Ukukhetha phakathi kwe-CPVC kunye ne-PVC kunokukwenza okanye ukwaphule inkqubo yakho ye-plumbing. Ukusebenzisa izinto ezingafanelekanga kunokukhokelela ekusileleni, ekuvuzeni, okanye kwaneziqhushumbisi eziyingozi phantsi koxinzelelo.

Umahluko omkhulu ukunyamezela ukushisa - i-CPVC ibamba amanzi ashushu ukuya kwi-93 ° C (200 ° F) ngelixa i-PVC inqunyelwe kwi-60 ° C (140 ° F). Iivalvu ze-CPVC nazo zibiza kancinane kwaye zinoxhathiso olungcono lwekhemikhali ngenxa yolwakhiwo lwazo lweklorini.

Ukuqala nje kokubona, ezi zivalo zeplastiki zikhangeleka zifana ngokufanayo. Kodwa iyantlukwano yabo yeemolekyuli idala izithuba ezibalulekileyo zokusebenza ekufuneka wonke umyili nomfakeli aziqonde. Kumsebenzi wam kunye nabathengi abaninzi abanjengoJacky, lo mahluko uhlala uvela xa ujongene nezicelo zamanzi ashushu apho umgangathoI-PVCiya kusilela. Iklorini eyongezelelweyo ngaphakathiCPVCinika iipropati eziphuculweyo ezithethelela ixabiso layo eliphezulu kwiimeko ezithile, ngelixa i-PVC eqhelekileyo ihleli ilukhetho loqoqosho kwiinkqubo zamanzi eziqhelekileyo.

Kwenzeka ntoni ukuba usebenzisa iPVC endaweni yeCPVC?

Umzuzwana wokonga iindleko unokukhokelela ekungaphumeleli kwentlekele. Ukukhetha i-PVC apho i-CPVC ifunwa imingcipheko yokulwa, ukuqhekeka, kunye nokulahleka koxinzelelo oluyingozi kwiinkqubo ezishushu.

Ukusebenzisa i-PVC kwizicelo zamanzi ashushu (ngaphezu kwe-60 ° C / 140 ° F) kuya kubangela ukuba iplastiki ithambe kwaye iguqulwe, ekhokelela ekuvuzeni okanye ukungaphumeleli ngokupheleleyo. Kwiimeko ezigqithisileyo, i-valve inokuqhuma kwixinzelelo xa iyancipha ngenxa yokushisa, okunokubangela umonakalo wamanzi kunye neengozi zokhuseleko.

Ndikhumbula imeko apho umxhasi kaJacky efake iivalvu zePVC kwi-dishwasher system yokuthengisa ukugcina imali. Kwiiveki nje ezimbalwa, iivalve zaqalisa ukujija nokuvuza. Iindleko zokulungisa zidlule kude kulo naluphi na ugcino lokuqala. Ulwakhiwo lwemolekyuli yePVC ayinakukwazi ukumelana namaqondo obushushu azinzileyo – amatyathanga eplastiki aqalisa ukuqhawuka. Ngokungafaniyo nemibhobho yentsimbi, oku kuthamba akubonakali de kwenzeke ukusilela. Yiyo loo nto iikhowudi zokwakha zilawula ngokungqongqo apho isixhobo ngasinye sinokusetyenziswa.

Ziziphi iingenelo zevalve yebhola yePVC?

Yonke iprojekthi ijongene noxinzelelo lohlahlo lwabiwo-mali, kodwa awukwazi ukuyekelela ekuthembekeni. Iivalvu zePVC zibetha ibhalansi egqibeleleyo apho iimeko zivumela.

Iivalvu zePVC zibonelela ngexabiso elingenakoyiswa, ukufakwa lula, kunye nokumelana nomhlwa okuphezulu xa kuthelekiswa nezinye iindlela zentsimbi. Ziyi-50-70% zitshiphu kune-CPVC ngelixa zibonelela ngokusebenza okugqwesileyo kwizicelo zamanzi abandayo.

