NBR vs FKM Rubber in Rubber coated metala mea: He Comparative Analysis

He mea koʻikoʻi ka hoʻopaʻa ʻana i nā ʻoihana like ʻole, e hōʻoia ana i ka paʻa ʻana o nā wai a me nā kinoea a e holo pono nā ʻōnaehana.ʻElua mau mea hao kaulana i hoʻohana ʻia i loko o ka pepa metala i uhi ʻia i ka lāʻau ʻo NBR (Nitrile Butadiene Rubber) a me FKM (Fluorocarbon Rubber).ʻOiai hāʻawi nā mea ʻelua i nā waiwai sealing maikaʻi loa, loaʻa iā lākou nā hiʻohiʻona ʻokoʻa i kūpono iā lākou no nā noi like ʻole.Ma kēia ʻatikala, e ʻimi mākou i nā mea like a me nā ʻokoʻa ma waena o NBR a me FKM rubber ma ka pōʻaiapili o nā papa i uhi ʻia.

Kaʻana like ʻo NBR a me FKM i kekahi mau hiʻohiʻona maʻamau e waiwai ai lākou i ka hoʻopaʻa ʻana i nā noi:

Palekana Kemika: Hōʻike nā lāʻau ʻelua i ke kūpaʻa maikaʻi loa i kahi ākea o nā kemika, nā aila, a me nā solvents.He mea koʻikoʻi kēia hiʻohiʻona no ka hōʻoia ʻana e hiki i nā papa i uhi ʻia i ka sila ke kū i ka media koʻikoʻi a lākou e hālāwai ai.

Kū'ē Kūlana: Hiki i nā ʻōpala NBR a me FKM ke hana i loko o kahi ākea ākea, e hoʻolilo iā lākou i mea maʻalahi no nā kūlana kaiapuni.Hiki iā lākou ke pale i nā mahana haʻahaʻa a me ke kiʻekiʻe, e hōʻoiaʻiʻo ana i ka hana sealing hilinaʻi.

ʻOiai ko lākou ʻano like, loaʻa nā waiwai ʻokoʻa o ka NBR a me ka FKM rubber i kūpono iā lākou no nā hiʻohiʻona like ʻole:

NBR Rubber:

ʻAila Kūʻē: Kaulana ʻo NBR no kona kūpaʻa ʻana i ka aila maikaʻi, ʻoi aku ka kūʻē ʻana i nā aila mineral a me nā aila wahie.He koho kūpono kēia no nā noi kahi e manaʻo ʻia ai ka pili ʻana me kēia mau ʻano aila.

Kū'ē wela: ʻOiai hāʻawi ʻo NBR i ke kūpaʻa wela maikaʻi, hiki ke hoʻohaʻahaʻa i ka manawa ke ʻike ʻia i nā wela kiʻekiʻe.No laila, ʻoi aku ka maikaʻi no nā noi me nā koi wela haʻahaʻa.

Uku Uku: He emi ke kumu kūʻai o ka NBR ma mua o FKM, e lilo ana ia i koho kaulana no nā papahana koʻikoʻi ke kumu kūʻai ʻoiai e hāʻawi mau ana i ka hana ʻoluʻolu.

Kū'ē Kūʻokoʻa: ʻOi aku ka ʻilihune o ka NBR i ka hoʻohālikelike ʻia me FKM, ʻoi aku ka nui ma nā wahi wela a me ka oxidative, hiki ke kaupalena i kona lōʻihi i kekahi mau noi.

FKM Rubber:

Palekana Kemika: Hāʻawi ʻo FKM rubber i ke kūʻē kūʻokoʻa i nā ʻakika ikaika, nā kumu, a me nā oxidizers, e lilo ia i mea koho maikaʻi loa no nā noi e pili ana i nā kemika ikaika.

Kū'ē wela: ʻoi aku ka maikaʻi o FKM i nā kaiapuni wela kiʻekiʻe, e mālama ana i kona kūpaʻa a me ka hoʻopaʻa ʻana i nā waiwai a hiki i nā wela kiʻekiʻe, a hiki i 150 degere Celsius.

Kū'ē Kū'ē: Hōʻike ka FKM i ke kūpaʻa ʻelemakule maikaʻi loa, e hōʻoia ana i ka lōʻihi lōʻihi a me ka hilinaʻi i nā kūlana koʻikoʻi.

Kumukūʻai: ʻOi aku ka nui o ka FKM ma mua o ka NBR, akā ʻo kāna hana maikaʻi e hōʻoia i kona hoʻohana ʻana i nā noi koʻikoʻi a koi.

Ke koho ʻana i nā mea kūpono no nā pā i uhi ʻia i ka Sealant:

I ke koho ʻana ma waena o NBR a me FKM no nā papa i uhi ʻia i ka sealant, pono e noʻonoʻo ʻia nā kumu aʻe:

E hoʻoholo i ke ʻano o ka wai a i ʻole ke kinoea e hālāwai ai ka mea hoʻopaʻa.Ua kūpono ʻo NBR no nā ʻaila mineral, ʻoiai ʻo FKM ka mea i makemake ʻia no nā kemika koʻikoʻi.

Nā Koina Mahana: E loiloi i nā kūlana wela o ka noi.ʻOi aku ka maikaʻi o FKM no nā kaiapuni wela kiʻekiʻe, ʻoiai ʻoi aku ka maikaʻi o ka NBR no nā mahana haʻahaʻa.

Noʻonoʻo Kūʻai: E loiloi i ka waihona kālā o ka papahana.Hāʻawi ʻo NBR i kahi hopena kumu kūʻai me ka ʻole o ka hoʻokō ʻana i ka hana, ʻoiai hāʻawi ʻo FKM i ka hana ʻoi aku ka maikaʻi ma ke kumukūʻai kiʻekiʻe.

NBR a me FKM rubbers ua loaʻa ko lākou wahi i loko o ka honua o ka rubber coated metala.ʻO ka hoʻomaopopo ʻana i kā lākou mau like a me nā ʻokoʻa e hiki ai i nā ʻenekinia a me nā mea hoʻolālā ke hoʻoholo i ka ʻike e pili ana i nā koi kikoʻī o kā lākou noi.Ma ka noʻonoʻo ʻana i nā mea e like me ke ʻano o ka media, ka mahana, a me ke kumukūʻai, hiki ke koho ʻia ke ʻano o ka lāʻau lapaʻau kūpono e hōʻoia i ka sila hilinaʻi a me ka hana maikaʻi loa i nā ʻoihana like ʻole.
