Thaum hloov qhov ntsuas kub thiab av noo ntawm Stevenson npo (cov cuab yeej vaj tse) hauv Philippines 'kub thiab av noo, cov khoom siv ASA yog qhov kev xaiv zoo tshaj ABS. Hauv qab no yog kev sib piv ntawm lawv cov yam ntxwv thiab cov lus pom zoo:
1. Cov khoom siv sib piv
| Khoom | ASA | ABS |
|---|---|---|
| Huab cua Resistance | ⭐⭐⭐⭐⭐ ib UV-resistant, withstands kub thiab av noo, tsis discolor los yog nkig nyob rau hauv lub hnub raug ntev | ⭐⭐ Ib Nyuaj rau UV degradation, yellows nyob rau lub sij hawm, yuav deform nyob rau hauv lub sij hawm ntev humid tej yam kev mob |
| Corrosion Resistance | ⭐⭐⭐⭐ ib Resistant rau ntsev tsuag thiab kua qaub los nag, haum rau cov ntug hiav txwv dej (piv txwv li, Philippines) | ⭐⭐⭐ ib Kev ua haujlwm nruab nrab, tab sis kev ya raws ntev yuav ua rau cov qauv tsis muaj zog |
| Mechanical Strength | ⭐⭐⭐⭐ ib Khaws lub zog ntawm qhov kub thiab txias | ⭐⭐⭐⭐ ib Muaj zog ntawm chav tsev kub tab sis softens hauv tshav kub |
| Qhov kub thiab txias | -30 ° C txog 80 ° C (ruaj khov) | -20 ° C txog 70 ° C (tej zaum yuav deform ntawm qhov kub siab dua) |
| Nqi | Siab dua (~ 20% -30% kim dua ABS) | qis |
2. Kev nyab xeeb rau Philippines
- High Humidity & Thaum tshav kub kub: ASA ua tau zoo dua nyob rau lub sij hawm ntev raug rau cov nag los nag thiab cua sov yam tsis muaj warping.
- Strong UV Exposure: ASA muaj UV stabilizers, ua rau nws zoo tagnrho rau Philippines 'hnub ci hnyav, tiv thaiv qhov tseeb ntawm qhov poob vim cov khoom degradation.
- Salt Spray Corrosion: Yog tias ze rau thaj tsam ntawm ntug dej hiav txwv (xws li Manila, Cebu), ASA cov ntsev tiv thaiv ua kom lub zog ntev dua.
3. Kev tu thiab kev ua neej nyob
- ASA: kav 10-15 xyoo, yuav tsum tau saib xyuas tsawg.
- ABS: Tej zaum yuav xav tau kev hloov pauv txhua 5-8 xyoo, uas tuaj yeem nce nqi mus ntev.
4. Pom zoo xaiv
- Kev xaiv zoo tshaj plaws: ASA - Zoo tagnrho rau chaw nres tsheb huab cua mus tas li, thaj chaw ntug hiav txwv, thiab thaj chaw tshav ntuj.
- ABS Alternative - Tsuas yog siv sijhawm luv luv lossis nruj pob nyiaj siv, nrog kev tshuaj xyuas ntau zaus rau kev degradation.
5. Cov lus qhia ntxiv
- Xaiv cov xim dawb lossis xim xim Stevenson cov ntxaij vab tshaus kom txo qhov nqus cua sov.
- Xyuas kom tus qauv tsim ua raws li WMO (World Meteorological Organization) cov qauv ntsuas cua kom raug ntsuas ntsuas qhov tseeb.
Muab rau Philippines cov kev sib tw huab cua, cov khoom siv ASA, txawm tias nws cov nqi pib ntau dua, txo cov nqi tu mus sij hawm ntev thiab cov ntaub ntawv tsis raug.
