Ifektri nabakhiqizi be-China Unsaturated Polyester Resin

Abakhiqizi be-Polyester Resin Engagcwali

incazelo emfushane:

I-resin ye-7937 iyi-resin ye-polyester engagcwele i-ortho-phthalic ene-anhydride ye-phthalic, i-anhydride yama-maleic kanye nama-diols ajwayelekile njengezinto zokusetshenziswa eziyinhloko.
Inikeza izakhiwo ezinhle zokumelana namanzi, uwoyela kanye nokumelana nokushisa okuphezulu.

UKUPAKISHA NOKUGCINA

• Umkhiqizo kufanele upakishwe esitsheni esihlanzekile, esomile, esiphephile nesivaliwe, isisindo esiphelele esingu-220 kg.
• Isikhathi sokuphila eshalofini: izinyanga eziyi-6 ngaphansi kwama-25℃, sigcinwe endaweni epholile futhi ehlanzekile
indawo enomoya.
• Noma yisiphi isidingo sokupakisha esikhethekile, sicela uxhumane nethimba lethu lokusekela

QAPHELA

• Lonke ulwazi olukulolu hlu lusekelwe ezivivinyweni ezijwayelekile ze-GB/T8237-2005, ukuze lubhekiselwe kuphela; mhlawumbe luhluke kudatha yangempela yokuhlolwa.
• Enqubweni yokukhiqiza yokusebenzisa imikhiqizo ye-resin, ngoba ukusebenza kwemikhiqizo yomsebenzisi kuthintwa yizici eziningi, kubalulekile ukuthi abasebenzisi bazihlole ngaphambi kokukhetha nokusebenzisa imikhiqizo ye-resin.
• Ama-resin e-polyester angagcwele awazinzile futhi kufanele agcinwe ngaphansi kwama-25°C emthunzini opholile, ahanjiswe emotweni efrijini noma ebusuku, egwema ukukhanya kwelanga.
• Noma yisiphi isimo esingafanele sokugcina nokuthutha impahla sizobangela ukufinyezwa kokuphila kwayo eshalofini.

IMYALELO

• I-resin engu-7937 ayinazo izithako ze-wax, i-accelerator kanye ne-thixotropic.
• I-resin engu-7937 ifanelekela ukupholisa ekamelweni lokushisa kanye neliphakathi. Ukupholisa izinga lokushisa eliphakathi kusiza kakhulu ekulawuleni ukukhiqizwa kanye nokuqinisekisa ukusebenza komkhiqizo. Kunconywa ohlelweni lokupholisa izinga lokushisa eliphakathi: i-tert-butyl peroxide isooctanoate TBPO (okuqukethwe ≥97%), okuqukethwe kwe-resin okungu-1%; izinga lokushisa lokupholisa, 80±5℃, ukupholisa okungenani amahora angu-2.5. I-ejenti yokuhlanganisa enconywayo: i-γ-methacryloxypropyl trimethoxysilane KH-570, okuqukethwe kwe-resin okungu-2%.
• I-resin engu-7937 inokusebenza okubanzi; kunconywa ukuthi ukhethe i-resin engu-7982 noma i-o-phenylene-neopentyl glycol 7964L enezidingo zokusebenza eziphakeme; kunconywa ukuthi ukhethe i-m-phenylene-neopentyl glycol 7510 ukuze uthole ukumelana kwamanzi okuphezulu, ukumelana nokushisa kanye nokumelana nesimo sezulu. I-resin; uma imishini ingahlangabezana nezidingo, sicela ukhethe i-resin engu-isophthalic 7520 ene-viscosity ephansi, engabizi kakhulu futhi esebenza kangcono.
• Enqubweni yokukhiqiza umkhiqizo, ngemva kokushisa nokuphola, kufanele wehliswe kancane kancane uye ekushiseni kwegumbi, ukuze kugwenywe ukupholisa okusheshayo, ukuvimbela ukuguquka noma ukuqhekeka komkhiqizo, ikakhulukazi ebusika. Ukusikwa nokupholishwa kwetshe le-quartz enqubweni yokukhiqiza kufanele kwenziwe ngemva kokupholisa okwanele.
• Ukumuncwa komswakama kwesigcwalisi kufanele kugwenywe. Ubuningi bomswakama obuningi buzothinta ukuqiniswa komkhiqizo futhi kubangele ukuwohloka kokusebenza.
