Lub Khawv Koob Xim-hloov Umbrella ua haujlwm li cas, thiab Nws Puas Muaj Kev Nyab Xeeb?
Koj tus menyuam lub kaus yooj yim tsuas yog lwm txoj haujlwm rau hnub los nag. Tsis muaj kev zoo siab, ua rau lawv tsis kam tawm mus sab nraud. Yuav ua li cas yog los nag yuav ua tau tej yam yees siv?
Lub kaus hloov xim siv tshwj xeeb hydrochromic number case[^1] uas yog dawb thaum qhuav thiab ua pob tshab thaum ntub. This "magic" cov nyhuv nthuav tawm cov yeeb yuj qauv zais hauv qab, ua rau cov hnub los nag zoo siab thiab lom zem.
Kuv nco txog thawj zaug kuv ntsib hydrochromic number case[^1] cov qauv hauv kuv lub rooj cob qhia. Nws zoo li cov xim dawb yooj yim, tab sis thaum ib tug poob dej tsoo nws, ib tug vibrant xim liab tshwm los hauv qab. Nws zoo li tej khawv koob dawb huv. Tab sis raws li ib tug khoom engineer, Kuv yuav tsum nkag siab txog science. Nws yog ib tug fascinating technology, tab sis siv nws rau cov menyuam yaus cov khoom lag luam muaj ntau tshaj li qhov ua kom yuam kev txias. Kev xaiv ntawm cov khoom siv canopy, hauv qhov no PVC, Nws yog ib qho tseem ceeb rau kev ua kom lub kaus muaj kev nyab xeeb, ruaj, thiab tiag tiag haum rau ib tug me nyuam.
Yog PVC Umbrella yog qhov kev xaiv zoo rau menyuam yaus?
Koj pom lub kaus PVC ntshiab thiab txhawj xeeb. Nws zoo nkaus li tawv thiab koj xav tias nws zoo li ruaj lossis muaj kev nyab xeeb zoo li lub kaus paj ib txwm. Puas yog cov khoom tsim nyog rau menyuam yaus?
A PVC kaus[^2] yog qhov kev xaiv zoo rau cov menyuam yaus thaum tsim khoom raug. Nws cov txiaj ntsig tseem ceeb yog pob tshab, uas tso cai rau cov me nyuam pom lawv mus qhov twg, txhim kho kev nyab xeeb. Niaj hnub nimno PVC kuj tseem ruaj khov.
Raws li tus tsim khoom, Kuv yuav tsum ntsuas qhov zoo thiab qhov tsis zoo ntawm txhua yam khoom siv. Rau xyoo, ntaub (zoo li pongee) yog tus qauv. Tab sis rau cov me nyuam lub kaus, Polyvinyl Chloride (PVC) muab ib qho txiaj ntsig loj: pom kev[^3]. Ib tug menyuam yaus tuaj yeem rub lub dome-zoo li lub canopy ntawm lawv lub taub hau thiab tseem pom txhua yam nyob rau hauv pem hauv ntej ntawm lawv. Qhov no tiv thaiv lawv los ntawm kev tsoo rau hauv cov khoom los yog nce mus rau hauv cov av nkos, kev txhim kho kev nyab xeeb loj. Txawm li cas los, Qhov zoo ntawm PVC yog qhov tseem ceeb. Cov qib qis PVC tuaj yeem ua nkig hauv qhov txias, tawg yooj yim, thiab muaj tshuaj tsw qab muaj zog. Peb xaiv cov qib tshwj xeeb ntawm PVC uas tswj nws qhov yooj yim hauv qhov kub thiab txias thiab ua tau raws li thoob ntiaj teb cov qauv kev nyab xeeb[^4] rau cov khoom me nyuam, xyuas kom nws tsis muaj phthalates teeb meem. Nws hnyav dua li ntaub, yog li peb ua ke nrog lub teeb yuag fiberglass thav duab kom lub kaus yooj yim rau tus menyuam nqa.
PVC vs. Pongee Fabric rau Kids 'Umbrellas
| Feature | PVC (Clear yas) | Pongee (Npuag) | Qhov Zoo Tshaj Plaws Rau Me Nyuam? |
|---|---|---|---|
| Pom kev | Zoo tshaj (Pob tshab) | pluag (Opaque) | PVC, rau kev nyab xeeb. |
| Waterproofing | 100% Tsis ntxeem tau | Dej-resistant txheej | PVC yog inherently waterproof. |
| Qhov hnyav | hnyav dua | Sib dua | Pongee, kom yooj yim nqa. |
| Yooj yim | Siab tawv, tau crease | Yooj yim heev, folds yooj yim | Pongee, rau durability[^5] tawm tsam ntxhib tuav. |
Ntev npaum li cas yog xim-hloov nyhuv?
