Polyester Resin Powder Coating
Intshayelelo ngokubanzi:
Yenziwe nge-carboxyl polyester resin, i-pigment filler kunye ne-TGL njengearhente yokunyanga, enokumelana nemozulu ephezulu kunye nokuxhathisa kwe-UV. Iipropathi ezilungileyo zoomatshini, ubunzima obuphezulu, ukuchasana nokukrweleka, ukuxhathisa ukubola; Ipropathi yomgangatho omhle, ifilimu ngokusisiseko ayinama-pinholes, imingxuma yokunciphisa kunye nezinye iziphene; Ingasetyenziselwa iimveliso zentsimbi zangaphandle ezifana ne-air conditioner, izibane zangaphandle kunye nezibane.
Uluhlu lweMveliso:
Ukubonelela ngamagqabantshintshi (80% ngasentla), isemi-light (50-80%), iglasi engenanto (20-50%) kwaye akukho ukukhanya (20% ngezantsi) iimveliso okanye kwiimfuno
Iinkcazelo Ngeempawu:
Umxhuzulane okhethekileyo(g/cm3, 25℃) : 1.2-1.7
Ukuhanjiswa kobungakanani besuntswana: 100% ngaphantsi kwe-100 micron (Inokulungelelaniswa ngokweemfuno ezikhethekileyo zokupeyinta)
Iimeko zokwakha:
Ukulungiswa kwangaphambili: umphezulu kufuneka ucocwe ngokucokisekileyo ukususa ioli kunye nokugqwala. Ukusetyenziswa kwe-iron series phosphating okanye umgangatho ophezulu we-zinc series phosphating inokuphucula ngakumbi isakhono sokukhusela umhlwa.
Imo yokunyanga: ukwakhiwa kompu omileyo owenziwe ngesandla okanye ozenzekelayo
Iimeko zokunyanga: 190-200 ℃ (ubushushu bokusebenza), imizuzu eyi-10

Amanqaku:
1.Olu vavanyo lungentla lusebenzise iipleyiti zentsimbi eziqengqelekayo eziyi-0.8mm ezinobukhulu obungama-30-40 eemicrons emva konyango lwangaphambili.
2.Isalathiso sokusebenza sale ngubo ingentla inokuncipha kancinci ngokuncipha kweglosi.
Umndilili wokugubungela:
8-11 sq.m./kg; Ubukhulu befilimu bungama-70 eemicrons (zibalwe nge-100% yokusetyenziswa komgubo wokugquma)
Ukupakisha kunye nokuthutha:
iikhathoni zifakwe iingxowa ze-polyethylene, ubunzima bobunzima bungama-20kg; Izinto ezingekho yingozi zinokuthuthwa ngeendlela ezahlukeneyo, kodwa kuphela ukuphepha ukukhanya kwelanga, umswakama kunye nobushushu, kwaye ugweme ukudibanisa nezinto zekhemikhali.
IiMfuno zoGcino:
Icocekile, yomile, ingena umoya, kude nokukhanya, ubushushu begumbi bungaphantsi kwe-30 ℃, kwaye kufuneka igqunywe kumthombo womlilo, kude nomthombo wobushushu.Ixesha logcino olusebenzayo ziinyanga ezi-6 ukusuka kumhla wokuvelisa. Emva kwexesha lokugcina, lingaphinda lihlolwe kwaye lisetyenziswe kwakhona ukuba iziphumo zihlangabezana neemfuno. Zonke izikhongozeli kufuneka zipakishwe ngokutsha kwaye zibuyiselwe kwipakethe yazo yokuqala emva kokusetyenziswa.
Amanqaku:
Zonke ii powders ziyayicaphukisa inkqubo yokuphefumla, ngoko ke kunqanda ukuphefumla umgubo kunye nomphunga ekunyangeni. Zama ukuphepha ukudibanisa ngokuthe ngqo phakathi kwesikhumba kunye nomgubo wokugquma. Hlamba ulusu ngamanzi kunye nesepha xa kufuneka ukudibana. Ukuba ukudibana kwamehlo kwenzeka, hlamba ulusu ngokukhawuleza ngamanzi acocekileyo kwaye ufune unyango ngokukhawuleza. Umaleko wothuli kunye ne-powder particle deposition kufuneka igwenywe kumphezulu kunye nekona efileyo. Amasuntswana amancinci aphilayo aya kuvutha kwaye abangele ukuqhuma phantsi kombane omileyo. Zonke izixhobo kufuneka zibekwe phantsi, kwaye abasebenzi bokwakha kufuneka banxibe izihlangu ezichasene ne-static ukugcina umhlaba ukuthintela umbane ongatshintshiyo.
