Qhov twg yog qhov ua tau zoo dua
Ob lub raj PTFE thiab PU raj siv dav hauv ntau yam lag luam, tab sis qhov chaw siv ntawm ob qho tsis zoo ib yam. Lub raj PTFE siv rau hauv qhov chaw ua haujlwm hnyav dua, thiab qhov loj me kuj tiav lawm, cov lag luam siv tau dav dua li lub raj PU. Lub raj PU tsim nyog rau kev ua haujlwm hauv qab qhov siab thiab kub ib txwm muaj. Vim tias nws cov khoom siv yog mos thiab ywj, nws tuaj yeem khoov tau raws li qhov xav tau. Nws tsim nyog dua rau qhov chaw nqaim lossis ib puag ncig nrog lub vojvoog khoov siab.
Cov hauv qab no yog cov lus qhia ntxaws txog ob hom raj:
PTFE raj:
Ptfe yeeb nkab yog ib lub yeeb nkab tshwj xeeb ua los ntawm PTFE cov khoom tom qab extrusion thiab sintering, ziab, kub sintering, thiab shaping. Polytetrafluoroethylene (PTFE) muaj kev ruaj khov tshuaj zoo heev, xws li:
1. Tiv taus kub thiab siab. Nws siv tau ntev ntawm -65 ℃ ~ 250 ℃ hauv qab qhov siab ib txwm. Tom qab 1000 teev ntawm kev kho kub siab ntawm 250 ℃, nws cov khoom siv kho tshuab yuav tsis hloov pauv ntau.
2. Tiv thaiv xeb thiab tiv thaiv kev laus, tuaj yeem tiv taus txhua yam kua qaub muaj zog, alkalis muaj zog, cov tshuaj oxidants muaj zog, thiab yuav tsis cuam tshuam nrog ntau yam organic solvents.
3. Kev rwb thaiv tsev. Vim tias PTFE tsis muaj polarity, tiv taus cua sov thiab tsis nqus dej, nws kuj yog cov khoom siv rwb thaiv tsev zoo heev.
4. Kev sib txhuam tsawg. PTFE muaj kev sib txhuam tsawg heev. Nws yog ib yam khoom zoo uas tiv thaiv kev sib txhuam thiab ua rau nws tus kheej lubricating. Nws cov kev sib txhuam zoo li qub tsawg dua li cov kev sib txhuam dynamic. Yog li ntawd, nws muaj qhov zoo ntawm kev pib tsis kam thiab kev khiav du thaum siv los ua cov bearings.
5. Tsis kub hnyiab, tsis muaj tshuaj lom, lub teeb, yooj ywm zoo thiab lwm yam ntxwv, ntau yam kev siv, tsis yooj yim rau kev puas tsuaj, lub neej ua haujlwm ntev, tsis tas yuav hloov pauv ntau zaus yog qhov tseem ceeb tshaj plaws
Lub hom phiaj ntawm PU yeeb nkab:
Nws yog dav siv hauv tsheb, aerospace, hydraulics, pneumatics, railways, zaub mov ua, kua khoom siv thauj mus los, tshuaj lom neeg thauj mus los, kev tsim khoom thiab petrochemical, hluav taws xob khoom insulators, thiab lwm yam.
Polyurethane hose:
Cov raj polyurethane yog cov raj PU, muab faib ua cov raj tawv thiab cov raj dej, cov raj pob tshab, thiab lwm yam. Lub ntsiab lus tseem ceeb yog tias cov raj mos thiab tuaj yeem tau txais qhov me tshaj plaws ntawm qhov nkhaus. Vim nws lub teeb thiab mos, nws yooj yim thiab yoog tau siv. Cov raj PU feem ntau yog siv rau cov kav dej cua, cov kav dej thiab cov kav dej thauj khoom nrog lub siab ua haujlwm ib txwm thiab kub. Tab sis piv rau cov kav dej PTFE, cov kav dej PU yooj yim dua rau kev laus thiab hydrolysis thiab muaj lub neej ua haujlwm luv dua. Kev ruaj khov tshuaj lom neeg tsis zoo, xws li:
1. Qhov kub ua haujlwm yog nruab nrab ntawm -20 ° thiab + 60 °;
2. Qhov kev tiv thaiv corrosion yog qhov tsis muaj zog, tsis tuaj yeem tiv taus cov kua qaub thiab alkalis muaj zog, thiab yooj yim cuam tshuam nrog cov khoom siv tshuaj lom neeg no.
3. Lub zog ua haujlwm tsuas yog nyob hauv 10kg, uas tsis tuaj yeem siv rau hauv qhov chaw ua haujlwm siab.
4. Muaj zog hnav tsis kam, nws muaj ntau yam kev siv hauv kev thauj khoom.
5. Lub vojvoog khoov me me. Vim tias cov yeeb nkab PU mos thiab muaj qhov elasticity zoo, nws tsim nyog rau kev tsim cov kav dej.
6. PU raj muaj pob tshab siab, thiab lub xeev ntawm qhov nruab nrab ntws pom tseeb.
Lub hom phiaj ntawm PU yeeb nkab:
Nws yog tsim rau kev lag luam, kev ua liaj ua teb, khoom noj, tshuaj, kev tsim kho vaj tse, kev nuv ntses, kev cog qoob loo hauv dej, kev ywg dej rau vaj, roj tsis xeb thiab lwm yam teb. Yog tias nws xav tau kev tswj hwm lub neej ntev, nws yuav tsum nyob hauv qab qhov ntsuas siab ua haujlwm thiab siv ib puag ncig ntawm qhov kub. Thaum qhov kub nce, qhov siab ua haujlwm yuav tsum txo qis raws li. Yog tias qhov txwv tshaj, lub raj dej yuav tawg. Qhov kub ntawm cov kua dej siab dhau lossis cov kua dej muaj cov nqi tshuaj lom neeg corrosive, uas yuav ua rau lub raj dej tawg, qhov kub ntawm ib puag ncig ua haujlwm siab dhau lossis qhov chaw ua haujlwm muaj cov pa roj tshuaj lom neeg, uas yuav ua rau lub raj dej tawg, khaws cia rau hauv qhov chaw noo noo lossis lub sijhawm khaws cia ntev, nws yuav hydrolyze lossis laus lub raj dej, uas yuav ua rau tawg.
