1. Izinto kunye neempawu ezisisiseko
- I-Nylon (iPolyamide, iThermoplastic): Ikhonkco le-molecular elibotshelelwe yi-hydrogen; inqanaba lokunyibilika yi-180-190℃; uxinano lwe-1/7 yobhedu, kodwa ayigugi ngokuphindwe kasibhozo. I-coefficient ephantsi yokungqubana (ukuzithambisa), ingxolo ephantsi, ayinatyhefu, ikhuselekile ekunxibelelaneni nokutya (ihambelana ne-21 CFR 175.300).
- I-Polyester (iThermoset): Amaqela e-Polar; Iintlobo ze-TGIC/ezingezizo ze-TGIC; isakhiwo esidibeneyo esingenakuguqulwa emva kokunyangwa. Ukumelana okuhle kakhulu kwe-UV, ukukhanya okuphezulu (40-80 @60°), ukulingana okuhle (akukho xolo loorenji ukuba ubukhulu bulawulwa).
2. Uthelekiso lweNtsebenzo oluPhambili
| Umgangatho wokuSebenza |
I-Nylon Powder Coating |
IiPolyester Powder Coating |
| Ukunxiba Ukumelana |
Igqwesile (ukulahleka kweTaber 8-18mg); ilungele ukushukuma kweendawo |
Kulungile; ifanelekile kwiimeko zokunxiba ngokubanzi |
| Ubume bemozulu |
Iphakathi; ifunxa umswakama (ifuna indawo yokugcina evaliweyo) |
Igqwesile; Iqinisekiswe yi-AAMA 2603; ukugcinwa kombala ngaphandle |
| Ukuchasana neMichiza |
Ibuthathaka (ayimelani ne-asidi/i-alkali); i-epoxy-modified ukuze ikhusele ukugqwala |
Ilungile (ingcono kune-epoxy); ukumelana netyuwa kangangeeyure ezili-1000 nangaphezulu |
| Ukuhombisa |
Ukhetho oluncinci lombala; ukukhazimla okuphakathi |
Imibala etyebileyo (yesinyithi/engacwebezeliyo); inqanaba eliphezulu |
| Ukuzinza kobushushu |
I-thermoplastic (iyanyibilika kwakhona); ukumelana nobushushu okuphantsi |
I-thermoset (ayinakuguqulwa); ukumelana nobushushu okuphezulu |
| Ukungena kwamanzi |
Phezulu (kufuneka ulawulo lokufuma) |
Iphantsi; ukulungelelana okuqinileyo nokusingqongileyo |
3. Usetyenziso oluqhelekileyo
- I-Nylon: Izixhobo ezigudileyo (iibheringi/iigiya), izixhobo zokunxibelelana nokutya, izixhobo zesandla, izixhobo zasemanzini
- I-Polyester: Izinto zokwakha zangaphandle, izixhobo zasekhaya, iinxalenye zeemoto, iindawo zokuvala zoshishino
4. Inkqubo kunye neendleko
| Ingxaki |
I-Nylon Powder Coating |
IiPolyester Powder Coating |
| Indlela yo ku sebenza |
Ibhedi ene-fluidized + iprimer (yokuncamathela); 650°F unyango lwangaphambi konyango + 475°F ukunyanga |
I-electrostatic spray (ukusebenza kakuhle kokudlulisa); ubushushu obuphantsi bokunyanga |
| Iindleko zeMathiriyeli ekrwada |
Ngaphezulu ($12-15/kg kwi-PA12) |
Eyongayo ($2-3/kg; iphantsi ngobuninzi) |
| Iindleko zokwakha |
Iindleko ezifihlakeleyo (ulawulo lokufuma/iprimer) |
Ukusetyenziswa kwamandla aphantsi; Ukugubungela okungu-4㎡ kwi-500g nganye |
| Iindleko zoBomi |
Ubomi benkonzo ende kwiindawo ezinxibe kakhulu |
Ulondolozo oluphantsi lokusetyenziswa ngaphandle |
5. Isikhokelo soKhetho
- Khetha iNylon: Beka phambili ukumelana nokuguguleka, ukuthambisa, okanye ukhuseleko lokutya (izixhobo zoomatshini, izixhobo zokutya)
- Khetha iPolyester: Beka phambili ukuchaneka kwemozulu, ukuhombisa, okanye ulawulo lweendleko (iimveliso zangaphandle, ukuveliswa ngobuninzi)
- Izisombululo zeHybrid: I-nylon eguqulwe yi-Epoxy (iindawo zokuguguleka ezingamelani neekhemikhali); i-polyester + i-epoxy primer (iimeko zangaphandle ezinokugqwala okuphezulu)
Polypropylene vs Polyethylene
Thermoplastic vs Thermoset
