Kodi Phula Lochokera ku Chomera Limatentha Motani Ndipo N’chifukwa Chiyani Magulu Oyendetsa Misewu Ayenera Kusamala?
Zoona Zokhudza Thermometer: Kodi Phula Lochokera ku Chomera Limatentha Motani?
Ngati munayimapo mayadi angapo kutali ndi chomera chosakaniza ng'oma masana a chilimwe, mukudziwa kale kuti yankho lake ndi " lotentha kwambiri kuposa momwe mukuganizira ." Ma specs ambiri a DOT m'boma amafuna kutentha kwa kusakaniza pakati pa 275 °F ndi 325 °F (135 °C–163 °C) pa chute yodzaza katundu. Mu Chingerezi chosavuta, ndikotentha mokwanira kukazinga nyama yang'ombe yapakatikati yosafunikira m'masekondi osakwana 30. Ndipo inde, mwawerenga bwino zimenezo—275 °F ndiye chocheperako , osati chokulirapo.
N’chifukwa chiyani sitima ya zomera imasakanikirana bwino chonchi?
Simenti ya asphalt (guluu wakuda womwe umagwirira miyala pamodzi) imakhala ndi mawonekedwe ofanana ndi a molasses ozizira kutentha kwa chipinda. Kuti iphimbe mwala uliwonse ndi tinthu ta mchenga, chomangiracho chiyenera kukhala chamadzimadzi. Kutentha kumachepetsa kukhuthala kwakukulu: pa kutentha kulikonse kwa 25 °F, chomangiracho chimakhala pafupifupi kawiri kuposa madzi . Chifukwa chake chomeracho chimakankhira envelopu kuti chitsimikizire kuphimba kwathunthu, makamaka pa ma aggregates okhala ndi mapovu omwe amamwa madziwo. Mfundo yofunika: kusakaniza kukakhala kotentha, kuphimba kumakhala bwino, komanso kulimba kwa msewu.
Kodi Chimachitika N'chiyani Ngati Katundu Wazizira Asanafike Pamalo Ogwirira Ntchito?
Galimoto ikangotuluka pachipata, kutentha kumayamba kuchepa. Kafukufuku wochokera ku National Asphalt Pavement Association (NAPA) akuwonetsa kuchepa kwa 5–7 °F pa kilomita imodzi pa tsiku lozungulira 60 °F. Onjezani mphepo, kuyenda mtunda wautali, kapena kuyenda usiku ndipo delta imakula. Ngati mphasayo ifika pansi pa chipatacho.240 °F (116 °C) , kupanikizika kumakhala kovuta kwambiri. Ma roller sangathenso kutseka malo opanda mpweya, ndipo kusakanizaku kumakhala kofooka, zomwe zimapangitsa kuti pakhale ming'alu komanso kugwedezeka msanga. Kumasulira : malo anu atsopano oimika magalimoto angawoneke ngati ali ndi zaka khumi m'miyezi isanu ndi umodzi.
Momwe Mungasungire Kutentha Pamalo Oyenera—M'kati mwa Katundu
- Tapa galimoto . Tapa yosavuta ya vinyl imachepetsa kutentha ndi 35% pa sitima zonyamula katundu zosakwana makilomita 20.
- Gwiritsani ntchito mabedi otetezedwa ndi kutentha . Mabedi okhala ndi aluminiyamu amasunga kutentha kwa 15–20 °F kokwera poyerekeza ndi chitsulo wamba.
- Konzani nthawi yoperekera zinthu kuti chopakira chisasiye; mutu wa chopakira ukuyenda mosalekeza umathandiza kuti kutentha kusasiyane.
Malangizo a akatswiri:
Musamatulutse zinthu m'magawo . Kutaya theka la katundu, kudikira mphindi khumi, kenako kutaya zina zonse kumapanga pakati pozizira pomwe palibe chopukutira chomwe chingakonze.
