Papa kila AR400

Wehewehe Pōkole:

He papa kila metala kalapona kiʻekiʻe ka papa kila kū i ka abrasion (AR). ʻO ke ʻano kēia, ʻoi aku ka paʻakikī o ka AR ma muli o ka hoʻohui ʻia ʻana o ke kalapona, a hiki ke hoʻokumu ʻia a kū i ka wā ma muli o nā metala i hoʻohui ʻia.

Nā noi papa kila kūpaʻa abrasion

● Ua manaʻo ʻia nā papa AR235 no nā noi ʻaʻahu kaulike kahi e hāʻawi ai i ka pale ʻaʻahu i hoʻomaikaʻi ʻia e pili ana i ke kila kalapona kūkulu.
● He mau papa kila kūpaʻa kiʻekiʻe ka AR400 i mālama ʻia i ka wela a hōʻike i ka paʻakikī. Hoʻomaikaʻi ʻia ke kūkulu ʻana a me ka hoʻopaʻa ʻana.
● He pā kū i ka ʻānai ʻia ʻana o AR450 i hoʻohana ʻia i nā ʻano hana like ʻole kahi e makemake ʻia ai ka ikaika ʻoi aku ka nui ma mua o AR400.
● He kūpono nā papa AR500 no nā hana eli ʻana, nā hana ululāʻau a me ke kūkulu ʻana.
● Hoʻohana ʻia ʻo AR600 ma nā wahi i hoʻohana nui ʻia e like me ka wehe ʻana i nā ʻōpala, ka eli ʻana, a me ka hana ʻana i nā bākeke a me nā kino hoʻohana.
ʻO ka maʻamau, hana ʻia ka papa kila Abrasion Resistant (AR) i ke ʻano i ʻōwili ʻia. Ua hoʻomohala kūikawā ʻia kēia mau ʻano/papa o nā huahana papa kila no ke ola lawelawe lōʻihi ma nā kūlana ʻino.
