Cov khob feem ntau siv yog khob dej, tab sis muaj ntau hom khob.Hais txog cov khoom siv khob, cov khoom siv yog khob khob, enamel khob, khob ceramic, khob yas, stainless hlau khob, ntawv khob, thermos khob, khob noj qab haus huv, thiab lwm yam. Yuav ua li cas xaiv lub khob dej nyab xeeb kom haum rau haus?
1. Yas khob: xaiv cov zaub mov qib yas
Cov khob yas yog nyiam los ntawm ntau tus neeg vim lawv cov duab hloov tau, xim ci, thiab cov yam ntxwv tsis ntshai ntawm kev poob.Lawv tsim nyog rau cov neeg siv sab nraum zoov thiab cov neeg ua haujlwm hauv chaw ua haujlwm.Feem ntau hais lus, hauv qab ntawm lub khob yas muaj lub cim, uas yog tus lej ntawm daim duab peb sab me me.Qhov ntau yog "05", uas txhais tau hais tias cov khoom ntawm lub khob yog PP (polypropylene).Lub khob ua los ntawm PP muaj qhov ua kom sov zoo, qhov taw tes melting yog 170 ° C ~ 172 ° C, thiab cov khoom siv tshuaj muaj zog kuj zoo.Ntxiv rau qhov raug corroded los ntawm concentrated sulfuric acid thiab concentrated nitric acid, nws yog ib qho ruaj khov rau lwm cov tshuaj reagents.Tab sis qhov teeb meem nrog lub khob yas zoo tib yam yog dav.Yas yog cov khoom siv tshuaj polymer.Thaum lub khob yas siv los sau cov dej kub los yog dej kub npau npau, cov polymer yog yooj yim los nag thiab yaj rau hauv dej, uas ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv tom qab haus.Ntxiv mus, sab hauv microstructure ntawm cov yas muaj ntau qhov pores, uas zais cov av, thiab cov kab mob yuav yug me nyuam yog tias nws tsis tau ntxuav kom zoo.Yog li ntawd, kev xaiv lub khob yas yog ib qho tseem ceeb heev rau kev xaiv cov khoom siv yas, thiab cov khoom noj-qib yas uas ua tau raws li cov qauv hauv tebchaws yuav tsum tau xaiv.Qhov ntawd yog cov khoom siv PP.
2. Ceramic khob: xaiv underglaze xim zoo li
Ceramic khob dej muaj yeeb yuj yog qhov zoo nkauj heev, tab sis qhov tseeb muaj qhov phom sij loj zais hauv cov xim ci.Sab hauv phab ntsa ntawm ib qho pheej yig xim xim ceramic khob feem ntau yog coated nrog ib txheej ntawm glaze.Thaum lub khob glazed tau ntim nrog dej kub los yog dej haus uas muaj kua qaub thiab alkalinity, qee cov txhuas thiab lwm cov hlau hnyav hnyav hauv cov glaze tau yooj yim precipitated thiab yaj rau hauv cov kua.Lub sijhawm no, thaum tib neeg haus cov kua nrog tshuaj lom neeg, tib neeg lub cev yuav raug mob.Thaum siv cov khob ceramic, nws yog qhov zoo tshaj plaws los siv lub khob xim ntuj.Yog tias koj tsis tuaj yeem tiv taus qhov kev ntxias ntawm cov xim, koj tuaj yeem ncav cuag thiab kov cov xim nto.Yog hais tias qhov saum npoo yog du, nws txhais tau hais tias nws yog xim underglaze lossis underglaze xim, uas yog qhov zoo;Tseem yuav muaj qhov tshwm sim ntawm kev poob tawm, uas txhais tau hais tias nws yog xim ntawm glaze, thiab nws yog qhov zoo tshaj kom tsis txhob yuav nws.
3. Cov khob ntawv: Cov khob ntawv pov tseg yuav tsum tau siv me ntsis
Tam sim no, yuav luag txhua tsev neeg thiab chav tsev yuav npaj ib lub khob ntawv tso quav tso tseg, uas yog siv los ntawm ib tus neeg thiab muab pov tseg tom qab siv, uas yog huv thiab yooj yim, tab sis xws li ib khob khob npog ntau yam teeb meem.Muaj peb hom ntawv khob ntawm kev ua lag luam: thawj tus yog ua los ntawm cov ntawv dawb, uas tsis tuaj yeem tuav dej thiab roj.Qhov thib ob yog ib lub khob uas siv quav ciab-coated.Ntev npaum li cov dej kub tshaj 40 ° C, cov quav ciab yuav yaj thiab tso cov carcinogenic polycyclic aromatic hydrocarbons.Hom thib peb yog daim ntawv-yas khob.Yog tias cov ntaub ntawv xaiv tsis zoo lossis cov txheej txheem kev ua haujlwm tsis zoo txaus, kev hloov pauv yuav tshwm sim thaum lub sijhawm txheej txheem ntawm polyethylene kub-melting los yog smearing ntawm daim ntawv khob, uas ua rau carcinogens.Txhawm rau kom cov tawv nqaij tawv thiab tawv tawv ntawm lub khob, cov yas yas ntxiv rau hauv cov khob ntawv.Kev tu cev tsis tuaj yeem lav tau yog tias qhov ntau npaum li cas los yog siv cov yas yas tsis raug cai.
4. iav: siv tau thiab muaj kev nyab xeeb los tiv thaiv kev tawg
Thawj qhov kev xaiv rau haus iav yuav tsum yog iav, tshwj xeeb tshaj yog rau cov neeg siv hauv chaw ua haujlwm thiab hauv tsev.Cov iav tsis yog tsuas yog pob tshab thiab zoo nkauj xwb, tab sis ntawm tag nrho cov ntaub ntawv ntawm cov iav, iav yog qhov zoo tshaj plaws thiab kev nyab xeeb tshaj plaws.Lub khob yog ua los ntawm inorganic silicates, thiab tsis muaj cov organic tshuaj thaum lub sij hawm tua.Thaum tib neeg haus dej lossis lwm yam dej haus los ntawm lub khob, lawv tsis tas yuav txhawj xeeb txog cov tshuaj uas qaug rau hauv lawv lub plab.;Thiab lub khob saum npoo yog du thiab yooj yim los ntxuav, thiab cov kab mob thiab cov av tsis yooj yim rau yug ntawm phab ntsa ntawm lub khob, yog li nws yog qhov noj qab haus huv thiab nyab xeeb tshaj plaws rau cov neeg haus dej ntawm lub khob.Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias lub khob yog ntshai tshaj plaws ntawm thermal expansion thiab contraction, thiab lub khob uas tsis tshua muaj kub yuav tsum tsis txhob ntim nrog dej kub tam sim ntawd kom tsis txhob tawg.
