Walxaha Kiimikada-Methylene Chloride Oo Lagu Sameeyay Shiinaha

Hordhac Product

Kiimikada Richar waa bixiye xirfadle ah oo Shiinaha ah oo soo saara darajada warshadaha dichloromethane ee laga sameeyay Shiinaha, kaas oo ku hawlanaa kiimikooyinka dabiiciga ah muddo 10 sano ah. Bixinta muunada bilaashka ah, waxaanu si diiran kuugu soo dhawaynaynaa inaad iibsato kiimikooyin tayo sare leh oo CAS ah oo leh nadiif sare iyo qiimo jaban annaga.

Faahfaahinta alaabta
Qaaciddada molecular: CH2CL2
Miisaanka molecular: 84.93
Qalabka jirka iyo kiimikaad: dareere kacsan oo aan midab lahayn, oo la mid ah urta ether iyo macaan.
Cufnaanta qaraabada: D4201.326Kg/L.
barta karkarinta: 40.4 DEG C.
dhibic dhalaalaysa: -96.7 darajo, barta shidda ee 615 DEG C. Waxoogaa ku milmay biyaha, milanka ethanol, ether ether, sun ah, kicinta maandooriyaha. Dichloromethane iyo falcelinta hydrolysis biyaha, dichloromethane oo ka kooban xasiliye ganacsi, si looga hortago hydrolysis. Dichloromethane iyo ogsijiinta xoogga badan ayaa soo saari doona isku dhafka qarxa, laakiin aan guban karin, ayaa inta badan loo adeegsadaa warshadaha sunta yar, dareere aan guban karin iyo barta karkarinta hoose.

Ujeedo
Wixii dareere ah oo aan guban karin: nadiifinta birta, rinjiga saarista, wakiilka birta birta, saddex dareere acetate cellulose; filim, aerosol, antibiyootiga iyo fiitamiinnada soo saarista dareeraha; wakiilka xumbo ee loogu talagalay soo saarista balaastikada injineernimada; alaabada ololka celisa; loo isticmaalo in lagu beddelo F11 iyo F12 isticmaalka alaabta; alaabada kiimikaad ee wanaagsan.

Baakadaha, kaydinta iyo gaadiidka
Birta galvanized, durbaanka birta madow ama haanta baakadaha daboolan ee buuxinta mugga dichloromethane, 80%, waxay siin kartaa ilaalinta nitrogen ee isticmaaleyaasha leh shuruudo gaar ah. Kaydinta waa in lagu kaydiyaa meel qabow oo qallalan, bakhaarku waa in hawo la saaro si looga fogaado in ay la kulmaan xaddi badan oo ogsajiin ah ama oksijiin, si looga fogaado in biyaha la taabto si looga hortago biyo la'aanta. Gaadiidku waa in uu u hoggaansamaa xeerarka Jamhuuriyadda Dadka ee Shiinaha ee khuseeya qaadista kiimikooyinka khatarta ah ee waddooyinka waaweyn iyo tareenada.

Caafimaadka iyo badbaadada

Sichloromethane ee xadka qaraxa hawada: 8.1 ~ 17.2%, waxaa iska leh kiimikooyinka guban kara. Feejignaanta sare, soo-gaadhista waqti dheer waxay si fudud u keentaa dawakhaad, hurdo, lallabbo, tinnitus ama kabuubyada addimada, u guurto hawo cusub, calaamadaha si dhakhso ah loo soo celiyo, ma keeni doonaan dhaawac waara. Kala-soocidda indhaha waxay keentaa xanuun iyo xanaaq, taabashada muddada dheer ee maqaarka waxay sababi kartaa dermatitis.