Koj tus menyuam nyiam qhov kev hloov xim zoo nkauj, tab sis koj tsis ntseeg. Koj txhawj xeeb tus number case tshwj xeeb yuav kos tawm, ploj hauv lub hnub, los yog cia li nres ua hauj lwm tom qab ob peb nag los nag.
Cov nyhuv hloov xim yog xav tsis thoob. Tus hydrochromic number case[^1] yog screen-printed thiab kub-kho, kev sib raug zoo nrog PVC. Nws yog tsim los ua kom lub neej ntev ntawm lub kaus.
Qhov no yog tus naj npawb ib lo lus nug kuv tau txais los ntawm cov neeg siv khoom txog cov tshuab no. The "magic" tsis muaj txiaj ntsig yog tias nws tsuas ua haujlwm rau ib lub lim tiam. Tus durability[^5] los ntawm qhov zoo ntawm tus number case thiab cov txheej txheem thov. Peb tsis yog pleev xim rau xwb. Cov txheej txheem yog ib daim ntawv ntawm industrial screen printing. Ua ntej, cov xim ruaj khov tsim yog luam tawm ntawm PVC. Ces, peb thov cov hydrochromic number case[^1] nyob rau sab saum toj ntawm ib tug zoo mesh screen. Cov kauj ruam kawg thiab tseem ceeb tshaj plaws yog kho. Cov ntawv luam tawm PVC panels raug xa mus los ntawm lub qhov cua kub. Qhov kev tswj cua sov no ruaj ntseg khi cov kua nplaum txheej rau PVC nto. Thaum nws tuaj yeem khawb los ntawm ib qho khoom ntse (ib yam li tej ntawv luam), nws yuav tsis tev, flake, los yog ntxuav tawm hauv nag. Nws tseem yuav rov ua haujlwm tsis tu ncua. Ntev npaum li lub kaus tuaj yeem ntub thiab ces qhuav tag, cov nyhuv yuav ua haujlwm ntxiv mus.
Yuav ua li cas 'Magic' tiag tiag tshwm sim?
Nws zoo li khawv koob, thiab koj xav tias nws tsuas yog ua kom yuam kev xwb. Yuav ua li cas xim tuaj yeem tshwm sim los ntawm cov qauv dawb dawb yooj yim los ntawm kev ntxiv dej? Koj xav nkag siab txog science.
Nws tsis yog khawv koob, nws yog cov khoom siv txuj ci ntse. Tus cwj mem dawb tsis yog xim tiag tiag; Nws yog ib txheej opaque uas ua pob tshab thaum ntub, nthuav tawm cov xim tas mus li luam tawm hauv qab nws.
Cia peb tawg raws nraim qhov tshwm sim ntawm qhov chaw ntawm PVC. Muaj ob txheej txheej sib txawv ntawm cov nyhuv.
Ob-Layer System
- Tus Txheej Txheem: Ua ntej, peb luam lub ci, ruaj khov, thiab muaj yeeb yuj tsim rau ntawm PVC vaj huam sib luag. Nov yog daim duab uas koj pom thaum lub kaus ntub dej. Cov txheej no yog tag nrho cov dej tsis zoo thiab UV-ruaj khov.
- Hydrochromic Txheej: Tom ntej no, peb tshuaj ntsuam-luam qhov tshwj xeeb hydrochromic number case[^1] ncaj qha rau saum cov xim tsim. Tus cwj mem no cov qauv tshuaj ua kom lub teeb tawg thaum nws qhuav, uas ua rau nws zoo li opaque, khoom dawb. Nws kiag li zais cov xim hauv qab.
Thaum los nag tsoo lub kaus, cov dej yog absorbed los ntawm lub hydrochromic number case[^1] txheej. Qhov no hloov nws chemical qauv[^6], ua rau nws nres lub teeb tawg thiab ua pob tshab. Tam sim ntawd, koj tuaj yeem pom txoj cai los ntawm nws mus rau cov xim muaj xim mus tas li hauv qab. Raws li lub kaus dries, cov dej evaporates los ntawm tus number case, nws cov qauv reverts, thiab nws yuav opaque dawb dua, npaj rau hnub los nag tom ntej.
