Thovu la Melamine ndi chinthu chogwira ntchito bwino chomwe chili ndi mphamvu zabwino zochepetsera phokoso komanso kuchepetsa phokoso, komanso chimaletsa moto. Chikagwiritsidwa ntchito poteteza kutentha, chimathandiza kulamulira kutentha ndi kutentha komwe kumasamutsidwa kuti chikhale chotetezeka komanso chotonthoza. Mphamvu zake zoteteza phokoso ndi kugwedezeka zimapangitsa kuti aliyense akhale chete. M'nkhaniyi, tikambirana mwatsatanetsatane chifukwa chake thovu la melamine ndi labwino kwambiri poteteza kutentha komanso phokoso.
Kodi thovu la melamine ndi chiyani?
Melamine thovu ndi yosalala, yosinthika, yotsika kachulukidwe, zinthu zazing'ono zazing'ono zopangidwa kuchokera ku melamine resin, polima wa thermosetting wopangidwa ndi melamine ndi formaldehyde. Kuti apange thovu la melamine, utomoni wa melamine umatulutsa thovu ndi wowuzira ndikuchiritsidwa. Chotsatira chake ndi chinthu chokhala ndi mawonekedwe apadera atatu-dimensional omwe amadziwika ndi njira yolumikizirana kwambiri (yotseguka-selo).
Kuphatikizika kwakukulu kwamtundu wa thovu la melamine kumapangitsa kuti zisagonjetse kuzizira komanso kusasunthika kwambiri kuposa zithovu zachikhalidwe monga polyethylene, polypropylene ndi polyurethane, zomwe sizimalumikizana pang'ono. Zithovu za melamine zimatha kupirira kutentha kwambiri (mpaka +240 ° C) ndi kutsika (mpaka -180 ° C) kutentha kwa nthawi yayitali ndikusunga bata ndi magwiridwe antchito.
Ntchito ndi katundu wa melamine thovu
Mapepala a thovu a Melamine akhala chisankho chomaliza chamitundu yosiyanasiyana yamafuta otenthetsera komanso omvera chifukwa cha magwiridwe antchito awo abwino komanso katundu. Ubwino wa melamine ndi wapamwamba kwambiri poyerekeza ndi zida zina zotetezera. Zina mwazinthu ndi zinthu zomwe zimatanthauzira kutsekeka kwa ma cell otseguka ndi awa:
-Wopepuka
-Kuzimitsa moto
-Kusamva madzi -Chithovu cha Hydrophobic chokha
- Kuchuluka kwa moto woyaka, kutulutsa utsi komanso kawopsedwe
-Zosavuta kusintha
-Zokhazikika, komanso zosinthika
1. Wopepuka
Kugwiritsa ntchito zida zotchinjiriza zopepuka kumapereka maubwino ambiri pazinthu zosiyanasiyana. Amachepetsa ndalama zopangira ndi nthawi komanso amapereka kusinthasintha kwakukulu. Ndi kulemera kwa zosakwana 0.75 pounds pa kiyubiki phazi (lb/ft3), thovu melamine nthawi zambiri kutchinjiriza kusankha pamene kulemera kwa zinthu kungakhale ndi chikoka chachikulu pa ntchito. Tangoganizani za mlengalenga ndi ntchito zankhondo komwe kulemera kuli kofunikira.
Chifukwa cha mawonekedwe ake a cell otseguka, thovu la melamine ndi lopepuka kuposa kusungunula kwanthawi zonse kwanthawi yayitali komanso kwamayimbidwe ndipo limatha kufanana mosavuta ndi kutsekemera kokhuthala.
2. Kuchedwa kwamoto
Pazifukwa zachitetezo, kutchinjiriza kulikonse kuyenera kukhala koletsa moto. Kupatula apo, iyi ndiye ntchito yoyamba ya insulation. Zida zoletsa moto zimalepheretsa kufalikira kwa moto ndikuteteza nyumba ndi ntchito zina kuti zisawonongeke. Gulu la nayitrogeni mu thovu la melamine silingapse ndi moto ndipo limapondereza utsi, likukwaniritsa miyezo ya chitetezo cha UL 94 cha flammability. Zimatsutsana ndi kutentha kwakukulu popanda kusungunuka kapena kupanga madontho oyaka moto ndipo ndizoyenera malo otetezera moto omwe ali ndi zofunikira zapamwamba.
3. Chosalowa madzi
Kawirikawiri, thovu la melamine lokhazikika silimalowa madzi. Chifukwa chake, ndibwino kugwiritsa ntchito thovu la melamine lopanda madzi ngati limagwiritsidwa ntchito pomwe chiopsezo chokumana ndi madzi ndi chinyezi chili chachikulu. Thovu la Melamine, monga hydrophobic melamine, limakutidwa ndi utomoni woletsa madzi womwe umachiritsidwa ndi kuwala kwa UV, zomwe zimapangitsa kuti zisalowe m'madzi. Mitundu ina imadutsa mu plasma vaporized kuti iwonjezere kukana kwawo madzi. Thovu la melamine lopanda madzi limalimbikitsidwa makamaka kuti ligwiritsidwe ntchito poteteza kutentha ndi kutentha m'malo omwe amafunika kukana chinyezi kwambiri, kufalikira kwa moto pang'ono, ndi zina zotero. Izi ndi zomwe zimachitika, mwachitsanzo, ndi ma fuselage ndi makoma a ndege, mapaipi a ECS ndi magalimoto atsopano amphamvu.
