Ka hopena hoʻololi o PTFE ma ka ʻoihana Valve: Hoʻonui i ka hana, ke kūpaʻa, a me ka palekana

1. Hoʻolauna:PTFEma ke ʻano he mea hoʻololi pāʻani ma ka ʻenehana Valve

He mau ʻāpana koʻikoʻi nā valves i nā ʻōnaehana hoʻomalu wai, kahi e pili pololei ai ka hana i ka palekana, ka pono, a me nā kumukūʻai hana. ʻOiai ʻo nā metala e like me ke kila kila a i ʻole nā ​​​​alloys i hoʻomalu mau i ke kūkulu ʻana o ka valve, hakakā lākou me ka pala, ka ʻaʻahu, a me ka mālama nui ʻana i nā wahi hoʻonāukiuki.Polytetrafluoroethylene (PTFE), kahi fluoropolymer hana kiʻekiʻe, ua wehewehe hou i ka hoʻolālā valve ma ka hoʻoponopono ʻana i kēia mau palena. ʻO kona mau waiwai kū hoʻokahi—ka inertness kemika, ke kūpaʻa o ka mahana, a me ka lubrication ponoʻī—hiki i nā valves ke hana hilinaʻi i nā noi corrosive, kiʻekiʻe-maʻemaʻe, a i ʻole nā ​​​​​​mea wela loa. Ke noiʻi nei kēia ʻatikala pehea e hoʻomaikaʻi ai ka PTFE i ka hana valve ma nā ʻoihana, mai ka hana kemika a i nā lāʻau lapaʻau, a me kāna kuleana i ka hoʻokele ʻana i ka hana hou i nā ʻenehana sila a me ka ʻepekema mea.

2. Pehea e hoʻoponopono ai ʻo PTFE i nā pilikia valve koʻikoʻi

ʻO ke ʻano molekala o PTFE, i hōʻike ʻia e nā pilina kalapona-fluorine ikaika, hāʻawi i kahi hui o nā waiwai e lanakila ai i nā hemahema valve maʻamau:

ʻO ka Inertness Chemical: Kūʻē ʻo PTFE i nā mea hoʻonāukiuki āpau, me nā waikawa ikaika (e laʻa, ka waikawa sulfuric), nā alkalis, a me nā mea hoʻoheheʻe organik. Hoʻopau kēia i nā leaka i hoʻoulu ʻia e ka corrosion, kahi pilikia pinepine i nā valves metala.

Ka Hoʻomanawanui Mahana Laulā: Me kahi pae hana o -200°C a i +260°C, mālama ka PTFE i ka maʻalahi i nā noi cryogenic a me ke kūpaʻa i ka mahu wela kiʻekiʻe, e hōʻemi ana i ka hāʻule ʻana o ka valve i ka paikikala thermal.

ʻO ka ʻili haʻahaʻa haʻahaʻa a me ka ʻili ʻaʻole e pipili: ʻO ke koina haʻalulu o PTFE (~ 0.04) e hōʻemi i ka torque actuation a pale i ka hōʻiliʻili ʻana o nā mea (e laʻa, polymers a i ʻole nā ​​​​crystals), e hōʻoiaʻiʻo ana i ka hana maʻalahi i nā media viscous a slurry paha.

ʻAʻohe haumia: Ma ke ʻano he mea maʻemaʻe, ua hoʻokō ʻo PTFE i nā kūlana maʻemaʻe no nā lāʻau lapaʻau a me ka hana ʻana i ka meaʻai, e pale ana i ka haumia o ka huahana.

ʻAe kēia mau hiʻohiʻona iā PTFE e hoʻolōʻihi i ke ola o ka valve ma 3-5 mau manawa i hoʻohālikelike ʻia me nā mea maʻamau, me ka hoʻemi ʻana i ka alapine (frequency) o ka mālama ʻana a me ka downtime.

3. Nā Hana Hou Koʻikoʻi i nā ʻĀpana Valve PTFE

3.1 Nā ʻōnaehana sila holomua

Hoʻololi ka PTFE i ka sila ʻana o ka valve ma o nā hoʻolālā e uku no nā loli o ke komo ʻana a me ke kaomi:

Nā Hoʻopihapiha PTFE Conical: Ke pani nei i nā ʻeke ʻano V kuʻuna, hāʻawi nā mea hoʻopihapiha PTFE conical me ka hoʻoikaika kila kila i ke kaomi sila ponoʻī. Ma lalo o ke kaomi kūloko, hoʻopaʻa ikaika ka hoʻolālā conical, e pale ana i nā leaka i nā noi pōʻaiapuni kiʻekiʻe.

Nā Puʻu PTFE-Graphite Multi-Layer: I loko o nā kumu valve, mālama nā papa PTFE-graphite composites i hoʻopaʻa ʻia i ka pono o ke sila ma lalo o nā loli o ka mahana. Hōʻoia nā papa PTFE i ke kūpaʻa kemika, ʻoiai ʻo ka graphite e hoʻonui i ka conductivity thermal, e hōʻemi ana i ka haki ʻana o ke kaumaha.

