1, Txoj kev txiav txim siab zoo ntawm PB raj.
Tsuas yog thaum peb xyuas kom zoo ntawm PB raj tuaj yeem muab tso rau hauv kev siv nrog kev ntseeg siab. Yog li dab tsi yog txoj hauv kev los txiav txim nws qhov zoo?
Ib txoj hauv kev yooj yim yog qhov ua tau los soj ntsuam cov tsos ntawm PB kav dej. Cov kav dej zoo heev muaj qhov zoo nkauj, ua tiav cov logos, thiab cov npe ntawm cov khoom siv. Cov khoom lag luam qis tsis tuaj yeem ua qhov no. Vim tias cov raj zoo siv cov khoom siv raw zoo, thiab cov raj tsis zoo tsuas yog siv ib feem ntawm PB raw cov ntaub ntawv, muaj qhov sib txawv loj ntawm kev ua haujlwm ntawm ob. Ces nws yog los txiav txim nws toughness. Cov kav dej zoo zoo muaj qhov ua tau zoo thiab tuaj yeem khoov tau yooj yim rau hauv lub voj voog yam tsis muaj kev tawg, thaum cov kav dej tsis zoo yog nkig thiab tawg thaum lawv khoov. Nws tuaj yeem raug txiav txim los ntawm lub hauv paus ntsiab lus ntawm thermal expansion thiab contraction. Cov kav dej zoo tseem tuaj yeem tswj xyuas qhov nyuaj ntawm cov dej kub siab, thaum cov kav dej tsis zoo yog softened ntawm 60 degrees dej kub.
Cov raj zoo PB muaj lub sijhawm lav ntev dua, thaum cov khoom tsis zoo tuaj yeem kav ntev li 5-6 xyoo. Qhov no kuj yog ib lub hauv paus rau peb xaiv.

2, Dab tsi yog kev tsim kho cov kav dej PB?
Thaum thauj cov kav dej PB, thaum thauj khoom thiab stacking, lawv yuav tsum tau ua tib zoo sib dhos raws li qhov ntev ntawm lub laub, thiab thaum thauj khoom, lawv yuav tsum tau muab sib dhos kom zoo, thiab nws yog nruj me ntsis txwv tsis pub pov ncaj qha los ntawm lub laub.
Nws yog txwv tsis pub tso PB cov kav dej staggered nrog cov kav dej hluav taws xob thaum lawv hla cov kab teeb tsaus, hauv nruab nrab ntawm lub tsev, lossis ntawm lub qhov rooj. Thaum qhov kev tsim kho ib puag ncig kub qis dua 10 degrees Celsius thiab ze rau 5 degrees Celsius, lub sijhawm cua sov ntawm cov kav dej kub kub yuav tsum txuas ntxiv, thiab lub sijhawm hloov kho yuav tsum raug txo. Tsis txhob nias lossis tuav cov kav dej txuas. Thaum tsim nyog, npog cov khoom uas raug rau sab nraud, tshwj xeeb tshaj yog cov kav dej ntawm cov kav dej uas tsis raug kaw. Thaum lub ambient kub qis dua 10 degrees Celsius, kev tsim kho txuas ntxiv yuav cuam tshuam rau kev tsim kho kom zoo, yog li kev tsim kho yuav tsum tau ua raws li kev tsim kho lub caij ntuj no.
Vim yog cov khoom siv tshuaj lom neeg ntawm cov khoom siv nws tus kheej, cov yeeb nkab tau yooj yim tawg thaum raug rau sab nraud quab yuam. Yog li ntawd, nyob rau hauv lub caij ntuj no kev tsim kho, yuav tsum ceev faj thiab tsis txhob siv tsis tsim nyog sab nraud quab yuam rau cov yeeb nkab raug pov, poob, dov, dragged, los yog smashed.
