye-fluorine, i-eco, i-CR inoshintsho oluncane ngekhwalithi nobulukhuni, futhi ukunwebeka kwevolumu kusobala.
2. I-Hot Air Age Test
Thatha amasampula emikhiqizweni eseqediwe, uwafake ebhokisini lokuguga ngolunye usuku, bese ubheka into ngemuva kokuguga. Ukuguga kancane kancane kungakhuphuka kancane kancane. Isibonelo, cr, NR, ne-SBR kuzoba brittle ngamadigri ayi-150, kuyilapho i-NBR EPDM isekhona. Lapho amazinga okushisa ekhuphuka abe ngama-degree angama-180, i-NBR ejwayelekile izoba brittle; Futhi i-HNBR izophinde ibe brittle ngama-degree angama-230, futhi irabha le-fluorine kanye ne-silicone kusanobunzima obuhle.
3. Indlela yokuhlanganisa
Thatha isampula elincane bese ulishisa emoyeni. Bheka into.
Ngokuvamile, irabha ye-fluorine, cr, csm akhululekile emlilweni, futhi noma ngabe ilangabi livutha, lincane kakhulu kune-General NR ne-ERDM. Vele, uma sibhekisisa kakhulu, isimo sokuvutha, umbala, kanye nephunga futhi sisinikeza imininingwane eminingi. Isibonelo, lapho i-NBR / PVC ihlanganiswa ne-glue, lapho kunomthombo womlilo, izikhala zomlilo futhi zibonakala zinjengamanzi. Kumele kuqashelwe ukuthi kwesinye isikhathi i-flame retardant kodwa i-halogen-free glue izozichaza nomlilo, okufanele aphinde athathwe ngenye indlela.
4. Ukulinganisa amandla adonsela phansi athile
Sebenzisa isikali se-elekthronikhi noma ibhalansi yokuhlaziya, enembile ku-0.01 gram, kanye nengilazi yamanzi nezinwele.
Ngokuvamile, irabha ye-fluorine inamandla adonsela phansi amakhulu kunawo wonke, ngaphezulu kwe-1.8, futhi iningi lemikhiqizo ye-CR ECO inengxenye enkulu engenhla kwe-1.3. Lezi glues zingabhekwa.
5. Indlela yokushisa ephansi
Thatha isampula kusuka kumkhiqizo osuqediwe bese usebenzisa iqhwa elomile notshwala ukuze wakhe indawo efanelekile ye-cryogenic. Cwilisa isampula endaweni yokushisa ephansi imizuzu engu-2-5, uzizwe ukuthamba nobulukhuni emazingeni okushisa akhethiwe. Isibonelo, ama-degrees at -40, izinga lokushisa elifanayo eliphakeme kanye nokumelana namafutha e-silica gel kanye nerabha ye-fluorine kuqhathaniswa, futhi i-silica gel iyathambile.
