Ti-Resin ta Phenolic ta Premium: Ti-Polymer ta Thermosetting leti tirhisiwaka hi tindlela to hambana-hambana ta Switirhisiwa swa Matirhelo ya le Henhla
Tinsimu Letikulu ta Xikombelo
1. Switirhisiwa swa Nkoka eka Vumaki bya Tiindasitiri
Ti phenolic resins ti xiximiwa hikokwalaho ka vuswikoti bya tona byo endla swivumbeko swo tiya, leswi tiyeke hi dimensionally ehansi ka kuhisa na ntshikelelo:
Swihlanganisi na Tilaminate:
Aerospace: Yi tirhisiwa eka tiphaneleni ta le ndzeni ka swihahampfhuka, swiphemu swa njhini, na ku sivela ku hisa hikwalaho ka ku humesiwa ka yona ka musi wa le hansi na ku lwisana na malangavi (xikombiso, ku landzelerisa FAR 25.853 eka swihahampfhuka swa mabindzu).
Marine: Eka swiphemu swa swikepe na decking, ti phenolic composites ti lwisana na ku tswongiwa ka mati na ku bola, ti tlula fiberglass ya ndhavuko eka tindzhawu ta mati ya munyu.
Ku Endliwa ka Foundry na Mold:
Novolac resins, leyi hlanganisiweke na hexamethylenetetramine, yitirhisiwa eka sand casting eka swiphemu swa njhini ya mimovha (xikombiso, tinhloko ta cylinder). Ku tiya ka tona ka mahiselo yale henhla switiyisisa ku tlheriseriwa ka xivumbeko lexi kongomeke eka mahiselo ya casting lawa ya tlulaka 1,500°C.
2. Vumaki bya swa Elektroniki na Gezi
Tibodo ta Swirhendzevutani leti Gandliweke (PCB): .
Resole resins i ya nkoka eka ti epoxy-phenolic laminates eka ti PCBs, leti nyikaka matimba yale henhla ya dielectric xikan’we naku tshamiseka ka dimensional eka switirhisiwa swa frequency yale henhla (xikombiso, switirhisiwa swa vuhlanganisi swa 5G).
Ku Hlayisa Gezi: .
Swiphemu swa phenolic leswi vumbiweke (xikombiso, swiphemu swa switchgear, ti terminal blocks) swinyika ku tiya ka kahle swinene ka arc xikan’we naku tiya ka mahiselo, leswi fikelelaka swipimelo swa UL 94 V-0 swa ku pfurha eka vuhlayiseki bya gezi.
3. Xiyenge xa Mimovha na Vutleketli
Swiphemu swa le hansi ka xihuku:
Phenolic resins yitirhisiwa eka ti clutch plates, ti brake pads, na swiphemu swa transmission hikokwalaho ka ku tiya ka tona eka kuhisa (kufika eka 250°C) xikan’we na ntshikelelo wa michini. Hi xikombiso, eka tifektri ta timovha ta le Yuropa, swilo leswi tirhisaka phenolic leswi tirhisaka ku hlangana swi hunguta ku nyamalala ka maburuku eka timovha leti tirhaka kahle.
Swihlanganisi swo vevuka:
Ti tiyisisiwa hi nghilazi kumbe carbon fibre, ti phenolic composites titirhisiwa eka ti cabins ta tilori nale ndzeni ka switimela ku hunguta ntiko loko kurikarhi ku hlayisiwa vutshembeki bya xivumbeko xikan’we na vuhlayiseki bya ndzilo (xikombiso, ku landzelerisa EN 45545-2 eka vutleketli bya swiporo).
4. Switirhisiwa swo Aka na ku Aka
Swifunengeto Leswi Nga Tirhiki Ndzilo:
Phenolic resins yi endliwe kuva ti intumescent paints leti andlalaka kuva ti endla protective char layer eka mahiselo yale henhla, leswi hlwela ku wa ka xivumbeko eka miako (xikombiso, ti skyscrapers ta mabindzu e Asia).
