Rubber active agent leyi tivekaka tani hi vulcanizing active agent. Nchumu lowu nga riki wa ntumbuluko kumbe wa organic lowu tirhisiwaka ku endla leswaku xihatlisisi xa vulcanization xi tirha. Swinga kurisa vuswikoti bya accelerator, swihunguta nhlayo ya accelerator, naku pfuxeta nkarhi wa vulcanization. Vunyingi bya swiengeteri leswi nga riki swa ntumbuluko i ti oxide ta nsimbi, ti hydroxides na ti carbonates ta xisekelo, ku fana na zinc oxide, lead oxide, calcium hydroxide, lead carbonate, na swin’wana, nchumu wa nkoka swinene eka ti organic additives i ti fatty acids, leti landzeriwaka hi ti amine, ti-amine, etc. Ndzilo wa rhaba.

Swiengeteri swa rhaba: Swihlawulekisi swa vuxokoxoko, swipfuno, na switirhisiwa .

Swinamarheti: Ku hlanganisiwa ka rhaba na nsimbi (ku engetela matimba ya peel hi 30–40%).

2. phenolic resin .

Miako:

Thermosetting polymer leyi nga na density ya le henhla ya crosslink.
Ku lwisana na kuhisa: Kutirhisiwa loku yaka emahlweni kuya fika eka 180°C (intermittent 250°C).
Ku tiya ka le henhla (modulus: 2–4 GPA) na ku tiya ka dimensional.
Ku lwisana na tikhemikhali eka ti acid, swisekelo, na swin’wetsin’wetsi.

Swipfuno:

Ku nyika ku tiyisisiwa ka xivumbeko (ku engetela ku tiya hi 10–20 wa ribuwa ra A).
Flame Retardant (UL94 V-0 rating handle ka swiengeteri swa halogen).
Ku tirha kahle loko ku pimanisiwa na ti thermoplastics to hlawuleka.
Tisisiteme to horisa leti nga cinciwaka (acid-catalyzed kumbe ku tirhisiwa hi ku hisa).

Swikombelo:

Mathayere: Swihlanganisi swa le tlhelo (swi antswisa ku lwisana loku tsemiweke, ASTM D624).
Mabandhi ya tiindasitiri: mabandhi yo fambisa eka tindzhawu ta mahiselo yale henhla (xikombiso, swimilani swa semende).
Switirhisiwa swa friction: Ti brake pads (ti hlayisa coefficient ya friction eka 0.35–0.45 ehansi ka 200°C).
Foundry: Core Sand Binders (yi hunguta ku cinca ka gasi hi nkarhi wa ku hoxa).

Muxaka wa misava hinkwayo wa xiyimo xa le henhla xa ku n’oka loku tacking phenolic resin .

Ku humelela: Ku vonakala ko tshwuka ku ya eka yellow granular
Global softening point: 105-110°C
Ash (600°C): ≤0.5%

hi ku landza swilaveko swa le henhla swa 10 hwelen phenolic. eChayina, hi malembe ya vutshila bya indasitiri. Hi nyika nxaxamelo wo anama wa muxaka wa misava hinkwayo wa le henhla wa melting point tackeing phenolic resins, leyi endleriweke ku fikelela swilaveko swa switirhisiwa swo hambana swa tiindasitiri. Hi nxavo wa mphikizano na matirhelo ya xiyimo xa le henhla, switirhisiwa swa hina swi endliwile ku tisa ku namarhela lokunene, ku tshamiseka, na ku tiya eka swilaveko swa wena swa vumaki. Tihlanganisi na hina sweswi ku kuma ndlela leyi swintshuxo swa hina swi nga seketelaka ku kula ka bindzu ra wena ha yona!
