Tau pib los nruab ib lub tsev sov sov, cov lus nug tshwm sim uas cov khoom siv yeeb nkab uas tau zoo dua: stitched polyethylene lossis yas.
Cov lus teb nyob rau hauv cov xwm txheej ntawm kev ua haujlwm sov, thiab cov kev xav ntawm cov kws tshaj lij, kev paub thiab tshuaj xyuas ntawm cov neeg ua haujlwm cua sov hauv pem teb yuav pab daws cov teeb meem no.
Raws li yuav luag txhua cov kav dej tshiab, stitched polyethylene lus dag, tsuas yog cov txheej txheem hlau-yas ntxiv cov txheej txheem nplaum uas ua kom cov monolith ntawm cov khoom.
Stitched Polyethylene: Cov Khoom Siv
Vim muaj cov qauv molecular ntawm stitched polyethylene kav muaj lub zog siab
Stitched Polyethylene yog hais txog cov khoom siv high-tech thiab yog tsim cov polymerization ntawm ethylene muaj molecular qauv nrog cov tsiaj ntawv luv.
Conditionality, tus txheej txheem stitching yog los tsim cov kev sib txuas ntxiv molecular. Pib pib polymer yog txuam nrog kev chimt rau ntawm qib molecules, sib sau ib qho kev sib tw sab dawb, ib qho qauv muaj zog tshwj xeeb nrog lub cim xeeb ".
Ib Leeg Txheej Khoom yog qhov zoo dua
Kev hloov pauv ntawm qhov loj thiab cov duab ntawm cov yeeb nkab hauv qab cov ntawm cov khoom thauj tom qab lawv tshem tawm cov khoom lag luam rov qab cov khoom lag luam hauv daim ntawv qub. Raws li cov khoom siv txuj ci, REX tsis yog qis dua rau ntau cov khib nyiab thiab ntau tshaj nyob rau hauv lub neej pabcuam.
Stitched polyethylene kav dej ua 4 txoj kev:
- Lub Peroxide tau qhia rau hauv polyethylene hauv kev tsim cov khoom siv. Qib siab tshaj plaws ntawm crosslinking yog 75%. Nyob rau hauv txoj kev ntawm cov khoom lag luam qis thiab siab ntawm cov khoom, tab sis cov khoom siv ua ruaj khov thiab ywj.
- Rov -hb - kev ua haujlwm ntawm noo noo nrog cov silane thiab catalyst tsim polyethylene, los ntawm lub plhaub ntawm cov khoom lag luam, tab sis thaum cov kua dej siab. Stitching yog 65%.
- RECH - C - POLYMER kho nrog electrons. Polyethylene nrog tsawg degree ntawm crosslinking 55 - 60%.
- RH - xD - nitric acid yog siv. Tus txheej txheem yog tsis tshua thov.
Ntawm cov txheej txheem teev, cov yeeb nkab ua nrog kev siv cov kab xev yog feem ntau hauv kev thov, yog cim los ntawm cov khoom ua haujlwm zoo thiab lees paub.
Tshooj ntawm cov ncauj lus: npaj ntawm cov txiv qaub-raws plaster
Qhov zoo tshaj plaws ntawm cov yeeb nkab rau lub tsev sov ntawm cross-txuas cov polyethylene yog ib qho kev thaiv kev rov ua dua, uas yog ib qho kev sib cais rau polyethylene puas tsuaj.
Cov txiaj ntsig ntawm stitched polyethylene khoom
Cov yeeb nkab los ntawm xws li cov khoom siv muaj molecular nco
Cov kav dej ntawm cua sov tsim los ntawm cov txheej txheem ntawm re-ha thiab re - XB yog tus yam ntxwv:
- Tsis kam rau lub siab poob. Nyob rau hauv hom siab siab, lub neej ntawm cov khoom tsis hloov. Lub polymer yog qhov tseem ceeb txog 10 atmospheres.
- Molecular nco. Thaum cov dej khov rau hauv cov yeeb nkab, cov dej khov ua rau txoj kab uas hla ntawm cov dej khov, thiab tom qab cov yeeb nkab rov qab los rau tus thawj version, yam tsis muaj kev ua kom cov khoom siv.
