Hex Head No. 5 Point Self-Drilling Screw

1. Nā kahua pili

Hoʻohana nui ʻia nā moena ʻeleʻele ʻeleʻele EPDM no nā hale hao kala hāmama, nā papahele hale hana, a me nā pā waho, a he wai wai a anti-seepage; Hoʻohana nui ʻia nā moena PVC alohilohi no nā keels kila māmā o loko, nā pani puka puka a me nā puka makani, a me ka hui ʻana o ka hao electromechanical. Hoʻokahi wili he ʻelua kumu e uhi ai i nā hiʻohiʻona hoʻopaʻa ʻana o ka panel lahilahi a me waho. He mea hoʻopaʻa paʻa honua no nā hale kila kīwila a me ka hoʻonani hale. Ua lawe lōʻihi ʻia i ka Hikina Hema ʻo Asia a me ka Middle East hardware and building materials market. Hele mai ia me kahi ʻano drill point, e hoʻopau ana i ka pono o nā lua pre-drilling, kahi e hoʻomaikaʻi nui ai i ke kūkulu ʻana.

2. Nā mea maka a me nā kaʻina hana

Koho ʻia ke kila kalapona kiʻekiʻe 22A, a ua hoʻoikaika ʻia ke kinai ʻana o ka ʻāpana drill point. He ʻoi ka lua drill a kū i ka ʻoki ʻana ma ka wēlau a me ka haki ʻana ma ka wahi drill. He ʻumikūmākahi kaʻina hana e pili ana i ke kaha kiʻi ʻana o nā mea maka - annealing, phosphating, kiʻi maikaʻi, ke poʻo anuanu, ka hana ʻana o ka huelo, ka ʻōwili ʻana o ka wili, ka hoʻololi ʻana i ka wela a me ka hana ʻana, ka polū-keʻokeʻo zinc plated electroplating, ka hui holoi holoi, a me ka hoʻopili. Maʻemaʻe ka maka hex flange, a paʻa pono ke kī kī me ka paheʻe ʻole; ua piha nā kaula a pili pono; ua kūpono nā ʻano ʻelua o nā ʻōpala no nā kūlana hana like ʻole i ka lewa ākea a i loko o ka hale, a paʻa paʻa a ʻaʻole maʻalahi e hāʻule.

3. Nā pono kumu waiwai

Hiki ke koho ʻia nā pāpaʻi pālua ʻelua e like me ka mea e pono ai: ʻeleʻele ʻo EPDM rubber he UV-resistant, anti-aging, sila a me ka wai ʻole ke ʻike ʻia i ka ua ma ka lewa; He māmā nā pāpaʻi PVC a ʻoi aku ka maikaʻi ma nā wahi maloʻo o loko.

Ua piha nā niho o ke kino a me ka ikaika paʻa paʻa: ua uhi ʻia ke koʻokoʻo holoʻokoʻa i nā kaula, a paʻa paʻa ka ʻili hao a me ke kile kila, e paʻakikī ke wehe a hāʻule i lalo o ka makani ikaika a me nā kūlana haʻalulu.

ʻOi aku ka ʻeleʻele polū-keʻokeʻo zinc a hiki ke hoʻokaʻawale i ka mahu wai. He kūpono no ka hoʻohana ʻana i loko a me waho. I loko o ke kahakai kiʻekiʻe-humidity a me ka corrosive kaiapuni, hiki ke hoʻonui ʻia i Dacromet coating.

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

ʻO ka piha piha o nā kiko'ī i nā manawa a pau, hoʻounaʻia nā kauoha maʻamau i loko o nā hola 48, a loaʻa nā kauoha no nā kauoha liʻiliʻi liʻiliʻi a me ka laweʻana i ka pahu piha. ʻO ka paʻakikī o ka drill point, flange flatness, ka ikaika pipili o ka pad rubber, a me ka maikaʻi o ka uhi ʻana ke nānā ʻia ma mua o ka haʻalele ʻana i ka hale hana, a ua hoʻopau ʻia nā huahana kīnā ʻole me nā wili kuʻo, ke poho kelu, a me nā pale kīnā. Hiki ke hoʻolako ʻia me nā poʻo nylon spray-painted drill points a me ka sandwich panel extended drill points no ka waiwai piha; Kākoʻo ia i nā huahana i hoʻopilikino ʻia me nā lōʻihi kūikawā a me nā ʻaʻahu nonstandard, a hiki ke hoʻolako paʻa i ka lako no ka wā lōʻihi no nā hana kūkulu like ʻole.
