Puas tau xav txog seb dab tsi ua rau cov xov hlau hauv koj lub tsev, chaw ua haujlwm, lossis lub tsheb ua haujlwm tau zoo—txawm tias lawv raug khi rau hauv qab lub ru tsev kub, faus hauv av, lossis raug sib tsoo thaum siv txhua hnub? Cov lus teb nyob rau hauv ib qho khoom me me tab sis muaj zog: PVC stabilizers. Cov khoom ntxiv no tsis tshua muaj neeg paub yog vim li cas koj cov xov hlau hluav taws xob tsis yaj, tawg, lossis hloov pauv brittle dhau sijhawm. Cia peb kawm seb vim li cas lawv tsis sib haum rau cov xov hlau thiab cov cables, thiab hom twg sawv tawm.
Ua Ntej: Vim Li Cas PVC Thiaj Tseem Ceeb Rau Cov Hlau Thiab Cov Cables
PVC (polyvinyl chloride) muaj nyob txhua qhov chaw hauv cov xov hlau. Nws yog cov khoom rwb thaiv tsev uas yoog tau thiab ruaj khov uas qhwv ib ncig ntawm cov xov hlau tooj liab, tiv thaiv lawv ntawm cov dej noo, cua sov, thiab kev puas tsuaj rau lub cev. Tab sis ntawm no yog qhov teeb meem: PVC tsis ruaj khov. Thaum raug rau qhov kub siab (xws li los ntawm hluav taws xob), UV rays, lossis txawm tias lub sijhawm, nws pib tawg. Qhov kev tawg no tso tawm cov tshuaj lom neeg (xws li chlorine) thiab ua rau lub rwb thaiv tsev tsis muaj zog - xov xwm phem thaum lub rwb thaiv tsev ntawd tsuas yog qhov sawv ntawm koj thiab luv luv lossis hluav taws xwb.
Nkag mus rau PVC Stabilizers: Lub Shield Tiv Thaiv
Cov khoom ruaj khov zoo li cov neeg tiv thaiv rau PVC rwb thaiv tsev. Lawv:
Tiv thaiv kev puas tsuaj los ntawm cua sovCov xov hluav taws xob tsim cua sov, thiab cov stabilizers tiv thaiv PVC kom tsis txhob yaj lossis lwj thaum kub nce (xav txog 70 ° C + hauv lub thawv sib txuas uas muaj neeg coob coob).
Tiv thaiv cov teeb meem UVRau cov xov hlau sab nraum zoov (xws li cov uas siv hluav taws xob rau teeb pom kev ntawm txoj kev), cov khoom ruaj khov thaiv lub hnub ci kom tiv thaiv kev rwb thaiv tsev kom tsis txhob tawg lossis ploj mus.
Tsis txhob brittlenessSiv tau ntau xyoo, PVC tuaj yeem tawv thiab tawg. Cov khoom ruaj khov ua rau nws yoog tau, txawm tias nyob hauv chav nres tsheb txias lossis chav tsev kub.
Tswj kev nyab xeeb ntawm hluav taws xobLos ntawm kev khaws cia qhov ruaj khov ntawm cov khoom rwb thaiv tsev, lawv tiv thaiv cov hluav taws xob luv luv, xau, thiab hluav taws xob.
Cov Khoom Siv Ruaj Khoov Zoo Tshaj Plaws rau Cov Hlau thiab Cov Cables
Tsis yog txhua lub stabilizers ua haujlwm tau zoo. Nov yog cov kev xaiv zoo tshaj plaws rau kev txuas hluav taws xob:
1. Cov Khoom Siv Calcium-Zinc StabilizersMuaj Kev Nyab Xeeb & Ib puag ncig-phooj ywg
Cov no yog tus qauv kub rau kev siv hluav taws xob niaj hnub thiab muaj kev nyab xeeb:
Tsis muaj tshuaj lomTsis muaj cov hlau hnyav (xws li cov hlau lead lossis cadmium), lawv ua tau raws li cov qauv kev nyab xeeb nruj (REACH, RoHS) rau kev siv sab hauv tsev thiab sab nraum zoov. Zoo meej rau cov tsev, tsev kawm ntawv, thiab tsev kho mob uas kev nyab xeeb yog qhov tseem ceeb.
Kev tiv taus kub thiab UVLawv tswj tau qhov kub nruab nrab (txog li 90°C) thiab sab nraum zoov, ua rau lawv zoo heev rau kev txuas hluav taws xob hauv tsev thiab cov xov hluav taws xob qis (xws li cov xov USB).
Yooj yim rau kev ua tiavThaum lub sijhawm tsim khoom, lawv sib tov zoo nrog PVC, kom ntseeg tau tias cov khoom rwb thaiv tsev tsis muaj qhov sib txawv lossis qhov tsis muaj zog.
