Raws li polystyrene yog ua rau lawv tus kheej txhais tes

Kev siv cov polystyrene nyob rau hauv kev tsim kho ntawm ib tug xov tooj ntawm zoo txuam nrog tej yam ntxwv ntawm lub substance. Nws yog ib tug ntau yam ntaub ntawv uas yog feem ntau siv rau kev ua hauj lwm ntsig txog kev sov, nws yog check, muaj tsawg thermal conductivity thiab zoo kuj huab kub, li no yuav tsis tau qhov kev txiav txim ntawm cov hluav taws. Thiab vim yog lub me me luj ntawm polystyrene, nrog nws tus kheej ob txhais tes ua, ib qho yooj yim mus siv, tsawg heev shrinkage ntawm lub tsev. Muaj pes tsawg leeg ntawm tib cov ntaub ntawv uas, feem ntau yog dej, muab tub lim thiab phau ntawv.

Vim lub fact tias polystyrene yog ib tug honeycomb qauv, nws yog ib qho zoo heev tshav kub insulating cov ntaub ntawv uas siv nyob rau hauv niaj hnub siv. Tsim cov tib penopolistirolbeton tus kheej ob txhais tes yog tsis nyuaj li thaum tej zaum nws yuav zoo li thaum xub thawj siab ib muag. Yog hais tias lub tswv yim ua raws li tej yam tau muab sij hawm, thiab txawm ntau nws ratios, qhov zoo ntawm lub resulting cov ntaub ntawv uas tsis zam kev rau lub Hoobkas. Tom qab tag nrho, nws yog tsim los ntawm dej, uas tau tsis muaj teeb meem, pellets ntawm npaus thiab ntau hom xis mas. Feem ntau, nws yog tog twg los ua vaj tse los yog plaster. Nyob rau hauv thiaj li yuav ua rau kom cov efficiency los ntawm kev ua polystyrene nrog koj ob txhais tes, koj muaj peev xwm siv rau tag nrho cov xaiv ntawm additives.

Yuav ua li cas yuav tsum tau rau qhov siv thiab ua

Tej uas nws kim heev nyob rau hauv kev siv niaj hnub siv ntawm cov khoom no yog piav los ntawm tus fact tias cov polystyrene nqi yog tsawg tshaj li lwm yam kev tsim kho cov ntaub ntawv, thiab qhov zoo tshaj yog, txawm li cas los, tsis muaj zuj zus. Thiab los ntawm kev ua cov styrofoam nyob rau hauv tsev, koj muaj peev xwm cawm txawm ntau rau nws cov nqi. Yuav kom npaj no cov ntaub ntawv uas, koj xav tau ib tug txheej ntawm cov cuab yeej, uas muaj xws li cov pa duav thiab ib tug xis mas tov.

Thaum polystyrene yog ua rau lawv tus kheej txhais tes, muaj peev xwm yuav siv tau nyob rau hauv tas li ntawd mus rau saum toj Cheebtsam thiab quartz xuab zeb, txhab polystyrene nyob rau hauv granules. Nyob ntawm seb dab tsi zoo ntawm kev ceev yuav tsum kawg yuav ua vaj tse, yuav tsum tau ceev faj kom xaiv qhov luaj li cas thiab ntau npaum ntawm tag nrho lub Cheebtsam. Yog li ntawd, rau qhov siv thiab ua cov polystyrene qib D550 mixed xuab zeb thiab xis mas nyob rau hauv lub ratio ntawm ib tug mus rau ib qho, thiab ces ntxiv mus rau lub sib tov foamed polystyrene, feem ntau yog muab tso rau 0.5 cubic meters. Tom qab tag nrho cov khoom xyaw tov, lub resulting muab tshuaj txhuam yog muab tso rau hauv ib tug tov khoom thiab muaj xws li nws nyob rau hauv qhov nruab nrab lub hwj chim. Thaum lub sij hawm kev lag luam, dej yog ntxiv, ib, lossi stirring tag nrho cov sib tov.

Thaum polystyrene yog npaj txhij rau kev siv

Yuav kom npaj polystyrene nrog lawv txhais tes, ib yog siv vim hais tias nws imparts dej pleev cov tshuaj thaj chaw ntawm lub sib tov. Tom qab stirring tas, lub resulting sib tov yog poured mus rau hauv cov ntaub ntawv uas muaj peev xwm muab tau yooj yim los ntawm cov boards, khob lawv ua ke, thiab kho lub hauv lubricating roj. Teem lub sij hawm ntawm lub sib tov yog feem ntau hais txog 24-25 teev, tom qab uas thaiv rho los ntawm cov pwm thiab tso cai rau qhuav nyob rau hauv ib qhov chaw txias. Tom qab ob los yog peb lub lis piam lawv npaj txhij rau kev siv.
