Qhov tshwm sim ntawm tsis yog - cov lauj kaub kib tau ua kom yooj yim rau tib neeg lub neej. Cov neeg tsis tas yuav txhawj xeeb txog kev hlawv nqaij thaum ua noj lossis ntses ua rau lub lauj kaub thaum kib.
Cov tsis yog - cov lauj kaub kib no muaj me ntsis ua nrog cov yias zoo tib yam; Qhov txawv tsuas yog tias sab hauv yog coated nrog ib txheej ntawm polytetrafluoroethylene (PTFE). Siv PTFE cov khoom cua sov zoo heev, cov khoom siv tshuaj lom neeg, thiab yooj yim - rau- huv si, qhov khoom siv hauv chav ua noj nrov tau tsim.
PTFE yog hailed li "King of Plastics" vim nws zoo heev tsis kam mus tshuaj corrosion thiab laus; Txawm tias aqua regia yog qhov nyuaj rau nws corrode.
Cov khoom siv yas zoo tib yam yog qhov yooj yim rau kev laus. Tej yam uas zoo li zoo thaum xub thawj yuav tsim cov kab nrib pleb lossis tawg tom qab peb mus rau tsib lossis kaum xyoo.
Txawm li cas los xij, cov khoom ua los ntawm "King of Plastics" tuaj yeem tawm sab nraum zoov, raug tshav ntuj thiab los nag, rau nees nkaum lossis peb caug xyoo yam tsis muaj kev puas tsuaj. Yog li ntawd, lawv tau siv dav hauv kev lag luam hauv tsev thiab tshuaj lom neeg.
Cov keeb kwm ntawm cov khoom tsis yog -cov lauj kaub kib hauv Suav teb tuaj yeem taug qab mus txog thaum xyoo 1970s. Lub sijhawm ntawd… Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Lub Teeb tau teeb tsa lub rooj sib tham txog kev siv thev naus laus zis ntawm cov khoom siv sab hauv thiab sab nraud enameled aluminium, koom nrog cov khoom lag luam txhuas, cov chaw tshawb fawb, thiab cov kws tshaj lij txawv teb chaws.
Tom qab lub rooj sib tham, lub ntsiab lus ntawm kev txhim kho tsis yog - cov lauj kaub kib tau raug tsa, ua rau ntau tshaj kaum lub tuam txhab tsim khoom lag luam aluminium pib tshawb fawb thiab txhim kho kev ua haujlwm ntawm cov tsis yog - cov lauj kaub kib. Ntau lub tuam txhab thoob plaws lub tebchaws tom qab tau xa tawm cov kab ntau lawm rau sab hauv thiab sab nraud enameled txhuas cov khoom lag luam los ntawm txawv teb chaws, nrog rau cov khoom lag luam txhua xyoo ntawm kwv yees li 20 lab lub lauj kaub, ntawm cov khoom xa tawm suav txog ntau dua 50%.