3.2 Nā Kino Valve i Laina ʻia

No ka pale piha ʻana i ka pilina wai, hoʻohana nā valves i ka PTFE lining—he papa 2-5 mm i hoʻopaʻa ʻia i nā kino valve metala. Hoʻokaʻawale kēia ʻano hana i nā mea ʻino mai nā ʻili metala, he mea nui ia no ka lawelawe ʻana i ka waikawa hydrochloric a i ʻole nā ​​​​​​mea hoʻonā chlorine. ʻO nā ʻano hana lining hou, e like me ke kālai ʻana isostatic, e hōʻoia i ka uhi like ʻole me ka ʻole o nā hakahaka, he mea nui ia no ka pale ʻana i ka palaho kūloko.

3.3 Nā mea kūloko i uhi ʻia me ka PTFE

ʻO nā ʻāpana e like me nā pōpō, nā disc, a i ʻole nā ​​​​diaphragms i uhi ʻia me PTFE e hoʻohui i ka ikaika kūkulu o ka metala me ke kūpaʻa ʻana i ka fluoropolymer corrosion. No ka laʻana, i loko o nā valves pōpō, loaʻa i nā pōpō i uhi ʻia e PTFE ka sila paʻa pehu (ISO 5208 Class VI) me ke kūʻē ʻana i ka corrosion galvanic.

4. Hoʻohālikelike Hana: Nā Kiwikā PTFE vs. Nā Kiwikā Kuʻuna

5. Ka hopena o nā hoʻonā PTFE Valve ma ka ʻoihana holoʻokoʻa

Ka Hana Kemika: Hoʻemi nā kiwikā poepoe i hoʻopaʻa ʻia me ka PTFE i loko o nā paipu waikawa sulfuric i nā hanana leakage kokoke i ka ʻole, he mea koʻikoʻi ia no ka hoʻokō ʻana i nā kūlana palekana o ke kaiapuni.

Nā lāʻau lapaʻau: ʻO nā diaphragms PTFE i loko o nā valves sterile e pale aku i ka hoʻopili microbial, he mea nui ia no ka mālama ʻana i nā lula GMP a me FDA.

Ka Ikehu a me ka Wai Lapaʻau: ʻO nā kiwikā pepeke i hoʻopaʻa ʻia me ka PTFE i loko o nā ʻōnaehana hoʻoluʻu e kūʻē i ka scaling a me ka hōʻike ʻana i ka chlorine, kahi e hōʻemi ai i ka nalowale o ka ikehu mai ke kū'ē ʻana i ke kahe ʻana ma 30%.

Hana ʻana o ka Semiconductor: Pale aku nā ʻāpana PTFE kiʻekiʻe i ka haumia ionic i loko o nā ʻōnaehana lawe wai a me ke kinoea maʻemaʻe loa.

6. Nā ʻAno Hou: Hoʻohui ʻana o ka PTFE Akamai a me ke Kūpaʻa

Ke hoʻomau nei ka hana a PTFE i ka ulu ʻana me nā koi o ka ʻoihana:

Nā Hoʻohuihui PTFE Hoʻomau: Mālama nā composites PTFE hana hou i ka 90% o ka hana pono o nā mea puʻupaʻa ʻoiai e hoʻemi ana i ka kapuaʻi o ke kaiapuni.

Nā Valves i hoʻokomo ʻia i loko o nā sila PTFE e nānā i ka ʻaʻahu a me ka leakage i ka manawa maoli, e hiki ai ke mālama wānana a hoʻemi i ka downtime i hoʻolālā ʻole ʻia.

Nā Mea Hana Hoʻohui: Hoʻohui nā hui PTFE-PEEK no nā kūlana koʻikoʻi (e laʻa me nā valves nukelea) i ka lubrication me ka paʻa mechanical, kahi e hoʻokuke ana i nā palena o ke kaomi a me nā palena mahana.

7. Hopena

Ua hoʻokiʻekiʻe nui ʻo PTFE i ka ʻenehana valve ma o ka hoʻoponopono ʻana i nā pilikia lōʻihi i ka pala, ka friction, a me ka hoʻokele mahana. ʻO kona hoʻohui ʻana i loko o nā sila, nā lining, a me nā uhi ʻāpana e hōʻoiaʻiʻo ana i ka hilinaʻi ma nā ʻoihana like ʻole, mai nā mea kanu kemika a i nā fabs semiconductor. I ka holomua ʻana o ka ʻepekema mea, e hoʻomau ka PTFE i ka hiki ke hoʻohana i nā hopena valve māmā, ʻoi aku ka maikaʻi, a lōʻihi ka lōʻihi e kūlike ana me nā ʻano honua i ka hoʻomau a me ka digitalization.

Hoʻohana ʻo Ningbo Yokey Precision Technology i ka ʻike loea PTFE compounding e hoʻomohala i nā sila maʻamau a me nā ʻāpana valve no nā kaʻa, ikehu, a me nā noi ʻoihana. ʻO kā mākou palapala hōʻoia IATF 16949 a me ISO 14001 e hōʻoiaʻiʻo i ka maikaʻi mau i nā wahi koʻikoʻi.

Nā huaʻōlelo: nā kiwikā PTFE, ka sila ʻana o ka fluoropolymer, ke kūpaʻa kemika, ka mana wai ʻoihana
