PB kub thiab dej txias dej
Polybutene (PB) Yeeb Nkab yog qhov siab molecular inert polymer. PB resin yog cov khoom siv polymer los ntawm buthene- 1. Nws muaj qhov ceev tshwj xeeb ntawm 0.937 g / crystal, uas yog lub cev heterogeneous nrog kev hloov pauv. Nws zwm rau cov khoom lag luam siab ntawm cov khoom siv organic. Thiab muaj cov kub ua hauj, kav ntev, tshuaj lom neeg ruaj khov thiab muaj kuab.
Nws yog tasteless, tsis muaj tshuaj lom, tsw ntxhiab, muaj kub-resistant, thiab yog-xeb, thiab muaj lub neej ntev (50- 100
xyoo). Thiab nws muaj cov yam ntxwv ntawm kev laus ntev ntev. Nws yog ib qho ntawm feem ntau txiav cov khoom siv tshuaj lom neeg hauv ntiaj teb. Nws yog dav siv nyob rau hauv ntau lub teb chaws nyob hauv lub ntiaj teb. Thiab nws muaj lub koob npe nrov ntawm "kub hauv
Yas ".
Pb kub thiab dej txias yeeb nkab kev faib tawm
Cov khoom pov tseg cov kuab paug tsim tawm hauv kev lag luam semiconduct yog cov khoom siv ua kom zoo xws li stripping kua rau b6-1, stripping kua C01, thiab stripping kua p01. Cov khoom no yog siv rau hauv kev tsim cov kua siv lead ua cov panels, semiconductor ua ke sib xyaw ua ke thiab lwm yam kev ua haujlwm.

1.Nws yog lub teeb yuag, hloov tau yooj yim thiab yooj yim rau kev tsim. Qhov hnyav ntawm PB cov yeeb nkab yog li 1/5 ntawm qhov ntawm galvanized steel yeeb nkab. Nws yog hloov tau thiab yooj yim nqa. Qhov tsawg kawg yog khoov radius yog 6D (D: Yeeb Nkab Txheej Hlau). Nws tau txais kev vam meej melt kev twb kev txuas lossis kev sib txuas tshuab, uas yooj yim rau kev tsim kho.
2. Nws muaj cov txiaj ntsig zoo, tsis muaj tshuaj lom thiab tsis muaj mob. Vim tias nws lub siab molecular hnyav, nws cov qauv molecular yog ruaj khov. Nws tsis muaj tshuaj lom thiab tsis muaj kev phom sij thiab muaj lub neej pabcuam tsis muaj tsawg dua 50 xyoo tsis muaj ultraviolet hluav taws xob.
3.t muaj qhov zoo fromistance thiab kub ua kom tsis kam. Txawm nyob ntawm-20 ° C, nws tuaj yeem ua kom muaj kev pheej hmoo qis-kub cuam tshuam. Tom qab yaj, cov yeeb nkab rov qab rau nws cov qauv qub. Nyob rau hauv cov xwm txheej ntawm 100 ℃, txhua yam ntawm kev ua tau zoo tseem tuav tau zoo.
4.Nws muaj cov yeeb nkab du thiab tsis ntsuas. Piv nrog galvanized kav, nws tuaj yeem nce cov dej ntws los ntawm 30%.
5.Nws kho tau yooj yim. Thaum lub PB cov yeeb nkab raug faus, nws tsis tau sib khi rau cov pob zeb. Thaum nws ua puas, nws tuaj yeem kho tau sai sai los ntawm kev hloov cov yeeb nkab. Txawm li cas los xij, nws yog qhov zoo dua rau siv casing (yeeb nkab hauv cov yeeb nkab) txoj kev rau burying yas. Firstly, npog lub PB Yeeb Nkab nrog PVC ib-phab ntsa corrugated cov yeeb nkab, thiab tom qab ntawd faus nws, yog li yav tom ntej txij nkawm
tuaj yeem lav.
