Ukuphila kwayo ixesha elide kuxhomekeke kumgangatho, ukusetyenziswa kwayo, kunye nendawo engqongileyo.
Lo mbuzo uphambili kwinto esiyenzayo. Ndikhumbula incoko noBudi, iqabane lethu eliphambili lokusasaza e-Indonesia. Omnye wabathengi bakhe, iqumrhu elikhulu lezolimo, wayethandabuza ukusebenzisa i-intanethi yethu.Iivalvu zePVC. Babeqhele ukutshintsha iivalvu zabo zesinyithi ezibolileyo rhoqo emva kweminyaka embalwa kwaye babengakholelwa ukuba ivalvu "yeplastiki" ingahlala ixesha elide. UBudi wabacenga ukuba bazame ezimbalwa kwiindlela zabo zokunkcenkceshela ezininzi ezinezichumisi. Oko kwenzeka kwiminyaka esixhenxe eyadlulayo. Ndamjonga kwinyanga ephelileyo, waza wandixelela ukuba ezo valve zifanayo zisasebenza ngokugqibeleleyo. Azikatshintshi nenye. Nguwo lowo umahluko owenza umgangatho.
Ingakanani ixesha lokuphila kwevalvu yebhola yePVC?
Kufuneka ucwangcise iindleko zokulungisa nezokutshintsha. Ukusebenzisa inxalenye enokuhlala ixesha elide kuyenza ibhajethi yakho ibe luqikelelo olupheleleyo kwaye kunokubangela ukungaphumeleli okungalindelekanga ekuhambeni kwexesha.
Ubomi benkonzo obulindelekileyo bevalvu yebhola yePVC esemgangathweni buhlala buyiminyaka eli-10 ukuya kwengama-20. Nangona kunjalo, kwiimeko ezifanelekileyo—ngaphakathi, emanzini abandayo, ukusetyenziswa rhoqo—inokuhlala ixesha elide. Izinto ezibalulekileyo zingumgangatho wezinto ezibonakalayo, ukuvezwa yi-UV, kunye noxinzelelo lokusebenza.
Ubomi bevalvu abuyonto inye; bubangelwa zizinto ezininzi ezibalulekileyo. Eyona nto ibalulekileyo zizinto ezisetyenziswayo. KwiPntek, sisebenzisa kuphela i-resin ye-PVC eyi-100% eyi-virgin. Oku kuqinisekisa amandla aphezulu kunye nokumelana neekhemikhali. Iivalvu ezingabizi kakhulu zihlala zisebenzisa“phinda ucofe” (i-PVC ephinde yasetyenziswa), enokuba buthathaka kwaye ingaqikeleleki. Enye into enkulu kukuvezwa yi-UV elangeni. I-PVC eqhelekileyo inokuba buthathaka ngokuhamba kwexesha ukuba ishiywe elangeni, yiyo loo nto sinikezela ngeemodeli ezithile ezimelana ne-UV zokusetyenziswa ngaphandle njengokunkcenkceshela. Okokugqibela, cinga ngezitywini. Sisebenzisa izitulo ze-PTFE ezihlala ixesha elide ezibonelela ngesitywini esigudileyo, esincinci esimelana namawaka eenguqu. Iivalvu ezingabizi kakhulu ezinezitywini zerabha eziqhelekileyo ziya kuguga ngokukhawuleza. Ukutyala imali kumgangatho osemgangathweni kwangaphambili yeyona ndlela iqinisekileyo yokuqinisekisa ubomi obude.
