IBanga leBhotile yaManzi iPET Resin (PET)
Intshayelelo yeMveliso
Iitshiphusi zepolyester zenqanaba lebhotile zamanzi zifanelekile ukwenza iibhotile zokupakisha zamanzi acocekileyo, amanzi amaminerali endalo, amanzi adityanisiweyo, amanzi okusela, izikhongozeli zencasa kunye neelekese, ibhotile ye-makeup kunye nephepha le-PET njl njl.
Uphawu lwemveliso lubonisa umxholo wentsimbi enzima, umxholo ophantsi we-acetaldehyde, ixabiso lombala olungileyo, i-viscosity ezinzileyo.Ngenkqubo eyodwa yeresiphi kunye neteknoloji yemveliso ephucukileyo, imveliso ineempawu ezibalaseleyo zokusetyenzwa, ubushushu obuphantsi bokusetyenzwa, umda obanzi wokusetyenzwa, ukungafihli okugqwesileyo kunye nomgangatho ophezulu wemveliso.Ekwenzeni iibhotile, imveliso inokuthotywa okuncinci kunye nomxholo ophantsi we-acetaldehyde.Ngelixa iqinisekisa ukhuseleko kunye nococeko, inokugcina ngokufanelekileyo incasa eyodwa yamanzi acociweyo, amanzi anezimbiwa kunye namanzi adityanisiweyo.

Iimeko zoLungiselelo oluqhelekileyo
Ukomisa kuyimfuneko ngaphambi kokuba kuqhutywe ukunyibilika ukukhusela i-resin kwi-hydrolysis.Iimeko zokomisa eziqhelekileyo zibushushu bomoya 160-180 ° C , 4-6 iiyure zokuhlala ixesha, iqondo lokushisa ngamazolo ngaphantsi -40 * C.
Ubushushu bomphanda obuqhelekileyo malunga nama-275-293°C.
