Ubi Ngwa Ndị Dị Mkpa
1. Ngwa Isi na Mmepụta Ụlọ Ọrụ
A na-ahụta resin phenolic dị ka ihe dị oke mma maka ikike ha nwere ịmepụta ihe owuwu siri ike, nke kwụsiri ike n'okpuru okpomọkụ na nrụgide:
Ngwakọta na laminate:
Igwe Ọdụ: A na-eji ya eme ihe n'ime panel dị n'ime ụgbọelu, ihe ndị dị na injin, na mkpuchi okpomọkụ n'ihi obere mwepụ anwụrụ ọkụ ha na iguzogide ire ọkụ (dịka ọmụmaatụ, iwu FAR 25.853 maka ụgbọelu azụmahịa).
Mmiri: N'ime ụgbọ mmiri na ihe ndị dị n'elu, ihe ndị mejupụtara phenolic na-eguzogide mmiri ịmịkọrọ na ire ere, na-arụ ọrụ karịa fiberglass ọdịnala na gburugburu mmiri nnu.
Ime ihe owuwu na ebu:
A na-eji resin Novolac, tinyere hexamethylenetetramine, eme ihe n'ịkpụ ájá maka akụkụ injin ụgbọala (dịka ọmụmaatụ, isi silinda). Nkwụsi ike okpomọkụ dị elu ha na-eme ka ebu pụta ìhè na okpomọkụ karịrị 1,500°C.
2. Ụlọ ọrụ Eletrọniki na Ụlọ Ọrụ Eletrọniki
Bọọdụ Sekit Ebipụtara (PCBs):
Resin Resole dị mkpa na laminates epoxy-phenolic na PCBs, na-enye ike dielectric dị elu na nkwụsi ike nha maka ngwa ugboro ugboro (dịka ọmụmaatụ, ngwa nkwukọrịta 5G).
Mkpuchi eletriki:
Akụkụ phenolic a kpụrụ akpụ (dịka ọmụmaatụ, ihe ndị dị na switchgear, terminal blọk) na-enye ezigbo nguzogide arc na nkwụsi ike okpomọkụ, na-emezu ụkpụrụ ọkụ UL 94 V-0 maka nchekwa eletriki.
3. Ngalaba Ụgbọala na Njem
Ihe ndị dị n'okpuru mkpuchi:
A na-eji resin phenolic eme ihe na efere clutch, pad brek, na akụkụ nnyefe n'ihi na ha na-eguzogide okpomọkụ (ruo 250°C) na nrụgide igwe. Dịka ọmụmaatụ, na ụlọ ọrụ ụgbọ ala Europe, ihe ndị e ji phenolic mee na-ebelata ịcha brek na ụgbọala ndị nwere arụmọrụ dị elu.
Ngwakọta dị fechaa:
A na-eji iko ma ọ bụ eriri carbon eme ka ọ sie ike, a na-eji ihe mejupụtara phenolic eme ihe n'ime ụlọ gwongworo na ime ụlọ ụgbọ okporo ígwè iji belata ibu ma na-echekwa iguzosi ike n'ezi ihe na nchekwa ọkụ (dịka ọmụmaatụ, EN 45545-2 maka njem ụgbọ okporo ígwè).
4. Ihe owuwu na ihe owuwu ụlọ
Mkpuchi na-egbochi ọkụ:
A na-emepụta resin phenolic ka ọ bụrụ agba ndị na-egbuke egbuke nke na-agbasa iji mepụta oyi akwa nchekwa na oke okpomọkụ, na-egbu oge mmebi ihe owuwu n'ụlọ (dịka ọmụmaatụ, ụlọ elu azụmahịa na Eshia).
Ogwe mkpuchi:
A na-eji ụfụfụ phenolic, nke nwere ike ime ka okpomọkụ dịkwuo elu nke 0.02 W/m·K, eme ihe n'ihe mkpuchi ụlọ na ụlọ ọrụ mmepụta ihe, na-enye ike ọkụ ka mma ma e jiri ya tụnyere ụfụfụ polyurethane.
Ngwakọta na ihe mkpuchi:
Ihe mmado nke dabere na phenolic na-ejikọta osisi, ígwè, na seramiiki n'ọrụ owuwu (dịka ọmụmaatụ, osisi ndị e ji laminate mee n'ime ụlọ modular), na-enye ogologo oge na iguzogide mmiri.
5. Ngwa Ngwaahịa Ndị Ahịa na Ngwa Pụrụ Iche
Ihe eji esi nri na ụlọ ịsa ahụ:
Resin phenolic a kpụchara akpụ na-emepụta ihe ndị siri ike, ndị na-anaghị ekpo ọkụ, na ihe ndị dị na faucet. Elu ha na-anaghị amị amị na-eguzogide ntụpọ na kemịkalụ, nke na-eme ka ha dị mma maka kichin azụmahịa.
Ngwaahịa Na-afụ ụfụ:
Resin Resole na-ejikọta mkpụrụ osisi abrasive (dịka ọmụmaatụ, aluminum oxide, silicon carbide) na akwụkwọ ájá, wiil igweri, na diski ịkpụ, na-eme ka arụmọrụ ya sie ike n'ịrụ ọrụ osisi na imepụta ígwè.
