Plumber's (Teflon) Daim kab xev yog dab tsi?
Plumber daim kab xev los yog Teflon daim kab xev yog ib tug polymer ua los ntawm polytetrafluoroethylene (PTFE). Teflon yog lub npe lag luam npe Chemours (yav tas los Dupont) muaj rau cov polymer. Koj tsis tuaj yeem pom cov khoom hu ua "Teflon daim kab xev" ntawm cov txee; xwb, nws tau sau tias "xov foob" lossis "xov-sealing" daim kab xev. Cov teeb meem tsis meej pem, "plumber's tape" yog ib lub npe siv rau cov hlau lossis yas strapping siv los txhawb cov yeeb nkab. Tsis tas li ntawd, nco ntsoov tias tus kav dej cov kab xev yog ib yam khoom sib txawv tshaj li tus kav dej lub putty.
Plumber daim kab xev yog ib qho yooj yim thiab nyab xeeb nyob rau hauv ntau daim ntawv thov, tab sis muaj txoj cai thiab tsis ncaj ncees lawm siv nws. Tsis tas li ntawd, nco ntsoov nws tsis pom zoo rau PVC, qee qhov tooj liab fittings, PEX kav, lossis poj niam kawg ntawm kev sib txuas. Cov kav dej thiab roj sib txuas uas siv cov hlau tsis muaj steel, tooj dag, thiab hlau feem ntau yog siv nrog cov kav dej cov kab xev. Raws li ib txwm muaj, xyuas kom koj ncua mus rau cov chaw tsim khoom ntim cov lus qhia txog kev siv cov kav dej cov kab xev ntawm cov yeeb nkab tshwj xeeb.
Ua ntej Koj Pib
Tsis yog txhua tus kav dej (Teflon) daim kab xev yog tib yam. Ua ntej tuav lub yob, tau qhov zoo rau koj cov kev xav tau. Cov kab xev no yog xim xim raws li lawv siv. Nov yog qhov txawv ntawm lawv:
Dawb los yog liab kab xev: Feem ntau siv los ntawm cov kav dej thiab cov yeeb nkab haum rau cov kab dej; dawb yog hom ntau dua; paj yeeb yog sturdier thiab feem ntau siv los ntawm cov yeeb nkab fitters
Daim kab xev daj: Siv rau cov kab roj; ua tau raws li lub tuam txhab roj cov qauv rau propane, butane, thiab natural gas
Daim kab xev ntsuab: Siv rau cov pa oxygen; roj-dawb thiab tsis-combustible nyob ib ncig ntawm oxygen
Grey daim kab xev: Siv rau stainless hlau fittings; muaj ib tug high-density ntsuam xyuas, yuav luag ob npaug rau thickness ntawm lwm threading tapes; tiv thaiv seizing thiab galling
Daim kab xev xiav: Ib daim kab xev tshaj lij siv los kaw cov pa roj, cua, thiab cov kab dej
Kev xav txog kev nyab xeeb
Kev siv ntau dhau los yog siv cov xov tsis zoo yuav ua rau muaj kev phom sij. Tsis txhob siv ntau tshaj li rau lub wrappings nyob ib ncig ntawm ib tug threading. Daim ntawv thov ntau dhau ntawm daim kab xev tuaj yeem tiv thaiv cov mating ntawm cov xov, ua rau shearing lossis tawg ntawm cov xov.
Overheating threading los yog Teflon ntawm qhov kub thiab txias nyob rau hauv cov ntawv thov kev lag luam tuaj yeem tsim cov tshuaj perfluoroisobutene, cov pa roj lom thiab muaj peev xwm ua rau tuag taus.
Cov lus qhia rau kev siv cov kav dej (Teflon) Daim kab xev
Qhov ua kom yuam kev siv Teflon daim kab xev kom zoo yog qhwv nws ncig cov yeeb nkab kom raug. Thaum cov yeeb nkab tig mus rau hauv qhov haum, kev sib txhuam ntawm cov mating threads yuav tsum ua hauj lwm kom nruj daim kab xev nyob ib ncig ntawm cov yeeb nkab es tsis ua hauj lwm tiv thaiv nws thiab unravel los yog pob li daim kab xev.
qhwv daim kab xev nyob ib ncig ntawm cov yeeb nkab nyob rau hauv tib lub clockwise kev taw qhia li cas cov yeeb nkab yuav tig mus rau hauv lub haum. Ua li no, nws yuav tsis unravel thaum sib koom ua ke.
Ntxuav cov yeeb nkab
Ntxuav cov txiv neej threads ntawm qhov kawg ntawm cov yeeb nkab nrog ib daim ntaub huv.
Kab kab yeeb nkab thiab kab xev
Muab qhov kawg ntawm tus kav dej daim kab xev rau ntawm xov thib ob los ntawm qhov kawg ntawm cov yeeb nkab thiab tuav nws hauv qhov chaw nrog tus ntiv tes lossis ntiv tes xoo. Daim kab xev yuav tsum pw tiaj tus (tsis yog bunched) hla cov xov thiab txuas perpendicularly mus rau qhov ntev ntawm cov yeeb nkab.
Qhwv daim kab xev
Pib qhwv daim kab xev nyob ib ncig ntawm cov yeeb nkab nyob rau hauv tib txoj kev raws li cov kev taw qhia cov yeeb nkab yuav tig.
Plumber daim kab xev qhwv ib ncig ntawm cov yeeb nkab kawg nyob rau hauv opposite direction
Khaws daim kab xev nruj
Khaws nro ntawm daim kab xev kom nws qhwv snugly nyob ib ncig ntawm cov yeeb nkab. Ua hauj lwm deb ntawm qhov kawg ntawm cov yeeb nkab, overlapping daim kab xev raws li koj mus.
Qhwv plaub mus rau rau lub sij hawm
Ua kom tiav plaub mus rau rau qhov qhwv ib ncig ntawm cov yeeb nkab, ua tiav ze ntawm qhov kawg ntawm cov xov (piv txwv li qhov kawg ntawm cov yeeb nkab).
Txhaum daim kab xev
Txiav daim kab xev los ntawm yob los ntawm kev tuav nws ntawm tus ntiv tes xoo thiab forefinger thiab rub sharply; nws tawg yooj yim. Smooth xoob xaus rau ntawm threads. Cov yeeb nkab tam sim no npaj mus rau hauv qhov haum.
