1. Ukumelana novavanyo lokutyeba okuphakathi
Imveliso egqityiweyo ingathathwa iisampulu, ifakwe kwisixhobo esinye okanye ezininzi ezikhethiweyo, ilinganiswe emva kobushushu obuthile kunye nexesha elithile, kwaye uhlobo lwezinto lunokuqikelelwa ngokwezinga lokutshintsha kobunzima kunye nezinga lokutshintsha kobunzima.
Umzekelo, xa ifakwa kwi-oyile ye-100 degrees iiyure ezingama-24, i-NBR, irabha ye-fluorine, i-ECO, i-CR inotshintsho oluncinci kumgangatho kunye nobunzima, ngelixa i-NR, i-EPDM, i-SBR iphindwe kabini ngobunzima kwaye itshintsha kakhulu ubunzima, kwaye ukwandiswa komthamo kuyabonakala.
2. Uvavanyo lokwaluphala komoya oshushu
Thatha iisampulu kwiimveliso ezigqityiweyo, uzifake ebhokisini yokwaluphala usuku olunye, uze ujonge le nto emva kokwaluphala. Ukwaluphala kancinci kancinci kunokwandiswa kancinci kancinci. Umzekelo, i-CR, i-NR, kunye ne-SBR ziya kuba buthathaka kwi-150 degrees, ngelixa i-NBR EPDM isathambile. Xa ubushushu bunyuka ukuya kwi-180 degrees, i-NBR eqhelekileyo iya kuba buthathaka; kwaye i-HNBR nayo iya kuba buthathaka kwi-230 degrees, kwaye irabha ye-fluorine kunye ne-silicone zisenokuqina okuhle.
3. Indlela yokutsha
Thabatha isampuli encinci uyitshise emoyeni. Jonga le nto.
Ngokubanzi, irabha ye-fluorine, i-CR, i-CSM azinamlilo, kwaye nokuba ilangabi liyatsha, lincinci kakhulu kune-NR kunye ne-EPDM eqhelekileyo. Ewe kona, ukuba sijonga ngokusondeleyo, imeko yokutsha, umbala, kunye nevumba nazo zisinika ulwazi oluninzi. Umzekelo, xa i-NBR/PVC idityaniswe neglu, xa kukho umthombo womlilo, umlilo uyatshaza kwaye ubonakala ngathi ufana namanzi. Kufuneka kuqatshelwe ukuba ngamanye amaxesha iglu ethintela ilangabi kodwa engenalo i-halogen nayo iya kuzicima emlilweni, nto leyo ekufuneka iqondwe ngakumbi ngezinye iindlela.
4. Ukulinganisa ubunzima obuthile
Sebenzisa isikali se-elektroniki okanye ibhalansi yohlalutyo, echanekileyo ukuya kwi-0.01 gram, kunye neglasi yamanzi kunye neenwele.
Ngokubanzi, irabha ye-fluorine inomxhuzulane omkhulu, ongaphezulu kwe-1.8, kwaye uninzi lweemveliso ze-CR ECO zinomlinganiselo omkhulu ongaphezulu kwe-1.3. Ezi glue zinokuqwalaselwa.
5. Indlela yobushushu obuphantsi
Thatha isampuli kwimveliso egqityiweyo uze usebenzise umkhenkce owomileyo kunye notywala ukuze wenze indawo efanelekileyo yokukhanya. Nciphisa isampuli kwindawo yobushushu obuphantsi imizuzu emi-2-5, uzive uthambile kwaye uqine kubushushu obukhethiweyo. Umzekelo, kwi--40 degrees, kuthelekiswa ubushushu obufanayo kunye ne-oli ye-silica gel kunye nerabha ye-fluorine, kwaye i-silica gel ithambile.