- Melting thiab hlawv ntawm qhov kub siab. Cov ntaub ntawv los melting ntawm ib tug kub ntawm ntau tshaj 150 ° C, thiab ignition thaum lub ambient kub nce mus txog 400 ° C.
- Kev tawm tsam tshuaj thiab txheeb raws roj ntsha. Cov leeg polyethylene tsis raug rau cov txheej txheem ntawm corrosion, tsis tsim cov kev mob rau cov kab mob fungi thiab tseem nyob rau chlorine thiab tseem nyob rau chlorinated dej.
- Kev nyab xeeb ib puag ncig. Cov khoom siv thaum lub sijhawm cua tsis zais cov teeb meem thiab decomposes ntawm cov pa roj carbon dioxide thiab dej thaum hlawv.
Polyethylene tsis ntshai ntawm qhov kub
- Yas. Nrog kev tshaj tawm, cov khoom lag luam tsis tawg thiab kho qhov loj me ntawm khoov.
- Ua haujlwm. Cov khoom siv polymer khaws cov khoom, tseem tsis tau hloov pauv cov yeeb nkab uas muaj qhov txias ntawm 0 txog 95 ° C, tab sis cov khoom siv muaj peev xwm tiv taus thiab ntau qhov kub.
Hlau Yas Tube: Khoom
Qhov zoo ntawm tus ntoo khaub lig txuas nrog Polyethylene tseem muaj lub raj hlau-yas muaj tsib txheej, txhua yam uas ua qee yam haujlwm. Lub sab nraud thiab sab hauv polymeric, thiab cov plhaub sab nraud Polyethylene, thiab cov txheej txheem sab hauv cov kua dej.
Lub puab txheej du tsis ua cov teeb meem rau dej tam sim no
Muaj 2 cov khaubncaws sab nraud povtseg ntawm cov khaubncaws sab nraud povtseg ntawm cov txheej polymer, thiab hauv txheej sab hauv yog cov xim hlau uas muab cov qauv ntawm cov khoom lag luam hlau-yas.
Kev ntseeg tau thiab tsis txaus ntseeg hauv kev ua haujlwm ntawm cov hlau-cov khoom lag luam txiav txim siab qhov zoo ntawm cov khaubncaws sab nraud pov hwm:
- Cov txheej txheem aluminium ntawm cov khoom txiav txim siab nws lub zog thiab yuav tsum yog tuab ntawm tsawg kawg yog 3 hli. 2 Txoj kev ntawm vuam ntawm txhuas txheej cuam tshuam rau lub zog ntawm cov yeeb nkab, laser vuam hauv cov pob qij txha thiab ultrasonic vuam ntawm tooj dag yog cov thev naus laus zis siv. Cov txheej txheem ntawm vuam ib txheej ntawm jack yog hu ua seamless, nws tsis muaj qhov tsis muaj kev sib tw thiab hauv kev sib piv nrog cov dej sib txuas nrog cov fittings.
- Cov nplaum siv txiav txim siab cov txheej txheem ntawm cov khaubncaws sab nraud ntawm cov txheej txheem ntawm kev hloov pauv kub ntawm lub txias, uas cuam tshuam rau lub zog ntawm cov yeeb nkab. Ntawm qhov txiav tej yeeb nkab thaum siv cov kua nplaum zoo, cov pob khoom ploj lawm.
- Kev ntseeg tau ntawm cov yeeb nkab yog txiav txim siab los ntawm txheej ntawm cov kab polymer, thiab cov kav dej nrog lwm lub hnab ntim, thiab cov kav dej nrog rau lwm qhov cim npe, hauv qhov kev sib txuas ntawd, nrog ib tug txiv neej hydraulic.
Thaum xaiv lub tshuab hlau nplaum hlau-yas, peb xav tias cov khoom no muaj cov txheej txheem sib txuas, muab cov teeb meem kev ua haujlwm tsis zoo ntawm cov khoom.
