Ipeyinti yePolyurethane eqhutywa ngamanzi
I-trapezium ekhethekileyo esekwe emanzini engeniswe kwamanye amazwe, isayensi yekhemikhali yesizwe, amanzi angenawo i-ion, izongezo ezisekwe emanzini kunye nesithambisi sokukhusela okusingqongileyo kunye nezinye izinto, ayinayo i-benzene, i-benzene yosapho, i-benzene yodidi lwesibini kunye nezinye izinyibilikisi zendalo. Imveliso ilungiswa ngokusebenzisa i-resin ye-polyurethane esekwe emanzini njengezinto ezisisiseko zokwenza ifilimu, i-HDI njengearhente yokuphilisa, yongeza izithambisi ezinobuhlobo nokusingqongileyo kunye nezincedisi ezisebenzayo. Ifilimu epheleleyo, i-gloss ephezulu, umbala oqaqambileyo. Ukunamathela okuhle, ubunzima obuphezulu, ukumelana nemozulu okuhle kakhulu.
Intsimi yesicelo
Ifanelekile kwiimfuno eziphezulu zomphezulu, iimfuno zokumelana nemozulu ephezulu zopende ophezulu. Isetyenziswa kakhulu ekuhombiseni umphezulu wezinto zesinyithi ezifana nebharele yenqaba yamandla omoya, izixhobo zoomatshini, oomatshini bokwakha, umbhobho weoyile ye-petrochemical, njl. Inokuxhathisa imozulu yangaphandle kakuhle kakhulu kunye nokumelana nokugqwala.
Unyango lomphezulu
1. Umphezulu kufuneka ucoceke kwaye wome, kwaye unyango lomphezulu we-substrate kufuneka luhlangabezane neemfuno.
2. Izixhobo ezisetyenziswa ekwakheni mazibe zomile kwaye zicocekile. 3.
3. akuvumelekanga ukudibana ne-asidi kunye ne-alkali ngexesha lokulungiselela ipeyinti kunye nokufaka ipeyinti.
4. ixesha lokupenda kufuneka lilawulwe ngokungqongqo, xa ubushushu buyi-25′C, ixesha lokupenda aliyi kuba ngaphantsi kweeyure ezili-12.
5. Ayikwazi ukupenda ubukhulu, ifilimu ayinakudlula i-40μm okanye iya kuphuma amaqamza.
6. Ukwakhiwa nokomiswa kunye nokunyanga ngexesha lokufuma okufanelekileyo akudluli kwi-75%, ubushushu abunakuba ngaphantsi kwe-0 ℃ C, kungenjalo ifilimu ayinakunyangwa ngokupheleleyo.
