Yuav ua li cas txiav txim siab qhov zoo ntawm lub qhov rooj aluminium qhov rooj thiab qhov rai?
1, kev siv cov khoom siv qis-cov cuab yeej tsis muaj txheej txheem ntawm cov hom phiaj yas, polyvinyl chloride (PVC) rwb thaiv tsev cov ntaub ntawv (tom qab ntawv hu ua PVC rwb thaiv tsev daim iav), los hloov cov European-lees iav fiber ntau xyoo lawm, Siv tam polyamide nylon ( PA66) cov khoom thaiv rwb thaiv tsev (tom qab ntawv hu ua nylon 66 rwb thaiv tsev sawb). Vim tias txoj kab nthuav dav coefficient ntawm PVC (8.3 * 10-5K-1), nws tseem nyob deb ntawm cov linear expansion coefficient ntawm aluminium alloy (2.35 * 10-5K-1), thiab nws lub zog yog tsawg (tsuas yog li 30N / mm2 )). Ntau qhov tsis xws luag xws li tshav kub tsis zoo tiv thaiv (80 ° C) thiab ua haujlwm tsis zoo los tiv thaiv kev laus. Qhov tshwm sim yog qhov sib tsoo choj txhuas profile tom qab cov kab sib txuas yog ua los ntawm PVC rwb thaiv tsev txoj hlua, thiab lub qhov rooj cua sov thiab cov qhov rai ua tom qab kev teeb tsa thiab kev siv tiag, vim thermal nthuav thiab paug, yuav ua rau cov PVC rwb thaiv tsev sawb pom nyob rau hauv tawg choj txhuas profile. Xoob lossis txawm tias muaj qhov cuam tshuam tag, ua rau daim ntawv xoob thiab deform, yog li ua rau lub airtightness thiab watertightness ntawm lub qhov rooj thiab qhov rais, thiab ua rau tag nrho daim ntawv xoob thiab tsis huv.
2, Tam sim no, nyob rau hauv rooj plaub tawg ntawm lub qhov rooj aluminium qhov rooj thiab qhov rai, muaj ntau lub chaw lag luam uas siv cov txheej txheem rwb thaiv tsev ntawm cov nylon 66 rwb thaiv tsev tawm los ua daim ntawv twv, thiab tom qab ntawd siv cov PVC rwb thaiv tsev sawb tom qab cov ntawv twv, lossis nylon rwb thaiv tsev. Sawb yeej tau txheej txheem, los yog sib xyaw nrog txawv teb nylon 66 rwb thaiv tsev ib daim hlab thiab PVC, lossis lwm yam txheej txheem rwb thaiv tsev. Lub nylon txawv teb chaws rwb thaiv tsev txoj kab hluav taws xob muaj lub cim ntaus cim sab nraud rau "pov thawj" cov qib "zoo" ntawm cov rwb thaiv tsev ntxaij siv. Qhov no "hla hiav txwv me me" muaj qhov muaj peev xwm zais. Tus tswv ntawm lub qhov rooj aluminium tawg thiab lub qhov rai tuaj yeem pom tau tsuas yog ua ntej qhov profile tau ua tiav, vim tias tsuas yog ob lub rhaub hluav taws xob kub ntawm lub sijhawm tam sim no yog qhov pom tseeb.
3, Cov khoom siv ntawm cov rwb thaiv tsev thaiv tau yog lub hauv paus rau qhov zoo ntawm qhov thaiv ntawm cov qhov rooj thiab lub qhov rais, tab sis nws yog los ntawm tsis muaj qhov tsuas yog kev lees paub. Nyob rau hauv 2003, nylon rwb thaiv tsev ib daim hlab pib kom tau muaj. Txhawm rau txo tus nqi, nylon rwb thaiv tsev ib daim hlab siv cov khoom siv ntxhia (feem ntau hu ua fillers) los hloov tag nrho lossis ib feem ntawm cov iav fiber los sau polyamide nylon rau kev ua. Cov kab hluav taws xob zoo li no piv tsis tau rau iav fiber tam nylon 66 rwb thaiv tsev ib daim hlab ua cov ntaub siv tshuab, muaj zog tiv tshav kub, thiab tiv taus laus.
4, qee qhov tawg choj txhuas lub qhov rooj thiab lub qhov rais kev lag luam hauv kev kawm tag nrho thiab paub tseeb ntawm PVC rwb thaiv tsev ib daim hlab, cov nylon rwb thaiv tsev ib daim hlab thiab txawv teb nylon 66 rwb thaiv tsev ib daim hlab, tom qab kev ua tau zoo dua qhov sib txawv ntawm peb, coj kev pom zoo ntawm kev lag luam thiab kev tuav pov hwm: lub qhov rai ncej txhuas profile yog ua los ntawm cov ntaub ntawv zoo thiab tsis tshua muaj nqi PVC, lossis nylon rwb thaiv tsev sawb, thiab sash aluminium profile yog ua los ntawm cov khoom zoo nylon 66 rwb thaiv tsev sawb. Lawv ntseeg tias txhuas txheej ntawm lub qhov rais thav duab tau tsau rau ntawm phab ntsa, thiab tsis muaj teeb meem loj txawm tias muaj kev pheej hmoo tsis zoo, thiab cov ntaub ntawv aluminium ntawm lub qhov rai sash tau txav mus los thiab ua lub zog ib leeg, yog li nws tsis tuaj yeem ntshai ntawm qhov tsis zoo. Cov.
