Uzama ukuodola iivalvu, kodwa omnye umthengisi ubabiza ngokuba yiPVC kwaye omnye ubabiza ngokuba yiUPVC. Oku kubhideka kukwenza ube nexhala xa uthelekisa iimveliso ezahlukeneyo okanye uthenga imathiriyeli engalunganga.
Kwiivalvu zebhola ezomeleleyo, akukho mahluko usebenzayo phakathi kwePVC kunye ne-UPVC. Omabini la magama abhekisa kwinto enyeizinto zepolyvinyl chloride ezingaxutywanga, eyomeleleyo, enganyangekiyo kwi-corrosion, kwaye ilungele iinkqubo zamanzi.
Lo ngomnye weyona mibuzo ixhaphakileyo endiyifumanayo, kwaye idala ukubhideka okungeyomfuneko kwikhonkco lonikezelo. Bendisandula ukuthetha noBudi, umphathi wokuthenga osuka kumsasazi omkhulu waseIndonesia. Abathengi bakhe abatsha abancinci babebambekile, becinga ukuba kufuneka bafumane iindidi ezimbini zeevalvu. Ndamchazela ukuba iivalve eziqinileyo esizenzayo ePntek, kwaye kuninzi lweshishini, amagama asetyenziswa ngokungafaniyo. Ukuqonda ukuba kutheni kuya kukunika ukuzithemba kwizigqibo zakho zokuthenga.
Ngaba kukho umahluko phakathi kwePVC kunye neUPVC?
Ubona ii-acronyms ezimbini ezahlukeneyo kwaye ngokwemvelo ucinga ukuba zimele izinto ezimbini ezahlukeneyo. La mathandabuzo angacothisa iiprojekthi zakho njengoko uzama ukuqinisekisa iinkcukacha ezichanekileyo.
Ngokwenene, hayi. Kwimibhobho enzima kunye neevalve, i-PVC kunye ne-UPVC ziyafana. I-"U" kwi-UPVC imele "i-unplasticized," esele iyinyani kuzo zonke iivalvu ze-PVC eziqinileyo.
Ukubhideka kuvela kwimbali yeeplastiki. I-Polyvinyl chloride (PVC) yinto esisiseko. Ukwenza ukuba ibe bhetyebhetye kwiimveliso ezifana nemibhobho yegadi okanye ukugqunywa kocingo lombane, abavelisi bongeza izinto ezibizwa ngokuba ziiplastiki. Ukwahlula i-original, ifom eqinile kwi-flexible version, igama elithi "unplasticized" okanye "UPVC" lavela. Nangona kunjalo, kwizicelo ezinje ngeenkqubo zamanzi ezinoxinzelelo, awusoze usebenzise inguqulelo eguquguqukayo. Yonke imibhobho eqinileyo yePVC, izifakelo, kunye neevalvu zebhola, ngokwendalo yazo, azinaplastiki. Ke, ngelixa ezinye iinkampani zibhala imveliso yazo “i-UPVC” ukuba icace ngakumbi, kwaye ezinye zisebenzisa nje eyona ixhaphakileyo i-“PVC,” zibhekisa kweyona mathiriyeli yomeleleyo, eyomeleleyo. EPntek, sibabiza ngokululaIivalvu zebhola zePVCkuba lelona xesha lixhaphakileyo, kodwa zonke ziyi-UPVC yobuchwephesha.
Ngaba iivalvu zebhola zePVC zilungile?
Uyabona ukuba iPVC yiplastiki kwaye ixabisa ngaphantsi kwentsimbi. Oku kukwenza ukuba ubuze umgangatho wayo kwaye uzibuze ukuba yomelele ngokwaneleyo kwizicelo zakho ezinzulu, zexesha elide.
Ewe, iivalvu zebhola zePVC ezikumgangatho ophezulu zigqwesile ngokwenjongo yazo. Abakhuselekanga kwi-rust kunye ne-corrosion, i-lightweight, kwaye inikezela ubomi benkonzo ixesha elide kwizicelo zamanzi abandayo, zihlala zigqithisa iivalve zetsimbi.
Ixabiso labo alikho nje kwiindleko zabo eziphantsi; kukusebenza kwabo kwindawo ezithile. Iivalvu zesinyithi, ezifana nobhedu okanye intsimbi, ziya kuhlwa okanye zigqwese ngokuhamba kwexesha, ngakumbi kwiinkqubo ezinamanzi acociweyo, amanzi etyuwa, okanye iikhemikhali ezithile. Lo mhlwa unokubangela ukuba ivalve ibambe phezulu, nto leyo eyenza kube nzima ukujika xa kukho unxunguphalo. I-PVC ayikwazi ukugqwala. Isebenza ngekhemikhali kuninzi lwezongezo zamanzi, iityuwa, kunye neeasidi ezithambileyo. Yiyo loo nto abathengi bakaBudi kushishino lwaselwandle lwaselwandle e-Indonesia besebenzisa iivalvu zePVC kuphela. Amanzi anetyuwa angatshabalalisa iivalvu zentsimbi kwiminyaka nje embalwa, kodwa iivalvu zethu zePVC ziyaqhubeka nokusebenza kakuhle ishumi leminyaka nangaphezulu. Nasiphi na isicelo esingaphantsi kwe-60 ° C (140 ° F), aIvalve yebhola yePVCayilokhetho nje “elingabizi kakhulu”; kusoloko lolona khetho luthembekileyo noluthatha ixesha elide kuba ayisokuze ihluthe kumhlwa.
