cov ntaub ntawv Polymer niaj hnub no tau siv dav hauv kev tsim vaj tsev thiab cov khoom siv rau ntau lub hom phiaj. Ntawm lawv, polycarbonate yog ib lub vaj huam sib luag uas muaj ob lossis peb txheej, ntawm cov uas muaj longitudinally oriented stiffeners. Vim yog cov qauv ntawm tes, nws muaj peev xwm ua tiav lub zog txhua yam ntawm canvas nrog qhov hnyav me me.
Kev piav qhia ntawm polycarbonate
Cellular polycarbonate hauv ntu ntu zoo li honeycombs, uas tuaj yeem ua daim duab peb sab lossis duab plaub. Cov khoom siv raw rau cov khoom siv no yog granulated polycarbonate, uas tuaj yeem tau txais los ntawm kev sib xyaw ntawm dihydroxy compounds thiab polyesters ntawm carbonic acid. Cov khoom siv yog tsim raws li TU-2256-001-54141872-2006, txawm li cas los xij, qhov ntev tau teev tseg hauv cov cai no yuav txawv raws li qhov xav tau ntawm cov neeg siv khoom. Cov tsis muaj stiffeners yog txiav txim los ntawm cov chaw tsim khoom, qhov siab tshaj plaws tso cai sib txawv tsis yogntsia.
Kub qhov kev siv
Cellular polycarbonate muaj qhov ua haujlwm siab rau qhov tsis zoo ib puag ncig. Kev tswj hwm kub ntawm kev siv yog nyob ntawm hom khoom siv, ua raws li cov cai ntawm kev siv tshuab thiab cov khoom siv raw zoo. Rau ntau hom panels, qhov ntsuas no txawv ntawm -40 txog +130 degrees. Qee hom ntawm cov khoom piav qhia tuaj yeem tiv taus qhov kub thiab txias, uas yog sib npaug ntawm -100 degrees. Nyob rau hauv rooj plaub no, tus qauv tsis raug puas tsuaj. Thaum raug kub los yog txias, cov kev hloov hauv linear qhov ntev yuav tshwm sim. Qhov tso cai nthuav dav yuav tsum tsis txhob ntau tshaj 3 millimeters ib 1 meter, hais txog qhov dav thiab ntev ntawm daim ntawv. Vim qhov tseeb tias cov khoom siv polycarbonate yog tus cwj pwm los ntawm kev nthuav dav thermal loj, nws yuav tsum tau nruab nrog kev tshem tawm kom tsim nyog.
Tshuaj tiv thaiv
Thaum siv cov khoom tiav, nws yuav tsum tau coj mus rau hauv tus account tias lawv raug rau txhua yam kev puas tsuaj. Polycarbonate yog ib yam khoom uas muaj kev tiv thaiv zoo rau ntau cov tshuaj. Txawm li cas los xij, cov nplooj ntawv tsis pom zoo yog tias lawv tuaj yeem raug tua los ntawm cov tshuaj tua kab, cov cement sib tov, PVC-plasticized tshuaj, pob zeb, cov tshuaj ntxuav tes, halogen thiab aromatic solvents, ammonia, acetic acid thiab alkali raws li sealants, ethyl cawv daws.
Sustainabilitypolycarbonate rau tshuaj compounds
Polycarbonate yog cov khoom siv uas yuav ua rau muaj kev cuam tshuam ntawm cov tshuaj ntsev nrog cov tshuaj tiv thaiv tsis zoo, nrog rau cov ntxhia hauv cov kua qaub. Cov vaj huam sib luag tsis ntshai ntawm kev txo cov neeg ua haujlwm thiab oxidizing cov neeg ua haujlwm, nrog rau cov dej cawv daws, methanol yog qhov zam. Thaum txhim kho canvases, nws yuav tsum tau siv silicone sealants thiab sealing ntsiab tshwj xeeb uas tsim rau lawv.
Mechanical zog
Polycarbonate muaj peev xwm ua rau muaj kev ntxhov siab rau txhua yam. Nws yuav tsum raug coj mus rau hauv tus account tias qhov saum npoo tuaj yeem raug cuam tshuam rau kev ua haujlwm ntev ntev nrog cov khoom me me xws li xuab zeb. Nyob rau hauv rooj plaub no, kev tsim ntawm khawb yog ua tau thaum raug cov ntaub ntawv ntxhib uas muaj txaus hardness. Lub zog txhua yam yuav nyob ntawm tus qauv thiab hom. Yog tias peb tham txog lub zog tensile, ces cov khoom hwm muaj qhov sib npaug ntawm 60 MPa. Lub zog tawm los ntawm tib qib yog 70 MPa. Lub zog cuam tshuam yog 65 kJ / mm. Cov chaw tsim khoom muab kev lav 10-xyoo kev ua tau zoo, muab cov nplooj ntawv tau teeb tsa kom raug thiab siv cov fasteners tshwj xeeb.
Thickness parameters thiab tshwj xeeb gravity
Technology cuam tshuam txog kev tsim polycarbonate ntawm ntau qhov sib txawv. Tam sim no ntawm kev ua lag luamcov ntaub ntawv hauv tsev, koj tuaj yeem pom cov ntawv uas nws thickness txawv ntawm 4 mus rau 25 millimeters. Txhua yam ntawm no muaj ib tug txawv internal qauv. Qhov ceev ntawm polycarbonate yog 1.2 kilograms ib cubic meter. Rau canvases, qhov ntsuas no nyob ntawm seb muaj pes tsawg tus txheej, thickness ntawm cov panels thiab qhov deb ntawm cov stiffeners. Nrog ib daim ntawv tuab ntawm 4 hli, tus naj npawb ntawm phab ntsa yog txwv rau ob, thaum qhov kev ncua deb ntawm cov stiffeners yog 6 hli. Nrog lub thickness ntawm 25 millimeters, cov phab ntsa yog 5, thaum lub suab ntawm cov tav yog 20.
