Emikhakheni yamakhemikhali nasezindaweni zezimboni, ukuqinisekisa ukuhambisana phakathi kwamasampula futhi upende kubaluleke kakhulu ukugcina ukusebenza okusebenzayo nokuphephile. Lokhu kudinga ukuqonda okuningiliziwe kokuthi i-solvents ethile kanye namakhompiyutha axhumana ngayo upende izinto zokwakhanjenge-polytetrafluoroethylene (PTFE) kanye ne-silicone, engadala ukonakaliswa kwe-gasket nokuchithwa, futhi ekugcineni kuthinte ukusebenza kokubekwa uphawu.

Ukuvumelana nePolytetrafluoroethylene (PTFE)

I-PolyteTrafluoroethylene (PTFE), eyaziwa kakhulu ngokuthi yiTeflon, iyinto eguquguqukayo esetshenziswa kabanzi kuma-gaskets ngenxa yokumelana kwayo okuhle kwamakhemikhali kanye nezakhiwo ezingasebenzi. I-PTFE imelana nohlu oluhlukahlukene lwe-solvents, kufaka phakathi ama-hydrocarbons, ama-alcohols, kanye nama-acid amaningi nezisekelo. Lokhu kwenza kube yikhethelo elihle lokufaka isicelo sokubekwa uphawu lapho kulindelwe khona amakhemikhali anolaka.

Kodwa-ke, naphezu kokumelana kwamakhemikhali okuqinile, i-PTFE ingahle ibe nokufaneleka okulinganiselwe ezimweni ezithile. Isibonelo, ama-oxidizers aqinile afana ne-sulfuric acid ehlanganisiwe, i-nitric acid, noma ama-halogens anjenge-chlorine noma ama-fluorine angaqala ukusabela kwamakhemikhali nge-PTFE. Lokhu kusabela kungadalaAma-Gaskets we-PTFEukwehlisa futhi ulahlekelwe ukusebenza kwabo kokubopha ngokuhamba kwesikhathi ngokuhamba kwesikhathi.

Kubalulekile ukuqonda izindlela ezithile lapho la makhemikhali ahlangana khona ne-PTFE. Isibonelo, i-sulfuric acid egxilile ingadala ukuthi i-PTFE ibe yi-defluoridize, okuholela ekwakhekeni kwe-hydrofluoric acid kanye nezinsalela ze-carbonaceous ezingabeka engcupheni ngokwethembeka kwezinto ze-gasket. Ngokufanayo, i-nitric acid ingadala ukonakaliswa kwe-oxidative of PTFE, okuthinta izakhiwo zayo zemishini nokusebenza uphawu.

Ukuhlola ngokuphelele nokuhlola kubalulekile ukubhekana nalezi zinselelo zokuhambisana. Lokhu kufaka phakathi ukubhekisela amashadi okuhambisana namakhemikhali wokuhlola izingozi ezingaba khona ezihambisana nokusetshenziswa kwe-PTFE upende ezindaweni eziqukethe ama-oxidizers. Ngaphezu kwalokho, ukuhlolwa okuvezwa okulawulwayo, lapho amasampula amancane e-PTFE avezwa khona amakhemikhali aqondiwe ngaphansi kwezimo ezibhekwe, anganikeza ukuqonda okubalulekile ngokusebenza nokuqina kwezinto ezibonakalayo.

Abicah ukufana

I-Silicone kungenye into esetshenziswa kabanzi kuma-gaskets futhi ibaluleke kakhulu ngokuguquguquka kwayo, ukumelana okushisa okuphezulu, kanye nekhono elihle kakhulu lokubopha uphawu.Silicone Sepaszisetshenziswa kakhulu kuzinhlelo zokusebenza lapho ukuguquguquka nokuqina kubalulekile, njengezimpawu zezimoto, amadivaysi ezokwelapha, nemishini yokusebenza kokudla.

Ama-Silicone ahambisana kahle namakhemikhali amaningi nama-sol, kepha ezinye izinto zingadala izinkinga zokuhambisana. Isibonelo, izilolico kungenzeka zingakulungeli ukusetshenziswa nge-aromatic hydrocarbons, ama-acid anamandla anjenge-sulfuric noma i-hydrochloric acid, namafutha athile.

Ukuxhumana kwe-silicone ngezinto ezingahambelani kungadala ukuvuvukala, ukuthambisa, noma ukucekelwa phansi kwezinto ze-gasket. Lokhu kungaphazamisa ukusebenza kokubopha uphawu, kubangele ukuvuza, futhi kungcolise izinqubo nemishini.

Ukuqinisekisa ukuhambisana okulungile, kubalulekile ukubheka izinto ezifana nokuhlushwa kwamakhemikhali, izinga lokushisa, nesikhathi sokuvezwa endaweni yokusebenza. Ukwenza izivivinyo zokuhambisana usebenzisa amasampula amancane we-silicone gasket avezwa amakhemikhali amelele angasiza ukuhlola ukusebenza kwezinto ezibonakalayo kanye nokufaneleka kohlelo lokusebenza okuhlosiwe.

Ukulungiswa nokuhlola

Ngaphezu kokukhetha izinto ezihambisanayo ze-gasket, ukulungiswa njalo kanye nemikhuba yokuhlola kubalulekile ukuqinisekisa ukusebenza kokubekwa uphawu kwesikhathi eside nokwethembeka kohlelo. Futhi lokhu:

Hlola Septhemba ngezinkinga zokugqoka, ukulimala, noma ukonakala ngesikhathi sokuhlolwa kwezimali ezijwayelekile.

Gada izinguquko ekusebenzeni kokubekwa uphawu, njengokushintshashintsha kwengcindezi, okungakhombisa upende Izinkinga.

Sebenzisa uhlelo lokulondolozwa kokuvimbela bese ubuyisela kabusha upende ngaphambi kokuba bafinyelele ekugcineni kwempilo yabo ewusizo noma babonise izimpawu zokuwohloka.

Ngokuthatha indlela esebenzayo ekuvumelaneni kwamakhemikhali, ukukhethwa kwezinto ezibonakalayo, kanye nokunakekelwa, izinhlangano zinganciphisa ubungozi obuhambisana upende Ukwehluleka, kuqinisekisa ukuthembeka okusebenzayo, futhi kugcinwe ukuphepha kanye namazinga wezemvelo ezinqubweni zawo.