Loluphi olona hlobo lulungileyo lwevalvu yebhola?
Ufuna ukuthenga ivalve “egqwesileyo” ukuqinisekisa ukuba inkqubo yakho ithembekile. Kodwa ngezixhobo ezininzi ezikhoyo, ukukhetha eyona nto ingcono kakhulu iziva inzima kwaye iyingozi.
Akukho valve yebhola “egqwesileyo” kuwo wonke umsebenzi. Eyona valve ilungileyo yileyo inemathiriyeli kunye noyilo oluhambelana ngokugqibeleleyo nobushushu benkqubo yakho, uxinzelelo, kunye nokusingqongileyo kwemichiza.
"Eyona nto ingcono" ihlala inxulumene nesicelo. Ukukhetha ephosakeleyo kufana nokusebenzisa inqwelo-mafutha ekutsaleni igrabile—sisixhobo esingafanelekanga somsebenzi. Ivalve yensimbi engenastainless ilungile kubushushu obuphezulu kunye noxinzelelo, kodwa kubiza kakhulu ukugqithiswa kwenkqubo yokujikeleza echibini, apho ivalve ye-PVC iphezulu ngenxa yomgangatho wayo.ukumelana neklorine. Ndihlala ndikhokela amaqabane am ukuba acinge ngeemeko ezithile zeprojekthi yabo. Ivalve ye-PVC yintshatsheli yeenkqubo zamanzi abandayo ngenxa yokumelana nokubola kunye neendleko. Kumanzi ashushu, kufuneka unyuke ukuyaCPVC. Kwi-high-pressure gas okanye ioli, ubhedu lukhetho lwendabuko, oluthembekileyo. Ukusetyenziswa komgangatho wokutya okanye iikhemikhali ezinobungozi kakhulu, isinyithi esingenasici sihlala sifuneka. Eyona nto "elungileyo" ukhetho lolona lubonelela ngokhuseleko olufunekayo kunye nobomi obude ngexabiso eliphantsi lilonke.

Yintoni umahluko phakathi kwePVC U kunye neUPVC?
Kanye xa ucinga ukuba uyayiqonda i-PVC vs. UPVC, ubona "i-PVC-U" kuxwebhu lobugcisa. Eli gama litsha longeza omnye umaleko wokubhideka, likwenza uqikelele ukuqonda kwakho.
Akukho mahluko kwaphela. IPVC-U yenye indlela yokubhala iPVC. Igama elithi “-U” likwamele i-unplasticized. Yingqungquthela yamagama ehlala ibonwa kwimigangatho yaseYurophu okanye yamazwe ngamazwe (njenge-DIN okanye i-ISO).
Yicinge njengokutsho "i-100 yeedola" ngokuchasene "ne-100 yeedola." Ngamagama ahlukeneyo ento enye. Kwihlabathi leeplastiki, imimandla eyahlukeneyo iphuhlise iindlela ezahlukeneyo zokulebhelisha ezi zinto. ENyakatho Melika, "i-PVC" ligama eliqhelekileyo lombhobho oqinileyo, kwaye "UPVC" ngamanye amaxesha isetyenziselwa ukucaca. EYurophu naphantsi kwemigangatho yamazwe ngamazwe, “i-PVC-U” lelona gama lobunjineli lisesikweni ukucacisa “elingenaplastiki.” Kumthengi ofana noBudi, eli licandelo elibalulekileyo lolwazi kwiqela lakhe. Xa bebona ithenda yaseYurophu echaza iivalvu ze-PVC-U, bayazi ngokuzithemba ukuba i-valve yethu ye-PVC eqhelekileyo ihlangabezana neemfuno ngokugqibeleleyo. Konke kuhla kwizinto ezifanayo: i-polymer eqinile, eyomeleleyo, engafakwanga iplastiki elungele iivalvu zebhola. Musa ukubanjiswa ngoonobumba; kugxilwe kwiipropati zezinto kunye nemigangatho yokusebenza.
Ukuqukumbela
I-PVC, i-UPVC, kunye ne-PVC-U zonke zibhekisela kwizinto ezifanayo eziqinileyo, ezingenaplastiki ezifanelekileyo kwiivalvu zebhola zamanzi abandayo. Umahluko wamagama ziindibano zengingqi okanye zembali.
