DTPD CAS 68953-84-4
Antioxidant DTPD nthawi zambiri imakhala yofiirira ngati imvi yokhala ndi kachulukidwe ka pafupifupi 1.2 (pa 20℃). Pa 20℃, kusungunuka kwake mu zinthu zosungunulira zachilengedwe ndi 5.39-12.09g/L, kusungunuka kwake m'madzi ndi 45-130μg/L, ndipo LogP yake ndi 3.3-4.6. Acidity coefficient (pKa) ndi 1.4-1.47 pa 20℃.

1. Chitetezo chapakati pa zinthu za rabara: choletsa kukalamba ndi nthawi yayitali yogwirira ntchito
Iyi ndiyo ntchito yake yaikulu, kupereka chitetezo chofunikira ku mavuto okalamba a mphira omwe amayamba chifukwa cha "kutentha, ozoni, ndi okosijeni" panthawi yogwiritsidwa ntchito (monga kuuma, kusweka, ndi kuchepa kwa kusinthasintha).
Kupanga matayala: Amagwiritsidwa ntchito mu zinthu zopondaponda ndi zogwirira ntchito za matayala osiyanasiyana monga magalimoto, malole, ndi makina omangira kuti ateteze kutentha komwe kumachitika chifukwa cha kukangana kwa magalimoto komanso kuwonongeka kwa ozone mumlengalenga, kuchedwetsa kukalamba ndi kusweka kwa matayala, ndikuwonjezera nthawi yawo yogwirira ntchito.
Zinthu zopangidwa ndi rabara m'mafakitale: Zoyenera kugwiritsa ntchito mapaipi a rabara (monga mapaipi amafuta ndi gasi), malamba otumizira katundu (ogwirira ntchito zamigodi ndi zoyendera), ndi zomatira (ma O-rings, ma gasket), kuti zinthuzi zisakalamba msanga komanso kulephera kugwira ntchito zikagwiritsidwa ntchito panja kapena pamalo ovuta (monga kutentha kwambiri ndi chinyezi) kwa nthawi yayitali.
Zinthu za rabara zomwe zimagwiritsidwa ntchito tsiku ndi tsiku/zapadera: zomwe zimagwiritsidwa ntchito popanga zingwe za rabara zopukutira, ma gasket a rabara, rabara yoyamwa shock (ya magalimoto/makina), komanso zinthu zopangidwa ndi rabara yopangidwa monga rabara ya chloroprene ndi rabara ya styrene-butadiene, zomwe zimasunga kusinthasintha kwawo kwa nthawi yayitali komanso magwiridwe antchito akagwiritsidwa ntchito.
2. Zothandizira zoteteza rabara pazochitika zinazake
Kuwonjezera pa chitetezo cha anthu onse, mavuto enaake okalamba angathenso kuthetsedwa makamaka potengera momwe zinthu za rabara zimagwiritsidwira ntchito:
Kukalamba koletsa kutopa: Kumagwiritsidwa ntchito pa zinthu za rabara zomwe zimafunika kuchitidwa zinthu zomwe zimafunika kuchitidwa zinthu zomwe zimafuna mphamvu zambiri (monga ma conveyor lamba ndi ma shock absorbers), kuchepetsa "kusweka kwa kutopa" komwe kumachitika chifukwa cha kupsinjika kwamphamvu komanso okosijeni.
Chithandizo choteteza kutentha kwambiri: Mu zinthu za rabara zomwe zimagwiritsidwa ntchito m'malo otentha apakati komanso apamwamba (monga zomangira za injini), zikaphatikizidwa ndi ma antioxidants ena, zimawonjezera kukana kutentha kwa rabara ndikuletsa kuti isaume mwachangu ndikusweka ikatentha kwambiri.
1. Chiyero ≥ 99.99%, choposa muyezo wamakampani a batri;
2. Chinyezi ≤50 ppm, kutchinjiriza kwake kumakhala bwino kwambiri;
3.Kukhazikika kwabwino kwambiri kwa kutentha
