Cov ntawv txhuas-yas sib xyaw ua ke yog cov khoom siv kho kom zoo nkauj tshiab. Vim nws muaj zog kho kom zoo nkauj, muaj yeeb yuj, ruaj khov, lub teeb yuag thiab yooj yim ua, nws tau tsim kho sai thiab siv dav hauv tsev thiab txawv teb chaws.
Hauv lub qhov muag ntawm cov neeg tsis paub, kev tsim cov txhuas-yas composite board yog qhov yooj yim heev, tab sis qhov tseeb nws yog cov ntsiab lus siab heev ntawm cov khoom tshiab. Yog li ntawd, kev tswj xyuas zoo ntawm cov khoom vaj huam sib luag txhuas-yas composite muaj qee qhov teeb meem kev siv tshuab.
Cov hauv qab noyogCov yam tseem ceeb uas cuam tshuam rau 180 ° lub zog tev ntawm txhuas - yas sib xyawvaj huam sib luag:
Qhov zoo ntawm cov ntawv ci txhuas nws tus kheej yog ib qho teeb meem. Txawm hais tias qhov no yog ib qho teeb meem zais cia, nws tau pom tseeb hauv qhov zoo ntawm cov vaj huam sib luag txhuas-yas. Ntawm ib sab tes, nws yog cov txheej txheem kho cua sov ntawm txhuas. Ntawm qhov tod tes, qee cov txhuasvaj huam sib luagCov tuam txhab tsim khoom siv cov khib nyiab txhuas rov ua dua tshiab yam tsis muaj kev tswj hwm zoo. Qhov no yuav tsum tau kom cov chaw tsim khoom yas txhuas ua qhov kev ntsuam xyuas tag nrho ntawm cov khoom siv tsim khoom, tsim kom muaj kev sib cuag ua lag luam thiab xyuas kom meej tias cov khoom siv zoo tom qab txiav txim siab cov neeg cog lus tsim nyog.
Kev kho ua ntej ntawm txhuasvaj huam sib luagQhov zoo ntawm kev ntxuav thiab lamination ntawm txhuasvaj huam sib luagmuaj feem cuam tshuam ncaj qha rau qhov zoo ntawm cov yas txhuasvaj huam sib luag. Cov txhuasvaj huam sib luagYuav tsum tau ntxuav ua ntej kom tshem tawm cov roj av thiab cov khoom tsis huv ntawm qhov chaw, kom qhov chaw tsim cov txheej tshuaj ntom ntom, kom cov zaj duab xis polymer tuaj yeem tsim cov khoom sib txuas zoo. Txawm li cas los xij, qee lub tuam txhab tsim khoom tsis tswj hwm qhov kub, kev sib xyaw, lub sijhawm kho thiab cov kua dej hloov tshiab thaum lub sijhawm ua ntej kho, yog li cuam tshuam rau qhov zoo ntawm kev ntxuav. Tsis tas li ntawd, qee lub tuam txhab tsim khoom tshiab siv cov ntawv txhuas ncaj qha yam tsis muaj kev kho ua ntej. Tag nrho cov no yuav ua rau tsis zoo, qis 180 ° tev tawv lossis tsis ruaj khov ntawm cov khoom sib xyaw.
Xaiv cov khoom siv tseem ceeb. Piv nrog rau lwm cov yas, cov yeeb yaj kiab polymer sib txuas zoo tshaj plaws rau polyethylene, pheej yig, tsis muaj tshuaj lom thiab yooj yim rau kev ua. Yog li cov khoom siv tseem ceeb yog polyethylene. Txhawm rau kom txo cov nqi, qee lub tuam txhab me me xaiv PVC, uas muaj kev sib txuas tsis zoo thiab tsim cov pa phem thaum hlawv, lossis xaiv cov khoom siv rov ua dua PE lossis siv cov khoom siv PE sib xyaw nrog cov khoom siv hauv qab. Vim yog ntau hom PE, qib laus thiab lwm yam, qhov no yuav ua rau muaj qhov kub sib txawv, thiab qhov zoo ntawm qhov chaw sib xyaw kawg yuav tsis ruaj khov.
Xaiv zaj duab xis polymer. Zaj duab xis polymer yog ib hom khoom siv nplaum uas muaj cov yam ntxwv tshwj xeeb, uas yog qhov tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov khoom sib xyaw. Zaj duab xis polymer muaj ob sab thiab muaj peb txheej sib koom ua ke. Ib sab yog sib txuas nrog hlau thiab lwm sab yog sib txuas nrog PE. Txheej nruab nrab yog cov khoom siv PE. Cov yam ntxwv ntawm ob sab sib txawv kiag li. Muaj qhov sib txawv loj hauv tus nqi khoom siv ntawm ob sab. Cov khoom siv ntsig txog txhuasvaj huam sib luagCov chaw ua haujlwm yuav tsum tau xa tuaj thiab kim heev. Cov khoom sib xyaw nrog PE tuaj yeem tsim tau hauv Suav teb. Yog li ntawd, qee cov chaw tsim khoom yas zaj duab xis ua rau muaj kev ntxhov siab txog qhov no, siv cov khoom siv PE molten ntau, txiav cov ces kaum thiab khwv tau nyiaj ntau. Kev siv cov yas zaj duab xis yog kev taw qhia thiab pem hauv ntej thiab nraub qaum tsis tuaj yeem hloov pauv. Yas zaj duab xis polymer yog ib hom yas zaj duab xis uas lwj tag, yaj tsis tiav yuav ua rau muaj kev sib xyaw ua ke cuav. Lub zog thaum ntxov siab, lub sijhawm ntev, lub zog txo qis los ntawm huab cua, thiab txawm tias cov npuas lossis cov pos hniav tshwm sim.
