E koho i kahipahu wili nitridedno ka maʻemaʻe, non-abrasive resins e like me PP, PE, a me ABS - he emi ke kumu kūʻai a mau makahiki ma ia hana.

Ke hele nei kēia alakaʻi i ka ʻokoʻa metallurgical maoli ma waena o nā mea ʻelua, ka makemakika kumu kūʻai i mea nui (hint: ʻaʻole ia ke kumukūʻai sticker), a me kahi ala maʻalahi e hoʻoholo aipahu wiliwilikūpono i kāu mīkini, kāu mea, a me kāu kālā.
He aha ka Nitrided Screw Barrel?
A pahu wili nitridedhoʻomaka ma ke ʻano he ʻāpana kila hoʻokahi - aneane mau38CrMoAlAi loko o kā mākou hale kūʻai - a paʻa i ka ʻili i loko o kahi umu nitriding. Hoʻolaha ke kaʻina hana i ka nitrogen i loko o ka ʻili kila ma kahi mahana i mālama ʻia i nā hola he nui. ʻAʻohe mea ʻelua i hoʻohui ʻia. Hoʻoulu wale ke kila i kahi pūpū waho paʻakikī.
ʻO ka mea āu e hoʻopau ai he paʻakikī ʻili a puni ka HV 950–1000 a me kahi papa nitrided ma kahi o 0.5 a 0.7mm hohonu. ʻO kēlā ʻili ʻili lahilahi a paʻakikī hoʻi e haʻalele i ka abrasion mai nā polymers maʻamau a mālama i ka pahu i ke ʻano paʻa, holo ma hope o ka holo. ʻO nā barela Nitrided ka ʻoihana paʻamau no nā makahiki he nui, a no ke kumu maikaʻi: waiwai, wānana, a ʻoi aku ka nui o nā resins non-abrasive, non-corrosive e like me PP, PE, a me ABS.
He hohonu ka hopu. I ka wā e komo ai kēlā papa liʻiliʻi-milimita - a ma ke kaʻina hana abrasive - e ʻike ʻia ke kila kumu palupalu ma lalo, a hoʻomaka ka ʻaʻahu e holo aku mai ou aku.
He aha ka Bimetallic Screw Barrel?
A bimetallic pahu wiliwililawe i ke ala kū'ē i ka pilikia hohonu. Ma kahi o ka hoʻopaʻakikī ʻana i hoʻokahi kila, hoʻohui ia i kahi huila hana kiʻekiʻe ma luna o kahi kumu paʻakikī. ʻO ka metala kumu - he kila hoʻolālā - lawe i ka ukana a mālama i ka paʻa o ka pahu. ʻO ka ʻaoʻao hana o loko he papa hoʻokaʻawale ʻokoʻa, maʻamau ka nickel-based a i ʻole tungsten-carbide-based, i hoʻopaʻa ʻia i ke kumu ma o ka hoʻolei ʻana centrifugal. Hoʻopaʻa ʻia nā metala ʻelua i hoʻokahi ʻāpana.
Eia ka mea i ʻokoʻa ai: holo ka papa pale i 2.0 a 3.0mm ka hohonu, ma ka paʻakikī o HRC 60–65. E hoʻonoho i kēlā ma kahi kokoke i ka ʻili hapalua millimeter ma kahi pahu nitrided a komo ke kiko holoʻokoʻa. Hoʻolaha ʻia ke kūpaʻa ʻana ma kahi ʻāpana ʻoi aku ka mānoanoa, no laila e paʻa loa ka pahu i kona geometry i ka wā e hakakā ana i ka abrasion a i ʻole ka ʻino. ʻO ka pulupulu aniani, nā mea hoʻopiha mineral, nā pūhui halogen - nā mea e nahu ai i ka ʻili nitrided - kahi i loaʻa ai i kahi papa bimetallic kona mālama.
ʻAʻole like nā papa bimetallic a pau. Ke hilinaʻi nei kahi huila nickel i ka pale ʻana i ka corrosion - ke koho kūpono no ka PVC a me nā mea pale ahi. ʻO kahi papa waiwai tungsten-carbide e hilinaʻi ana i ke kūpaʻa abrasion maka, ʻo ia ka mea e koi ai i ka fiber glass-fiber a me nā pūhui mineral kiʻekiʻe. Noho nā mea hao i waena ma ke ʻano he kumu kūʻai. ʻO ka hoʻohālikelike ʻana i ka alloy i ka ʻenemi kikoʻī - corrosion a abrasion - mea nui e like me ke koho ʻana i ka bimetallic ma kahi mua.

