Bitumen PG 58/34 hais txog cov qib tshwj xeeb ntawm kev ua tau zoo-qib (PG) bitumen, feem ntau siv hauv kev tsim kho asphalt pavement. Qhov "PG" kev muab qhab nia yog raws li cov bitumen qhov kev ua tau zoo ntawm qhov sib txawv ntawm qhov kub thiab txias, kom ntseeg tau tias nws tuaj yeem tiv taus qee qhov kev nyab xeeb.

Kev tawg ntawm PG 58-34:

• PG: Stands rau "Performance Grade," ib qho kev tsim kho raws li Txoj Haujlwm Kev Tshawb Fawb Txoj Kev Loj (SHRP).

• 58: Sawv cev rau qib siab kub hauv degrees Celsius. Nyob rau hauv cov ntaub ntawv no, lub bitumen yog tsim los ua tau zoo nyob rau hauv kub txog li 58 ° C yam tsis ua heev mos los yog rutting.

• -34: Sawv cev rau qib qis qis hauv degrees Celsius. Cov bitumen yog tsim los ua haujlwm zoo nyob rau hauv qhov kub thiab txias li -34 ° C yam tsis muaj nkig lossis tawg.

Yam ntxwv:

• Kev Ua Haujlwm Kub Kub: Resistant rutting thiab deformation ntawm qhov kub thiab txias (txog 58 ° C).

• Low-Temperature Performance: Tiv thaiv thermal tawg ntawm qhov kub thiab txias (txog -34 ° C).

• Elastic rov qab: Muab zoo elasticity thiab durability nyob rau hauv tsheb thauj khoom thiab kub hloov pauv.

Daim ntaub ntawv:

• Cov huab cua txias: Zoo tagnrho rau cov cheeb tsam uas tsis tshua muaj lub caij ntuj no kub, raws li nws tseem yoog raws thiab tiv taus tawg.

• Nruab nrab mus rau High Traffic Loads: Haum rau txoj kev loj, txoj kev, thiab lwm yam pavements raug kev tsheb loj.

Cov Qauv:

• PG-qib bitumen raug kuaj thiab cais raws li UAS M 320 or ASTM D6373 cov qauv kawm.

Kev siv Asphalt 58/34

Kev tsim kho txoj kev: Bitumen muaj 58/34 yog siv dav hauv kev tsim kho kev tsim kho vim nws muaj peev xwm tiv taus cov tsheb thauj khoom hnyav thiab huab cua hnyav.

Waterproofing: Nws ua haujlwm zoo waterproofing tus neeg sawv cev, tiv thaiv cov qauv ntawm cov dej infiltration thiab ua kom lawv lub neej ntev.

Roofing: Nws yog feem ntau siv rau hauv cov ntaub ntawv vov tsev xws li daim nyias nyias thiab shingles, muab cov huab cua tiv thaiv zoo thiab rwb thaiv tsev.

Kev Siv Hluav Taws Xob: Nws pom cov ntawv thov hauv ntau qhov chaw tsim khoom rau txheej txheej, adhesives, thiab sealants, ua tsaug rau nws cov nplaum thiab tiv thaiv cov yam ntxwv.

Ntim lub ntsiab

Ntim rau hauv cov thawv ntim khoom zoo tsim los tiv thaiv kev sib kis, noo noo, thiab kub hloov pauv. Kev ruaj ntseg ntim cov kev daws teeb meem kom ntseeg tau cov khoom lag luam zoo thaum thauj thiab khaws cia.

zoo 

Durability: Nws txhim khu lub durability ntawm kev tsim kho, txo cov nqi tu lub sijhawm.

Versatility: Bitumen 58/34 yog ntau yam thiab tuaj yeem siv tau ntau yam kev siv thoob plaws kev lag luam sib txawv.

Nqi-effectiveness: Nws muab cov kev daws teeb meem zoo uas tsis muaj kev cuam tshuam rau qhov zoo lossis kev ua haujlwm.

Kev Saib Xyuas Ib Puag Ncig

Kev siv zog tau tsim los txhim kho eco-friendly formulations ntawm Bitumen 58/34, tsom rau kev ruaj khov thiab txo cov kev cuam tshuam ib puag ncig thaum tsim khoom thiab siv cov txheej txheem.
