Cov ntsiab lus tseem ceeb ntawm kev xaiv thiab kev xaiv tshwj xeeb Thaum koj yuav tsum tau yuav cov log roj hmab, koj yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no: 1. Qhov hnyav uas lub log yuav tsum tau dais, lub log yuav tsum loj dua qhov hnyav no kom ua rau lub neej ua haujlwm ntawm lub log. lub log;2. Kev siv lub log yuav tsum du Siv cov roj hmab du, lub log tsis sib xws nrog cov hlau nplaum, thiab cov grooved hlau cores;3. Xaiv lub teeb roj hmab log rau lub teeb load-bearing log, thiab xaim roj hmab log rau hnyav hnyav;grooved hlau cores yuav tsum tau;4. Zoo Qhov kev xaiv ntawm lub log yuav tsum hloov tau yooj yim thiab nyuaj, txwv tsis pub nws yog ib qho yooj yim kom poob kua nplaum thiab degumming, thiab nws kim heev rau kev yuav thiab siv.Lub luag haujlwm hnyav yuav tsum muaj cov grooved hlau core thiab hlau nplaum, kom lub neej kev pab cuam yuav ntev thiab nws yuav pheej yig siv.Tsis muaj teeb meem dab tsi ntawm lub log tsis muaj elasticity thiab hardness, qhov zoo yuav tsis zoo.Cov yam ntxwv ntawm cov roj hmab log.
1. Thaum cov khoom siv roj hmab yog molded, lawv raug nias rau hauv siab thiab tsis tuaj yeem raug tshem tawm vim kev sib koom ua ke ntawm lub cev elastic.sib txawv los ntawm hom), Nws yuav siv sij hawm ib pliag kom calm down thiab stabilize.Yog li ntawd, thaum pib ntawm kev tsim cov khoom siv roj hmab, tsis hais cov mis los yog cov pwm, nws yog ib qho tsim nyog yuav tsum ua tib zoo xam thiab phim.Yog tias tsis yog, nws yooj yim ua rau cov khoom loj tsis ruaj khov, ua rau cov khoom tsis zoo.
2. Roj hmab yog kub-melt thiab thermosetting elastomer, thaum yas yog kub-melt thiab txias-teeb elastomer.Vim muaj ntau hom sulfides, qhov kub thiab txias rau molding thiab kho cov roj hmab kuj sib txawv heev, thiab tej zaum nws yuav cuam tshuam los ntawm kev hloov pauv huab cua thiab huab cua hauv tsev thiab av noo.Yog li ntawd, cov txheej txheem tsim khoom ntawm cov khoom siv roj hmab yuav tsum tau hloov kho me ntsis txhua lub sijhawm.Yog tsis yog, tej zaum yuav muaj qhov sib txawv ntawm cov khoom zoo.