Kwiinkqubo zamanzi abandayo, akukho xabiso lingcono kunePVC. Ukudityaniswa kwe-solvent-weld yabo kudala ukukhawuleza, ukudibanisa okuthe tye ngaphezu kwezixhobo zetsimbi ezixutywe, ukunciphisa iindleko zabasebenzi. Ngokungafaniyo nesinyithi, azikhe zidle okanye zakhe iidiphozithi zamaminerali. EPntek, siye sayila yethuIivalvu zePVCkunye namaqumrhu omeleziweyo agcina ingqibelelo yawo nasemva kwamashumi eminyaka esetyenziswa. Kwiiprojekthi ezifana noJacky'siinkqubo zokunkcenkceshela kwezolimoapho ubushushu abunangxaki, iPVC ihlala ilolona khetho lukrelekrele.

Kutheni i-CPVC ingasasetyenziswa?

Unokuva amabango okuba i-CPVC iya iphelelwa lixesha, kodwa inyaniso iyancipha ngakumbi. Ukuqhubela phambili kwezinto eziphathekayo akukhange kuziphelise iingenelo zayo ezizodwa.

I-CPVC isasetyenziswa ngokubanzi kodwa ithathelwe indawo yi-PEX kunye nezinye izinto kwezinye izicelo zokuhlala ngenxa yeendleko. Nangona kunjalo, ihlala ibalulekile kwiinkqubo zamanzi ashushu zorhwebo apho izinga layo eliphezulu lobushushu (93 ° C / 200 ° F) lidlula ezinye iindlela.

Ngelixa i-PEX ifumene ukuthandwa kwimibhobho yasekhaya, iCPVC igcina izikhundla ezomeleleyo kwiindawo ezintathu eziphambili:

1. Izakhiwo zorhwebo ezineenkqubo zamanzi ashushu ezisembindini
2. Izicelo zamashishini ezifunayoukumelana neekhemikhali
3. Iiprojekthi zokubuyisela ngokutsha ezihambelana neziseko ezingundoqo ezikhoyo ze-CPVC

Kwezi meko, ukukwazi kwe-CPVC ukuphatha ubushushu kunye noxinzelelo ngaphandle kwemiba yentsimbi ye-corrosion yenza ukuba ingabinandawo. Ingcinga yokuba iyanyamalala imalunga neeshifti zentengiso yendawo yokuhlala kunokuphelelwa ngamandla kobugcisa.

Ngaba izifakelo zePVC kunye neCPVC ziyahambelana?

Izinto zokuxuba zibonakala ziyindlela emfutshane elula, kodwa ukudibanisa okungafanelekanga kudala amanqaku abuthathaka abeka esichengeni iinkqubo zonke.

Hayi, azihambelani ngokuthe ngqo. Ngelixa bobabini besebenzisa i-welding ye-solvent, bafuna iisamente ezahlukeneyo (isamente yePVC ayiyi kudibanisa ngokufanelekileyo i-CPVC kwaye ngokuphambeneyo). Nangona kunjalo, izixhobo zenguqu ziyafumaneka ukudibanisa ngokukhuselekileyo izinto ezimbini.

Umahluko wokwakheka kweekhemikhali kuthetha ukuba iisamente zazo zokunyibilikisa azitshintshi:

• Isamente yePVC inyibilika umphezulu wePVC ukuze udibanise
• Isamente ye-CPVC yomelele ekuphenduleni ngesakhiwo sayo esinamandla ngakumbi

Ukuzama ukunyanzela ukuhambelana kukhokelela kumalungu abuthathaka anokuphumelela uvavanyo loxinzelelo ekuqaleni kodwa angaphumeleli ekuhambeni kwexesha. EPntek, sihlala sicebisa:

1. Ukusebenzisa isamente echanekileyo kuhlobo ngalunye lwemathiriyeli
2. Ukufakela izifakelo ezifanelekileyo zenguqu xa udibaniso luyimfuneko
3. Ukuleyibhela ngokucacileyo onke amacandelo ukuthintela ukuxubana

Ukuqukumbela

Iivalve zebhola ze-PVC kunye ne-CPVC zisebenza ngeendlela ezahlukeneyo kodwa zibaluleke ngokulinganayo-i-PVC kwiinkqubo zamanzi abandayo angabizi kakhulu kunye ne-CPVC yokufuna izicelo zamanzi ashushu. Ukukhetha ngokuchanekileyo kuqinisekisa ukusebenza okukhuselekileyo, okuhlala ixesha elide. Soloko udibanisa ivalve kubushushu obuthile benkqubo yakho kunye neemfuno zekhemikhali ukuze ufumane iziphumo ezizezona.