Sun resistant
Polycarbonate yog cov khoom siv uas tuaj yeem lav kev tiv thaiv hluav taws xob ruaj khov. Txhawm rau ua tiav cov txiaj ntsig no, txheej txheej stabilizing yog siv rau daim ntawv thaum lub sijhawm tsim khoom. Cov tshuab no muab kev pabcuam lub neej ntawm 10 xyoo. Tsis muaj lub caij nyoog ntawm tev tawm cov txheej tiv thaiv los ntawm cov khoom siv nws tus kheej, vim tias cov polymer tau ntseeg tau fused rau hauv paus. Thaum txhim kho daim ntawv, nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account qhov tseeb tias cov txheej txheem tsim los tiv thaiv lub hnub ci hluav taws xob yuav tsum tig mus rau sab nraud. Lub teeb kis tau tus mob nyob ntawm cov xim, piv txwv li, cov ntawv tsis muaj xim muaj qhov ntsuas no hauv thaj tsam ntawm 83 txog 90 feem pua. Cov xim pob tshab tsis muaj ntau tshaj li 65 feem pua, tab sis lub teeb kis tau zoo sib txawv.
Cov yam ntxwv ntawm qhov cua sov
Thaum tsim lub tsev cog khoom polycarbonate, yam khoom twg yog nws, koj yuav tsum paub ua ntej. Nwsmuaj cov thermal rwb thaiv tsev zoo heev. Lub tshav kub tsis kam ntawm cov khoom no yog ua tiav vim huab cua nyob rau hauv thiab vim li cas lub canvas muaj ib tug tseem ceeb thermal kuj. Lub tshav kub hloov coefficient yuav nyob ntawm tus qauv thiab thickness ntawm daim ntawv. Qhov ntsuas no txawv ntawm 4.1 txog 1.4 W / (m² K). Thawj tus lej yog qhov tseeb rau lub vev xaib uas yog 4 hli tuab, thaum tus lej thib ob yog rau daim ntawv 32 hli. Polycarbonate yog cov yas uas siv tau thaum tsim nyog los ua ke zoo heev thermal rwb thaiv tsev zog thiab siab transparency.
Hluav taws kub
Polycarbonate suav hais tias tiv taus qhov kub thiab txias, nws yog nyob rau hauv qeb B1, uas, raws li European kev faib tawm, txhais tau hais tias cov nplaim hluav taws kub hnyiab thiab nws tus kheej tua cov khoom. Thaum kub hnyiab, nws tsis tawm cov pa phem thiab tsis muaj kev phom sij rau tib neeg. Nrog rau qhov piav qhia thermal nyhuv, raws li qhov qhib nplaim taws, cov txheej txheem ntawm kev tsim los ntawm qhov thiab kev puas tsuaj ntawm cov qauv pib. Cov khoom pib txo qis hauv cheeb tsam.
Lub neej
Monolithic polycarbonate yog cov khoom siv uas nws cov tuam txhab lav kev khaws cia cov yam ntxwv zoo ntawm cov khoom rau 10 xyoo. Qhov no muaj tseeb yog tias cov kev teeb tsa thiab kev ua haujlwm tau ua raws. Yog tias koj tsis tso cai rau kev puas tsuaj rau sab nrauv, koj tuaj yeem txuas lub neej ntawm lub vaj huam sib luag. Txwv tsis pub, kev puas tsuaj ntxov ntawm lub vev xaib yuav tshwm sim. Nyob rau hauv cov cheeb tsam uas muaj kev pheej hmoo ntawm kev puas tsuaj rau txhua yam,cov nplooj ntawv nrog lub thickness ntawm 16 hli los yog ntau tshaj yuav tsum tau siv. Thaum lub sij hawm kev teeb tsa, nws yog ib qho tsim nyog yuav tsum tau coj mus rau hauv tus account qhov tsis suav nrog qhov muaj peev xwm ntawm kev sib cuag nrog cov khoom uas tuaj yeem ua rau muaj kev puas tsuaj hauv daim ntawv ntawm kev puas tsuaj.
Noise isolation performance
Cov qauv honeycomb muab qhov sib kis tau zoo heev, uas qhia tau hais tias cov panels muaj lub suab zoo heev, uas nyob ntawm seb hom ntawv thiab nws cov qauv sab hauv. Yog li, yog hais tias peb tham txog multilayer cellular polycarbonate, lub web thickness uas yog 16 millimeters los yog ntau tshaj, lub attenuation ntawm lub suab yoj tshwm sim nyob rau hauv ntau ntawm 10 mus rau 21 dB.
Zoo kawg
Nws tuaj yeem hais tias plexiglass yog polycarbonate nrog cov yam ntxwv tsis zoo. Cov khoom siv thib ob muaj lub zog ntau dua thiab kev ntseeg siab; rau cov no thiab ntau lwm yam zoo, cov qauv honeycomb raug xaiv ntau dua. Qhov no kuj yog vim qhov tseeb tias polycarbonate siv ntau qhov chaw, suav nrog kev tsim kho, nrog rau kev kho. Cov neeg siv khoom ntiag tug xaiv nws los tsim cov canopies, tsev cog khoom, gazebos thiab ntau ntxiv. Cov qauv ntawm nws tau txais lub teeb thiab tsis tas yuav tsum muaj kev tsim kho ntawm lub hauv paus tshwj xeeb. Qhov no txo tus nqi ntawm cov txheej txheem thiab ua kom yooj yim rau kev ua haujlwm.
