Iingubo zePlastiki zePowder

Yintoni iplastiki yomgubo wokwaleka?

Iingubo zeplastiki ezigqunywe ngomgubo luhlobo lwengubo ye -thermoplastic equka ukufaka umgubo weplastiki owomileyo kwi-substrate, emva koko inyangwa phantsi kobushushu ukuze yenze ukugqitywa okuqinileyo, okuhlala ixesha elide, nokunomtsalane. Le nkqubo idla ngokusetyenziselwa ukugquma imiphezulu yesinyithi ukubonelela ngokhuseleko ekungcoleni, ekukrazukeni nasekugugulekeni, kunye nokuphucula inkangeleko yazo entle.

Inkqubo yokugquma umgubo ibandakanya amanyathelo aliqela, eqala ngokulungiselela i-substrate. Oku kubandakanya ukucoca nokulungisa umphezulu ukuqinisekisa ukuba awunangcola, ioyile, kunye nezinye izinto ezingcolisayo ezinokuphazamisa ukunamathela komgubo. Okulandelayo, umgubo ufakwa kumphezulu kusetyenziswa ibhedi emanzi okanye isibhamu se-electrostatic esibangela ukuba zinamathele kwi-substrate. I-substrate egqunyiweyo emva koko ifudunyezwa kwi-oven, enyibilikisa umgubo kwaye ibangele ukuba ugeleze kwaye uphole, yenze i-coating egudileyo, elinganayo.

eziluncedo

Enye yeenzuzo eziphambili zeplastiki yomgubo weplastiki kukuba ihambelana nokusingqongileyo. Ngokungafaniyo neengubo zolwelo eziqhelekileyo, eziqulethe izinyibilikisi ezinokukhupha ii-VOCs ezinobungozi (i-volatile organic compounds) kwi-atmosfera, iingubo zomgubo zidla ngokunganyibiliki kwaye zivelise inkunkuma encinci kakhulu. Oku kubenza babe lukhetho oluzinzileyo kunye ne-eco-friendly yokugquma uluhlu olubanzi lwemathiriyeli.

Olunye uncedo lweengubo zeplastiki zomgubo kukuba inika ukhuseleko oluhle kakhulu lwe-corrosion. I-powder coating idala umqobo phakathi kwe-substrate kunye nokusingqongileyo, ukukhusela umswakama kunye nezinye izinto ezinobungozi ekungeneni kumphezulu kwaye zibangele umonakalo. Oku kwenza ukuba iingubo zomgubo zilungele ukusetyenziswa kwiindawo ezinoburharha okanye ezinobungozi, ezinje ngolwandle okanye kwimizi-mveliso.

Iindidi zeplastiki zokugquma umgubo

Enye yezinto eziphambili ezimisela umgangatho kunye nokusebenza kweengubo zeplastiki ezigqunywe ngomgubo kukwakheka komgubo ngokwawo. Uninzi lweengubo zepowder zenziwe ngeepolymers zethermoplastic , ezenza ukugqitywa okuqinileyo nokuhlala ixesha elide ngexesha lenkqubo yokucola. Iipolymers eziqhelekileyo ezisetyenziswa kwiingubo zethermoplastic powder ziquka iPolyethylene, ipolypropylene , ipolyester, ipolyvinyl chloride, i-chlorinated polyether, ipolyamide, icellulose, ipolyester, njl.

1. Ingubo yomgubo wePolyethylene inomsebenzi ogqwesileyo wokulwa nokugqwala, ukumelana neekhemikhali, ubushushu obuhle bombane kunye nokumelana nemisebe ye-UV. Ingasetyenziselwa iitanki zeekhemikhali, ii-impellers, iimpompo, iindonga zangaphakathi zepayipi, amaqokobhe omphezulu, amaphepha esinyithi, iinethi zangaphakathi zefriji, iindawo zeemoto, njl. Isiphene sayo kukuqina okuncinci koomatshini kunye nokunamathela kakubi kwi-substrate.

