Compression Molding
Compression molding inzira yekuumba iyo preheated polymer inoiswa mugomba rakavhurika, rinopisa. Iyo mold inozovharwa nepamusoro plug uye yakatsikirirwa kuitira kuti zvinhu zvibatane nenzvimbo dzese dze mold.
Iyi nzira inokwanisa kugadzira zvikamu zvine huwandu hwakawanda hwehurefu, ukobvu, uye kuoma. Zvinhu zvainoburitsa zvakare zvine simba rakawanda, zvichiita kuti ive nzira inoyevedza kune akati wandei maindasitiri.
Thermoset composites ndiyo yakajairika mhando yezvinhu zvinoshandiswa mukumanikidza kuumbwa.
Matanho mana Makuru
Pane matanho mana makuru kune thermoset composite compression molding process:
- Simba rakakwirira, maviri chikamu chesimbi chishandiso chinogadzirwa chinonyatsoenderana nehukuru hunodiwa kugadzira chikamu chinodiwa. Chishandiso chacho chinobva chaiswa muchitsikirira uye chinopisa.
- Iyo inosanganiswa inodiwa inofanoumbwa kuita chimiro chechishandiso. Pre-forming inhanho yakakosha inobatsira kuvandudza mashandiro echikamu chakapedzwa.
- Chikamu chekare-chakagadzirwa chinopinzwa muhutu hunopisa. Chishandiso chinobva chamanikidzwa pasi pekumanikidzwa kwakanyanya, kazhinji kubva pa800psi kusvika 2000psi (zvichienderana nekukora kwechikamu uye rudzi rwezvinhu zvinoshandiswa).
- Chikamu chinobviswa kubva pachishandiswa mushure mekumanikidzwa kusunungurwa. Chero resin inopenya yakatenderedza mipendero inobviswa zvakare panguva ino.
Zvakanakira Compression Molding
Compression molding inzira yakakurumbira nekuda kwezvikonzero zvakati. Chikamu chemukurumbira waro chinobva mukushandisa kwayo macomposites epamusoro. Zvishandiso izvi zvinenge zvine simba, kuoma, kureruka, uye kushingirira mukuora kupfuura masimbi, zvichiita kuti pave nezvinhu zvepamusoro. Vagadziri vakajaira kushanda nenhengo dzesimbi vanoona kuti zviri nyore kwazvo kushandura chinhu chakagadzirirwa simbi kuita chikamu chekumanikidza. Nekuti zvinokwanisika kuenzanisa simbi chikamu geometry nehunyanzvi uhu, mumamiriro mazhinji munhu anogona kungodonha-mukati uye kutsiva chikamu chesimbi zvachose.
