1. Ukumelana novavanyo lokuzuza ubunzima obuphakathi
Imveliso egqityiweyo ingenziwa isampuli, ifakwe kwimidiya enye okanye ezininzi ezikhethiweyo, zilinganiswe emva kobushushu obuthile kunye nexesha, kwaye uhlobo lwezinto eziphathekayo lunokuchazwa ngokwezinga lokutshintsha ubunzima kunye nesantya sokutshintsha ubunzima.
Ngokomzekelo, ukucwiliswa kwi-oyile ye-100 yeeyure ze-24, i-NBR, i-rubber ye-fluorine, i-ECO, i-CR inotshintsho oluncinci kumgangatho kunye nobunzima, ngelixa i-NR, i-EPDM, i-SBR ngaphezu kokuphindwe kabini ubunzima kunye nokutshintsha kobunzima kakhulu, kunye nokwandiswa kwevolumu. icacile.
2. Uvavanyo lokuguga lomoya oshushu
Thatha iisampulu kwiimveliso ezigqityiweyo, uzibeke kwibhokisi yokuguga yosuku olunye, kwaye ujonge le nto emva kokuguga.Ukuguga ngokuthe ngcembe kunokwandiswa ngokuthe ngcembe.Ngokomzekelo, i-CR, i-NR, kunye ne-SBR iya kuba yi-brittle kwii-degrees ze-150, ngelixa i-NBR EPDM ise-elastic.Xa izinga lokushisa liphakama ukuya kuma-degrees angama-180, i-NBR eqhelekileyo iya kuba yi-brittle;kunye ne-HNBR iya kuba brittle kwii-degrees ezingama-230, kwaye irabha ye-fluorine kunye ne-silicone iseno-elasticity elungileyo.
3. Indlela yokutshisa
Thatha isampuli encinci kwaye uyitshise emoyeni.jonga isenzeko.
Ngokuqhelekileyo, i-rubber ye-fluorine, i-CR, i-CSM ikhululekile emlilweni, kwaye nokuba ilangatye livutha, lincinci kakhulu kune-NR kunye ne-EPDM jikelele.Kakade ke, ukuba siqwalasela ngenyameko, imeko yokutsha, umbala, kunye nevumba nazo zisinika ulwazi oluninzi.Ngokomzekelo, xa i-NBR / PVC idibaniswe neglue, xa kukho umthombo womlilo, umlilo uqhuma kwaye ubonakala ngathi ufana namanzi.Kufuneka kuqatshelwe ukuba ngamanye amaxesha i-flame retardant kodwa i-halogen-free glue iya kuzicima ngokwayo emlilweni, okufuneka igqitywe ngakumbi ngezinye iindlela.
4. Ukulinganisa ubunzima obuthile
Sebenzisa isikali sombane okanye ibhalansi yokuhlalutya, echanekileyo ukuya kwi-0.01 gram, kunye neglasi yamanzi kunye neenwele.
Ngokuqhelekileyo, irabha ye-fluorine inobunzima obuthile obukhulu, ngaphezulu kwe-1.8, kwaye uninzi lweemveliso ze-CR ECO zinomlinganiselo omkhulu ngaphezu kwe-1.3.Ezi glues zinokuqwalaselwa.
5. Indlela yokushisa ephantsi
Thatha isampuli kwimveliso egqityiweyo kwaye usebenzise umkhenkce owomileyo kunye notywala ukuze wenze indawo efanelekileyo ye-cryogenic.Gcoba isampuli kwindawo yokushisa ephantsi kwemizuzu emi-2-5, uzive uthambile kunye nobunzima kwiqondo lokushisa elikhethiweyo.Ngokomzekelo, kwi-degrees -40, ukushisa okufanayo kunye nokumelana neoli ye-silica gel kunye nerubha ye-fluorine ifaniswa, kwaye i-silica gel ithambile.
