Taw qhia
PU pob zeb yog cov khoom siv nrov siv hauv kev tsim kho, tsev kho kom zoo nkauj, thiab ntau yam kev lag luam. Nws yog lub npe hu rau nws durability, tsis kam mus rau huab cua, thiab yooj yim ntawm txij nkawm. PU pob zeb kuj tseem muaj nuj nqis rau nws qhov kev zoo nkauj zoo nkauj, vim nws tuaj yeem ua raws li cov khoom siv ntuj tsim xws li pob zeb thiab cib, ntawm ib feem ntawm tus nqi. Tab sis dab tsi yog PU pob zeb ua los ntawm? Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv kev tshawb fawb tom qab no ntau yam khoom, sib tham txog nws muaj pes tsawg leeg, zog, thiab siv.
PU pob zeb yog dab tsi?
PU (polyurethane) pob zeb yog cov khoom siv dag zog uas yog tsim los ntawm kev sib txuas ntawm polyurethane resin nrog ntau cov khoom ntim thiab cov xim. Polyurethane yog ib hom polymer uas yog tsim los ntawm reacting diisocyanate, feem ntau methylene diphenyl diisocyanate (MDI), nrog ib tug polyol, xws li ib tug polyester los yog polyether. Cov txiaj ntsig ntawm polyurethane resin yog tom qab ntawd tov nrog cov khoom ntim, xws li cov pob zeb hauv av lossis xuab zeb, thiab cov xim xim, los tsim cov khoom uas zoo li thiab zoo li lub pob zeb ntuj.
Kev sib xyaw ntawm PU pob zeb
Cov muaj pes tsawg leeg ntawm PU pob zeb tuaj yeem sib txawv nyob ntawm cov chaw tsim khoom thiab cov khoom xav tau ntawm cov khoom kawg. Txawm li cas los xij, feem ntau PU pob zeb khoom muaj xws li polyurethane resin, muab tub lim, thiab pigments. Cov polyurethane resin feem ntau yog ob feem uas sib xyaw ua ke ua ntej thov. Thawj ntu muaj cov diisocyanate, thaum thib ob muaj cov polyol. Thaum ob qhov chaw sib xyaw ua ke, cov tshuaj lom neeg tshwm sim uas tsim cov polyurethane resin.
Cov fillers siv hauv PU pob zeb kuj tuaj yeem sib txawv, tab sis lawv feem ntau yog ua los ntawm cov hmoov zoo los yog granules ntawm pob zeb, xws li limestone lossis quartz. Cov fillers no ntxiv rau polyurethane resin los muab cov khoom nws zoo nkauj, hnyav, thiab lub zog. Tus nqi ntawm cov muab tub lim siv tuaj yeem sib txawv raws li qhov xav tau ntawm cov khoom kawg. Piv txwv li, yog tias cov chaw tsim khoom xav tsim lub teeb PU pob zeb, lawv yuav siv cov muab tub lim tsawg dua, thaum cov khoom hnyav dua yuav xav tau ntau dua.
Pigments kuj ntxiv rau qhov sib tov kom muab PU pob zeb nws cov xim. Cov xim no tuaj yeem muaj los ntawm cov xim zoo nkauj ntawm xim av, xim liab, thiab grey, mus rau ntau cov xim zoo li xiav lossis ntsuab. Tus nqi ntawm cov xim siv kuj tuaj yeem sib txawv raws li qhov xav tau xim siv.
Cov khoom ntawm PU pob zeb
PU pob zeb muaj ntau yam khoom uas ua rau nws tsim nyog siv rau hauv kev tsim kho, kho kom zoo nkauj hauv tsev, thiab lwm yam lag luam. Qee yam ntawm cov khoom no muaj xws li:
- Durability: PU pob zeb paub txog nws lub peev xwm tiv taus huab cua thiab lwm yam ib puag ncig. Nws tiv taus UV hluav taws xob, ya raws, thiab kev loj hlob ntawm cov kab mob fungal, ua rau nws zoo tagnrho rau kev siv sab nraum zoov.
- Lub teeb yuag: piv rau cov pob zeb ntuj, PU pob zeb yog qhov sib dua, ua rau nws yooj yim dua los tuav thiab nruab. Qhov no tuaj yeem txo tus nqi ntawm kev tsim kho thiab kev thauj mus los.
- Kev zoo nkauj zoo nkauj: PU pob zeb tuaj yeem ua raws li qhov zoo nkauj thiab zoo nkauj ntawm cov pob zeb ntuj, ntawm ib feem ntawm tus nqi. Nws tseem tuaj yeem raug molded rau hauv cov duab sib txawv thiab qhov ntau thiab tsawg, tso cai rau kev tsim kom yooj yim dua.
- Kev saib xyuas yooj yim: PU pob zeb yog ib qho yooj yim los ntxuav thiab tswj, tsuas yog yuav tsum tau ntxuav ib ntus nrog xab npum thiab dej. Nws tsis xav tau kev sib khi lossis lwm yam kev kho zoo li ntuj pob zeb.
- Hluav taws kub tsis kam: PU pob zeb tiv taus hluav taws, ua rau nws zoo tagnrho rau siv rau thaj chaw uas muaj kev kub ntxhov.
- Insulating zog: PU pob zeb muaj cov khoom siv insulating, ua rau nws zoo tagnrho rau siv hauv cov tsev uas muaj zog.
Kev siv PU pob zeb
PU pob zeb yog siv ntau yam kev siv, suav nrog:
- Kev tsim kho: PU pob zeb feem ntau yog siv los hloov cov pob zeb ntuj hauv lub tsev facades, kab, thiab arches. Nws kuj tseem siv tau rau sab hauv phab ntsa, pem teb, thiab qab nthab.
- Kev kho kom zoo nkauj hauv tsev: PU pob zeb tuaj yeem siv los ua cov khoom zoo nkauj hauv tsev, xws li rau qhov cub nyob ib puag ncig, mantels, thiab accent walls. Nws kuj tseem siv tau rau kev kho kom zoo nkauj sab nraum zoov, xws li rau vaj phab ntsa thiab dej nta.
- Cov ntawv thov kev lag luam: PU pob zeb tuaj yeem siv rau hauv kev tsim cov khoom lag luam, xws li cov khoom siv tshuab thiab cov khoom siv tsheb.