2. Cov Khoom Siv Barium-Zinc Stabilizers: Ruaj rau Cov Cables Xav Tau Siab
Thaum cov xov hlau xav tau kev tswj hwm qhov xwm txheej hnyav, barium-zinc stabilizers nce qib:
Kev kam rau siab kubLawv vam meej nyob rau hauv qhov chaw kub (105 ° C +), ua rau lawv zoo tagnrho rau cov xov hlau kev lag luam, cov xov hlau tsheb (hauv qab lub hood), lossis cov xov hluav taws xob siab.
Kev ruaj khov mus sij hawm ntevLawv tiv taus kev laus, yog li cov cables kav ntev li 20+ xyoo txawm tias nyob rau hauv qhov chaw nyuaj (xws li cov chaw tsim khoom lossis huab cua hauv hav zoov).
Tus nqi tsim nyogLawv sib npaug kev ua tau zoo thiab tus nqi, ua rau lawv nyiam rau cov haujlwm loj (xav txog cov hluav taws xob lossis cov tsev lag luam).
3. Cov Khoom Siv Tin Organic Stabilizers: Kev Ua Kom Tiav Rau Cov Ntawv Thov Tseem Ceeb
Cov no yog siv rau hauv cov cables tshwj xeeb, kev ua haujlwm siab:
Kev rwb thaiv tsev uas pom tseebLawv ua kom PVC pob tshab, uas muaj txiaj ntsig zoo rau cov xov hlau fiber optic lossis cov xov hlau kho mob qhov twg pom kev tseem ceeb.
Kev tsiv teb tsaws chaw tsawg heevLawv tsis tawm cov tshuaj lom neeg, ua rau lawv muaj kev nyab xeeb rau cov chaw rhiab heev (xws li cov khoom siv kho mob lossis cov chaw ua zaub mov).
Lus Cim: Lawv kim dua li calcium-zinc lossis barium-zinc, yog li lawv tau tshwj tseg rau kev siv niche.
Yuav ua li cas yog tias koj tsis siv cov stabilizer?
Xaiv lub stabilizer tsis raug (lossis tsawg dhau) tuaj yeem ua rau muaj kev puas tsuaj:
Cov kab nrib pleb ntawm cov khoom rwb thaiv tsevCov dej noo nkag mus rau hauv, ua rau luv luv lossis hluav taws xob poob siab.
Yaj hauv qab cua sovCov xov hlau nyob rau hauv cov chaw kub (xws li tom qab TVs) tuaj yeem yaj, ua rau muaj hluav taws.
Ua tsis tiav ua ntej lub sijhawmTej xov hlau yuav xav tau hloov hauv 5-10 xyoo es tsis yog 30+ xyoo, uas siv sijhawm thiab nyiaj txiag ntau.
Yuav Ua Li Cas Thiaj Pom Tau Cov Khoom Siv Ruaj Khov Zoo Hauv Cov Cables
Thaum yuav cov xov hlau lossis cov cables, nrhiav cov hauv qab no:
Cov Ntawv Pov ThawjCov ntawv lo xws li "UL Listed" (Tebchaws Meskas) lossis "CE" (EU) txhais tau tias cov xov hlau tau dhau qhov kev xeem kev nyab xeeb - suav nrog kev ua haujlwm ntawm lub stabilizer.
Kev ntsuas kubCov xov hlau uas muaj cim "90°C" lossis "105°C" siv cov khoom ruaj khov uas ua rau cua sov.
Lub koob npe nrov ntawm hom lag luamCov chaw tsim khoom uas ntseeg siab (xws li Prysmian lossis Nexans) nqis peev rau cov khoom ruaj khov zoo kom tsis txhob raug hu rov qab.
Lub Tswv Yim Kawg: Cov Khoom Ruaj Khoov = Cov Hlau Txhim Khu Kev Ruaj Ntseg, Muaj Kev Nyab Xeeb
Lub sijhawm tom ntej koj ntsaws ib lub cuab yeej lossis tig lub teeb, nco ntsoov: cov khoom rwb thaiv tsev PVC nyob ib puag ncig cov xov hlau ntawd tshuav nws lub zog rau cov khoom ruaj khov. Txawm nws yogcalcium-zincrau koj lub tsev los yogbarium-zincrau cov xov hlau hauv kev lag luam, lub stabilizer zoo ua rau hluav taws xob ntws tau zoo - hnub no, tag kis, thiab rau ntau xyoo tom ntej.
Tom qab tag nrho, thaum nws los txog rau cov xov hlau, "tsis pom" yuav tsum tsis txhob txhais hais tias "tsis nco qab." Qhov zoo tshaj plawscov tshuaj stabilizerua haujlwm ntsiag to, yog li koj tsis tas yuav txhawj.