4. Kufalikira kwa moto wochepa, kutulutsa utsi ndi poizoni
Kutengera kupanikizika ndi kutentha kolowera, moto kapena lawi limatha kufalikira (kufalikira) ndi conduction, convection kapena radiation. Mosasamala kanthu za njira yomwe imagwiritsidwa ntchito, kufalikira kwa lawi kumatha kukhala kowononga, kubweretsa kuwonongeka kosasinthika ndikupanga ngozi zambiri zachitetezo. Kutsekereza koyenera kungathandize kuletsa kufalikira kwa moto ndikuwonjezera chitetezo. Chithovu cha melamine chimadziwika chifukwa cha kufalikira kwamoto wochepa m'malo otentha kwambiri komanso kugwiritsa ntchito kwake. Mosiyana ndi zimenezi, ikakhala ndi kutentha kwambiri, imayaka, imachepetsa mpweya wa okosijeni ndi kufalikira kwa moto pang'onopang'ono kuti chitetezo chiwonjezeke.
5. Mosavuta Customizable
Insulation yabwino iyenera kusinthidwa mosavuta kuti igwirizane ndi mitundu yosiyanasiyana ya insulation. Chithovu cha Melamine ndi chimodzi mwazinthu zomwe mungasinthire makonda. Ili ndi mawonekedwe otseguka omwe amathandizira kuti azisinthasintha komanso kuti azidula mosavuta. Imapezeka m'mawonekedwe, mitundu, ndi makulidwe osiyanasiyana kuti ikwaniritse zomwe ogwiritsa ntchito akufuna. Kuphatikiza apo, mutha kudziwa kachulukidwe ka thovu ka melamine pamatenthedwe anu kapena mamvekedwe. Kaya mukufuna kuigwiritsa ntchito powongolera kutentha kapena ngati thovu lamayimbidwe, zinthuzo ndizosintha kwambiri kuti zikwaniritse zosowa zanu zotsekera.
6. Semi-rigid, komanso kusinthasintha
Zodabwitsa ndizakuti, thovu la melamine limasinthasintha ngakhale kuti ndi lolimba. Izi zili choncho chifukwa kamangidwe kake ka mamolekyu ndi kapangidwe kake kamapangitsa kuti munthu azitha kusinthasintha ndipo amapunduka pokanikizidwa kapena kupindika osataya mawonekedwe ake. Kusinthasintha kumeneku kumapangitsa kuti thovu la melamine lizigwirizana ndi malo osakhazikika ndikukwaniritsa zofunikira zosiyanasiyana zotenthetsera komanso zoyimbira, ndikusunga umphumphu komanso kuchita bwino.
Kugwiritsa ntchito thovu la Melamine:
Chithovu cha Melamine ndichoyenera kwambiri kugwiritsa ntchito ma acoustic ndi matenthedwe otsekemera. Ili ndi ma acoustic abwino kwambiri, moto- komanso zoletsa moto. Kuphatikiza apo, ndizopepuka, zosunthika komanso zokhazikika.
Timayang'ana kwambiri ntchito zake ziwiri zazikuluzikulu zatsopano:
Kutentha kwamphamvu
Kusinthasintha kwa kutentha ndi koopsa kwa chitetezo ndipo kungayambitse kuwonongeka kosasinthika chifukwa cha kutentha kwakukulu. Kutsekemera kwa thovu la melamine kumakhala ndi nayitrogeni wambiri, zomwe zimathandiza kuwongolera kutentha kwa conduction ndi ma radiation, potero kumawonjezera chitetezo. Kutsika kwake kwamafuta kumachedwetsa kufalikira kwa lawi ndi kusamutsa kutentha popanda kufunikira kwa zowonjezera zoletsa moto.
Mafakitale ambiri, monga zakuthambo, zoyendera anthu onse ndi matelefoni, amazigwiritsa ntchito kuti apititse patsogolo chitetezo pamapulogalamu omwe amafunikira kukana kutentha kwambiri komanso kutsika kwamoto ndi utsi. Mwachitsanzo, thovu la melamine lingagwiritsidwe ntchito kutsekereza: zipinda zamagalimoto ndi injini, ma ducts mu machitidwe a HVAC, makoma a ndege ndi ma fuselages, ndi zina zambiri.
Mayamwidwe amawu
Chithovu cha melamine ndi chodziwikiratu chifukwa choyamwa mawu. Ili ndi mawonekedwe a ma cell ang'onoang'ono omwe amatenga mafunde amawu, amalekanitsa kugwedezeka ndikuletsa phokoso kuti lisabwerenso pansi, makoma ndi kudenga. Katunduyu amapangitsa thovu la melamine kukhala insulator yabwino yamafakitale, zoyendera, zakuthambo, zomanga ndi zina.
Mwachitsanzo, thovu la melamine lingagwiritsidwe ntchito kutsitsa phokoso lopangidwa ndi mafani ndi ma ducts mumakina a HVAC. Itha kugwiritsidwanso ntchito kutsekereza zipinda za injini, zitseko, makoma, ndi magawo oyendetsa ndi okwera sitima.
Chidule
Mosakayikira thovu la melamine ndi njira yabwino kwambiri yothetsera matenthedwe ndi ma acoustic insulation applications. Ndi yopepuka, yoletsa moto, yosalowa madzi ndipo ili ndi mawonekedwe abwino kwambiri amawu. Imatha kupirira kutentha kwambiri ndikuwongolera phokoso ndi kugwedezeka kuti pakhale malo abwino komanso opanda phokoso. Amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuti akwaniritse zofunikira zachitetezo chapamwamba.
