Rau cov neeg soj ntsuam xws li, muaj qhov sib txawv me ntsis ntawm PVC yeeb nkab thiab uPVC yeeb nkab.Ob leeg yog cov yeeb nkab yas siv dav hauv tsev.Tshaj li qhov zoo sib xws, ob hom yeeb nkab yog tsim los sib txawv thiab yog li muaj cov khoom sib txawv thiab sib txawv me ntsis hauv kev tsim thiab lwm cov txheej txheem kev lag luam thiab feem ntau kho-ua hauj lwm raug rau cov yeeb nkab yas yog PVC es tsis yog uPVC.
Tsim
PVC thiab uPVC feem ntau yog ua los ntawm tib yam khoom.Polyvinylchloride yog ib qho polymer uas tuaj yeem ua kom sov thiab molded los tsim kom muaj zog, muaj zog sib txuas xws li piping.Vim tias nws cov khoom ruaj khov thaum nws tsim, cov tuam ntxhab feem ntau muab cov plasticizing polymers ntxiv rau hauv PVC.Cov polymers no ua rau cov yeeb nkab PVC ntau tuaj yeem kho tau thiab, feem ntau, yooj yim rau kev ua hauj lwm nrog ntau dua yog tias nws tseem tsis muaj yas.Cov neeg ua hauj lwm plasticizing raug tso tawm thaum uPVC yog tsim - lub npe luv rau unplasticized polyvinylchloride - uas yog ze li ntawm nruj li cam khwb cia hlau yeeb nkab.
tuav
Rau kev teeb tsa lub hom phiaj, PVC thiab uPVC yeeb nkab feem ntau yog ua tib yam nkaus.Ob leeg tuaj yeem txiav tau yooj yim nrog cov yas-txiav hack saw hniav lossis cov cuab yeej hluav taws xob tsim los txiav PVC yeeb nkab thiab ob qho tib si tau koom nrog siv cov sib txuas gluing es tsis yog los ntawm kev sib txuas.Vim tias uPVC yeeb nkab tsis muaj cov plasticizing polymers uas ua rau PVC hloov tau me ntsis, nws yuav tsum tau txiav kom loj me me vim nws tsis tso cai rau muab.
Daim ntawv thov
PVC yeeb nkab yog siv los hloov cov tooj liab thiab txhuas piping ntawm cov dej tsis muaj dej, hloov cov kav hlau hauv cov kab khib nyiab, cov kav dej thiab cov pas dej ua ke.Vim tias nws tiv taus corrosion thiab degradation los ntawm cov khoom siv roj ntsha, nws yog cov khoom siv ruaj khov siv hauv cov kav dej.Nws tau yooj yim txiav thiab nws cov pob qij txha tsis tas yuav tsum tau soldering, fastening nrog cov kua nplaum, thiab muab me ntsis ntawm qhov muab thaum cov kav dej tsis zoo, yog li PVC yeeb nkab feem ntau xaiv los ntawm handymen ua ib qho yooj yim-rau-siv lwm txoj rau hlau. kav dej.
Kev siv uPVC tsis zoo li thoob plaws hauv cov kav dej hauv Asmeskas, txawm hais tias nws cov kav ntev tau pab nws los ua cov khoom siv rau cov kav dej phwj tuaj, hloov cov yeeb nkab cam khwb cia hlau.Nws tseem nquag siv hauv kev tsim cov dej ntws tawm sab nrauv xws li nag gutter downspouts.
Tib hom yeeb nkab yas uas yuav tsum tau siv rau kev sib kis ntawm cov dej haus yog cPVC yeeb nkab.
