Tsis ntev los no, kev siv cov kav dej yas rau cov kav dej, kav dej lossis cua sov tau suav tias yog qhov tshiab, tab sis niaj hnub no lawv tau pom cov ntawv thov dav. Cov kav dej polyethylene, cov yam ntxwv ntawm kev sib txawv ntawm cov hlau, qee zaum ua haujlwm rau lawv cov tswv rau ntau tshaj 50 xyoo. Yog li lawv qhov tshwj xeeb yog dab tsi?
Txheej txheem cej luam ntawm cov kav dej polyethylene
thawj thiab qhov tseem ceeb ntawm cov yeeb nkab no yog nws qhov kev tiv thaiv corrosion. Nws ua tsaug rau nws tias lawv tuaj yeem tiv taus lub sijhawm ntev ntev yam tsis tau kho. Tsis tas li ntawd, cov kav dej polyethylene rau cov kav dej thiab cov kav dej phwj tuaj tsis raug rau electrochemical corrosion. Lawv sab hauv yog du, uas tso cai rau kom nce lub throughput. Txawm tias tom qab ntau xyoo ntawm kev ua haujlwm, cov kav dej polyethylene rau cov kav dej, cua sov lossis cov kav dej phwj tuaj muaj qhov zoo dua li cov hlau, vim tias tsis muaj cov kav dej.deposits nyob. Cov khoom zoo tuaj yeem tsim tsis tau tsuas yog los ntawm yas, tab sis kuj los ntawm hlau. Tsis tas li ntawd, condensation tsis tuaj yeem tsim rau ntawm lawv qhov chaw. Cov txiaj ntsig zoo no tau ua rau cov kav dej polyethylene (lawv cov yam ntxwv ntawm cov txheej txheem yuav tau piav qhia hauv qab no) yog li nrov.
yam ntxwv ntawm cov kav dej polyethylene
Yog tias peb xav txog cov kav dej polyethylene (cov txheej txheem tshwj xeeb) rau cov kav dej, kav dej lossis cua sov, ces ua ntej koj yuav tsum tau xyuam xim rau cov khoom siv hauv cov khoom siv hauv lawv cov muaj pes tsawg leeg, ces peb tuaj yeem tham txog qhov tsis kam ntawm cov yeeb nkab. kom siab los ntawm sab hauv thiab txoj kab uas hla ntawm cov khoom. Yog li ntawd, yog tias koj xav paub ntau ntxiv txog cov kav dej polyethylene yog dab tsi, los kawm txog lawv cov yam ntxwv thiab cov yam ntxwv, koj yuav tsum xub paub koj tus kheej nrog cov npe ntawm polyethylene yog dab tsi:
- PE 63 (tam sim no tsis siv tau).
- PE 80 - muaj cov khoom zoo thiab tuaj yeem tiv taus lub siab loj ntawm cov kua dej. Hom no yog siv los tsim cov kav dej me me, uas tau muab tso rau hauv dej.
- PE 100 - siv los tsim cov kav dej nrog txoj kab uas loj, uas yog siv rau hauv kev tsim kho txoj kev loj nrog dej txias.
Txoj kab uas hla, uas tseem suav nrog cov yam ntxwv ntawm cov kav dej polyethylene, tuaj yeem sib txawv kiag li. Qhov ntau yog los ntawm 20 hli mus rau 120 cm. Lawv qhov ntev feem ntau nyob ntawm seb lawv txoj kab uas hla. Yog li, piv txwv li, ib txoj kab uas hla ntawm 20 mus rau 110 mm qhia tias nws qhov ntev tsis yogyuav tshaj 50 meters.
Qhov zoo ntawm txoj kab dav dav polyethylene kav
Tsis ntev los no, nws yog cov kav dej uas muaj txoj kab uas hla loj uas xav tau ntau tshaj plaws. Qhov no tuaj yeem piav qhia los ntawm qhov tseeb tias lawv tau siv rau kev tsim kho ntawm cov khoom siv hluav taws xob, cov kav dej, cov kav dej los yog cov kav dej. Lawv muaj ob peb yam tseem ceeb ntawm cov qauv hlau:
- Kev tsim khoom, kev teeb tsa thiab kev ua haujlwm yog pheej yig dua li hlau.
- Yog dej hauv khov, yuav tsis muaj dab tsi phem.
- Qhov hnyav ntawm cov yeeb nkab yog qis dua, yog li kev thauj mus los thiab kev teeb tsa yooj yim dua.
- Technical polyethylene yeeb nkab muaj kev nyab xeeb thiab tsis muaj tshuaj lom.
