Daim Ntawv Thov

1. Kev tiv thaiv tseem ceeb rau cov khoom siv roj hmab: tiv thaiv kev laus thiab lub neej ua haujlwm ntev

Qhov no yog nws daim ntawv thov tseem ceeb, muab kev tiv thaiv tseem ceeb tiv thaiv cov teeb meem laus ntawm roj hmab los ntawm "kub, ozone, thiab oxidation" thaum siv (xws li hardening, cracking, thiab txo elasticity).

Kev tsim cov log tsheb: Nws yog siv rau hauv cov roj hmab sib xyaw ua ke ntawm cov tread thiab sidewall ntawm ntau hom log tsheb xws li tsheb, tsheb thauj khoom, thiab cov tshuab tsim kho kom tiv taus qhov kub uas tsim los ntawm kev sib txhuam thaum lub sijhawm ua haujlwm ntawm lub tsheb thiab kev puas tsuaj ntawm ozone hauv huab cua, ncua qhov laus thiab tawg ntawm cov log tsheb, thiab txuas ntxiv lawv lub neej kev pabcuam.

Cov khoom siv roj hmab rau kev lag luam: Haum rau cov yeeb nkab roj hmab (xws li cov kav dej roj thiab roj av), cov siv conveyor (rau kev khawb av thiab kev xa khoom), thiab cov foob (O-rings, gaskets), los tiv thaiv cov khoom no kom tsis txhob laus ua ntej thiab tsis ua haujlwm thaum raug rau sab nraum zoov lossis qhov chaw hnyav (xws li qhov kub thiab txias thiab av noo) ntev.

Cov khoom siv roj hmab siv txhua hnub/tshwj xeeb: siv rau cov roj hmab so, cov roj hmab gaskets, roj hmab nqus kev co (rau tsheb/tshuab), nrog rau cov khoom ua los ntawm roj hmab hluavtaws xws li roj hmab chloroprene thiab roj hmab styrene-butadiene, tswj lawv lub elasticity thiab kev ua tau zoo mus sij hawm ntev hauv kev siv.

2. Cov tshuaj tiv thaiv roj hmab rau cov xwm txheej tshwj xeeb

Ntxiv rau kev tiv thaiv dav dav, cov teeb meem kev laus tshwj xeeb kuj tseem tuaj yeem daws tau raws li qhov chaw siv cov khoom siv roj hmab:

Kev laus tiv thaiv kev qaug zog ntawm lub cev: Nws yog siv rau cov khoom siv roj hmab uas yuav tsum tau ua rau muaj zog ntau zaus (xws li cov siv conveyor thiab cov absorbers), txo qhov "qaug zog tawg" uas tshwm sim los ntawm kev sib xyaw ua ke ntawm kev ntxhov siab dynamic thiab oxidation.

Kev pab tiv thaiv kub siab: Hauv cov khoom siv roj hmab siv rau hauv qhov chaw kub nruab nrab thiab kub siab (xws li cov foob ntawm lub cav), thaum sib xyaw nrog lwm cov tshuaj antioxidants, nws ua rau cov roj hmab tiv taus cua sov thiab tiv thaiv nws kom tsis txhob tawv sai thiab ua rau tawg ntawm qhov kub siab.

Feature

1. Kev huv huv ≥ 99.99%, tshaj tus qauv kev lag luam roj teeb;
2. Cov dej noo noo ≤50 ppm, qhov kev ua tau zoo ntawm kev rwb thaiv tsev zoo heev;
3. Kev ruaj khov thermal zoo heev
4. Muaj nyob rau hauv Tshuag
