Dahaarka
huruud ka-hortagga balaastikada injineernimadaMarka lagu daro photooxidation, filimka samaynta resin ee dahaarka ayaa hoos u dhigi kara hydrolysis, gaar ahaan marka heerkulka dahaarka uu kordho iftiinka qorraxda sare.Xaaladahan, molecules-ka biyaha nuugaya ee dahaarka ku jira waxay weerari karaan curaarta covalent ee resin-ka waxayna gooyaan silsiladaha polymerka, taasoo keenta miisaan unugyo hoose ah.Polyester iyo resins alkyd ayaa aad ugu nugul saameyntan marka loo eego polyurethane iyo epoxies.

Qabta Raadical Free Kaarboon
Kaarboonka xagjirka ah ee xagjirka ah ee xorta ahPolymer-ka ayaa sida caadiga ah ku jira xaalad anoxic ah oo hoos yimaada xaaladaha habaynta extrusion, nidaamkuna wuxuu ka kooban yahay tiro badan oo kaarboon ah halkii uu ka ahaan lahaa xagjirka alkoxy iyo hydroxyl radicals.Sidaa darteed, xasiliyaha farsamaynta ku habboon waa inuu awood u yeesho inuu si wax ku ool ah u qabto xag-jirayaasha kaarboonka.Antioxidant-ka hydroxylamine ee kor ku xusan waa nooc ka mid ah wakiilka dabin kaarboonka.

Caagaga gabow ° casaan
huruud ka-hortagga balaastikada injineernimadaOxidation iyo falcelinta gabowga waxay u nugul yihiin inay ku dhacaan habka loo isticmaalo balaastigga, caag iyo walxaha kale ee polymer, taasoo keentay hoos u dhigista muuqaalka muuqaalka xoogga, xoogga ka-hortagga, xoogga xajinta iyo dhererka iyo sifooyinka kale.

Waxyaalaha lagu daro
falcelinta UV, falcelinta LS, labajibbaaran falcelinta falcelintaXasijiye iftiin falcelin leh Xabagta Shiinaha (si ballaaran loo qeexay, iskudhis kasta oo polymer ah oo loo isticmaali karo sida alaabta ceeriin ee ka baaraandegidda alaabooyinka balaastiigga ah waxaa loo yaqaannaa resin) warshadaha si degdeg ah ayay u korayaan.Wax-soo-saarka badeecadu wuu sii fidayaa, siyaasadda warshadaha ee qarankuna waxay dhiirigelinaysaa warshadaha resin-ka si ay u horumariyaan jihada alaabta tignoolajiyada sare.Kala duwanaanshaha resin-ka Shiinaha waxay ahaayeen kuwo qumman, laakiin marka la barbar dhigo dhiggooda sare ee ajnabiga ah, weli waxaa jira farqi gaar ah ... -
ZJ5575
Horudhac Nambarka CAS:2122-49-8 Magaca Kiimikada: Tri-(4-hydroxy-TEMPO) Qaab dhismeedka fosfit:ZJ5575 waa nooc cusub oo ka hortag waxtar sare leh.Faa'iidooyinka Waxqabadka Iska caabbinta copolymerization ee ZJ5575 ayaa ka fiican tan phenolic, amines caraf udgoon, ethers, quinones iyo xeryahooda nitro.Codsiyada la soo jeediyay ZJ5575 waxay ku habboon tahay ka hortagga is-polymerization of olefin iyo monomer unsaturated ee habka wax soo saarka, kala-soocidda, sifaynta, kaydinta iyo gaadiidka
