Ukhetho lweikhoyili yentsimbi epeyintwe ngaphambili(i-ppgi ppgl) ibhekiselele ekukhethweni kweempawu zoomatshini, uhlobo lwe-substrate (uhlobo lwe-coating) kunye nobukhulu bokugquma, ukusebenza kwengubo yangaphambili kunye nokusebenza kwe-back back.Ukusetyenziswa, ukubola kokusingqongileyo, ubomi benkonzo, ukuqina, indlela yokucubungula kunye nenqanaba lokuguqulwa zizinto ezibalulekileyo ekufuneka ziqwalaselwe xa ukhetha.ppgi ikhoyilikwayeppgl ikhoyili.
Ukukhethwa kweempawu zomatshini, uhlobo lwe-substrate kunye nobunzima bokugquma
Iimpawu zomatshini zikhethwa ngokukodwa ngokwezinto ezifana nesicelo, indlela yokucubungula kunye neqondo lokuguqulwa.Umzekelo, iiphepha lophahlayesakhiwo ngokuqhelekileyo ayithwali mthwalo, kwaye i-deformation ayinzima ngexesha lokucubungula, ngokoDX51Diqhele ukukhethwa.Kwiindawo ezineqondo elikhulu lokuguqulwa, izixhobo ezinokwakheka okulungileyo njenge-DX52D kunye ne-DX53D kufuneka zikhethwe.Kumacandelo aneemfuno ezinzima, insimbi efanelekileyo yesakhiwo kufuneka ikhethwe ngokweemfuno zokuyila.Iindlela ezisetyenziswa ngokuqhelekileyo zamaphepha afakwe umbala ziquka ukucheba, ukugoba, ukuqengqeleka, njl.
Ukongeza, ekubeni iipropathi zoomatshini ze-substrate zihlala zisetyenziselwa ukubuyisela iipropati ze-mechanical of theipleyiti enombalakwimveliso yangempela, kunye nenkqubo yokugqoka umbala ingakhokelela ekutshintsheni kwiipropati zemishini ye-substrate, ingqalelo kufuneka ihlawulwe kule nto.Uhlobo lwe-Substrate (uhlobo lokutyabeka) kunye nobukhulu bokugquma zikhethwa ikakhulu ngokusekelwe kwizinto ezifana nesicelo, ukubola kokusingqongileyo, ubomi benkonzo kunye nokuqina.I-Anti-corrosion yenye yemisebenzi ephambili yecoil yentsimbi efakwe umbala (ppgi ppgl ikhoyili).Uhlobo lwengubo kunye nobukhulu becala yizona zinto ziphambili ezichaphazela ukuxhatshazwa kwe-corrosion yephepha elifakwe umbala.Kuba iikhoyili ezigqunywe ngombala zokwenza ulwakhiwo zidla ngokutyhileka ngokuthe ngqo kwimo engqongileyo ye-atmospheric, substrates ezifanaashushu-dip galvalume sheetskwayeashushu-diphu amashitingokuxhathisa kakuhle umhlwa kunye neengubo ezishinyeneyo zidla ngokukhethwa.
Ukukhetha ukusebenza kokutyabeka ngaphambili kubhekiselele kukhetho lohlobo lokutyabeka, ukutyeba kokutyabeka, umahluko wombala wokugquma, iglosi yeglosi, ubulukhuni bokugquma, ukuguquguquka / ukuncamathela, ukomelela kokutyabeka kunye nezinye iipropathi.
Uhlobo lokwaleka
Ipeyinti ephezulu yokugqoka:Iingubo eziphezulu ezisetyenziswa ngokuqhelekileyo ziyi-polyester, i-silicon-modified polyester, i-polyester ehlala ixesha elide kunye ne-polyvinylidene fluoride, kwaye kukho ukungafani okuthile kobunzima, ukuguquguquka / ukunamathela, kunye nokuxhathisa ukubola kwee-topcoat ezahlukeneyo.
