Izinkomishi ezisetshenziswa kakhulu izinkomishi zamanzi, kodwa kunezinhlobo eziningi zezinkomishi.Ngokuphathelene nezinto zenkomishi, ezivamile ziyizinkomishi zeglasi, izinkomishi zoqweqwe lwawo, izinkomishi ze-ceramic, izinkomishi zepulasitiki, izinkomishi zensimbi engagqwali, izinkomishi zephepha, izinkomishi ze-thermos, izinkomishi zezempilo, njll. Indlela yokukhetha inkomishi yamanzi ephephile efanelekile ukuphuza?
1. Inkomishi yepulasitiki: khetha ipulasitiki yezinga lokudla
Izinkomishi zepulasitiki zithandwa abantu abaningi ngenxa yokushintsha kwabo, imibala ekhanyayo, nezici zokungesabi ukuwa.Zifaneleka kakhulu kubasebenzisi bangaphandle nabasebenzi basehhovisi.Ngokuvamile, phansi kwenkomishi yepulasitiki kunophawu, okuyinombolo ekunxantathu omncane.Okuvamile ngu-“05″, okusho ukuthi impahla yenkomishi yi-PP (polypropylene).Inkomishi eyenziwe nge-PP inokumelana nokushisa okuhle, indawo yokuncibilika ingu-170 ° C ~ 172 ° C, futhi izakhiwo zamakhemikhali azinzile.Ngaphezu kokugqwala yi-sulfuric acid egxilile kanye ne-nitric acid egxilile, izinzile uma kuqhathaniswa namanye ama-reagents amakhemikhali.Kodwa inkinga ngezinkomishi zepulasitiki ezivamile isabalele.Ipulasitiki iyi-polymer chemical material.Uma inkomishi yepulasitiki isetshenziselwa ukugcwalisa amanzi ashisayo noma amanzi abilayo, i-polymer idonswa kalula futhi incibilike emanzini, okuyingozi empilweni yomuntu ngemva kokuphuza.Ngaphezu kwalokho, i-microstructure yangaphakathi yepulasitiki inezimbotshana eziningi, ezifihla ukungcola, futhi amagciwane azozala uma engahlanzwa kahle.Ngakho-ke, ukukhethwa kwezinkomishi zepulasitiki kubaluleke kakhulu ekukhethweni kwezinto zepulasitiki, futhi amapulasitiki ebanga lokudla ahlangabezana nezindinganiso zikazwelonke kufanele akhethwe.Lokho yi-PP material.
2. Inkomishi ye-Ceramic: khetha nombala ocwebezelayo
Izinkomishi zamanzi ze-ceramic ezimibalabala ziyathopha kakhulu, kodwa empeleni kunezingozi ezinkulu ezifihliwe kulawo mapende agqamile.Udonga lwangaphakathi lwenkomishi ye-ceramic enombala engabizi ngokuvamile lumbozwa ungqimba lwe-glaze.Uma inkomishi ecwebezelisiwe igcwaliswa ngamanzi abilayo noma iziphuzo ezine-asidi ephezulu ne-alkalinity, enye i-aluminium nezinye izakhi ezinobuthi zensimbi esindayo ku-glaze ziwana kalula futhi zincibilikiswe oketshezini.Ngalesi sikhathi, lapho abantu bephuza uketshezi olunamakhemikhali, umzimba womuntu uzolimala.Uma usebenzisa izinkomishi ze-ceramic, kungcono ukusebenzisa izinkomishi zombala wemvelo.Uma ungakwazi ukumelana nesilingo sombala, ungakwazi ukufinyelela futhi uthinte indawo yombala.Uma ubuso bubushelelezi, kusho ukuthi umbala we-underglaze noma umbala we-underglaze, ophephile uma kuqhathaniswa;Kuzophinde kube nesenzakalo sokuwa, okusho ukuthi umbala on-glaze, futhi kungcono ukuthi ungayithengi.
3. Izinkomishi zephepha: Izinkomishi zephepha ezilahlwayo kufanele zisetshenziswe kancane
Njengamanje, cishe yonke imindeni kanye neyunithi izolungisa inkomishi yephepha lasendlini yangasese elahlayo, esetshenziswa umuntu oyedwa futhi ilahlwe ngemva kokusetshenziswa, okuhlanzekile futhi elula, kodwa indebe enjalo evamile ifihla izinkinga eziningi.Kunezinhlobo ezintathu zezinkomishi zephepha emakethe: eyokuqala yenziwe ngekhadibhodi elimhlophe, elingakwazi ukugcina amanzi namafutha.Okwesibili inkomishi yephepha eboshwe nge-wax.Uma nje izinga lokushisa lamanzi lidlula u-40°C, i-wax izoncibilika futhi ikhiphe ama-carcinogenic polycyclic aromamatic hydrocarbons.Uhlobo lwesithathu yizinkomishi ze-paper-plastic.Uma izinto ezikhethiwe zingezinhle noma ubuchwepheshe bokucubungula bunganele ngokwanele, izinguquko zokuqhekeka zizokwenzeka ngesikhathi senqubo ye-polyethylene eshisayo-encibilika noma egcotshwe ezinkomishini zephepha, okuholela kuma-carcinogens.Ukuze ukwandise ukuqina nokuqina kwezinkomishi, ama-plasticizers anezelwa ezinkomishini zephepha.Izimo zokuhlanzeka azinakuqinisekiswa uma umthamo uphezulu kakhulu noma kusetshenziswa amapulasitiki angekho emthethweni.
4. Ingilazi: iyasebenza futhi iphephile ukuvikela ukuqhuma
Inketho yokuqala yokuphuza izibuko kufanele ibe ingilazi, ikakhulukazi kubasebenzisi behhovisi nasekhaya.Ingilazi ayigcini nje ngokusobala futhi inhle, kodwa phakathi kwazo zonke izinto zengilazi, ingilazi iyona enempilo futhi ephephile kakhulu.Ingilazi yenziwe ngama-silicates angaphili, futhi ayinawo amakhemikhali aphilayo ngesikhathi sokudubula.Uma abantu bephuza amanzi noma ezinye iziphuzo engilazini, akudingekile ukuba bakhathazeke ngokuthi amakhemikhali aphuzwa esiswini sabo.;Futhi indawo yengilazi ibushelelezi futhi kulula ukuyihlanza, futhi amagciwane nokungcola akulula ukuzalela odongeni lwenkomishi, ngakho kunempilo futhi kuphephe kakhulu ukuthi abantu baphuze amanzi engilazini.Kodwa-ke, kufanele kuqashelwe ukuthi ingilazi yesaba kakhulu ukwanda nokunciphisa okushisayo, futhi ingilazi enokushisa okuphansi kakhulu akufanele igcwaliswe ngamanzi ashisayo ngokushesha ukuze ivimbele ukuthi ingaqhumi.