E hoʻopaʻa i nā noi hoʻopaʻi maoli - PVC piha piha, nā pūhui i hoʻoikaika ʻia i ke aniani - a hoʻonui hou ʻia ke āpau. Aia kekahi kihi ʻino: i ka wā e hana ai ʻoe i nā resins PVC a i ʻole flame-retardant resins, hoʻokuʻu ka mea i nā pūhui e hoʻouka kemika i kahi ʻili nitrided. ʻAʻole mālama wale ka papa nickel-based bimetallic.
ʻO ka manawa e koho ai i kahi Barela Screw Nitrided
A pahu wili nitridedʻoi aku ka nui o ke kelepona kūpono ma mua o ka ʻae ʻana o ka mea kūʻai aku. Holo maʻemaʻe, unfilled thermoplastics - puʻupaʻa PP, PE, PS, ABS - me ke aniani fiber, ʻaʻohe mineral filler, ʻaʻohe corrosive additives, a ʻo kēlā ʻāpana nitrided lahilahi e hāʻawi iā ʻoe i nā makahiki o ka lawelawe kūpaʻa ma ke kumu kūʻai haʻahaʻa.
Maikaʻi nō hoʻi i ka wā e paʻa ai ka waihona kālā, i ka wā e holo ai ka mīkini a hoʻomaka ma mua o ka puni ʻana o ka uaki, a i ʻole ke hoʻonohonoho ʻana i kahi laina e loli paha ka hui ʻana ma mua o ka pau ʻana o ka pahu.

ʻO ka manawa e koho ai i kahi pahu pahu bimetallic
ʻO ka manawa abrasion a corrosion e komo i ke kiʻi, abimetallic pahu wiliwililoaʻa i kona kumukūʻai kiʻekiʻe.

Ka Hoʻohālikelike Kūʻai: Kumukūʻai mua vs ka huina kālā o ka ʻona
ʻO ka instinct e hoʻohālikelike i nā kumukūʻai sticker ʻo ia ka mea e alakaʻi ai i nā hoʻoholo barrel screw maikaʻi ʻole. Lanakila ka pahu nitrided i ka lā hoʻokahi. Abimetallic pahu wiliwililanakila maʻamau ma luna o ke ola o ka mīkini - akā ma ka noi kūpono wale nō.
No laila e holo i ka helu ʻē aʻe: ka huina kālā o ka ʻona. Pono e hoʻololi ʻia kahi pahu nitrided i loko o ka hana abrasive i loko o 12 a 18 mau mahina, a ʻo kēlā me kēia pani e kauo ʻia me ka hana hoʻopau, nalowale ka hana, a me ka ʻōpala hoʻomaka ma luna o ke kumu kūʻai. Hiki i ka pahu bimetallic ma ia kaʻina hana ke holo i nā manawa he nui, e hoʻolaha ana i kona kumukūʻai kiʻekiʻe ma mua o nā hola hana. ʻOi aku ke kumu kūʻai mua, haʻahaʻa ke kumu kūʻai ola.
ʻĀnō e hoʻohuli. E kau i ka barela bimetallic ma kahi laina PE maʻemaʻe a ʻaʻole loaʻa ka manawa e uku ai iā ia iho - lanakila ka pahu nitrided ma ke kumu kūʻai a me ke kumu kūʻai o ke ola, no ka mea, ʻaʻohe mea i loko o ia kaʻina e hoʻoikaika i ka alloy. Loko like, pane kū'ē. Hoʻoholo ka mea.