2. Ingubo yomgubo wenylon , eyaziwa ngokuba yipolyamide, ineqondo eliphezulu lokunyibilika ngenxa yokubopha kwehydrogen phakathi kweeathom zechlorine kwikhonkco lemolekyuli kunye neeathom zehydrogen kwiindawo zekhonkco ezikufutshane. I-nylon inamandla aphezulu oomatshini, ukumelana nempembelelo, ubulukhuni, ukumelana nokuguguleka, i-coefficient ephantsi yokungqubana, ukufunxwa kothuli oluphantsi, njl. Ingasetyenziselwa iindawo ezikhethekileyo ezifana nee-impellers zamanzi, iindawo zoomatshini belaphu, iindawo zepiston zokuqala zenjini yedizili, iipropellers zenqanawa yokuhambisa iinqanawa, amavili eemoto, izibiyeli zeemoto, oomatshini bezolimo, izixhobo zokwakha nezemidlalo. Ingubo yomgubo wenylon ayinatyhefu, ayinancasa, imelana namanzi anetyuwa, isikhunta kunye neebhaktheriya, kwaye ifanelekile ukutshiza iindawo zoshishino lokutya, imibhobho yamanzi okusela kunye nokupakishwa kokutya.

3. Ipolyvinyl chloride powder yenye yeepolymers ezisetyenziswa kakhulu ezinokuthi zenziwe ngobuninzi emva koshishino. Inokumelana nokunyibilika okugqwesileyo, ukumelana nokugqwesa kakuhle kwamanzi kunye ne-asidi, ukumelana nempembelelo, ukuxhathisa kwetyuwa yokutshiza, kunokuthintela ukungcoliseka kokutya, kwaye ine-insulation ephezulu yokutshiza nge-electrostatic. Isetyenziselwa ikakhulu ukugquma iipaneli zentsimbi, ifenitshala yentsimbi, izixhobo zeekhemikhali, njl.

4. I-Fluororesin powder yokugquma inokulungiswa kwiipolymers ezahlukeneyo ze-fluorinated, ezifana ne-polytetrafluoroethylene (PTFE), i-polytrifluorochlorethylene (PTFCE), i-polyvinylidene fluoride (PVDF), njl. PTFE inendawo yokunyibilika ephezulu ukuya kuthi ga kwi-327℃ kwaye ingasetyenziselwa ixesha elide kuluhlu lwe -250 ~ 250℃. Ikwanayo nokumelana nokugqwesa okugqwesileyo, nakwi-aqua regia, umsebenzi ogqwesileyo we-dielectric, i-coefficient ephantsi kakhulu ye-friction kunye neempawu zokuzithambisa, ngenxa yoko yaziwa ngokuba "yinkosi yeplastiki". Isetyenziswa kakhulu kwi-petroleum, iikhemikhali ezichasene ne-corrosion coatings, ukutywinwa, ukuthwala izinto zokuthambisa, izinto zombane kunye nezombane, iileyili zokusungula iinqanawa kunye neengubo zepani ezingabambekiyo. I-PTFCE inexabiso eliphantsi kune PTFE, kwaye ubushushu bokusebenza bunokuthotywa. Ukwaleka kungasetyenziswa ixesha elide ngaphantsi kwe-130 ℃. Ukukwazi kwayo ukumelana ne-alkali kunye ne-fluor

Ngokubanzi, iingubo zeplastiki zomgubo lukhetho oluguquguqukayo nolusebenzayo olunika uluhlu lweenzuzo kunye neenzuzo ngaphezu kweengubo zolwelo eziqhelekileyo. Ukusuka kwiipropathi zayo ezihambelana nokusingqongileyo ukuya ekudlekeni kwayo okugqwesileyo kunye nokumelana nemozulu, ukugquma komgubo lukhetho oluya luthandwa kakhulu kwimizi-mveliso eyahlukeneyo kunye nokusetyenziswa.
