ʻO Phillips Pan Head Self-Drilling and Self-Tapping Screw (Paina National Standard GB/T15856.1-2002)

2. Nā mea maka a me nā kaʻina hana

Me ka hoʻohana ʻana i ke kila kalapona kiʻekiʻe, ʻaʻole maʻalahi ka haʻihaʻi ʻana o ka ʻili kila lahilahi i ka wā e wili ai. Ke kaʻina hana: nā kiʻi ʻoniʻoni maka - annealing, phosphating, ke kaha kiʻi maikaʻi, ke poʻo anu, ka hana ʻana o ka huelo, ka ʻōwili ʻana i ka lola, ka hoʻoponopono ʻana i ka wela, ka mālama ʻana i ka zinc plating, ka hoʻopili. ʻAʻole e hoʻopuʻu ʻia ke poʻo pan poʻe ʻaʻole e ʻānai i ka ʻili pena o ka mea hana ma hope o ka hui ʻana; paʻa a piha ka ʻaoʻao o ke kaula, a ʻaʻole maʻalahi ka paheʻe ʻana a me ka haki ʻana o ka panel lahilahi laka; ʻO ka polū-keʻokeʻo zinc plated coating he mānoanoa a like.

3. Nā pono kumu waiwai

ʻAʻole hoʻopōʻino ke poʻo arc pan i ka mea hana: ʻo ke poʻo o ka pan pōʻai he poʻo pā maʻemaʻe, a kūpono ka ʻili disk i ka ʻili panel ma hope o ka laka ʻana. ʻAʻohe ʻaoʻao ʻoi a me nā kihi, ʻaʻole ia e ʻoki i ka uhi ʻana o ka ʻili o ka plastik a me ka metala. ʻOi aku ka maikaʻi no ka hui kūloko o nā mea hana hale.

ʻO ke kūlana aupuni Kina i nā kikoʻī piha piha o nā kikoʻī: kahi piha piha o ka nui o ka lāhui Kina, e pili ana i nā ʻāpana kila i ʻōwili ʻia a me nā papa zinc plated o nā mānoanoa like ʻole mai 2 a 6mm, e hālāwai ana i nā pono hui o nā ʻāpana he nui o nā panela lahilahi i hoʻokahi kū.

ʻO nā koho maʻalahi no nā uhi he nui: ʻo ka zinc polū-keʻokeʻo maʻamau ka mea kūʻai aku a hiki ke hoʻohana ʻia i loko o ka hale; ʻoi aku ke kūpaʻa o ka zinc plated i ka paʻakai paʻakai a hiki ke hoʻohana ʻia i nā lako semi-open-air; he haʻahaʻa ke kumu kūʻai ʻeleʻele oxide a hiki ke hoʻohana ʻia no ka hui huna ʻana i loko o ka lako.

4. ʻO ka mālama ʻana i ka maikaʻi a me nā lawelawe kākoʻo

Loaʻa nā kikoʻī maʻamau o Kina a pau. Hoʻouna ʻia nā kauoha maʻamau i loko o 48 mau hola. Hiki ke ʻae ʻia nā ʻāpana liʻiliʻi a me nā kauoha hoʻopuka piha piha. Ma mua o ka haʻalele ʻana i ka hale hana, ʻike ʻia ka nui o ke poʻo pan, Phillips recess ikaika, drill point hardness, a me ka hoʻopili ʻana i ka uhi ʻana e like me nā kūlana aupuni Kina, a ua hoʻopau ʻia nā huahana kīnā ʻole me nā puʻupuʻu chipped, nā ʻaoʻao haʻihaʻi, a me nā pale kīnā. Hiki ke hoʻohana ʻia me ka countersunk head drill point, hexagonal drill point, a me nā ʻano kīwī paʻi ponoʻī ʻokoʻa piha o nā hoʻouna; Kākoʻo ia i nā kikoʻī i hoʻonui ʻia nonstandard no nā laʻana e hiki mai ana, a me ka hiki ke hana paʻa a me ka lako wā lōʻihi.
