Xidhmada Alaabta

Codsiga Alaabta

MTHPA waxaa inta badan loo isticmaalaa sidii daaweeyaha resins epoxy. Waxay leedahay u janjeera hoose inay ka nuugaan qoyaanka hawada iyo eber ama samaynta ugu yar ee kaarboon laba ogsaydh marka lagu daro dardargeliyayaasha amine sare.

MTHPA si fudud ayaa loogu walaaqi karaa resins dareere ah oo kala duwan oo siinaya xasiloon, isku dhafka viscous hooseeya iyo nolosha dheriga dheer.

Waxaa si weyn loo isticmaalaa:

-Dhalidda/Dhariga

- Uurka

- Lamination

Dhinaca balaastigga la xoojiyay waxaa loo isticmaalaa alaabada nabarrada fiilooyinka (tuubooyinka saliidda, tiirarka iyo alaabta ciyaaraha), go'yaal la dhejiyay, looxyada wareegga daabacan, qalabka beddelka.

Thanks to astaamaheeda dahaarka ee aadka u wanaagsan, MTHPA waxay heshay codsiyo badan oo loogu talagalay soo saarista qaybaha korantada sida: capacitors, resistors, transformers qaybo fiilooyinka, gariiradda dabka, duulista dib u duulista.

Methyltetrahydrophthalic anhydride (MTHPA) waa unug kiimiko ah oo hoos yimaada qaybta anhydrides meertada ah. Waxa ugu horayn loo istcimaalaa sidii wakiilka daawaynta ee resins epoxy. Waa kuwan qaar ka mid ah faa'iidooyinka ugu muhiimsan ee MTHPA:
Guryaha 1.Curing: MTHPA waa wakiilka daaweynta waxtarka leh ee resins epoxy, siinta kulayl aad u fiican iyo iska caabbinta kiimikada. Waxay ka caawisaa in ay u beddelo xabagta epoxy-ga dareeraha ah shay adag, waarta, iyo heerkulbeeye, taas oo ka dhigaysa mid ku habboon codsiyo kala duwan.
2.Low viscosity: MTHPA sida caadiga ah waxay leedahay viscosity hoose marka la barbar dhigo wakiilada kale ee daaweynta, taas oo ka dhigaysa in ay fududahay in la xakameeyo iyo qas epoxy, hagaajinta habraaca iyo sifooyinka codsiga.
3.Xasilloonida kulaylka wanaagsan: epoxy la daaweeyay oo leh MTHPA waxay soo bandhigaysaa xasilloonida kulaylka wanaagsan, taas oo ka dhigaysa mid ku habboon codsiyada meesha iska caabbinta heerkulka lagama maarmaanka u ah.
4..Good koronto guryaha: Epoxy resins la MTHPA sida wakiilka daawaynta inta badan uu leeyahay koronto la jecel yahay.

Baakad

Baakadaha: durbaan galvanized 220 kg bulk marka la codsado nooc kale oo baakad ah ayaa la heli karaa.

Kaydinta: waa in lagu kaydiyaa meel ka durugsan holac furan ama ilo kale oo shidi kara, waana in laga ilaaliyaa qoyaanka sababtoo ah, gaar ahaan PI iyo 600 nooc, si fudud ayaa crystallizes marka ay la xiriirto qoyaanka hawada. Xilliga jiilaalka MTHPA way adkaan kartaa, si fudud ayaa loogu dhalaali karaa si fudud.

Nolosha shelf:12 bilood laga bilaabo taariikhda wax soo saarka.

Kaydinta alaabta iyo gaadiidka

Haddii aan si kale loo cayimin, alaabta MTHPA waa in lagu kaydiyaa meel qalalan, qabow oo aan qoyaanka lahayn. Sida ugu fiican loo isticmaalo 12 bilood gudahood ka dib taariikhda wax soo saarka. Waa inay ku jiraan baakaddoodii asalka ahayd ilaa inta aan la isticmaalin. Alaabtu waxay ku habboon tahay in lagu geeyo habka markabka, tareenka, ama xamuulka.