Kev xaiv cov kav dej rau cov dej pem teb
Sim xaiv cov ntaub ntawv zoo
Proposals ntau thiab txog cov khoom, thiab txog cov chaw tsim khoom yog ib qho, qhov kev xaiv ntawm tus nqi / zoo, tab sis nws yog qhov tsim nyog los pib nrog zoo:
- Cov yeeb nkab kev ntseeg tau thiab cov neeg kho tshuab zog thaum siv rau hauv cov xwm txheej tshwj xeeb, uas yuav ua kom muaj teeb meem tshwj xeeb ntawm kev ua haujlwm ntawm lub sijhawm thaum lub sijhawm ua haujlwm, i.e. Cov yeeb nkab yuav tsum tau tiv thaiv qhov siab ntawm tsawg kawg 10 bar.
- Qhov kev pabcuam lub neej lossis ruaj khov ntawm kev siv lub hauv paus sov pem teb yog nyob ntawm cov khoom uas cov khoom yog tsim. Kev deformation ntawm cov yeeb nkab tsis tso cai ntawm qhov kub ntawm lub txias 95 ° C.
- Txhawm rau pub dawb txav los ntawm cov kav dej ntawm lub coolant, sab hauv ntawm cov yeeb nkab yuav tsum yog.
- Cov xwm txheej rau kev saib xyuas, cov nqi tiv thaiv kev ua haujlwm thiab kev tswj hwm ntawm cov kab ke kom nruj. Nyeem ntxiv txog cov kav dej yuav xaiv, saib hauv daim vis dis aus no:
Cov yam ntxwv sib piv ntawm cov khoom cua sov muaj los ntawm kev ua lag luam, qhov nyuaj ntawm kev teeb tsa ua haujlwm thiab kev ua haujlwm tau txiav txim siab tom qab ntsuas cov yam ntxwv zoo. Thaum kawg tab sis, peb piv cov nqi ntawm cov khoom lag luam, noj rau hauv kev ua haujlwm ntawm tus account, nrog rau kev nyuaj nrog kev kub siab pem teb.
Kev sib piv ntawm cov kav dej ntawm cov kav dej nrog txoj kab uas hla ntawm 20 hli

Hlau yas yog tsawg dua cov yas sib piv rau cov polyethylene
Txhua qhov zoo ib yam, dab tsi cov yeeb nkab zoo dua rau lub hauv pem teb sov: polyethylene lossis hlau. Qhov sib txawv ntawm cov khoom hauv cov khaubncaws sab nraud ntawm cov kab ntoo khaub lig polyethylene ntawm cov hlau yas yeeb thiab cov hlau txheej.
Txhim kho cov polymer, cov kws tshawb fawb thiab cov kws tshaj lij hauv kev kho lub npe ntawm PE - RT, nyob rau hauv uas cov qauv molecular nrog kev sib raug zoo. Cov polymer tsis poob nws cov khoom hauv kev rov ua dua tshiab, tsis zoo li ua ntej ua ntej. Cov lus pom zoo ntawm cov kws tshaj lij hauv kev xaiv cov kav dej pom hauv cov yeeb yaj kiab no:
Cov kav dej los ntawm PE - RT polyethylene nrog lub taub hau muaj zog ntawm lub txias txias cais tawm cov suab nrov ntawm cov kua dej ntws. Lub polymer tseem ceeb tshaj qhov dhau los polyethylene kuj mus rau kev kub siab thiab ntsuas kub ntawm lub caij txias, nrog rau lub sijhawm ntawm cov raj xa dej.
Ua tsaug rau cov qauv molecular nrog cov qauv sib txuas, PE cov cuab yeej khaws cia cov thermoplastic, kav dej yam tsis muaj kev puas tsuaj rau thaj chaw uas puas lawm.
Cov khoom siv nrog ntau ntau lub voj voog thiab cov neeg sib cav sib ceg tsis hloov pauv cov qauv thiab cov khoom. PE-RT cov khoom tsim ob cov khoom polymeric thiab yas yas.
Lub tshav kub-resistant PE - RT polymer nyob rau hauv nws cov khoom kom tau raws li cov kev xav tau ntawm chav sov thiab tuaj yeem suav tau tias yog qhov kev xaiv zoo tshaj plaws thaum xaiv cov kav dej.