- Tsis txhob txhawj txog kev xa khoom vim lawv tsis yog cov khoom txaus ntshai.
- Shock thiab stretch resistant. Kev sib txuas yog txhim khu kev qha thiab ruaj khov, uas ua rau kom lub neej ntawm cov yeeb nkab.
YPolyethylene kav dej
Ua tsaug rau polyethylene, cov kav dej phwj tuaj tau txais qhov zoo tshiab, thiab nws qhov zoo tau zoo dua qub. Qhov tseeb yog tias polyethylene pab txhim kho txoj kev loj hlob ntawm nws tus kheej, thiab nws cov kev tsim kho yog ntau zaus thiab sai dua. Piv txwv li, koj tuaj yeem siv lub npe hu ua trenchless nteg. Cov kav dej polyethylene, cov yam ntxwv ntawm kev ua haujlwm uas pab kom tsis txhob cuam tshuamtxawm tias cov tshuaj muaj zog tuaj yeem thauj tau yooj yim thiab sib sau ua ke. Lawv txoj kev sib txuas yog suav tias muaj zog thiab txhim khu kev qha, uas pab tiv thaiv kev sib tsoo.
corrugated polyethylene kav
Cov kav dej no rau cov kav dej thiab cov kav dej yog tsim los ntawm ob txheej polyethylene tshwj xeeb. Raws li txoj cai, lawv siv PE 80 hom, uas yog qhov haum tshaj plaws rau cov qauv no ntawm txoj kab uas hla. Cov kav dej tiv taus cov tshuaj. Vim yog lub nplhaib tshwj xeeb nruj, uas yog siab heev, corrugated polyethylene kav tuaj yeem ntsia tau siv txoj hauv kev zais ntawm qhov tob ntawm ib mus rau nees nkaum meters. Muaj cov kav dej corrugated ua los ntawm polyethylene thiab rau qhov hu ua cov dej phwj tuaj sab nraud.
Cov kav dej rau cov kav dej phwj thiab dej
Qib ntawm polyethylene 80 yog qhov ruaj khov tshaj plaws ntawm txhua tus paub niaj hnub no. Tias yog vim li cas nws thiaj li siv los tsim cov kav dej polyethylene tshwj xeeb uas tuaj yeem tiv taus ob qho tib si siab thiab qis. Lawv tuaj yeem siv tau yam tsis muaj teeb meem txawm tias nyob hauv ib puag ncig hnyav heev, tab sis thaj chaw tseem ceeb ntawm daim ntawv thov tseem yog dej. Lawv tsis haum rau cov kav dej phwj tuaj. Cov kab uas nrov tshaj plaws ntawm cov kav dej niaj hnub no yog los ntawm 2 txog 6.3 cm.
Ntaus polyethylene yeeb nkab manufacturers
Hauv khw muag khoom niaj hnub no, los ntawm ntau yam thiab ntau yam ntawm cov kav dej polyethylene, qhov muag tsuas yogtawg tawg. Yog tias koj tsis paub cov kav dej twg yog qhov zoo tshaj plaws los yuav, koj yuav tsum xub nrhiav seb leej twg ua cov qauv no.
Lub tuam txhab nrov tshaj plaws rau kev tsim cov kav dej polyethylene rau cov kav dej thiab dej niaj hnub no yog Rehau. Nws tsim cov khoom zoo thiab cov khoom siv ruaj khov uas tsim nyog rau cov kav dej thiab cov kav dej ntawm txhua qhov nyuaj thiab ntev. Tsis tas li ntawd, cov yeeb nkab dej polyethylene, uas nws cov yam ntxwv ntawm kev hais txog nws qhov zoo, yog yooj yim rau kev sib sau ua ke, yooj yim rau kev thauj mus los thiab teeb rau nws tus kheej.
Lub tuam txhab Wavin los ntawm Netherlands tsim cov kav dej polyethylene rau cov kav dej. Los ntawm kev xaiv lub tuam txhab no, koj yuav tsis nco qab ntev npaum li cas kho. Lub ntsiab feature ntawm Wavin polyethylene kav yog tias lawv muaj suab nrov-insulating zog thiab tiv taus kub (txog 90 degrees).
Lavxias teb sab manufacturers kuj tsis lag tom qab cov neeg txawv teb chaws thiab tsim cov kav dej los ntawm cov khoom siv zoo polyethylene ntawm qhov hu ua low pressure. Cov qauv zoo li no yog tus cwj pwm los ntawm tus nqi qis tshaj, yog li lawv nrov heev nrog cov neeg tsim khoom thiab cov neeg yuav khoom.
