PB Cov Yeeb Nkab Dej Kub thiab Txias
Kev Taw Qhia Txog Cov Yeeb Nkab Dej Kub Thiab Txias PB
Cov yeeb nkab Polybutene (PB) yog ib qho polymer inert siab molecular. PB resin yog ib yam khoom polymer synthesized los ntawm butene-1. Nws muaj qhov ceev tshwj xeeb ntawm 0.937 g / cm3 siv lead ua, uas yog lub cev heterogeneous nrog kev ywj pheej. Nws yog cov khoom siv high-tech ntawm cov khoom siv organic tshuaj. Thiab muaj kev tiv taus kub siab, ruaj khov, tshuaj lom neeg ruaj khov thiab plasticity. Nws tsis muaj saj, tsis muaj tshuaj lom, tsis muaj ntxhiab, muaj qhov kub ntawm -30 ° C txog + 100 ° C, thiab yog txias-resistant, kub-resistant, siab-resistant, tsis xeb, tsis corrosive, tsis-scaling, thiab muaj lub neej ntev (50-100 xyoo). Thiab nws muaj cov yam ntxwv ntawm kev tiv taus kev laus mus sij hawm ntev. Nws yog ib qho ntawm cov khoom siv tshuaj lom neeg tshaj plaws hauv ntiaj teb. Nws yog siv dav hauv ntau lub tebchaws hauv ntiaj teb. Thiab Nws muaj lub koob npe nrov ntawm "kub hauv yas".
Cov kav dej txias thiab dej kub PB (polybutylene) zoo muaj tag nrho 24 yam khoom. Muab faib ua 4 yam lus qhia los ntawm dnl6 txog dn32. Raws li cov yeeb nkab series, nws muab faib ua rau series: S10, S8, S6.3, S5, S4 thiab 3.2.
Kev faib tawm ntawm PB Cov Yeeb Nkab Kub thiab Txias
Cov kuab tshuaj organic pov tseg uas tsim tawm hauv kev lag luam semiconductor raug kho thiab rov ua dua tshiab raws li cov txheej txheem sib xws los ntawm lub cuab yeej kho kom zoo los tsim cov khoom xws li kua stripping B6-1, kua stripping C01, thiab kua stripping P01. Cov khoom no feem ntau yog siv rau hauv kev tsim cov kua siv lead ua zaub, semiconductor integrated circuits thiab lwm yam txheej txheem.
Cov yam ntxwv ntawm PB Cov Yeeb Nkab Dej Kub thiab Txias
1. Nws yog lub teeb yuag, yoog tau thiab yooj yim rau kev tsim kho. Qhov hnyav ntawm PB yeeb nkab yog li 1/5 ntawm cov yeeb nkab galvanized steel. Nws yog qhov yoog tau thiab yooj yim rau kev nqa. Qhov tsawg kawg nkaus khoov vojvoog yog 6D (D: yeeb nkab sab nraud txoj kab uas hla). Nws siv kev sib txuas kub yaj lossis kev sib txuas tshuab, uas yooj yim rau kev tsim kho.
2. Nws muaj lub zog ruaj khov, tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij. Vim nws qhov hnyav molecular siab, nws cov qauv molecular ruaj khov. Nws tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij thiab muaj lub neej ua haujlwm tsawg kawg 50 xyoo yam tsis muaj teeb meem ultraviolet.
3.t muaj kev tiv thaiv zoo rau te thiab kub. Txawm tias nyob rau ntawm -20 ° C, nws tuaj yeem tswj tau qhov kub qis qis zoo tiv thaiv kev cuam tshuam. Tom qab yaj, cov yeeb nkab rov qab mus rau nws cov duab qub. Nyob rau hauv qhov xwm txheej ntawm 100 ℃, txhua yam ntawm kev ua tau zoo tseem khaws cia zoo.
4. Nws muaj cov phab ntsa yeeb nkab du thiab tsis loj. Piv nrog cov yeeb nkab galvanized, nws tuaj yeem ua rau dej ntws ntau dua 30%.
5. Nws yooj yim kho. Thaum lub yeeb nkab PB raug faus, nws tsis sib txuas nrog cov pob zeb. Thaum nws puas lawm, nws tuaj yeem kho tau sai los ntawm kev hloov lub yeeb nkab. Txawm li cas los xij, nws zoo dua los siv txoj kev casing (yeeb nkab hauv yeeb nkab) rau kev faus cov yeeb nkab yas. Ua ntej, npog lub yeeb nkab PB nrog PVC ib phab ntsa corrugated, thiab tom qab ntawd faus nws, kom kev saib xyuas yav tom ntej tuaj yeem lav.
