UKUPAKISHA NOKUGCINA

• Imveliso mayipakishwe kwisikhongozeli esicocekileyo, esomileyo, esikhuselekileyo nesivalekileyo, ubunzima obupheleleyo obuyi-220 Kg.
• Ixesha lokugcinwa: Iinyanga ezi-6 ngaphantsi kwama-25℃, zigcinwe kwindawo epholileyo necocekileyo
indawo enomoya.
• Nasiphi na imfuneko ekhethekileyo yokupakisha, nceda unxibelelane neqela lethu lenkxaso

PHAWULA

• Lonke ulwazi olukule khathalogu lusekelwe kwiimvavanyo eziqhelekileyo ze-GB/T8237-2005, kuphela ngenjongo yokubhekisela; mhlawumbi zahluke kwidatha yovavanyo lokwenyani.
• Kwinkqubo yokuvelisa iimveliso ze-resin, kuba ukusebenza kweemveliso zomsebenzisi kuchatshazelwa zizinto ezininzi, kuyimfuneko ukuba abasebenzisi bazivavanye ngaphambi kokuba bakhethe kwaye basebenzise iimveliso ze-resin.
• Iiresini zepolyester ezingagcwaliyo azizinzanga kwaye kufuneka zigcinwe ngaphantsi kwama-25°C emthunzini opholileyo, zihanjiswe kwikhareji okanye ebusuku, ziphephe ukukhanya kwelanga.
•Nayiphi na imeko engafanelekanga yokugcina nokuhambisa impahla iya kubangela ukuba ixesha layo lokuphelelwa lixabiso lifutshane.

IMIYALELO

• I-resin ye-7937 ayinazo izongezo ze-wax, i-accelerator kunye ne-thixotropic.
• I-resin ye-7937 ifanelekile ukunyibilika kubushushu begumbi kunye nobushushu obuphakathi. Ukunyibilika kubushushu obuphakathi kulungele ngakumbi ulawulo lwemveliso kunye nokuqinisekiswa kokusebenza kwemveliso. Icetyiswa kwinkqubo yokunyibilika kubushushu obuphakathi: i-tert-butyl peroxide isooctanoate TBPO (umxholo ≥97%), umxholo we-resin we-1%; ubushushu bokunyibilika, 80±5℃, ukunyibilika ubuncinane iiyure eziyi-2.5. Iarhente yokudityaniswa ecetyiswayo: i-γ-methacryloxypropyl trimethoxysilane KH-570, umxholo we-resin we-2%.
• I-resin ye-7937 inokusetyenziswa ngokubanzi; kucetyiswa ukuba ukhethe i-resin ye-7982 okanye i-o-phenylene-neopentyl glycol 7964L eneemfuno zokusebenza eziphezulu; kucetyiswa ukuba ukhethe i-m-phenylene-neopentyl glycol 7510 yokumelana kwamanzi aphezulu, ukumelana nobushushu kunye nokumelana nemozulu. I-resin; ukuba izixhobo zinokuhlangabezana neemfuno, nceda ukhethe i-resin ye-isophthalic 7520 engaphantsi kwe-viscosity, engabizi kakhulu kwaye esebenza ngcono.
• Kwinkqubo yokuvelisa imveliso, emva kokufudumeza nokucocwa, kufuneka ithotywe kancinci ukuya kubushushu begumbi, ukuze kuthintelwe ukupholisa ngokukhawuleza, ukuthintela ukuguquka okanye ukuqhekeka kwemveliso, ingakumbi ebusika. Ukusikwa nokupholishwa kwelitye le-quartz kwinkqubo yokuvelisa kufuneka kwenziwe emva kokuba icociwe ngokwaneleyo.
• Ukufunxwa komswakama kwesixhobo sokuzalisa kufanele kuthintelwe. Ubuninzi bomswakama obuninzi buya kuchaphazela ukuqiniswa kwemveliso kwaye bubangele ukuwohloka kokusebenza.
