Iyini i-DTPD CAS 68953-84-4?

I-Antioxidant DTPD ivame ukuba yinto eqinile empunga-nsundu enobukhulu obungaba ngu-1.2 (ku-20℃). Ku-20℃, ukuncibilika kwayo ezinyibilikisini eziphilayo kungu-5.39-12.09g/L, ukuncibilika kwayo emanzini kungu-45-130μg/L, kanti i-LogP yayo ingu-3.3-4.6. I-acidity coefficient (pKa) ingu-1.4-1.47 ku-20℃.

Isicelo

1. Ukuvikelwa okuyinhloko kwemikhiqizo yerabha: ukulwa nokuguga kanye nokuphila isikhathi eside kwenkonzo

Lokhu kuyindlela eyinhloko yokusebenzisa kwayo, ehlinzeka ngokuvikelwa okubalulekile ezinkingeni zokuguga zerabha ezibangelwa "ukushisa, i-ozone, kanye ne-oxidation" ngesikhathi sokusetshenziswa (njengokuqina, ukuqhekeka, kanye nokuncipha kokunwebeka).

Ukukhiqizwa kwamathayi: Kusetshenziswa ezinhlanganisela zerabha ze-tread kanye ne-sidewall zezinhlobo ezahlukene zamathayi njengezimoto, amaloli, kanye nemishini yokwakha ukuze imelane nokushisa okubangelwa ukungqubuzana ngesikhathi sokusebenza kwezimoto kanye nokuguguleka kwe-ozone emkhathini, kubambezele ukuguga nokuqhekeka kwamathayi, futhi kwandise isikhathi sawo sokusebenza.

Imikhiqizo yerabha yezimboni: Ifanelekela amapayipi erabha (njengemipayipi kawoyela negesi), amabhande okuhambisa (okumba kanye nokuhambisa), kanye nezivalo (ama-O-rings, ama-gasket), ukuvimbela le mikhiqizo ekugugeni ngaphambi kwesikhathi kanye nokwehluleka uma ivezwa ezindaweni zangaphandle noma ezinzima (njengamazinga okushisa aphezulu kanye nomswakama) isikhathi eside.

Imikhiqizo yerabha esetshenziswa nsuku zonke/ekhethekile: esetshenziselwa imichilo yerabha ye-wiper, ama-gasket erabha, irabha emunca ukushaqeka (yezimoto/imishini), kanye nemikhiqizo eyenziwe ngerabha yokwenziwa njengerabha ye-chloroprene kanye nerabha ye-styrene-butadiene, egcina ukuthamba kwayo kwesikhathi eside kanye nokusebenza kwayo ekusetshenzisweni.

2. Izithasiselo zokuvikela irabha zezimo ezithile

Ngaphezu kokuvikelwa okuvamile, izinkinga ezithile zokuguga nazo zingaxazululwa ngokuqondile ngokusekelwe endaweni yokusetshenziswa kwemikhiqizo yerabha:

Ukuguga kokukhathala okulwa nokuguquguquka: Kusetshenziselwa izingxenye zerabha ezidinga ukucindezelwa amandla aphindaphindwayo (njengamabhande okuhambisa kanye nama-shock absorber), kunciphisa "ukuqhekeka kokukhathala" okubangelwa umphumela ohlangene wokucindezeleka okuguquguqukayo kanye ne-oxidation.

Usizo lokuvikela izinga lokushisa eliphezulu: Emikhiqizweni yerabha esetshenziswa ezindaweni ezishisa kakhulu nezishisayo (njengezivalo zenjini), uma ihlanganiswa namanye ama-antioxidants, ithuthukisa ukumelana nokushiswa kwerabha futhi iyivimbele ekuqineni ngokushesha futhi ibe buthakathaka emazingeni okushisa aphezulu.

Isici

1. Ubumsulwa ≥ 99.99%, budlula izinga lomkhakha webhethri;
2. Okuqukethwe komswakama ≤50 ppm, ukusebenza kahle kokushisa;
3.Ukuqina kokushisa okuhle kakhulu
4. Ikhona esitokweni