Maso a Digito: Masensa a Infrared Kulikonse
Makampani amakono tsopano amaika makamera a infrared pamwamba pa hopper yokweza katundu. Zipangizozi zimayesa malo onse a galimoto iliyonse nthawi yeniyeni, kuyika katundu wocheperako poyerekeza ndi zomwe zafotokozedwa. Deta imayikidwa yokha ku ma dashboard a mitambo, kotero oyang'anira DOT ndi oyang'anira paving amatha kukana gulu lozizira lisanafike pamsewu.
Kodi Kutentha kwa Malo Ozungulira Kumasintha Malo Okhazikika a Chomera?
Inde. M'mawa wa masika kutentha kumafika madigiri 40 Celsius, woyendetsa fakitale akhoza kuponya chandamalecho pa330 °F kuti athetse misewu yozizira yonyamula katundu. Mosiyana ndi zimenezi, masana a Julayi kutentha kwa madigiri 95, malo oimika magalimoto akhoza kubwerera ku290 °F kuti mupewe kutayikira kwa madzi m'chikwama. Taganizirani izi ngati kutenthetsa uvuni wanu pasadakhale: mumasintha choyikiracho kutengera zomwe zikuphika panja.
Kodi Mungatenthetse Mopitirira Muyeso Chosakaniza?
Inde. Kankhirani kusakaniza kudutsa350 °F (177 °C) ndipo simenti ya phula imayamba kusungunuka mofulumira. Chomangiracho chimasanduka chofooka, ndipo utsi wabuluu womwe mukuwona ukuyaka mafuta opepuka . Izi sizimangobweretsa mavuto ku chilengedwe, komanso zimapangitsa kuti msewu ukhale pachiwopsezo cha kutentha m'nyengo yozizira yoyamba. Mwachidule, kutentha kumakhala bwino—mpaka pamene sikunatero.
Zochitika Zenizeni: Ulendo wa Makilomita 20 ku Arizona
Tiyeni tiwerenge manambala. Kutentha kwa chipata cha fakitale: 315 °F. Malo ozungulira: 105 °F. Mtunda wonyamula: makilomita 20 pa liwiro la 55 mph. Pogwiritsa ntchito chitsanzo cha kuziziritsa cha NAPA, kusakaniza kumafika pa285 °F —idakali bwino mkati mwa zenera lolimba. Koma onjezani mphepo yamphamvu ya 15-mph ndipo kutentha kofika kumatsika kufika270 °F Tsopano chotsukira chophwanyika chili ndi mphindi zisanu ndi zitatu zokha kuti chifike pa 92% density mat isanatsike pansi pa 240 °F. Mukaphonya zenera limenelo ndipo mukuthamangitsa mithunzi.
Ndalama Zofunika: Kodi Cool Mix Imawononga Ndalama Zingati?
Katundu umodzi wa matani 20 womwe ungafikire pansi pa zomwe zafotokozedwazo ukhoza kuwonongera kontrakitala ndalama:
| Chinthu | Mtengo |
|---|---|
| Kuchotsa ndi kusintha | $1,200 |
| Kupukuta ndi kuphimba pamwamba | $800 |
| Zilango za DOT | $500 |
| Kuwonekera konse | $2,500 pa galimoto imodzi |
Mukachulukitsa zimenezo ndi magalimoto khumi patsiku, mukuyang'ana $25,000 yokonzanso musanadye nkhomaliro. Mwadzidzidzi, kukweza kamera ya infrared ya $300 kumeneko kumawoneka ngati kusintha pang'ono.
Mfundo Zofunika Kwambiri kwa Magulu Oyenda Pamadzi
Kumbukirani, kutentha ndi cholinga chosuntha . Yang'anirani malo omwe chomera chimayambira, mtunda wonyamulira katundu, liwiro la mphepo, ndi kutentha kwa malo ozungulira nthawi yeniyeni. Chitani chilichonse ngati pizza yotentha yotumizidwa: ikafika mwachangu komanso yotentha kwambiri kwa kasitomala, aliyense amakhala wosangalala kwambiri.
