Munyika yekugadzirwa kwakarurama, kuvimbika kwezvikamu zvesimbi kunokosha. Kunyangwe zvikamu zvakagadziridzwa zvine hungwaru, kunyanya izvo zvinogadzirwa kuburikidza nekufa-kukanda kana upfu simbi, zvinogona kutambura nechakavanzika chikanganiso: micro-porosity. Aya ma microscopic pores uye kutsemuka mukati mezvinhu zvinogona kukonzeresa kutadza kwakashata, zvichikonzera kuvuza pasi pekumanikidzwa, kuparadza nzvimbo inopera, uye kukanganisa simba rechimiro. Apa ndipo panobuda vacuum impregnation seyakakosha uye yakaomesesa yekuisa chisimbiso mhinduro.
Pakati payo, vacuum impregnation isimba rakasimba-matanho matatu akagadzirirwa kubvisa zvachose porosity. Danho rekutanga rinosanganisira kuisa zvikamu mukamuri yakavharwa impregnation. Pombi yevacuum ine simba inobva yaburitsa mweya wese kubva mukamuri, panguva imwe chete ichikweva mweya wakavharirwa mukati me pores yechikamu. Danho rakakosha iri rinogadzira nzvimbo isina chinhu, yakagadzirira kuzadzwa.
Danho rechipiri rinotanga nekuunzwa kweakasarudzika fluid sealant, kana impregnation resin, mukamuri apo vacuum ichichengetwa. Iyo yakakosha dzvinyiriro musiyano pakati pevacuum mukati me pores uye mhepo iri pamusoro pemvura inomanikidza resin yakadzika mune yega micro-leak nzira, kuve nechokwadi chekupinda kwakazara. Pakupedzisira, vacuum inosunungurwa, uye zvikamu zvinosukwa. Nzira yekurapa, kazhinji kuburikidza nekupisa, yobva yaomesa zvachose resin mukati me pores, ichigadzira chisimbiso, chisimbiso chinobuda.
Mashandisirwo eiyi tekinoroji yakakura uye yakakosha. Mumaindasitiri emotokari uye aerospace, inonamira zvivharo zveinjini, dzimba dzekutapurirana, uye ma hydraulic manifolds, kuve nechokwadi chekuti vanokwanisa kumirisana nekumanikidza kwakanyanya pasina kubuda mvura. Uyezve, chinhu chinodiwa chepamusoro-mhando yekupedzisa. Pasina kunyura, zvinwiwa kubva pakuputira kana kupenda maitiro zvinogona kuvharirwa mumapores, gare gare kuwedzera uye kukonzera mablister kana "plating pops." Nekuvhara iyo substrate, vagadziri vanowana asina chaanopomerwa, akasimba machira pazvigadzirwa zvevatengi senge faucets uye emagetsi mudziyo dzimba.
Chinhu chakakosha, chisingagone kutaurirana chekushandisa vacuum impregnation system kuisirwa kwakakodzera kusefa. Izvi zvinhu zviviri zvinodiwa. Kutanga, iyo impregnation resin pachayo inofanira kuchengetwa yakachena. Particulate kusvibiswa kunogona kuvhara ma pores ayo maitiro anovavarira kuzadza. Naizvozvo, ma-in-line mafirita, anowanzo shandisa pleated polypropylene sefa cartridges ane ratings pakati pe1 kusvika 25 microns, anoiswa mu resin circulation loop kubvisa chero gels kana zvidimbu zvekunze.
Chechipiri, uye zvakangokosha, kuchengetedzwa kwepombi yevacuum. Iyo vacuum nharaunda inogona kukwevera zvinonyungudutsa kubva kune resin kana kukonzera maminetsi emvura madonhwe kuti aerosolize. Pasina zvakakwanainlet sefa, izvi zvinosvibisa zvaizoyamwa zvakananga mupombi yemafuta system. Izvi zvinotungamira kukurumidza emulsification, kushatisa, uye abrasive kupfeka pazvinhu zvemukati, zvichikonzera kudhura kunodhura, kazhinji kuchinja kwemafuta, uye kutadza kwepombi nguva isati yakwana. Sefa yevacuum inochengetedzwa zvakanaka inoshanda semuchengeti, ichiona kuti pombi inogara kwenguva refu uye kushanda kwayo kunoenderana.
Mukupedzisa, vacuum impregnation inopfuura nekure nyore yekuisa chisimbiso; inhanho yakakosha yekusimbisa nhanho inosimudzira kuita kwechigadzirwa, kuvimbika, uye aesthetics. Nekunzwisisa uye nekudzora zvine hungwaru maitiro-kusanganisira kuisirwa kwakakosha kwezvose resin uyevacuum pombi filters-Vagadziri vanogona kuendesa zvikamu zvinosangana nemhando yepamusoro yemhando uye kusimba.
