1. PERT Yeeb Nkab
PERT raj tsis ntxiv cov tshuaj lom hauv kev tsim khoom, nws yog lub teeb, nws yooj yim rau kev thauj mus los, thiab nws qhov yooj yim kuj zoo, yog li tsis txhob preheat nws. Lub zog bending zog kuj zoo heev, thiab qhov kub thiab txias tsis kam ntawm cov yeeb nkab no kuj zoo heev. Hauv kev tsim kho lub caij ntuj no, nws tuaj yeem tiv taus Frost, thiab lub sijhawm ua haujlwm tuaj yeem ncav cuag ntau dua 50 xyoo.
2. Aluminium yeeb nkab
Qhov no zoo ntawm aluminium yas raj yog ua los ntawm txhuas raj tub ntxhais thiab polythermal fusion. Nws tuaj yeem hais tau tias qhov no yog hom tsis muaj tshuaj lom, tsis qab, thiab cuam tshuam-resistant. Lub zog ntawm lub raj tub ntxhais yog siab dua li ntawm aluminium alloy, thiab lub raj lub cev kuj yog lub teeb thiab yooj yim rau cov neeg ua haujlwm. Nws tseem tuaj yeem khoov rau hauv txhua lub tsev kho kom zoo nkauj, thiab nws tuaj yeem siv tau li ntawm 50 xyoo.
3. PB cev
PB yeeb nkab muaj qhov kub thiab txias tsis kam. Nws tuaj yeem hais tias nws kuj tsis muaj tshuaj lom thiab tsis qab. Nyob rau tib lub sijhawm, nws kuj muaj cov khoom tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev kub siab. Nyob rau hauv lub tsev, yuav tsis muaj deterioration, lub sij hawm siv yuav ua tau raws li lub sij hawm ntawm lub tsev, thiab tus nqi yuav siab dua.
