Mokhoa oa tšebetso
1. Mocheso oa moqomo
Mocheso oa mocheso o sebelisoang ha o sebetsana le li-pellets tse matlafalitsoeng o lokela ho ba ka holimo ho 280 ° C. Sena ke hobane, ha mocheso o phahame, viscosity ea ho qhibiliha e tla fokotseha haholo, e le hore matla a ho kuta a sebetsang ho fiber a fokotsehe haholo.'Me ho robeha ha fiberglass haholo-holo ho etsahala karolong e qhibilihang ea extruder.hobane fiber ea khalase e kenngoa ho polymer e qhibilihisitsoeng, ho qhibiliha ho kopantsoe le fiber ea khalase ho phuthela fiber ea khalase, e phethang karolo ea ho tlotsa le ho sireletsa.Sena se fokotsa ho phatloha ho feteletseng ha li-fiber le ho roala ha li-screw le libarele, 'me se thusa ho hasana le ho ajoa ha likhoele tsa khalase ha ho qhibiliha.
2. Mocheso oa hlobo
Mokhoa oa ho hlōleha ha fiberglass ka hlobo ke haholo-holo hore mocheso oa hlobo o tlase haholo ho feta oa ho qhibiliha.Ka mor'a hore ho qhibiliha ho phalle ka har'a sekoti, lera le leqhoa le thehoa leboteng le ka hare hang-hang, 'me ka pholileng e tsoelang pele ea ho qhibiliha, lera le leqhoa le thehoa.Botenya ba khalase ea fiberglass bo ntse bo eketseha, e le hore karolo e bohareng e phallang e sa lefelloeng e be nyenyane le e nyenyane, 'me karolo ea fiber ea khalase e qhibilihisitsoeng e khomarela lera le leqhoa 'me qetello e 'ngoe e ntse e phalla ka ho qhibiliha, kahoo e etsa hore ho be le sekhahla se seholo. ho kuta ka matla holim'a khalase ea fiberglass e bakang ho robeha.Botenya ba lera le leqhoa kapa boholo ba lesela le phallang mahala le tla ama ka ho toba ho phalla ha ho qhibiliha le boholo ba matla a ho kuta, e leng se amang tekanyo ea tšenyo ea fiberglass.Botenya ba lera le leqhoa bo qala ho eketseha ebe bo fokotseha le sebaka se tsoang hekeng.Ke feela bohareng, botenya ba lera le leqhoa bo eketseha ka nako.Kahoo qetellong ea sekoti, bolelele ba fiber bo tla khutlela boemong bo bolelele.
