1. Kev piav qhia ntawm PVC cov vuas thiab cov ntaub pua tsev
PVC pobzeb yog ua los ntawm polyvinyl chloride resin (raug xa mus rau PVC) raws li cov khoom siv raw khoom, supplemented los ntawm UV anti-UV tus neeg saib xyuas thiab lwm cov ntaub ntawv raw khoom. Nws yog scientifically matched thiab ua nrog cov tshuab siab tshaj. PVC pobzeb, los yog lub hnab yas pobzeb, yog lub cim tshiab ntawm cov xim pobzeb xim. Cov txheej txheem multi-layer coextrusion compounding yog siv rau cov nplais ntawm cov khoom siv los npog cov txheej laus los tiv thaiv, uas ua rau cov huab cua tsis kam thiab cov xim xim, thiab txheej txheej ntxiv rau hauv qab nto. Nws muaj cov hluav taws kub zoo, tiv thaiv corrosion, huab cua ua hauj, tsis muaj cov khoom xyaw asbestos, cov xim ci, kev tiv thaiv ib puag ncig thiab kev noj qab haus huv. Nws yog dav siv nyob rau hauv lub ru tsev thiab phab ntsa ntawm loj-span gantry qauv Hoobkas, uas tsis tsuas yog ua raws li kev tiv thaiv corrosion ntawm lub teeb steel qauv kev cob qhia, tab sis kuj txuag hlau thiab txo nqi.
Cov vuas luaj raug muab faib ua cov vuas ntuj thiab cov khoom siv hluavtaws tuaj. Cov resins xa mus rau hauv kev ua lag luam yog cov khoom hluav taws xob feem ntau. Cov hluavtaws pobzeb tsim tau tsim los ntawm SABIC, lub ntiaj teb sab saum toj 500 tuam txhab, nrog huab cua engineering cob qha ASA. ASA yog ib tug terpolymer uas muaj Acrylonitrile, Styrene, thiab Acrylate.
2. Cov yam ntxwv ntawm PVC vuas thiab cov ntaub pua tsev
(1) PVC pobzeb nta
1, ntawd nqe, nws yog pheej yig thiab ua tau zoo
2, hluav taws ua hauj - oxygen index OI ≥ 32, yog cov khoom siv hluav taws kub nyhiab;
3, los tiv thaiv corrosion - tshuaj txhuam cov tshuaj muaj zog, ntau dua 3 zaug ntev tshaj zinc phaj lub neej;
4, muaj zog toughness - feem xyuam, tensile tsis kam, tsis txhav;
5, huab cua tsis kam - vim qhov sib ntxiv ntawm UV los tiv thaiv-UV tus neeg ua hauj lwm hauv cov khoom, qhov khoom yuav ua tau tiag los tiv thaiv hluav taws xob ultraviolet, lub neej ntev;
6, qes qis - suab nrov heev thaum nws los nag, lub suab ntawm lub vaj huam sib luag hlau raug txo los ntawm ntau dua 30db;
7, kev txav khoom - yooj yim rau nruab, thauj, txuag lub sijhawm thiab kev rau siab;
8, zoo nkauj - ci xim, ci thiab yeeb yuj;
9, kev tiv thaiv ib puag ncig - tsis muaj cov khoom xyaw asbestos, tsis muaj carcinogenic thiab lwm yam khoom tso tawm.
Disadvantage
1. Tsis tshua muaj kev ruaj ntseg rau lub teeb thiab cua sov
2. Cov txheej txheem kub thiab zij zis yuav kub heev, uas ua rau nyuaj thiab xav tau kev daws teeb meem los ntawm cov khoom siv ntxiv.
3. Yooj yim rau ploj thaum siv sab nraum zoov
(2) Yam ntxwv ntawm cov pobzeb phaj
Ntev ntev ntev
Synthetic resin nplais deg khoom yog ua los ntawm kev siv ultra-siab huab cua resistant engineering cob. Nws muaj exceptability nyob rau hauv qhov ntuj environment, thiab nws tswj nws cov xim stability txawm nyob rau hauv ntev raug ultraviolet teeb, noo noo, tshav kub thiab txias. Raws li cov txiaj ntsim ntawm kev siv sab nraum zoov hauv cov cheeb tsam uas muaj lub hnub ci thiab lwm qhov chaw xws li Arizona thiab Florida, nws muaj peev xwm ua kom muaj kev hloov xim kaum xyoo rau ΔE ≤ 5.
Synthetic resin corrugated arc huab cua tsis kam kuaj
Qhov xaus hais tias cov qauv raug irradiated nrog lub kaum ntawm 450 hnub ci nyob rau hauv ntau qhov chaw, zoo tsis kam mus load.
Synthetic resin vuas muaj peev xwm nqa tau zoo. Hauv cov cheeb tsam uas tsis tshua muaj kev kub ntxhov, cov khoom siv hluavtaws tuaj yeem tsis ua rau puas tsuaj thiab tawg txawm tias lub ru tsev tau them npu txhua xyoo. Tom qab kuaj, nrog ib qho kev txhawb nqa ntawm 660mm, loading 150kg, lub pobzeb yuav tsis keej thiab ua puas.
Mloog zoo nkauj
Cov kev kuaj pom tau hais tias cov khoom siv hluavtaws tuaj yeem ua tau zoo ntawm lub suab nrov thaum lub suab nrov sab nraud xws li nag los yog cua daj cua dub.
Txhaum corrosion kuj zoo kawg thiab
Synthetic resin vuas tuaj yeem tiv thaiv corrosion ntawm ntau yam tshuaj xws li acids, alkalis thiab ntsev ntev. Cov kev sim proves tias tsis muaj tshuaj lom neeg cov tshuaj tiv thaiv tom qab so rau 24 teev hauv ntsev, alkali thiab 60% ntawm cov acids ntau. Nws yog ib qho tsim nyog rau siv nyob rau hauv cov cheeb tsam qis-roj thiab chaw xeeb tub, thiab qhov tshwm sim yog tshwj xeeb tshaj yog zoo kawg.
Kev tiv thaiv hluav taws
Synthetic resin vuas yog ib yam khoom uas tsis yog-hluav taws kub, uas tau kuaj los ntawm tsoomfwv cov koom haum tiv thaiv hluav taws raws li tus qauv GB8624-2006, thiab kev tua hluav taws yog ≥B1.
Kev ua haujlwm zoo thiab ua haujlwm tsis muaj zog
Synthetic resin vuas yog ib qho muaj zog sab nraud muaj peev xwm. Tom qab kuaj 1 kg ntawm cov npas hlau dawb poob los ntawm 3 meters siab, tsis muaj kev nrib pleb yuav tshwm sim, thiab tej yam tsis kam ntawm tsawg kub kuj tseem ceeb heev.
