Cov nplaum yog dab tsi?
Lub ntiaj teb no yog ua los ntawm cov ntaub ntawv. Thaum ob yam khoom siv yuav tsum tau sib xyaw ua ke, ntxiv rau qee txoj kev siv tshuab, feem ntau xav tau cov txheej txheem sib txuas. Cov nplaum yog cov tshuaj uas siv ob qho kev cuam tshuam lub cev thiab tshuaj lom neeg los sib xyaw ob yam khoom zoo sib xws lossis sib txawv. Lawv muab faib ua ob pawg: cov nplaum organic thiab cov nplaum inorganic. Hauv kev nkag siab dav dav, kev vuam hlau thiab cement yog txhua daim ntawv thov sib txuas.
Hom nplaum
Daim ntawv tseem ceeb ntawm cov nplaum
Daim ntawv tseem ceeb ntawm kev siv tshuab adhesion:
1. Kev sib txuas ntawm cov qauv:
Cov nplaum rau cov qauv yog nyob rau hauv qhov chaw sib txuas nrog lub zog sib txuas zoo heev, uas tuaj yeem hloov cov vuam, ntsia hlau, daim kab xev, thiab cov khoom siv sib txuas ib txwm muaj. Ua rau cov nplaum rau cov qauv muaj ntau qhov zoo, lub zog ntawm cov qauv ntawm cov qauv muaj zog heev, thiab kev faib tawm yuav tsum tau muab faib.
Qhov feem ntau txo qhov kev qaug zog ntawm qhov kev xav tau tsim nyog thiab txhim kho lub neej qaug zog ntawm lub rooj sib txoos.
2. Txheej:
Nws yog ib txheej tshwj xeeb uas phim, uas tiv thaiv lub phaj kab thiab nws cov khoom siv cuam tshuam los ntawm kev puas tsuaj ntawm qhov xwm txheej phem. Nyob rau hauv cov xwm txheej ua tau zoo, xws li tshuaj lom neeg, kev co, plua plav, ntsev pos huab, av noo thiab kub, lub rooj tsavxwm Circuit Court yuav tsim teeb meem xws li xeb, mos, deformation, thiab pwm, uas ua rau lub Circuit Court tsis ua haujlwm.
Peb txheej xim tiv thaiv rau ntawm qhov chaw ntawm lub rooj tsavxwm, tsim cov yeeb yaj kiab tiv thaiv peb txheej (peb txheej tiv thaiv xa mus rau cov dej noo, cov ntsev tsis muaj pos huab, thiab cov pwm).
3. Cog qoob loo:
Cov khoom siv rau cog paj, tseem hu ua cov neeg sawv cev rau cog paj lossis cov kua nplaum rau cog paj, hais txog kev cais cov voj voog lossis cov xov hlau ntawm cov dej noo, cov pa phem thiab lwm yam tshuaj lom, thiab tiv thaiv lawv ntawm kev ntxhov siab thermal lossis kev ntxhov siab mechanical.
Tib lub sijhawm, nws txhim kho nws cov kev ua haujlwm rwb thaiv tsev thiab yog cov khoom siv tiv thaiv kev sib khi uas nchuav rau hauv lub voj voog lossis cov xov hlau.
4. Kev sib txuas thiab kev kaw:
Tus qauv tsim nws tus kheej tsis yog tsim los ua haujlwm ruaj khov hauv kev co lossis qhov chaw nyuaj, yog li ntawd cov nplaum yog qhov xav tau los txhim kho kev ruaj khov ntawm tus qauv thiab los txuas qee qhov chaw nrog cov nplaum. Nyob rau hauv qhov xwm txheej ib txwm muaj, nws tsis yooj yim sua kom cov nplaim ntawm ob yam khoom sib cuag tag nrho. Txhawm rau tiv thaiv cov pa dej, hmoov av, thiab lwm yam kom tsis txhob nkag mus, thiab kom tiv thaiv cov khoom sab hauv kom tsis txhob nkag mus, qee yam khoom yuav tsum tau sau qhov sib txawv kom ua tiav 100% qhov sib txawv. Qhov no yog lub foob.
Daim ntawv thov teb
Cov nplaum tau nkag mus rau hauv kev lag luam niaj hnub thiab lub neej txhua hnub. Nws tuaj yeem hais tias txhua qhov chaw uas tib neeg nyob, tsis muaj cov khoom nplaum thiab cov thev naus laus zis nplaum. Nws muab cov khoom siv tes ua tshiab thiab siv tau rau kev lag luam thiab tsim lub neej muaj yeeb yuj rau tib neeg. Txais tos txhua tus los xaiv cov khoom Siway, uas yuav muab kev paub sib txawv rau koj!
