Kwimichiza yeelebhu kunye neendawo zokuhlala, ukuqinisekisa ukuhambelana phakathi kweesampulu kwaye Septa yeyona nto iphambili ekugcineni ukusebenza ngokufanelekileyo nangokukhuselekileyo. Oku kufuna ukuba kuqinisekiswe kakuhle ukuba ziqhuba njani izicoci ezithile kunye neentengo Septa izixhoboI-polytetrafluororororoothyyyyyyyyyyyyyyyyyyyyyyyyyeyley (ptfe) kunye ne-silicone, enokubangela ukonakaliswa kwe-gasket kunye nokuchitheka, kwaye ekugqibeleni kuchaphazela ukusebenza kakuhle.

Ukuhambelana nePolytetrafluoroothylene (PTFE)

I-Polytetraflioroothyyyyyyyyyyyyyyyyyyyyyyyyyyyyyeyyyyyeyyyyyeyyyyyeyyyyyyeyyyyyyyyyeyyyyyyeyyyyyyeyyyyyyye (PTFE), exhaswanga njenge-teflon, yindawo eguquguqukayo esetyenziswe ngokubanzi kwi-gasket ngenxa yokungaxhathisi iikhemidi zekhemikhali kunye nepropathi engasebenziyo. I-PTFO ichasa uluhlu olubanzi lwee-slis, kubandakanya i-hydrocarbons, ilokishi, kwaye uninzi lwe-asidi kunye neziseko. Oku kwenza ukhetho olufanelekileyo lokwenza izicelo zokutywina apho kulindeleke ukuba kungabonakali kwiikhemikhali zobundlobongela.

Nangona kunjalo, ngaphandle kokuxhathisa imichiza eyomeleleyo, i-PTKI inokufaneleka okulinganiselweyo kwiimeko ezithile. Umzekelo, ii-oxichers ezinamandla ezinje nge-sulfuric acid, i-nitric acid, okanye ii-haloogens ezinje nge-chlorine okanye i-chiner efana ne-chlorine okanye i-fluorine comples zinokuqalisa ukuphendula kwekhemikhali nge-ptfe. Ezi zinto zinokwenzeka zinokubangelaIirhasi ze-ptfeukuphelisa kwaye uphulukane nokusebenza kwabo ngokuhamba kwexesha.

Kubalulekile ukuba uqonde iindlela ezithile apho kudibana khona ezikhemikhali. Umzekelo, i-sulfuric acid egxile kwi-sulfuric inokubangela i-ptfe ukuqhubela phambili, ekhokelela ekumiselweni kwe-hydrofluoricioric acid kunye nendawo yentsalela ye-carbonaceous enokuthi ityeshele ingqibelelo yezinto zeperket. Ngokufanayo, i-nitric acid inokubangela ukonakaliswa kwe-oxidas ye-PTFE, echaphazela iipropathi zayo kunye nokusebenza.

Uvavanyo kunye novavanyo oluchanekileyo lubalulekile ukulungisa ezi mingeni. Oku kubandakanya ukuhlengahlengiswa kweetshathi zekhephu kunye neenkcukacha zolwazi kunye neenkcukacha zokuvavanya umngcipheko onokubakho onxulumene nokusetyenziswa kwe-ptfe Septa kwiindawo ezinamaphepha ezimo eziqulathe ii-oxidizers. Ukongeza, uvavanyo olulawulwayo olulawulwa, apho iisampulu ezincinci ze-ptfe ziveze kwiikhemikhali zethagethi eziphantsi kweemeko ezijongwayo, zinokubonelela ngengqondo ebonakalayo kwintsebenzo kunye nokuqina komxholo.

I-Silicone ngokuhambelana

I-Silicone yenye imibandela esetyenziswa ngokubanzi kwiirhasi kwaye ixabiswe kakhulu ngokuguquguquka, ukumelana nobushushu obuphezulu, kunye nobuchule obucacileyo bokutywina.I-Silicone Seppaszisetyenziswa rhoqo kwizicelo apho bhetyebhetye kunye nokuqina kubalulekile, njengamatywina lwe-automotive, izixhobo zonyango, kunye nezixhobo zokutya.

I-Silicones ihambelane kakuhle neekhemikhali ezininzi kunye nezinyibilikisi, kodwa ezinye zinokubangela iingxaki zokungqinelana. Umzekelo, ama-silicones anokungafaneleki ukuba asetyenziswe nge-hydrocarbons evuthuzayo, i-acids eqinileyo njenge-sulfuric acid okanye i-hydrochloric acid, kunye neeoyile ezithile kunye nee-oyile.

Unxibelelwano lwe-silicone ngezixhobo ezingahambelaniyo zinokubangela ukungcungcutheka, ukuthambisa, okanye ukonakaliswa kwento yepetroli. Oku kunokuphawula ukusebenza kwendlela, kubangela ukuvuza, kunye neenkqubo ezingcolisekileyo kunye nezixhobo.

Ukuqinisekisa ukuba kufanelekile ukuba baqwalasele izinto ezinje ngexinzelelo lwekhemikhali, ubushushu, kunye nokuvezwa kwexesha kwimeko yokusebenza. Ukuqhuba iimvavanyo zokuhambelana kusetyenziswa iisampulu ezincinci zeraki ze-silicone zivele kwiikhemikhali ezimele iikhemikhali kunokunceda ukuvavanya ukusebenza kwezinto kunye nokufaneleka kwesicelo esijongwayo.

Ukulungiswa kunye nokuhlolwa

Ukongeza ekukhetheni izixhobo ze-galtikis ezihambelanayo, iinkqubo zokuhlola rhoqo kunye nokuhlola kubalulekile ukuqinisekisa ukusebenza kwexesha elide lokutywina kunye nokunyaniseka kwenkqubo. Oku:

Vavanya i-septa yeempawu zokunxiba, umonakalo, okanye ukonakala ngexesha lokuhlolwa kwesondlo.

Ukubeka iliso kutshintsho ekutyhalweni kwempumelelo, njengokuvuza okanye uxinzelelo oluguqukayo, olunokubonisa Septa iingxaki.

Ukumiliselwa kweshedyuli yolondolozo yoThintelo kunye nokutshintsha Septa Ngaphambi kokuba bafikelele esiphelweni sobomi babo obuluncedo okanye babonisa iimpawu zokuwohloka.

Ngokuthatha indlela yokufezekiswa kokuhambelana kwekhemikhali, ukukhetha izinto eziphathekayo kunye nokulungiswa, imibutho inokunciphisa umngcipheko onxulumene nayo Septa Ukungaphumeleli, kuqinisekiswe ukuthembeka okusebenzayo, kunye nokugcina imigangatho yezokhuseleko kwiinkqubo zabo.
