Cam khwb cia hlau lauj kaub yog lub feem ntau nrov ua noj lauj kaub nyob rau hauv Tuam Tshoj vim nws lub zog siab, hlau replenishment, kev lag luam thiab practicality.Txawm li cas los xij, cam khwb cia hlau lauj kaub tam sim no nyob rau hauv kev ua lag luam yog tag nrho cov cam khwb cia hlau los yog siv dua hlau.Cov khoom tseem ceeb ntawm cam khwb cia hlau: carbon (C) = 2.0 txog 4.5%, silicon (Si) = 1.0 txog 3.0%.Txawm hais tias nws muaj qhov zoo ntawm tus nqi qis, zoo castability thiab txiav kev ua tau zoo, thiab siab saum npoo hardness, nws yog tsim los ntawm npua hlau los yog nws yog ncaj qha cam khwb cia los ntawm recycled steel.Ntxiv nrog rau ntau dua silicon thiab carbon cov ntsiab lus, nws kuj muaj phosphorus, sulfur, lead, cadmium, arsenic thiab lwm yam teeb meem rau tib neeg lub cev.Yog li nyob rau hauv cov txheej txheem ua noj, txawm hais tias lub lauj kaub hlau tuaj yeem ntxiv cov hlau, nws yooj yim rau precipitate cov teeb meem no thaum ntxiv cov hlau, tshwj xeeb tshaj yog cov hlau hnyav xws li txhuas, cadmium thiab arsenic yuav nkag mus rau tib neeg lub cev nrog zaub mov thiab sib sau ua ke dhau sijhawm.Nws yuav ua rau mob hnyav rau tib neeg lub cev.Piv txwv li, National Standard of the People's Republic of China "Hygienic Standard for Stainless Steel Tableware Containers" GB9684-88 tau ua ntau txoj cai ntawm lub cev thiab tshuaj indexes ntawm austenitic stainless hlau thiab martensitic stainless hlau.Txawm li cas los xij, vim tsis muaj lub teb chaws lossis cov qauv kev lag luam rau cov ntsuas kev huv ntawm cov hlau cookware, thiab cov kev txwv ntawm nws txoj kev tsim khoom, txhua tus neeg tsim khoom tsis tau tswj hwm lawv cov ntsuas kev huv.Tom qab kev soj ntsuam random, kev huv ntawm cov hlau cookware, tshwj xeeb tshaj yog cam khwb cia hlau cookware, nyob rau hauv kev ua lag luam Feem ntau lawv tsis ua raws li lub cev thiab tshuaj ntsuas ntawm stainless hlau.
Kuj tseem muaj qee lub lauj kaub hlau stamped los ntawm cov hlau phaj hauv kev ua lag luam, txawm hais tias cov ntsiab lus ntawm cov hlau hnyav hnyav tuaj yeem raug txwv los ntawm kev xaiv cov ntaub ntawv steel phaj, thiaj li tsis ua rau mob typhoid kub taub hau rau tib neeg lub cev.Txawm li cas los xij, cov ntsiab lus carbon ntawm cov hlau phaj feem ntau tsawg dua 1.0%, uas ua rau tsis tshua muaj zog thiab xeb yooj yim.Daim ntawv thov patent naj npawb 90224166.4 tawm tswv yim rau lub tsho loj-lub zog enamel rau sab nrauv ntawm cov lauj kaub hlau zoo tib yam;daim ntawv thov patent naj npawb 87100220 thiab 89200759.1 siv cov txheej txheem ntawm txheej txheej aluminium rau sab nrauv ntawm lub lauj kaub hlau los daws cov teeb meem xeb ntawm qhov chaw, tab sis cov txheej txheem no cais cov hlau cov khoom xyaw rau hauv kev sib cuag nrog cov khoom noj, thiab qhov zoo ntawm cov hlau tawg. nyob rau hauv lub lauj kaub hlau ploj.
Tsis tas li ntawd, hlau cookware ua los ntawm stamping thiab tsim ntawm steel phaj muaj ib tug denser cov ntaub ntawv qauv, yog li nws lub zog cia cov yam ntxwv thiab cov cua kub preservation yog phem tshaj cam khwb cia hlau cookware;thiab vim tias tsis muaj micropores ntawm qhov chaw, nws cov roj saum npoo av nqus thiab kev ua haujlwm cia kuj zoo dua li cov khoom siv hlau cam khwb cia.Tsis zoo cam khwb cia hlau cookware.Thaum kawg, hlau cookware ua los ntawm stamping thiab tsim ntawm steel phaj tsis tuaj yeem ua tiav cov nyhuv ua noj ntawm cam khwb cia hlau cookware vim tias nws nyuaj rau kev ua tiav cov thickness tsis sib npaug nrog cov tuab hauv qab thiab nyias npoo hauv nws ntu.
