Mifumo ya Mipako ya Kikaboni:<\/b> Kulingana na mazingira ya mradi wako, tunatoa finishes zenye utendaji wa hali ya juu ikiwa ni pamoja na Floridi ya polivinilidini (PVDF)<\/b> kwa upinzani wa juu wa UV, Polyester Iliyorekebishwa ya Silikoni (SMP)<\/b> kwa ajili ya kuimarisha upinzani wa chaki, na Polyester Imara Zaidi (HDP)<\/b>.<\/p>\n<\/li>\n<\/ul>\n
Upimaji Mkali wa Utendaji na Uzingatiaji<\/h2>\n
Ili kuhakikisha utendaji kama nyenzo ya "Daraja la Nje", koili zetu za ASTM A755 hupitia majaribio ya kina:<\/p>\n

1. Je, ASTM A755 Galvanized Coil ni nini?<\/strong><\/p>\n
ASTM A755\/A755M ni kiwango kilichochapishwa na Jumuiya ya Marekani ya Upimaji na Vifaa (ASTM) kwa ajili ya shuka\/koili za chuma zilizopakwa rangi ya moto na zilizopakwa koili kwa ajili ya ujenzi wa nje. Kanuni yake kuu ni sehemu ya chuma iliyopakwa rangi ya moto (aluminium-zinki\/alumini safi) yenye mipako ya kikaboni, iliyoundwa mahsusi kwa ajili ya vipengele vya nje vya jengo. Inasisitiza upinzani wa hali ya hewa, uundaji, na mshikamano wa mipako, na hubainisha shuka\/koili za chuma zilizopakwa rangi ya awali zenye sehemu ya chuma iliyopakwa rangi ya moto na filamu ya kikaboni iliyopakwa koili mfululizo. Inatumika kwa koili, shuka zilizokatwa kwa urefu, na sehemu zilizoundwa, zinazofunika shuka zilizobati, shuka zilizopakwa wasifu, vipengele vilivyopinda, na bidhaa zingine za ujenzi wa nje.<\/p>\n
2. Je, wewe ni mtengenezaji au kampuni ya biashara?<\/strong><\/p>\n
Sisi ni kiwanda chenye uzoefu wa mauzo wa zaidi ya miaka 10<\/p>\n
3. Unahakikishaje ubora?<\/strong><\/p>\n
1) Kutafuta kutoka kwa viwanda vya hali ya juu pekee na vilivyoidhinishwa.<\/p>\n
2) Kufanya ukaguzi wetu wa ndani wa QC kwa ukali.<\/p>\n
3) Kutoa Cheti rasmi cha Mtihani wa Kinu na udhamini wetu wa ubora kwa kila usafirishaji.<\/p>\n
