Maswali Yanayoulizwa Mara kwa Mara<\/h2>\n
<\/p>\n
1. Kwa nini AZ275 ($275g\/m^2$) inachukuliwa kuwa chaguo bora kwa PPGL?<\/strong><\/p>\n
Uteuzi wa AZ275 unaashiria uzito mzito wa mipako ya $275g\/m^2$ ya aloi ya Alumini-Zinki. Ikilinganishwa na paneli za kawaida za AZ50 au AZ150, AZ275 hutoa safu nene ya kinga. Kulingana na ASTM A792, unene huu maalum umeundwa ili kuhimili hali mbaya zaidi ya angahewa, na kutoa hadi miaka 40 ya maisha ya huduma katika mazingira ya viwanda au pwani ambapo chuma cha kawaida kingeharibika haraka.<\/p>\n
2. Je, paneli za AZ275 PPGL zinaweza kuhimili mazingira ya baharini yenye chumvi nyingi?<\/strong><\/p>\n
Ndiyo. AZ275 PPGL yetu imeundwa mahsusi kwa ajili ya kategoria za C4 na C5 (Baharini\/Viwandani). Mchanganyiko wa substrate ya Aluminium-Zinc ya $55\\%$ na mfumo wa rangi wa PVDF uliojengwa kwa kiwango cha juu huhakikisha paneli zinapinga kutu na mashimo ya hewa ya chumvi. Ni kiwango cha dhahabu kwa miundo iliyojengwa ndani ya kilomita 1 kutoka ufuo au katika maeneo mazito ya viwanda yenye viwango vya juu vya dioksidi ya salfa.<\/p>\n
3. Kuna tofauti gani kati ya chuma cha mabati cha AZ275 na G90?<\/strong><\/p>\n
Ingawa G90 ni mipako nzito ya zinki ($275g\/m^2$ ya Zinki safi), AZ275 ni mipako nzito ya aloi ya Alumini-Zinki. Chini ya viwango vya ASTM, aloi ya Al-Zn (Galvalume) hutoa ulinzi bora wa kizuizi (shukrani kwa alumini) na uangazaji bora wa joto kuliko zinki safi. Katika matumizi mengi ya paa la nje, paneli ya AZ275 itadumu kwa kiasi kikubwa kuliko paneli ya mabati ya G90 kwa upande wa uadilifu wa kimuundo na uhifadhi wa rangi.<\/p>\n
4. Je, mipako nene ya AZ275 inaathiri umbo la paneli?<\/strong><\/p>\n
Sivyo hata kidogo. Licha ya unene mzito wa mipako, AZ275 PPGL yetu hutumia teknolojia ya hali ya juu ya kufyonza na kuendelea kwa kuchovya moto ili kuhakikisha aloi inabaki kuwa laini. Paneli hupita jaribio la kupinda la 0T-2T, ikimaanisha kuwa zinaweza kuviringishwa na kutengenezwa kuwa wasifu wa kina wa bati au trapezoidal bila kupasuka kidogo au kutenganishwa kwa tabaka za kinga.<\/p>\n
5. Ni mfumo gani wa rangi unaofaa zaidi kuunganishwa na substrate ya AZ275?<\/strong><\/p>\n
Ili kuongeza uwekezaji katika substrate nzito ya AZ275, tunapendekeza sana mipako ya PVDF (Polyvinylidene Fluoride) au HDP (High-Durability Polyester). Mifumo hii ya rangi hutoa upinzani wa juu zaidi wa UV (RUV4) na uthabiti wa kemikali, kuhakikisha kwamba umaliziaji wa urembo wa paa lako hudumu kwa muda mrefu kama ulinzi mzito wa Al-Zn chini yake.<\/p>\n
