Izindlela zokuphepha zokuhamba: Lo mkhiqizo uwuketshezi, unqatshelwe ngokuphelele ukuxubana ne-oxidant, amakhemikhali adliwayo, i-alkali, i-acid anhydride, njll. Ngesikhathi sokuthutha, kufanele uvikelwe ekukhanyeni kwelanga, imvula kanye nezinga lokushisa eliphezulu.Ehlobo ngangokunokwenzeka ekuseni nakusihlwa zokuhamba, ukuvimbela ukukhanya kwelanga, ukuthutha ngokusho komugqa oshiwo, ukuma kufanele kube kude nomlilo, imithombo yokushisa, indawo yokushisa ephezulu.Akuvunyelwe ngokuphelele ukuthutha izimpahla ngemoto efanayo namakhemikhali adliwayo.Lapho uthuthwa ngomgwaqo, kufanele ulandele umzila onqunyiwe futhi ungahlali ezindaweni zokuhlala nezinabantu abaningi.Akuvunyelwe ukuwashelela kwezokuthutha ngololiwe.Imikhumbi yokhuni nemikhumbi kasimende inqatshelwe ngokuphelele ukuthutha ngobuningi.
I-P-tert-butylphenol ine-antioxidant futhi ingasetshenziswa njengesiqinisi serabha, insipho, ama-hydrocarbon ane-chlorinated kanye nemicu yokugaya ukudla.Ukumunca i-Uv, isibulala-zinambuzane, irabha, upende nokunye okunqanda ukuqhekeka.Isibonelo, isetshenziselwa i-polycarbon resin, i-tert-butyl phenolic resin, i-epoxy resin, i-polyvinyl chloride, i-styrene stabilizer.Ngaphezu kwalokho, kuphinde kube yimpahla eluhlaza yesibulala-zinambuzane ezenza imithi, isibulala-zinambuzane kanye ne-acaricide, iphunga elimnandi ne-ejenti yokuvikela izitshalo.Ingasetshenziswa futhi njengesithambisi, isincibilikisi, isithasiselo sikadayi nopende, i-antioxidant yamafutha okugcoba, i-demulsifier kawoyela kanye nesengezo samafutha emoto.
Ezinye izinhlelo zokusebenza:
(1) Nge-phenolic resin encibilikayo kawoyela, umkhiqizo kanye ne-formaldehyde condensation ingatholwa ngezinhloso ezahlukahlukene.Ku-adhesive ye-chloroprene exutshwe u-10-15% womkhiqizo, ukuze uthole inhlaka encibilikayo, lolu hlobo lokunamathisela lusetshenziswa kakhulu kwezokuthutha, ukwakhiwa, ukwakhiwa kwezicathulo, njll. ukuphrinta, i-photogravure ethuthukisiwe nokunye.Ku-varnish ye-insulation, ingasetshenziswa ku-coil dip varnish kanye ne-laminate varnish.
(2) Ngokukhiqizwa kwe-polycarbonate, njenge-ejenti yokunqanyulwa kwe-phosgene polycarbonate, wengeza inani le-Chemicalbook lika-1-3% we-resin.
(3) Isetshenziselwa i-epoxy resin, ukuguqulwa kwe-xylene resin;Njenge-polyvinyl chloride stabilizer, i-surfactant, i-UV absorber.
(4) Ngezindawo zokulwa ne-antioxidant, ingasetshenziswa njengenjoloba, insipho, ama-hydrocarbon ane-chlorinated kanye ne-nitrocelluloose stabilizer.Iphinde ibe yimpahla eluhlaza yesixosha izinambuzane (umuthi), i-acaricide acaride (isibulala-zinambuzane) kanye ne-ejenti yokuvikela izitshalo, iphunga elimnandi, i-synthetic resin, futhi ingasetshenziswa njengesithambisi, isinyibilikisi, udayi nesithasiselo sikapende.Ingasetshenziswa futhi njengesithako se-demulsifier endaweni kawoyela kanye nesengezo samafutha emoto.
