Chifukwa chiyani magwiridwe antchito a pulasitiki ndi abwino kuposa azitsulo
1. Chiyembekezo cha chitukuko cha matumba apulasitiki
Pakali pano, makasitomala ambiri ndi pa wokonzeka kusankha zitsulo zokhala ndi zida.Ndipotu, pamene zitsulo zapulasitiki sizinapangidwe, zitsulo zazitsulo zinkagwiritsidwa ntchito nthawi zonse ngati zipangizo zamakono. Koma mpaka pano, magwiridwe antchito a pulasitiki adzakhala abwino komanso abwino mtsogolo.
2.Pulasitiki kubala zipangizo ndi ubwino
Tmtengo wake wopanga pulasitiki ndi wotsika kuposa wazitsulo zazitsulo, ndipo mitundu yosiyanasiyana ya pulasitiki ikukulirakulira ndiamagwiritsidwa ntchito m'mafakitale ambiri, zinthu wamba pulasitikindi nayiloni, polytetrafluoroethylene, polyethylene ndi PEEK.
The matumba apulasitiki is kusinthasintha, chuma ndi ukhondo .Pali zida zambiri zotsika mtengo zomwe zingagwiritsidwe ntchito zosiyanasiyana.Ma bearing a pulasitiki nthawi zambiri amapangidwa ndi ma thermoplastic alloys okhala ndi fiber matrix ndi mafuta olimba, omwe amakhala ndi mphamvu zabwino kwambiri komanso kutsika kwapang'onopang'ono kosasinthasintha.
3. Ndi ntchito yabwino yotani ya zitsulo zapulasitiki ?
(1) Kudzipaka mafuta
Pulasitiki's chibadwa, mafuta mayendedwe, amachepetsa kuchedwa kuyamba ndi kusunga dera laukhondo.Kaching'ono kakang'ono kameneka kamakhala kovala koyambirira ndipo kamakhala ndi gawo lopaka mafuta, koma kusintha kwa kubereka komweko kunganyalanyazidwe.Izi zimapangitsanso kuti zitsulo zapulasitiki zikhale zoyenera kugwiritsa ntchito chakudya, chifukwa FDA imaletsa kwambiri kugwiritsa ntchito mafuta m'makina opanga zakudya.Kuonjezera apo, ngakhale fumbi ndi tinthu tating'onoting'ono timamatira ku mafuta odzola ndikupanga dothi, chifukwa cha zitsulo zapulasitiki, tinthu tating'onoting'ono tating'onoting'ono timangoyikidwa muzitsulo ndipo sizidzakhudza ntchitoyo.
(2) Opaleshoni yotsika komanso kutentha kwambiri
Zonyamula pulasitiki zimatha kugwira ntchito mosalekeza pa kutentha kulikonse pakati pa - 4° c ndi 260° C ndipo imatha kupirira kutentha kwambiri mpaka 600° F. The pulasitiki bushing akhoza kukhala amphamvu ngati zitsulo bushing, koma kubereka khoma ndi lopyapyala, nthawi zambiri 0.0468 "- 0.0625" wandiweyani.Makoma ang'onoang'ono amapereka kutentha kwabwinoko, zomwe zimapangitsa kuti pakhale ntchito zambiri komanso kuchepa kwa kuvala.Kuphatikiza apo, makoma owonda amakhala opepuka komanso osapunduka, kuwapangitsa kukhala oyenera kugwiritsa ntchito omwe ali ndi vuto la kulemera.
(3) Kuchita kwa chilengedwe
Chifukwa cha kulemera kopepuka kwa pulasitiki, zonyamula pulasitiki ndizowotcha mafuta.Zovala zapulasitiki sizifuna zokutira zowonjezera kapena zowonjezera kuti zipange zotsatira zomwezo monga zigawo zachitsulo zomwe zimaphatikizidwa ndi zinthu zovulaza.Kuphatikiza apo, kupanga pulasitiki kumafuna mafuta pafupifupi 10-15% poyerekeza ndi aluminium kapena chitsulo chofanana.
(4) Kukana mankhwala abwino
Zimbalangondo za pulasitiki nthawi zambiri zimagonjetsedwa ndi mankhwala ndi zinthu zosiyanasiyana kusiyana ndi zitsulo zachitsulo, ndipo zimagonjetsedwa ndi zokwawa ndi kuvala kwa zitsulo zachitsulo.Izi zimathandiza kuti ma coefficient awo ang'onoang'ono azikangana ndikuyenda bwino popanda kusokoneza pang'ono.
(5) Kusamalira kwaulere
Sankhani pulasitiki yolondola molingana ndi malo omwe mumagwiritsa ntchito, ndipo mayendedwe ake amatha kukana dzimbiri pakapita nthawi.Pambuyo pa kukhazikitsa, kunyamula pulasitiki kumakhala ndi moyo wautali wautumiki ndipo sikuyenera kusinthidwa.Zimbiri zimatha kupangitsa kuti zitsulo zazitsulo zizizizira bwino, zomwe zimapangitsa kuti zikhale zosatheka kuzichotsa popanda kuzidula.Zonyamula pulasitiki ndizosavuta kuchotsa.
(6) Mtengo wotsika wapulasitiki
Mapulasitiki ambiri ndi otchipa kuposa zitsulo.Choncho zitsulo zapulasitiki ndi matabwa apulasitiki zingachepetse ndalama
