Cov ntxhiab tsw ntxhiab ntawm PU Tube hauv kev pabcuam yog nyob ntawm cov khoom siv raw zoo, hnub nyoog ntawm lub raj, kev ua haujlwm kub thiab kev laus. Cov qhabnias siab- zoo PU Tube tsuas yog tso tawm tau luv luv - nyob tsis tswm, thaum tsis tu ncua pungent tsw tsuas yog tshwm sim hauv cov hlab ntsha tsis zoo lossis ua haujlwm hnyav. Cov ntxhiab tsw tuaj yeem muab faib ua plaub qhov xwm txheej: hom- cov raj tshiab, kev ua haujlwm ib txwm muaj, siab- kub aging thiab qis- qib rov ua dua- cov khoom siv.
Lub hom phiaj - tshiab PU Tube ua los ntawm cov ntaub ntawv nkauj xwb khaws cov ntxhiab tsw tsw qab heev tom qab tsim khoom. Cov ntxhiab tsw tsis yog- khaus, tsis yog- tshuaj lom thiab tsis yog- corrosive, thiab tsis muaj cov pa phem tsis zoo. Cov ntxhiab tsw no yog los ntawm cov khoom seem seem ntawm cov khoom siv raw cov ntaub ntawv uas tau tsim thaum lub sij hawm siab -kub extrusion thiab molding es tsis yog tshuaj lom neeg decomposition. Hauv qhov dej zoo-cov chaw ua haujlwm cua lossis chaw nyob sab hauv tsev, cov ntxhiab tsw seem evaporates tag nrho hauv 3 mus rau 15 hnub ntawm qhov cua tsis tu ncua. Tsis muaj ntxhiab tsw yuav tshwm sim tom qab ntev- siv sijhawm ntev thiab nws tsis ua rau muaj kev phom sij rau tib neeg cov neeg ua haujlwm, khoom siv lossis cov xov xwm xa tawm, yog li nws tuaj yeem siv nyab xeeb hauv cov xwm txheej kev lag luam thiab pej xeem.
Tsim nyog PU Tube ua rau tsis muaj ntxhiab tsw thaum lub sij hawm ib txwm chav- kub ua haujlwm. Polyurethane muaj cov yam ntxwv ntawm cov tshuaj ruaj khov thiab tsis decompose los yog tso cov khoom tsis haum rau hauv chav tsev kub. Nws cov khoom siv nyob ruaj khov yam tsis tso cov ntxhiab tsw los yog teeb meem roj molecules. Tsis muaj ntxhiab tsw tshwm sim seb lub raj nyob li qub lossis ua haujlwm tsis muaj zog rau huab cua, dej thiab qis -siab nruab nrab kis. Nws suits kaw rhiav, khoom interiors thiab sab hauv tsev civil ib puag ncig nrog nruj tsw yuav tsum tau.
PU Tube tso tawm me ntsis tsw nyob rau hauv qhov kub thiab txias, raug tshav ntuj thiab kev laus. Thaum ambient kub yog siab dhau heev lawm los yog lub raj oxidizes thiab degrades maj mam nyob rau hauv lub tshav ntuj ntev, polyurethane molecules muaj qeeb me volatilization thiab tsim faint yas tsw. High-zoo hloov kho siab-kub-resistant PU Tube generates NW nyuam qhuav perceptible tsw nyob rau hauv tshav kub. Ordinary PU Tube tso tawm me ntsis tsis hnov tsw ntau dua nyob rau hauv ib puag ncig siab tshaj 60 degree, tseem tsis muaj cov pa phem tawm. Yog hais tias lub raj muaj hnub nyoog hnyav heev thiab dhau los ua hmoov, ntxhiab tsw intensifies moderately. Hauv qhov no, lub raj xa mus rau qhov tsis ua haujlwm thiab kev hloov pauv tau pom zoo kom sai.
Tsawg- qib PU Tube rov ua dua yog qhov tseem ceeb ntawm cov ntxhiab tsw zoo. Tsawg-tus nqi PU Tube nyob rau hauv kev ua lag luam yog reprocessed los ntawm pov tseg polyurethane thiab cov khoom seem yas nrog complex compositions thiab ntau impurities. Ntau qhov ntau ntawm cov tshuaj ntxiv thiab cov stabilizers tau ntxiv thaum tsim khoom. Cov raj zoo li no muaj cov ntxhiab tsw ntxhiab tsw ntxhiab thiab cov tshuaj lom neeg muaj zog tawm ntawm kev tsim khoom, uas ua rau pom tseeb tshwj xeeb hauv cov chaw kaw. Cov ntxhiab tsw tsis tuaj yeem ploj mus sai sai thiab tso tawm cov tsis kaj siab volatiles thaum ua haujlwm. Sib nrug los ntawm kev ua qias tuaj rau ib puag ncig ua haujlwm, qee qhov tsis zoo los ntawm qhov tsis zoo - cov raj zoo yuav ua rau tib neeg noj qab haus huv. Lawv raug txwv tsis pub noj zaub mov, kev kho mob thiab kev nyob ib puag ncig lossis chaw ua haujlwm.
Raws li qhov tseeb, PU Tube tiag tiag tsuas muaj cov ntxhiab tsw me me nyob rau theem pib thiab tseem tsw qab - pub dawb thoob plaws hauv kev pabcuam. Cov teeb meem tsw tsuas yog tshwm sim hauv cov hlab ntsha tsis zoo lossis kev laus ua haujlwm hnyav. Kev yuav cov khoom muaj ntawv pov thawj tsis tu ncua thiab siv kev tiv thaiv kev ua haujlwm kom zoo tuaj yeem zam qhov teeb meem tsw ntxhiab.
