Siab Zoo PEX-AL-PEX Pipes

PEX -A, PEX-B, thiab PEX{2}}C txhais li cas

Thaum mus yuav khoom rau cross- txuas polyethylene piping, cov ntawv koj pom (A, B, C) xa mus rau txoj kev siv los hla -txuas cov yeeb nkab thaum tsim khoom, tsis yog qib zoo . PEX sawv cev rau cross- txuas polyethylene. Tus ntoo khaub lig-txuas txheej txheem tsim cov tshuaj sib txuas ntawm cov polyethylene molecules, hloov cov khoom mus rau hauv "semi-thermoset" polymer uas muab kev ruaj ntseg ntev ntev -. Qhov kev hloov pauv no ua kom PEX coj cov kev ua haujlwm tseem ceeb ntxiv nrog rau qhov kub siab zog, yoog raws, tshuaj tsis haum, toughness, thiab abrasion tsis kam. Txhua hom PEX tubing yog qhov zoo ib yam, txhais tau tias yog tooj liab tube loj (CTS), thiab yuav tsum ua tau raws li cov qauv kev ua haujlwm nruj, uas suav nrog ASTM F876. Kev nkag siab txog qhov sib txawv pab koj xaiv cov khoom tsim nyog rau cov ntawv thov tshwj xeeb-tshwj xeeb tshaj yog thaum nws los txog rau kev tiv thaiv khov thiab kev txhim kho yooj yim.

PEX-A: Peroxide Method thiab Siab Flexibility

PEX-A yog tsim los siv txoj kev peroxide, tseem hu ua Engel method. Hauv cov txheej txheem no, cov organic peroxides ntxiv rau cov khoom siv raw polyethylene, thiab thaum tshav kub kub, lawv tsim cov dawb radicals reactive uas splice polymer chains ua ke raws li cov yeeb nkab extruded. Txoj kev no ua rau qhov hloov tau yooj yim tshaj plaws ntawm txhua hom PEX, nrog tus ntoo khaub lig siab tshaj - txuas qhov ceev mus txog 85%. PEX-A muaj qhov tseem ceeb tsis muaj lub cim xeeb coil, txhais tau tias nws nyob qhov twg koj khoov nws yam tsis muaj qhov rov qab, ua rau nws zoo tagnrho rau kev taug kev nruj qhov chaw thiab kev teeb tsa nyuaj.

Rau cov neeg yuav khoom nrhiav pliability, qhov no yog qhov kev xaiv saum toj kawg nkaus. Qhov txiaj ntsig tseem ceeb tshaj plaws ntawm PEX-A yog nws lub peev xwm tshwj xeeb los kho yog tias kinked. Yog tias PEX-Ib lub yeeb nkab tau txais kev nruj nruj, koj tuaj yeem siv cov cua sov los ntawm rab phom kub kom rov qab tau nws cov duab yam tsis muaj kev cuam tshuam cov yeeb nkab ncaj ncees. PEX-A kuj yog tib hom sib xws nrog cov khoom siv txias txias, txoj kev sib txuas ruaj ntseg peb yuav npog tom qab hauv cov koob no.

PEX-B: Silane Method thiab Market Dominance

PEX-B sawv cev rau hom PEX yeeb nkab ntau tshaj plaws nyob rau hauv kev ua lag luam niaj hnub no thiab yog tsim los siv cov silane, los yog kev kho dej noo, txoj kev. Txoj kev no tsis tshua kim, ua rau muaj peev nyiaj ntau dua - cov yeeb nkab zoo. Cov txheej txheem no suav nrog grafting ib reactive silane molecule rau lub caj qaum ntawm polyethylene, tso cai rau cov yeeb nkab hla -txuas tom qab extrusion thaum raug rau ya raws thiab cua sov, xws li chav kho. PEX-B muaj lub siab tawv dua piv rau PEX-A, nrog tus ntoo khaub lig- txuas qhov ceev feem ntau ntawm 65% thiab 70%.

Rau pob nyiaj siv -cov neeg yuav khoom, PEX-B muab tus nqi zoo tshaj plaws - rau - qhov ua tau zoo piv. Cov xwm txheej nruj ua rau qee lub cim xeeb coil, txhais tau tias cov yeeb nkab yuav sim rov qab mus rau nws qhov qub coiled zoo li qub, uas tuaj yeem ua rau kev teeb tsa nyuaj dua hauv qhov chaw nruj tsis muaj kev ruaj ntseg txaus. Txawm li cas los xij, nws yog qhov ruaj khov thiab sib haum nrog txhua yam ntawm cov khoom siv kho tshuab, suav nrog kev sib txuas ntawm crimp thiab clamp, ua rau nws muaj ntau yam thiab dav xaiv rau cov txheej txheem dej haus.