Tiphaneli ta Swisirhelelo: .
Phenolic foam, leyingana thermal conductivity ya 0.02 W/m·K, yitirhisiwa eka insulation ya vutshamo na ti indasitiri, yinyika ku tiya ka ndzilo ka xiyimo xale henhla loko ku pimanyisiwa na polyurethane foam.
Swinamarheti na Swipfalo:
Swinamarheti leswi simekiweke eka phenolic swihlanganisa mapulanga, nsimbi, na ti ceramics eka switirhisiwa swo aka (xikombiso, ti laminated beams eka tindlu ta modular), leswi nyikaka ku tiya ka nkarhi woleha xikan’we naku lwisana na ndzhongho.
5. Nhundzu ya Vatirhisi na Switirhisiwa swo Hlawuleka
Switirhisiwa swa Khixi na Swihambukelo:
Ti phenolic resins leti vumbiweke ti endla ti countertops leti tiyeke, leti nga hisiki, ti sink na swiphemu swa faucet. Vuandlalo bya tona lebyi nga riki na ti porous byi lwisana na swivati na tikhemikhali, leswi endlaka leswaku ti va letinene eka tikhixi ta mabindzu.
Switirhisiwa swa Abrasive:
Resole resins yi boha ti abrasive grains (xikombiso, aluminium oxide, silicon carbide) eka maphepha ya sandpapers, mavhilwa yo sila, na ti discs to tsema, leswi tiyisisaka matirhelo lawa ya nga cincekiki eka ku tirha hi mapulanga na ku endla tinsimbi.

Khwalithi & Ku landzelerisa
Ku Cinca-cinca ka Xivumbeko:
Swi nga cinciwa hi ku landza swivumbeko swo karhi:
Ku tiya ka kuhisa lokukulu: Mahiselo ya ku cinca ka nghilazi (Tg) kuya fika eka 300°C eka switirhisiwa swa aerospace.
Ku Humesiwa ka Musi wa le Hansi: Tigredi leti cinciweke ta tindhawu to hundzisela na ta le lwandle (xikombiso, IMO FTPC Part 1 compliant).
Swipimelo swa Vulawuri: .
Yi fikelela swipimelo swa UL, ASTM, na ISO 9001:2015. Ti grade ta ku khumbana ka swakudya (xikombiso, ti phenolic resins eka swikhomo swa switirhisiwa) ti fambisana na FDA 21 CFR 177.1020.
Tiyiseleka:
Yi humelerisiwa hiku tirhisa bio-based phenol derivatives (xikombiso, cashew nut shell liquid) eka swivumbeko swin’wana, leswi hungutaka ku titshega hi ti petrochemicals. Ku vuyiseriwa hi ku hisiwa hi ku vuyiseriwa ka eneji.
Ha Yini Hi Hlawula Ti- Phenolic Resins Ta Hina?
Kunga khathariseki leswaku u lava swihlanganisi leswi nga pfurhiki ndzilo swa swihaha-mpfhuka, switirhisiwa swa ku hlangana swa matirhelo ya le henhla swa mimovha, kumbe swilo swo pfalela leswi tiyeke swo aka, ti- phenolic resins ta hina ti tisa ku tshembheka loku nga ringanisiwiki na nchumu. Hi nseketelo wa xithekiniki wa misava hinkwayo na switirhisiwa swa vuhumelerisi eAmerika N’walungu, Yuropa, na Asia, hi nyika swintshuxo leswi lulamisiweke—ku suka eka ku hlanganisiwa ka novolac/resole ku ya eka tigiredi leti tiyisisiweke—ku fikelela swilaveko swo tika swa xikombelo xa wena.
Endla vumundzuku hi Premium Phenolic Resins—laha ku hisa, tikhemikhali, na ku tiya ka michini swi hlamuselaka hi vuntshwa matirhelo ya swilo.
