Cov hom thiab cov yam ntxwv ntawm cov raj yas uas siv ntau rau kev ntim khoom kom zoo nkauj

2025-11-06

Cov haujlwm thiab lub luag haujlwm ntawm cov tshuaj pleev ib ce tau dhau los ua qhov ntxaws ntxaws ntxiv, thiab muaj ntau thiab ntau cov tshuaj pleev ib ce nrog cov haujlwm tiav. Qhov sib txawv ntawm cov qib yog qhov tseem ceeb heev, thiab cov ntawv ntim khoom zoo nkauj heev.

Cov raj yas rau cov khoom ntim khoom kom zoo nkauj

Tam sim no, cov raj yas uas siv ntau rau kev ntim khoom kom zoo nkauj feem ntau yog tsim los ntawm cov raj txhuas-yas sib xyaw, cov raj rub-yas sib xyaw thiab cov raj yas sib xyaw, uas tuaj yeem ua tau raws li ntau yam kev xav tau ntawm kev ntim khoom kom zoo nkauj xws li kev huv thiab kev tiv taus.

1. Lub raj yas sib xyaw ua ke

Cov raj yas sib xyaw ua ke uas yooj ywm yog ua los ntawm cov ntawv ci txhuas thiab cov yas zaj duab xis, uas raug ua tiav rau hauv cov phaj los ntawm kev siv tshuab pneumatic lamination thiab tom qab ntawd ua tiav rau hauv cov thawv ntim khoom tubular los ntawm cov tshuab raj tshwj xeeb. Cov qauv ib txwm muaj yog PE / PE EAA / AL / PE EAA / PE. Cov raj yas sib xyaw ua ke uas yooj ywm yog siv rau kev ntim cov tshuaj pleev ib ce uas muaj kev huv huv thiab cov khoom thaiv. Cov txheej thaiv feem ntau yog cov ntawv ci txhuas, thiab nws cov khoom thaiv nyob ntawm qhov degree pinhole ntawm cov ntawv ci txhuas.

Cov yeeb nkab ua los ntawm txhuas-yas muaj cov txiaj ntsig zoo li nram no thaum siv:

Cov khoom thaiv siab: Cov ntawv ci txhuas muaj cov khoom thaiv, tiv thaiv hluav taws xob, tiv thaiv dej thiab lwm yam kev thaiv, tiv thaiv cov khoom sab nraud kom tsis txhob nkag mus rau hauv cov tshuaj pleev ib ce, zam kev oxidation thiab kev puas tsuaj ntawm cov tshuaj pleev ib ce, thiab tiv thaiv cov dej noo lossis cov tshuaj tsw qab thiab lwm yam khoom hauv cov tshuaj pleev ib ce kom tsis txhob tawg mus rau sab nraud los ntawm lub raj, yog li ua kom ntseeg tau tias cov tshuaj pleev ib ce zoo.
Tus nqi qis. Yuav kom ua tiav tib lub luag haujlwm thaiv, cov yeeb nkab sib xyaw ua los ntawm txhuas-yas muab cov khoom siv tsawg dua, tus nqi qis dua thiab kev lag luam tsawg dua li cov yeeb nkab sib xyaw ua los ntawm yas thiab cov yeeb nkab sib xyaw ua ke.

2. Cov yeeb nkab yas sib xyaw ua ke

Cov yeeb nkab yas sib xyaw ua ke yog ua los ntawm yas thiab muab faib ua cov yeeb nkab yas tsis thaiv thiab cov yeeb nkab yas tiv taus. Cov qauv ib txwm muaj ntawm cov yeeb nkab yas thaiv yog PE/PE/EVOH/PE/PE.

Cov txiaj ntsig ntawm cov yeeb nkab yas sib xyaw suav nrog: (1) Kev tiv thaiv ib puag ncig. Piv nrog cov yeeb nkab txhuas-yas sib xyaw, cov yeeb nkab yas sib xyaw siv cov laug cam yas pheej yig thiab yooj yim rov ua dua tshiab, txo cov pa phem ntawm cov khoom ntim khoom pov tseg rau ib puag ncig. Tom qab rov ua dua cov yeeb nkab yas sib xyaw rov ua dua tshiab, cov khoom lag luam qis dua tuaj yeem tsim tau.

Nws muaj ntau yam xim. Raws li cov yam ntxwv ntawm cov tshuaj pleev ib ce thiab cov neeg siv khoom xav tau, cov raj yas sib xyaw ua ke yog ua los ntawm ntau yam xim xws li tsis muaj xim thiab pob tshab, xim thiab pob tshab, thiab tsis muaj xim thiab tsis pom tseeb, uas tuaj yeem coj cov neeg siv khoom kom pom kev zoo.
Kev ua kom muaj zog zoo: Piv nrog cov yeeb nkab ua los ntawm txhuas-yas sib xyaw, cov yeeb nkab yas sib xyaw muaj kev ywj pheej zoo dua. Tom qab rho cov tshuaj pleev ib ce tawm, cov yeeb nkab rov qab mus rau nws cov duab qub sai sai thiab ib txwm khaws cia cov duab zoo nkauj thiab ib txwm. Qhov no tseem ceeb heev rau kev ntim khoom pleev ib ce.

Cov txiaj ntsig tseem ceeb ntawm cov yas co-extruded hoses suav nrog: (1) Tsis muaj kev hloov pauv amplitude, thiab nws cov tsos zoo dua li ntawm cov composite hoses. Nws yog qhov yuav tsum tau rau cov khoom siv kho kom zoo nkauj siab kawg. (2) Raws li lub extrusion tuag, ntau yam duab ntawm extruded hoses (xws li oval, square, thiab lwm yam) tuaj yeem tsim los ua kom tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv.