PEX-C: Electron Beam Method thiab Uniform Cross-Txuas

PEX-C yog tsim los siv cov txheej txheem hluav taws xob irradiation, feem ntau hu ua txias lossis electron beam txoj kev hla- txuas. Nyob rau hauv txoj kev no, lub siab - lub zog hluav taws xob hluav taws xob yog siv rau HDPE yeeb nkab tom qab nws tau extruded, tsim cross- txuas ntawm qib molecular yam tsis siv cov tshuaj catalysts. Qhov no ua rau cov yeeb nkab nrog tus ntoo khaub lig- txuas qhov ceev ntawm 70% mus rau 75%, muab nws nruab nrab ntawm PEX-A thiab PEX-B raws li qhov yooj yim.

Hom no yog lub npe hu rau nws cov ntoo khaub lig sib xws -txuas kev sib txuas, raws li cov kab hluav taws xob tuaj yeem raug tswj xyuas kom ntseeg tau tias muaj kev sib faib sib txuas thoob plaws hauv cov yeeb nkab phab ntsa. PEX-C muaj kev tiv thaiv zoo rau cov tshuaj chlorine thiab UV hluav taws xob, pab tswj kev ua haujlwm hauv cov dej nyuaj. Txawm li cas los xij, vim tias nws tsis muaj cov khoom siv ntxiv uas siv hauv Engel lossis silane txoj kev, qee zaum nws tuaj yeem hloov pauv tsawg dua hauv cov xwm txheej khov. Rau cov txheej txheem dej kub thiab dej txias, PEX-C ua haujlwm tau zoo, tab sis cov kws tshaj lij feem ntau xaiv nws rau cov haujlwm uas qhov kev taug qab thiab kev sib raug zoo yog qhov tseem ceeb, xws li hauv cov tsev nyob hauv ntau tsev neeg.

Kev Ntsuas Kev Ua Haujlwm: ASTM Cov Qauv thiab Kev Ntsuas Siab

Txawm hais tias koj xaiv hom A, B, lossis C, cov yeeb nkab yuav tsum dhau cov qauv kev lag luam tib yam. Cov kev ntsuam xyuas hydrostatic siab zoo sib xws hauv txhua hom. Rau SDR 9 PEX tubing, tus qauv ntsuas yog 160 psi ntawm 73℃F (1105 kPa ntawm 23 degree) thiab 100 psi ntawm 180℃F (690 kPa ntawm 82 degree). Cov xim sib txawv ntawm cov hom yog feem ntau siv thaum lub sij hawm installation: xiav rau cov dej txias, liab rau cov dej kub, thiab dawb rau kev sib tov.

Cov neeg tsim khoom kuj tseem muab Cov Cai Tsim Khoom Siv, uas yog plaub tus lej - tus lej uas pab qhia cov yam ntxwv ua haujlwm. Thawj tus lej hais txog cov tshuaj chlorine tsis kam-nrog Chav Kawm 5 yog qhov ntsuas siab tshaj plaws -thaum ob tus lej kawg, feem ntau "06," qhia qhov ntsuas siab ntawm 160 psi ntawm 73℃F .

Ua Qhov Kev Xaiv Zoo rau Koj Daim Ntawv Thov

Koj qhov kev xaiv yuav ua raws li koj daim ntawv thov tshwj xeeb, pob nyiaj siv, thiab kev teeb tsa ib puag ncig ntau dua li ntawm ib hom yog universally "zoo dua" dua lwm qhov. Rau tej yaam num xws li radiant pem teb cua sov qhov twg heev yooj yuav tsum tau khoov tubing nyob ib ncig ntawm obstacles, PEX-A yog tus qauv kev lag luam. Rau cov txheej txheem kev tsim kho vaj tsev nyob qhov twg cov peev nyiaj yog tus tsav tsheb tseem ceeb thiab kev teeb tsa ncaj qha, PEX-B yuav muab kev pabcuam txhim khu kev qha. Rau siab -purity daim ntawv thov uas yuav tsum tau muaj cov tshuaj sib xws ntawm tus ntoo khaub lig- txuas yam tsis muaj cov catalysts seem, PEX-C tej zaum yuav yog qhov tshwj xeeb ntawm kev xaiv. Nco ntsoov xyuas kom cov yeeb nkab koj xaiv nqa cov ntawv pov thawj tsim nyog rau cov dej haus, xws li NSF / ANSI 61, thiab tau pom zoo rau koj daim ntawv thov tshwj xeeb, txawm tias nws yog cov kav dej lossis cov cua sov hydronic.

Cov ntsiab lus

PEX yeeb nkab hom A, B, thiab C qhia txog kev tsim khoom-peroxide, silane, lossis electron beam- tsis yog qib zoo. PEX-Ib qho yooj yim tshaj plaws thiab muaj peev xwm kho kink; PEX-B yog qhov ntau tshaj thiab tus nqi- zoo; PEX-C muab kev sib koom ua ke hla- txuas. Txhua hom ua tau raws li cov qauv kev ua tau zoo ASTM nrog SDR-9 qhov ntsuas siab ntawm 160 psi ntawm 73℃F thiab 100 psi ntawm 180℃F. Kev xaiv yuav tsum yog raws li cov kev xav tau ntawm daim ntawv thov, kev txwv kev teeb tsa, thiab kev siv nyiaj ntau dua li qhov xav tias ib hom yog universally superior rau tag nrho cov kav dej.
