ʻO Dacromet Hex Head Self-Drilling Screw

1. Nā māla kūpono a me nā kūlana huahana

Hana ʻia kēia huahana e like me nā kikoʻī kikoʻī drill point drill maʻamau Kina. Loaʻa iā ia he flange hex + i hoʻohui ʻia i ka hoʻoheheʻe ʻana i ka pahu wai. Hoʻohana nui ʻia ia no ka hoʻopaʻa ʻana i nā hale i waho o nā wahi corrosive loa. Hoʻohana nui ʻia ia i nā hale hana kila, nā hale kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi, nā papahana kila kala kahakai, nā pā waho, a me nā mea hoʻonoho pā pale anti-corrosion. Hoʻokuʻu ʻia ia i ka Middle East, Hikina Hema ʻo Asia, a me nā hale kūʻai hale kūʻai ʻē aʻe ma kahakai i nā ʻāpana a puni ka makahiki. He kūpono ʻo Dacromet anti-corrosion no ka saline-alkali o ka moana, ka haʻahaʻa a me ka ua, a ua kūpono ke kumu lōʻihi no nā panels insulation sandwich a me ka hui superposition superposition kala kala. Hoʻopau ia i ka pono no ka pre-drilling a hoʻopōkole loa i ka wā kūkulu waho.

2. Nā mea maka a me nā kaʻina hana

ʻO ka mea maka he kila kalapona kiʻekiʻe, a hoʻohana ʻia ka mālama wela hoʻopau holoʻokoʻa. ʻO ka paʻakikī o ka ʻoki ʻoki ʻana i ka drill a hiki i ka maʻamau, a ʻo ka wili ʻana o nā ʻāpana kila mānoanoa ke kūpaʻa i ka ʻoki ʻana a i ʻole ka haki ʻana ma ka wahi drill. Kaʻina hana: Kaʻina hana: kaha kiʻi o nā mea maka, annealing, phosphating, kiʻi maikaʻi, ke poʻo anu, ka hoʻokumu ʻana i ke kiko, ka ʻōwili ʻana i ka milo, ka hoʻomaʻamaʻa ʻana i ka wela, Dacromet anti-corrosion coating, hui ʻana o ka mea holoi, hoʻopili, ʻumikūmākahi kaʻina, hoʻolālā niho ʻāpana, ʻeli iho i ka ʻāpana mua, paʻa paʻa ma ka ʻaoʻao hope, ʻaʻole maʻalahi ke koʻokoʻo ikaika; He paʻa ikaika ka uhi ʻana o Dacromet, ʻaʻohe pilikia hydrogen embrittlement, ʻoi aku ka pale ʻana o ka paʻakai ma mua o nā huahana zinc plated maʻamau.

3. Nā pono kumu waiwai

ʻO ka anti-corrosion no ka wā lōʻihi o Dacromet: ʻOi aku ka paʻakai a kū i ka waika, alkali a me ka paʻakai paʻakai. Hiki iā ia ke hāʻawi i ka anti-rust no ka wā lōʻihi ma kahakai, nā wahi mea kanu kemika a me ka ua ākea ākea, e hoʻopau ana i ka pōʻino huna o ka ʻōpala a me ka leaka wai.

Hoʻohui ʻia ke sila wai ʻole: EPDM rubber bonded washer apo ke kūpaʻa i nā kukuna ultraviolet a me ka ʻelemakule, a ʻaʻole e pohā ke ʻike ʻia i ka lā no ka manawa lōʻihi. Ma hope o ka hoʻopaʻa ʻana, hoʻopaʻa paʻa ʻia nā puka wili i mea e pale aku ai i ka wai o ka hale mai ke kumu.

ʻO ke ʻano o ke kaula ʻāpana i hoʻonui ʻia: He kūpono ke kumu lōʻihi no nā papa ʻāpana he nui e like me ka huluhulu pōhaku a me nā panela sandwich polyurethane. ʻAʻole nā ​​niho i hoʻokaʻawale ʻia i ka laka ʻana a me ka hoʻopaʻa ʻana i ke kila kala, a kūpono ia no ka hana ʻana i ka hale insulation multi-thickness.

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

Loaʻa nā moʻo kikoʻī kikoʻī āpau, hoʻouna ʻia nā kauoha maʻamau i loko o 48 mau hola, a hiki ke ʻae ʻia ke kālepa haole piha piha a me nā kauoha nui no nā papahana ʻenekinia. ʻO ka paʻakikī o ka drill point, ka mānoanoa o ka uhi ʻana o Dacromet, ka ikaika hoʻopaʻa paʻa paʻa, a me ka pololei o ke kaula e nānā ʻia i kēlā me kēia mea ma mua o ka haʻalele ʻana i ka hale hana, a ua hoʻopau ʻia nā huahana kīnā ʻole me ka uhi ʻana a me nā ʻōlelo aʻoaʻo drill pōʻino. Hiki ke hoʻolako ʻia i nā pūʻulu piha me ka wahi hoʻoheheʻe hexagonal pōkole o ka hale hana a me ka countersunk head drill point, a me kahi pahu hoʻopaʻa hale hoʻokahi; Kākoʻo ʻo ia i nā wili hoʻolāʻihi kūikawā kūikawā, nonstandard pitch self-drilling screws, a me ka hiki ke hana paʻa e hōʻoia i ka lako no ka wā lōʻihi no nā papahana ʻoihana nui.
